Ai is in love with her fellow classmate and young genius Yuji Shimohara. After hearing Yuji has a fetish for enormous "super boobs" she asks him to help her breasts grow in hopes he'll fall for her. Thanks to Yuji's high concept science works but only for her to realize that living with breasts of that size is difficult. How will she live a daily life with breasts so big and what will happen if Yuji want's them bigger?
- A girl asking for enormous breasts just to please you is rather romantic. My favorite topic for breast expansion isn't even sexual but rather the daily life aspects of having gigantic breasts. More hentai should explore this more.
I like this one not just because it's damn hot, but because kakuu actually shows his interest in Japanese history by going out of his way to write paragraphs of school history lectures.
