Yu is a receptionist at a sexually transmitted disease clinic. If such a cute girl was in the sexually transmitted disease department, men would get aroused and would not be able to get a test done. She seems to get tested regularly, so she has a great sense of chastity. But if she gets tested regularly, it makes you think... Could it be that she's been with an unspecified number of men?! But contrary to her neat and tidy appearance, she seems to be quite proactive when it comes to sex. Even when I handed her a vibrator, she smiled and reacted as if her lower body was tingling. She had a great reaction, not seeming to dislike it at all when I put the vibrator on her breasts. She said that she usually lives a reclusive life, but if she's this horny, I hope she'll go out more and give some leftovers to the men of the world.
