Mistress Severa, clad in towering heels and shimmering pantyhose, takes center stage in her private domain. Her submissive, bound and gagged, kneels before her, eyes wide with anticipation. She runs a gloved hand over his crotch, feeling his arousal grow. With a cruel smile, she orders him to maintain his erection despite the pain she's about to inflict. She produces a CBT device, attaching it to his sensitive flesh. As she tightens the screws, he winces, but Mistress Severa only laughs, enjoying his discomfort as she continues her relentless torment.
