Miwa Yamamoto is a hardworking proprietress running her family's traditional inn. Seeking new excitement in their intimate life, her husband devises a special form of hospitality within the inn—using bondage to awaken Miwa's deep sense of humiliation. He begins by restraining her at the entrance, tormenting her with toys to intensify her submissive desires. His schemes grow bolder, escalating to tying her up completely and exposing her blushing, helpless body before guests enjoying themselves in the banquet hall. This extreme performance pushes her shame to the limit. Their twisted relationship deepens the atmosphere of the inn's nights, making them richer and more intense.
