Humiliated by my Husband's Girlfriend: Becoming a Cuckquean

I thought I could just sneak in the side door and nobody would be the wiser about my night of bad decision making.
Boy was I wrong.
I never knew my husband Tom had a few tricks up his sleeve, including a new girlfriend. Together they punish me for my bad behavior, and I've never been so humiliated in my life. Stripped, spanked, and put in the corner while they make plans for the future, I hate to admit, I'm loving every minute of it.
I volunteer to be the live in nanny, and when she leaves her mark on me as I'm performing clean up duty, I know that my life is never going to be the same.
