An 18-year-old woman with long, straight black hair sexy posing in a gym locker room. She is wearing an extremely revealing, tight white crop top that barely covers her large, youthful breasts, exposing her toned abs and a significant amount of cleavage. The top is designed to enhance and emphasize her chest and slim figure. She is also wearing extremely short, tight black athletic shorts that are cut high on the hips, fully revealing her toned thighs and accentuating her perfectly shaped, firm, youthful buttocks. The shorts barely cover her lower body, leaving her curvy hips and firm glutes fully exposed, creating a highly seductive look. Her pose is slightly turned, with her hand resting seductively on her hip, drawing attention to her hourglass figure. She holds a phone in one hand while looking at herself in the mirror with a confident, playful expression. The lighting in the room is dim and moody, casting soft shadows that highlight the smooth curves of her body and the definition of her muscles. The background features wooden lockers and a modern gym atmosphere, which contrasts with her revealing, sexy outfit. Her face has full lips, well-defined cheekbones, and a straight nose, with perfectly shaped eyebrows. Her skin is smooth, and flawless, with no visible tattoos or imperfections, showing no signs of aging or blemishes. masterpiece, photorealistic, ultra-detailed, high resolution, HDR, ISO 100, low lighting, soft shadows, minimal noise, sharp focus, perfect composition, youthful, slim waist, toned abs, large breasts, curvy hips, firm buttocks, toned thighs, revealing outfit, smooth skin, no tattoos, (large breasts:1.3), (firm buttocks:1.3), (toned abs:1.2), (flawless skin:1.2), (youthful:1.3), full lips, straight nose, perfectly shaped eyebrows, playful expression, (confident pose:1.2), (natural smile:1.1), (playful expression:1.2), extremely revealing white crop top, extremely tight short black athletic shorts, large over-ear headphones, dim lighting, wooden lockers, gym environment, subtle highlights, (soft shadows:1.2), (detailed background:1.1), confident, seductive
