THE MEANING OF THE BRACKETS: throughout my stories (except my first one, "Anytime Lisa,") I'll be putting brackets around certain phrases. Think of these phrases as links. I write excruciatingly slowly, but over time, I plan to post a story whose title corresponds to every bracketed phrase. Whatever the person who's talking says that's bracketed, you can go to that story to read more about what they just mentioned. Try looking up one of my other stories and you should get the idea. It's sort of a Star Wars "continuous universe" kind of thing. Okay, thanks for indulging me. And just for the record, I love feedback and I'd love to chat.

The day my sister Lisa was coming home, I woke up hard as a rock.

It may have had something to do with the dream I'd just been having about her going down on me, or the fact that it had been a whole year since I'd last gotten to push myself into my big sister's butt. Either way, I looked pretty foolish plodding downstairs to get breakfast wearing nothing but my distended PJ bottoms.

Normally my morning wood drops off pretty quickly, but I couldn't keep my mind from wandering back to the previous summer, when Lisa had taken my virginity and shown me a kind of love that I'd never known existed. It was something animal and powerful; a gasoline mixture of love and lust that you don't see in the movies or read about in books (at least not the type of books they assign in high school English). After that, whenever I needed to get off she was there; I called her my [Anytime Lisa]. We'd kept giving in to each other until September, when she just disappeared--as Lisa has a tendency to do.

Which, I'll admit, stung. I felt so much younger then. Lisa had opened my eyes to something, and because of it she'd become not just my big sister, but my confidant, teacher, guide, sexual partner, and, I believed, the love of my life. Still do, actually.

And even though I put the lessons she taught me to good use over the course of the school year (mostly in [Drama Club]), nothing was ever quite the same as fucking my big sis. So you can imagine my excitement when she'd written the family a few days earlier and let us all know she was going to be home for her baby brother's birthday come hell or high water. Ever since, I'd been daydreaming non-stop about the taste of her skin, her fiery red hair and the look of pure bliss that filled her big green eyes whenever I slipped into her insatiable little butthole and rode her as hard as I could.

It was throbbing by the time I was halfway down the stairs to the family room. I could already tell this one wasn't going to take care of itself, and there was no telling when Lisa would be coming home, let alone when we could sneak away and get our hands on each other. Breakfast could wait, I decided; I needed some manual release.

As if on cue, I suddenly heard the faint sound of my mother speaking in a strained voice. At first I reflexively reached down in a feeble attempt to hide my stiffy, but then I realized that the sounds emanating from my parents' room down the hall weren't directed at me. A-ha! I grinned. Mom was getting eaten out.

Ever since I'd discovered that by unscrewing an AC vent cover in the guest bedroom I could gain easy access to my parents' closet, I'd been exploiting the fact. When I was younger I sneaked in there on late December nights to see what Christmas presents they'd picked out. Once I got a little older though, I found the wood-slat closet doors provided a perfect view whenever my Mom and Dad had sex.

Growing up, I had some of my most intense orgasms beating off while watching Dad slam Mom from behind. The taboo of it made me cum much harder than usual, and it was quite a stroke of luck that they should be "paying bills" (as they called it) right when I needed to relieve my swelling boner. Part of me wondered why Dad wasn't at work by now, but I wasn't about to look a gift-voyeurism in the mouth.

As I silently wriggled through the small hole and pushed past my Dad's loafers, I could hear my mom's impassioned voice:

"Oh God yeah, do that. Right there. Oh, fuck, that's so good. Eat it, eat it all up sweetheart."

I maneuvered into a squatting position and reached down to unbutton the front of my PJ's, but stopped suddenly when I heard another familiar voice say "You like that? Are you gonna come for me?" Familiar, but definitely not Dad's. In fact, not even male.

I couldn't believe my ears, but when I looked out through the slits in the closet door, what my mind told me was impossible was impossible to deny: My cousin Sam, who wasn't even supposed to be here for six hours, was eating out my Mom. Not just eating her out either; she was giving it her all, lapping frantically at Mom's gleaming pussy. My favorite, inevitably cheerful, inviolably sweet, and adorably plump lesbian cousin was about to taste my Mom's cum.

For a second I just stared, trying to soak in the whole image. My parents' big bed, with the modern gray comforter thrown back to reveal my Mom, legs spread wide, still asking for more as she pushed Sam's head into her pussy and bucked her hips. Sam was spreading her with one hand, and twisting a butt plug that was buried deep in Mom's ass with the other. As she swabbed at Mom's pussy with her tongue, Sam's short hair and perky profile disappeared behind her enormous white bottom, which was angled towards the closet. I stared at her thick legs, the soles of her tiny feet and her butt cheeks opening and closing as she worked on Mom.

I reached down again for my dick. I wasn't sure what was going on, but I sure as heck wasn't about to waste such a golden opportunity. Meanwhile, Mom kept the conversation going.

"I'm gonna cum. I'm gonna cum in your mouth sweetie. You ready? Oh fuck, here it comes."

"Come on Aunt Liz," Sam moaned in between licks, "cum for me. Cum in my mouth." She bent forward, mashing her face into Mom's privates, and at the same time opening up her own ass to reveal fat, dripping lips topped by a swollen asshole.

I fumbled frantically to unbutton the flap on my PJ's, but had trouble in the dark. My Mom started to convulse, letting out a deep groan and pushing her pussy into Sam.

"Oooooh, fuuuuck..."

I kept fumbling, forgetting everything except the desperate need to get a hand on my dick and cum right along with my mother. Feeling around, I realized with horror that my PJ's were caught on something at the back of the closet. Foolishly, instead of carefully extricating myself, I just pulled as hard as I could.

"Don't stop," Mom panted, quaking as if electrocuted. "I'm still—still--don't stop--!" I tugged as hard as I could, and the pants came free.

For a moment, I thought everything was going to be all right. Just for a moment. Then I realized my momentum was too much, and I went hurtling forward, bursting through the closet doors and landing painfully on my side. I let out a little groan, just as my Mom finished her orgasm and opened her eyes.

To this day, I've never seen anyone get under covers quicker than Mom did when she saw me in that room. She clutched the comforter around her throat and shrieked as if I were a knife-wielding maniac. I think she would have kept shrieking forever if Sam didn't start laughing hysterically the second she saw me. As I laid perfectly still, hoping to somehow crawl back from whence I came, I could hear Mom reprimanding her.

"This isn't funny, Samantha! Matthew! What are you DOING IN HERE?!"

I glanced up, and met Sam's smiling eyes. She was under the covers next to Mom, stifling laughter, and her face and neck were tomato red.

"Hi cuz," she said between chuckles, "Happy birthday."

"Uh," I stammered, "I—I, uh--"

I rolled off of my side to try and stand up, without realizing that by doing this, I pointed my still erect penis straight at my Mother.

"Oh my God, Matt. What were you doing?"

Fishing for any sort of explanation, I blurted the first thing I could think of.

"Sorry, I thought Dad was in here."

Mom's face flushed red. "You thought what? What the fuck were you thinking?!"

"I thought...I...I didn't know Sam was..."

"Oh Jesus."

I had to shift the focus to something, anything else, so I said something I almost immediately regretted.

"Does Dad know you and Sam have sex?"

Mom stopped dead, as if all the wind had been knocked out of her. Her flat, brown hair settled around her collarbone, her tanned, motherly face sank, and her deep Cherokee eyes seemed to instantly fill with tears.

"Oh God. Oh Jesus Christ."

Luckily, Sam decided to stop laughing and try to help the situation.

"Oh, come on now," she said playfully, "this doesn't have to be a big deal."

"What are you talking about?!" mom screamed, "my son's seen me having an affair! With his cousin! It's a pretty big fucking deal!"

"Calm down, Aunt Liz. You're just making things worse."

Mom did calm down, but not by much. She just stared at me, looking totally unsure of what to do or say next. Which wasn't like her.

"Come over here, cuz," Sam said, "I know this is kind of weird, but we're going to talk it out."

