Part One: Jim

I took my coffee out to the back yard, hoping that the crisp morning air might help bring me into focus. Seeing Terri naked, and a young woman, on top of seeing her mother going down on our son, while piston driving her greedy hole with her fingers, simply had my head spinning. And it was worse still. Having married, Lisa, my high school sweetheart, Terri, was only the second nude woman I had ever been in the same room as, and, although I swear that I could never touch her, the sight of her young body aroused me. Realizing this, made me feel doubly uncomfortable, but beating myself up over it would have to wait. I had a family to save, and had to figure out how. I would have loved to have talked it over with somebody, but, for obvious reasons, that was a non-starter. Talking to Rob about it just didn't seem right, and Terri should never know, if I could help it. That just left Lisa. I had to choose between pretending I had never seen what I had, or doing something I hate almost more than anything, confronting her. I couldn't let this go on, so I was just going to have to man up.
Soon the house was bustling; the kids getting ready to head off to go hiking with friends, and Lisa was fussing over everyone' breakfast. It felt normal. It felt good. It was as if the last eight or nine hours had been some alternative reality, and now I was back in my own world. Trying not to be too obvious, I watched Lisa and Robbie for any sign of what I had seen. But no, everyone just seemed happy and normal.
Once the kids had left, Lisa, washing up the dishes, asked me over her shoulder, "What got into you last night tiger? I'm not complaining, it was great, but not really like your usual self. Have you, finally, spent so much time in the bush that you are turning into a caveman?"
I looked at her as she busied herself scrubbing the pan. Her ample ass jiggling as her arm scrubbed. There would be no easy way, not perfect time, so I just blurted it out.
"I saw you with Rob last night".
Everything just seemed to stop; her scrubbing, my breathing, and even time.
"I mean, Jesus, Lisa, he's our son!".
I watched her back as she set down the scrubber, then put her two hands on the counter to support herself.
"I need to sit down Jim", she said, making her way to the table, "and I could use a bourbon. Could you get me the bottle and a glass? Better make that two glasses, Jim."
Despite being 9:30 in the morning, bourbon did seem like a good idea.
When I returned from the cupboard, bottle and glasses in hand, Lisa was softly crying. I poured two good measures and passed one to her. The crazy thing is that I wasn't mad at her. I just needed to make sense of it all. Lisa downed her glass in a single swallow and silently passed the glass back to me. I poured her another shot, passed it to her, and waited as she composed herself.
"Are you going to divorce me?", she managed in a timorous voice.
Just hearing the word; hearing it said by the only woman I had ever loved, was enough to scare me to the center of my soul.
"Lisa, god damn it, no! I just need to understand, because I am absolutely lost here".

Part Two: Lisa

When I had first proposed that we become family nudists, I had factored in that the kids would probably explore each other a little. Having, myself, when I was young, fooled around with my own brother a little, I saw it as pretty natural and essentially harmless. What I didn't factor in was the fact that I would be turned on as well.
That first day, we all ended up having a long talk.
First, I explained to Robbie that he didn't need to hide his erections; how he had a very nice cock and that it was nothing that needed hiding. I remember how he had glanced over at his sister, she had shrugged, and his attitude had changed. He had turned to lay fully on his back, his hands behind his head, with his smallish, but fully erect, penis reaching to the sky. In just a few moments, he had shifted from shame, to being rather proud. Terri and I, on the other hand, were doing our best not to stare; her because it was the only prick she had ever seen, and me, because every time I looked at him, I just wanted to run over and take that beautiful young cock into my mouth! I had not seen that coming. To this date, I swear to the gods, that that boy is always hard. On those rare occasions when he was not, I wanted to take his softness into my warm mouth until he was! Seeing him, his sweet cock, and his pride in it, made me love him and want him, all at the same time.
Bringing my attention back to the topic at hand, I made it crystal clear that there were limits. I explained how it was a real gift that we were able to be this way with each other, but two things could turn our secret fun into a tragedy we might never recover from. Though the kids were too green to even have ever contemplated it, I laid out the rules. House rule one: no fucking! House rule two: all of this needed to stay just between the three of us! To their credit, the kids did ask about their dad, but all three of us, in our hearts, and as much as we loved him, knew that he would never understand.
The basic, but extremely important rules established, and agreed upon, the kids had some questions of their own. The first one almost sent me into cardiac arrest.
After some seemingly considered thought, Terri asked if touching was okay. Thinking that see was speaking of her touching her brother, I replied that it was okay, as long as the other person agreed. Obviously taking me seriously, she hesitated, then said something that took our whole journey on a path I had never envisioned.
"Can I touch your breast mom?", she asked.
"Yeah, me too", my little man added.
I was caught completely off-guard! I, honestly, had no idea what to say! I looked at them dumbfounded and saw their eagerness. I knew that I was about to cross a line. I knew that something inside of me had already crossed it. I just groaned and nodded my head in the affirmative.

