Leave your mark on me

Pairing: Alpha! Ushijima Wakatoshi x f!Omega!Reader Summary: (Y/N) and Ushijima grew up with each other. (Y/N) isn‘t a fan of the whole Alpha/ Omega society, which often enrages Ushijima (little miss (Y/N), often gets herself in trouble with other alphas). Both Omegas and Alphas have to get injections to keep them from going into heat/ rut. Due to a missed appointment, (Y/N) is going into heat, but don‘t worry, Ushi is obviously there to help hehe. Warnings: smut, slight mentioning of blood (> after marking)

A low growl escaped his lips as he read your text message.

Ushijima has told you plenty of times not to come over to the boys dormitories, knowing how some of the other alphas could act towards an omega. But you just never listened to him. He was sure that it was because of your attitude towards the whole society.

His brows furrowed as you didn‘t show up, letting him wonder where you were. 

She should be here already, Anger and worry seemed to take over.

He let out a groan as he exited his room, noting how your scent lingered in the air. However, it was different than usual. 

Ushijima knew that something was off, picking up his pace he rushed towards the source of the scent. As he came around the corner, he noted a couple of alpha‘s surrounding a small material room. 

The scent that radiated off of him was enough to scare them away, watching how they quickly hurried away, he walked up to the door. 

„(Y/N),“ he called, his voice sounded low, „it‘s me,“

„U-Ushijima,“ you groaned.

„(Y/N), open the door,“ he demanded, „are you hurt?“

„I‘ll break the door open,“ he said as he didn‘t get a response.

However, the door quickly flung open.

You were babbling incoherently as your heat got the best of you.

„(Y/N),“ he leaned down, „are you-,“

Your scent was too much to handle, „are you in heat?“

Your eyes locked, giving him a good view of your face.

Your pupils were blown, skin glistening while a subtle pink dusk was set on your cheeks.

„Shit,“ he cursed, „come here,“ 

He picked you up, rushing back to his dorm, he tried his best to ignore the slick that was running down your legs and onto his hand.

“I-It‘s too hot,“ you muttered, feeling like your skin was burning.

„Sssh, it‘s alright,“ he said with a soft voice as he entered his room.

Ushijima kicked the door shut before he carefully sat you down onto his bed.

„(Y/N),“ he tried to get your attention.

He reached his arm out, cupping your cheek, „(Y/N),“

„Hm,“ you looked at him with half lidded eyes.

„(Y/N),“ he said, his voice sounding commanding „let me be your alpha,“

„W-what,“ you looked at him with big eyes.

You wanted to press your legs together, hiding your slick covered thighs from Ushijima. But your body has long made the decision of taking him as your alpha. Hence why you spread them, letting the alpha see your most intimate part. 

He clenched his jaw as he tried to contain himself.

„I will be yours,“ he said, “and you‘ll be mine, Omega,“

You averted your gaze for a second before locking eyes with him. You nodded your head reluctantly.

„Say it, Omega,“ he said.

You were engulfed by his scent, feeling your slick pool in your underwear.

„Just say it, and I‘ll help you,“ Ushijima demanded.

You watched him with narrowed eyes as he brought his hand up to cup your cheek. His calloused thumb brushed over your skin. It felt comforting and yet his touch felt like it was burning.

„T-take me, alpha,“ you whined, giving into your heat.

That was all the alpha needed to hear. Ushijima closed the distance between the two of you, clashing his lips against yours. 

Oh, how many time‘s he‘d imagined to kiss you - to devour you. 

He kissed you hungrily, a low growl rumbled in his chest as he wanted more now that he finally had his omega.

The one he always wanted to have. 

„A-alpha,“ you whimpered, tugging at his clothes as you wanted to feel his skin against yours.

He swiftly removed his clothes discarding them onto the floor. Your lips parted as a shaky breath spilled over your lips once your eyes fixed on his large cock. 

He moved to his previous spot, leaning in for another feverish kiss before he forced his tongue into your mouth. Your tongues were battling each other before he dominated yours. 

Before you could realize it your shirt was torn into two pieces, its buttons flying across the room. 

He couldn‘t get enough of you. He knew that you were seemingly in heat, but why was he so out of it.

Ushijima wondered if it‘s because you finally surrendered to an alpha - to him. 

He pushed you back against his bed, his wide frame making your legs spread before you wrapped them around his hips.

