(Y/N is seen using some fake squirrel faunus features as he walks along with Blake, who hugs his arm between her breasts.)

Y/N: Are you sure your parents won't suspect I'm just a human?

Blake: Of course not. And besides, only my mom is still alive.

Y/N: What happened to your father?

(Blake gets silent as a flashback happens.)

(Ghira is seen havin sex with another woman, and Kali finds out.)

Kali: Bastard...

(Ghira stops what he's doing as he hears Kali's voice.)

Ghira: Damn it...

(Ghira tries to escape, but gets quickly pinned down by Kali, who kills him in a most gruesome way possible, even eating his insides, causing the other woman to puke, which draws her attantion.)

Kali: (smirks) You're next.

Woman: (scared) No... no... (gets pinned) NOOOOOOOO!

(Kali kills the woman as well, and the Flashback ends as Blake tells a lie.)

Blake: Um... that bastard Adam backstabbed him.

Y/N: Hmm... I see... (in mind) When I put my hands on him...

(Then they go to Blake's house, where Kali greets them.)

Kali: (smiles) Hello, Blake. Who is this cute over there?

Blake: His name is Y/N Rose. He's my boyfriend.

Kali: Good to know. I'll make some tea.

Blake: Take your time, mom.

(Then Kali walks away while swaying her hips, and Y/N turns to Blake, who smiles.)

Blake: So? How about you grab this Bellabooty while we're alone?

(She slaps her butt, making Y/N blush, and then she grabs his hands and makes him grab her ass. Suddenly they have a kiss, where Blake dominates him. Unbeknownst to them, Kali is watching the scene, and then she places something on Y/N's tea before bringing it to them. They stop the kiss and drink their tea. After drinking the tea, Y/N gets drowsy and Blake glares at her mom.)

Blake: Mom? What did you put in my boyfriend's tea?

Kali: Come on, Blake. You're not the only one who likes him.

Blake: Wait, you too, mom?

Kali: Yeah, and besides that bastard Ghira won't bother us anymore since I killed him and ate his insides once I caught him cheating on me.

Blake: Well, you have a point. Need a help to carry him?

Kali: To my room.

Blake: Right.

(Timeskip)

(Y/N is seen at Kali's bed, and he groans as he wakes up.)

Y/N: What the... (moans)

(Y/N moans as his member is licked by both Kali and Blake.)

Blake: I guess he already woke up.

Kali: Good. Now for the next part.

(Then Blake sits on Y/N's face while Kali inserts his manhood into her womanhood and starts bouncing. The room is filled with moans.)

Kali: Nya, now that's a good cock.

Blake: Better than my father's, right?

Kali: Nya, yeah. I'm feeling like in actual heaven!

Blake: (moans) That's why I love him, mom.

Kali: I love him too. Nya...

(They keep doing it during a few minutes until the three end up cumming, and both Kali and Blake collapse. They smile at Y/N with hearts in their eyes and shower him with kisses.)

Kali/Blake: We love you, Y/N.

Y/N: I love you too, Kali and Blake.

(Then they cuddle and close their eyes. That's how Blake's mother becomes part of Y/N's yandere harem.)
