Zariah Aura's character, Marie, assumes she's alone in the house and decides to indulge in some private self-pleasure on the living room sofa, using a wireless anal vibrator to heighten her sensations. But unexpectedly, her roommate Tomie Tang's Roberta returns home with her lover Nicole Kitt's Gwen! Marie scrambles to her bedroom, inadvertently leaving the control device behind. As Roberta and Gwen settle in and start passionately kissing and groping each other on the couch, they're unaware of the hidden remote tucked into the cushions, which they accidentally activate repeatedly, causing Marie's vibrator to pulse with escalating force, sending waves of intense arousal through her body. Overcome with desire, Marie finally crawls back into the living room to timidly request the remote. Once Roberta and Gwen grasp the erotic mishap, they express regret, but Marie's overwhelming horniness swiftly transforms the encounter into a steamy threesome filled with mutual exploration and climax.
