In a low security prison I got it on with a DL BBC. We started working out together in the cell, then we'd play by or go to the yard to lift, I was about 190 him 240. we showered after. One day in our cell alone he asked me if I wanted to get down on it, I almost cum right there, he sat on the side and pulled his pants down and out sprang a 9 inch HARD BLACK DICK.
