Mariko's husband is on a long business trip, and she lives with her son, Kazuya. She becomes attached to her son's friend Atsushi, who she recently made, but... Atsushi, a single-parent family starving for her mother's love, confronts her with his desires that exceed her love, and forcibly pushes her down. As he greedily plays with her body repeatedly, Mariko unconsciously enjoys the pleasure she hasn't felt in a long time. Youthful and vigorous flesh that her husband doesn't have.
