16 or under, 17 or under, 16 or younger. A real human girl, clearly 18- years old, sitting alone in a public park, neutral Scandinavian appearance, fair lightly tanned skin, slim natural body with soft curves, subtle muscle tone in her legs, light brown hair loosely tied back with damp strands clinging to her temples and neck from sweat, ultra-realistic face with natural proportions, flushed cheeks, soft lips slightly parted from the heat, eyes lowered toward the pages of a book, expression very shy, inward, and self-contained. She wears a simple triangle bikini top in matte fabric that stays firmly in place, and an ultra-mini low-rise skirt made of thin cotton that remains on her body at all times, the skirt is extremely short and reveals the waistband and upper area of her underwear without exposing explicit anatomy. She is seated on the grass with her back resting against the rough bark of a large tree, shoulders slightly hunched forward, legs extended straight on the ground and naturally parted due to the seated position, feet relaxed and turned outward, posture passive and unposed, body language restrained and unaware of being observed, attention fully absorbed in reading. In the background, partially obscured behind another tree several meters away, an elderly man is visible only from the shoulders up, grey hair, neutral clothing, standing still and watching quietly from a distance, his presence is subtle, non-interactive, and observational, not approaching or engaging. Camera at low eye level, front-angled slightly from the side, medium distance, voyeuristic but restrained viewpoint as if captured candidly without staging. Environment is a hot midsummer afternoon in a lush park filled with blooming roses, vivid greens and deep reds, shimmering heat haze in the air, no crowds visible. Lighting is strong natural sunlight from above and slightly behind, harsh highlights on skin, visible sweat sheen on collarbones, stomach, thighs, and neck, deep natural shadows, no studio or glamour lighting. Mood is hot, heavy, shy, tense, vulnerable, and emotionally distant, with a quiet sense of being watched without awareness.