Mom looked like she was about to protest, but she held her tongue as I sheepishly walked to the foot of the bed and sat down on the edge, acutely aware of being shirtless, and even more aware of my stiffy, which had gone down, but not by enough.

"No, I think you should go Matty," Mom said. "I'm very sorry about this, and I think you should go back to your room and we can just pretend it never happened. I promise you, this will never happen again. This isn't right. This—it's your birthday, for God's sake--"

"Don't talk like that," Sam interrupted, "you'll give him a complex."

"I've traumatized my son!"

"He doesn't look traumatized to me. Please, Aunt Liz, let's just talk."

I felt Sam's warm foot wiggle out from under the covers and rub against my back reassuringly.

"Matt," she said, "you're old enough to know about sex. Have you had sex yet?"

I had a flash of holding my sister's legs over her head and pumping her pussy with all of my might.

"Um...yeah," I said.

"Well, then you're old enough to know that sometimes, when I visit, your Mom and I like to have sex."

"Stop it, Sam!" Mom said.

"I think he's figured that much out himself," Sam countered. Mom looked about to speak again, but Sam went on.

"Your Dad doesn't know, but I think it's best that way. Aunt Liz and I love each other, and we're family, and...well, for one thing, that's a lot different than your Mom fucking around on your Dad. Don't you think?"

"Yeah," I said. I did.

"Good. We probably should tell your Dad, but...I guess we're both scared of what he might think, and we both thought that since we only get together like this once or twice a year, it wasn't a big enough deal to bother him with. And I know, that's kind of a bullshit excuse, and I can tell you we've talked about telling him a lot, but somehow, I guess we just never...got around to it. And that's wrong of us, and I for one am sorry about that."

She looked at Mom pointedly, and Mom barely croaked "sorry."

"Do you understand, Matt? Are you mad?"

I looked back at Sam. "I understand," I said. Sam grinned and opened her arms.

"Give me a hug, cuz! It's so good to see you!"

I glanced at Mom first, who looked on impassively, then inched up the bed to Sam and hugged her. Her arms were hot around my bare torso. To my surprise, as she released me and I leaned back, she started petting my chest, moving her right hand back and forth and lovingly stroking around my nipples. My nipples are sensitive, and I couldn't help but get a rush of adrenaline from the feel of my cousin's hand on them. My dick started to get throbbing hard again almost immediately.

"Now I don't think we need to ask what you were doing in the closet. I think the real question is what do we do now?" There was enough of a suggestive undertone in Sam's question to snap Mom back to reality.

"Sam, what are you doing?" Her voice was stony, reprimanding. Mom-mode.

"Look, Aunt Liz. Little Matty's gotten so big, hasn't he?"

Sam bent forward and opened her mouth, sucking on my nipple and licking all around it with her thick, ruby tongue. Her tongue was perfect, the most loving caress you could ever imagine.

"Sam, stop playing around," said Mom. "Please, you have to stop."

For me, this was uncharted territory. My sister the slut seducing me in a tent was one thing; fooling around with Sam when Mom looked like she was about to blow a fuse was another entirely. Was there a chance this could actually happen? Did I dare press my luck. For a moment, I silently grappled with the turn my life was about to take.

Sam stopped. "Does that feel good, Matt? Am I making you uncomfortable?"

"I'm very comfortable," I said noncommittally.

"Do you want to suck on mine?"

Now or never. I nodded, ever so slightly.

Without waiting for further encouragement, Sam lowered the covers, revealing her breasts like an artist unveiling a statue.

My cousin Samantha's breasts are more than in proportion with the rest of her body. In fact, for every pound of soft, pink flesh lending weight to her curves, there seem to be two or three pounds dedicated solely to her enormous bosom. They're the kind of breasts you can't help but stare at on family visits; heavy, deliciously round, and pressed together to form a plunging valley of cleavage on an epic scale. More than anything, Sam's breasts look soft and warm, like the welcoming pillows of a freshly made bed. I gaped at the wonderful sight of her double-D's, her short, fat nipples hard and resting on big pink areolae each at least two inches across. Slowly, I inclined my head and put my lips around one. I heard Mom hold her breath. Then I rolled Sam's stiff nipple around on my tongue and started sucking gently. At the same time, I reached up with a trembling hand and felt the weight of her other breast. Soft. The taste of her skin reminded me of Lisa. Sam hummed like a happy cherub.

Mom was wiggling under the covers, moving uncomfortably. It took me a moment to realize what she was doing--taking the butt plug out. All this time, she'd still had it inside her. She removed it, but kept it hidden under the covers, staring at us and breathing heavily. The blankets heaved with her breath as she became...aroused? Angrier? I knew at that moment that if things went right, the fantasy I'd had the second I first saw them from the closet could come true. After all, if she hadn't at least been tempted, she wouldn't have let things get this far. And I could tell by looking at her she was struggling with her desire to give in to Sam's way of thinking. But if thing's went wrong...

Suddenly, I felt Sam's hand tugging on my dick through my PJ pants. I immediately felt my balls start to swell and my hard-on stiffen even more.

"You know Aunt Liz," she said, "he's already seen me eat you out. There's not much more damage we can do."

"Sam, I..." Mom trailed off, but I glanced at her face and could see her staring intently at me while I suckled on Sam's tit. Just for her, I sucked in as much as I could, then let it pop out of my mouth and slid my tongue across her nipple. The whole time, I kept eye contact with Mom.

Sam kept gently stroking me through my PJ's. "Ooh," she said, "he's good too. Where'd you learn to suck on boobies so well, cuz?"

I knew I had to push things further. Either it would make Mom completely flip out, or it would lead to paradise. I had to risk it. "Lisa," I said.

Sam laughed. "I should have known! That little slut."

"Matt, are you serious?" Mom asked, inching away from us on the bed. "Is that true?"

I nodded. Not wanting to dwell on the subject, I asked Sam, "Will you take it out?" If I was going to force the issue, I figured I might as well go all the way.

"Well, I usually don't go for dicks as a rule, but I can't really say no to my favorite little cousin on his birthday, now can I?"

Sam pulled the waistband of my PJ's down, letting my stiffy finally spring free. After being cooped up in my PJs for so long, it felt great to let it bob in front of me. It stood almost eight inches, uncut, and was thicker than most. She touched it gingerly with delicate fingers, then started slowly tugging at it.

Mom stared. Her tongue darted out to moisten her lips; words failed her.

"Wow," said Sam, prodding. "Your own son's cock. You made this little baby, and now here he is all hard. Weird, huh?"

Mom couldn't take it anymore. She threw back the covers and strode across the room as if to leave. At the last second, she turned back and looked again at my cousin's hand pulling on my dick. Sam was alternating hands, running one down the length of me, then the other. So soft. I looked back at Mom, really seeing her completely naked for the first time. Her modest breasts hung above a slender, toned belly and a tangled patch of dark brown hair. I could see drops of moisture on her pubic hair, and her pussy lips were swollen. My dick responded.

"Ooh," Sam giggled, "It twitched. It must like you Aunt Liz."

"Did you really have sex with your sister, Matty?" Mom asked.

"Yes, Mom. But it's okay. I really liked it."

Sam butted in, hijacking that line of inquiry. "What do you think Aunt Liz, should I suck it?"

Without waiting for an answer, she shifted her body and brought her plump face down to the head of my cock. Her pouty red lips opened and that luscious tongue came out to meet my precum. She slid about four inches of my dick into her mouth and started massaging the shaft with her lips and tongue.

"Sam, stop it!" said Mom, although her tone was now far from authoritative.

Sam pushed me deep into her throat, bringing her lips almost down to my balls, then sucked my dick all the way up before pulling me out of her mouth. "Well," she said to Mom, "give me something else to suck on or I'm going to keep sucking Matty's dick."

Mom hesitated for a moment, then nimbly came back to the bed and flounced down next to Sam. To my delight, she didn't bother getting back under the covers. Sam immediately rolled over and kissed Mom deeply. Mom closed her eyes and stuck out her tongue and Sam started sucking on it greedily. After a few seconds of making out with Mom, Sam pulled back and got some air. Mom still looked unsure, to say the least.

