Anybody recognize "Private Lessons"?

I just posted a large cel from something called "Private Lessons."

I can't find Private Lessons listed as an anime anywhere. It could be a video game (perhaps an H-game from its title), but I know nothing about video games.

It came with a certificate of authenticity from "CelWorks, a division of Central Park Media Corporation," and its copyright date is 1997. The cert calls it an original production cel.

Can anybody help?

Private Psycho Lesson

You can see more of this series at animecelcollector.com

Thanks for the link. I took a look at those cels, and I had also thought of Private Psycho Lesson (which I haven't seen).

But there are two problems with this. First, the artwork seems different. And second, I'm wondering why a printed certificate from a US company would call it simply "Private Lessons." If it were just me trying to make sense of a Japanese auction listing, I'm sure the title could have been just about anything. But if CPM was printing the thing out, you'd think they would know their own product's title.

No clue on the name change. Alex has a cel of a girl with the same uniform (You have to scroll to the your right).
If you look at his cels, you can tell there are different character designs for the same character.

He actually also has a sequence mate to the cel in question. Just scroll all the way to the end of his collection.

Also, I did some searching, and it looks like Private Psycho Lesson is called 個人授業 in Japanese, which just means Private Lesson(s). Maybe CPM printed out the certificates when they first bought the license, and then changed the title slightly to make it sound more risque?