You were grinding against him, needing to feel some kind of friction. His cock pressed against your wanting heat, evoking a soft moan from you. Only the thin fabric of your underwear was separating you.

Ushijima‘s large hands were hiking up your skirt, pushing it up to your waist.

You needed him just as much as he needed you. He couldn‘t contain himself as he saw you in such a state. 

Although he loved the sight in front of him, he cound‘t watch his omega suffer.

„Alpha,“ you moaned into the kiss, „I need more,“

His chest vibrated as a he growled against your lips. He parted from you, fixing his gaze on your soaked underwear. 

„These are in the way,“ he said, hooking his fingers into the soft fabric of your panties before ripping them apart. 

He pushed two digits into your cunt, feeling your slick coat his fingers. You threw your head back against the pillow, finally having something inside of you. 

However, satisfaction didn‘t last for long as you needed more.

„M-more,“ you pleaded.

Ushijima used the slick on his fingers to coat his hard length before he aligned his cock with your entrance. He slowly sheathed himself into you, watching your face contort in pleasure. 

Your gaze met his as he filled you up, feeling how his tip hit against your cervix. Although he was huge, he just filled you up perfectly. Like his cock was made just for you - for your pleasure.

Ushijima thrusted carefully into you a couple of times. Your arms instinctively wrapped around his wide shoulders.

A low moan escaped his lips as he felt your slick gush out, coating his cock before it trickled down onto his balls. 

He rested his forehead against yours, feeling his hot breath hit against your skin as he spoke. 

„I wanted you for such a long time, omega,“

„A-alpha,“ your brain was incapable of forming any words as it was filled with lust. 

His lips trailed down to your neck, where his lips brushed over your sensitive skin.

He parted slightly, watching down at you with hungry eyes.

The pace of his thrusts picked up, being more rough than before.

His hands were tightly holding onto your hips to keep you in place as he pounded into your wet cunt. You felt the knot tighten inside of you as you were getting closer to your edge. 

„C-close,“ 

„Cum all over my cock, omega,“ he commanded.

His forehead was glistening, noting how a bead of sweat trickled down on his temple. 

It took only a couple of thrusts before your orgasm crashed over you, turning you into a trembling mess.

„Just like that,“ he praised, his voice low. 

Ushijima wasn‘t done with you.

Instead of stopping, he picked his pace up, drilling himself into you as you were putty in his hands.

Your nails dug into his skin as you held on for dear life. The sharp sting spurring him on.

He placed a couple of kisses on your neck before his teeth lightly grazed over your skin, making you shiver beneath him.

He wanted to bite down into your flesh, marking you as his. But uncertainty washed over him since you were in no way or shape in the right mind - or at least so he thought. 

Your orgasm seemed to lower the effects of your heat. 

„M-mark me, if anyone, I- I want you to be my alpha,“ your voice was shaky as you replied in between moans and whimpers.

He groaned against your skin. 

Ushijima let his teeth rake over your scent glands before he bit down, his teeth sinking into your skin. You whimpered, but the pain just added to the pleasure you were feeling.

The act of marking you seemed to be enough for him as he was nearing his edge. He kept his teeth in your skin as he literally fucked your brain out, filling the room with the lewd sounds that spilled over your lips. All he could think about was the fact that you‘re finally his, belonging to him and only him. 

He bit down even harder as his orgasm washed over him, growling against your skin. His rough and unsteady thrusts pushed you over the edge for a second time, letting you come together with your alpha.

Your insides were painted white as he filled you up to the brim before his knot swole and tied you together.

He snaked his arm between you and the mattress, carefully maneuvering the two of you so you‘d be laying on top.

Your head was resting on his chest, listening to his heartbeat. 

You turned your head towards Ushijima, locking eyes with him, „I really do want you to be my alpha,“ 

His lips tugged into a soft smile as he brought his hand to your face, „I will always take care of you, my omega,“

Ushijima has taken care of you for as long as you could remember. Ever since you befriended him when you were a little kid. You knew that you were safe with him, allowing yourself to surrender to him.

He felt proud to be the only alpha you‘d ever get involved with.

You slowly drifted off as exhaustion washed over you. Ushijima hugged you tightly as he laid there happily. 

By the next morning everyone knew that (Y/N), finally had an alpha and that it was none other than Ushijima himself.