Part Three: Terri

As great as all the days since have been, that first day will forever be burned into my memory. Back then, in my understanding, there were no labels; straight, bi, gay, just the fact that my mom's breasts were full, soft, and topped by big brown nipples I just really wanted to suck. I will never forget her saying yes. How Robbie and I approached, in awe, and looking at each other, reached out and began to feel mom's breasts. They were so soft and beautiful. I will, also, never forget how mom began to moan as we squeezed them; how she guided our heads down to suck her nipples. As Rob and I greedily sucked on a nipple each, mom moved her arms around us to draw us closer. In my young life, I had never before felt like this; abandoned, lustful, and needing something without knowing what. Reaching across my mom's belly, I grabbed my brother's cock in my hand. My hand which had never touched a cock before began to touch him, running my fingertips over the tip, along the shaft, down to his balls, then making a fist around his hardness, I began to move slowly up and down. My mom started to thrust her ass and pelvis forward as her excitement built. My virgin slit was on fire, and when mom grabbed my wrist and directed it to her own hot hole, I instinctively knew what to do. With one hand on my brother's throbbing dick, and the other rubbing my mommy's clit, I felt on fire.
Suddenly, mom sat up, pushing us gently away from her.
"Over there", she commanded. Indicating the lawn. "Lay down", she said to me in a deep, throaty voice.
Kneeling beside me, she placed one hand on my shoulder, pinning me in place, while with the other she began to touch me; first my hair, then my face, my stomach, my ass, my legs, then, finally, my breasts. Then straddling me, she bent over and repeated the process, but this time with kisses and small flicks of her tongue. I closed my eyes to drink in the sensations without distraction. Every touch of her lips or tongue set off an electric current running straight to my young cunt and driving me out of my mind.
When I opened my eyes, I could see that mom had positioned Rob beside us. He was kneeling, wide eyed, with one arm on the ground to support himself. He was actually trembling all over and looked like he might just pass out any moment. His cock was pointing up with a little string of pre-cum hanging from it.
Glancing over at him, mom told him to pay attention, that she was about to teach him one of the most important lessons of his young life; how to please a woman. And with that, she slid down, pushing my skinny legs wide apart, and began to kiss and lick my virgin pussy; her tongue flicking my nub one moment, then lapping at my wet hole the next, sucking my juices. When her tongue suddenly pushed between the lips and slid into my little hole, it was more than I could bear.
"Mom", I moaned, my hips rising while wave after wave of energy flowed through me. I shuddered, clenched, my young vagina contracting. Looking up, I watched as mom reached a hand over and began fly up and down on my sweet brother's cock. I could not stop the next wave that washed over me. I came, ferociously, completely, and with an intensity I could have never imagined.
Suddenly my mom was kissing me; deep, soulful, tongue kisses, then disengaging, she leaned over and wrapped her mouth around Robbie's cock, teasing his balls with her hand. Within a few seconds, I watched as Robbie threw his head back, his young back arched, and a series of spasms convulsed him, as shot his young load into mom's mouth.
Holy shit!

