I never imagined that I would find out that you’re gay by walking in on you watching gay porn! It’s no surprise to Me that you also love big cock. I’m the sluttiest step-sister in town and I know all about how to get a man’s cock off with My mouth. No sib-ling of Mine is going to be bad a giving head, so I am going to teach you how to suck cock by inviting one of My boy toys over and we can take turns sucking his cock. I want you to be the best at it like me and what better way for Me to bond with you than to share My skills with you.
