My nephew, Masaru, was allowed to stay at his aunt's house near the university he attends. Her beautiful and good-natured aunt had always been her idol. She was happy living with her aunt under one roof. One night, her drunken aunt stripped her clothes and disappeared into her bedroom. Katsu is excited by her lukewarm underwear that has been thrown off, and secretly wraps it around himself to comfort him, but unfortunately he is found by her aunt.
