Is he edging?
Sit down on the bed in front of him. Feel the tip of his cock. Is there any precum? If there is, then smear it with your fingers on your nipples. If there's not, then tell him to stroke faster!
Tell him "There is an extra rule tonight. As you wish to cum on my beautiful tits, they need to be shown the respect they deserve. Whenever i snap my fingers you are to rush from wherever you are to worship them. Kiss, suck, lick and play with them, not to hard, not to soft. If you fail to do this, the consequences will be severe. Do you understand?"
Feel his cock again, take the precum, smear on nipples....
Snap your fingers!
After he has caressed your tits, you tie his hands on his back (tight, no room to move).
Go lay down in bed, and pleasure yourself.
