You sent the key to your chastity belt to your mistress as a mark of trust? You failed bad. What did you think would she do with it? You're completely at her mercy now and have to follow her direction, fulfill every single command - no matter if you want it or not, you HAVE to! Except you don't want to see your tiny, useless dick ever again.. she will tease you 'til your brain is fucked up and lost beyond recall!
I can do whatever I'd like to turn you on but you can't do anything. You just have to sit and watch as your cock gets hard. Your masturbation addiction is becoming too much, you need to learn to control it. Watch my hot body in a thong as I tell you that you can't touch me. You can look at me all you'd like but no touching allowed!
