After cheating on her husband and going on a date with her lover, Yuu Hironaka heads to a hot spring to slowly relax. However, relaxation proves impossible. He approaches her, kissing her deeply while groping her breasts and stimulating her lower body. She can't resist. She gives him a blowjob with her hands guiding his cock, then he thrusts inside her. She allows creampie after creampie, smiling with satisfaction. Finally, she pees in a graceful arc, letting him watch her pissing.
