A Simple Fucking

You look down at your cock and see that, although it's hard, it's not nearly as hard as you thought it would be. Then you remember that, throughout the day, you've gotten a blowjob from your mother, you've fucked your sister in her pussy and twice, technically, up her ass. That's four loads in one day, which, given some days where you were particularly bored, is only about half your limit on a good day. Still, each of those loads were particularly huge given the intensely erotic nature of those orgasms. Thus, your dick and balls are all but spent.

However, seeing your sister's sleepwalking, naked, and horny body, you definitely can spare one more fucking tonight.

You slowly stroke your boner, trying to get it to full strength, as you talk to Kelly's subconscious again.

"Alright, Barbie, please get on the bed and play with that pretty pussy of yours. Make sure that fuck hole is nice and wet for me. And make sure I can hear you moan while you do it."

Kelly's body immediately heads over to the bed, crawling over it sensually, purposefully wiggling her ass at you as she heads up to your pillows. She turns around and sits, spreading her legs.

One hand goes up to knead her breasts as the other heads down to her glistening cunt. Her fingers are nimble as she pets at her lips before spreading them, giving you an intimate view of your sister. She starts moving her finger tips along her pussy, stroking at her hole, flicking at her clit.

You shudder and stroke your dick a little. You put the MCR on and make sure your cock reappears exactly where it's supposed to be. You're not going to risk getting your sister pregnant and, since you don't have condoms at the moment, the MCR will due. Hell, maybe you'll never need condoms again.

You watch as Kelly's body plays with her pussy and she moans and groans a little. Her body writhes a little. She starts to pant. You can hear the squelching of her pussy as she starts to vigorously finger herself.

"Fuck," you say, getting rock hard in moments. "Okay, Barbie, get on your knees. I am fucking you like the bitch that woman who usually controls your body is."

She gets up and crawls over to the edge of the bed. She sticks her ass out and wiggles it at you.

You smirk and go up behind her.

"Naughty thing, wiggling that perky, round ass at me."

This only serves to make her wiggle it more.

You give her butt a loud spank. She jumps a little but moans as well.

Without hesitation, you move behind her and shove your cock into her waiting, wet pussy all the way up to the base. You feel Kelly's body give a shudder while you let out your own moan.

As soon as your dick is sheathed in your sister's pussy, your animal instincts take over. All the teasing, all the mind games, fly away and there is nothing left but lust.

You immediately start fucking her, thrusting and grinding into Kelly's tight and eager pussy. You grasp at her ass as you do, gripping it, pawing it, kneading it, and, of course, smacking it.

You listen to your sister moaning and groaning. You can't decide if the fact that her actual conscious mind is completely knocked out is making this sexier or a little disappointing.

You keep fucking your sister and, as you've cum a few times today already, your stamina at the moment is pretty high. Your sister has a chance to cum more than once, squeezing your dick as if clinging for dear life.

Finally, you can't take it. "I'm going to cum, barbie. Prepare that pussy for a nice, hot load."

She moans and thrusts back against you. You fill your sister's cunt with your cum, draining every single ounce out left in your balls.

You slip out and sit next to her. You slip the MCR off and your dick is squeaky clean. You glance at your sister's pussy and, miraculously, the fresh load you just pumped into her is gone.

Convenient. You bring the MCR to your lips and give it a kiss. "This is the best fucking purchase I've ever made."

You glance at Kelly's still quivering body and contemplate what you should do next.
