A/N: Next chapter is up. Thank you again to everyone who left comments, I enjoyed reading them as always. So, fair warning this chapter contains smut. If that isn't your thing you should keep moving, if not, enjoy! This was my first attempt at writing a sexual scene in a while, so I apologize if it's a little rough. I am always happy to accept constructive criticism though!

0FantasyismyReality0: I pretty much had to write down who ended up in which group, so I don't confuse myself. I'm very interested to know what your group names are? Haha

There was something just not right about those wolves, their glowing eyes making an appearance every night for the past 5 nights, slowly creeping closer and closer with each rise of the moon. Shoto wasted no time the morning of the second day. As soon as his quirk returned to him, he immediately erected a wall of ice, its sole purpose to keep the prowling hunters at bay. It was exhausting to keep that wall going, with the constant heat he had to repair it daily, but he just had a feeling if he didn't keep up with it there would be hell to pay.

With significant unease, he counted the pack of feral beasts from his vantage point along the rooftop, binoculars Momo made for him in hand. On that night he was able to count twelve of them, one up from the previous night, pacing back and forth from all sides. He only just relieved Momo of her watch duties a few minutes ago, putting him in charge of their safety for the duration of the night. He shivered, despite the warmth surrounding him and took a sip from his room temperature chocolate. The sweet liquid spilled over his tongue, comforting him as it made its way down to his stomach. He repositioned the binoculars in front of his eyes, studying the wolves' movements with caution.

If he wasn't looking directly at them, he'd never have believed creatures like them could possibly exist. There was nothing "normal" about them. They lurked around on six lithe and muscular legs with each covered in thick white fur. That white fur seemed to stretch along their undersides, also covering their tails and necks. It transitioned to a deep red as the fur grew around their heads and led back down their backs while the fur covering their faces and snouts was grey. He had the displeasure of watching one yawn once and was startled to find its lower mandible split into two, each section lined with serrated teeth meant for tearing and ripping flesh from bone.

Unfortunately, their horrifying teeth weren't even the real problem for the students. The real problem was that they were smart. With each passing night, these animals got closer and closer to his barricade and were now at the point where they were touching it with their noses, as if to inspect it while some were even beginning to scratch at the dirt below. They were growing bolder and Shoto was certain by the next night, they will have breached his ice, effectively forcing them into a conflict without the help of their quirks. That was another problem they uncovered. After enough time, it didn't matter if they were inside the dorms or not, their quirks were still reduced to practically nothing.

If they were all able bodied, they might have stood a chance, but Jiro was injured. She was coherent at least, but with her destroyed leg she would need to rely heavily on their aid to survive. Having reduced quirks and a hindrance on the them like that were bound to lead toward some serious problems. It was a good thing he and Momo were excellent tacticians because they were going to need a foolproof plan and the mercy of the creator himself to survive what was coming for them.

Morning came all too quickly, the rapid temperature increase of the forest forcing Izuku to wake soaked in sweat. The mornings always made him feel a little sick at first, the humidity laying heavy in his lungs while the heat itself coiled around his limbs and felt as though it radiated from his very bones. The environment worked against him in earnest it seemed, zapping him of all his energy and will to move before he could even open his eyes.

Rhythmic breaths caused his upper body to rise and fall with each inhale and exhale from the slumbering body behind him. Izuku tilted his head back, his green curls tickling at Kacchan's chin, to get a look at the sleeping blond. The larger teen slept against the trunk of a tree with Izuku neatly nestled right against him. His toned arms circled around Izuku's waist, hands lazily resting atop the greenette's sturdy thighs. The rope Izuku brought along looped tightly around their waists to ensure neither would fall out of the tree while asleep, leading the teen to feel grateful he remembered to bring it as they tied it around them each night.

Slight shifting followed by a rumbling groan against Izuku's back told him the blond was finally awake. Kacchan was always more of a morning person but even he had difficultly waking up in the sweltering heat.

"Morning Nerd" Katsuki grumbled as he blinked rapidly in an attempt to get his eyes to work. An audible gurgling sound greeted him instead of Deku, leading him to roll his eyes with a laugh. "You hungry, huh?"

"Don't say it Kacchan." Izuku covered his ears with his hands while another loud gurgle sounded around them.

