Was in summer school in college and 2 buddies and I went to the drive-in movie to see the "sex flicks". None of our girlfriends were in summer school so we were very horny. This was back in the day where seeing a nice pair of boobs on the screen was enough to get us wound up. We were totally unaware that there had been a Supreme Court ruling that sex could be shown on screen as long as it had "socially redeeming value". A movie came on called 101 Acts of Love. We assumed it was like all the others,a lot of teasing and brief flashes of flesh. A couple was on a couch making out and the scene would switch to a woman discussing what was taking place on screen (i.e. the socially redeeming value part). Back to the couch and the action became heavier. It went on for a few minutes, then more discussion. Then the woman in the scene began rubbing the crotch of the man. We went wild!! Suddenly she unzipped his pants, reached in and pulled out a nice sized very erect cock. We couldn't believe our eyes. The rest of the movie was an instruction video of the couple having sex on a glass table with angles from above, below etc. They showed positions we didn't know existed. I will never forget that movie. It wasn't long before hard core porn became very common but that was our first introduction to it. I would give anything to see that movie again tho I'm sure by my jaded standards now it would seem very tame.
