A bisexual slave is trained by his mistress in a session filled with bi-sexual fantasies come to life. She orders him to pleasure her with his tongue, his cock, and even his ass, switching between roles to keep him guessing. She makes him wear a strap-on, fucking him while he's dressed in lingerie, and then switching places, making him take her cock. The slave's humiliation is evident, but so is his growing arousal, his body responding to the taboo acts and the mistress's skilled touch.
