1st Prize for Cock Eruption

It is the school science fair. Mariah is going up against Pete for the first prize. The judge is conflicted, going back and forth between the two booths, so Mariah knows she has to keep stepping up her presentation, and what she lacks in science, she makes up for in sex. After Pete's volcano eruption Mariah demonstrates how the female body can cause a much bigger eruption: the judge's cock.
