The film that inspired "Rollergirl"?

This might be a tough one. Maybe impossible. But someone in 'the biz' said I should try asking in here...

Paul Thomas Anderson describes watching a porn film which went on to inspire "Rollergirl" in "Boogie Nights". Here's his description:

“There was a girl on roller skates...and the plot was that she’s rollerskating down the street and stopping at each house, looking in the window, and watching everybody fuck. That was the plot. And that’s where I got Rollergirl from!”

Some footage of PTA discussing her origins with Charlie Rose: https://youtu.be/CY_IAT3FejY?t=11m44s

Does this sound familiar to anyone? I'm working on an article about Boogie Nights and would like to be able to identify which film that was.

Thanks in advance!

Someone at The Rialto Report suggested "Pizza Girls", but admitted it doesn't really match the description. I checked it out and, they're right, it doesn't. The Pizza Girls are on skateboards. And no window peeking.

Close but no (Freudian?) cigar.

So, what you do you think? A girl on roller skates stopping at each house, peeking in thru the windows... Sound familiar at all??