"Now," Sam said, "I'm going to make this really easy for you, because I love you so much Aunt Liz. If you want to fuck your little son, the boy you gave birth to...just keep your eyes closed. You don't have to admit it, you don't have to say anything, just pretend you don't even hear me. If you want to suck your son's cock and let him fill you up with his spunk, you just keep those peepers shut."

She waited for a second. Mom's eyelids fluttered, fluttered, then settled, firmly closed. She took a sharp breath and held it. I could see her whole body trembling. "Okay," Sam whispered. "Here we go." With one arm, she pushed my head towards my mom's breasts.

"There you go cuz," she said, "suck on her just like when you were a baby."

Mom's breasts were smaller and rounder than Sam's, and her nipples were soft and brown. I took one into my mouth and felt mom shudder.

"Suck them like you're feeding." Sam reached down to the smooth crevasse of her shaved pussy and started to massage herself. I kept sucking Mom's nipple and she began to quietly whimper.

"Fuck," said Sam, her voice instantly turning from sugar and sweetness to husky, "Liz he's sucking your fucking tits. God, I can't believe this. Fuck." She started rubbing her clit madly. "Kiss your Mom, Matty. Put your tongue in her mouth."

 Mom kept her eyes closed, but hummed with joy at the mere suggestion. I sloppily pulled her nipple from my mouth and moved up on the bed until Mom and I were face to face.

"Open your mouth," I whispered. She opened it slightly and leaned her head back, inhaling sharply. I brought the tip of my tongue out and slowly licked her lips, then slid inside of her mouth. She responded with a passionate kiss; her mouth tasted wonderful and familiar. Suddenly I felt her soft hand wrap around my cock. For the first time since she got back on the bed, her eyes opened. They looked directly into mine, fierce, commanding, and at the same time on the verge of losing control.

Smiling, she said "No one tells Dad about this, ever."

Then she rolled me onto my back and moved down on the bed, hunching over my hard dick as if worshiping it. Her eyes fixed on the gleaming tip, she wrapped her hand around the shaft and squeezed hard. I arched my back, bringing myself within inches of her face. She met me in the middle, lips parting to admit me into the close humidity of her mouth. Her lips pressed together around the head of my penis, then slid downward to make way for her tongue, which she swirled around me. She enveloped me. My dick felt hot, wet, and tightly compressed.

"Mom, that feels so good," I said.

She pulled the root of my dick towards her mouth, hard, stuffing as much of me as she could take into her. She sucked hard, desperately, as if trying to get all of my cum out of merely by the force of her suction. I could see rivulets of spit drip down the shaft as her lips stretched to fit around more and more of me. Suddenly, I could feel the head of my dick hit the back of Mom's throat. Next to us, Sam spread her pussy wide open and slipped two fingers inside of herself.

"Fuck, suck that dick Aunt Liz, take the whole thing."

Mom pulled me out of her mouth and jacked me fast as she looked into my eyes. I was slick with her saliva, and she slipped one hand up and down with ease while she squeezed my balls with the other. She spoke as if she were admitting all of her deepest secrets, things she had never thought she'd be able to say, to anyone. They came pouring out, uncontrolled and unfiltered.

"I'm going to put you inside of me now Matty. I'm going to put your whole body in my mouth. I'm going to swallow you up and gag and choke on your cock and swallow and swallow until you're all the way inside me. I want you so bad, baby. I do. Oh, God, I want your dick. I want your cum. I want to feel my son's hard cock exploding right in the middle of me. I want to choke on it. I want to be so full of you, Matt. I want my little baby boy to fuck my throat deep and hard. Fuck Mommy's throat baby."

"Do it Mom." I said, wiggling my hips with impatience, "suck it now. I can't wait any more. Please, do it. Fuck. Fuck." I raised my hips, pushing my stiffness towards her moist lips. I seemed to get harder and longer, as if my penis were reaching out, begging to be swallowed.

She slipped me wetly back into her mouth, working her soft lips around the head and opening her throat to fit me all the way in. She pushed hard and all at once; I felt myself go past the back of her tongue and down her throat. She was actually swallowing me, swallowing me whole. This was beyond anything I had ever experienced. Her nose flattened against my stomach as I gasped with pleasure. She gagged and swallowed, her throat closing and convulsing around the whole length of my cock. And the sounds! The suck of air as my dick pulled an inch out of her throat and then thrust back in. The frenzied slurps as she vainly tried to catch the slobber that she left dripping down my balls. It was too much to take. I grabbed her head and forced her down as far as she could possibly go.

"Mommeeeeeeeeee.'

I was all the way inside; my Mom's tongue was running along the underside of my balls while my cock filled her throat entirely. She made strangled choking noises even as she pushed herself down onto me again. I started bucking, fucking Mom's throat. I had my eyes screwed shut, and had forgotten everything except the feel of that clenching around my aching dick, when Sam leaned against me. I could feel her big arm still pumping away at her clit.

"Matt," she said, "can I sit on your face? Will you eat me out? Please, this is too fucking hot."

"Oh, God yes" I moaned, "I want to taste your pussy, Sam."

Sam turned to face the headboard, away from Mom, who was now bobbing up and down on my pounding dick.

"Here I come, cousin," she said, and squatted over my face, firmly pulling her big ass cheeks apart. Her juicy pussy lips and rosebud asshole filled my vision, and then the rest of my senses as I opened my mouth and took her wet slit against my tongue. My face was buried in a mountain of creamy flesh. Her soft butt rocked against me and we sank into the bed together, all warmth and taste. Scooting forward, she brought her asshole to my mouth and I didn't waste a second jamming my tongue inside as far as I could. Sam moaned and laughed at the same time.

My heart was going a mile a minute. I felt like an electrical storm was crossing every wire in my body. I forced myself to focus on the reality of what was happening, the thought that I was actually fucking my own Mom, and gorging on my Cousin's asshole, on the morning of my eighteenth birthday. The longer I held the incestuous thought in my head, the more I could feel my orgasm building inside of me.

Sam ground her asshole down onto my tongue, then rocked her hips to give me access to her pussy and clit, then shoved back again. "Oh, fuck," she moaned, "eat my ass cuz. Fucking eat it."

She played with her clit and pressed against me while I pushed myself in and out of her rosy butthole, sucking at her and trying to work my face deeper between her cheeks. Whenever she bounced up off of my face, I got a glimpse of Mom, sucking my dick into her mouth again and again. She was in a kneeling position now, bent forward with her big brown tits drooping onto my thighs while she sucked. I could feel her nipples against the skin on my legs, and my eye traced the curve of her spine up to her curvy rump, wiggling in the air while she blew me. Blew her son.

That thought did it. I felt my balls clench. Gasping for air and lifting Sam's butt, I managed to squeak out:

"I'm going to—to—"

Sam pushed back down onto my face, cutting off the rest of my sentence. But she got the drift.

"Do it, Matt. Give Liz your jizz." She giggled again.

As I started to come, my back arched, burying me, almost smothering me in Sam's big ass and dripping cunt. She shook her head with pleasure and beamed over her shoulder at Mom. "Shoot it deep, cuz!"

The first volley of cum shot out of me, and Mom grunted as she gulped it down. She pushed her lips to the base of my cock and swallowed. I felt the sliminess of my spunk around my cock as another load hit the back of her closing throat. She kept her head down, her mouth fused to the base of my cock, as I let out a low cry and shot again and again. Cum filled her mouth completely; a pearly drop squeezed out between her lips. Her cheeks were full of my cum, and I knew I'd already shot plenty down her throat.

Mom gagged, then grunted again, then I could feel her start to swallow.

"Come on Aunt Liz, drink it. Drink your baby's cum." Sam was staring at Mom's cum-dripping lips and her hand was a blur at the top of her pussy. Mom kept trying to eat it all, slowly pulling me out centimeter by centimeter to give her room to swallow. She was careful not to let any more drip out. Sam's voice became broken and I could feel her start to shake as she got close to her own orgasm.

