Ryota is staying at his aunt's house to attend university in Tokyo. Although it was only for a limited time while she was at university, she was happy enough just to be able to spend time with her aunt, her first love. However, the more happy days go on, the more I start to feel unsatisfied. I want to have more contact with my aunt and have a closer relationship with her. Ryota, hungry for unsatisfied desires, attempts an underwear job in his aunt's freshly taken off panties...but unfortunately, his aunt catches him...
