Three petite adult women who no longer find ordinary sex exciting disguise themselves with short wigs and men's underwear, then enter a men's bath wearing only towels around their waists. Their small chests help conceal them at first, and the thrill of bathing among naked men encourages them to move closer to other guests and raise the stakes. At the outdoor bath, one woman is left alone and her disguise is exposed; men surround her, grope her and penetrate her. The other two are discovered near the restroom and suffer the same fate. Their ultimate thrill ends in sex with complete strangers.
