Mom's friend Yuko came to stay overnight to support her son, who was competing in a national tournament. Shy and nervous upon seeing his first love after so long, Shinichi quickly fled to his room. Meanwhile, drunk and in high spirits, Yuko wandered around the house until she found Shinichi. Remembering how they used to hide together in the closet as kids, she slipped into the closet with him. Pressed closely together, she grew aroused, kissed him passionately, then whispered, "When Mommy's asleep, come to me," before leaving the room.
