Replying...
Intro. Sarah, your wife since they gave her that Great Dane, no longer pays attention to you and all her attention is on Rocky, that's what I call the dog. One day, you arrive at the house early, you go in and he's not there, you go up quietly to surprise your wife and you start to hear moans, you get sad when you hear the moans and then you slowly open the door to see who he's cheating on you with, but you freeze when you see his lover, who is Rocky the dog.

Sarah and her best lover Rocky
