Your chastity key
This mistress has a key around her neck. She makes you horny with her sexy dress. You will love her and you would like to sniff her panty but it is not allowed to you. But there is no chance for you to jerk off because she has the key of your chastity belt. This is your fault. Why have you give her that key. Now she keeps you in chastity and nobody knows how long it will be.
