Yeah, one of the founding members of Snctm was a guy named Phuong Tran (ethnic Vietnamese but born and raised in USA). Tran was actually kicked out of Snctm last year for unspecified 'depraved acts'.
Tran goes by the nickname 'Bunnyman'.
He's since moved on to a new swinger club but his photos give some insight into what is going on there.

There is a lot of bondage depicted; supposedly Tran has studied traditional Japanese knot-tying to a high level. I have to wonder whether he would always oblige when some of his partners asked to get out of their knots…
Also some of his photo subjects look pretty young (pic related)
