Dark basement, photorealistic 4K video, a 28-year-old very slim woman with extremely pale white skin and long straight blonde hair, completely naked, lying face-down on a dirty mattress. Small scratches and red marks on her back and thighs. Her mouth is tightly sealed with wide black duct tape, muffled desperate sobbing and crying, tears pouring down her face. Wrists handcuffed behind her back with steel cuffs, ankles spread wide and locked in heavy metal shackles chained to the floor, chains rattling weakly as she tries to struggle. A huge muscular black man wearing a terrifying full-face black skull mask is lying completely on top of her in prone-bone position, brutally pounding his extremely long and thick erect penis deep into her tight anus, savage rough anal sex, her pale slim body violently jolting with every merciless thrust, sweat and tears everywhere, dim red lighting from a single bulb, ultra-realistic pale skin, scratches, bruises and trembling, 4K, <lora:realisticSkin_v2:.7>, (extremely pale white skin:1.6), (long blonde hair:1.4), (very slim body:1.7), (black duct tape gag:1.7), (muffled crying:1.8), (scratches and bruises:1.5), (terrifying skull mask:1.6), (extremely huge thick penis:1.8), (rough prone-bone anal:1.9), (brutal deep thrusting:1.9), (handcuffed and shackled:1.7), (man lying fully on top:1.7), (28 years old:1.5), (adult woman:1.6)