"Oh, I'm going to fucking say it." Katsuki's body shook with barely suppressed laughter as he pulled Izuku's hands from around his ears. "You did it to yourself, Deku. You should have listened to me and not given all of our food to those fuzzy assholes."

"Yes, yes, Kacchan is always right. Got it." Izuku snapped while freeing his hands to take hold of the knot resting against him. He tugged at it with his fingers until it loosened enough for him to untie it. Once untied, Izuku gathered the rope, looping it tightly until it was in a uniform shape and grabbed his backpack to stuff it back in with his other remaining survival gear. He unzipped his bag, but before he could toss it in, an unexpected patch of fur caught his eye.

"Ha! Looks like we have the world's cutest little stow away." Izuku excitedly tapped at Katsuki's knee to get his attention. "Look Kacchan! He wants to come with us!"

"Heh?" Katsuki leaned around Izuku's smaller frame to get a look at what the overly enthusiastic greenette was talking about. "Is that one of the Kawaii? What the hell is it doing in there?" The blond could already tell it was going to be an issue, the fat little fucker would be tedious to keep fed on top of their own needs.

"Maybe after the kyōfu attack last night he figured he'd be safer with us." Izuku reached into his bag to grab the Kawaii, instantly bringing the little animal up to his face so he could rub his cheek against his soft fur.

"Deku, it's a goddamn animal. Stop giving it human characteristics. The glutton probably thought you had more food in your bag and then got stuck… Because that's all it fucking cares about." At this point it was clear Izuku was ignoring his protests and they would be taking the stupidly cute little shit with them. With a heavy sigh, Katsuki jumped from their branch while aiming his palms to the ground so he could use his blasts to soften his landing.

Once on the ground, he looked up to where Deku was still perched in the tree, expecting their new companion to have scampered off in alarm from the noise but of fucking course, the Kawaii was completely unfazed. "Deku, we've got to get moving or we'll never catch up to the others. Pack your shit and let's go."

"Right!" Izuku placed the Kawaii on his shoulder, finished repacking his bag and with the help of one for all, jumped off the branch to join Kacchan on the ground. "So, I think we should give him a name since he'll be coming with us. I like Fluff Might."

"Pft, we are not condemning the poor bastard with an awful name like that. His name will be Lord Carnage."

"You can't be serious? He's too cute to call him Lord Carnage. Come on Kacchan, Fluff Might is perfect for the little guy." Izuku thought about the best way to decide what his name should be as the duo began their trek onward. "I know" he said as he turned to Katsuki. "I'll put him on the ground and we'll both call him using the name we want. He gets the name he answers to."

"That's stupid, Deku. We're not leaving it up to him to decide."

"What's wrong, Kacchan? You worried he'll come to me instead of you?" Izuku knew there was no way the blond would back down from his challenge.

"Tch, I'm not worried about a damn thing. I know he'll come to me." Katsuki stomped over a few feet from Izuku and pointed to the middle ground between them. "Put the little shit down and let's do this."

Izuku walked the Kawaii to the center and gingerly placed him on top of a few fallen leaves before backing up to where he had stood previously. He crouched down so he was more on level with the furball and called to him using a high-pitched tone. "Fluff Might! Come here, Fluff Might!"

Irritated with how Deku started calling him before they agreed to start, Katsuki also knelt and called to the Kawaii in a loud, angry voice. "Get your fat ass over here, Lord Carnage! Come on, Lord Carnage! Get over here or I'll put you on a fucking diet!"

"Kacchan! Don't yell at Fluff Might!" Izuku reached his hand out to beckon the animal over to him. "Come here Fluff Might! You can do it, come on!"

"Threats get things done, damn nerd." Katsuki leveled the Kawaii with a searing glare. "Come on, Lord Carnage, I don't have all fucking day."

"Fluff Might!"

"Lord Carnage!"

Finally, after both boys called to the Kawaii, the furry creature made his choice and slowly inched toward Katsuki.

"What? No! Fluff Might, come back this way!"

The Kawaii ignored Izuku as he continued to make his way over to the blond instead, until he was chittering happily in Katsuki's lap.

"Haha! Lord Carnage it is!" Katsuki stroked his back, a smug smile plastered over his face. "Maybe this little shit won't be so bad after all."

