Ultra realistic cinematic erotic horror scene in a dark, wet secret underground laboratory with broken glass and glowing green emergency lights. A beautiful 37-year-old new combat MILF operative: seductive mature face, long straight black hair with silver streaks, sharp alluring eyes, full glossy lips, elegant features. Extreme bimbo MILF body massive heavy breasts, narrow waist, very wide hips, thick thighs. She wears a torn tight dark blue elegant skirt suit, deep cleavage, short pencil skirt ripped up, black thigh-high stockings with runs, red high stilettos (one lost), tactical holsters and straps still attached. She is being violently overpowered by a huge smooth slimy eyeless monster. The creature has a perfectly smooth glossy white body, no eyes, no face only a large round spiked mouth full of sharp fleshy spikes. Instead of a tongue, it has a long, thick, pulsating pink-white worm-like tentacle coming out of its maw. The thick worm-tentacle is brutally forced deep into her mouth and throat, stretching her lips wide around the spiked maw. The worm is actively pumping and thrusting, injecting thick glowing white viscous liquid straight down her throat. Heavy amounts of white cum overflow from her stretched mouth, dripping down her chin, neck and soaking her huge breasts. Her neck visibly bulges from the thickness of the worm. Her expression is a mix of shock, resistance and forced pleasure eyes half-rolled, tears running. One hand weakly holds a dropped pistol, the other pushes against the smooth white body of the monster. Body arched, legs shaking, skirt completely lifted. Atmosphere: dark, wet, slimy, dangerous. Slick reflections on the monsters smooth white skin, dim lighting, erotic horror mood, photorealistic, 8k, masterpiece, extremely detailed, explicit, high quality.
