"Why are you doing this, Yuuichi? Stop it!" Yuki struggled desperately as she was pinned down by her son's friend. But his words, "You're lonely, aren't you? Let me comfort you," echoed in her mind, slowly stirring her emotions. Her husband was constantly busy with work, often staying out overnight, and even when he came home, they rarely saw each other. Lately, Yuki had been relieving her loneliness through masturbation. Yuuichi had noticed her secret, and his arousal became uncontrollable. She knew getting caught by her husband or son would be disastrous. Yet, her body gradually ceased resisting, beginning to respond to his advances.
