Nat, it's possible
I had done a room with a friend and Girl Robot.
But, it's not possible to have 2 same robots in a same room
I don't try to invite Girl Robot and Boy Robot, but why not
only Robot Girl can join groups, not Robot Boy, who is basically a free male. Aaaand this is damn useless if you want to test a pose and can't find a male partner to do it! and yes, you can invite only 1 Robot Girl…..
i think it's time for some upgrade: add Robot Shemale, make Robot Boy join threesome to test them and, why not!, give us the chance to add 2 for any kind, so we can freely test a threesome!
