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

PE class

Ayaka and you throwing eachother the basketball over. The girls playing basketball while the boys playing soccer outside. That's why Osomatsu watch the girls inside the gym hall while Karamatsu is watching the boys. Osomatsu is only watching the girls because of you. He likes it when you wear the dark red sport clothes from the school. It makes you even more cuter in his eyes.

"Hey (y/n)?" Ayaka ask with a small smirk. You hum and throw the ball to your friend. "Can you spell 'me'?" "Huh? Um, okay? M-E?" "You forgot the d." Ayaka smiles innocently. "Eh? There's no d in me."

Ayaka throws the ball back to you. "Not yet~!" Ayaka smirks evilly. "Eh?!" You flinch and your face turns red like a lobster. But you looked at Ayaka in this moment, which means you didn't looked at the basketball. "Urgh!" The basketball hit your head what cause you to fall down. "Oh shi-! (Y/n)!"

When Osomatsu hears your name getting called out in a panicked voice he quickly looks into this direction. The other girls walking now over to you since you fall down with a loud thud sound. Osomatsu holds back to call out for you, but he quickly runs over to you.

"What happened?" Osomatsu tries to stay calm. "I only teased (y/n) a little and then she didn't looked at the basketball when I throw her him back." Ayaka explains worried. She didn't mean to hurt you or anything.

'Looks like she doesn't need an ambulance.' Osomatsu sighs quietly in relieve. "Okay class. I'll get Mr. Karamatsu and-" But Ayaka has suddenly a great idea. "I'll bring (y/n) to the nurse office, Mr. Osomatsu!" "W-What?" Before Osomatsu can react Ayaka lifts you up like a bride and walks quickly away. Osomatsu is screaming in his head. Because he wanted to carry you so you would feel so loved from him that he gets from you the right to touch you wherever he wants.

~And then...~
Since sport was the last thing on Osomatsu's and your timetable Osomatsu headed over to the nurse office to pick you up. Ichimatsu wasn't there so Osomatsu looked around before he shut the curtains from the nurse bed where you laid in.

Osomatsu sits on a chair next to the bed and pokes your cheek softly. Smiling a little while watching you drool a bit. 'I'm so lucky to call (y/n) my own~. When I think back I never thought she would be really marry me. It's somehow really funny how things were between us in the past.'

You hum and open your eyes a little bit. "Hello sleephead~." Osomatsu coos with a happy grin. Chuckling from your cute sleepy face. "Oso...?" Osomatsu hums while you roll from your back to the side. Facing Osomatsu's legs now. "?"

You reached a hand out and took Osomatsu's one hand softly. "Ayaka told me you carried me to the nurse office. Thank you." You mumble sleepy and close your eyes again, but your cute smile is making Osomatsu blush. He put his elbow from his free hand down onto his leg and lay his chin down into his palm. Looking away from you.

'Shit. If (y/n)-chan isn't stopping with looking so cute I might attack her one day because I can't hold back anymore. ... But when we mate I don't need to hold back anymore anyways~.' Osomatsu smirks a bit from the thought of having you under him. Begging for his cock inside you under tears mixed together with the sweet smell of an omega.

"Oso?" You ask shyly. Osomatsu hums and looks with his eyes back to you. "Um ... s-since you um ... w-were so kind ... y-you can ki-kiss me." You mumble shyly into the blanket. Osomatsu's eyes widen.

He leans down and you shut your eyes tightly. Waiting for the kiss. But Osomatsu sees your nervous face that he can't help it. He needs to tease you. So Osomatsu leans down to your ear and whispers: "I'll kiss you when we're home (y/n)-chan~. But you don't know when~." "E-Eh?!"
