Collaborative sex stories let us write the plot together

(Her Secret Fantasy, continued by Bay...)

You smirk lustfully as you look at Alex. The poor guy actually thought you would let him have your girlfriend’s pussy? Well, let’s see what he will do when he can’t walk.

You shove your dick back into his little asshole and start pounding him like an animal. He writhes underneath you out of pleasure and you take that as a cue to fuck him harder. By the time you’re done with him his asshole is gaping and leaking cum while his butt is red from your thighs slapping against it.

As you finish up the little fag you turn to your girlfriend and grin at her, perfectly showing your intentions.
