June Alderidge leads her sisterhood of sirens in a nocturnal swim, their bodies silhouetted against the lunar reflection on the water's surface. As they congregate in the lake's deepest point, the women form a circle, their breath visible in the cool air. June, her nipples hard from the chill, begins to masturbate, her moans low and sultry. The other women follow suit, their hands sliding between their thighs, their eyes locked on June's writhing form. Their orgasms ripple through the water, their cries of release echoing the calls of the nocturnal creatures around them.
