Happy Ending: Mafiamatsu X Reader

Meeting

You open your eyes. There's nothing but darkness. The place you are laying on is slightly wet, it makes you feel uncomfortable. In expectations of getting an answer you call out.
"H-Hello..?"
No one answers. Nothing happens. It's like you're stuck in a dark dream and can't wake up. You try your chance once again.
"Hello? I-Is anyone there?"
You feel something wet, slimy lick your cheek. You yelp and squint in fear. It's like... a human tongue. 'Where the hell am I?!' You ask yourself. You can't see anything and that makes it worse than ever. You then hear a thud, then a bigger one. It sounds like someone punches another person and they fall.
"OI! Get your damn mouth away from that girl!"
"Hahahaha! Can't help it! She's so tasty!"
As you hear them talk you start to feel your heart beats getting faster with a growing fear.
"You fools are scaring the girl."
"Heh, she's strong enough though. If she wasn't, she would die on the way here."
"Aah, I cant wait to take pictures of her!"
Your fear increases with the every word they say. You can't move.
"Let's get that thing off of her eyes. I want to see her shaking in fear!"
You hear footsteps coming closer to you. You don't know what to do. All you're doing is just lay there, not moving at all. As someone removes the piece of cloth, you see the bright light that is filling the room. It burns your eyes, so you close them reflexsively. After a few seconds your eyes get used to it and you start looking around at your surroundings. There are 6 men with similar faces, standing near you. They're strangely sexy. And they look like they fit all your standarts.
"Who.... are you?"
Words slip away from your mouth.
"Youkoso, Matsuno Mafia Uchi e."*

* "Welcome, to the Matsuno Mafia House."

The guy that has a red shirt and a black suit starts talking.
"I'm Osomatsu Matsuno. The leader of the mafia, also the oldest brother. We are the Akuma no Mutsugo*"
You don't understand anything. But, does it really matter? In order from oldest to youngest, everyone shortly introduces themselves.
"Karamatsu Matsuno. Second son. You should remember my name, Karamatsu girl!" He winks at you. "I'll be watching you."
"Choromatsu Matsuno. Third son." He smirks and asks in a deep tone. "Do you like to be humiliated?"**
"Ichimatsu. Fourth. I won't fail to pleasure you." He smirks as he pulls out fake cat ears from his back. "Ore no Neko-chan~"***
"Hey hey!! I'm Jyushimatsu! The fifth son! I like baseball!" The expression on his face changes in blink of an eye. "And knifes~"
"Todomatsu Matsuno! Sixth son." He giggles in an evil way and continues "I promise I won't forget to make our moments immortal with you!"
You have no idea where you are, why you are here and why they took you out of all people right?
You'll learn it very soon.
Ichimatsu runs towards you and injects your neck a kind of drug.
Last thing you see is everyone smiling and saying
"Oyasuminasa~i!"****

Introduction!
Hello! I got this idea from when I was too obsessed with the Mafia AU. I think it's kind of original? I don't know. But, I have really good ideas about the ending. This whole fanfic will have 8 chapters/parts. That's all you should know for now. Also, please excuse my English and grammar mistakes, since my native language isn't English.
*: "Evil Sextuplets"
**: Choromatsu has a humiliation kink in canon.
***: "My Cat-chan~"
****: "Goodni~ght!"
