Rio is a career woman fed up with her toxic boss and incompetent subordinates. After realizing the world is full of scumbags, she awakens a mysterious power within her massive chest. Now, she's hunting down creeps and draining them dry with her legendary, voluptuous body in this ultimate vigilante fantasy.




















Judging by the title, I thought it was just a drama, but... it was anything but. It was packed with highlights. Rio Hamasaki plays a heroine fighting evil, armed with top-tier breasts and sexual technique. She starts as a plain, bespectacled office worker who awakens into a masked, sadistic heroine, melting bad guys and finishing them off. It's a bit funny that she has 'Sexual Technique' written in red on her right arm and 'Justice' in black on her left, but... Still, Rio's body is absolutely captivating. Despite her slender, delicate frame, she has that perfect 'bon-kyu-bon' golden ratio body. Even with such size, it's firm, beautifully shaped, and yet so soft and bouncy! Rio isn't just about big breasts; her beautiful, shapely butt looks amazing from every angle. I especially love the cowgirl and doggy style scenes. The male actors are rock-hard throughout the H-scenes (lol). Well, you can't blame them when they're with Rio... She's a good actress, but when she enters 'H-mode,' her sexiness is off the charts. Her provocative lines and dirty talk are just too hot! Her fellatio is incredibly skilled and looks so pleasurable, and the tit-fucks are irresistible. I used to wonder if tit-fucks were actually good, but watching Rio, there's no doubt it feels amazing. She's so incredibly erotic, but there's a story that she worked at a gas station before her debut, and a scout chased her for six months before she finally agreed. Seeing her now, it's hard to believe she resisted for half a year—she's just too naturally sexy! I guess she always had the talent for it.
I'm absolutely smitten with Rio Hamasaki's body. The lesbian scene with the dominatrix is the absolute highlight. I couldn't care less about the skits, though.
*The original manga from the 1970s had the most innovative design of the main character, but the story was an uninteresting work. Of course, this isn't a big deal in terms of the story either, and I wanted it to be made to a point where it wouldn't bother me. However, it is a miracle that a real person is far more complete than the woman depicted in the original painting. Cheap sets, dialogue, and screen production are no longer a big problem. Ugly cute office lady with glasses, good. In the final encounter, she is a plain-looking woman, and it's nice to have sex with light makeup. A tight-fitting blouse worn at work is a classic way to show off big breasts. The design of the breast mask is also highly complete. It accentuates Hamasaki's torso line, draws attention naturally to it, and gives her body a fresh new look. The movie-style title background at the end shows her walking in the style of ``an old ugly office lady looking a little stylish,'' and even there, she brings out an unprecedented charm. This work as a whole is full of love for actress Rio Hamasaki and an attitude of trying to bring out her best qualities. I wonder if they could have added one more setting: ``You can't transform unless your breasts are thoroughly massaged.'' For example, he molests people on the train, asks a new employee who admires him to rub him, and sometimes he uses the desires of his enemies to successfully transform himself. The enemy dies because the energy is absorbed by the breast mask through sex, but the breast mask shares that energy with good people through sex, and those who receive it are blessed with good fortune... I think they could have made several one-hour story AVs like this. Looking at the end title, it seems like they were thinking about the possibility of a sequel...but it's a waste to end it with just one! <Rio Hamasaki's works are of a high level, so I'm lowering the value of ☆. Actual ☆6 or more>
Rio Hamasaki plays a gloomy department head. She's looked down upon by her subordinates, but who knew she was actually the 'Boob Mask'...? As expected of the 'Boob Mask,' she has amazing breasts. They are top-tier. I think there were a lot of unnecessary scenes, but it was a work where you could fully enjoy such wonderful breasts.
It doesn't overemphasize the drama and surprisingly stays true to being an AV. You don't really feel the influence of the source material; it's more of a parody AV. I like that it's not just about nympho-style sex scenes; for instance, even during the 'punishment' scenes for the men, the woman is the one being made to feel it more. My personal recommendation is the lesbian punishment scene where a sadistic queen is broken down into a masochist. Seeing her stern face melt into a submissive expression is incredibly erotic.
