My stepbrother's perversion leads to unprotected oral sex and cum in mouth

My stepbrother has always been a bit of a perv, and I've been trying to avoid him for a while now. But when he came over to my place the other day, I found myself in a bit of a sticky situation. You see, he's got this thing for big asses, and he couldn't resist the urge to give mine a little lick. At first, I wasn't too keen on the idea, but as he continued to shower my ass with attention, I found myself getting more and more into it. Before I knew it, we had moved on to some doggystyle action, and then he was unzipping his pants and thrusting his big cock into my mouth. I tried to resist at first, but as he continued to pound my throat, I gave in and let him finish all over my face. It was a wild ride, but one that I won't be forgetting anytime soon.
