A group of close friends, feeling adventurous, decide to experiment with sleep sex. After a night of heavy drinking and late-night confessions, they retire to their rooms, eager to explore their newfound desires. The stepbrothers, drunk and horny, stumble upon their sleepwalking sisters, masturbating in their beds. Intrigued and turned on, they join them, their hands exploring each other's bodies in the dim moonlight. The sisters, half-awake, respond to their touch, their moans filling the silent house. As dawn breaks, they wake up, their bodies entwined, their minds racing with the memories of their shared, taboo experience.
