I love testing your obedience, especially when it comes to the one thing you love most; your masturbation sessions with me. If I'm going to let you stroke for me, you're going to do it my way and I'm going to get something out of it. I always do. I know how weak you are for my snaps because I've been programming your dick to twitch for them. Today I'll take that a step further while pushing your dick to the edge over and over again, making it suffer for me the way a good wank slave's cock should. It's going to feel so good to build up that orgasm and blow right when I suddenly snap... and if you don't, you'll have to edge for me all over again!
