Yuichi, who had been staying at the Nakano couple's house during his uncle's long business trip, was nearing the end of his stay. It was about time he found a new place to live... But living alone with his aunt Sayo, whom he secretly admired, made Yuichi ecstatic. His feelings for Sayo grew stronger each day, and despite knowing it was wrong, he would use her used underwear to pleasure himself. One day, while masturbating as usual, he was caught by Sayo.
