You spot her at the party: hot, bratty, taken, and ready to argue. When you brag about your massive cock, she calls it overcompensation—you're clearly tiny. You double down, proposing a bet: back to her place to prove it. She’s adamant you’re bluffing and needs to defend her honor.
She calls her boyfriend. Reluctantly, he agrees to watch you "fail" in their bedroom. You drop your pants. Her eyes widen—you weren't lying. This is the biggest, thickest cock she's ever seen.
As you stretch her tight pussy on their bed, she tries maintaining her attitude for him, but your pornstar dick hits spots he's never reached. She starts moaning uncontrollably, forgetting he exists. "Fuck, you're so much bigger," she admits, cumming repeatedly on your shaft.
She rips the condom off, begging for your bare creampie while staring him down. He watches in horror as she worships you, realizing she’s already yours. She lost the bet, but he lost his girl—and now she’s addicted.
