My dad used to hide the old VHS tapes back in the day. They were of gangbangs and lots of the oldschool dp's that clearly got him going. His tastes got me into it. On my birthday one year when I was younger he walked into my room in and dropped the video in front of me and said "enjoy.... I think you always get better use out of this than me." He flashed me a dirty shit eating grin, winked and slapped my ass then walked out of my room.
After that, I was finding his old Picture and People magazines floating around... (the harmless lads magazines of the day). Then once he knew I was reading them he started buying the harder stuff. Occasionally his used magazines ended up in my room in the back of my wardrobe, He knew where I hid things so I think he left them there intentionally for me to read in the end.
