My sister and I went too far with our game and ended up having sex

My sister and I always loved playing games, but this time we decided to take it to a whole new level. We were in our dorm, and we were feeling adventurous. We started talking about sex and before we knew it, we decided to take it to the next level. We stripped down and started touching each other. It was a bit weird at first, but then we got into it. She gave me the best blowjob of my life and then we started fucking. It was amazing, we were both so horny and we couldn't control ourselves. I fucked her hard and she loved every second of it. We didn't care who heard us, we were too busy enjoying ourselves. After we finished, we were both exhausted but satisfied. It was the best game we ever played.
