In the few years after Mom passed away, my Dad often headed up to the family cottage to stay preoccupied with various projects. Dad was in his mid seventies and still handsome, his tall trim frame with his long legs and sexy ass were always a secret turn on for me. He did have a decent beer belly which I thought was very Dad-bod and sexy looking.
On one of my trips up for vacation at the cottage, Dad and I were left alone when my older brother and my sister had both gone back to their homes for several days. I was in my early thirties and single. My parents had found out I was gay years ago but were accepting and supportive of me. I wasn't flamboyant, rather just a normal guy next door type. I did have a secret kinky devious bend in me though that started back when I was a teenager and it involved voyeurism.
Our cottage was very rustic. It was built for spending the summers up on the lake. It had three bedrooms with a long pull-curtain for doors, an open ceiling and lots of knotty pine walls. One day when I was alone in the camp, I got a nail file from Mom's shelf and began to make spy cracks in between the boards of the adjoining bedrooms about waist high. I was careful not to make the viewing cracks too big as to be seen by the adults or any other relatives. Our camp was used by many extended family members so I wasn't too worried about anyone of them thinking it was me that had created spy holes in the wood. I can remember being very excited by the naughty little act I was making in the walls and had many visions in my head of all the family cock I might be able to catch. I did watch Dad take his bathing suit off and dry off once, soon after the spy hole creations and it was very hot to watch him being fully naked. His large cock and big low hanging balls got me very excited.
I never was able to spy on any other of my male relatives just due to the fact that someone else usually was always around and it was impossible to spy. Now that Dad and I were alone this particular time years later, I thought about those naughty cracks in the walls and found myself really wanting to see my elderly old man naked again.
