German K-9 Sex Show

[prn4r]

A guy I hooked up with once told me about a bar or club he had gone to in Germany (I'm guessing it was probably 15-20 years ago and I think he said it was in either Berlin or Cologne), that had a live sex show involving a twink getting fucked and knotted by a dog.   Does this sound familiar to anyone?  I'd love to hear more about this, since my hook up didn't elaborate too much.  Did this type of show exist before bestiality was made illegal in Germany?  What exactly occurred during a typical show?  How was the twink presented, was he into it, or was it more of a master/slave type situation?  What was the atmosphere in the bar like when the show was happening?
