Locking your cock isn't enough, I have to taunt you with my words and tease you with my body to ensure you're fully fucked. I love watching you become frustrated, leaking through your cage while I demand you grab and squeeze your balls. Serving me has become your only purpose, and being degraded and humiliated has become your greatest pleasure. Chastity isn't a punishment if it makes Mistress hot and horny watching you writhe in a pool of your own precut for me. Glue the lock shut and hand over the spare key, time to plunge into everlasting chastity.
