Collaborative sex stories let us write the plot together

(Medical Experiments, continued by Human_Google...)

Nothing seems to have happened and the nurse looks very disappointed by that. You wonder if you need to do something and concentrate hard on something, closing your eyes.

“Oh my god!” you hear the nurse exclaim.

You open your eyes and standing beside you is another you, but completely naked. Your mouth opens in shock.

“Did I just clone myself?” you ask. Nurse Jenny nods, she’s as shocked as you.

Your naked clone looks from you to the nurse, then points at Jenny and says to you, “Can I fuck her?”

You’re taken aback by his request. You look down as his penis hardens. You eye the nurse, her mouth agape, and realize she’s damn sexy. This could be fun. “Sure,” you say to your clone, grinning.

“What?” Jenny protests. “Fuck n-” she can’t finish her sentence because your clone tackles her down and sticks his dick into her mouth. She gags on it as your clone looms over her in push up position.

You feel your penis getting harder. This is so hot. You can’t resist it any more and take off your pants to let your penis out. You kneel by Jenny and force her hand around your dick as your clone continues to face-fuck her. You help her stroke it and eventually she does it with your aid.

Your clone forces her up onto her knees and pulls his dick out of her mouth — drool spilling out of the corners of her mouth. Now that she’s up, you get a good look at her ass even through her coat. You push the coat up and rip off her pants to free her plump ass.

“What’re you doing?” she screams as your clone pulls his dick out of her mouth. “Get away from my ass!”

“Did you say ‘get into my ass, Steve?’ ” you say, smirking wide. “It’ll be my pleasure, Jenny.”

She tries to say something but your clone sticks his dick in her mouth again as you thrust into her tight asshole. You grab her legs and wrap them around your waist. She’s skewered between you and your clone, her tits drooping down.

You smash into the nurse’s ass harder and your clone fucks her face with more vigor when there’s a knock at the door. Doctor Mandy walks in.

“Jenny, how’d the test go-” she cuts herself off when she sees her nurse spit-roasted between you and your clone. Jenny flutters a begging eye at the doctor.

You and your clone pull out at the same time letting the nurse drop to the floor. You pick her up and hug her from behind, your dick rubbing her clit and your hands squeezing her tits.

“Oh the experiment’s going quite well so far, doctor,” you say as Jenny moans to your touch. “She’s really enjoying it, aren’t you?”

“Yes, Steve,” Jenny says weakly. You feed her three of your fingers.

“Care to see just how well it’s going?” you ask the doctor.

Doctor Mandy backs up but your clone shuts the door behind her.

“Can I fuck her?” your clone asks, grabbing the doctor’s ass.
