Ouroboros by songhyel has one!
I've seen it a few times but it's not super common. This is the one I remember most.

more stories should have 3somes like the one in the last chapter, by that i mean one person in the middle both penetrating and being penetrated, it's so hot. would love a poly yaoi where they have sex like that frequently tbh
does anyone have any other stories where a 3some like that happens?
