In a swaying bath, her heart and body are those of a married woman. Together they embark on a journey filled with hot springs—the wife suspects that her husband, whose interest in her has waned, may be cheating on her. She enjoys teasing him with playful banter while kissing him passionately, her sensitive body responding eagerly to his touches. When he strokes his hardness with just his mouth, she readily accepts penetration and rides him, searching for pleasure by changing the rhythm of her hips. After dinner and a game of ping pong, they make love again; the wife moans in ecstasy when he hits her G-spot deep inside. The following morning, she squirms and gasps for air as she nearly climaxes during their steamy shower together.

湯に揺れ、恋に揺れる、人妻のココロとカラダ。丸ごと一緒に温泉の旅へ──。自分への興味が減りつつある夫の浮気を疑う人妻が旅へ。会話遊びを好む人妻は軽口を叩きながらキス、身体を弄られると敏感な反応をみせのけ反り悶絶。肉棒を口だけでしごき固くすると挿入を受け入れ、騎乗位では気持ちいい所を探るように腰の動きを変えて湿った音を響かせる。浴衣を綺麗に着こなし夕食と卓球を楽しみ、再びSEX。奥が好きな人妻は突かれて「奥！奥！」と身悶える。翌朝は露天風呂でのぼせる寸前まで尻を振って喘ぎまくる。
