MIAB-504 A geeky brother builds a body controller and uses it on his dark-skinned gal sister. Rika Tsubaki

After years of isolation, a geeky older brother completes a female body controller that lets him control women freely. He uses it on his dark-skinned gal sister, making her do obscene movements against her will, including shaking her hips and starting a cowgirl position. He pounds her and cums inside her repeatedly, milking her with the impossible controls. Runtime is 119 minutes, released in 2025.
