Kirishima Eijirou

Kirishima was in bed like any other night, although this night was a bit different. The guy he had been crushing on for months was in his bed next to him. They both had spent the night watching movies and causally flirting, which was driving the alpha nuts.

Kaminari had a special way of getting under his skin and making him smile. Kirishima had been afraid to make any real move towards Kaminari because of one reason, and one reason alone. Kami was too important to him and he did not want to get attached and then find out that he wasn't his mate.

Although, it is hard to deny the pull they have towards each other.

It happens more than not that fated mates have dated before because of the intense attraction and connection there, he hopes it is true this time.

Tomorrow is Kirishima's 18th birthday, he can't rip his eyes off the clock on the wall. Counting down the minutes until midnight, his nerves are all over the place as his sleeping crush is wrapped around his body. Kaminari's soft locks of hair are splayed around on his shoulders and his cheek pressed firmly on Kiri's shirtless chest.

He can't help but smile at the peaceful boy and run his fingers through his hair softly as he says a silent prayer to the moon goddess, a plea for this man to be his mate.

Looking at the clock, it's 10 minutes until midnight. Kiri closes his eyes and takes a deep breath, inhaling the sweet scent that flows from the boy in his arms.

Previously, Kami had been flirting with him and lightly touching his leg when Kirishima would tell a joke. While watching movies they had ended in a heated makeout session.

He had been taken by surprise when Kami suddenly got a serious look on his face and his golden-green eyes staring straight at him before flicking to his lips and suddenly crushing their mouths together.

Kirishima lightly touches his lips and smiles, remembering the intense moment. He had been so tempted to take him right then and there but refrains from anything other than some heavy petting that happened.

Kami's hands were shaky and warm as they ran over his body and dipped into the front of his shorts that night, it was enough to drive low growls from his lips. He had been wanting to hold off from any of that stuff for both of their sake, but Kami had seemed to want him, and Kiri wanted him as well.

So, they left it at petting and making out before crashing after Kirishima had given Kami a mind-blowing orgasm just from touching him.

Looking at the clock again Kiri tenses up as he counts down the seconds. One minutes until midnight and it's his birthday.

Kiri's eyes land on the sleeping boy next to him and he wants to wake him up but also want's the chance to escape if his dreams are crushed. 30 seconds left.

Kami shifts in his sleep and nuzzles his face against Kirishima's chest, and the red-headed boy runs his hands over the soft panes of his back as he watches the clock tick by, second by second.

12:00am

Kiri's eyes are closed, and he is holding his breath, he knows the next thing he smells and sees will determine his fate. When he can't stand it any longer, he opens his eyes and takes a staggering breath only to be hit with the most intense wave of pleasurable pheromones he had ever smelt before.

Kami's whole body seemed to radiate a soft light and the hairs on his neck stood up sending shivers through his body. Kami was his fated mate, although Kami is not 18 yet, Kiri can still feel it and know it to be true. His eyes prick with tears and he flings his arms around Kaminari's sleeping body, crushing their bodies together and waking Kami up in the process.

"Kiri?" Kaminari's scratchy voice rang like bells in his ears.

"Mate..." Kirishima growled lowly and pressed his lips hungrily on Kami's mouth, earning a gasp or surprise from the half-awake boy, "You are my fated mate. Mine." Kiri hummed as he felt the overwhelming urge to mark and mate his newfound mate.

There was a gasp of shock from the sparky boy in his arms before he felt a huge smile pull at his lips, making Kiri pull back and look at his mate's face.

"Thank god..." Kaminari sighed breathlessly and reached his pale hand up and ran it softly against Kiri's face.

Kirishima rolled their bodies, pinning Kami underneath him and hitching his hand under Kaminari's left leg and pulling up and around his waist, leaving Kiri slotted nicely between his legs. Even in the dimly lit room, Kirishima could see the blush that fell on his beautiful mate's face.

"Thank god indeed." Kiri hummed and slotted his mouth back in place against Kami's wet lips. The kiss was full of need and desire to be as close as they could be together.

Kirishima felt his self-control slipping away with every passing second, the need to be one with his mate becoming blinding.

"Kami..." Kiri groaned and rolled his hips, grinding into Kami's clothed lower half. His mate whimpered and lifted his hips, trying for more friction.

"I know Kiri, I'm ready. I have liked you for a long time, I wanted to be your mate for months. Mark me, please?"

Kami whispered breathlessly as his fingers dug into Kirishima's broad shoulders and causing the alpha to groan and press his lips to the boy's neck, kissing and sucking along the sensitive skin.

"As you wish, babe."

Kiri grinned and nipped at his neck and making Kami wiggle under him. It was a quick movement that made Kami gasp and moan loudly in a matter of seconds. Kiri had yanked his mate's boxers down and smiled sweetly down at his flusters face.

"Is this the first time someone has touched you here?" Kiri said softly as his fingers brushed his hole and making Kami tense up.

"Y-yes..." Kami whimpered and Kiri pressed his lips to his forehead and hummed.

"Relax, I won't hurt you. Do you want to continue?" Kiri asked and looked down at his mate, he would never force anything on him. If Kami said to stop, he would stop with no questions asked. Kami wigged as Kiri's finger teased lightly against his entrance, Kami didn't stop him.

"I want you, mate." Kami whispered and Kiri smiled down at him and nodded slowly before kissing him again.

This kiss was deep and slow, it poured out love and tenderness. Kirishima did not want to rush this moment and would never rush such a perfect moment with his mate.

Tonight, he would be mating and marking the love of his life, this was not something he could rush. Kiri pulled back and removed his teasing hand before lifting his fingers to Kami's lips.

