Look at you, on the floor stroking for me. Such a filthy slut. If I were there, I'd reach over and stroke your chest and twist and play with your nipples. I guess I'll just have to make you do it. But I can't decide whether I want you to have pleasure or pain...
Let's play another chance game. Roll a die. If you get an even number, be nice to them and pleasure your chest. Odd number, hurt them.
