AGMX-031 Reincarnated as an M Male ~ I’ll become an M male in front of you ~

If both men and women claim to be S, the stronger one will be S and the weaker one will be M. What will happen to the man who says he is S when he is forced to play as M man? At first it was not accepted, but the man fell into M due to a super strong slut act. Nipple torture, leg job, size stop. He undergoes various humiliations, finally begs for ejaculation, and realizes that he has become a M man.
