Cocktails 3 with Britni where she gets spat and loagied on through the whole scene by a bunch of mopes. She collects the spit and loagies in a pitcher and drinks the lot at the end. I don't know how available it is these days, it came out in the late 90's from Extreme Associates.

It also had a good scene with Veronica Caine and Brooke Hunter collecting guys spit and cum, mixing it with champaigne and drinking it out of a bucket...they didn't look to happy about it.
