Masterpiece, best quality, 42yo adult female, jet black hair in a loose and disheveled low chignon, refined plastic surgery enhancements, high sculpted cheekbones, plump filler lips parted in a delirious moan, eyes rolled back in extreme pleasure, expression of a demented banshee reaching peak orgasm. Primary biological male 38yo, wearing thick-rimmed glasses, soft academic expression, lean but toned build, gripping her hips with loving tenderness. He is standing behind her, burying his massive thick veiny shaft deep inside her pussy with long slow deliberate strokes., (explicit stretching of the vaginal introitus with deep penetration:1.2), glistening wetness, soft skin contact compression. Her high-waist black heavy satin pencil skirt is pushed up to her waist, and her emerald green liquid-silk blouse is unbuttoned and sliding off one shoulder, the shimmering fabric clinging to her sweat-dampened skin. Gothic university office background, mahogany desk and leather-bound books, warm amber light from a green shaded banker's lamp. Rear-three quarter view, low angle showing the slow depth of the shaft and her arched back, 8k resolution, hyper-realistic, 35mm lens, professional photography.
