Kaori has long supported her daughter and her childhood friend's relationship. She was happy they had finally become lovers. After sharing dinner together, they discussed spending the night, and Kaori felt touched. When her daughter's room grew quiet, her heart suddenly started racing. Suddenly, her daughter ran outside in tears. Surprised, Kaori asked the boy what happened, and he confessed that their first time hadn't gone well. Right there, he revealed his erect crotch, took Kaori's hand, and began guiding it to touch him. Conflicted, Kaori still found herself offering to teach him how to succeed, and as she did, he moved in and embraced her body.
