I was in the shower when I heard some strange noises coming from the bedroom. I went to check it out and found my boyfriend fucking my best friend. They were both completely naked and my friend was still wet from the shower. I was shocked and upset, but my boyfriend didn't seem to care. He just kept fucking my friend while I watched. I couldn't believe what I was seeing. My friend is supposed to be like a sister to me and now she's getting fucked by my boyfriend. It was a weird feeling, but also kind of exciting. I decided to join in and we all started fucking. It was a crazy threesome with my friend getting fucked by my boyfriend and me. It was a wild ride and I enjoyed every minute of it.
