Happy NYC reopening day all!!!! When I began my journey 13 years ago my mistress of choice had some activities which i wanted to improve at receiving in order to please her. Specifically her favorite was ballbusting. So when i was in the shower I slapped my balls harder and harder to build up tolerance for this unique pain. It really helped me to absorb more punishment than i otherwise would have been able to handle.
So my question to both dommes and subs is what have you done to improve your abilities/capabilities in sessions?
