Unpai, who was promoted as the advisor of the swimming club. A beautiful and well-proportioned popular female teacher who is also good at taking care of people. One day, a confession from a student, Nishino, who genuinely likes Unpai-sensei. Although she thought she had politely refused, the students who resented this went on a rampage!! Forced to wear an extremely revealing swimsuit with her breasts exposed, she is violated by the superb dicks of students who are in the throes of wanting to fuck, and cumming unwillingly!! An endless creampie relay where she is defiled and fucked with semen that is too productive!!
