Alpha!Osomatsu x Omega!Reader

(And like the Alpha!Karamatsu story, this is based of @Kyosein's comic)

It's been a few months since you have now been living with the Matsuno brothers, your parents were on vacation and since they were very close to the Matsuno family, they asked if you could stay with them until they came back. You had some trouble understanding who the Alphas, Betas and Omegas were in the house but it didn't take a lot of time: Osomatsu and Karamatsu being both Alphas, Choromatsu and Jyushimatsu being the Betas and leaving you, Ichimatsu and Todomatsu being all Omegas. You were very close to all the brothers, but you were closer to specific brother, Osomatsu, the greedy and handsome brother, the other brothers kinda respected him but were annoyed when he always asked them for money to go to the pachinko and were surprised that you would spend more time with him but you just liked him, he always protected you from other Alpha's on the street, took care of you when you were sick, made you smile and laugh, you just adored and gave Osomatsu the attention he wanted and needed but today was different.
You were all together at home, minding your own business when you started feeling very hot, and sensitive making you trip and almost fall to the ground.

Y/N- grunt* w-what the fuck is happening..?

You couldn't breath, you felt so much heat around like the sun was around you, you were very confused when you remember that it was "that" time of the year, you were in heat, Choromatsu stopped reading and looked at you.

Choro- Is everything alright Y/N? You seem sick.

Y/N- Y-Yeah, I am a-ok!

Ichi smelled the air and realized what was happening, he got up and helped you stay up while Todo was still too busy with his phone but knew what was happening.

Ichi- Come with me, I think that there are still suppressants for your heat.

You two went to the bathroom and searched in all the cabinets, but for your surprise, the suppressants were all gone. Ichi thinked for a moment, knowing that if your scent got stronger either Kara or Oso would immediately act up and start fighting again.

Ichi- Ok, you stay here while me and Todomatsu-nissan will buy more suppressants for you.

Y/N- W-What about Osomatsu and Karamatsu..?

Ichi- We will tell them to go away, it isn't that hard to put them out of the house anyways. You go to our room and get yourself confortable because we might take a while.

You nodded and went to the brothers room, laying down in your futon and putting all the blankets over you. Ichi went down again and whispered what was happening in Todo's ear, he widen his eyes and told him that they needed to go immediately.

Jyushi- What is happening? Is Y/N-chan ok? Is he dying? Can I keep his stuff?

Choro- C-Calm down Jyushimatsu, im sure he is ok right?

Ichi- He is just in his heat, me and Todomatsu will go and buy suppressants for him. As for the rest, you can leave and go to pachinko or do something else.

Osomatsu wasn't even hearing since he was listening to music when Choro smacked his head and took his headphones off.

Oso- What the fuck?!

Choro- Out of the house now.

Oso- What did I even do?!

Jyushi- Y/N-chan is in-

Karamatsu covered Jyushi's mouth and smiled.

Kara- Y/N-chan is in luck today!! He won some money and is giving it to us so that we can spend!

Oso smiled and got up, putting his headphones around his neck.

Oso- Really? That's amazing! I need to thank him later!
