Yuri-san is a nurse at a university hospital in Tokyo. The first time, she kisses him greedily, pistoning while enjoying the feeling of her entwined folds of flesh, and ejaculates on his tongue with a premature ejaculation. The second time, she makes the M-man, whose entire body is an erogenous zone, ejaculate unexpectedly in a cowgirl position. For the third time, she makes him cum with a vibrator until he faints, then she cums in his mouth.