Part Four: Lisa

In the years since that first day, the kids and I had become a very tight unit; family, lovers, and, as time has gone on, even the best of friends. We are more like a married threesome, than an adult and two teens. Of course, the kids are free to date or see anyone they wish, but neither of them have ever showed any real interest. The problem, in fact the only problem that I could see, is that as the three of us grew closer together, the more Jim became like a favorite uncle, rather than someone who shared equally and fully in our lives. There is no doubt we all loved him. Jim is the kind of guy everybody loves. We were always happy when he would come home from the camps, and everyone would work hard to see that he was happy too. We appreciated him, but as the week off wore on, we would all become restive; anxious to once again shed our clothes and inhibitions.
Bringing myself back to the breakfast table, my empty bourbon glass, my poor husband's eyes, it came to me that this needed to be a family discussion, and not mine alone.
"Jim, honey", I began, "Whatever things might look like to you at this moment, however horrible or confused you might feel, I love you, the kids worship you, and we are going to fix this. I am, however, going to need you to trust me just a little longer. Just a little bit, okay?" "Here is what I want you to do", I told him, warming to the sense of my plan. "You've been talking about driving into the city to get that part for the truck. I want you to do that today. "While you are there, I have a list for Costco, so you might as well pick that stuff up too. Take your time, because I don't want you home before six. Pick up some steaks, and when you get home, we will do a barbecue out back. I promise, when you get home tonight, I will explain everything then. Can you do that for me?"
Truth be told, Jim looked relieved. Sweetheart that he is, he has never been much on uncomfortable situations, nor is he much of a problem solver or planner. I had thrown him a lifeline, and he had grasped it with the relief of a drowning man.
Twenty minutes later, the truck was out of the driveway and I was on the phone.

Part Five: Rob

We had just parked and were getting our day packs on, readying for our hike, when my cell phone rang. Surprised to even have coverage here, I answered.
"Mom?"
"I need you and Terri to come home", the reception was shitty, but good enough to have me worried. "Something has come up, and I need you home", she added.
"What is it?", I asked, feeling a little alarmed. "Is somebody hurt, is it dad?"
"No, nothing like that. Will you please just come home and I will explain it when you get here. Please!'.
"Sure mom", I agreed , hearing her pleading tone, "We'll be about an hour."
Hanging up, I looked over to Terri, "Change of plans, we're needed at home."
On the drive home, Terri and I were both lost in our thoughts, and by the time we pulled into the driveway, we were both pretty worried.
Mom was out back, naked, sitting at the side of the pool with her legs in the water. Since it was a dad week, that just made everything seem all the weirder. I have to confess, that after all of this time, the sight of my naked mom or sister, still gives me an instant boner, so I was relieved when mom explained that dad wouldn't be home ‘til six, and we were free to disrobe; something we instantly and gratefully did. Getting up from the poolside, mom walked over to patio table, where a glass of wine stood waiting. Also weird, as mom, even though she enjoyed a drink, was not the kind of person to begin at noon. Sinking into one of the patio table chairs, she waved us over to join her.
As we sat, our curiosity senses on overload, she spit it out without preamble, "Your father saw me and Rob last night".
"Oh, Jesus mom", Terri moaned.
"Oh, shit", was all that I could manage.
"Yeah", was all mom had to add.
I suppose, in retrospect, it was crazy to think that we had thought that would be able to go on like this forever; two lives; two families, one with dad and one without. But now the moment of truth was here and the three of us, co-conspirators on a grand scale, were about to face the court of consequence. I, suddenly, became aware that, for one of the first times ever, while being naked with my mom and sister, I didn't even have a hard-on. This was serious!
"Jesus, mom, what are we going to do?", Terri asked pleadingly, looking as if her mug had just made "America's Most Wanted".
I knew how she must be hurting. Out of all of us, she loved dad the most deeply. She was daddy's little princess, and he was her knight in shining armor. Of course, we all loved him, but Terri was looking as if she was about to burst into tears.
Mom, lifted her wine glass, and tilting her head back, drank it all off in one long drink. Returning the glass to the table, she wiped her mouth with the back of her hand, leaned forward conspiratorially towards us and said. "Kids, I have a plan".
