What Can You Do With Your Girlfriend That You Can't Do With Me? - Stepson Fucks His Stepmom's Big

I was planning on fucking my girlfriend today, but then it started raining, and everything got ruined! I was trapped at home with my stepmom, who was obsessed with making us bond. She wanted to play board games and bake cakes. Hello? I was ready to get my dick sucked; no dessert can compete with that. At least, that's what I thought. Suddenly, her desperation for giving me a hard time made her change into the sluttiest costume I have ever seen! There she was, wearing red leather and showing off her enormous tits.
Then she said the most amazing thing she could have said to someone as horny as me: "What can you do with your girlfriend that you can't do with me?". Before today, I would have thought the answer was "a lot of things," but after she started making out with me and rubbing my dick with her boobs, I realized how wrong I was. Thank goodness for rainy days and my stepmom's pussy!
