Sakai Mio is a lonely junior colleague who has just moved to Tokyo. A drunken sleepover begins, and the moment I take off her clothes, I see her voluptuous breasts, out of proportion to her slim frame. The shocking contrast blows away my rationality, and I continue to desire her all night. The situation of being the only person I can rely on in this new city transforms her resistance into sweet moans. The warmth of our bodies overlaps over and over again until the morning, her soft breasts swaying, and the vivid sounds of water echo through the small room.
