Looking for the original film that inspired this video.

I watched a movie that was almost the same as this in the late 90's, so my memory is blurry. Is there another version of the first scene or a previous film that inspired this one?

This link is from Perverted #1 - The Babysitters (1994).

There are some details I remember distinctly from the video I saw: it didn't look so polished, yes, it was a vhs; here it has the first scene with the girl on cowgirl DP, while I remember it as a reverse cowgirl, the men's costumes were the same, and they were 5, too.

The second scene started with two men roleplaying as babies, one of them cries and the babysitter comes to the room and immediately starts doing oral to them.
