I have a confession - I got a glimpse of your cock recently and I haven't been able to stop thinking about it. You see, before I settled down with your step-dad, I was something of a size queen, and your step-dad's equipment just can't compare to what I had in the past. I thought I had put those desires behind me, but seeing my step-son's big cock rekindled them and now I desperately need to be filled up by someone with that kind of size. I'm so close to going out and finding some random big-dick bull, but I really don't want to cheat on your step-dad and ruin our marriage. Can't you help step-mom out and satisfy my craving for big cock at home so I don't have to step out on your step-father? You can even cum inside me
