You are my boyfriend and I am telling you about a guy I work with. He is always bragging about his big dick and how much better he is than you. I know he is exaggerating, and cannot be as good as he says, and I want to embarrass him in front of the girls at work!! I come up with a bet. I will seduce my coworker, and if I can make him cum first, then he has to pay for a vacation for you and and I. If he makes me cum first, then he wins, but I know for a fact that won’t happen! You decide to stay and watch us, because I reassure you that you have nothing to worry about. My coworker arrives, and his cock is even bigger and better than I could imagine. I try to hide the pleasure from my face, but after a while of him fucking me, I cannot help it! I cum all over his cock and lose the bet:( this is the best dick I’ve ever had, and he owns my pussy from now on. You are accidentally cucked and will never be able to fuck me again. It’s just you and your hand from now on! Loser.
