Collaborative sex stories let us write the plot together

(Medical Experiments, continued by Anon...)

You stick your dick into the doctor’s tight pussy and move it around, swaying your waist back and forth as she stands there frozen. At first you’re enjoying it but it isn’t as fun without her reacting to it. You pull out and admire her up and down before snapping your fingers. She hops out of her stupor and looks around, scared.

“Why am I naked?” Mandy screams, blushing and trying to cover her private parts with her hands. “And why’s my pussy sore? Who are you?”

“I’m your guinea pig for today,” you day smiling at how nervous she is. “And I’m gonna fuck you hard.”

“Like hell you are!” Mandy screams and pushes you away. She reaches for the phone but you freeze her again as she’s bent over reaching for the phone. You concentrate hard and unfreeze her head and private parts. She screams, then asks with curiosity, “What did you do to me?”

You walk in front of her and lift her chin with a finger. “Your experiment lets me control time and I wanna properly thank you for that. Your lovely nurse will be next.”

Mandy looks over to Jenny who’s still frozen completely and her scientific mind overpowers her sense of danger. “That’s amazing, we’ll be rich!”

You lower her head and rub your dick against her cheek. “You can worry about all that after I’m done having my fun. Now suck it, slut.” You force Mandy’s mouth around your dick and pull hard on her hair. She moans and tries to struggle but the rest of her body is still frozen in time.

As you approach climax, you pull out your dick and ask, “Is there anywhere you don’t want me to fuck you?”

With tears in her eyes and blowing her messy hair away, Mandy says, “Just leave my ass alone.”

“Your ass it is.” You walk behind her and give her exposed butt cheeks a hard slap, causing them to redden.

“I said not my ass!” Mandy screams.

“Not up for you to decide.” You plunge into her tight asshole and grab onto her waist and completely unfreeze her. Back in control, she tries to break free from your hold but she can’t as you pound harder than you ever have into her ass.

“Tell me what you want,” you yell at her with a slap to her ass.

“I want you to fuck my ass,” Mandy finally admits. “Stick that dick in me hard, Steve, cum into my tight asshole!!”

You oblige, unloading into her. She collapses onto the ground, satisfied with the fucking. You get an idea, snap your fingers and reverse time to before you came. Mandy begs for you to come into her asshole again but you pull out and stick your dick into her mouth.

“Swallow it all, my dirty little hoe,” you day as you speed up the face-fucking until tears leak out of her eyes. This time you unload into her mouth until it’s full then pull out and spray the rest on her face.

“Yes, make me your slut, Steve!” Mandy begs as you cover her face in hot liquid and she chokes on the cum in her mouth. “Shower me with your cum, papi!”

Once she’s nicely drenched, you pick her up and freeze her midair, stretching out her arms and legs. You unfreeze her head so she knows what’s happening.

You latch onto Mandy’s big tits and hard nipples and stick three fingers into her wet pussy. Her face is still drenched in your cum as she moans to your touch.

“Fuck yes, Steve,” Mandy moans, trying to keep her head up. Her cum-covered hair is dropping down towards the floor. “Suck on my hard tits, bite into them.”

You do as she says and repeat the process with Mandy’s other tit until you’re fully satisfied you’ve repaid her enough.
