夫とふたりで経営する旅館。団体オヤジ客を相手に失態をおかした若妻女将・空は、詫びも兼ねた晩酌へ呼び出された。下品に酒を飲み散らかしては卑猥な娯楽が始まり、コンパニオンのような扱いを受ける空。着物に隠れた巨乳をまさぐられ、乳首も舐めじゃくられ、股間にまで汚い手が伸びてくる。多忙な日々の欲求不満、酔いで鈍った理性が…ついに濃厚オヤジたちの肉棒を受け入れてしまった。「あなた、ごめんなさい…」寝取られた美人妻はそれからも毎夜、中出し接待に赴くのであった。

The inn is run by the couple. The young wife and proprietress, Sora, makes a blunder with a group of older male guests and is summoned to a drinking party as an apology. After drinking lavishly and making a mess, lewd entertainment begins, and Sora is treated like a companion. Her large breasts, hidden beneath her kimono, are groped, her nipples are licked, and dirty hands reach for her crotch. Frustration from her busy daily life, and reason dulled by alcohol… she finally gives in and accepts the lustful penises of the older men. "I'm sorry, darling…" The beautiful wife who was cheated on goes out every night to entertain them with unprotected sex.
