Starring Ebisaki Ao, this work features Fitch's exclusive beauty with a slim waist and large breasts in a passionate role as a doctor! The theme focuses on oral sex treatment that pursues pleasure beyond SEX, utilizing various techniques like Glory Hole, PtoM, vacuum blowjob, deep throat, and screw oral sex to guide the resolution of male genital issues in the storyline.

The eroticism of the blowjob faces is outstanding, especially with Ao-chan's subjective scenes offering high immersion that captivates viewers. From the previous series, the stockings have been made thicker, creating a more sensual atmosphere, but in the initial chapter, the male actor's lack of reaction to the sudden leg-opening scene is a bit distracting, slightly diminishing the erotic appeal. Additionally, in the between-the-legs blowjob scene, masturbation starts and hands obstruct the view of the panties, which is a pity.

True to the title, there is less interaction, but it specializes in Ao-chan's oral skills, with her clever tongue use and tasting-like licking deserving the title 'Ultimate Blowjob.' The setting reminiscent of urology is realistic, and viewers with actual hospital visit experiences might find themselves so engrossed that they wish to meet a slutty doctor like Ao-chan.

However, the duration of each oral session is a bit long, leading to some feelings of redundancy, and it could have been better with more pacing. Overall, the quality is worthy of being called a masterpiece, full of charm that encourages completing the series. Ebisaki Ao's slutty performance and the eroticism of the blowjob shine throughout the film!
