Petite teens Alicia Williams and Kira Perez, step-siblings with a secret, invite their friends to a yoga session that turns into a steamy foursome. As they stretch and bend, their lithe bodies glisten with sweat, hinting at the carnal desires hidden beneath their tight workout gear. Peter Green, their stepfather, joins in, catching the girls in a compromising pose. The tension mounts as they start to touch, their breath hitching with each illicit caress. Joined by Gunnar Stone, the teens give in to their taboo fantasies, forming a writhing, moaning mass of young flesh and pent-up lust.
