I "found" on of my girlfriends in the basement at a home party fucking a guy... It was the best and most erotic thing I ever had seen back then and I struggled hard to come up with something I could say to tell her that I just loved to see her getting fucked without being a total pervert, but before I could say anything the guy shoot his cum in my girlfriend and I didn't dare say anything too her about it before 3 weeks later, when I came over her on a new home party while she sucked the same guys cock. I don't know if it was bc she had sucked him for awhile are if it was shock over seeing me in the doorway, but he came in my girlfriends mouth right then and there and for many years it was one of my most sexy scenes I had seen cos my girlfriend just kept on sucking him until he was empty and swallowed his whole load while she knew I was standing there watching her do it. I was steady with that little super slut for 3 years after that... First guy she fucked was my best friend after that, then about a year before I broke up with her I lost count at 17... Most of them fucked her at least 2 times, my best friend fucked her almost as much as I did. I sometimes miss her over the years, coz all a man needed to do was ask her and she would gladly fuck him.
I learned a lot about myself, my jealousy, arousal and how much I can take from her... and sometimes wonder about how my sexlife would have been if she hadn't showed me that I like to se other men fuck my girl friends, and later wife's... I didn't get it back then, but it was actually her pleasures that turned me on... Like it is when my current wife fuck her lover and I see her face dissolve in total pleasure over her lovers shoulder when she get an orgasm on his cock... It is so hot and lovely...
