In a dimly lit room, a mistress begins her slave's bi-sexual awakening, dressing him in silky panties and stockings, his manhood tenting the fabric. She teases him relentlessly, running a crop along his body, making him dance and pose for her amusement. She brings in a muscular man, ordering her slave to kiss and caress him, watching as they grow harder. She takes control, using a strap-on to dominate them both, switching between their eager mouths and hard cocks, pushing their boundaries in this bisexual training session.
