This work depicting Mitsuyu Aizawa's experience at a muscle bar starts with her initial reluctance, but she gradually gets captivated by the pheromones and strength of the muscular men, excellently portraying the struggle between reason and instinct. Her soft and beautiful body being violently shaken by the intense play of the muscular actor is breathtaking, especially the scene where her toned waist and curvaceous buttocks beautifully writhe under fierce impact, which is intensely erotic. The camerawork is superb, with the powerful scenes of physical combat firmly imprinted on the eyes, and the moment she is effortlessly lifted by large arms and brought to climax with intense piston-like movements is so realistic in sound and motion that it's astounding. Mitsuyu's expressions are incredibly sexy, and the authentic transition from initial unwillingness to gradually succumbing to instinct is thrilling. The story isn't just NTR; it carefully depicts the conflict between reason and instinct, and her breathless plea of "Please do that again..." after climaxing from a bridge-position piston thrust targeting the cervix is super hot. The revenge purchase was worth it, dispelling any lingering frustration from previous works. Her character and voluminous physique make the dominance by the muscular men stand out, and the teasing during insertion scenes is effective. Her subtle expressions as a woman thinking with her womb and her convulsive, shrimp-arch trembling are the pinnacle of eroticism. The interaction with the serious manager played by Mr. Uchimura is convincing, and the all-out power sex enhances the work's backbone. Although questions about shochu protein mix remain, overall, it's a highly satisfying piece.
