This happened a few weeks ago. Our family was traveling for a wedding and he and I were sharing a hotel room. The wedding was at the hotel.
Towards the end of the night I go up to the room with a guy from the wedding to hookup. While we’re going at it my brother walks in with a girl also to hookup. We kind of argue, both thinking we had a right to the room. Eventually they decide to do it in the bathroom. But then after a few minutes they come out because it was too uncomfortable and get in the bed. So there we are having sex at the same time in beds right next to each other.
To be clear I don’t have a thing for my brother or any fetish like that. This just randomly happened and we went with it. Overall it was definitely an awkward experience but in a weird way kind of fun just because of how crazy it was. I kept thinking to myself, is this actually happening? We’ve basically just laughed about it since then. We have a crazy funny shared experience. But definitely won’t be doing that again lol.
