Mystery TS Movie with Juliana Di Primo

Back when high-speed internet was a luxury (say around 1999 or so) I came across a movie, or rather a scene for a movie that I've since lost track of, and I can't even find the title.

The scene was basically Juliana Di Primo (young, before any implants) with four other t-girls who I didn't recognize (two are a bit plumb and blond, two are skinny and with dark hair), and they basically play around with each other for 15-20 minutes on a couple of couches.

I've looked at this filmography and it didn't help much. Anyone have any ideas on what title this might be?

On edit: Oh... the file was called something like Sonhos De Bonohos... but that doesn't help much.

If I remember correctly, there was a birthday cake involved?

Nobody? Nothing... It's a classic!

Don't know if it helps at all, but I've got a screencap of the scene in question.
