Being a Mistress of Repentance would be such a dream job.
Everyday, you'd be tasked with whipping and spanking cuties, from blushing novices to hardened veteran Sisters coming to you of their own will, having judged themselves guilty of a grave offense. After a few months, you'd know how every Sister in your detachment sounds when she screams and moans in pain.
Even in battle, your role would be to ride with a dozen almost naked beauties, whipping them into a bloodthirsty frenzy. And when you finally make it to the heretic lines, you'd surely find a cute female cultist or two to whip into submission.
