Cock control is a just small piece of the puzzle. I love denying your erections. Making you weak and vulnerable. Denial is the only acceptable state for a true beta. But there's more. The longer you're in chastity, the longer I deny that penis, the more the corpus cavernosum atrophies. Like any muscle in your body, without use - it weakens. If it can't expand, it shrinks. The longer it's restricted, the smaller it gets. Locking you in that cock cage for longer and longer durations, coaxing you to buy smaller and smaller chastity devices... eventually, I can actually disappear your dick. It's not like you were using it anyway. Let's shrink it down to a little nubbin so you'd never dream of fucking another woman. It'll be too embarrassing to ever show anyone, unless it's me so I can laugh at it. I have a set of special instructions for you to be able to fulfill my wishes. My passion for disappearing beta cocklettes is so infectious, you won't be able to say anything besides, "Yes, Mistress, shrink my useless cock for life."
