I really want an off-collab where Mumei, Fauna, Kronii and Ame meet up at Ame's house and each cook something for the others while they all laugh cutely together. Then afterwards Mumei suggests that they should sing something together and they agree.
Before long the other three start to feel light-headed until eventually Fauna passes out. They quickly end the stream but then Kronii and Ame pass out as well. Mumei gags them and ties them to various pieces of furniture before scheduling another stream, acting as if they've figured out what's wrong and everything's fine now.
After the stream starts Mumei explains that she put them to sleep and she plans to inflict various "batsus" on them. Kronii is the first to wake up and struggles after seeing herself as well as her friends tied up, as everyone watching the stream hears her muffled screams. Mumei giggles saying she can't hear her, and removes her gag. Kronii starts yelling at her, confused and enraged, but Mumei forces herself onto Kronii and shuts her up with a deep kiss, reducing her words to breathy moans. "You're so cute when you're scared", she says with a smile, before punching Kronii in the face strong enough to draw blood from her nose. She continues beating her up and laughing until she can barely hold up as her words are reduced to painful, stuttery whimpers.
Startled by the commotion, Fauna and Ame finally wake up, shocked at their surroundings. As Fauna freaks out, falling backwards onto her chair, Ame stays silent, trying to keep calm. "Hi Ameeee", Mumei says as she looks at Ame with a smile. Ame stays silent, refusing to engage with Mumei. "Not in the mood to chat huh?", Mumei says as her smile fades from her face. Ame keeps ignoring her and looking around for anything that could help her, before feeling a tap on her shoulder. "Looking for this?", Mumei says as Ame turns to face her, with her metal baseball bat in hand. Ame barely has time to react before Mumei strikes her across the head.
Ame falls down in clear pain, but still verbalizes nothing other than pained breaths. Mumei pouts in response. "Hmph. Ameeee, I really wanted to hear you screaming!". Mumei paces around the room, thinking. "Oh I know! This will make you speak up for sure!", Mumei says as she walks to the other side of the room while Ame's eyes follow her. As she taps the clear glass of Ame's fish tank with the bat she continues: "You know, I wonder what would happen if I did that to this instead!", she says, before striking it with all her force and shattering the glass, spilling all of its contents to Ame's horror.
Ame lets out a muted scream as Mumei laughs in ectasy "Now that's the spirit!". Mumei grabs a pea puffer from the now destroyed tank and walks towards Fauna, lowering herself to the ground and hovering her gaze over her friend's own fearful eyes. She cups her cheek with her right. "And you, my cute little Fauna", she says as she removes her gag, "Don't think I've forgotten about you". Forcefully opening her mouth she deposits the little fish into it. "Come on Fauna, you look hungry!"
Fauna's eyes widen as she realizes what's going on. She looks at Ame's distressed and tear-filled face as she begins to tear up herself. "Mumei! Why are you-" she tries to say, before being slapped by Mumei. "Fauna, eat, it's not that hard", Mumei says while walking to the other end of the room. "Or would you rather eat this one instead?", Mumei says as she forcefully grabs Wellington tail, parading him in front on the three girls. Ame's eyes widen in response as she scurries towards Fauna, grabbing her hand and looking at her with pleading eyes. Crying while looking at her friend, with painful cries in her mouth, she starts to chew.
Mumei stares at the pair, delighted, as she lets out another giggle. "Remember Fauna, you have to finish all your food!", she says as Fauna continues chewing, her tears speeding up. As she finishes her last, painful bite, she opens her mouth to show Mumei that she is finisshed. "Good job Fauna", Mumei says as she approaches her and pets her head.
As Fauna struggles to remain calm, with loud whimpers all over the room, she feels her gag reflex act up, and hurls the contests of her stomach all over the floor. "What the heck Fauna, that's gross!", Mumei says as she turns to Ame and ungags her. "Come on Ame, clean it up", she says as she pushes her head down, hovering it above Fauna's vomit. Ame starts to lick the floor, resisting her own urge to vomit until Mumei is satisfied. "Look Fauna! Ame cleaned up your mess, you should give her a little kiss as a reward!", Mumei says as she pushes their heads together, forcing them into a lip lock, both of them collapsing onto the ground afterwards.
Mumei looks back a the computer they're streaming from. "Oh hi!, sorry, I really lost track of time. Is the stream even still going?", she says to the audience.
"Anyways", she says.
"I'm really lucky to have such wonderful friends!"
