so today i thought i would get to fixing that old laptop that's been laying around for a few years. the one my sister used for 4 years.

i did some testing and figured i'd should just reinstall windows to see how that might help out. so i yanked the hard-drive out of th laptop and hooked it up to my machine so i could back-up any needed files/documents. after a while of searching around and cut-pasting a few files, i decide to see what lies in the my video's folder. 

this is the part where i fuck up.

i open the folder, half-expecting to see a heap of unwatched jersey shore episodes and half-expecting to see nothing. 
instead i see a file. just a harmless avi. file named after the date of which it was saved. i give a good ole' double click on that file thinking it would probably be just a sample video or some shit.

nup. not even fucking close.

what appeared on my screen was so fucked up that it took me a little while to realize what in the name of fuck i was witnessing.

a room. not just any room, my sisters bedroom.
what was in the room you ask? just an ordinary bed.
and when i say ordinary, i mean it had my sisters boyfriend laying butt-naked on top of it jacking off at the speed of fucking sonic holy fuck.

he came. he came hard.

as soon as i realized what i was watching, i fucking slammed alt-f4 harder then my sisters boyfriend was slamming his dick. i immediately deleted the video and began formatting the hard-drive.

only some sort of high-powered laser beam could help me unsee that video.

and that reddit is how i fucked up and why i'm never going to be able to look my sisters boyfriend in the eye again.
