Not a movie, but in the 2/1981 Chic there was an article on tranny porn, with not-quite-hardcore pix from porn mags used as illustrations. Some of it was M/T and some F/T; the illos showed Christine de Shaffer and Angel Cash in transsexual situations.
Never saw the movies but had some brochures in the middle 80s from Diverse that offered a couple of pix that were apparently orgiastic M/F/T groups — Orgy at the Poysinberry Bar is the only title I can remember. They were made by Kim Christy, who did a number of tranny, as well as femdom (sometimes with trannies), pix in those days. Annie Sprinkle was in Poysinberry, and if there’s any classic porn star who’s more likely to have fucked a tranny on camera, I don’t know who it would be.
