I have a huge craving for a big cock. Not just any big cock, but my stepbrother's monster. His cock is so huge, it makes me crave for a cumshot in my pussy. I know I shouldn't, but the thought of his huge cock filling me up is too much to resist. I can't help but fantasize about it. I've been practicing my oral skills, hoping to impress him with my abilities. I'm not his daughter or sister, but I'm still hesitant. I know it's wrong, but the thrill of it all makes it even more exciting. I'm sure he'd love to show me just how big his cock is. I'm ready to suck and ride that cock. I can't wait to feel that cum inside me.
