My stepbrother penetrates me while I'm playing a video game

I was chilling in the living room, playing my favorite game on my stepbrother's computer when he walked in. I didn't think anything of it, we are pretty close. But then he asked me to bend over and spread my legs. I was taken aback, but I didn't want to get in trouble so I let him. He unzipped his pants and started to stroke his big cock. I didn't know what was going on, but I just kept playing my game. Then he pushed his big cock inside of me. It hurt at first, but then it felt good. He fucked me hard and fast, making me moan with pleasure. When he finally finished, he pulled out and shot his cum all over my pussy. It was a weird experience, but I can't say I didn't enjoy it.
