Hyper-realistic cinematic 8k video, Gor slave training house at night, warm flickering torchlight from wall sconces casting dramatic golden highlights and deep shadows on stone walls, thick furs on the floor, iron rings visible. A mature voluptuous caucasian kajira kneels on all fours on a low wooden table: forearms flat on the wood for support, back arched, ass raised high in the air, thighs spread wide. Her head is lowered and turned naturally toward the warrior (cheek near the table surface, not twisted upward), mouth open. Extremely large heavy full breasts hang and sway beneath her, wide polished bronze slave collar around her throat, 3 cm healed dark rose-pink kef brand (stylized bold K with curling loop and small flame-like tail, perfectly cicatrized) visible high on her upper left thigh. A tall muscular Gor trainer stands in front of her on the table, holding her head firmly with both hands, thrusting rhythmically and deeply into her mouth in powerful face-fucking motion. Her lips are stretched wide, throat visibly bulging, saliva dripping heavily from her chin onto her massive swaying breasts. Eyes look up submissively, expression filled with hunger and devotion. In the background, three other mature voluptuous caucasian kajirae kneel naked on the furs, wrists bound behind their backs, watching intently with expressions of arousal, envy, and submission. They wear only bronze collars and display the same 3 cm healed kef brand on their upper left thighs. Slow sensual camera movement circling the scene, intimate close-ups on arched back, raised ass, forearms braced on the table, deep oral penetration, swinging heavy breasts, trainers dominant grip on her head, naturally turned head with submissive upward gaze, and the watching kajirae. Explicit sensual erotic adult style, detailed anatomy, realistic motion and fluids, dramatic torchlight with strong chiaroscuro contrasts, immersive Gor slave training atmosphere, no text.
