My wife is great, but she won't let me fuck her ass, and I really need to. Today, I found my chance to finally do anal, but it was not with her. My stepson was trying to get something from his window and got stuck. When I went in to help him, his big butt was facing my way, and I could hear it calling my name. My cock was getting so hard thinking about being inside him that I couldn't resist. I thought taking a picture of his big ass to jerk off later would be enough, but it wasn't. I started by grabbing his butt, and it was so firm that I was getting even more turned on and felt as if my dick was going to explode. Then, I sucked his cock to get him in the mood, and the taste of a man's dick was better than I could have imagined. It was finally time. I took off my pants and slowly shoved my cock inside his asshole. This is what I've been waiting for. I pounded him as much as I wanted to, and once he got unstuck, I could tell he enjoyed it because he took me to the bed and fucked me so hard my ass felt destroyed. I was so proud of him.
