Natsuki is a cute, busty subordinate secretly in love with her serious, uptight department manager. Sharing a room at an inn during a business trip, she gets tipsy, presses her G-cup tits against him, and teases him with slips from her braless robe. His panicked protests about workplace rules only amuse her, and once he loses control he grabs and sucks her breasts. Thrilled by the teasing, she mounts his cock for hard pile-driver sex, gives him a titjob in the mixed bath, and keeps fucking him with a smile until morning, taking creampie after creampie without letting his cock rest.
