POV amateur anal with stepsister in exchange for my girlfriend

I'm not the kind of guy to play favorites. I mean, my girlfriend is amazing in bed and she's always down for anything. But when my stepsister came over, I couldn't resist the temptation to show her a good time. She's a total smoking hot brunette with a killer body and a mouth that's always ready to please. So, when she got on her knees and started sucking my cock, I knew I was in for a wild ride. But that wasn't even the best part. When she got on her back and spread her legs, I couldn't resist pounding her tight ass. It was like nothing I'd ever experienced before. And when she let me fill her up with my big cock, I knew I'd done the right thing. So, I guess you could say I got something out of it.
