I wanna say this was a Frank Thring - Silvia Saint scene... but I don't remember.
Description: it's a scene where the cameraman (/ one of the crew) asks for and gets a bonus blowjob?/****? as it was his birthday (I think he actually showed his ID to prove it)?
I'm pretty sure I watched it on Private / Spice TV in the mid 90's or early 2000's.
