Noticed this game has the swinging tag, so I would assume there must be netorase content or something similar. How is the content for that in this? Is it very low and only very minor or is there a decent amount of it? Also can you share the trap characters?
On the tag list: "A couple allowing one or both partners to have sex with a third party."
Meph, a demon who runs a hotel full of demon bois, whores out many of the characters you corrupt if you make a deal with him. Another boi, Robin, is also used to spread a feminizing effect to others.
I'd also argue that Andrea's content counts, as her husband is mentioned several times to be supportive of her doing porn with the player.
Depending on your definition of a couple, characters who sell out their friend (madison/abigail) or family (mary/margaret) might also apply. That said, the majority of the content is player x other character, so swinging isn't a major focus of the game.
Hope that helps!
