i am bad at coming up with punishments. my sub masturbated after i specifically told him not to (only two days after i last gave him an orgasm!). for a punishment, i handcuffed his right hand behind his back for a few hours (till we had to go out) but this was very minor and he seemed merely amused instead of uncomfortable. what would you do? i'm really legitimately upset about this; it's the THIRD time he's done it.
