EDITED MARCH 7th, 2023

Ok, so I’ve been so into the omegaverse and Kagehina so I decided to make a one shot. It’s my first one and I’m sorry if it sucks but honestly, I’m very proud of how it came out.

It is a smut so no one under the age of 18 should be reading this. This does take place during the time skip when they are part of their Division 1 teams which are the Schweiden Alders and MSBY Black Jackels if y’all didn’t know. This is also a few weeks after their match against each other.

Now I give you…

‘Kageyama Help Me’

Summary: Hinata starts his heat in the middle of the night and pleads to his alpha to take care of it

Parings: Tobio Kageyama x Shoyo Hinata

Genre : NSFW/ 18+/ smut

Rating: NC-17/Mature

Warnings: language, smut, impregnation

Word Count: 900 (I know it’s fairly short but I’m still learning about the omegaverse. I actually would like to write a full story about these two in the omegaverse but I have no ideas 🤷🏻‍♀️)

Hinata woke up in the middle of the night, he was sweltering and very uncomfortable. He kicked off his blankets and got up from the bed and started stripping off his clothes. His breathing soon turned labored and he collapsed to the ground.

The sudden thud woke the alpha in the same bed. “Hinata?!” Kageyama exclaimed in worry and rushed over to his fiancé’s side of bed.

He found his omega collapsed on the ground on his hands and knees stripped from his clothes except for his boxers.

The middle blocker looked up at his setter as he got hit with a strong seductive scent. It was the same as Hinata’s usual scent but a lot sweeter and stronger. Kageyama knew his omega was in heat.

“Haa…K-Kageyama…h-help me.”

“Where are your supplements?”

“I-I…ha…I don’t want them. I-I…want you. Please Kageyama, help me.” Hinata cried.

“What if I knot you though?”

“I don’t care, please just make it stop.” Tears were now streaming down the redhead’s face.

He really wanted Kageyama to take care of him. It took the blue-eyed alpha a moment to think about it but he agreed to help his fiancé.

Kageyama picked up his omega and laid him on the bed and pulled down Hinata’s last article of clothing as his erection sprung out as he was soaked from top to bottom.

“Look how wet you are baby.” Kageyama says and rubs his thumb up and down Hinata’s entrance as his breath hitched.

He rubbed it nice and slow until he slipped two fingers inside his omega. “Ah!” Hinata moaned out as he shivered.

Kageyama wiggled his fingers inside Hinata as he lets out more moans as he made his way up deeper into his partner. “HNGGH!!” Hinata moaned out so loudly as he shuddered.

Let’s hope their neighbors didn’t hear the submissive omega’s moan that just came out of his mouth.

“Guess I went a little too deep...I found your uterus.” Kageyama says, a smug look on his face as he wriggles his fingers against it.

“Aah…ahngh…ha…!” Is all that came out of the male’s voice as his body started trembling. “Kageyama stop teasing me! Please, I need you inside me. I’m begging you.” Hinata pleads to his alpha.

“Begging me huh?” Kageyama says and licks his fingers of Hinata’s slick. “Mmm, so sweet.”

“Please Kageyama fuck me, I’m desperate. Make it stop.” Hinata begs even more, Kageyama was taken aback by the sudden swear word that came out of his omega’s mouth.

He smirked and chuckled, “Well when you talk like that I can’t say no to you.” He tells him and gets off his mate and removes his pants and boxers then spread’s Hinata’s legs apart.

Kageyama then slowly slips his fully erected member inside his partner as they both let out a moan and threw their heads back in ecstasy.

Hinata’s body starts out as a quiver then he starts trembling. Kageyama then presses his lips to his omega in a passionate kiss that soon turns into a make out session as Hinata moans into the kiss and wraps his legs around his alpha for deeper penetration.

Kageyama kept thrusting into him as he kept kissing him with such passion and lust. He then makes his way down his mate’s body with his lips as he licks him from the neck and to his chest, not breaking the sexual interaction between the alpha and omega.

He licked his nipples as Hinata let out some more moans, grabbing handfuls of Kageyama’s hair as he kept doing what he was doing.

He then moved his lips back up to Hinata’s neck and kept on thrusting into him at a perfect pace and perfect angle.

“Ah!! Aaaah!! Anngh!” All that and so much more came out of the omega’s mouth.

“Such sexy little moans coming out of that pretty little mouth of yours, let’s hear more but louder. I need you screaming my name.” Kageyama says and thrusts into him deeper and harder hitting his uterus.

“AAHHH! Haa! Ah…Kageyama! Aah…” Hinata moans out as he digs his nails into his alpha’s back being sure to leave scratches.

“Ah! It hurts, it hurts Kageyama.” Hinata cried out as tears ran down his cheeks. “It got bigger…it got bigger inside me.” Hinata also said and that’s when Kageyama realized he knotted his omega.

“Shit…I knotted you, I’m so sorry.”

“No, no it’s ok it just…” Hinata starts as he winces in pain, “hurts…really hurts.”

“I know, I know my love sh…I’m so sorry. Come on, let’s switch positions.” Kageyama says and they switch where Hinata is now on top of him.

He lays his body on his alpha as he cries into him in pain. “Don’t move my love, it’ll get better soon.” Kageyama says stroking his omega’s hair and kisses his head.

The setter and middle blocker just laid like this until morning came. Kageyama sent a text MSBY’s coach and told him that Hinata wasn’t feeling well so he can’t make it to practice.

Kageyama then sent a text to his Schweiden coach and said that he needed to take care of his omega since he wasn’t feeling.

Both coach’s allowed that so the alpha and omega had the day to themselves to recover from what happen last night.

Fin 🧡🏐

And that’s the end of it, I was thinking about writing a part two to this when Hinata finds out he’s pregnant or should I even make him pregnant? What do you guys think?
