Chastity In Exchange For Ass Worship

Ill let you worship my perfect ass, sure.. But just like any good boy knows, for the reward, youll have to earn it. What would you do just to see? If I got one inch closer, would you give me another week of chastity? Soon youll be able to smell it, certainly thats two weeks of chastty. How far will it go? One month? Three? Six?
