My dad and friends dads must have been more hard core.
The first mags I remember seeing were Hustler and Oui. Both had penetration and and lots of lip spreading going on.

I used to get hard everytime looking at a photo set of a skinny girl with average tits sitting on a guys hard cock that looked like an identical twin to Jim Morrison. I still get a little excited when I watch old Doors videos just thinking about how totally hot that guy was.

Fond memories.
