Seamless perfect loop. Woman slowly and painfully moves forward onto the cock, taking it deeper into her mouth, inch by inch, swallowing more length, struggling but determined, never breaking eye contact with camera, staring intensely throughout, eyes locked on viewer, until she reaches the base, hilt deep, nose against man, then cum dribbles and flows steadily from her mouth corners, continuous dripping, she holds at bottom briefly, then slowly pulls back up the shaft, releasing the depth, back to starting position with cock at her lips, then repeats the slow painful descent. Eye contact maintained entire time. Slow seductive rhythm, one complete cycle of taking it deep and pulling back.
