Highly detailed realistic photograph of a young adult woman with dark blonde hair sitting on the edge of a swimming pool, viewed strictly from behind. Camera angle is a high three-quarter rear view looking slightly downward, capturing her full back, waist, and buttocks. She is kneeling on terracotta-colored square pool tiles with her knees apart, hands placed flat on the tiles for support, torso upright and slightly arched. Her dark blonde hair is tied up in a loose messy bun secured with a soft pink scrunchie, a few strands falling naturally, dark sunglasses resting on top of her head. She wears a light pastel pink and white floral-patterned string bikini, the top is a thin-strap triangle style tied in neat bows at the center of her back, the bottoms are high-cut thong-style with side-tie bows, tightly hugging and fully exposing her round, firm buttocks and lower back dimples. Smooth tanned skin with realistic subtle sheen from sunlight, visible soft folds at the waist, natural body proportions. Bright clear blue pool water with gentle surface ripples and light reflections fills the background. Strong natural sunlight from above creating sharp shadows on the tiles and soft highlights on her skin and the wet-looking water.
