And with that I stood up and lined my dick up with her asshole. I then began to push, she was so tight. I could only get about 3 inches in when she sa...d, “It hurts so good Trev, keep going.” She then started to push her ass back onto my dick. I then began to move in and out of her beautiful ass, I could only get it in about 4 inches, but with each thrust, I was able to go a little bit deeper.“Your big dick fills my tiny little ass hole up.” She told me, “I want it all right now.” She moaned.. His cum lubricated my shaft and a moment later I squirted my cream too.A week later I visited Paul’s house. His bedroom was in the basement of his family’s modest home. The walls were painted concrete but there was a thick carpet on the floor and the furnishings were nice. Paul and I had agreed to get together for another round of “Rubbing Wieners”.We both undressed and stood facing each other this time. Again we began to jerk off. Soon I had Paul’s cock in one hand and my own in the other. His. Clayton couldn't see who was talking because he was doubled up in pain.The second voice was even more threatening. "We're gonna fuck your asshole and if you don't wanna cooperate, we'll beat the shit out of you and then fuck you."Clayton continued to lie on the floor, still in pain but it was starting to recede. His fright was even worse than his physical pain. He believed the two men would take turns r****g him and if he objected or tried to stop them, they would beat him half to death and. Panting they could feel the knot tied to their pussies and stuck to their dogs. The boys were well used to this and gently turned on their females so they were butt to butt and they periodically tested the knotting. Nikki loved this part because she could induce multiple orgasms by rocking on the knot. It seemed uncanny to her that being knotted seemed to bump onto her g-spot with regularity.When the knots finally subsided sufficiently, the dogs separated from their human females. Both women.
