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.
So one day I had told my Dad that I was going out for a run and I'd be back in a little while. Dad had been working on one of his projects outside in the sun for a few hours and said he was going to get in the shower and then head to the store for an errand and get more supplies. He was just finishing up his lunch as I headed out the door for my run. As I stood out front the cottage doing a few stretches I saw him get up from the table and head into his bedroom after cleaning up his lunch dishes. He came out of his bedroom and headed into the bathroom with his towel draped over his shoulder and carrying his bathing items. Noticing he did not bring a change of clothes with him. I continued to stretch out my legs and I got a naughty thought in my head.
What if I were to quietly sneak back into the camp and go into Uncle Bud's room and wait for Dad to come out of the shower and spy on his naked body again through the crack like I had done decades earlier? He'll never know I'm in there and he said he was leaving for the store right after anyways, so it'll be perfect. My dick got instantly hard in my running shorts. I saw Dad close the bathroom door and I sneaked back into the camp quietly. I was so horny for what I was about to do to Dad, I took off all my clothes right there in the living room. I heard the shower turn on as I went into Uncle Bud's room and closed the bedroom door curtain behind me and patiently waited for Dad to finish his shower. I took one of the pillows off my uncle's bed and placed it on the floor so I could comfortably kneel on it while spying on Dad. I peered through the crack in the knotty pine and had a perfect view of Dad's room. I could see the area adjacent to his bed where he would be naked and drying off and putting his clothes on. My heart was banging in my chest. My whole naked body was quivering wildly.
As I knelt down by the wall I had visions of Dad soaping up his body. I was slowly stroking my hard on in anticipation of what I would see once he walks back into his room. Realizing it would probably very quick from him being naked to putting his clothes on I was a bit bummed but whatever, I was secretly spying on him and that was hot in itself. I decided to go into his room anyways after he left for the store and jerk off sniffing his used undies, so that was something to look forward to.
