Someone has been a very good house slave, so I reward him by taking him out of chastity for a little bit of edging and teasing. He's been locked up for 7 straight days, so I know his cock is extremely sensitive. Almost immediately after I tell him he's not allowed to cum today, he cums anyway without my permission. Slave's cumshot is at least impressive. But his premature ejaculation is not acceptable. He gets a little post orgasm torment to take away any pleasure he had, before getting locked back up for at least one more week. This was supposed to be a very long tease and denial session. Clearly more training is needed.
