The father, known as the strict advisor of the girls' volleyball club, is stricter than most when coaching his daughter, who is also the club's captain. However, when he returns home, he treats his daughter like a completely different person. He gently massages every inch of her body, which has been overworked in club activities. The father and daughter share skinship, touching each other like lovers. Sexual intercourse has become a normal part of the daily life of a father and daughter, and they are connected by pleasure.
