(A compelling and intimate narrative scene), a young, tender-looking type-B schoolgirl is engaged in a private self-portrait session. She lies on her back on plain sheets, knees bent and parted naturally, forming the base of the composition. The pose is not exhibitionistic but one of unconscious relaxation born of deep focus. Soft window light from the side clearly illuminates her form and the full-length mirror positioned before her.

(Character state and intricate details), the girl’s face shows a complex mix of childish concentration, slight discomfort, and intense observation. Her gaze shifts between the mirror and her drawing board. Her body exhibits the described state: her vulva is noticeably reddened, swollen, engorged, presenting a plump, fleshy, and vividly pink hue that seems to glow with inner warmth. The critical detail: from the parted, tender petals, thick, creamy white, viscous fluid slowly seeps out, showing a stringy, glossy texture under the raking light. With one small, delicate hand (her slender fingers possibly smudged with pigment), she gently holds the sensitive, glistening area open for better visual access in the mirror.
