I am her stepbro and professional masseur. So, I was giving my stepsis a relaxing massage, focusing on her perfect ass and sexy bare feet. Things got steamy real quick when she started playing with my cock through my boxers. Man, she was so turned on, she couldn't resist kissing it through my pants. But then, she took it to the next level and pulled it out, giving me the best blowjob of my life. I swear, her skills were out of this world. But you know me, I couldn't resist that forbidden round ass of hers. I had to pull her close and start dry humping her like there was no tomorrow. The feeling of her oiled-up ass against my boxers was just too much to handle. I ended up cumming right in my boxers, it was that intense. Trust me, you don't want to miss this taboo fantasy come to life!
