I wear a CB 6000 and have done for a few months now. I wear the 2nd largest ring and smallest spacer as the middle ring gave me an awful lot of pain at night. I am in chastity for around 20 days then given release only to be locked back up an hour later. Iif I work the tube or pull the base ring I can become aroused. I am staying chaste because I am frightful of my Mistress finding out as she knows how much I produce after 20 days. Is there anything I can do to become fully chaste and at the mercy of my keyholder?
