Girlfriend (19) had an adventure at the bar and brought it home. FFM without me then MFM with me. picture included

Hey guys. So I'm going to share soemthing that happened to me couole weekends ago. But first here us a little background. So I'm 21 and my girlfriend (Megan)19. I recently found out that I like to share my girlfriend and that it turns me on a lot. The quick story on how that happened was I was hanging out with Megan one day while we were looking at pictures on here phone (she has thousands) and we came across 3 pictures that she completely forgot she had. the first picture was her on her knees with a massive cock in her mouth. Looking straight I to the camera pov style. Something much like this http://imgur.com/BBniQ2h . She was 17 at the time of the photo and I was amazed at how big this guy was. Had to be atleast 8-9 inched and a pretty good girth too. That was her ex boyfriend. As soon as we swiped to thay photo she quickly apologized and told me she forgot about it and was about to delete it when I stopped her and I asked to take a look. She was like "you really wanna see?" At that point I was hard as a rock and there was no turning in me back. I proceed with a yes. And she showed me and I asked if she had any more and she looked quickly and found two more. The other two was her in the doggy style position with his cock half way in her pussy and again it was a pov style photo. The third was the most dirty one in my opinion. She it was a picture of her laying on her stomach with cum all over her ass and a little on her back. She took quick note of my massive erections at this point. I remmeber her saying "omg your hard as a rock you find this hot?" And I admitted slowly but surely that was true . And from thay point on. Over the next few months when I got hang jobs she would include dirty talk about fucking other guys and I was loving it. Now back to the main story.
