(Y/N was just an adventurer, who somehow attracted the attention of the Fatui girls, who got so obsessed that they end up killing anyone who talks with him, especially girls.)
(Y/N is seen bumping into his friend.)
Y/N: Oh, hey F/N.
F/N: Hello, Y/N.
Y/N: How are you today?
F/N: I'm doing good, thanks for asking.
Y/N: That's nice. How's your team been?
F/N: They've been really great. It's nice working with them.
Y/N That's good to hear. Well, I'll go and relax for a while.
F/N: Okay, see you around.
(They walk into different paths, but then two Cicin Mages and a Mirror Maiden are seen watching them.)
Mirror Maiden: Just another stupid whore.
E. Cicin Mage: You know the drill.
C. Cirin Mage: I like killing whores.
(Then they proceed to kill F/N, and then the Mirror Maiden speaks through a comunicator.)
Mirror Maiden: We killed another whore who was trying to take Y/N from us.
????: Good. Now let's start Phase Two.
(Timeskip)
(Y/N is seen in his house relaxing until four figures showed up.)
Y/N: Uh... can I help you?
La Signora: (smirks) Yes, you can.
(Columbina rips off his clothes, exposing his naked body.)
Y/N: What the hell...
Columbina: Be quiet and just let it happen.
(Then the girls strip naked, making Y/N blush madly.)
Sandrone: Get ready!
Arlecchino: We'll make you submit to us.
(Then La Signora presses her boobs on his manhood while she sucks it off. Columbina sits on his face.)
Columbina: Lick it.
(Y/N licks Columbina while La Signora keeps sucking on his manhood. After some minutes, Y/N cums in La Signora's mouth while Columbina cums on his face.)
La Signora: That was good.
Sandrone: But we're not done yet.
(Then Sandrone positions herself above Y/N's manhood while Arlecchino bends over his face.)
Sandrone: 3, 2, 1...
(Sandrone inserts his manhood into her womanhood and starts moving. Arlecchino presses her ass on his face, and having no other choice, Y/N licks it.)
Arlecchino: (moans) Aaaaah...
Sandrone: Our favorite human...
(Sandrone moves faster as Y/N licks Arlecchino's ass harder.)
Arlecchino: (moans) Ah, my ass is feeling so good.
Sandrone: I haven't experienced such pleasure before.
(Then with some last moves, the three end up cumming. They lay down beside Y/N.)
La Signora: That was nice. How about another round?
Columbina: Good idea.
(They had their way with Y/N all day, and eventually he became the 12th Harbinger of Fatui.)
