[Akuochisukii Sensei] White Rose - the Insanity of Extreme Alteration Experiment (Kikaikan de Monzetsu Iki Jigoku! Vol. 3) [Kuraudo]

White Rose, a proud magical girl who shreds Dr. Romanesco's monsters without breaking a sweat, finally gets captured and strapped into the mad scientist's custom-built pleasure machines. Her huge breasts are worked over by relentless sucking apparatus while her clit is stimulated into obscene growth, lactation and body modification wringing climax after climax from her body even as she screams that her heart will never surrender. With her memories of fighting beside her comrades starting to fade and the doctor vowing to unleash everything, the real battle becomes whether her will can outlast the mind-breaking escalation.
