Synopsis
The lewd sisters' seduction diary targeting dad's well-built protégé! Oppa, want to work out in our room?

Jin-woo, a student at a college of physical education, visits the home of Min-cheol, his former high school P.E. teacher, who lives outside the city, during his vacation. Min-cheol warmly welcomes Jin-woo along with his two daughters: Soo-hyeon, an office worker, and Soo-hee, who has just become a college student. A few days later, Min-cheol suddenly has to leave on a business trip to attend an unexpected regional seminar. Apologizing to Jin-woo, he heads out, leaving his former student alone with his daughters. While their father is away, the sisters — lonely from living in the countryside without a man — begin their secret seduction. That evening, Soo-hyeon comes home late and pretends to be drunk. She vents to Jin-woo about the hardships of working life, complains, and says it has been a long time since she last met a man. She then begins to seduce him, leading to sex. The next day, after Jin-woo returns from working out, Soo-hee approaches him. She is actually Jin-woo's junior from high school, though he had never been interested in her before. Saying that her dad is a hassle and doesn't really teach her much about fitness, she asks him about stretching techniques and similar topics, and casual physical contact naturally follows. When that doesn't go as planned, she claims she saw him with her sister and threatens him, using it to seduce him. After having sex with Soo-hee, Jin-woo ends up having sex with the sisters alternately.
