"Why is a man like this my husband's coworker...?" Mao has always felt deeply uncomfortable around her husband's colleague, Ueda. Back when he was in sales, he was a sleazy man who would pressure her into dates just to secure contracts, leering at her body without shame. His attitude hasn't changed at all—he once again rudely ignores her husband and treats him with blatant disrespect right in front of her. Unable to stand it any longer, Mao finally confronts Ueda, unleashing all her pent-up frustration. Enraged, Ueda violently attacks her. Though she resists, Mao is overpowered and ruthlessly fucked, climaxing again and again under his brutal thrusting.
