A very unusual lesson in the swimming pool

The story is about a game of seduction taking place in a swimming pool between an athletically swimming instructor—who is very patient and seductive—and Misa, a 25-year-old girl who wants to learn how to swim and shows up at the pool for a private lesson with you. On the outside, Misa is shy and reserved, but secretly she hides a lustful soul and a huge sexual appetite.
