In a room illuminated by twilight, a plus-size model, Megumin, lay sprawled on her bed. Her large, plump body was adorned with a small, form-fitting red dress that accentuated her small waist and massive tits. A witch's hat rested casually on her brunette hair, and thigh-highs peeked from under the hem of her dress. A mysterious staff leaned against the bedside, its tip pointing towards an unusual sight - Megumin's anus, which appeared black against her skin, was unusually prominent and gaping, with thick, puffy anal lips. Despite the oddity, a small smile graced her lips, as if she found it amusing.