"Man up bitch! Eat it all. Eat that cum. You got it. Fucking swallow Aunt Liz. Swallow Matty's spunk."

Sam jammed her ass back onto my face and I laid my tongue against it, running it along the length of her cunt.

"Oh FUCK!" she moaned "Oh God oh God oh God Matteeeeee, don't stop! Don't fucking stop! Keep eating meeeeeeee--!"

Sam's body rocked so violently I thought she was going to fall off the bead. She let out a high-pitched squeal and shook and shook while Mom's throat closed again and again around my jerking stiffy, draining away the cum until she was once again suckling me with Motherly love and affection.

Sam tensed for a second, seemed to suffer a minor aftershock, then started to giggle, trembling as she eased onto all fours and off of my grinning face. Her cheeks were flushed, and sweat plastered her blonde hair to her forehead.

"I am SO glad you caught us!" she said. Mom just said "mmm," and nibbled lightly at the top of my cock. She was holding it in both hands now, gently, and fawning over it like a pet. Her tongue softly reached out and licked up the one stray drop of cum.

"That was..." I sighed. Mom seemed to be able to stop looking at my dick for the first time since she started sucking it. She kept stroking it idly as she looked at me with sparkling eyes.

"Did you like that, Matt?"

"Of course he liked it!" said Sam, "who doesn't like getting off?"

"I did, Mom. I really did."

Sam took us both in with a stern frown. "What's with all the past tense?" she said. "This is an ongoing concern, kittens."

"I think I might need a minute," I said. My dick was just beginning to soften in Mom's hands as she massaged it. She took one hand away and stoked my belly, like she used to do when I had trouble sleeping. I was in heaven.

"Men," Sam snorted. "You always think it's over just because you came. Lesson one, cuz: you be a gentleman and eat your Mom out this instant."

I looked at Mom questioningly. She smiled and put a hand between her legs, caressing herself. "I'm so wet, baby," she said. As I sat up to kiss Mom, Sam wrapped herself around me from behind, pressing her giant chest against my bare back and encircling me with two chubby arms. Mom smoothly passed my cock to Sam's soft and waiting grip, then sat up to bring her face close to mine. I could feel Sam's chin on my shoulder, and hear her breath as she whispered into my ear.

"Kiss her."

I reached out and pulled Mom to my mouth. Our lips touched, then parted, and the taste of my own cum mixed with Mom's tongue filled me. We made out ravenously, our tongues entertaining and writhing against one another. Sam started to lick my earlobe, then slipped her tongue inside my ear as she drew her fingertips across the underside of my balls. I ran my hands down Mom's back and she moaned, sucking on my tongue as I stuck it deep into her.

The sounds of us kissing, and sucking, and slurping, filled the room. I could hear Sam's tongue inside my ear, and her hot breath getting faster and shallower. He body was so warm and soft against me. I sucked Mom's tongue in and out of my mouth and she hummed quietly, gently bringing her hands to my face.

"Lick me, baby." She hugged my face to her chest and drove my head downward. As Sam disentangled from me, I stuck my tongue out and enjoyed the slow ride down Mom's body, between her breasts, down her stomach to her belly button, to the soft mound above her pussy, to the fine hairs just above, and finally to the sweet salty taste of the juice of her swollen self. Her lips were plump and glistening; I sucked one into my mouth and massaged it with my tongue.

"He's so good, Sam." Mom shuddered.

"Try not to upstage me, Matty," Sam laughed, then backed up and got on all fours behind me. "Here, birthday boy, get that little butt of yours in the air and I'll try and provide some distraction."

I moved to the other side of Mom's pussy, sucking as much of her flesh into my mouth as I could, and simultaneously inching my knees back until I was in a bowing position with my ass in the air and my head buried in Mom's crotch. My dick hung straight down between my legs, still soft, and Sam tugged it playfully. "I got you a gift certificate too, but I'm going to go ahead and call this my real birthday present."

Then she popped my balls into her mouth and sucked them lightly. I moaned, and started to lick up and down Mom's pussy. Her juices were already covering my mouth and chin. "Oh God, Sam," she said, "eat his ass. Eat baby Matty's asshole." She sat back on her elbows and ground herself into my face. Sam's wide tongue cradled my balls for a moment, then drifted upwards and started to run the length of my buttcrack. It sent a shiver up my spine, through my tongue and into Mom's swollen clit. I pressed her clit with my tongue and started moving it back and forth in the way Lisa taught me. To my satisfaction, Mom moaned in extacy. To my even greater satisfaction, Sam started circling the tip of her tongue around my butthole.

"Oh shit, I'm going to come quick," Mom panted, and pressed me into her. "Stick a finger in me, baby." I slipped an index finger into her and crooked it, probing for her G-spot. "Oh God, that's it. Oh fuck. Did Lisa teach you that baby?"

I nodded, sucking at her pussy and jamming my finger in even deeper. As I did, Sam spread my ass cheeks with her hand and buried herself in my butt. I could feel her nose mash against me and her tongue forcing its way through the tight opening. "Oh yeah," Mom said, "she taught you so good Matty. Your big sister taught you so good." As I kept eating her, she started to talk continuously, her eyes rolling into the back of her head in sheer bliss.

"Oh God, that's it. Right there, baby. Fuck she taught you good. My little girl taught my baby boy how to eat pussy so good. She taught him how to fingerfuck his Mommy so good. Fuck. Keep going Matty. Right there. I want to come in the same mouth my daughter came in. I want my little baby to make me cum. FUCK."

She grabbed me by the back of my head and forced me into her, lifting her butt off the bed at the same time. It was a challenge to stay on target, but I gave it my all, moving my tongue fast over her clit and hammering at her G-spot with my finger. Juice poured out of her and dripped down my hand as Sam fucked my ass with her tongue. Mom's breath started coming in short pants, and her voice went up an octave.

"Your big sister is a slut and so is Mama baby. Mama wants you to make her cum, baby, just like you made Lisa cum. Eat her pussy while Sam eats your fucking ass. Eat her fucking cunt while your cousin tounge-fucks your fucking asshole."

Sam moaned in confirmation, and started tugging at my dick as she probed the inside of my butt with her warm wet tongue.

"Eat my baby's ass, Sam," Mom said, "eat his ass out good and deep. Taste your cousin's asshole. I want you to taste my little baby's asshole. You make him feel so good. You have to make my baby son feel so fucking good, and get your tongue so fucking deep in his ass."

I stuck a second finger into Mom, pulling hard at her G-spot, and her attention snapped back to her pussy.

"Oh, GOD yes. Eat me Matty. Eat the pussy you came out of, Matty, eat the--oh shit. Oh shit, I'm going to come Matty. I'm going to commmmmme on my son's faaaaaace. Oh Gooood, oh Fuuuuuuck. Eat me Matty, eat me Matty, eat me baby, eat me baby, eat Mommy, eat Mommy, eat Mommy, EAT MEEEEEEEE--"

She bucked, her pussy pulsing around my fingers, and screamed.

"OH FUUUUUUCK I'M COMMMIIIIIINNNNNGGGGGG!"

She held me firmly in place and humped against my mouth and probing finger.

"FUUUUUCK! KEEP GOIIIIIINNNNNGGG!" She bucked and shook, my tongue slashing at her and my finger pulling firmly inside her pussy. Sam joined the chorus, moaning loudly from behind me. Mom convulsed, but I kept licking her hard and fast. "Oh God, Matteeeee--" I sucked her clit into my mouth and began to slowly swab it with my tongue.

"Oh God. Oh shit. Oh God."

Mom trembled, let her bottom hit the comforter, and lay still, heaving breath. Sam left my asshole with one last lick down the length of my taint, balls and cock, which was already showing signs of reviving. There was a moment of silence as Mom struggled to recover.

"Fuck yeah!" Sam said. "That was so hot Aunt Liz. Good job Matt."

"Thanks."

"Your boy's a fucking superstar, Aunt Liz," Sam continued, but Mom was temporarily beyond hearing. "And his ass tastes good, too."

