Step Mother makes me pay neighbor girl and her friends for every time I think about them while I am masturbating

My former Step Mother Pat stopped by a few days ago to tease and humiliate me for a little while. She was making me admit to some fairly humiliating things when she asked how often I fantasized about my neighbor Jenni and her friends. I admitted that I thought about them pretty often, she laughed and then asked when was the last time I had fantasized about one of them. I told her I was dreaming of my neighbors friend when my Step Mother arrived. She asked if I had permission from the girl I was fantasizing about, I said no and a she suddenly had a wicked smile. I knew I was going to be put through something extremely humiliating by way she laughed as she walked outside, a few minutes later she returned with the Jenni and made me tell her all about how much I beat off thinking about her and her friends.
