Collaborative sex stories let us write the plot together
(Medical Experiments, continued by Nillus...)
As you feel your impending orgasm, you have a sudden flash of clear judgment and decide against possibly getting the slutty nurse pregnant. You pull out of her and she immediately drops off the desk onto her knees and takes your cock into her mouth. Her tongue swirling all over your massively engorged cock-head sends you over the edge. You fill her mouth with copious amounts of cum, and Jenny has trouble swallowing it all, and some ends up dribbling down her face into her perky tits. After she finishes sucking you dry she pulls your cock out of her mouth and starts jacking you off.
“How’d you know I fucking love the taste of cum?” Nurse Jenny asks.
“Heh, lucky guess?” you reply.
Jenny giggles as she realizes you are still hard.
“So, do you wanna go again? Or should I call the doctor?” she asks.
Your cock is really starting to hurt. On the other hand, maybe another go at the nurse could fix it.
