You're mistress knew all she ever had to do was talk about touching you and you would get hard and feel the endless frustration of the cage, however, on certain days she would take down your panties and rub herself against you cage. It was almost enough
You always thought you had problems with being insensitive down there, however, it would appear you just jerked off too much and lost sensitivity, 2 months in chastity fixed that.
When your partner suggested you try some bondage to spice things up, you never imaged it would start with 3 weeks of chastity followed by a shibari session ending in free use for all your partner's friends.
