私の執事の訓練とからかい - 貞操オーガズムの否定

I am training my slave to become my butler. I own him and his cock anyways, so serving me as my butler is the next step in his commitment to me. He is kept in chastity all day long, every single day. I hold his key and only let him out one day a week for teasing and edging, and usually only one ruined orgasm a week. Today is not the day he is allowed out of chastity, but I still want to tease and torment him inside his cage. I am training him to enjoy getting tease inside his cage. I love seeing his cock get hard in his cage while I tell him what I expect of him. Three different times I use my vibrator on his caged cock, getting him closer and closer to orgasm each time. But today my butler is to be denied. Left horny, frustrated, and most importantly- Obedient. I may just unlock him once a month now that I can reward him without even taking his cage off.