Annoyed, Izuku stood and crossed his arms with a huff. Katsuki had to laugh at how cute Deku looked with his pouting freckled face. He looked so kissable with his lips pushed out like that but Katsuki knew the nerd would probably deck him if he tried. As much as he'd enjoy a tussle, they already wasted enough time on this and really needed to keep going. "C'mon Deku. You lost so quit sulking and let's go." Katsuki turned and continued on the path he believed their classmates had taken; Lord Carnage happily perched on his shoulder as he led the way. He started off slow, like a mother trying to encourage her errant child to follow her after a tantrum, and eventually picked up his pace as soon as he heard Izuku's telltale mutterings coming from just behind him.

They traveled for several hours before Katsuki's ears perked to what sounded like running water, and a lot of it at that. As they grew closer to the source, he could not only hear it but was able to smell it, the smell of fresh flowing water intermingling with the leafy scent of the jungle. Lord Carnage must have noticed too because he was now chittering wildly while impatiently pacing back and forth between his shoulders on all fours.

"You hear that, Kacchan? We haven't seen any running water for days now! I think the last time was when Jiro- Actually, you know, I wonder how she's doing? I wish there was a way for us to contact them and check in on her. Shoto and Yaoyorozu are capable though. Tsu too. I'm sure they're fine. Anyway, maybe if we are careful about the smell of those crocodile things we could go for a swim? I don't know about you but I'm pretty sure I stink." He paused, a small frown forming on his face as he considered his recent proximity to the blond. "Kacchan? Do you think I stink? Is it bad? I mean, I didn't notice any strong odor from you but maybe that's because we both stink…"

"You smell like a Deku" Kacchan responded, secretly smiling because he kind of liked the smell of a Deku apparently.

"I don't know how to take that, Kacchan… Oh! You know what? I just realized something that might be amazing. If there's water, there might be fish! We might get to eat fish for dinner!" Izuku continued to ramble about fish, Katsuki only half listening before he decided to interrupt him.

"We don't have time to take a damn bath or catch fish. We should keep going." The distraught look Izuku gave him in response made him almost feel bad for being the responsible one. Almost. Especially because that look almost immediately morphed into rebellion, Izuku's eyes hardening in challenge.

"No, Kacchan. I've been going along with what you want at almost every turn, but I won't let you ruin this for me. I want to bathe, and I want to eat some fish. You are going to bathe too, and you are going to cook the fish and… and… you're going to like it!" Izuku stomped his foot on the ground in a show of his defiance. He could be such a little brat sometimes.

"The fuck you just say to me? I don't have to like anything and your damn right I will cook the fish because if I let you do it, you'll char it beyond recognition."

"I can too cook, I just- wait, did you just agree to something I want?" Izuku gave him a sideways look, not really sure how to take that unexpected development.

"No, I decided we would be more fit to continue forward if we were clean and better fed. Got a fucking problem with that?"

"Nope!" Izuku looked giddy as he ran up to Katsuki, kissed him on the cheek and skipped ahead toward the sound of the water.

"Tch, damn nerd" Katsuki grumbled as he pet the soft fur of Lord Carnage who seemed to be inspecting the inside of his ear with interest. "Knock it the fuck off" he scolded while trying to suppress a smile at the furry fuck's antics.

They didn't have to walk much further before that sound of rushing water transformed into the thunderous roar of an enormous waterfall. Thousands of gallons splashed down the side of a cliff, the foaming water accumulating in a deep, circular pool at the bottom. The pool of water then had two outlets, one carving a path to the east and another to the south. The pool itself seemed to cast off a greenish hue with white rapids and as Izuku inched closer to the end of the moss-covered bank he even saw a single grey fish darting through the water.

Algae grew in thick clumps along the rocks of the cliff where the water continually rushed down, whereas the rest of the cliff and pool of water were framed by the lush greenery of the jungle. The tree line above them had split open to reveal a beautiful blue sky and the bright orange rays of the sun. This was the first time either of them felt direct sunlight against their skin in almost a week, with both eagerly welcoming the warm rays.

Lord Carnage scampered down Katsuki's form, making his way to the water line where he began his diligent search for bugs. He turned over rocks, sifted through pebbles, and investigated the patches of grass growing around the edge of the bank.

