Wake up sleepyhead, it's morning! What kind of naughty stuff are we going to do today? Hey wake up Kelly, we have lots of stuff to do before Mom and Dad get home.

Looking down Nikki saw her sisters still wet panties laying on the floor, and picked them up.

What's the matter Kelly, these too wet to wear last night? God I guess so, they're still pretty wet now. But hmmmmmm, they sure do smell nice.

Kelly sat up in bed and grabbed her panties from under her sisters nose.

Jeeze Nikki I just thought of something, we better do some laundry before Mom and Dad get home. If Mom sees the condition of our panties, she'll know we've been up to something, we'll be in trouble for sure. Go gather up all the panties you've worn so far this weekend, and I'll do the same and meet me in the laundry room.

Kelly sprang from her bed, only wearing the oversize T-Shirt from the day before. Nikki could see her butt sticking out whenever she bent over to pick up her discarded panties off the floor. Kelly started to pull her T-Shirt over her head exposing her pert breasts, her nipples still somewhat swollen and sensitive.

Hurry up Nikki, go get your stuff! Grab all the underclothes you wore this weekend, we'll wash those to just in case.

Kelly was already in the laundry room when Nikki came in with her arms full of panties and various other underthings. Both girls had changed into clean panties and over sized T-Shirts. Kelly had already put her things in the machine, and grabbed Nikkis stuff as soon as she came in. Kellys fingers just happened to touch a pair of Nikkis panties that were somewhat warm and damp, she quickly held the damp panties to her nose and inhaled her sisters fragrance.

Ooooh Nikki you must have just taken these off, they're still warm and damp. Were you having some naughty thoughts already this morning? They smell yummy. And you have some really cute panties to Nikki, mind if I borrow a few sometime.

Nikki grabbed her panties from Kelly and thew them into the washing machine, feeling somewhat embarrassed.

God Kelly first you smell my panties, and now you want to borrow them!

Well Nikki you just sniffed my panties up in my room, why can't I sniff yours to. And what's wrong with me borrowing some of your panties, or you borrowing mine? I think it would bring us even closer, we are sisters after all. Sisters do borrow each others clothes, you know. As a matter of fact why don't we exchange panties right now. You wear mine, and I'll wear yours. Come on it'll be fun, you'll see.

What Kelly you want me to wear your panties, and you wear mine? Right now....?

Yeah come on Nikki take your panties off, and I'll do the same.

So each girl pulled down their panties and stepped out of them. Kelly handed her panties to Nikki, and hesitantly Nikki handed her panties to Kelly. Then each girl pulled on the other girls panties. Immediately they could feel each others warmth and slight dampness, and it sent an incredible thrill through them both. Kelly even reached down between her legs and brushed her fingers over her sisters panties, and she knew right away that this was something very special she was sharing with her sister Nikki. It made her weak in the knees. And Nikki had a look of astonishment on her face, like she couldn't believe what she was feeling. Both girls knew that they now had a bond that probably no two sisters ever had before. I truly was a beautiful thing.

Wow Kelly this is so unbelievable, I can feel you, in your panties. I can feel your warmth, and your dampness. This is so wonderful and exciting.

I can feel you to Nikki, I told you this was going to be great. As soon as this machine stops and the clothes in the dryer, wait maybe we should grab some breakfast first. But after that we're going back to my room and we're going to have some fun, this is going to be a great day Nikki.

As the girls sat having breakfast, they talked excitedly about the things they had been doing. Neither one of them could wait until breakfast was over to do even more experimenting and exploring. Kellys mind was working overtime with all the things she wanted to do with her sister, now that Nikki knew the joy and pleasure of a girls orgasm. And Nikki was overly excited to be talking about these things with her sister, and happy that Kelly helped her learn how to pleasure herself. And Nikki was beginning to feel a lot more comfortable doing these things with her sister, and was starting to feel like she wanted to do even more. She was like a sponge soaking all this information in. By the time they finished breakfast both girls had each others panties wet with anticipation, and they walked hand in hand back to Kellys bedroom.

Nikki Mom and Dad will be back tomorrow and this is our last day alone, I would like to do something really special today. But only if you're comfortable with it, I don't want to push you into anything you're not ready for. OK?

God Kelly you mean we're never going to be alone after today?

Oh no Nikki, we're just have to be more careful when Mom and Dad around. It's not like we're never going to be alone again, we'll have plenty of opportunities.

So just what did you want to do today Kelly, how special.

Well Nikki I would like to show you just how amazing another girls hands and fingers can feel on your body, I would like to masturbate you. I want to play with you, but only if you're comfortable with it. I don't want to go too far, too fast with you. But I'm sure you're really going to like it. What do you say Nikki?

Well sure, I guess Kelly I'm still pretty new to all of this. I mean I know I can play with myself you taught me after all, I just never thought about another girl doing it. What do you want me to do.

