MIAB-504 I, who developed a female body controller, repeatedly made my black gyaru younger sister lose control and go wild. Tsubaki Rika

After years of staying shut in, an otaku older brother finally completes a female body controller that lets him manipulate a woman at will. He can control her curves and movements however he wants. By forcing her body to move against her will, he makes her act in suggestive ways. Even cleaning and intimate teasing can be started with the press of a button. Overwhelmed by the unnatural control and intense sensations, his black gyaru younger sister’s body begins to malfunction, and she is driven into a runaway frenzy and repeated climax.
