Naive and curious, a young man's world is turned upside down when his girlfriend and her best friend invite two more friends over for a "sleepover." The girls, all lesbians, waste no time in stripping down and exploring each other's bodies, their moans filling the house. The boyfriend, initially shocked, is soon hard as he watches the foursome engage in passionate kissing, fingering, and scissoring. He tries to join in, but the girls push him down, telling him to watch as they pleasure each other. They tease him with blowjobs and handjobs, but refuse to let him cum, leaving him frustrated and humiliated.
