The central question here is, "You can dish it, but can you take it too?" He's going to get to practice a little tease and denial on you this time! So to start, after a little foreplay, have him "warm you up," and bring you up to the edge of orgasm. You'll need to tell him when you need him to stop, of course. Then, he'll give you a little rest, and then eventually edge you again. You can tell him how he has to do it (hand, mouth, vibe, whatever), or it can be up to him. Also, he'll need to keep track of how many times he "Edged" you. You might want to put a time limit on it so he doesn't just go on forever! Maybe 5 minutes?
