You might wanna read some old books. They have quite graphic descriptions of how slaves are treated and used in it. As well as the poses they should use to greet a master.
They're hard to find. Cause I'm lazy and didn't want to write them out, there's a LOT of Gorean novels, so I just copied a bit from wiki instead: The series has been variously referred to by publishers with several names, including The Chronicles of Counter-Earth, The Saga of Tarl Cabot, Gorean Cycle, Gorean Chronicles (Masquerade Books), Gorean Saga (Open Road Media) and The Counter-Earth Saga (DAW Books, for novels with a protagonist other than Tarl Cabot).
There's 38 in all. Didn't know they had started re-publishing them (noticed on wiki), so might be easier to get now.
But a Gorean slave pose...it'd be provocative. Kneeling, with their butt on their heels, legs spread shoulder width or a bit more, palms up with the hands resting on the thighs.
Aside from that. Platform shoes. UGHACHPTH. They should stay dead with bell bottom pants in the 70's. They look as stupid now as they did then.
