Your wife/girlfriend is waiting patiently for you to come to bed, isn't she? You told her you'd be there in a little while and she's expecting your sexual attention.. But I don't want her to have it. Your cock belongs to me. You can barely have an orgasm without thinking of me anyway, so I think I'll just ruin her chances at intercourse altogether. But let's give you a fair chance, shall we? I'm going to have you masturbate and you're going to try to make it to the end without cumming. I want you to try to not cum and try to save your load for her.. but you're going to fail. It's only a matter of minutes. Watch and stroke.. and see if you can make it through the gauntlet.
