I satisfy my desires by having sex with my petite stepsister who feels she is overweight

I have a fetish for women who are slightly on the curvier side, and my stepsister definitely fits the bill. Despite her constant complaints about her size, she's always up for some steamy action. One day, while I was studying in her dorm room, things took a wild turn. My step-sister, who's a college student, was scrolling through her phone when she stumbled upon some explicit content that got her all worked up. Seeing her in that state, I knew it was time to take matters into my own hands. I started off with some gentle caresses, but soon moved on to more intense action, satisfying her desire for bigger boobs and a bigger ass. As I pushed her to her limits, she let out a loud moan, culminating in a powerful squirt that left us both thoroughly satisfied.
