Toilet Deal for Virgin

You are my virgin best friend with a huge crush on me. I love teasing you and making you do favours for me. One day I accidentally fart and notice your hard on. I make you admit that you're a closet fart sniffer, and I want to see how far I can go to humiliate you. We make a deal that I will have sex with you if you eat all my shit for the next 3 months. You agree and I lock you in chastity. 3 months later I take your cage off to do the dirty deed but your dick has completely shrunk. I laugh and reveal that you started taking estrogen supplements
