A group of naughty kids go to a training camp with six busty moms from the moms' volleyball club. They can't contain their excitement at the sight of the moms' plump bodies. They sneak into the shower room and offer to wash their bodies, rubbing their breasts and trying to touch their private parts. In the training room, they have fun playing with the moms' big breasts and big butts as they sweat on the training machines.
