Hooked On Cum

About a year ago my girlfriend asked .e to eat her out after I fucked her. I was a bit unsure if I should or not but she's such a good girlfriend I had to. I mean she blows me all the time even in the car whenever she is in the mood or whenever I ask her. Plus she lets me fuck her ass too and is awesome in bed. I always eat her out before we fuck anyhow and love her pussy. It's really sweet and she keeps it nice and smooth. What happened is that I found that I actually love eating my cum out of her pussy. It's like something we do every time we fuck now. I wish I could do it even more. I'm thinking about asking her if she would fuck other guys and then I'll eat her out after. But I never did anything like that before. I know she has fucked a lot of guys before we started going out, but she's been faithful to me since we started. She loves me and I love her. I just don't want to open a door that I might regret. But man, I'd eat her out after every guy fucked her even if it was like 10 in a row!
