Collaborative sex stories let us write the plot together

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

You smile as you hear your girlfriend’s friend wailing. “I’m not stopping, Monica!”

“Please, I’m begging you, it’s too big!”

You ignore her and return to relentlessly pounding Rachel’s asshole. She gives off a yelp each time your bodies collide.

You look at Monica to see her tear-stained face, still with your cum all over it, also matting her hair. Her petite little body is shaking after numerous orgasms. You finally show mercy and stop the dildo, but leave it in her.

Meanwhile Rachel is hungry for more. And your step-sister Amy might have recovered enough for round two.
