Bertha, a dominant woman with a penchant for punishment, transforms her spare room into a chamber of carnal chastisement. The room is dimly lit, adorned with whips, paddles, and other implements of pleasure-pain. She awaits her willing submissive, who enters, eyes downcast, ready to receive his penance. Bertha, clad in a form-fitting leather catsuit, orders him to strip, his naked body trembling with anticipation. She begins with a soft caress, then sudden, sharp smacks with a riding crop, leaving red welts on his pale flesh. He moans, his cock growing hard, betraying his arousal. Bertha smirks, her own juices soaking her panties, ready to deliver more.
