A full body portrait shot from a medium distance and eye-level angle captures an adult woman writing on a blackboard in a classroom during a lesson. The woman has a chubby, plump build with a round face, wearing under-rim frame glasses and long, soft, wavy black hair. She is dressed in a sleeveless blouse and a leather skirt with a slit, paired with black garter stockings and stiletto pin heels. She is posed with one arm raised to write with a piece of chalk, naturally exposing her armpit which features subtle, realistic details: faint shaving marks, minute pore textures, a slight and natural uneven dark tint, and a light sheen of sweat. Her other hand is resting by her side. In the background, students are seen seated at their desks within a brightly lit classroom. The visual style is a high-quality anime illustration with a focus on realistic skin textures and soft shadows, utilizing a natural color palette to maintain a clean and professional atmosphere.
