Upper-body close-up portrait emphasizing composition. A beautiful Japanese woman in her early 20s, with wet dark brown long hair swept back, strands naturally falling over her face, facing the camera with large eyes gazing directly, an alluring expression with lips lightly pursed. Gigantic breasts. The black bikini top features thin straps around the shoulders and neck, with chest cups made of fine mesh dot texture fabric that accentuates the ample bust and realistically depicts cleavage, with a gathered hem at the bottom. Perfectly reproduced proportions: slim waist, glamorous bust and body lines, smooth and glossy skin, wet texture. Background is a coastline, beautifully illuminating the skin.
