X walked in as Paul was pumping my ass. I was moaning with pleasure and whimpering with pain. Paul let X watch him fuck me for what seemed like a few minutes, then he pulled out before he came. X was busy taking off his clothes, and in the interim, Paul picked up the vibrator and applied it to my clit. He wasn't going to let me come, though, he just wanted me even more heated up.
X laid down on the bed on his back and motioned for me to get on top of him. I was so hot, I felt like I was going to cum at the next touch of my clit. I got up and straddled his dick.
"Here's your second dick, slut," X said, as I slid on top of it. It felt thrilling to be fucking another guy, to have two men there, to let myself be abandoned to the pleasure. "Fuck me hard," X said as I bounced up and down on him, "harder."
I felt Paul's hand on my ass; he tipped it up. "Okay," he said. "Now this whore's going to see what it's like to have two dicks in her."