Izuku watched him for a moment before taking off his backpack and pulling his damp shirt over his head, tossing it haphazardly behind him. His pale skin was practically fluorescent beneath the beating rays of the sun, his freckles lighting up as if they were dozens of little stars littered all over his well-built body. He knelt to untie his shoes and when they were both off, he looked up to Katsuki, mischief gleaming in those emerald eyes.

"Last person to catch a fish has to clean any fish we catch today" He yelled behind him, already running toward the water.

"Shitty Deku! You can't just call that when I haven't even taken my shirt off!" Katsuki threw both shoes and his shirt in different directions before barreling in after Izuku. The water splashed around him as he ran through it, when he suddenly dropped down into deeper water. He wasn't expecting it to drop off like that and he gasped in surprise before his head was fully submerged beneath the surface.

He'd be lying if he said the warm water didn't feel damn good against his skin. He could practically feel the dirt and sweat as it lifted from his pores and was carried away by the cleansing tide. He opened his eyes so he could look around, the water surprisingly clear as he inspected his surroundings. The muffled water sounds were a nice change compared to the loud and animated noises of the jungle he was constantly subjected to and at that moment he wanted nothing more than to relax within the calming embrace of tranquility.

A flash of green, Deku's one for all most likely, pulled him from his moment of peace, reminding him he had some serious ass to kick. If Deku was using one for all he would catch a fish in no time. Katsuki would need to use his own quirk too but the question remained, what would be the best method to efficiently outdo the brat? He smiled wickedly as he came to a decision.

Swimming quickly, he rose to the surface of the water and made his way back to dry land. He then aimed his palm at the side of the water he didn't think Deku was swimming in, which he assumed given he could still see flashes of green well on the opposite end, and formed his other hand into a circle and placed it in front of his open palm. He focused his explosion and released, shouting "AP Shot Auto Cannon!"

Immediately, the pool of water was bombarded with mini projectile explosions, splashing loudly as each one made impact. At this point two things happened. Deku comically flung himself out of the water, the fear of God flashing in his panicked eyes meanwhile the bodies of several shell-shocked fish floated to the surface.

With his head whipping every which way, eyes darting around like he was high on meth, Izuku searched for the danger. With each second that passed and every ragged breath that escaped his lips, he slowly realized there was nothing there. That's when a smirking Kacchan wading through the water while collecting fish caught his attention.

" . .YOU." He screamed as he watched Kacchan in dismay.

"I'm getting a hell of a lot of fish for you to clean for dinner. What's it look like, stupid Deku?" Kacchan chuckled as he made his way back to land, arms full of colorful, slippery fish.

Izuku wasn't having it though. "You cheated, Kacchan. That's not fair."

"Pretty sure you never specified how the fish were to be caught. And I saw you using OFA so I'm also pretty fucking sure I didn't do anything differently from you." Katsuki raised an eyebrow at Izuku before dropping his catch at Izuku's feet. "I have a knife in my bag that you can use to descale them. Get started while I get a fire going."

At first, Izuku only glared rebelliously at him, feeling hoodwinked by the way Katsuki won their competition. Katsuki glared right back at him, meeting his challenge head on and waited to see what his next move would be. Eventually, Izuku's expression softened some and he looked to the ground as he mumbled, "I um, don't know how."

"I'm completely unsurprised by that news. I'll show you, come here." Katsuki grabbed his knife from his bag and picked up one of the fish. "So, first you want to remove the scales by sliding the dull side of the knife over the scales, like this. Next, you flip your fish over and insert the tip of your knife into its bottom and swipe the blade through the belly in a straight, shallow line until you've reached just under its head." Katsuki performed the task, the knife making a slick squishy sound as it cut through the fish. Izuku visibly paled as he watched the blond work. "Next, you wanna get your fingers in there and work out all of the innards, opening the fish as you go to make sure you get all of that darker stuff that's stuck along the walls out too." As Katsuki finished this part of the process he heard a weird sound coming from above him and paused just in time to watch the damn nerd dry heave like the nerd he was.

Pale as a ghost and wide eyed, Izuku covered his mouth as he tried to hold in the heaving, his body lurching despite his efforts. When his body calmed down, he rubbed the tears that formed in his eyes and nodded his head at Katsuki. "Okay, continue." He grimaced as he fought against the nauseous, determined to see this through.

