Bored and curious, a brother and sister, both amateurs in the art of pleasure, find themselves alone and horny. They start by masturbating separately, she with her fingers and toys, he with his throbbing cock. Caught in the act, they argue, but the tension only heightens their desire. Soon, they're exploring each other's bodies, her tight pussy taking his thick cock, their amateur touches igniting a passion that's raw and uninhibited.
