A married woman walks through the city on Friday nights because she always ends up alone after returning home. She readily accepts any invitations that come her way, even if they are last-minute. With excuses like, "Well, my husband is out drinking with his friends... just this once..." she finds herself giving in to temptation. As long as there's an alibi - like being drunk or working on an AV shoot - she doesn't consider it cheating. This horny Friday wife can't resist the opportunity for some fun under the guise of work.

金曜の夜に街を歩く人妻は、家に帰っても1人ぼっちだから、急な誘いも即OK。「どうせ旦那は飲み会だし…ちょっとだけなら…。」と、誘われるままにお酒を飲み、旦那のせい…酔ったせいにしながら、「一度だけなら不倫じゃない…AVの撮影なら仕事で浮気じゃない…。」言い訳さえあれば即ハメOK。ざわつく金曜マ〇コ。
