Close-up on her face first. Red hair framing wide eyes and parted lips as the machine revs up — slow piston strokes teasing her bare pussy. Thighs splayed over the padded bench, green lube bottle nearby. Pace quickens. Dildo plunges relentless, hips bucking involuntarily. She grimaces, mouth agape — gasping through the rhythm. Legs tense. Machine hammers faster, her slim frame shaking violently against the metal frame. Juices drip. One final surge and she arches, quivering — spent but still strapped in.
