Crystal and Melissa and I had talked about it earlier. Both Crystal and Melissa liked to get their boyfriends extra "fired up" (as Melissa put it) by encouraging them to have sexual dreams.
So that night, as Tom laid next to me, trying to sleep off three days of intense teasing, I decided to try out their theories. So every once in a while, when I would wake up a bit, I very gently stroked Tom's cock until his breathing got more rapid and I could see his eyes moving.
This seemed to have powerfully encouraged Tom's sexual dreaming...
