Everyone In My Company Falls Out After A Party, And The Only Ones Left Awake Are Me And My Colleague I Have A Crush On... - Yuuka Oshima - Yuka Oshima

Oshima Yuka is a colleague who finds herself alone with her superior, the President, after a company party. As they spend more time together, it becomes clear that he is a married man whose wife is cold and distant to him. He takes advantage of his situation and engages in a cheating encounter with Oshima Yuka, performing various sexual acts including blowjob and intercourse. This is a classic case of a cheating husband taking advantage of a vulnerable situation, which falls under the category of cheating wife/NTR content.
