Sexy sibling

Poppy carefully rolls off me away from her sister. She shudders when she feels my cock leaving her. "Wow, I can feel your cum leaking out of me. You really filled me up!" She whispers in my ear. I look back at an unusually silent Mella who for some reason is staring open mouthed at me while still rubbing herself.

"You should do that to Sarah. She's a deep sleeper and sometimes masturbates in her sleep anyways." Poppy continues.

I turn my head to look at her, "How exactly do you know that?"

She blushes again, the red showing up startlingly well on her pale skin. "I sometimes sneak into her room to watch her play with herself. She's never noticed, not even when I pull the blankets down or accidentally make a loud noise. A few times I even put a dildo in her hand and she fucked her pussy with it."

Poppy is way kinkier and perverted than I expected. She should help me have lots of fun. "Ok, let's do this. Let me know what I can do to make it better." Poppy nods enthusiastically.

I carefully roll on my side behind Sarah and snuggle behind her. My hard cock, still wet from being in Poppy, is poking her right in the butt. I carefully shift myself down a few inches to get in a better position. Poppy helpfully peels back the covers revealing Sarah's shapely bottom and long tan legs.

I start slowly rocking my hips as my cock nestles between her thighs right under her butt. I gently start kneading her breast and with my hand on her hip. Her slight snoring turns into a slight moan. We're getting somewhere.

Again Poppy is very helpful as she slowly lifts Sarah's leg to allow me easier access. She does it with what looks like practiced ease. I really want to ask her some pointed questions. That's for later though. Right now I have a hot buxom teen to fuck.

With her legs spread my cock rises up between her legs and with a little help my shaft is on her pussy. Within a few minutes of gently rocking my cock is slick with her juices as it slowly saws between her folds. I never quite push in but the head of my cock bumps her clit on each slow cycle. Sarah is moaning with every breath now and I am concerned about her waking Kelly up. She solves that herself by rolling her face into her pillow to subconsciously muffle her sounds.

She starts rocking her hips in time with me to get a longer stroke across her pussy. I can hear her muffled moans get louder and I feel little tremors running through her body. I slowly ease of my thrusting until I stop entirely. I slowly bring my hand up to her other breast and gently squeeze both of them. Her long moan of pleasure turns into a whine of disappointment as she is not getting as much stimulation on her pussy anymore.

Her free hand blindly fumbles around until she grabs my cock. She pulls it almost like she would pull a dildo and gets frustrated when it doesn't move as expected. She fumbles around more until she presses my cock against her pussy and rubs it back and forth against her clit.

I notice both Poppy and Mella at my feet staring in rapture at the proceedings. Sarah finally has enough with the foreplay and rather forcefully pushes the head of my cock into her pussy. Once inside her tight warm folds she sighs contentedly before starting to rock her hips again, slowly fucking me.

I lay there letting her fuck herself while I slowly keep playing with her large breasts, careful not to do anything that might wake her up. She keeps it up for several minutes of sexy sleep fucking before she cries in frustration again. She must really want to have an orgasm.

She fumbles around a little bit before her hand finds her pussy and she starts to play with her clit. That does the trick and in less than a mimute she is moaning into her pillow and bucking her hips against me. Her inner walls spasm and tighten around my cock and with a stifled grunt I grab her breasts hard and pull her to me as I shoot my cum in the hot teen's pussy.

She writhes against me for a minute before she settles down and with a long contented sigh she seems to fall back to sleep. I carefully pull out of her and gently disentangle my arms, giving her a pillow to hold instead.

Poppy carefully sets Sarah's leg down, "She'll be out at least 15 minutes after something like that. You can move her around or touch her or make some noise and she won't budge." I want to ask her even more pointed questions but instead I glance at Kelly. "She is like Sarah but she always plays with herself laying on her back."

Mella has been standing there with her mouth open the whole time and she finally bursts out, "WHAT THE FUCKING FUCK!? HOW THE FUCK IS THIS HAPPENING? DO KELLY! DO HER! DO HER! DO HER! I HAVE TO SEE WHAT HAPPENS!"
