That JAV

Picking up a pair of good friends, 6 college girls enter a naughty game project for self-improvement and prize money! They play hula hoop, swing their hips, do pushups, and get their chests tipped and pussy smeared, then get their first fixed dildo insertion, which causes a massive squirt and continuous orgasm! Pile up/grind/spider, different girls have different ways of swinging their hips! Abnormal fluids come out from the upper and lower mouths! The dildo that stimulates the mouth of the uterus makes them cum over the K point and they can't stop cumming! Which college girl succeeded in the challenge?
