(masterpiece, best quality, ultra-detailed, photorealistic, RAW photo), a stunningly beautiful young woman in her early 20s with a perfect, fit, and voluptuous hourglass figure and flawless sun-kissed olive skin.

Her left hand is raised, running through her wet hair. Her back is perfectly arched, pushing out her incredible ass. She is wearing an extremely skimpy and revealing two-piece string bikini. The top is a neon lime green micro triangle top with thin strings, barely containing her breasts and revealing ample sideboob. The bottom is a tiny, low-rise, emerald green g-string thong that is pulled up high on her hips and wedged deep into her ass crack, fully exposing her perfectly round, firm, and plump butt cheeks.

The setting is a bright, sunny day on a lush green lawn, with a blurred background of trees creating a beautiful bokeh effect.

The focus is sharp on her, capturing every detail of her expression, the water spray, and her exposed ass., (shallow depth of field, vibrant colors, erotic, playful), .
