Takehara Hideo is a perverted high school student who has an obsession with sex. He is befriended with Kanzaki Sion, a girl living next door. Hideo wants nothing more than to have sex with her, but Sion is firm and diligent and won’t allow it.
Hideo dreams of living together with Sion and having sex with her all day long. Of course, Sion quite adamantly denies him his dream, but…… Somewhere down the road her shouting becomes mixed with moans of ecstasy.
* An uptight girl serving as a maid!
Though Sion is harsh on the protagonist, she actually thinks kindly of him. Though normally strict, she turns all mushy during sex, and gives sexual service to the protagonist! And as a maid, no less!
* Massively erotic especially because it features a maid!
She serves with her mouth, with her breasts, in bed or in the bathtub or even in the hallway! On the beach, at the shrine and even at school! While the pair lives together they go on dates to various locations, and engage in lots of different sexual activities.
* The uptight girl is ensnared by sex!
Sion flat-out denies that she is in any way a horny girl. But stubborn though she is, her body doesn’t lie, bringing her into a difficult situation.
