Climaxing Following Chastity

My keyholder decides when and for how long to release me. Also if for just teasing me and locking me back up or leting me have a normal orgasm. But she has also come up with a new option. She sits on the coch or chair fully dressed, I am naked and kneeling beside her. She puts her hand down (hard to explain) like if you make a fist, then slowly open it enough for me to put my erection into. She then ignores me and watches tv. If I want to cum, it is my jub to make love to her hand, moving in an out, slow or fast, pumping my hips around for the right feeling. As my speed increases and my breath quickens, she pays no attention, it’s as if she wasn’t there or did not exist. Finally I can take no more and shoot my load. It is my job to clean it up off her hand and the floor. She then speaks, “How does it feel to have to make love to my hand and not my vagina? Slave boy must have been really horny, to do this while I ignore you!” I am then locked back into my chastity belt. So this is in between being teased and not allowed to cum, and sharing a great orgasm with her as she attends to my needs. For some reason it drives me crazy, I can’t explain how controlled I feel and how I love it and long for it to happen again. Has anyone out there tried this, or is it just one of her mind games she plays? Please I would like to hear your comments. Thank you.
