Okay, I'm really hoping someone will be able to help me with this. I've been trying to track down a particular movie for at least the past 15 years or so. It's the first porno I ever saw -- I was only about 10 or so -- and to this day I can still remember the scene that gave me my first orgasm ;)

I could swear that the movie was called "Behind Part 7", but Googling that title gives me absolutely nothing. The scene I remember most clearly begins with a guy lying on a bed wearing a wifebeater, while a blonde chick wearing panties (a thong, maybe) sucks him off. After a few minutes, he says to her, "Why don't you take that off so I can do you like you like." After she finishes sucking him off, they fuck (big surprise, huh?)

Another scene has a couple fucking on a glassed-in patio, while there are people walking by outside.

I'm sorry that I can't be more detailed, but after all, it was nearly thirty years ago, and those are the scenes that I can still remember (especially the scene with the blonde chick and the guy in the wifebeater; like I said, that one made me cum for the first time!)

There's also a more modern series I'm trying to track down as well, but I can't quite remember the title of the series. Each "episode" of the series features a guy filming girls while they try on various panties for him while he plays with his cock. He rubs his cock all over their panties, then they fuck (usually beginning with their panties still on). I've tried Googling "Panty Sex" and various forms of that title, but I've not had any luck at all so far. I'm thinking the series is only a few years old.

Thanks in advance to anyone who can shed any light on these movies for me!
