In a dimly lit, industrial space, a circle of young, lean men stand, hands behind their backs, eyes downcast. Their master, a tall, muscular figure, paces around them, his gaze hungry. "Today, boys," he growls, "we explore the depths of your bodies." He stops before the first boy, his hand reaching out, fingers curling into a thick, meaty fist. The boy's breath hitches as the master presses against his hole, pushing in slowly, stretching the tight ring. The boy moans, his body tensing, then relaxing as the master's fist disappears, his arm disappearing up to the wrist. The master grins, his other hand reaching down to stroke the boy's hard cock, "Good boy," he murmurs, "you're taking it so well."
