The boyfriend, his eyes wide with a cocktail of jealousy and lust, watches as the stranger's hands tangle in his girlfriend's hair, guiding her head up and down his shaft. The room is filled with the wet sounds of her mouth and the stranger's grunts, the air thick with the scent of sex and desperation. As the stranger's cock grows harder, the boyfriend's own begins to tent his pants, a testament to the perverse thrill of watching his girlfriend being used for money.
