The magically modified balance ball with a dildo is back, more powerful than ever! The third installment features a race between six sports-oriented female college students! With each bounce, the extra-thick dildo penetrates deep into the ball, slamming into the G-spot, making the girls scream, convulse, urinate, and squirt in a half-crying state of chaos! The more intense the bounce, the more their breasts pop out of their short T-shirts. A heart-pounding moment that heats up everyone's crotches! A big athletic meet full of girls is about to begin.
