Collaborative sex stories let us write the plot together

(Medical Experiments, continued by RandomShadfan...)

While breathing in Nurse Jenny’s scent, you slide down your pants. In doing so, you learn that your dick has changed: from being a long piece of meat, it’s turned into a pink, bulbous dog-like penis.

You suddenly stand up and prod the entrance to her pussy with your dick. “I’m sorry, Jenny, but you’re too sexy to not fuck,” you apologize, not knowing if you really mean it. Before she can react, you push yourself inside her and she arches her back in surprise.

Jenny’s pussy is surprisingly tight, and although it isn’t yet fully wet you’re able to fuck her with ease. You bury yourself deep inside her and thrust fast, prompting many moans of pleasure from her. You cup her tits with your hands and play with her nipples as you thrust into her.

“Oh, God… Steve, fuck me faster, please!” she pants, howling like a bitch in heat. Her legs have wrapped themselves around your body and she’s gripping the desk like her life depends on it.