"Mm-hmm," Mom managed.

Sam gave me a big hug and kissed me, exploring my mouth with her tongue. "Mmmm," she said, "you taste good too Aunt Liz."

"She sure does," I agreed.

"Well," Sam said, "I think that's enough foreplay. I want to see Liz get fucked."

Mom finally seemed to come back into the room. "What?"

"That's what you straight people do, right? Let's see some Mom-on-son deep dicking."

Mom looked at me, then back at Sam.

"I don't know..."

"Well I do. I didn't talk you into committing incest with your son just to watch you suck each other off. I want some action here."

That time I laughed. Mom stared at me with wide eyes.

"But...that's...different. It's too dangerous. I don't even have any condoms in the house."

That was true. Dad had gotten a vasectomy after I'd been born (a fact he constantly reminded me of when I misbehaved in his eyes), and I'd never seen him wearing a condom when I spied from the closet. Sam hummed disapprovingly and ran her fingers through my hair.

"Look at him, Liz. Don't you want to feel this inside of you?" I decided to remain impartial. I wanted to fuck Mom, but I wasn't about to push it.

"I...it doesn't matter. I could get pregnant, or--"

"So we'll worry about that later."

"Sam!" Mom barked, "that's incredibly irresponsible! What is Matt supposed to think when you say that? What kind of example--"

"You know some people," Sam interrupted, "would call going down on your son at all, or your niece for that matter, a less-than-stellar example of responsibility and restraint."

That silenced Mom. She looked me up and down again, then shook her head resolutely. "No," she said, "I can't. I'm sorry, but I can't."

Sam grinned. "Of course you can't. We've gotta get him hard again first."

With that she yanked me towards the edge fo the bed and hopped off herself, kneeling in front of my half-mast. Mom frowned.

"That's not what I--"

"Come on, Liz," Sam said, "let's show him how to share, set a good example." Without saying anything, I swung my legs off of the bed so I was sitting on the edge, Sam positioned between my thighs. At some point she'd put her hair up with a tie, and the tight bun bobbed as she stuffed my softness into her mouth. I could feel myself getting hard inside of her. I flexed my toes with pleasure and laid my hands on her shoulders as she settled her butt down onto her calves.

"That feels great Samantha," I said. I gave her shoulders a squeeze and began to brush her neck with my fingertips.

She smiled up at me around my cock, then her eyes darted to Mom on the bed.Mom rolled her eyes. "I don't know where you kids find the energy," she grumbled, and stood to come over. Her pussy still dripped down her legs, and I stared at the wet streaks on her brown thighs as she came and knelt beside Samantha. I had to open my legs wider to accommodate her.

"This doesn't mean I agree to fuck you," she said, then kissed my knee and smiled at me. "It just means I love the way you taste." She laid her head against my thigh, resting her hair against me while she licked at my shaft and Sam kept sucking hard on the tip. I pet her head sweetly.

"I love you, Mom."

"I love you, baby," she said. "And as soon as I get your sister alone, I'm going to love her, too." Sam caught my eye and winked, at the same time pushing my dick against the inside of her cheek. Mom lowered her head and started sucking on one of my balls. She would suck it lightly, let it pop out of her mouth, then wrap her lips around the other one and repeat the process. The whole time, she kept sticking her tongue out and pressing it against the skin underneath my scrotum. Sam's bun started bobbing more fervently as she wolfed my cock down. She didn't take me as deep as Mom had, but her mouth was softer and warmer, and she left plenty of room for Mom to occasionally lick or suck at the base.

"Wow, for a lesbian you're really good at this," I said. Sam laughed around my prick.

"That's nothing, smart-ass," she said. "Here Aunt Liz, take your son's cock for a minute." She handed me over to Mom's capable hands, and I could instantly see Mom's regained composure starting to crumble. It was like a possession; the look of wild, uncontrolled desire was creeping back into her eyes. I could tell she was trying to fight it, suckling on my dick and stroking me slowly with one hand. Her nipples were hard as rocks, and her stomach tensed as she bounced up and down on me. I couldn't believe it. She was actually struggling not to ram her head down and choke on my cock.

Meanwhile, Sam was pressing her boobs together, which was quite a feat with only two hands. She lifted one and sucked the nipple, then popped it out of her mouth and started kneading them together.

"You know," she said, "even as a kid, you used to stare at my tits. You thought I didn't notice, but I did."

"They're hard to miss," I admitted, "even as a kid."

"Mmm-hmm," she said, and spit down her cleavage, rubbing her tits against one another and pinching the nipples between two fingers. "It's natural. I didn't think anything weird or anything. I always wondered if you ever thought of me when you beat off though." She spit again. Her breasts were becoming slick with spit as she kneaded and squeezed them.

"All the time," I said, and shifted forward. Mom inched my cock deeper into her mouth.

"Ha! I thought so," Sam said. "I hoped so. Makes me feel better about thinking of your little cock and pink nipples whenever I used my vibrator."

She leaned forward again, and rose into a kneeling position, letting her tits hang off of her body. Mom grudgingly slipped my penis out of her mouth and moved aside as Sam lifted her tits towards it.

"Did you ever think of this, cuz?" She pressed her slick boobs against each other with my cock in the middle, and began slowly moving them up and down. She pushed them together tightly, making the perfect sleeve for my aching dick. I suddenly realized I was completely hard again, and began pushing my dick in and out of Sam's tits. The head of my cock appeared and disappeared in between her deep cleavage, and with every thrust I could see her big nipples rub against each other around my hard shaft.

"All the fucking time," I said again, grinning. "But it feels even better in real life."

Sam stared into my eyes with a nasty expression and gracefully kneaded herself around my thrusting. As she squeezed her tits together and pulled me through, pre-cum bubbled out the tip of my cock and joined the rest of the moisture of her slick bosom. "Fuck yeah it does," she said, and increased her speed. I could hear her boobs slapping against my thighs with each thrust. Mom poked her head in and expertly sucked at the tip of my dick every time I pushed through Sam's boobs.

"There you go, Liz, get it," Sam said, "Get that fucking dick."

I fucked Sam's tits faster; her knuckles were white as she squeezed herself together. "Kiss it, Mom," I said, "Get it in your mouth." I pushed through harder, pulling back my foreskin, and my gleaming cockhead peeked through between Sam's swollen nipples. Mom obediently lowered her head onto me and started sucking and lapping at my pre-cum.

"Oh God, Mom, that's good," I moaned.

"You're so fucking hard, Matty," she replied, greedily consuming the head of my penis. Sam jerked her tits up and down my shaft; I stared at their soft changing shapes as they flattened against my thighs, then wrapped around my cock again and again, enveloping me then releasing me, bulging between Sam's petite fingers, nipples rubbing against one another and against Mom's lips as she took me into her mouth.

"Hard enough to fuck yet?" Sam asked me. I nodded vigorously, but Mom looked at her with a frown.

"I told you--"

"Not you, Aunt Liz. It's been a long time since I've gotten a dick to play with, and I don't intend to waste it."

Sam slipped her tits off the top of my dick and started to climb back up onto the bed next to me.

"What do you say cuz? Think you can convert me?"

Sam got on all fours on the bed, and grinned back at me over her shoulder. Her face was flushed, plump, and dimpled. Her whole body seemed to be made of soft curves and dimples. It looked like there wasn't a square inch of her that wasn't blushing except for the white soles of her feet. Red was even beginning to creep down the masses of her hanging breasts, and filling her shaved pussy lips. Bits of her hair had escaped the bun, and strands fell every which way over her grinning, chubby, angelic face.

"I'll give it a shot," I said, and turned to take up a position behind her.

"Matt--," Mom started, but Sam was having none of it.

"We want to get nasty Auntie Liz, so you can either leave or come keep me company at the front."

Mom licked her lips, and seemed to accept the situation. "In a minute," she said, "I want to watch him go in."

"You heard her, Matty. This ass is all yours." She wiggled her rear back and forth and arched her back, spreading her ass open. "Why don't you slide that in nice and slow while your Mom watches?"

