Mom's a Cheater

You my son, catch me cheating on your father with another man. I spot you through the door as I'm getting fucked. I beg you not to tell your father but you insist that you will unless I suck your cock. I am so disgusted but I can't hurt your father so I reluctantly agree. I proceed to suck your cock when you notice me start to like it. I tell you we have made it this far so we might as well fuck. What a pleasant surprise, my son has such a great feeling cock!
