was coming up on the forth when suddenly I heard the real Derick say, "Oh fuck, I'm going to cum."

I looked up and he was moving toward my desk with his cock in his hand. The next thing I knew, he was cumming all over my desk, spraying my computer monitor again and making a huge mess. I guess when I put the toy in my ass he lost it. It must have been too much for him and he was too close to stop. When he finished I just stared at him.
