It's hilarious that you thought you'd be able to hide your filthy little secret. It was only a matter of time before your girlfriend finds out, so really I'm just doing you a favor. Face it, you are obsessed with dick and there's no going back. And now that I know, I have demands: from now on you will obey me and become my cock worshiping slave. So unless you want everyone to know how thirsty you are for juicy cocks, I suggest you get with the program. Besides, deep down, it's what you've always wanted anyway.
