"Sister will belong to someone else starting tomorrow..." The younger sister, who has a strong possessive desire for her older sister, proposes taking a bath together on the eve of her sister's wedding. As she washes her sister's body, which she hadn't seen in a while, the younger sister can no longer hold back. She restrains her struggling sister and engages in an intense kiss, caressing her entire body with her soft tongue. The sister, forced to climax multiple times, begins to move her hips vigorously on her own, both of them dissolving into forbidden incest.
