Mikako has decided to move to Hokkaido because of her husband's work. My best friend Junko says she will have a farewell party, so I decided to stay at her house. Junko's son, Naoto, came home and had a good time together when the flowers were blooming in the old story. Naoto, who was fascinated by Mikako's adult sex appeal, peeks at Mikako taking off her clothes at the dressing room to take a bath that night. Mikako, who noticed her gaze, helped with the drunkenness of alcohol and began to gently seduce her in her usual beige underwear.
