First polyamorous relationship!!!

I'm getting ready for my first Polyamorous relationship!

So far, I've been watching the videos here, fantasizing, while my bisexual wife met a friend who fell in love with me so much that she wants to move into a house with us.
Two families live together.
Can two families share an intimate life?
This already works between bisexual girls, the question is when I can join their intimate gatherings!
I had a girl-girl-boy relationship with my wife a long time ago, but I really want it again!...