"Open." Kiri softly ordered and Kami complied instantly, his cheeks heating up as Kiri pressed his two fingers into Kami's mouth.

"Suck." Kiri groaned at the hot and wet cave that sucked on his fingers, coaxing more low sounds from the alpha's body. When his fingers were coated and wet, he pulled away and pressed his index finger to his mate's tight hole, massaging for a moment before gently slipping his finger into the wriggling boy underneath him.

Kami moaned and tensed up, a shocked gasp slipped from his mouth at the foreign feeling.

"Sh, relax love." Kiri cooed at his mate and kissed his lips softly, distracting him from the temporary discomfort.

Kami's body relaxed under his kiss and Kiri began to slowly push his finger deeper, in and out, until his body was accepting the single digit.

"Gah!" Kami moaned when Kiri began pushing his second finger in.

Kami was not an omega, his body could not and would never produce slick like omega's do during their heat to make this an easier process and Kiri knew this.

He would take all the time in the world to prepare his mate for his length. Kami's hands ran down Kirishima's chest until they dove into his boxers and gripped his prick in both hands, giving a long stroke.

"Fuck... Kami..." Kiri groaned and pushed his fingers in knuckle deep into his mate's tight hole.

Kami whined and bucked his hips up as Kiri scissors his fingers, stretching him slowly and searching for a spot that would drive him wild. Kami moaned and whimpered, he was a loud one, Kirishima noticed.

Kiri searched around with his fingers making Kami tense up and wince as his fingers stretched him and probed.

"Hold on, baby. It will feel really good soon." Kiri kissed his neck and groaned as Kami's hands kept rubbing his member and panting.

Suddenly, Kami gasped loudly and arched his back off the matress, cute little huffs of pleasure sounding in the air.

"Fuck!" Kami shouted and moaned, making Kiri chuckle and curl his fingers against his prostate again.

"Found it." Kiri smirked and Kami writhed.

"P-please... Do that a-again!" Kami whined, his body sizzling with pleasure and desire for his mate to be inside him, to claim him.

Kiri pumped his fingers a few more times before pulling them out and wiping his fingers on the sheets. He gripped Kami's thighs and knocked his legs open widen before gripping his mate's member and giving it a few strokes.

"You ready?" Kiri asked softly, wanting to make sure he really wanted this. Kami cracked an eye open and looked at him, nodding.

Kirishima smiled lovingly down at his flustered mate as he tugged his cock slowly and waited for his verbal consent.

"I'm sure." Kami rolled his lip between his teeth slowly and watched as Kiri spit in his hand and rubbed his length and lined himself up, gripping his hard-on and pressing the tip to his entrance.

"Breath." Kiri encouraged softly before slowly pushing inside.

His body was hot and tight squeezing around him almost painfully.

"Shit, babe relax, you're squeezing me."

Kami whined and Kiri rubbed his thighs softly in a relaxing manner, after a few deep breaths Kiri could feel his tight walls relaxing and letting him push in farther before withdrawing and pushing in farther.

Kiri stopped when he was buried to the hilt into Kami's body. Kami was panting with a soft sheen of sweat on his chest and forehead.

He slotted his mouth against Kami's lips and kissed him deeply, slipping his tongue past his lips and exploring his mouth, offering comfort and a distraction.

His mate moaned and wigged, feeling the way his body was reacting to being filled by his alpha.

"Okay, you can move." Kami said breathlessly as he pulled away from the kiss.

Kirishima instantly took the offer and began to slowly thrust as he watched Kaminari's face morph from slight discomfort, into pleasure.

The sight of his face twisted, and his little nose scrunched in pleasure had Kirishima moaning.

"Shit.... K-Kami..." Kirishima moaned and grabbed his knees, pushing them up to his chest and picking up the pace of his thrusting. "You're so fucking tight." Kiri growled lowly and Kami keened at his words. Kami gasped and his eyes flew open, Kiri smirked.

"There we are." Kiri teased and trusted again, making sure to hit that same spot that had his mate crying out in pleasure. Kiri let go of one leg and wrapped his hand around Kami's prick, giving it the attention, he craved.

Kami's back arched and he moaned. His fucked out mate grabbed at the alpha's sides and cried.

"I'm gonna... I... c-cumming!" Kami gasped as he spilled himself into Kirishima's hand, his body writing.

Kiri grunted as his walls tensed and twitched around his length as his thrusts became rougher and sloppy as his mate rode out his orgasm.

"Shit baby, me too." Kiri gasped as Kami panted and was riding his high.

"Fuck, what do you want me to do?" Kiri grunted and leaned down, kissing his mate and moving his lips to Kami's pale neck, sucking on the spot where he would mark him.

"In-Inside." Kami moaned and tensed his body, sending the alpha over the edge.

Kirishima moaned and sunk his teeth into his mate's neck as he emptied himself inside the quivering body beneath him. Kami cried out and hit yet another orgasm, shooting his seed between their bodies on his chest.

Kiri moaned with his canines still latched into Kami's neck before gently pulling out and rolling onto his back, pulling Kami to his side and licking at his mate's neck, closing the wound and then pressing a kiss to his mouth.

"I love you, Denki." Kiri sighed and ran his fingers through his mate's hair, petting him softly.

"I love you too, Eiji," Kami smiled, and Kiri pulled the blankets over their bodies and kept running his fingers through Kami's hair and murmuring sweet nothings in his ear.

"Sleep now, love." Kiri hummed and held his mate tightly, both boys finally feeling complete and fully satisfied with this new life together.
