2000s-2010s Private Sex Partners (BB) near shoreline - remember this?

This is a reach but I'm hoping someone from Seattle might remember.

In the 2000s to 2010s, there was a guy (I want to say he went by the name Seattle Horse - not the Horse Market parties) who held regularly sex parties at his home which I believe was in Shoreline or the University District.  I'm not sure that they were explicitly bareback but I have a strong sense that was a core component.  Getting invited required you to know someone who had been to one, and he kept the email distribution pretty tight.  

I want to say that there were about 50-60 people at each party, plenty of daddies/bears but a fair numbers of guys who were like me at the time - in their 20s / early 30s, twinky looking guys.

I went once, had a good time, and would have gone back but the dates of the subsequent parties never worked out.  

Does anyone remember this?  My Seattle friend and I were talking about today and we both had similar memories but light on details.  If you remember this, DM me or comment below.

I went a few times. Bred and got bred.  Once got pounded by the Horse himself.

So it was "Seattle Horse" right?  We both had memories of this but we couldn't really recall specifics.  It was a long time ago.
