So me and my girl have been together for 2 years now, since high school. She's really pretty and my brother has always eyed her up and made comments when she's around. I knew he was always interested in her, and it felt good knowing he thought she was hot.

One thing about me is that I'm into cucking. I have jerked off endless times over the idea of other men fucking my girlfriend, I don't even care who. I've even thought about her own dad fucking her right in front me to show me who's boss.

So a few weeks ago, I was visiting home from college and my girlfriend and brother were over. He bought us beer so we were all drinking outside, and we got pretty drunk. He started making jokes about how pretty my girlfriend is and eventually it escalated into him rubbing her thighs. She seemed to be into it and I was hard as a rock, so they kept going.

Eventually, he had his hand in her pants fingering her and kissing her while I was rubbing my dick through my pants. We all moved to my old bedroom and they started fucking while I watched.

It was insane. She's never done some of the things he made her do. He was choking her, slapping her rough, she rimmed him even, and he came inside her. I came three times watching them.

I haven't seen my big bro since then, but we've been texting a lot more lately. Weirdly I think it brought us together haha. We are planning to hang out again soon and I can't wait!
