My future omega wifu (Alpha!Osomatsu x Omega!Reader)

Another alphas scent

Kuro picked you up by your classroom since you two need to give the teacher a form for a trip you want to take over the club. So you two are slowly on the way over to the teacher office.

"And you really think he let you go?" Kuro ask confused. "Well, if I give him all the affection for a day he would say yes. But I think my dad would be more worried about me." You laugh flustered while thinking of how your father would react if you ask him.

Kuro hums and says: "I guess an alpha who didn't mate with his omega yet is more worried." "You couldn't be wrong."

Osomatsu walks out of the classroom he talked with Choromatsu about the next lesson. When he saw you talking with another boy he got jealous. But Osomatsu remembers that you told him by dinner yesterday that you and the president from your club need to ask the teacher who's responsibility for the clubs in school something.

You three passed by in the hall, but when Osomatsu gets the scent from another alpha in his nose he stops walking and his eyes widen. Because this scent belongs to the boy next to you.

"Okay, if it works I'll buy with Shin the snacks. Ayaka will take care of what exactly we're doing and you-?!" A hand grabs your wrist from behind and pulls you quickly back. You stumble and hit the body from the person behind you.

You look over your shoulder and Osomatsu narrows his eyes at Kuro. He in return turns around. "Is there a problem, Mr. Osomatsu?" Kuro ask calm, but is narrowing his eyes at Osomatsu too.

"Eh?" You pulled your arm quickly away so nobody of the students or maybe a teacher can see that Osomatsu holds you in place. What caused him to get confused and a bit scared since his alpha side is on stage now.

"Let's just go, Kuro. Before we didn't catch Mr. Takishima anymore." You glare at Osomatsu before pushing Kuro forward. Your glare told Osomatsu "we-talk-in-your-office-at-lunch-time".

~At lunch~
Osomatsu sits on the couch in his office while you stand in front of him. Arms crossed over your chest to show him that you aren't here to tell jokes with him.

"So?" "So what?" Osomatsu ask a bit annoyed. Not looking at you. "Why did you pulled me away from Kuro in the middle of the hallway?" You ask a bit angry.

"(Y/n)-chan, he's a alpha! I only tried to protect what's mine!" Osomatsu defend himself. "First, I know that Kuro is a alpha. Second, I'm not a thing. I can understand that you want to protect me Oso, but-"

"No you can't understand!" You flinch from Osomatsu's sudden voice raising and his mad tone. "We never mate with each other! I never marked you! You are a omega! How could you understand anything?!"

You stare at Osomatsu with widen eyes. It's the first time he yelled at you like this. Of course you two had fights before, but Osomatsu never yelled at you like this.

" ... " "I ... sorry." Osomatsu put his elbows on his knees and lays his head down into the palms of his hands. You walk the few steps over and sit down next to Osomatsu. " ... Oso?" He hums and look with his eyes a bit at you. "Um ... w-what do you ... m-mean with m-marking me?"

Osomatsu quickly looks up to you now. On your face is a huge blush while you look embarrassed down to the ground. Osomatsu's eyes widen. " ... I have to bite you in the back of your neck (y/n)-chan." Osomatsu says calm while he gets slowly closer to you.

"Um..." You play nervous with your fingers while the blush only gets worst. "...b-but please be gentle." With that being said Osomatsu grabs your wrists and pins you down in the couch. You squeak from his sudden movement and before you knew it Osomatsu turns you onto your stomach.

He push your hair aside and pulls your uniform a bit down. Your breath goes shaky while your neck starts to turn red. Osomatsu licks his lips and his eyes getting tinned red. "Ah-!" Osomatsu bites down on your neck hard.

To be honest you don't really know how to feel right now. You feel scared and at the same time it feels good. You start to whimper when Osomatsu bites deeper in your neck. Causing blood to come out already.

"O-Oso..." You whimper out. Osomatsu pulls away and licks over the bleeding mark. You shiver from the wet tongue who licks the warm blood away. Osomatsu hums and nuzzle his face against your cheek. He only earns a whimper from you.

"Hey." You hum and look a bit at Osomatsu. "Wanna skip the next lesson with me? I can teach you a private lesson~." Osomatsu purrs in your ear.

Osomatsu was sleeping on the couch this night again.
