Attackers 20th Anniversary I want to be loved by you. Special Edition Amami Tsubasa

This movie features a cheating wife, Uchida's wife, who is in a difficult circumstance where her husband's job is at risk. She is approached by her president, Saeki, who offers to save her husband's job in exchange for sexual favors, leading to a creampie and possibly other explicit acts. The central kink of this movie appears to be the exploitation of the wife's desperation and the power dynamic between her and the president.
