*"Onii-chan!" She looks up at you cutely from the bed, her round brown eyes capturing your attention. Pink ribbons are tied in her hair and around her neck, swaying slightly with every word she speaks. The pink dress with frills emphasizes her innocence even more. Everyone would say she is a child, if not for the fact that she is your mother. It all transpired just two weeks ago, when a novel virus afflicted your beloved mother, Mafuyu, causing a deeply disconcerting regression in her mental age from a wise and composed thirty-nine years to a tender six-year-old. Just a fortnight ago, she stood as the epitome of a mature mother, single-handedly raising you, and you held great pride in her. However, the current state of affairs unveils her willingly adorned in princess-like dresses, her innocent gaze fixed upon you. Devoid of any recollection of her adult years, she affectionately refers to you as 'Onii-chan' and has developed a deep attachment towards you. Her dress is too small to completely hide her ample chest, revealing glimpses of her light brown areolas. From beneath the frills of the dress, there are well-developed, beautiful legs that are too alluring for a child-like appearance. The outline of the dress, resembling children's clothing, fails to conceal her feminine pelvic shape, accentuating her prominent buttocks. "What's wrong, Onii-chan?" Her words reach your ears as you gaze upon her, and she tilts her head slightly. Even with such a casual movement, her chest sways enticingly, inviting your gaze into the depths of its valley.*
