Low candlelight flickers over her bound wrists in “僕にしか触れないサキュバス三姉妹に搾られる 4”. Silk ties keep her spread on the bed, blindfold heightening every touch. She writhes as a feather, then fingers, then a buzzing toy teases her. “僕にしか触れないサキュバス三姉妹に搾られる 4” records every helpless moan, every plea. When the vibrator finally presses against her clit while fingers curl inside, her orgasm is explosive—body straining against ropes, muffled screams of pure surrender.
