OL Hikaru is continuously facialized by a gang of five molesters on a commuter train. Her breasts, back, and ass are thoroughly aroused with lotion, fingers and vibrators inserted into her as she's forced onto all fours with her wrists restrained. Blindfolded and further tormented, Hikaru's back and ass are obsessively fetishized. She climaxes repeatedly using only her ass, her writhing buttocks luring viewers into a lewd ass fantasy world. An intensely charged, stimulating experience unfolds.
