For supporting her husband... She started a home esthetic business as a supplement to their married life. A married woman named Kasumi, who uses her experience from her previous job, starts gaining customers on her own. However, she ends up performing a blowjob on a customer who pointed out that she was operating without permission. Kasumi, who doesn't want her husband to know about the whole thing, is forced to go on an onsen trip with the customer. Lying to her husband, she goes far away, and in the inn, she is fingered until her white skin turns red, and her already soaking wet pussy easily accepts the big dick.
