Medieval European iron torture devices make an appearance. Cold metal bites harshly into the woman's body, subjecting her to intense restraints that defy human anatomy. In this production, Kuroki Ikumi becomes the target of this torture, as her helpless anus is relentlessly assaulted by cocks, toys, and even legendary torture implements. Under the painful domination, her body gradually transforms from agony to pleasure. A shocking work that fully captures this transformation.
