The prison guard, Dana, takes her role as dominatrix seriously, commanding the two submissive inmates, Claire and Emma, to strip and assume degrading positions. She orders them to rim each other, their natural boobs pressed together, before presenting their asses for her inspection. Dana inserts a butt plug into Emma's virgin hole, making her squirm, while Claire watches, eager for her turn. Dana then brings out a massive dildo, stroking it against their asses, teasing them before finally pushing it deep inside. The girls gasp at the intense anal stretching, their bodies trembling as Dana brings them to the brink of prolapse.
