In a luxurious boudoir, a dominant woman oversees her sub's transformation. She selects a pair of silky panties, her voice firm as she instructs him to slip them on. He complies, the cool fabric against his skin awakening new sensations. She guides his hands to his crotch, commanding him to stroke his growing erection through the panties. His bisexual curiosity piqued, he eagerly pleases himself, the sight of his hard cock straining against the feminine underwear fueling his mistress's desires.