I inched forward, maneuvering my cock towards her pussy with two fingers. Mom's eyes were locked on the point of my dick, and she watched with rapt attention as I touched the tip to Sam's wet slit. Sam held her butt perfectly still and high in the air as I slowly pushed past her lips and felt around for her opening.

"Getting a good view, Aunt Liz?" Sam asked.

"Fuck yes, and it looks like it feels good."

"Oh, it does, Mom," I said, sliding the first inch of my dick into Sam's pussy. She was slick, but so tight it was slow going. As I pushed forward, my dick bent a little with the effort. Not wasting a second, Mom leaned in and spit on Sam's asshole, letting the lubricant run down her crack and onto the shaft of my cock.

"There you go baby."

"Thanks Mom," I said, pushing in even further.

"You think you can go all the way in, Matty?" I could see she was playing with herself.

"She's really tight, Mama."

"Don't blame me!" Sam joked. "You're just too--oof--big."

"Well," Mom said, stroking my back with her free hand, "Samantha's a big girl, and she can take it, so you just go ahead and push for Mommy, okay?"

"Okay Mom," I said. I leaned over Sam's body to get better leverage and gave a long, slow, hard, push. Sam's reluctant pussy tightened around my cock but gave way inch by inch. "OooooooooOOOH!" Sam moaned as my balls pressed up against her fat ass.

"Oh Mom, fuck. It feels so good in Sam's pussy."

"You like that tight hole, baby? You like your cousin's tight little snatch?"

"Oh yeah, yeah, yeah" I said, sliding back out and throwing myself into her again. "Fuck, she's so fucking tight."

"Aunt Liz, his dick is so good." Sam yelled back. "Matty's big dick is so fucking goooood." I pushed in all the way again, and Sam winced. "Oh, FUCK, but it's been a while since I had a dick in me. Liz, come help me cope with the pain."

Mom hesitated, but did as she was told, getting on all fours and taking up a position next to Sam. That put her ass right next to me, and I stared at it as I kept slowly loosening Sam's pussy. Her ankles and feet looked small and dark next to Sam's broad white ones. I rested a hand on her butt, and she jumped, looking back at me.

"Look at him, Liz, he's fucking nuts about you."

"You like my ass, Matty?" Mom asked. "It's not too old?"

"Not at all, Mom," I said. "You're whole body is incredible."

Sam reached out and yanked Mom's face towards her, slipping her thick tongue between Mom's lips. I took the opportunity to thrust again, and Sam sqeauked through the kiss. "Aunt Liz, you have GOT to try this thing," she said, and smiled back at me. I took a handful of each of Sam's ass cheeks and started a quick pumping rhythm. Her body moved with mine, her butt cheeks opening when she pushed back and closing around my cock when we lurched forward again. Mom kept kissing Sam deeply and moved to keep up with her. Her ass too was opening and closing as she rocked back on her heels. I could smeel her scent rising from her open pussy and tight asshole.

"Is it good Sam? You like my son's cock inside you?"

"Oh fuck yes Aunt Liz."

I kept fucking Sam, but moved one of my hands to Mom's ass and started to squeeze her cheeks. She didn't seem to mind, so I slid my hand lower as she kept talking dirty between kisses.

"You like the feel of his dick in you without a condom?"

"Yes, Ma'am."

"You like Matty riding you bareback?"

"Oh God yes."

"You like fucking your cousin, Sam? You want him to come inside your pussy?"

Sam grunted and shifted into a higher gear. "Oh fuck yes! I want Matty's come in me! I want him to come in me!"

Mom stuck a thumb into Sam's mouth and Sam sucked on it voraciously.

"What if you get pregnant?"

"Fine by me!" Sam yelled, "I love my little cousin Matty and I want him to fill me up with his cum!"

As Sam went on talking, Mom's eyes grew wider and wider. I slid my hand further down the length of her ass crack, and my fingertips found the heat of her pussy hole. "And if I get pregnant," Sam said, "and it's a little girl, I'll teach her to suck on uncle Matty's dick whenever he wants. I'll teach her to drink up her uncle Matty's cum and take his dick in every hole whenever he wants it. HARDER, Matt! Fuck me HARD!"

I jammed a finger deep into Mom's pussy and pushed into Sam at the same time. Mom moaned and Sam started wildly humping her pussy against my cock.

"And if it's a little boy?" Mom asked, spreading her legs to let me fingerfuck her deeper.

"If it's a little boy," Sam groaned, "I'll still teach him to suck Matty's cum, and to eat me out, and to take my cousin's fat dick up his tiny little asshole. I'll teach our baby to milk his Daddy's cum out with his tight little butt. And while he's doing it I'll suck on his little pecker and swallow all of his spunk! I'll turn our little baby into a slut for his mommy and daddy to suck and fuck every night!"

"Oh FUCK," Mom shouted, "fingerfuck me Matty, finger fuck me HARD."

"Because I'm a fat slut," Sam went on. "I'm a big fat slut who loves to get fucked by her baby cousin!"

My cock rocketed in and out of Sam's dripping pussy, and Mom squirmed on my fingers. She was so lost in her fantasy, I knew there was nothing she wouldn't do. Which is exactly why I pulled out of Sam and lined myself up behind Mom's ass. She didn't even notice what I was doing until she felt me try to slip my dick into her without removing my fingers. When she made the realization, she immediately opened her eyes, caught her breath, and glared back at me.

"Matt!"

"Shh, Mom. Keep talking to Sam. I'm going to go inside of you now, and you're not going to stop me."

I'd never given my Mom a command before. My cock ached at the scandal of it. And it looked like Mom was about to protest.

"Just close your eyes again, Aunt Liz," said Sam. "Just close your eyes and--"

"NO." I said, holding the quivering tip of my dick at mom's entrance. I could feel her heat and moisture on my tip. I grabbed her by the hips and held her in place, hard. "No, it's not going to be that easy this time. You can't close your eyes, and you have to say it."

Mom whimpered and pulled forward, but I held her hips in place and slapped my dick against her wet cunny. I began to slowly move the length of my cock along the length of her pussy, never going in, but sliding against her clit.

"Say you want me to go in you, Mom."

Mom just moaned.

"Say it, Aunt Liz." Sam kissed her.

"I...fuck me. Matt."

"Please," I commanded.

"Please," she said. Her whole body was trembling in my hands.

"Please what?" I pushed.

"Please put your dick in me, baby. Please fuck me. I...I want you to. I want you to go in me. I want to feel your dick moving inside of me."

"This is so fucking hot," Sam said, stroking Mom's hair. Mom stared through her.

"Go on, Mom. Say it."

"Please, Matty! Please! I said it! Fuck me! Fuck me so hard!" She pushed her ass back, but I pulled away. I was getting harder and harder hearing her beg, and I wasn't about to put it to a stop so soon. Mom responded by turning her voice into a shrill whine, like a child begging for candy. Tears stood our in her eyes.

"Ohhhh, Matteeee, please put it in me! Fuck your poor old Mommy. Push your cock into the pussy you came out of! Push your cock into me and ride Mommy until she cums around you. Please, baby! Please fuck me!"

With one swift motion, I slammed my cock all the way into her. She screamed so loud the room overflowed with it, but she didn't pull away. Instead, she pushed herself back into me as hard as she could.

"FUCK! Fuck meeeee! Fuck me baby! Fuck me Matty! Fuck your Mommeeeeee! Ride me hard!"

I pushed in and out of Mom's pussy, fucking her so hard she had to brace herself against the headboard.

"Oh fuck Mommy, you feel so good!"

Mom was sweating and grunting with every deep thrust of my cock.

"It's all for you baby. Mommy's pussy is here to soak up your cum and make you feel soooo goooood." I leaned forward, grabbing Mom's tits and giving them a rough squeeze while my dick angled towards her G-spot. Her toes curled and she clutched at the soaking comforter.

"Oh God, why didn't we do this sooner?!" She screamed. "Never stop fucking me Matty. You've got to fuck Mama every night with your cock and explode with cum inside her!"

