NFDM-437 The beauty coach of the swimming club made me ejaculate many times until the balls became empty. Saryu Usui

Mr. Tanaka, who joined the swimming club with no members at all, was enthusiastic about being able to monopolize the guidance of the beautiful coach, but the coach's competitive swimming suit is so sexy that his lower body is unintentionally swollen. The coach finds it and says, ``I can't teach you while you're stupid'', and I'm forced to ejaculate many times.
