I remember back when I was little, I would spend my summer vacations over at my grandparents house. I would watch my Grandma knit and listen to Grandpa's old war stories. I spent many good years with them. Everything was great until one year when I was older. I stayed over for a couple of nights and everything changed. I remember it vividly, I was when I heard awful screeches and moans coming from my grandparent's bedroom. So I ran in as fast as I could. After seeing what I saw that night I would never be the same. They were both naked going at it like jackrabbits. My Grandma was sucking on my Grandpa's old dick and he stuck it in her over and over, it was so messy! They fucked all night long, and in every way possible. I was so confused, I called my mom and asked her "Why is Grandpa on top of Grandma?".