"Right, I don't really want you puking all over our dinner so why don't you be useful and set up the fire and I'll clean the fish. I'll be over to light it when I'm done."

Though he felt disappointed in his inability to clean the fish, more then anything, Izuku was just relieved to have a different task that didn't involve pulling entrails out of his future dinner. It didn't take long for him to have a fire ready and Kacchan was unbelievable quick, having all the fish prepared and skewered with long sticks by the time Izuku was finished.

They sat side by side as they ate their dinner. Izuku praising Kacchan for his perfectly roasted fish, Katsuki enjoying Izuku's praise of "Kacchan is so amazing" for the first time since they were toddlers. Lord Carnage made his home on top of Izuku's green mop, accepting bites of fish as the greenette offered them to him.

"Whew, I'm stuffed!" Izuku proclaimed as he happily rubbed his full belly. "That really was amazing Kacchan. Guess I should thank the chef?" Izuku giggled as he leaned over and gave Kacchan a chaste kiss, lingering for just a second before moving back.

"Damn straight. Welcome, nerd." Katsuki lounged back, supporting his weight on his palms as he watched the continuous flow of water cascade down the cliffside. Everything about their location was truly beautiful, like a work of art that was too perfect to be real. Still, they've been there for long enough, at least a couple hours at this point, and it was time for them to get going. "Deku, we've been here too long. We should get a move on."

"What? Oh Kacchan, can we take one last dip in the water? It was so refreshing and who knows when we'll be able to do it again. Please?" Izuku gave him his best puppy dog eyes, a look that used to have little effect on Katsuki but now for some damned reason he couldn't seem to say "no." Truthfully, he wouldn't mind taking one last dip himself so really it was like he was agreeing to it because he wanted to. It wasn't like he was getting soft or anything.

"Fine, but not for too long. The idea of those extras getting even further ahead pisses me off."

Izuku bounced up and pumped his fist into the air, cheering as he took his shirt and shoes off once more to run into the water with Katsuki right on his tail. The blond watched with amusement as Izuku swam to and fro before rolling over to float on his back. He looked so relaxed, so happy, that Kacchan felt now was the right time to mess with him. He swam up close to the other teen and set off an explosion in his direction, the force of it spraying water all over Izuku.

Alarmed, he flailed his arms and legs with a yelp before sinking into the water. An angry blob of green popped back out a second later, leveling the blond with a determined stare. Before Katsuki could react, green currents encased Izuku and he rose his hand just above the water and flicked his fingers toward him. Katsuki was immediately smacked in the face by a strong gust of wind followed by a wave of water. He coughed and spluttered as he wiped the water from his face, pretty sure Izuku might have won that round but unwilling to admit it.

"You're dead meat, Deku!" He yelled while swimming toward Izuku, like a shark about to catch its prey.

Izuku saw him coming, having just enough time to wonder if maybe he had gotten too carried away when the blond dunked him under the water, grinning manically while Izuku tried to resurface. Eventually, he was able to free himself and get his head above the water line. He sneezed several times, his nose burning from the feeling of accidently breathing in water. He splashed a normal amount of water toward the blond with his hand, deciding he had in fact gotten too carried away the first time.

"You never learn" Katsuki said ominously as he swam closer to Izuku.

Izuku smiled brightly at him, accepting Katsuki's challenge as he splashed him in the face again. "I guess not, Kacchan." He shrugged and went for a third splash but stopped when Katsuki grabbed his wrist.

On his way over, Katsuki fully intended to dunk the nerd again but now that he was right there, staring into those captivating, emerald eyes he quickly thought of a better plan. He tugged at Izuku's wrist, bringing the smaller teen in closer until their noses were touching. He felt Izuku's warm breath fan out over his face and he could feel his accelerated heart beats thrumming wildly against his chest. He cupped Izuku's cheeks with his calloused hands and pressed their lips together in a searing kiss.

Instantly, he swept his tongue over Izuku's, humming deeply in his chest in appreciation of his decadent taste. As they continued to make out, they both quickly realized they were finding it difficult to breath between locking lips and continuously treading water so Katsuki broke away just long enough to lead Izuku to the shallow area where the water was only a foot or so deep.

