My Bully is my Stepmom's Home Care Patient

Darren, the football star and asshole from my first year in college, suffered a hand injury. As luck would have it, my stepmom's agency assigned her to take care of him. I don't think that's supposed to involve her taking care of his tremendous hard-ons, but that's what happened on the first day. She was convinced he needed "around-the-clock care" and before I knew it, he was staying at our house, in my room. Now I'm on the couch, listening to her pleasure his dick. When he showers, guess who gets to help him clean his cock? She says it's a lesson in humility, like Jesus washing feet. I don't feel like it's the same thing. But Darren owns her now. He's taken over the house, and they're even trying for a pregancy...
