In a small, dimly lit apartment, a brother and sister, both in their late teens, find themselves alone for the first time in years. As they reminisce about old times, the atmosphere grows thick with tension. The sister, Michelle, starts toying with her hair, her eyes flickering with a newfound, unexplained hunger. Her brother, unaware of her thoughts, continues their conversation, but when he catches her staring at his crotch, the air shifts. Michelle, emboldened by her newfound desires, makes the first move, asking him if he's ever thought about them being more than just siblings. As they delve into their newfound, forbidden relationship, they discover the raw, intense pleasure of taboo incestuous love.
