In a dungeon of shadows and moans, a submissive is restrained on a fuck machine, their breasts bound and hair pulled taut by cruel leather straps. The machine's arm swings back and forth, driving a thick cock into the sub's hungry cunt, while a buzzing vibrator punishes their clit. The sub's cries are muffled by a ball gag, their eyes watering as they struggle to hold back their orgasm, their body coated in a sheen of oil and sweat.
