Adult porn actress Kurumi Kogoromo and her natural J-cup tits take on a simple challenge: make the male performer cum within five minutes while riding him to win a cash prize. She licks his nipples, gives him a camera-facing vacuum blowjob, then mounts him as her huge tits bounce with every thrust. She shows the smooth pink connection in spread-leg and reverse cowgirl positions, but narrowly misses the time limit. For the penalty, he creampies her in cowgirl, then she sandwiches his cock between her massive breasts and cleans it with her mouth, draining every last drop.
