Mercury Soles saunters over to her unsuspecting classmate, a mischievous glint in her eye. She slides onto his lap, straddling him as she leans in close, her warm breath tickling his ear. 'I have a little secret,' she purrs, her voice low and sultry. 'I think you might just have a foot fetish.' She lifts one leg, draping it over his thigh, her bare foot hovering inches from his crotch. 'Let's put it to the test, shall we?' With a coy smile, she begins to slowly, deliberately rub her toes against his clothed erection, the sensation sending a jolt of pleasure through him. Mercury Soles watches his reaction intently, her foot never stopping its teasing motion as she gauges his response, waiting to see if her suspicions are correct.
