Prompt

A lithe adult woman with towering breasts, a curvaceous butt and a slender frame arches her back on a dark bedroom floor, her sweat-slicked skin glistening as a colossal three-leg-wide cock thrusts deep into her over-stretched, gaping vagina, the massive shaft filling and stretching her inner walls far beyond ordinary limits while her tits bounce fiercely with each powerful thrust. Her mouth hangs open in a guttural gasp, eyes half-closed in raw, intense pleasure, as the hyper-realistic scene captures every ripple of flesh, the tight vaginal walls contracting around the enormous penis with vivid detail. Soft rim lighting from a low studio spot casts a glossy sheen over her body, creating dramatic, low-key shadows and a shallow depth of field that isolates the invasive act in razor-sharp focus while the background fades into velvety darkness. Shot from a low angle looking up at her face and thighs, the composition emphasizes the staggering scale contrast between the massive cock and her delicate limbs, rendered in ultra-detailed 8K cinematic photography style.
