Blue Balls

You know what this is? An instrument of torment. Today I want you to destroy your balls for me. We'll turn them blue. Lie down before me, good boy. Now grab a rope and follow my instructions. [...] Are you ready? 1,2,3 strokes on your balls. Good boy, good boy. No, you can't touch yourself. I can see you! Don't touch yourself! You ask me if you can cum?...
