In this erotic tale, our protagonist Shunsuke finds himself spending a week at his uncle's rural home, where he encounters his beautiful cousin Ai. She wears boyish attire and seems unphased by her revealing outfit around him. It appears that she has moved on from love, hinting at marital issues with her husband. When Shunsuke innocently asks about dating tips (leading to their hotel room encounter), he accidentally reveals his virginity. As punishment, Ai agrees to teach him about sex under one condition - they must have intercourse while fully clothed. Despite their best efforts to resist temptation, they both struggle against their desires. Will they be able to control themselves or give in to their primal urges?
