'Ultimate Pink Nipple' is a film showcasing the charming performance of Ishikawa Mio. Her cuteness and eroticism are still captivating, especially her enchanting paizuri skills in the final sex scene. However, the storyline is a bit monotonous and lacks excitement. It may not fully satisfy those who enjoy facials. Nevertheless, it is commendable for its portrayal of the beauty of Ishikawa Mio's breasts and smooth body. Her nipple orgasms and paizuri scenes are a must-see.
