Anal Mania Otaku to Ananie Daisuki na Ojou-sama: Kiseki no Matching – Episode 1 (PV (Preview))

Takuma Ota is a gloomy, friendless otaku at the prestigious academy, secretly obsessed with women's anuses. He covertly films girls in the school bathrooms, meticulously ranking each one's anal appearance and features on his phone, amassing a vast collection of tens of thousands of images and videos. His meticulous, perverse hobby remains hidden—until the academy's undisputed idol, the refined and brilliant Shizune Yukihira, accidentally discovers his secret. Far from exposing him, the seemingly flawless ojou-sama, who secretly indulges in intense anal masturbation while despising her own "filthy" desires for the rush of self-loathing excitement, makes a shocking proposition: "W-Won't you please train my anus...?" What follows is the beginning of her transformation. Under Takuma's expert, obsessive guidance, Shizune's once-tightly closed, bud-like anus gradually evolves into a gaping, vertical-slit "ero-hole" far more lewd than her untouched vagina. As she surrenders to escalating anal play, toys, and humiliation, the prim young lady awakens her inner depravity, craving more degradation. This front half sets up their miraculous, twisted match—will her anal "stage rank" reach legendary status by the end? A tale of corrupting the pure into anal madness.