That's just it Nikki, you don't have to do anything, I'm going to do it all for you. You're going to love it.

Kelly went over to her closet and opened the door, so the mirror on the back of the door was facing her bed. Kelly often masturbated this way, it was so erotic to watch herself in the mirror while she pleasured herself. It was going to be even more erotic to watch while she brought her sister to orgasm, with her own fingers. And it was going to be erotic for Nikki to watch to.

Kelly climbed on her bed with her back to the headboard, just like always.

Now Nikki come and sit here between my legs, and we can watch ourselves in the mirror while we play. It's be like watching a very erotic video, of two girls playing with each other. Except it's going to us we're watching.

Nikki did as she was told and got on the bed sitting between her sisters spread legs. Nikkis own legs were spread and her knees up, her sisters ever dampening panties pulled snugly over her pouting mound. Her butt pushed firmly back against Kellys crotch, Nikki could feel kellys warmth and wetness. Kelly kept her crotch firmly pressed into her sisters butt, feeling Nikkis heat through both pairs of panties. Kelly had her arms around her sisters waist, and her chin on Nikkis shoulder. Nikki had her arms around Kellys thighs, like she was hanging on for the ride of her young life. The image in the mirror was the most beautiful sight in the world, two sisters about to play out a very intimate act. Kelly moved her hands up to her sisters breasts, and began to rub Nikkis nipples through her T-Shirt. Nikkis butt pressed back even further into Kellys damp crotch, putting even more pressure on her sisters pussy.

Look Nikki isn't that a beautiful reflection in the mirror, of me playing with your breasts. Your legs are spread and you're wearing my panties, and look at the damp spot on the crotch. Isn't this sexy Nikki?

Nikki had a dreamy far away look on her face, and all she could do was nod her head yes. Nikki was enjoying her sisters attention very much, almost as much as Kelly was enjoying giving Nikki this intimate pleasure. Kelly was getting so turned on watching their reflection in the mirror, that she had her sisters panties soaking wet. And it didn't help that Nikkis butt was pushing back into Kellys pussy, and Kelly was humping against Nikkis butt. Kelly reached down into Nikkis/her panties first with one hand, and then the other coating her fingers with her sisters cream. She then brought both hands up under Nikkis T-Shirt and rubbed her wet fingers all over her sisters hard nipples.

Ummmmm Kelly, that feels nice.

Isn't this wonderful Nikki, watching in the mirror while I play with you? How do you like your pussy cream on you nipples, doesn't that feel great? And Nikki if you keep rubbing your butt against my pussy, I'm going to come before you do. I'm the one who's supposed to be masturbating you, you know. And your back is rubbing my nipples, you're driving me crazy Nikki.

Kelly I love the feel of your slippery fingers on my nipples, I can even smell myself. And watching you play with me in the mirror is driving me crazy. I can't hold still I want you to touch me down there, PLEASE. Kelly play with my pussy, I can't take much more of this. Make me come, please Kelly.

Just be patient Nikki, I'll get you there soon enough. Just enjoy the sights, smells, and feelings. When your orgasm finally does come, it's going to wipe you out. You'll see.

Kelly reached back into her sisters panties to re lubricate her fingers, and Nikki arched her butt up to try and make Kelly keep her fingers there a little longer. But Kelly pulled them out too quickly, and went back to playing with her sisters nipples. Poor Nikki was desperate to have an orgasm, but Kelly wasn't going to let her come until she was good and ready. She was just going to have to wait. Kelly rolled Nikkis nipples between her thumb and forefinger, every now and then she would pull her sisters nipples. Every time Kelly pulled the young girls nipples, Nikki scooted her butt back even further. Putting increasing pressure on Kellys crotch, bringing her closer to orgasm. Something Kelly wanted to delay as long as possible, for the both of them. Nikki could feel Kellys girl cream leaking through her panties, making her butt cheeks all wet and slippery. Nikkis hips started arching up off the bed as if to make contact with some imaginary lover or object, anything to touch her and make her come. This was pure agony for Nikki wanting to come so badly, and Kelly wouldn't let her. As Kelly continued to roll her sisters nipples, she whispered in Nikkis ear.

Nikki I'm not being mean, I just want you to have the best possible orgasm ever. This is our last day alone before Mom and Dad get home, at least for a while anyway. I just want it to be special for you. And it will be special, you'll see. A little preview of more things to come later, that is if you want more things. We'll have plenty of opportunities to be alone together, don't worry about that. We'll just have to plan and be careful, that's all. And nothing says we can't get together with other girls at their houses either. That's if you want that Nikki, you don't have to. But it's really fun to be with other girls, and have them touching you all over.

