Cool Oneesan Has a Problem That I Can't Tell Anyone

Kasumi Miyafuji, a cool and taciturn older girl who's coaching the Swimming Club, has a problem that she can't tell anyone, regarding the care and grooming of her private parts. Just as Kasumi was worrying about it, a younger boy who can help with that specific problem fell into her lap. This calm, collected and quiet boy is immediately asked by her club members to take care of her pubic hair problem at her house, but with his handling he unintentionally arouses her and she climaxes. The boy is aroused at the sight of her climaxing. Neither of them can keep holding back their sexual desires... This is Muteki Soda's first original doujinshi. (Source: DMM)
