FX Meister Olaf Ittenbach providing the special gore effects on the set of German independent horror and porn director Andreas Bethmann's "K3: Prison of Hell".
Knowing YouTube's strict guidelines I had to edit out in advance the first half of this making of to take out all the BJ scenes and most of the direct shots of her crotch area and only uploading the last half where it is covered in fake blood so it doesn't show too obviously because i don't need another obscenity claim from easily offended people as this video is only meant to showcase the making of the effects.
