Rin, a high school girl, encounters sudden downpours every time she goes out. Today, she boards the train completely soaked, but a male passenger stares at her breasts, which are visible through her bra, and then starts rubbing her ass at the door. With nowhere to run, Rin has his fingers thrust into her panties, and when her clit is stimulated, she squirts a huge amount of juice onto the floor. After that, the two get off at the next station and begin a hard piston-like cowgirl ride in a public toilet stall, keeping their voices down, but they can't drown out the sound of her juices splashing everywhere...
