Also called "booth parties".
These have become VERY popular at BDSM parties in the last few years or so.
They are just what they sound like, a small room, (or rooms, depending on the size of the party) with holes in cut the walls. A person (sub) sits there, and services whomever/whatever is put through from the other side. There is a chair or a matt to sit or kneel on, tissues, a few towels, and a pitcher of cool (not cold) water with a glass. (your mouth and tongue get very dry after a while)
I think the holes are a bit bigger than the ones talked about before, because there is room for a hand to come in, to touch your breast, ass or pussy, or for part of a breast to be presented for kissing, licking and sucking.
It is a HUGE turn on, as I love being the center of attention, but gets very tiring after an hour or so, so most parties limit the sub's stay to no more than that, though are are exceptions, say for discipline.

Ahhhmmmmmm never mind.

Wanda takes the 5th, and doesn't describe any more.
