My Girlfriend’s Big Surprise [m/f], [cheat]

Using a throwaway as a lot of different people know my username. My girlfriend, (24/F) who we’ll call Deb, and I (30/M) have been together for a little over a year and a half. I would honestly describe our relationship as perfect. After both being in previous relationships that were terrible in pretty much every way, we couldn’t appreciate each other more. On top of that, we are incredibly attracted to one another. She’s amazing…5’6″, 115lbs, athletic build with smaller perky breasts and a very round ass, the juiciest lips, short dirty blonde hair and the most beautiful big hazel eyes.

Our sex life was always great. We really discovered ourselves sexually, having been in fairly boring relationships previously. I felt like the luckiest guy in the world getting to explore her body with her…letting her become an expert at sucking me off, teaching her how to actually cum, exploring the joys of anal. I still haven’t totally figured out why…but I started fantasizing about her with other men. I’ve always been very into porn, so my best guess is just imagining her, as beautiful as she is, being in a porno. I never really put a face or a personality to anyone she would actually be with…it was always just fantasizing watching her sucking on a really big cock, or fucking a very in shape well hung guy. The thought of her ACTUALLY being with another man made me incredibly uncomfortable…so it remained a fantasy, one that I eventually shared with her.
