Oh my...you look like you're getting close.
Go ahead, bring yourself to the edge and hold it for me.
Did you decide? Good boy or bad boy?
I can't hear you?
If you're a bad boy and can't hold it any longer, then go just over the edge and ruin your orgasm for me...THEN LEAVE!
If you're a good "obedient" boy who doesn't cum until he's been given permission, then you may continue...
