Episode 4.

Kelly Kapowski was absolutely thrilled that her sister Nikki wanted to masturbate with her, something she has wanted for a very long time. Kelly wanted other things to from her younger sister, but this would do quite nicely for now. Kelly got out of bed and started to pull her large T-Shirt over her head.

Kelly what are you doing?

Well Nikki I'm getting undressed so we can masturbate.

Do we have to get undressed Kelly? I'm sorry but I'm still a little shy about all of this, and I guess I'm a little overwhelmed that you want to masturbate with me.

I understand Nikki, we don't have to get undressed. We can masturbate together in our T-Shirts and panties. We can either masturbate through our panties, or under them. And of course I want to masturbate with you Nikki, I've wanted this for a very long time. It's going to be beautiful, a bonding of sisters. I can't think of a better way for sisters to bond, than for them to masturbate together. Besides I think it will be much more erotic if we leave our panties on.

Yeah Kelly it'll be just like when you and Jessie did it in front of those boys, except no boys!

Kelly climbed back on her bed, opposite her sister Nikki. She sat back against the headboard of her bed, just like the first time she masturbated for Nikki. Kellys panties were already quite moist from the excitement of all this masturbation talk. Kelly was going to have to pace herself so she wouldn't come too quickly, it was going to be a challenge to say the least. Kellys panties were already stretched very tightly over her smooth mound, and creating some friction on her sensitive clit. She knew she better not touch herself down there, or it would be over before it even got started. So she tried to prolong it by playing with her breasts, at first just cupping them through her T-Shirt. And eventually started to roll her stiff nipples between her thumb and forefinger. When she looked at Nikki she was sitting with her legs crossed in front of her, stroking her thigh with one hand, and rubbing her nipple with the other. She had a dreamy look on her face, and was looking directly at Kelly.

God Kelly your panties are so tight over your mound, and their already wet. I can see right through them, it's so sexy.

Glad you like Nikki, it feels sexy to.

With that Kelly stopped playing with her boobs to reach down and pull her panties even tighter, the soft panty material felt wonderful rubbing against Kellys tender pussy. She even reached inside her panties to pull back the hood of her clitoris so Nikkik could see how swollen it was. And Kelly knew she wouldn't last long if she kept up this panty play, especially with Nikki watching her, she had to stop. Kelly slowly ran her hands back up to her breasts, hoping to prolong her pleasure so her and Nikki could come together.

Nikkis hand moved from her thigh and was rubbing her own pussy through her panties, just like her sister was doing. Her own panties getting increasingly moist as she watched her sister masturbate in front of her. It was the most erotic display that young Nikki had ever saw. Kelly was right, a girl masturbating truly is a beautiful thing. Even Kellys T-Shirt was becoming transparent from the perspiration, as she played with her boobs. Kellys panties now were positively soaked with her girl cream, as she slid her fingers under the elastic leg band. Her fingers clearly visible and moving under the wet panty material, as she rubbed her puffy lips.

Oh my God Kelly, your panties are so wet I can see your fingers through them. I can see them moving, I can see you playing with yourself. That is so sexy Kelly.......

Nikki pull your panties up tight, I want to see to.

Nikki did just that. She arched her back and lifted her butt off the bed, and pulled her panties up tight against her tender pussy. She sat back on the bed knees up and spread, her panties pulled tight against her mound, and her sparse pubic hair just visible through the material. And she was amazed at how wonderful the panty fabric felt against her young pussy, even though her panties were nowhere near as wet as Kellys it still felt great.

Kelly I'm afraid my panties aren't as wet as yours are, but it still feels nice.

That's OK Nikki just keep playing with yourself, your panties will be soaking wet in no time.

Nikki gently brushed her fingertips over the tight panty material covering her pussy, and could feel her girl cream begin to flow. And she loved the feeling of the wetness on her panties and her fingers, as the panties became wetter. The extra wetness was making it feel even better as Nikki continued to rub her pussy. She started to reach further down to collect more of her cream, then bring the wetness to the top of her pussy to her clit. The extra lubrication on her swollen little clit felt wonderful, Nikki was spending more time rubbing her clit after she collected more cream.

Nikki reach under your panties and pull back the hood of you clit, it will feel even better.

Nikki reached under the waistband of her panties and pulled back the hood exposing her tender clit, then pulling her panties back in place. Nikki was amazed at how much better it felt with her clit exposed, as she rubbed it through the wet panty material. This was the best feeling yet in Nikkis masturbation discoveries, Kelly was right again. Nikki continued to rub her clit in tiny circles, causing even more of her cream to flow and soak her panties. Every now and then Nikki would brush her fingers past her lips to collect more cream, then go back to rubbing her sensitive little clit.

See Nikki, I told you your panties would get wetter. Your panties look so hot stretched over your pussy as you masturbate through them. I don't know how much longer I can last Nikki, I'm really close now. This is more of an overload that I expected, masturbating with you, my sister. Nikki this is the most erotic experience of my life. I'm positively gushing cream as I'm sitting here playing with myself in front of you.

Kelly pulled her fingers from the leg band of her soaking panties, and brought them up to her lips, then licked her own cream off her fingers. Nikki sat wide eyed as she watched her sister lick her own girl cream off her fingers. Nikki wasn't sure she was ready to try that just yet, but it sure was sexy watching Kelly do it.

Kelly I think I'm really close to, I'm so soaking wet. It feels so good rubbing my clit through these wet panties, then watching you lick your own cream off your fingers. It's just too much Kelly.

I'm almost there Nikki, I'm almost there.

As Kelly removed her fingers from her mouth, and went back to rubbing her pussy through her wet panties. She was rubbing her pussy with one hand, while rubbing her nipples with the other. She was quite surprised at how sensitive her nipples had become, she couldn't remember them ever being so sensitive. Kelly pinched her one nipple between her thumb and forefinger, and her pussy gushed out a stream of her girl juice. Something that never happened to her before, either masturbating or with another girl. Kelly was going to have to explore this nipple play more, she loved the feeling it was giving her. And she loved the feeling of her pussy squirting cream through her panties.

Now Nikki, Now! Please come with me Nikki, please! Oh Nikki this is the best ever, ohhhhhhhh Nikki! This is sooo good, Nikki..............

I'm there to Kelly, I'm coming to! I couldn't believe what I just saw, when your pussy squirted cream right through your panties. Oooooh Kelly this is too good, I'm coming with you Kelly, I'm coming with you..........

Both girls bodies thrashed wildly on the bed, as each girl went through her thunderous orgasm. Their hips rising and falling frantically, hands between their legs rubbing their pussies through their soaking panties.

Then it was over, both girls lay spent with their chests heaving. It was the most beautiful thing either sister had ever experienced. The true bonding of sisters, the sharing of the exquisite female orgasm, through masturbation. It doesn't get any better than that.
