I have a challenge for you. I want you to enter into a chastity contract with me. This isn't normal lock and key chastity, this type of chastity requires much for trust. I'm talking about mental chastity. I want you to give your chastity to me for one whole week. Do you think you could even go that long? Don't worry I'll give you some allowances, but no cumming at all for one week.
It's time for you to do something for someone other than yourself for once. You will do this for me, do you understand?
