I have been friends with Dave and Sarah since before they were married. I have always teased Dave about how Sarah would love my large penis (he has a smaller one). I recently realized that she can see all my texts to him and feel embarrassed. I would never act on it (Dave knows that) but she is tight and hairless with huge tiddys which is the exact opposite of my wife. Its a great fantasy for me because of the natural reaction my body has to her.
