Finally when she has had enough, she pushes you off of her, and says with a laugh:
"God, I can see why the girls enjoy you so much! You get super excited, but you can't cum unless we trigger your orgasm, can you?"
You are nearly crying, and just nod your head. You protest that she promised!
"I know, dear," she says, still smiling. "But I only promised to make love with you, not to give you an orgasm..."
You protest that she's being cruel.
