Maeno Nana will retire from AV in March 2025. Nana announced her retirement exactly one year ago this March. When asked what she wanted to shoot during the countdown, she mentioned several projects she wanted to try. One of them was to co-star in a drama with Shiomin (Ayano Shiomi)!! That's when she shot "Classmate" (to be released in August 2024). And there was another project she wanted to co-star in with Shiomin!! "Lesbian fisting now allowed"!! Honestly, I was quite surprised by this!! Because I thought that Nana would never do anal or fisting until she retired!! I'm not the only one who thinks this way, I'm sure all Nana fans feel the same way!! Originally, Nana-chan had been learning classical ballet since she was a child, and was a girl who had been serious about ballet and had been aiming to become a professional ballerina. In her late teens, she gave up on her dream of becoming a professional ballerina, and she was at a loss and lost track of where to go!! I don't know what she got up to, but a few years later she entered the adult industry. This young lady had always lived a life far from erotic! I met her because I invited her into the world of SM, as her body happened to be very flexible, having been trained through ballet. Three years have passed since then. In 2021, Ayano Shiomi joined the M-girls group at the same time and started performing at SM nights. Aya is the complete opposite of Nana, a perverted woman who lives for SM and cannot live without it, an abnormal woman for whom pain and suffering lead to pleasure. To Nana, who is completely sexually normal, Aya's existence must have seemed unbelievably crazy at first. In the SM night performance, Aya is whipped with a single whip, covered in wounds, and goes crazy. I think that Nana, who watched that all the time, ignited the competitive Kokoro of an athlete!! I want to be able to do more intense SM too!! Over the next three years, the Kokoro between the two of them and their bond grew stronger than I ever imagined. I think this "Bound Lesbian Fist" is a work with a completely different feel from the 40 or so lesbian fisting works I've shot up until now!! Nana-chan is not a pervert or a dirty pervert, but just a normal girl, and she takes on the ultimate abnormal lesbian fisting challenge! This is the first video I've seen of her crying in pain when her fist goes in for the first time! Aya says, "You're going to cry a lot," and Nana says, "I'm not crying because I don't like it. I'm crying because I'm happy. But it hurts." While they're having this conversation, Nana's pussy is taking in the fist! Aya continues to sadistically torture Nana, who is in pain. I have never seen such realistic fist training in a video before. In the final section, Nana gradually begins to understand and feel the pleasure of fisting. When the two of them insert their fists into each other's genitals, Aya also begins to cry. It is the moment when their Kokoro are completely connected!! The two of them are crying after fisting each other!! This lesbian fisting wouldn't have been possible without the absolute trust between the two of them! Why did Nana decide to start fisting before her retirement? That feeling!! I want everyone to see it!! This work is a complete documentary of a normal, not lewd, girl being trained in fisting!! The way he was in pain and the sight of him sweating profusely was strangely erotic.
