Bound and gagged in the asylum's dimly lit dungeon, a wild-eyed nympho squirms in anticipation of her unusual therapy. Her doctor, a stern, imposing figure, orders her to service his massive cock with her throat, causing her to gag and choke. He then lubes up her tight asshole, pushing a metal speculum inside to stretch her open. The nympho moans in pleasure-pain as he replaces the speculum with his thick dick, fucking her mercilessly until she cums, her screams echoing through the asylum's halls.
