四つん這い

A front-facing, eye-level anime illustration of a young woman in her underwear on all fours. She has shoulder-length, curly bob hair with bangs framing her face. Her expression is neutral with slightly parted lips and direct eye contact with the viewer. She wears a simple black bra and matching panties. Her hands are positioned on the ground with fingers splayed, knees tucked beneath her, creating a gentle arch in her back. Her breasts are visible through the bra. The background is plain white. The style features clean linework, smooth shading, and high-quality rendering with attention to fabric textures and skin highlights.
