Nana Maeno chose "Female Prisoner Torture" for her final shoot with TOHJIRO within the video production period lasting until December 2024. The staff were surprised she specifically requested this particularly painful BDSM performance. Kinbaku master Akira Naka returned to tie her up, marking their first collaboration in 12 years as a golden duo on the "Female Prisoner Torture" series. For the ending scene, they planned to film her hanging stones from her genitals at Suruga Bay. The shoot included a scene with heavy snow falling in front of a latticed door, where Nana posed with stones dangling from her genitals—this single pose, shot first thing in the morning, reportedly exhausted her physically. Next came package photography, featuring Nana's first-ever "triangle horse punishment." Dressed in a female prisoner outfit, she looked perfectly suited for the role. After a lunch break, they moved straight into intense scenes: "female prisoner room, tight bondage, spread-leg torture with rope" followed by "triangle horse punishment." Nana's crying performance was as outstanding as always, powerfully drawing viewers into the scene. However, the triangle horse caused significant pubic pain, evident in her pained expressions. Next came the long-awaited "stone-holding torture," something Nana had always wanted to try. Using stones previously crafted by Akira, each weighing over 10kg, she was forced to embrace four of them—an excruciatingly painful ordeal. Her stone-holding and soy sauce torture scenes were extremely intense, leaving her shins trembling violently like French bread, making it nearly impossible for her to stand. Finally, she endured massive water torture while suspended upside down, bringing her SM journey to a close. Four years ago, during her first SM night event, she watched a senior perform "stone-holding torture" and silently vowed to experience it herself one day. Nana, thank you for your incredible dedication and hard work throughout the past four years as part of the female masochist unit.
