Acronyms

I'm researching a HDH that I'm thinking of seeing. On her website, she lists the following activities:

GS
Light, medium or heavy restraint (given and received)
Groups
BKK
GB/Tag Team
POS
Dom/Sub
Slave
BDSM (Light/Medium)

Out of this list, I can't figure out what the following ones mean. I've googled them, but I get nothing that helps. Help me if you can please.

GS
BKK
POS

Thanks,

Golden Shower is the only thing that comes to mind.

No clue on the rest

Since she listed GB's, I'm betting that BKK is bukkake. Not sure what POS is.

Well I'd have to see the context. It could positively outstanding service...haha.

I think we've got 2/3, if she upcharges for that Zed I don't know what to think.

Perhaps it is a typo for SOS

Or from Urban Dictionary Two possible 4 answers I am guesing #3?

28.pospound off session as in jerkin it so that guys have a secret word to say just like girls
My pos today couldn't have been any better.

POS could mean-- Pee On Sub. That is assuming GS refers to Golden Shower where man pees on girl.
