Unexpectedly giving a blowjob to my friend's aroused husband while visiting her

I had to visit my best friend and when I came, her husband was not at home. As we were talking in the kitchen, he came out of the shower and saw me. He asked me if I wanted to give him a blowjob. I was surprised but I decided to do it because I always wanted to have sex with him. So, I started sucking his big dick and then my friend came out of the bedroom and saw us. She was shocked but she decided to join us and she started sucking his dick as well. We all had sex together and it was amazing. The man came two times in a row and we all enjoyed it a lot.
