Bound and forced to watch, the cuckold's eyes widen as his partner, a confident femdom, welcomes a total stranger into their bedroom. She straddles the anonymous man's thick cock, her hips undulating as she takes him deep. The cuckold's humiliation grows with each thrust, his protests muffled by the gag in his mouth. The stranger, unfazed, grunts in pleasure, his hands gripping the femdom's hips, pulling her closer. The room fills with the sound of their flesh slapping together, the stranger's grunts, and the cuckold's muffled cries.
