As ineedfemaleslave's dare doesn't really makes any sense, I'll give Deracination one, that really is about his ass for a week...

First of, whenever you're alone, you are wearing a buttplug, and only a buttplug. From your collection I'd guess the Aces of spades would be best.
Only take it out when you need to go to the toilet.

Then, whenever you want to masturbate, change your aces of spades to the vibrating one. Leave it in for 30 minutes, watching some "ass-destroy"-porn. After that you may start masturbating, but only whilst also fingerfucking your ass with at least 3 fingers. (or as many more as you can fit, if possible even the whole hand) (And if you dare, lick both hands clean after done )

Next person controlls my head for half an hour. Please be creative. ^^
