My son, Akihiro, can't hide his nervousness when he learns that his mother's junior, Saya, who is his first love, is coming. However, he is embarrassed to meet him for the first time in 10 years, so he acts unfriendly on purpose... That night, Saya, who is tipsy and in a good mood, presses her to kiss Akihiro, who doesn't talk to him. Akihiro, unable to fall asleep because of the excitement of the touch of his lips with the woman he admires, instinctively embraces Saya after taking a bath. She was frustrated with her life with her husband, and her body reacted sensitively.
