Dad said I was 6 or 7 when I caught my older sister being fucked. My sisters were 10, 13 and 14 years older than me and the 2 oldest were already married when I witnessed my sister getting fucked in her bedroom. It was a summer Sunday afternoon and my parents, older sisters, brothers-in-law and nieces and nephews were in the yard under the shade tree. The sister 10 years older than me was sitting in the porch swing with her boyfriend and I was just there. I didn't fit in with anyone so I was playing when I went in the get some water. I heard my sister and her boyfriend walking upstairs and knew their steps ended in her bedroom. I went upstairs to my bedroom and heard my sister moaning. Her bedroom door was closed so I peeped through the old key hole and she was laying on the edge of her bed with her dress-tail up over her chest and her boy friend was massaging her pussy. He was kissing her and her legs opened wide as he stood and unzipped his brown suit pants and hauled out an uncut hard dick. My sister raised up and put it in her mouth. I was shocked as I knelt in the hall looking in the key hole of her room. She laid back down and he laid on top of her as he pulled her legs out with his hands and she began to moan.

I ran downstairs and as I was about to go out the kitchen door dad was coming out of the bathroom. I said I was coming for you something is wrong with (my sisters name). I was up the stairs and peeping through the key hole by the time dad got to the top step. Dad opened the door as I looked and saw the expression on dad's angry face. He said (boyfriend's name who was laying on my sister) and he stood quickly turning with his hard dick sticking out his zipper. I was looking (standing beside dad )as I noticed his dick was glistening and white stuff on my sisters brown pussy hairs.

Dad told me to go to my room, close the door and not come out until he came for me. I knew by the tone of dad's voice he was mad. I looked out from my room as dad pushed the door to my sisters bedroom close behind him. I waited a minute and heard nothing so I walked back to the door where I knelt down and looked in the key hole again.
My dad was standing at my sisters spread legs and her boyfriend was on his knees with my dad's dick in his mouth. I had heard a slap so I knew dad has popped him up beside the head. Then, dad pulled him back and turned toward my sister as his knees bent and dad hunched toward my sisters pussy. I heard her moan real loud as my dad's ass began to move back and forth. It was a short time before dad stood up and moaned himself. He turned back and told the boy friend to clean it off and he want back on my dad's dick. I heard dad call him a cock sucker and told him to get out of his house.

I ran to my room and closed my door just as my sisters door opened and I heard the boyfriend going to the steps never to see him at our house again. It was quiet for the longest and I heard my sister (I knew her steps) walking down the steps as dad opened my door. He pointed his finger at my face and said if I ever told anyone he was in my sisters bedroom I would regret it the rest of my life. My dad had no idea I had seen it all, but I had.

I was 18 and had just graduated high school when dad and I went fishing one day. We talked about the family and when my sisters name came up I told him what I saw. He was angry at first as he began to explain he had one too many drinks that day, mom was going through the change and he was horny - his justification. I said, I could care less because I have beat off a million times to that memory. Dad was taken back finally asking did I want to fuck my sister? I said, hell no ! I want to suck your dick and I have already sucked (my sisters boyfriend). Dad had no idea I was gay and was, for the first time in only a few, he was speechless.

We said nothing else for a week or so until one Saturday morning we were home alone and dad asked if I really wanted to blow him. I said yes, so he dropped his pants and I sucked my dad's dick. By the time I put it in my hand it was hard as stone and when the head hit the back of my throat my dad unloaded so much cum it ran out my mouth while I was swallowing. Dad said it was the fastest and most he ever cum in his life and said it was mine anytime I wanted it. That was the only time dad fucked my sister but he fucked my mouth and ass until he passed away at 84 and, other than my sisters boyfriend, no one ever knew me and my dad had a secret.
