Highly detailed, cinematic erotic scene in a dimly lit top secret underground laboratory filled with glowing monitors, bubbling test tubes, sparking electrical equipment, and steel examination tables. In the center, a voluptuous chubby thick woman with massive heavy tits and a huge round jiggling ass, long black hair cascading down her back, is bent over a lab table getting her tight wet vagina deeply penetrated by a massive thick penis. She wears heavy dramatic clown makeup, plus a sexy revealing black and purple clown outfit that's torn open at the crotch and chest — fishnet stockings, ruffled mini skirt pulled up, tight corset top barely containing her enormous breasts. Her expression is one of intense pleasure and ecstasy. She's being fucked hard from behind by a giant beast-like Frankenstein monster man, tall and muscular with patchwork scarred green-tinged skin, bolts in his neck, and exposed mechanical wires and cables hanging from his body and sparking with electricity. His body is monstrous and powerful, veins bulging. Dramatic volumetric lighting, purple and blue neon highlights, sweat and fluids glistening on their bodies, explicit penetration view, pussy juice dripping, dynamic motion, ultra-realistic textures, 8k photorealistic, sharp focus, best quality."
