Highly detailed photorealistic erotic portrait of a beautiful adult woman in her early 20s taking a mirror selfie in a modern bathroom, viewed from a slightly low three-quarter angle. She has a sexy Chibi Moon inspired costume with heavy erotic modifications. Long wavy blonde hair styled in high pigtails with two large rounded odango buns on top of her head, strands cascading down her back and over her shoulders. She has striking blue eyes, full pouty lips slightly pursed in a seductive kissy face, and smooth tanned skin with realistic pores, subtle highlights, and natural soft shading. She wears a tight white crop top with a shiny pink sailor collar and a large glossy pink bow centered on her chest, the top is extremely short and pulled up high, fully exposing underboobs and the lower curves of her large, young, round, full breasts that spill heavily out from beneath the fabric, soft and gravity-affected with natural cleavage and detailed skin texture. A pink leather choker sits snugly around her neck. Her toned midriff is completely bare, showing defined abs and a flat stomach. She wears an extremely short shiny pink micro pleated miniskirt that barely covers her hips, riding high on her large, firm, round ass which is prominently pushed out and emphasized by her pose, the skirt so short that the lower curves of her buttocks are clearly visible. Long white opera gloves with pink striped cuffs reach past her elbows, one hand holds a silver iPhone up to take the selfie while the other rests near her hip. Shiny pink thigh-high boots with white trim and small bows hug her long toned legs. Her body is athletic yet voluptuous, with exaggerated but realistic proportions emphasizing large round breasts and a big firm round ass. Soft bathroom lighting reflects off the glossy costume materials and her skin. Background shows white tiled walls, a partial view of a sink counter, and tropical leaf-patterned wallpaper.
