One's from the mid aughts, probably roughly '04 or '05, and one's from the 80s or 90s, not sure exactly when.
The earlier one is simpler to describe, because frankly I didn't get a chance to see much of it! It's pretty much just some dude watching TV late at night, playing with his TV remote. He hits a button, and something weird happens (I forget what, exactly.) So he tries another button, and a woman in either very little clothing (or possibly nothing at all) appears, and they go at it. Couldn't tell you more about it, except that I recall the woman being of generous upper-body proportions and that possibly it's British (saw it on TV at a British hotel in the early/mid 90s.)
As for the second, as with most of these things the "plot" was nothing spectacular; a girl just finishing high school shows up at her guidance counselor's office, and finds a note. The note points out that she's an abysmal academic failure and that college probably isn't in the cards, but that there's *one place* that might take her, see attached video to find out more. So she plugs in the VHS cassette, and of course it's some kind of porn school.
What struck me about this was that there was a noticeable lack of male talent. It starts off with a "teacher" and three "students" who are learning to get themselves off. The teacher is definitely older than the students, maybe by ten years or so? She asks them to make sure they have their "lab equipment" or somesuch, and they all pull out dildos. They, including the teacher, play with themselves by hand, then with the dildos. There's no real interaction between them that I remember, at least initially, but it's not exactly solo as they're there in a group. If it helps at all, the teacher had her own armchair off to the left, while I think the three either shared a couch or had their own separate armchairs on the right. I forget how that scene ends, but there's another bit a little further in with a bar stool. The film ends with the girl in the guidance office getting herself off and thinking that yes, this place just might be a good fit for her.
I had this round about '05 or '06, I think, but lost it a year or two later, and I've been trying to re-locate the thing ever since. Anyone have a name for me to go on? Please? :/
