We, Lady Blackdiamoond and Lady Aurelia, are training our slave today to make sure he only cums when we want him to. He’s supposed to last at least 10 minutes and present us with a nice, hard cock. So he kneels between us and gets to jerk off. But he messes it up pretty badly at first, the clueless loser can't even get his dick fully hard. Yet you can tell just how horny he really is. But with a little help from us, using our fingernails on his nipples, things get noticeably better, and just as a good slave should, he obeys our command and licks everything off the floor at the end.