Katsuki took a seat and pulled Izuku onto his lap, the teen straddling his hips, his freckled cheeks dusted in the lightest shade of pink. Katsuki ran his fingers through green locks, tugging Izuku's head toward him so they could resume their kiss while his hands trailed down Izuku's bare back, his skin slippery and soft beneath his wandering touch. He slowly continued his decent, only stopping once he was cupping Izuku's firm ass tightly. Sometimes Katsuki forgot how stacked Izuku really was. He'd never guess it from the nerd's coy demeanor and the baggy clothes he insisted on wearing, but between his thick thighs, the rippling muscles stretching down his back and chest, and that perfectly tight ass, Izuku's body was really something worth marveling at.

Izuku in turn ran his fingers down Katsuki's well-built chest and abs, tracing the contours and smooth bumps as he went. A part of Izuku couldn't believe Kacchan was letting him touch him like that but another part was so lost in sensually exploring his partner's body that he wasn't about to question it. Then of course there was the even smaller part of him, pushed to the back of his mind, that was freaking out from embarrassment.

With his hands still firmly gripping at Izuku's ass, Katsuki subtly pulled Izuku against himself, rocking his hips forward, chasing after any kind of friction he could get. Izuku seemed to have appreciated the movement because he whimpered lowly in his mouth, taking over and rocking his own hips and rubbing their hard erections together through their soaking wet clothes.

Breaking away from their kiss, Katsuki instead pressed his lips against Izuku's neck, sucking and biting until a swath of purple bruises formed along his damp skin. Each suck and bite were like electric, shooting tingling waves of pleasure that went straight to Izuku's dick. Izuku tossed his head back and moaned loudly, now grinding his hips down with desperation unlike anything he'd experienced before in his life.

"Mmm, Kacchan's so amazing. Kacchan's incredible, so strong." Izuku mumbled praises, his fingers burying themselves in Katsuki's blond spikes.

Loving every sound Deku was making, Katsuki decided he needed to know what other sounds he could elicit from the teen. He pressed his tongue against Izuku's collar bone, slowly gliding it up to just behind his ear and moving his mouth to nibble on his earlobe. Izuku bucked his hips with a groan, goosebumps forming along his arms and the hair on the back of his neck standing up. It was then that Izuku whispered something so quiet, Katsuki almost missed it.

"I-I need more Kacchan."

Katsuki slowed his assault on Izuku's neck, wanting to make sure he heard him right. "You want more, Deku? Tell me how badly you want more, and I'll give it to you right now."

Izuku pulled away to look him right in the eyes and Katsuki didn't miss the look of desire that lingered beneath that innocent stare. "Please Kacchan." Izuku roughly gyrated his hips against Katsuki, his voice heavy with need. "I'm so hard it hurts. I just… I need more Kacchan!" That blush was coming back full force now, Izuku not used to asking for something so perverse.

More than anything, Katsuki wanted to give in to his staggering desire to take Izuku, to claim his body as his own, but he had to be sure this was what they both wanted. "Izuku" he said in a rare instance of using Izuku's given first name. It had the desired effect, the surprised greenette looking at him curiously now. "If we start this, I… I don't think I could stop. Are you really okay with this?" This line of questioning made Katsuki feel exposed and vulnerable in a way he didn't like. He wasn't sure what he'd do if Izuku denied him.

Biting his lip, Izuku seemed to think about it for a second too long, filling Katsuki with a sense of dread before he finally said "I'm more than okay with this. I want it, Katsuki."

Hearing his own given name escape from the nerd's lips made Katsuki's cock throb within the confines of his pants. He didn't need any more consent than that and crashed their lips back together, their teeth knocking at first as he urgently reached for the button on Izuku's pants. He fumbled with the little metal button before finally freeing it. Izuku raised his hips while Katsuki shimmied the material down his thighs, stopping because he couldn't get them down any further with Izuku's legs spread apart like they were.

Catching on, Izuku stood so he could remove them the rest of the way, not expecting Katsuki to reach up and tuck his fingers under the waistband of his underwear and pull them down with a swift tug. Izuku's whole body heated up the moment he realized he was fully exposed, and he instinctually went to cover himself.

