Adult stepson role-play: MARINA remarries an older man and builds a warm relationship with his adult son Ryota, who is close enough in age to feel more like a younger brother. Just when she believes they have become a real family, Ryota confesses that he loves her as a woman, not a mother. Shocked and conflicted, MARINA begins to see her adult stepson as a man, leaving them alone for a week with desire neither can ignore.
