Sister and brother in uniform, desire undone.
A brother and sister, dressed in their pristine school uniforms, are confined to their room as punishment. The sister, her uniform buttoned up to her neck, feels the heat rising in her body. She watches her brother, his uniform sleeves rolled up, revealing tanned, muscular arms. He catches her looking and smirks, leaning back in his chair, his uniform pants tightening around his growing erection. She licks her lips, her eyes lingering on the bulge. He stands up, walking towards her, his uniform creaking. He unbuttons her blouse, his hands brushing against her skin, making her shiver. She reaches out, her fingers tracing the outline of his cock through his uniform. He growls, pushing her against the wall, their uniforms rubbing against each other, the sound of fabric against fabric filling the room as they lose themselves in their forbidden desire.
