My stepbrother's huge cock inside my girlfriend

I was hanging out with my stepbrother, talking about college stuff when I mentioned my girlfriend. He seemed to be interested in her, and then things took a wild turn. He was boasting about his sizeable cock, and my girlfriend couldn't resist the temptation. She was already a big fan of his teaching style, and now she was about to experience his sexual prowess. They started getting it on right there in my room, my girlfriend moaning loudly as he pounded her. It was a sight to behold, his big cock sliding in and out of her tight pussy. He didn't last long, but it was worth it. My girlfriend was left spent and satisfied, her body still trembling from the intense pleasure. It was a moment of pure passion and desire, one that I would never forget.
