Prompt

Futanari granny, a chubby SSBBW, stands still in a quiet corner of the library between the tall shelves: her soft, heavy body in a loose sweater and long skirt, one hand resting on the heavy outline of her cock through the fabric while she pretends to read, the thick shape clearly visible only to anyone who happens to glance her way, a faint wet spot already forming as her breath stays carefully steady.
