Nijigen Comic Magazine: Futanari Kikaikan Seieki wo Shiboritsukusu Kikai Zeme Jigoku!!
二次元コミックマガジン ふたなり機械姦 精液を搾り尽くす機械責め地獄！！
A collection of eight erotic stories where futanari characters find themselves trapped in mechanical torment. In one tale, a phantom thief is caught by a security system designed to humiliate her. Another follows a female officer whose solo investigation leads to a compromising situation. A third story features a general subjected to a futanari modification experiment.
Across these narratives, heroines and ordinary women alike are captured and forced into machines that stimulate and drain them. Whether through scientific devices or supernatural encounters, each character endures relentless mechanical stimulation that pushes them to their limits. The stories explore themes of restraint, transformation, and loss of control.
