"What's wrong, Yuichi? Stop it!" Yuki was pushed down by her son's friend Yuichi and desperately resisted. But at the same time, Yuichi's words "You're lonely, aren't you? I'll comfort you" echoed in her head. Her busy husband often stays over, and she has no choice but to comfort herself by masturbating. Peeking at Yuki like that, Yuichi became excited. If her husband or son were to find out, it would be a disaster. Even as she thought this, Yuki's body weakened its resistance.
