A stern dominatrix, clad in latex and wielding a thick strap-on, takes a bisexual submissive under her wing. 'Your dick sucking skills need work,' she sneers, guiding his head down to her harnessed cock. He eagerly learns, gagging and choking as she face-fucks him, his own erect cock betraying his arousal. She humiliates him further, mocking his bisexual confusion, before switching to her own wet pussy, making him lick her clean.
