Yamada, first name withheld, is a 15-year-old girl who has just entered Takizawa High School. Easily considered exceptionally beautiful, she has only one problem with her own body, she thinks her ****** looks weird and is very self-conscious about it.
Upon entering high school, her dream was to have casual *** with 100 men but therein lies the problem, she believes an experienced partner will tease her about the way her ****** looks or simply the fact that she's a ******. She stumbles upon the solution in the form of Kosuda Takashi, a fellow ******, whom she believes will help ease the transition to more experienced partners.
There's only one small problem, Yamada doesn't know anything about *** or the ancient art of seduction...