"I will, Mama," I said.

"Promise me baby!" she screamed.

"I promise to fuck you every night Mommy!" I shouted, ramming her from behind. "I promise I promise I promise!"

"You've got to fuck me every morning when Daddy leaves and again before he gets home. You've got to shoot your cum in me and let me suck it out of you every night before you go to sleep. Mommy wants you to keep her all full of your cum!"

I yanked Mom by the hair and she arched her back, working her ass on my stiffy. Sam was laying on her back now, watching us with several fingers buried in her pussy and sucking her own tits.

"Mommeee, I'm going to cummm—" I said. Immediately, Sam rolled over and pushed Mom and I apart. My dick slipped out of her and bobbed up, splattering Mom's ass with her own juices. I could feel myself teetering on the edge of orgasm.

"Not so fast, cowboy," Sam said, and laid back down. Mom whipped around to glare at her.

"What the—"

"Hey, you already got a load Aunt Liz," Sam said. She grabbed her legs and pulled them back towards her head, tightening her ass and opening her pussy up. Her giant tits looked even bigger squeezed between her thighs. "Besides, you didn't want to fuck him in the first place."

Mom stammered. "I—I—"

"Come on," Sam pleaded, "I'm company. You get him all the time."

"Can I please fuck someone?" I asked, impatient about the load held at bay.

Mom smiled. "Okay, just for a little bit. Fuck your cousin, Matt."

Without wasting a second I hopped over to Sam and buried myself in her now-familiar pussy. She squealed in delight. In this position, I could see the intense pleasure playing across her face; I must have looked almost exactly the same. I grabbed her by the ankles and pushed them back over her head, fucking her hard and deep. My balls squished against her swollen, dripping lips.

"Happy—fuck—birthday—shit—cuz—" She panted, and I leaned forward for a kiss. My tongue filled her mouth and my cock filled her body. I felt like we were one person, or as if she had enveloped me entirely. I closed my eyes and focused on the slowly building tension in my balls.

"Fuck. Fuck. Fuck." Sam kept up a continuous chant. Mom looked at my dick going in and out of her niece with jealous hunger and clutched herself. Desperately, she threw herself towards Sam and started sucking on her toes, then licking her foot and down her legs. She squeezed Sam's fat ass, then slapped it and squeezed mine.

Sam broke our kiss long enough to say "keep fucking me like that and I'm going to cum, cuz." Then she sucked my tongue into her mouth.

I could feel Mom wiggle a fingernail down my ass and play with my butthole. I focused on hitting Sam in the same spot again and again, and holding my cum back until Sam was ready to blow.

"Fuck Matty," Mom said, "she's going to fucking cum. Make Samantha cum around your cock."

"Fuck. Fuck. FUUUUUCK!" Sam wailed, opening her eyes wide and pulling her legs back even more. Her pussy tightened around me and I rammed her G-spot with my cock. "Oh God, here I cummmmmm!" Sam shook like an earthquake. Her pussy clenched around my dick like a fist, and it was a struggle to keep moving in and out of her. I pushed harder, and she wailed louder.

"I'm cummmmmiiiiiiiiinnnnggggg!" I shoved myself into her protesting pussy and felt more of her juices flooding her and leaking out onto the bed. "Oh God fucking God Jesus CHRIST FUCK ME MATTY!" She jerked her body back and forth, encouraging me to fuck her through her orgasm. As her pussy clamped onto me again, I could feel myself getting ready to blow too.

"Can I cum inside you Sam?"

"Cum in your Mom Matty. Blow your load inside Aunt Liz."

Mom looked as if she'd won the lotto. She was face down with her ass up before I could even pull out of Sam. She positioned herself at the edge of the bed, with her feet on the ground, so I hopped off and stood behind her.

"Come on baby," she purred, "give Mama your hot fucking load."

I moved towards Mom's inviting pussy. But before I could get inside, Sam was on top of Mom, pinning her immobile to the bed.

"What—" I started to ask, but was interrupted by Mom's muffled shouts. Sam was sitting on Mom's head, pushing her face into the bed with her ass and pinioning her arms at her sides.

"Cum in her ass, Matty."

I could hear Mom try and say something, but couldn't make it out. Sam yelled to her. "I hope that butt plug did its job Aunt Liz because you're about to get a big fucking dick up your ass." She grinned at me. "Do it cuz."

"Mom? Should I?"

"Do it Matt," Sam repeated. "She wants your load; give it to her in her fucking asshole. Do it quick."

I spread Mom's ass cheeks apart. I could see she was struggling against Sam's weight because her butthole winked and tensed. I held her cheeks open with one hand and put my cock against her with the other. I could already see it wasn't even close to fitting.

"Watch out Aunt Liz," Sam yelled, "here comes the airplane!"

I pushed the tip of my dick in. It was a tighter fit than Lisa had ever been, and I almost shot right then and there. It didn't help that as Mom screamed and squirmed, her ass kept milking my cock.

"Oh fuck, Mama, stay still. I've got to—" With a grunt, I pushed in another half inch. The tight ring of her asshole moved up my cock, and I could feel the warm sticky interior of her butt. "Fuck, Mom, your ass—so fucking good."

"In and out Matty," said Liz. "Loosen this bitch up before you blow your load in her fucking ass." Mom seemed to stop struggling somewhat, and her asshole relaxed a bit. I managed to go in another inch and a half. Mom moaned from under Sam's ass and wiggled her hips. I eased my cock out a bit, feeling her clench on me, and then pushed it further in.

"He's picking up steam, Liz," Sam said. "He's going to get all the way in. Aren't you Matty?"

"Uh huh," I said, pushing again, "I'm going to get deep in your ass before I shoot Mom. Can you take me all the way in?" I was already pushing again before she answered, not that I could hear what she said anyway.

"She says yes please," Sam giggled, and spit on Mom's asshole. I could she she'd let go of Mom's arms, and was now kneading her ass cheeks and spreading them for my invading cock. With every centimeter, I watched Mom's tight brown asshole stretch wider and wider to take in the base of my cock. I was almost done; my balls were brushing against Mom's hot ass.

"I'm going all the way in Mom," I said. "Hold on. I'm going to get deep in your asshole." She clutched the comforter with both hands and I could feel her try and consciously relax her butt. I took my opening, jamming myself the rest of the way in, moving my hand out of the way so my balls could go all the way up to her ass.

"Good girl!" Sam beamed. "Now give her your cum, Matty."

Without taking myself too far out of Mom's butt, I began slowly fucking her.

"Oh shit," I moaned, "oh shit Mommy, your butt is so tight. You're going to milk my cum out with your asshole." I felt Mom tense around me, and shoved back in again. "Fuck! Take my cum Mommy. Take it in your ass. I'm going to shoot it right up your fucking butt."

Sam stared at my cock shifting inside Mom's ass and I swore I could see drool forming at the corner of her mouth. "Fuck that ass, Matty. I want you to cum so deep cum drips out of her mouth. And I want you to tell your Mom how much you love her while you cum inside her fucking ass."

I held Mom's hips and started assfucking her faster. Every time my balls hit her rear, I felt my cum building and my voice increasing in intensity. "I love you so MUCH Mom. I love fucking your FUCKING ass. Thank you for taking my fucking CUM in your fucking ASS Mama. Oh fuck, let me SHOOT. LET ME SHOOT IN MOMMY'S ASS. CAN I SHOOT NOW MOMMY?! CAN I CUM IN YOUR BUTT?! CAN I SHOOT MY HOT CUM UP YOUR FUCKING ASS MOMMY?!"

Sam sat up enough for Mom to talk, and she rammed her hips back against my cock.

"Oh FUCK BABY, FUCK my fucking ASSHOLE Matty! Shoot my son's cum up my FILTHY SLUT ASSHOLE!"

"Do it cuz," Sam joined, "Shoot it now! Shoot it!"

"I'm going to cum, Mom! Get ready! Oh FUCK, I'm going to cum in your ass!"

