The Cheating Husband

You are David Grayson, a married man for 21 years. And in those years, you discover that you are not into women but into men.

And after you discover your sexuality, you caught yourself in an affair with a man who shares the same lust and desire you have.

It's wrong, you say to yourself.

But everytime you are near him, you lost all your sanity and want to be him.

The question is, how long will the affair last?

(Note: Your sexual position depends on the love interest that you choose.)
