ShinDeku - Izuku's Soulmate

7

It wasn't even a month and Shinsou was hooked. He didn't know what strange magic Izuku had used but one minute he was brooding and the next the hero had him completely wrapped around his finger. Shinsou honestly couldn't say when it happened exactly but after continuously hanging out with him one day he just didn't want to go home so soon.

That day, once they reached the place they usually parted, Shinsou said it."I don't want you to leave."

Izuku had looked at him with such wide eyes and the bright smile he gave him would always stay in his mind. The simplicity of the whole moment was astounding and Shinsou's heart was pounding out of control. He felt the tips of his ears burn and soon the rest of his face was flaming hot. Izuku had outright told him that he was scared of how possessive he would get and yet here they were.

"Do you mean it, Shinsou?" Izuku rushed, grabbing him by the arm and holding tight."Do you really mean what you just said?!"

Shinsou looked away, trying to hide his face."Don't make me say it again..." he mumbled.

And Izuku had kissed him long and hard after that. Shinsou, not knowing what to do with himself, just stood there stiffly like an idiot. When Izuku finally pulled away he had a wistful look on his face and he pulled on Shinsou's arm, having them moving in the direction of his house.

"Well then, let's not waste any time!"

And that led to Shinsou's current situation sprawled out on Izuku's bed, naked, and utterly at a loss for words.

He was glad that Izuku had grown up a bit and didn't paint his room in All Might merch, though he was sure he had a secret stash somewhere. The sheets underneath him were plain enough and comfortable, the pillow he was resting on just the same.

"Don't get distracted, Shinsou," Izuku murmured, leaning forward to kiss his forehead and run his hands through his hair."I'm going to stick another finger in."

"Okay..." Shinsou breathed, back arching slightly as Izuku slid another finger inside his slick hole. He pumped them up and down, spreading them and making Shinsou shudder at the foreign feeling.

He clutched the sheets below him and Izuku moved down to suck on his neck on the opposite side of where his soul mark lied. Shinsou jolted, letting out a small moan at the feeling. He felt warm all over and his soul mark throbbed pleasantly as Izuku lightly bit against his neck in a way that took his breath away.

Izuku nipped against his neck further and then pulled back, Shinsou grunting at the loss of contact. Pulling his fingers out, Izuku rolled a condom over his throbbing member. Shinsou watched the whole process with a heavy breath, anticipation tingling throughout him.

Izuku looked up at him, lustful look in his eyes."Ready?" he asked and Shinsou could only open and close his mouth like a gaping fish as Izuku lined himself over his puckered hole."I'm entering..."

Shinsou let out a loud grunt as Izuku fully slid inside him. He was so warm and felt like he had filled him up just right. He could only sigh around him, arching upward to wrap his arms around Izuku's neck and adjust himself.

"Ah, you're so hot, Shinsou," Izuku breathed."And you're clenching around me perfectly."

Shinsou's breath hitched as Izuku slowly slid out and he could breathe more easily. Then Izuku's hips snapped forward the sudden spike of pain and pleasure knocked Shinsou's breath away, back arching as he suddenly saw stars.

Izuku didn't let up after that, pumping hotly into Shinsou with fervor. He could barely keep up as the intense pleasure sent him over edge, his member dripping with pre-come as he clutched onto Izuku like his life depended on it.

"I knew you'd feel amazing," Izuku moaned, sloppily kissing Shinsou."I love you so much, Shinsou."

He grasp Shinsou's member, pumping it in pace with him and Shinsou was sent over edge at the stimulation. Fresh tears gushed out of his eyes as he moaned heatedly, feeling an intense pressure build up the more he was jerked off. It was all too much and Shinsou felt his vision wavering as his climax started approaching.

"I-Izuku..." he breathed, groaned as Izuku moved down and bit his collarbone."I-I'm..."

Izuku looked up and stopped pumping Shinsou's member, instead grasping it's base and preventing him from coming."Not yet," he whispered."Let's come together..."

Shinsou shivered at the sound of Izuku's low, raspy voice."Sh...Shit..." he moaned, feeling his climax slowly leave him, just out of reach. He attempted to pull Izuku's hand away but he just couldn't find the strength as Izuku kept pumping in and out of him. His shaking hands grasp Izuku's wrist and couldn't go any farther.

"You're so cute, Shinsou," Izuku murmured, Shinsou's body heating up. He took his wrist, pulling himself over his head and leaving them there. His pace slowed as he leaned back to look at Shinsou in such an intense way he suddenly felt madly embarrassed.

"You know, I've done lots of research on soul marks," Izuku started."And the most intriguing thing I've found is that some soul marks can expand and change the closer the pairs are." He pulled his hand off Shinsou's member, slowly running it up his chest and Shinsou watched it, eyes slowly widening at what he saw."It look's like we have those types of soul marks."

Vines, leafs, and flowers all blue spread across Shinsou's chest and arms, starting from it's original spot on his neck and moving down. It was the exact same for Izuku and just seeing it made Shinsou gasp in wonder."W-What..." was all he could utter, completely entranced.

Izuku leaned down, licking a trail up one of the vines and causing Shinsou's breath to hitch at the feeling. He reached the base of his neck, turning his head and biting straight into Shinsou's adams apple. He shivered at the feeling, letting out a small moan at the prickles it left along his skin.

Izuku then snapped his hips and upped the pace again, breathing heavily as he let go of Shinsou's wrist and opted to pumping his throbbing member again. His other arm pulled Shinsou's hips up so he could reach him at a different angle which made Shinsou gasp and grasp at the sheets under him.

The pleasure of the two acts was too much, it was driving Shinsou made. All he could do was moan lewdly, eyes rolling back as his body twitched and shuddered and the intense feeling. He felt so warm and full, it was amazing.

"Mine. Mine," Izuku began chanting, leaning forward and pulling Shinsou into a bruising kiss."Shit...Shinsou..."

Name on his lips, Shinsou's back arched and he grasp at Izuku, whole body shuddering as he finally reached his climax. Izuku followed shortly after, coming hard inside Shinsou with a deep moan.

The two rested like that for a few seconds, simply staring at each other as their breaths slowly evened out. Shinsou leaned up and kissed Izuku, who slowly ran a hand through Shinsou's hair and deepened it.

They pulled back slowly and Izuku rested his head on Shinsou's shoulder."Mine..." he murmured."You're all mine, Shinsou. Please...please don't go anywhere. Don't leave me..."

Shinsou breathed out a small chuckle."I don't think I could even if I wanted to in my current state." He ran a hand through Izuku's sweat slicked hair."I wont leave. You deserve love, Izuku, so please take all of mine."

Izuku smiled, fresh tears in his eyes that he couldn't stop."I will," he hiccuped."Thank you."

A/N: I never really felt like the story was complete after the first book but now I finally feel that it is. Thanks to everyone who waited while I wracked my brain for what the hell I wanted to do for the second story. Your love is appreciated and I hope you enjoyed!
