I did watch OZ on HBO a long time ago...J.K. Simmons played a prisoner on that show...He was a scary character...
There was a character, a female prison guard, who liked to have sex with inmates...Claire Howell...
"Howell is a sexual predator serving as a corrections guard in the eponymous prison Oz. She preys on all the men in her orbit, prisoners and guards alike, looking at them as mere human sex toys who exist solely for her to dominate." https://oztv.fandom.com/wiki/Claire_Howell
