[The misfortune of Yuuri Adachi, a female student who is too ignorant about sex] G cup, beautiful girl. No matter how you look at it, Yuuri only has the ability to be popular, but she does have one flaw. She is ignorant of sex, and she does not know her weapons. Never in her wildest dreams did she realize that her big breasts would drive men crazy, she continues to go to school without a bra today and tomorrow. She has a firm and transparent uniform, swimsuit, gym clothes, and even in private, her big breasts can't be stopped! She said, ``Hmmmm. Even though she says she doesn't like it, I wonder why everyone is suddenly attacking her...'' Who is Yuuri, who doesn't like it but somehow lacks a sense of sadness, perhaps because she doesn't know anything about sex? They end up being attacked. Clothed big breasts, breast fetish, breast fir, titty fuck... A work packed with big breast fetish!
