I watched this work starring Yabe Hisae, and the immoral story themed around her son's debt repayment first drew me in. The sight of her, beautiful and full of charm, being trained by ruthless loan sharks is truly a series of shocks. Particularly, the fisting play is so intense it makes you want to look away; in the initial insertion scene, there was an accident where she grimaced in pain, but the male actor ignoring it and continuing added a realism that's irresistible. Her pained voice and pale expression, completely different from usual sex, instead heightened the excitement, and in the several deep fistings, her convulsions and moans upon climax exuded an unprecedented eroticism. The interactions with her son also carried a sense of immorality, with realistic acting shining through. I originally had no interest in fisting works, but this one captivated me at once with its realistic depiction, keeping me glued until the end. The process of the beautiful mother transforming into a perverted woman is a parade of extreme play that shatters reason, a must-see for fans.
