My best friends brother

So im a freshman in High School and my best friend is the youngest of three and her older brother is a senior and we had eaten some special chocolate nothing too harsh but it was fun and we were hanging out with him and I was laying on his bed next to him and he was making like little movements that REALLY turned me on and I've liked him for a while, and then my Friend and I went to sleep and I wanted desperately to stay in his bed with him and fuck but I didn't and ive never been more frustrated in my life I like him SO much it hurts