I clutched at Mom's ass with both hands and screamed as I gave one final thrust. Her asshole pulsed open and then clamped around my cock along the entire length.

"OH FUCK MOMMEEEEEE!"

"FUCK ME BABY! FUCK MOMMY SO GOOD!"

"FUCK HER ASS CUZ! SHOOT IN HER FUCKING ASSHOLE AND LET ME TASTE IT!"

My balls clenched and a thick rope of cum shot through my body in an instant, exploding out of my cock into the Mom's vacuum-sealed ass.

"Oh FUUUUUUCK" Mom moaned as she took wave after wave of cum up her butt. I shot again and again, driving myself into her as deep as I could go. On each outward thrust she clamped her ass hard, milking more cum out of the length of my shaft.

"Let me taste it Cuz," Sam drooled, "Let me taste your Mom's fucking ass on your dick."

I slowly pulled myself out of Mom's butt. The second my dick was free, I saw pearly beads of cum squeeze out of her and run down to her pussy. She reached behind her and let the cum drip onto her fingers.

"Here, Sam," I said, holding my sticky cock out to her open mouth. She devoured it, only spending a second licking it before taking it deeply into her throat.

"Here you go, Mom," I said, guiding her cum-covered fingers to her pussy. "Shove my cum in your pussy." Holding her hand, I started fingerfucking her with her own fingers. My cum dripped down from her twitching asshole and she fingerfucked it straight into her pussy.

"Oh God Matty, yeah, I need your cum. I need your cum inside every hole."

Sam slobbered all over my dick while Mom played with my cum and watched.

"Taste my ass, Samantha," she said, "taste my ass all over my baby boy's cock. God, why did I wait so long to get assfucked by my son?"

I bent down and started licking the cum out of Mom's asshole. She increased the tempo of her fingerbanging. "Yeah, Mommy, get that cum inside. I want to be so deep inside of Mama. Oh fuck yes. Oh fuck, Sam, suck Mom's ass off my dick. Fucking suck that ass."

Sam grunted, a pig at the trough, and gorged herself on my dick as it slowly started to soften.

"Lick Mommy's ass, baby. You ripped up her fucking asshole, now you lick it and make it all better." I kept swabbing Mom's asshole, tasting her butt mixed with my own cum and feeling Sam's mouth suckle on my shrinking hard-on.

After a few seconds, I raised my head and took a deep breath, the orgasm finally leaving me entirely. I felt like it was the first breath I'd taken in minutes. Mom let her ass fall to the side and laid on the bed, leaking cum and grinning as if enchanted. Sam kept sucking me.

"Jesus, Sam," I said.

She broke away long enough to say "You know fat chicks, Matty. We'll eat anything," then went right back to slurping Mom's ass off of me.

Then my phone rang. It was my cell phone, which was in the living room charging, and given the circumstances, you'd think I wouldn't have given a fuck. Only I happen to have different ring tones for different people, and the ring tone playing now was the one belonging to my best friend, Josh.

I know what you're thinking. Still. Why answer it, right? Because that particular ring tone was a special one, used only in case of emergencies. Why we had to have an emergency ring tone is a story for another time, but the fact of the matter is, we'd promised always to answer if either of us invoked the forbidden ring.

"Fuck," I said, pulling myself out of Sam's mouth. "I mean...uh, that's Josh. I should take it."

Sam seemed to think that was the funniest thing in the world. Mom wasn't done grinning into space. I froze for a second.

"Well?" Sam said, "so answer it! Don't let us stop you!"

I didn't even bother to but my PJ bottoms back on as I ran out into the living room and snatched the phone off the coffee table.

"Hey, dude," I said into the receiver, "what's up?"

Josh was silent for a second. "Uh...listen, what are you doing right now?"

"I was fucking my mom in the ass," I said.

"Ha ha," Josh responded glumly. I frowned.

"Sounds serious. You need me to come over?"

Josh sighed. "If it's not...I mean, I know I'm going to see you alter at the party, but—I kind of need to talk to someone..."

"Can I get the details?"

"At my place. It's...about Brittany. And my Dad."

"Oh," I said. If it was anything like it sounded, it was definitely serious. "Okay, I'll be over in a few minutes." Josh lived just down the street from us.

"You don't have to man. I mean, if you're—"

"No way. If there's a [Britney Emergency], I'm coming over."

"Great," Josh said. "That's really...thanks."

"No problem."

"See you in a bit."

I hung up the phone, mind already racing as to what Josh's situation was, and if I should tell him about my morning before or after, or at all, or what. I ran upstairs and threw clothes on, spraying myself with cologne to hide the thick smell of sex. It didn't completely work, but I didn't think Josh would mind. He knew all about Lisa and I, just like I knew about him and his little sister Brittany and his brother Danny. Another thing we had in common was that both of our Dads knew nothing of our sexual habits. I was hoping we still had that in common as I rushed back down the stairs.

Mom and Sam were gently sixty-nineing on the living room couch, lapping at each other's well-used pussies like mother cats. Mom eyed me as I came downstairs and gave Sam's puss a big lick.

"What was that all about? We need to talk about some things, Matthew." Somehow, she had gone right back to being my Mom. It was an amazing talent.

"Can it wait? Josh is having some kind of emergency."

Mom frowned, but when Sam started sucking on her clit her demeanor instantly improved. "Fine, but only because it's your birthday. But we do need to talk. After the party."

"After the party," I agreed and ran over to the couch. I gave Sam a big upside-down kiss that tasted like Mom's pussy and ass.

"Be back soon. That was really fun."

"That was fun, cuz," Sam giggled.

Unable to resist, I gave Mom's asshole one last thorough lick. "By Mom. Love you."

"Bye baby. Love you too." Then her face was buried between Sam's thighs and I was out the door.

************

My resolve and loyalty were tested before I even reached the front yard. As I rounded the house, there she was: Lisa. My big sis, here for my birthday party. As her face split in a grin and she ran towards me, I reprimanded myself for forgetting all about her arrival.

"Baby b!" she yelled, her green eyes lighting up and her tiny body smacking against mine. She managed to push me up against the side of the house, out of sight, and immediately wrapped her arms around my neck and breathed into my ear:

"Happy birthday baby brother."

"Lisa" I said, semi-stunned, "I missed you." We kissed. Then she sniffed, wrinkling her petite, freckled nose.

"You smell like sex."

"Mmm," I admitted, adding, "you too." Which was true, but not unusual. Lisa carried a cloud of pheromones with her everywhere. I was feeling bold from the morning's escapades, so I slid one hand up under her microminiskirt and started fingering her asshole. Lisa was an anal fiend, and her asshole and I were practically best friends.

"Oh God yes," she said, "come to the toolshed or something. I've been waiting for an assfuck from my little brother for months."

I knew I had to go, but I didn't feel like taking my finger out just yet, so I changed the subject. "How'd you even get here?"

"Hitched. Fuck my ass Matty. Come on."

"Hitched? Dressed like that?" Lisa was wearing nothing but her skirt and a sports bra. She wasn't even wearing shoes.

"Let's just say you should [Never Eat Out In Texas]," she said.

"What's that supposed to mean?"

"It means," she grumbled, tightening her tiny butt, "stop fooling around and come. Fuck. My. ASS."

"And who would give you a ride?" I continued, ignoring her. That's like [Riding With The Devil]."

She reached down, pulled my finger out of her ass, and tried to drag me towards the back. "Come on Matty, don't make me beg. There isn't enough time. I need you inside me."

Finally, I had to sigh. "I know sis. Me too. But I've got to go now."

"What?!" Lisa roared. I started backing towards the gate to the front lawn.

"I've got to go over to Josh's. I'll be right back, I promise."

Lisa's face was already turning red with anger and disappointment.

"What gives?!" she yelled, "Who's smell is that on you?!"

I opened the gate. "Let's just say wishing me a happy birthday is kinda redundant." I grinned and step through, reveling in the confused, angry look on Lisa's face, if only because I knew as soon as she stepped inside the house, things were going to [Change For The Better].
