Amber Summer and Sarah Lace, stepsisters with a penchant for pushing boundaries, strut around in patriotic bikinis that barely contain their petite bodies. Anthony Pierce, their stepbrother, can't help but notice their ripe, young curves. The sisters, aware of his gaze, tease him mercilessly. The tension builds as they playfully splash water, their bikini tops threatening to slip off. Anthony's restraint snaps, and he joins them, leading to a heated, taboo threesome in the pool house.
