Tie him down face up on the bed. Play with him but don't let him cum. Keep this up until he's begging you. Then see how much he really wants it by sitting on his face and making him lick and suck you to climax. While he's doing that, pay just enough attention to him to keep him nice and hard. If he pleases you then you can reward him. Hopefully he won't.

Something else you can try sometime is blindfold him, use some silly putty in his ears to block out sound, and then put some of those shooting ear muffs on him. Now, all the sensations he gets are what you want him to have.

Strip him, tie his hands behind him around the kitchen table leg and eat dinner. Once in awhile you can reach down and feed him. Make sure he cleans your fingers when you're through feeding him.

If he has a lot of hair on his body, use some nair and get rid of all his body hair.

Foot worship is nice too. While you have him tied down "let" him suck each of your toes. Don't hurry. You're in control and with him being tied up he's not going anywhere.

Lot's of other things you can do with candles, clothespins, etc.
