Nana Maeno announced her retirement from the AV industry in March 2025, revealing her intention to retire a year prior—in March of this year. As part of a countdown project leading to her departure, she was asked about her desired final works to shoot. Among several titles, she specifically mentioned the drama "Classmates" co-starring Aya Shiomi (affectionately known as Shiomin). Another surprising project she revealed was "Lesbian Fist Unlocked." This shocked many fans, as she had previously declared she would never shoot anal or fist scenes before retiring.
Nana began studying classical ballet as a child, striving to become a professional ballerina. However, failing to go pro in her late teens, she found her path blocked and eventually entered the AV industry after years of uncertainty. Originally far removed from eroticism, she leveraged her ballet-trained flexibility to enter BDSM-themed works, gradually gaining popularity.
Meanwhile, Shiomin (Aya Shiomi) has a deep fascination with BDSM, embodying an abnormal persona who transforms pain and suffering into pleasure. The two first met through an SM night event. Initially overwhelmed by their differences, Nana became inspired after witnessing Shiomin's intense performance, gradually developing a desire to experience more extreme SM herself.
This release, "Restrained Lesbian Fist," marks a bold departure from previous lesbian fist-fucking works. Nana, known for her normal demeanor, experiences fist insertion for the first time. Her tears—born from both pain and pleasure—are raw and unforgettable. Shiomin sadistically dominates her, culminating in a scene where they each insert fists into one another's genitals. Their bond deepens until, in the end, they sob while mutually fist-fucking each other.
This film fully documents a normal girl's journey into the abnormal world of fisting. Her expressions of pain, her sweat-soaked body—unexpectedly erotic—will move many viewers. Before her retirement, experience Nana Maeno's emotional reason for finally unlocking fisting.
