Pushing The Boundaries

Some moments in life you will never forget, or even be able to put into words properly. The moment you first watch your wife or girlfriend pleasuring another man with her mouth is one of those. The feelings that come with it can't be understood unless you've been there.

That feeling of awful sickness in your stomach. The feeling of knowing this is so wrong, knowing you should put a stop to it. That awful moment when you see that he is noticeably bigger than you, and there's nothing you can do to make her unsee it!

But the most awful part isn't any of those things; the most awful part is when you look down and realize you have a massive boner. 

Why does the thought of your wife's mouth wrapped around another man make your body react in that way?

I didn't even really want to do this. It was just a stupid drunken game that came about because she caught me watching some cuckold porn a while ago. 

Now she's determined to push our boundaries as far as she can, and there's nothing I can do to stop her while I'm stood there with a hard-on.