All Nikki could do was look up into her sisters eyes and whimper, pleading with Kelly to let her come. Kelly kept rolling Nikkis nipple with one hand, and with her other hand started to stroke Nikkis thigh. Kelly would bring her hand up Nikkis thigh, and just brush her wet panty crotch. She never let her hand linger at Nikkis crotch for very long, she wanted to keep her sister one the edge a while longer yet. Back and forth over Nikkis thigh for several agonizing minutes, driving her sister wild. Kelly then reached between her legs and started to fondle Nikkis soft butt through her panties, tracing her fingers up and down her crease. Nikkis panties were wet from Kellys crotch rubbing against them, Nikki lifted her butt off the bed to give her sister better access. Kelly got her fingers under the crotch of Nikkis panties, and started to finger her sisters anus. Nikkis cream was running down lubricating her tight anus, letting Kellys fingers glide easily over her sisters most intimate opening. This was the first time anyone, other than herself had ever touched Nikki there, and couldn't believe how good it felt. Nikkis butt was rising and falling, each time her butt came down it put more pressure on Kellys finger at her tight opening.

Kelly that feels so good, nobody's ever touched me there before. God Kelly you're driving me crazy!

The increased motion of Nikkis butt was also causing more friction on Kellys panty covered pussy, pushing even closer to a much needed orgasm. Both girls were on the brink, almost to the point of no turning back. Much to Nikkis disappointment Kelly removed her hand from her sisters panties, Kelly wanted to try something else with her sister. Kelly reached down the front of Nikkis panties and ran her fingers over and through her sisters wet lips, coating her fingers with Nikkis juices. She then brought her wet fingers up to Nikkis face and brushed her sisters lips, Nikki instinctively began to lick Kellys fingers, then sucked them into her mouth. Cleaning her sisters fingers of all her cream, and tasting herself for the very first time.

You like Nikki?

Yeah Kelly I do, I really think I do. Do all girls taste that good? Can I taste you some time Kelly?

Nikki all girls do taste good, different but good. Of course you can taste me Nikki, I thought you would never ask. But first I want to taste you.

With that Kelly returned her fingers to Nikkis panties and coated her fingers with her sisters cream, then brought her wet fingers to her mouth and sucked them clean. Just tasting her sisters pussy juice on her fingers was almost enough to put Kelly over the edge. Nikki was looking up at her sister as she licked her fingers clean.

Do I taste good Kelly?

Without a doubt Nikki, you are the best girl I have ever tasted. For that matter, the best girl I ever will taste.

Really Kelly, can I taste you now?

This time Kelly put her fingers down the front of her own panties and coated them with her cream. Then brought her soaking fingers to Nikkis mouth, her sister sucked her fingers clean like a baby sucking a nipple. Both girls knew that they were sharing something very special, something they were going to remember the rest of their lives.

Ummmmmm Kelly you taste yummy, I love it!

Just wait until you taste it from the source Nikki, it's even better.

You mean like down there, lick you Kelly?

That's exactly what I mean Nikki, licking me. Licking each other, it's wonderful. And if you think me palying with you feels good, licking feels even better.

Kelly do you mean girls actually lick each other, down there, on their pussies?

Of course Nikki, how did you think girls did it?

I don't know Kelly, I guess I never really thought about it before.

Oh Nikki there are so many things I want to show you that girls can do together, this is only the beginning. But only when you're ready, I'm not rushing you into anything. But right now little sister I really need to come, and I think you do to.

And Kelly returned her hand down the front of her sisters panties, and began running her fingers up and down Kikkis wet folds. Spreading her lubrication all over Nikkis excited pussy. Kelly even let her finger tip part the lips of Nikkis pussy, and enter her slightly. But just slightly, Kelly didn't want to go too far this first time. And Nikki was really enjoying her sisters attention, and getting closer to the orgasm she so desperately needed. She couldn't hold her butt still, it kept rubbing against her sisters pussy. And of course Kelly kept humping her panty covered pussy against Nikkis butt, driving her even closer to orgasm. Neither girl was bothering to look at their image in the mirror anymore, their eyes were closed tightly concentrating on their impending orgasms. But their reflection in the mirror was pure and innocent lesbian erotica, the kind only two sisters can share. Both of their bodies thrashing wildly, desperate for orgasm. By this time Kellys fingers were a blur of motion under Nikkis soaking wet panties, as were Kellys panties soaking wet from rubbing against her sisters butt. Kelly was running her hand down to the bottom of Nikkis pussy collecting lubricant, then bring it back up to her sisters hard little clit. She was rubbing Nikkis clit with the pads of all four fingers, driving her young sister crazy. Both girls were on a sexual sensory overload, ready to explode at any moment.

Nikki I can't last much longer, I'm really close. Lets try and come together.

Me to Kelly, I'm really close to. Yessss please come with me. Now Kelly, now!

Me to Nikki, I'm coming to! Oh God Nikki am I ever coming!

The reflection in the mirror was quite different than it was just a few minutes earlier. It was now of two very happy, very sexually satisfied girls entwined in each others arms and legs. A large wet spot on the bed under them, and the room filled with the scent of the girls arousal. Their sexual discoveries just beginning.
