Bound and helpless, the bisexual sub surrenders to their mistress's whims. She teases them relentlessly with a monster cock, slapping it against their face and body, making them salivate and beg for release. The femdom torments them with a vibrator, edging them repeatedly until they're a quivering mess. Finally, she mounts them, riding the giant cock with abandon, forcing the sub to cum violently, their body convulsing as they're used for their mistress's pleasure.
