Stepmother's big ass helps me masturbate

I've always been a fan of big asses, and my stepmom's got one that's just irresistible. Her ample curves are a sight for sore eyes, and I can't help but fantasize about getting up close and personal with her. Every time I'm alone with her, I find myself drawn to her ass, trying to resist the urge to touch it. One day, I decided to take things into my own hands (literally) and I reached out to grab her big ass. To my surprise, she didn't mind and even encouraged me to play with it. The excitement got the best of me and my cock was throbbing with anticipation. I started jerking off, my hand moving rhythmically as I watched her ass bounce and jiggle. The sight of her big pussy lips and asshole only fueled my desire further. As I continued to stroke my cock, I released a hot load all over her ass. The pleasure was overwhelming and I knew this was just the beginning of many more steamy encounters with my stepmom.
