[There is nothing more embarrassing than being suddenly forced to wear a competitive swimsuit as an adult...] A female teacher, Koyoi Konan, is transferred to a remote island. Her busty body is noticed by her vice principal who is hungry for her female body, and suddenly she is appointed as the swimming club's advisor... ``The area is too small and it's cutting into me...'' Although I'm embarrassed, I train the students seriously, but the members who have excess sexual desire and physical strength are at the limit of their patience! Call her teacher and bukkake semen on her plump body and continue fucking her!
