The long-established hot spring inn "Kyonyoku-kan" has been secretly popular among honeymooners since old times. The inn is run by a beautiful and busty young innkeeper, Naoko. It appears to be an ordinary hot spring inn, but when a newlywed couple visits, the husband is served dishes made with natural aphrodisiacs and bathed in hot springs that enhance erectile function, putting him in a fully erect state. The wife is given food laced with sleeping pills to make her fall asleep. Then, taking advantage of the wife's slumber, Naoko enjoys the first night with the husband, extracting semen from him until he ejaculates, offering the ultimate hospitality by demanding internal ejaculation.
