Rino, an obedient housewife, lies to her husband, saying she's going on a trip with a childhood friend, but instead embarks on an adulterous getaway. Given her naturally masochistic nature, she is fitted with a leather kikkou-shibari harness and forced to wander the inn, enduring face-fucking and forced fingering everywhere. As other guests and staff pass by, the thrill and the deep stimulation in her throat cause her to vomit gastric juices while wearing an expression of ecstasy. She accepts aroused cocks in the open-air baths and throughout the inn, with semen being released inside her rooms.
