Vintage Porn Prague Schoolgirl Threesome

Looking for a vintage porn video. It was a threesome with two schoolgirls and their teacher. One girl was tall with a mature face, but was quite underdeveloped, with small tits and a somewhat childish body, while the other was smaller, had a more childish face (great, slutty smile), but had bigger boobs, round and bouncy, and a bigger ass; she also had two pigtails. First, they sucked him off, then took turns riding him, then he ends up cumming between the two while the girls are on their knees. I clearly remember that the video had in the right corner that timestamp that old cameras used to have, it said something like "Prague 199X". I think it was something like 1995, maybe.
