Struggling to make ends meet, a dirt-poor boyfriend agrees to a taboo threesome with his nympho girlfriend and her attractive ex. In a seedy motel room, the ex-girlfriend, hungry for revenge and cash, takes the lead. She sucks her former lover's cock with fervor, gagging on his length while her current partner watches, torn between jealousy and desperation. The ex-girlfriend then rides her ex's cock, moaning loudly as she's pounded, while her boyfriend masturbates, adding to the humiliation and arousal.
