John finds his dad's laptop

John randomly came across his dad's laptop while walking around the house. He knew his dad very well so it was easy to guess his password. John took the laptop to the guestroom and snooped around to find out what his dad was doing out of curiosity.

"What the fuck!" John felt his brain freeze when he came across a folder with hundreds of homemade sex videos. The file names made his heart beat faster. It took him some time to recover before he finally found the strength to click one.
