I'm a guy who has his favorite girlfriend, and I can't help but stare at big tits. It's instinctual. But my girlfriend always catches me doing it. Then she gets mad. But it's not just that she gets mad. She gets incredibly intense and horny using jealousy as an aphrodisiac. She sucks me dry until I've shot every last drop, then tortures my nipples with a mean face. Against her jealousy assault, my useless dick always gives in.
