I (23f) and my brother (26m) come from a relatively normal background and have never indulged in anything like this before. However in mid November we both decided to follow one of our joined dreams together and do a ski season as chalet hosts.

Before we left we knew we were going to want to party and we were away from home so we both ended up breaking up with our then partners. We didn’t know what the living arrangements would be in the chalet for us two but we are close and knew we would figure it out.

Upon arrival we find our living quarters is one bed and living room with two single beds about 3ft apart with a large mirror at the ends of the bed and a bathroom. So, only a few nights into the trip … we’re getting settled and we’re drunk making friends and I can see my brother chatting to a girl. After some time he comes over and asks if it’s okay to bring her back to the chalet. He’s older than me and I think we both knew this was going to happen at some point. We weren’t going to both go 6 months without sleeping with anyone. So we both were as chilled about it as possible.

Up to this point we had been very much clothes in front of one another and getting ready one of us in the bathroom etc.

That night my brother explains to the girl our sleeping arrangements and she says she’s cool with it. So I’m lay in my bed… pretty much touching distance from my brother who is in bed with a girl he met that night. I think they thought I was asleep but after some time they started to kiss loudly and clearly start to have sex. They were respectful and tried to stay quiet but I knew what they were up to. The thought and sounds make me incredibly horny!

We had a quick chat about it the next day and we both agreed that we were okay with it. It’s natural and it’s going to happen with our living arrangements. He appreciated my understanding. I just warned him that he can’t kick off if I meet someone and he said okay.

In the weeks since it has all gotten a bit crazy !

The first 2 weeks he brought another 2 girls back, and the latest one he has grown a lot in confidence and showing off. He was above the covers of his bed, completely naked with a girl who was naked, doing everything you can imagine. I could see hear smell everything. It turned me on so much and I could feel myself getting wet and I’d touch myself. I saw him cum for the first time. It left me with a wave of ecstasy rolling over me.

The next week was my turn, I brought a guy back. We got straight to it. But something that had never happened to me during any sex before happened. As I knew my bro was awake and maybe watching the odd bit, I wanted to put on a show. I was spitting and gaging on the guys cock like I never had done before. It was so sloppy. I was moaning when he ate me out. And to top it all off, something I’ve never said before like this. I was being fucked in doggy quite hard, my tits bouncing and me moaning. I just turn and say to the guy ‘put it in my ass’. Idk what came over me. Knowing my brother was there turned me into a crazy horny slut. It was so hot.

Since then I’ve had 4 guys round and my brother has had 3 more girls. Each time we’ve been very open and able to see one another.

We have also changed from being very conservative to being completely nude in front of one another regularly which has been really fun. The latest is that I suspected he was having wanks in the bathroom- I brought this up to him and said it’s ok to do it out here … a few nights ago he had his first wank lay just 3 ft from me in the bed. I touched myself too! We are both finding the whole experience uncontrollably hot. And we have 4 months to go !!!
