Nagisa, who comes from being spoiled, goes "thud" with compression & demon piston, and arches her back like a shrimp, short-circuiting. Her reason is also broken, her uterus is in a frenzy, and her pleasure server is down. An abnormal development document that updates "I can't take it anymore!" to an unstoppable bug convulsive climax.
