In the dimly lit room, the inked tutor stands, his massive cock already hard, as his young stepbrothers tentatively undress. The twins, their bodies smooth and unmarked, look to their mentor for guidance. He shows them the art of gay love, his hands guiding their heads as they take turns sucking his thick cock. Soon, the brothers are moaning, their own cocks hard, as they learn to pleasure each other, their taboo lust growing with each deep thrust and hungry swallow.
