Ok, now i want you to get tied up.
I want your hands in the handcuffs (if you dont have handcuffs use a sock)
I want you to tie your neck to your bed so that if you struggle too much it will begin to strangle you
I want your nipples to have the clothes pegs on them.
Connect a peice of rope between your nipple pegs and your handcuffs so that if you begin to pull your hands away too much you shall begin to suffer.
Have your balls tied with a peice of string - Connect this string to one of your ankles.
Get the vibrator and connect it to your cock in anyway you can. Turn the vibrator on.
Do not stroke that cock unless stated
