I was always a bit of a rebel, and my stepsister was no exception. She was a naughty vixen with a big ass that just begged to be spanked. One day, I caught her playing with herself under the table, her chubby fingers stroking her pussy. I couldn't resist the temptation and decided to join in, giving her a little push. She didn't mind, of course, and soon she was on her knees, taking my big cock into her mouth. It was a sight to behold, her fat body writhing as she gave me a deepthroat blowjob. I could feel every inch of her, her soft lips and tongue exploring every inch of me. It was a steamy scene, one that left us both completely satisfied. And the best part? We got away with it, our secret safe from prying eyes. It was a wild ride, one I wouldn't trade for anything in the world.
