Due to doing a lot of housework, Akari's back sometimes hurts severely. Her husband noticed this and was very worried about her, so he accidentally saw a flyer advertising in-home massage therapy services, and he encouraged her to give it a try. Akari followed her husband's advice and called the phone number on the flyer. Little did they know, Akari had caught the attention of a wicked man, who was the one who left the flyer there. When he arrived at the house, he used his skilled techniques to stimulate Akari's sensitive parts, causing her arousal to peak. Akari's husband was busy with work, and his sexual abilities were not great, making Akari's body even more sensitive. He progressed further, first by caressing her body, then directly touching her round, firm breasts, and eventually inserting his fingers into her vagina! The arousal made Akari lose her senses, allowing him to insert his penis into her mouth, using a 'massage stick' to 'massage inside her vagina.' Akari even let him ejaculate inside her uterus multiple times! He also continuously used various lotions and scents that he believed were for massage purposes with her. But when she was applied and smelled those lotions and scents, her body became even more restless, she no longer knew anything, just wanting him to fuck her, to make her climax, even if her husband returned and discovered everything...
