Miu runs an inn with her husband. After making a mistake with a group of older male guests, the young proprietress is summoned to join their evening drinks as an apology. Their vulgar party turns sexual, and they treat her like a hired hostess—stroking the legs beneath her kimono, licking her, and reaching between her thighs. Exhaustion, pent-up desire, and alcohol dull her judgment until she finally accepts the older men's thick cocks, and the creampie service continues even after morning arrives.
