- Be invited into a polyamorous relationship with an existing NPC-NPC couple after a few threesomes

- Suggest to a normal couple to turn their relationship into a poly one with you joining in, if you already had an threesome encounter with them in the past, or done something sexual with each individually.

- New "Organize a poly swingers' party" available at home specifically for you and other poly couples

- New "Gather all poly partners" action available at home that brings all of them to you, each of whom can be interacted with (good for having them taking turns on you while the others watch etc)

- New "Hang out with poly partners" action available at most public location types in the game, which will improve their attraction to you and can lead to random events under certain conditions like:

+ Come across someone you know, who gains or loses rapport depending on their perversion 

+ Two of your lovers getting particularly intimate with each other

+ A stranger being drawn to your arrangement and expressing a desire to join

+ Another poly group suggesting a fun party
