Kenta, Fumie's son, has run away from home. Raised in a single-parent household, he struggled under his mother's strict upbringing. When he confides in his close friends, one heads outside while the other stays behind. Overwhelmed with shock, Fumie collapses under the emotional pressure in front of her friends. Seeing her unconscious face, one of them loses control and assaults her. Though Fumie resists at first, she's seduced by the sensation of a young, firm cock—something she hasn't felt in years—and awakens to pleasure once more. As thanks, she invites the other friend in. And now, this double seduction begins.
