I can't unsee it!
When i was maybe 10 years old I got up in the middle of the night to go to the bathroom. I thought everybody was in bed asleep, but I heard something downstairs. I got to the bottom of the stairs and saw mom and dad on the floor of the loving room. Both were naked. Dad was on his hands and knees, mom was behind him doing something and he was making a lot of noise.
Now a 17 year old realize what they were doing. Mom was f****** dad in the ass with a strap on! I envision it all the time when i look at them. POKE MY EYES OUT!
