A curious roommate discovers her teen roomie's secret - vibrator panties that leave nothing to the imagination. She watches, hidden, as the girl grinds on her bed, the buzzing growing louder, her moans more insistent. The teen's hand wanders, stroking her clit through the vibrating fabric, her eyes closed in ecstasy. The roommate can't resist, joining in, her own hand sliding into her pants, mimicking the teen's rhythm. When the teen finally slips off her panties, the roommate gets an eyeful, and a mouthful, as the teen turns around, noticing her voyeur for the first time.
