Breed – Suna Rintarou x Male!Reader (omegaverse AU)

*some aspects of this oneshot might be different to typical omegaverse lore. I’ve put my own twist on it.

It was that time of the month again and you woke hot and feverish, swimming in a pool of sweat a few hours after your alpha, Rintarou, had left for the day.

“Oh nooo,” you wailed internally, “he’s going to come home and smell that I’m in heat and that will be it! Non-stop sex for the next week or so.”

Rintarou, was a kind alpha. He was quiet and somewhat distant but he made sure you were cared for. Although he wasn’t the cuddly type whenever you went into heat that would change… dramatically.

Instinctively you got up and dragged the bedsheets and cover off the bed and into the wardrobe, making yourself a nest in there where you would spend the rest of the time that you were in heat, preparing for any possible babies that might be coming your way.

Although you had been through about 5 heats with Rintarou he hadn’t bred you yet and you were quietly hoping that this time, amid the torrents of sex that you knew was coming, he would mate you and make your quiet life of two … into three.

“I’ll make a really nice nest. Maybe that will make him want to breed me,” you thought as you busied yourself packing the pillows around the edge of the wardrobe and fluffing up the doona in the middle.

You were so busy getting yourself ready that you didn’t hear Suna come home and you were down on hands and knees in the middle of your nest when he entered the bedroom.

He took one deep breath in and knew immediately that you were in heat, that soft sweet scent wafting around him and making him giddy with sexual fervency.

“Y/N,” he said in his usual even tone, but a hint of urgency in his voice.

You jumped with fright and spun around, still on hands and knees.

“Rin! I…I’m sorry I didn’t know you were back already, I… I…”

Suna’s intense, narrowed gaze locked onto you and he quickly removed his clothes, his large sheathed cock swelling with excitement as he took his pants off.

Just the sight of him in nothing, with his swollen, leaking cock pointing towards you was enough to make you let out a little whimper of need and you sank down submissively and turned away from him then pressed your face and chest to the floor, holding your hips and ass up to him and praying that he would just hurry up and fuck you so you could have a moment of relief from this dizzying heat spell.

Suna knew what to do and immediately you were stripped of your clothes, your wet boxers being thrown out of the nest before he used his fingers to wipe your lubrication up and spread it over the end of his cock, the soft pink tip gently poking through the foreskin the more he rubbed it with your slick.

“Please?” you whined, your face flushed pink with need as your own cock pulsated with each swipe of his fingers over your hole. 

Silently Suna pushed his giant cock into your ass, holding his body up and over your ass as he arched his hips back and forth, his balls slapping yours with each exuberant thrust deep inside you.

You moaned and cried, keeping your face down on the pillowed-down ground as your alpha groaned and moaned while he ploughing into you.

“Please breed me,” you whispered needily, ” I want to have your offspring, I want to look after our little ones, I want to be able to greet you home each evening with a little one in my arms.”

Suna pressed his weight into you from behind, reaching around and stroking your semi rigid dick before pulling your legs back and leaning into you so that you were laying flat down on your stomach in the middle of your nest. 

You spread your legs more, feeling very full as Suna continued to rail into your ass and making you sweat even more.

His breathing behind you became more urgent and heavy and you could feel the heat from his torso radiating from him across your ass and back.

“Rin~,” you moaned, saliva dribbling from the side of your mouth as your ahegao face remained on full display. 

You could feel Rin’s cock getting harder and harder inside you as he thrust faster and faster, a sure sign that he was getting closer to climax.

“Please knot, please,” you whined, arching back up at him a bit so that he could get a better angle as he fucked you.

He doubled over you more, his fingertips digging into your hips as he bent right over and groaned in your ear, his lips brushing the outer rim of your ear before he turned his head and tucked it in behind your neck and suddenly bit down HARD.

You cried out with surprise as his sharp canines pierced the back of your neck and he held on for dear life, his hips bucking wildly before he suddenly groaned loudly, his locked jaw clamping down harder on your flesh as his cock swelled and locked into your ass, torrents of cum spilling forth and filling you to the hilt.

Through your heat haze you realized that he had just mated you and you let out a little cry of delight, tears from the pain of his teeth in the back of your neck pricking your eyes.

“Rin,” you whimpered happily, “thank you, thank you so much…”

“Our offspring will be much loved,” Rin said as he unlatched his teeth from your neck and lay down on your back, his cock still buried into your ass.

“I will be the best omega,” you promised with glee, turning your head back to lock lips with him.

You kissed passionately for a while with Suna still inside you, still yet unable to remove himself from your ass but you didn’t mind, it made you feel closer to him. Tired from being bred and relieved at feeling the heat symptoms a little less, you finally fell asleep; with Suna still lying protectively over you.

Once his cock had deflated a little he pulled out, a trickle of cum escaping your ass and running down your leg as you lay fast asleep in your little nest.

“He’ll be a good parent. I’ve been wanting to breed him for a while now so I’m glad he wanted it too,” Suna thought as he quietly pulled himself out of the nest and went to eat, making sure to make a little extra for you to eat as well once you had woken up.

*1 year later*

“Welcome home, Rin,” you said in a cheerful voice, bumping your hip a little to help lift the chubby little baby in your arms up your side a bit.

“Thank you,” Suna said softly as he stepped across the door mat and into the house.

“I’ve made you your favourite dish tonight because I know you’ve had a long day of work, providing for us,” you said as you turned around to walk back to the kitchen with the baby on your hip. 

You smiled down at your chubby little one, giving it a kiss on the top of its head while it smiled back at Suna.

“Little Omu here ate so much today! Must have got that from the alpha of this family,” you said with a little chuckle, leading Suna to the kitchen table to sit down, “sit, sit,” you beckoned before tottering off with baby still on hip to get Suna his dinner.

“I’ll hold Omu,” Suna said gently as he stood back up again and reached out to take his offspring before sitting down again so you could get his dinner.

You happily got his meal together then sat it down in front of him and took Omu back.

“Y/N,” Suna said as he looked up at you with his neutral expression.

“Yes, Rin?” You asked inquiringly.

He stood up again and kissed you on the lips, “thank you,”

“Y-You’re welcome,” you stammered with a blush, cuddling your baby to your side and thinking about how wonderful your life was now with Rin’s baby to complete your little family.
