You and your friend Bettie are hanging out when you start talking about your weekends. You tell her that you went to a strip club and she laughs.

"Did you cum in your pants?" she teases. You blush, insisting that you didn't. She doesn't believe you. She says she knows you well enough to know that a hot girl grinding on your boner, even through layers of fabric, would make you jizz. You insist that nothing like that happened! So, she proposes a bet: if you can stand her grinding and dry humping you for ten minutes without cumming in your pants, then you win $100. Simple, right?
