Ofuro de...♥

Childhood friends Kazuki and Mai have been together for as long as they can remember. As Kazuki's parents are out on vacation, the honest and cheerful Mai is living in his house to look after him. One day, while he is taking a bath, she barges into the bathroom and wishes to join him, which he goes along with. Though he has considered Mai a friend for many years, Kazuki finds himself aroused by her naked body, and she does not seem to mind that.
