Sleeping Rachel

You leave Claire to get ready for work and pass by Melanie still getting dressed. You head back into Rachel's room, step inside, and close the door behind you.

Creeping slowly to the edge of her bed, you peel the rest of the blankets off her body. Her second breast comes into view. Then her smooth, flat stomach, and then her little white panties. You reach out and gently massage her tits in your hands. Rachel let's out a soft groan but doesn't wake up yet. You get a little stronger with your squeezing and kneading of her breasts and slowly climb up onto the bed beside her.

Carefully, trying not to wake her just yet, you swing one leg over her chest so that you are straddling her face. Your balls barely an inch above her chin and your dick sticking out over her face. You lean forward a tiny bit and dip your balls right into her open mouth. Instinctively, she gently begins sucking on them.
"Yeah, baby, that's it."
Rachel seems to be slowly waking up now. You grow a little impatient and grab her head. Her eyes snap open and you press your weight down on her face to pin her down.
"Morning sis!"
She struggles beneath you as you grind your cock and balls into her mouth and nose.
"Hey now, hold still."
She stops thrashing but reaches up to your hips and tries to push you off her. With one hand on her head, your balls still in her mouth, you take your other hand and use it to slap your cock down on her eyes.
"Keep sucking those balls, bitch!"
Your little sister gives into your demand and starts sucking on your nuts again. While she does, you rub your dick all over her face. Then you pull up, and point your dick down into her mouth and thrust forward.

"Suck it, baby, yeah!"
Rachel snaps her eyes shut and screams around your cock as it hits the back of her throat. Your wet balls now resting on her chin while you pump into her warm mouth. Once your dick is thoroughly coated in her spit, you pull out and slap her in the face with it again. Her face is now a wet mess of saliva. You grab your dick and plunge into her mouth again. You pump a few more times, then pull out and rub your cock all over her face once more. Then you sit back on her breasts and admire your work.

Rachel is coughing and gasping, her face is a total mess of spit and matted hair. You roll off her for a second, standing next to her bed. She reaches up to wipe off her face and you stop her.
"No, leave it, I like you messy."
You twist her arm as she struggles and she turns on her side, facing away from you.
"Haha, I can work with that."
You grab her panties and yank them down. Then you jump into the bed beside her and rub your dick along the crack of her ass.

"Now, which hole first, babe?"
Rachel now realizes what you mean and bucks against you.
"No, no, stop!", she pleads.
You reach around her, pinning her arms and grabbing her tits in your hands. You lean your head in and whisper into her ear.
"I think I'd like your pussy first."
She thrashes against you, but can't get out of your hold.

Once she calms down a bit. you let go of one of her tits and line your dick up. You tease her pussy lips with the head of your cock and then slowly begin sinking into your little sister. Rachel begins to whimper and cry as your cock plunges deeper into her depths. Finally, your hips slap against her ass and you are fully inside her.
"Damn, you're tight!"
You start thrusting into her, slowly at first, but picking up more speed. Soon, you hear nothing but her cries and the slapping of your thighs against her ass. Each time you hit bottom, you watch her ass cheek ripple from your thrust.
"UGH, YEAH!"
Your bucking becomes harder and faster and your grip on Rachel becomes stronger as you hold on for leverage. You pound into her from behind again and again. You reach up to her head and pull back her hair so you can see her face. Her eyes are squeezed shut and she's clearly grimacing. But, she's also moaning now and no longer crying. You lean in and kiss her cheek and then her neck. You nibble on her neck and then reach a hand up and grab her throat. She lets out a low moan. You then take a firm grip on her hair and arch her neck back. Her mouth flies open and she lets out an erotic groan.
"That's it, sis, learn to love it."

You reach back down and grab her hip and thrust inside her roughly. Your sister's pussy feels amazing. And that's when you get another idea ...
