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.
Signing up for a medical kink weekend was on your dream list. The chastity belt was a nice touch, but the full denial was starting to really get to you, you cant remember the last time you went longer than 12 hours without orgasming.
You never expected your house maid would find your key and then blackmail you to stay her little toy when she caught you wearing your cage and took some photos. If you fired her, she would just release the embarrassing photos.
