wrong door dear~ [sara x ei x yae] [discontinue]

Since yae and ei both aren't humans meaning they have heats while both of them can't mate, but it all changes when Sara went to the wrong room. What happens next? Unknown... (this has smut so leave if your not comfortable with it, and don't come after me with this ship I know it's not canon or anything is just a ship if you don't like it then move on)

ALSO I DO NOT OWN ANY OF THE CHARACTERS THEY ARE FROM GENSHIN IMPACT
