So basically it is il/legal drugs and/or gangbangs, depending on interpretation, and probably the only way to find out is to ask the girl. Or not.
Best bet if you want a gangbang is to look for a gangbang
If you don't care ask for a party girl
And if you want to do substances take your own and prepare for the wrong girl to get the hump or keep it to yourself !
Party girl means does mean involving substance in the real world of looking for escorts. Not necessarily illegal could be legal highs ! To summarise girls that don't mind being out of it in presence of strangers !
Can get messy and glad I don't any more !
