A dark, lightless ruin hidden underground... this is "Chijo Prison," ruled by the overwhelming power of G-cup breasts. No matter how desperately you beg for mercy, your pleas will be ignored. You'll be made to cum repeatedly, drained of every drop of semen until you're completely exhausted. The sight of her huge bouncing breasts swaying as she rides you in cowgirl position is a must-see. Despite appearances, this place harbors 10,000 times more danger than you can imagine.
