"In this sweat-soaked yoga class, the instructor's thong becomes an unwilling participant in the workout. As she bends, stretches, and contorts her lithe body, her thong rides up, creating a lewd wedgie that leaves little to the imagination. The class is treated to a sloppy, up-close view of her ass, the thong strings digging into her flesh, as she valiantly attempts to maintain her instructional flow, her voice trembling with a mix of embarrassment and arousal."
