Please Me By Hurting Yourself

I want to see you in so much pain that nothing exists in the entire world but you and I. You're going to have to do some of this yourself, get creative. You think you're so obedient, so eager to do whatever I tell you to. You know you could never please me sexually, this is how you please me--by hurting yourself. I want you to prove yourself to me. Now stick something up your ass. Something on the larger side, no warm-up. Now, to your balls... (For best viewing experience, you'll want a two dildos, a vibrator, a shoe, and some string or a ribbon. A shoelace, perhaps?)
