My girlfriends first [MFM] threesome

A little background. My girlfriend is 5’5 long brunette hair, 38DD boobs with a great butt. Everywhere we go dudes break necks to look at it. We been together for 3 years and have had one drunken threesome with her girl friend that was moving. Sucks because i barley remember it.

Well it all started one day laying in bed naked with each other i asked her whats her biggest fantasy. My girl is a freak but very shy about it. I couldnt get it out of her. So she asked me and i replied with well you gave me my first 2 girls threesome its only fair i let you have 2 guys giving you attention. Her face was happy but shocked. She asks youd be okay with a random dude fucking me? I said of course not. Cant be random but someone we know. She says that would be awkward to ask someone we know.

Couple days later she was telling me how her good friend lets call him ryan. Was doing really good. And got himself an apartment 5 minutes from us. Ryan and my girl have been friends for over 10 years. They never hooked up. Kinda shocking to me as hes a good looking guy.
