You think you know everything about your mom and dad, but as I found out six days ago, I really don't.
They've gone off on vacation, leaving me to look after things. I thought I'd tidy up one of guest rooms we use for storage. Moving one box out of a cupboard I discovered lots of self copied dvds with titles on them. Most were holiday pictures and home family videos, but three of them had, one, two and then three questions marks hand written on them.

After sorting the room I got curious about the dvds and decided to put one on the player in the lounge. I shouldn't have, because now my whole perception of my parents has changed. The first dvd had my parents making out naked on their bed. My dad penetrating my mom from behind as she knelt up on the bed. Then the focus altered and in walked a guy I didn't know. He was also naked. Getting on the bed, he got behind my father, put something on his palm and begun to rub his hand between my dads ass cheeks. Seconds later the guy was actually fucking my dad, as he was still inside my mom.

Looking back I should have turned off the machine, but I didn't and kept on watching. In the twnety or so minutes it played, I saw both my mom and dad getting fucked by the same guy. Only when he pulled out of my moms ass, could I see how well endowed the guy was.

The second dvd was if anything a little tamer, as it had my mom and two other women making out on their bed, as my dad was giving direction, it was still shocking to see my mom openly enjoying licking another womans pussy, but it was nothing to the third.

The third was a whole different scenario as it wasn't at our home, but in what looked like a hotel room. There must have been lots of people in the room, as the person filming panned between different couples all having sex with one another. Only when the camera moved to a small seat did I see my mom sat masturbating on it. She was sat with her legs wide apart watching my dad taking anal sex from a much younger guy, and by the sounds of it not only was my mom encouraging the young guy to fuck my dad harder, but he was loving being fucked.

Watching it was almost hipnotic and I found myself becoming increasingly fascinated. Only when I noticed myself touching my own pussy through my shorts, did reality strike and I stopped playing with myself and stopped the film.
I've not watched them again and in a few days time they'll be back home.
I cannot get the thoughts of them having sex with other people out of my head, and knowing that everything I thought about them being true, probably isn't. They're certainly not the tame suburban parents I thought they were.