"Don't you fucking dare" Katsuki growled as he removed Izuku's hands.

At first Izuku fought him, trying to cover himself again but the moment he noticed the fiery hunger burning in Katsuki's eyes he stopped. In fact, it felt like time itself had stopped. Never, had anyone looked at Izuku like that before. Katsuki looked at him like he was a full course meal, like he was starving and was about to eat for the first time in days. That look alone made Izuku's mouth water and his cock twitch with anticipation.

Never breaking eye contact, Katsuki wrapped his hand around Izuku's cock, licking his lips as he thought about what he was about to do. Obviously, he had never done anything like this before. In fact, before now he never even really considered entertaining any kind of romantic relationship. He was out to become the number one hero and with a rival like Deku, well, he didn't have time to spare. He especially wouldn't have guessed it would be the nerd who finally caught his attention but now here they were, his attention not only caught but wholly focused on making the nerd scream for him.

Slowly, Katsuki started to pump his hand up and down the length of Izuku's hard member, their soaked state making it easy for his hand to glide over the silky skin and pulsing veins. He stuck his tongue out and licked from the base of his cock all the way to the tip. Izuku's body spasmed from the stimulation, his eyes hazy with want.

"K-Kacchan!" he started, then stopped feeling too embarrassed to continue.

A cocky smile crept over Katsuki's face, knowing exactly what the nerd was asking for. He licked again, loving the way every stroke of his tongue caused Izuku's body to shake. "What do you want me to do next, Zuku?"

"I… I don't know" Izuku stuttered, his increased panting making it difficult to form words.

"I think you do know. I'm not going any further until I hear you say it." Smirking, Katsuki flicked the head of Izuku's dick with his tongue, lapping up the precum he found there and enjoying his slow torturing of the nerd.

His bottom lip was firmly pressed between his teeth as Izuku desperately tried to hold himself together. He couldn't believe he was actually about to say it, but he wanted it enough that he was willing to go through with it no matter how embarrassing. "I want you to s-suck my cock."

"Such a dirty mouth, Deku. What do you think the extras would say if they knew you talked like that?" Before Izuku could respond, Katsuki opened his mouth wide and slid as much of Izuku in as he could manage.

Shuddering, Izuku watched as his cock disappeared inch by inch between those lips. The wet and warm feeling of Katsuki's mouth sent ripples of pleasure coursing through his body, amazed at how much better it like this then when he would take care of himself.

Though his eyes were watering from the foreign feeling of something filling his mouth, Katsuki relaxed his jaw and pushed further until he felt Izuku's head brush against the back of his throat. He was rewarded with a flurry of whimpers and groans as Izuku fisted his hands in his blond hair. With his eyes still focused on Izuku's darkened green irises, Katsuki slid his mouth back toward the head, brushing his tongue along the underside of Izuku's cock as he went.

Transfixed, Izuku watched as his glistening cock was revealed, soaked in saliva and possibly one of the hottest things he'd ever seen. Without lingering too long, Katsuki swallowed him up again, setting an unhurried pace, making sure to pump his hand at the base where he couldn't comfortably reach with his lips.

It didn't take long for Izuku to feel a familiar warmth pool in the pit of his stomach, slowly stretching out to encompass his entire body. His knees felt weak and his toes curled while he gently urged his hips forward in time with Katsuki's mouth.

"Oh god, Kacchan. I- I think I'm gonna, gonna cum!"

Katsuki smirked proudly around Izuku's cock, quickening his pace until he felt Izuku's warm cum shoot out and coat the inside of his mouth. He swallowed every last drop before sliding his mouth off with a pop. "You taste so good" He said as he wiped the excess drool from his lips with the back of his hand, watching with satisfaction as Izuku's cock continued to spasm as the greenette came down from his orgasm.

"That was… that was amazing" Izuku panted, his body still buzzing pleasantly. He watched as Katsuki stood and removed his own pants throwing them behind him to join Izuku's clothing on the bank. He then slid his boxers down, his hard erection springing out and bouncing in all of its glory. He was huge and Izuku swallowed thickly as he imagined being split open by its considerable girth. Excitement and apprehension swirled together in a heady combination as he watched Katsuki sit back down, the water splashing around him.

"Come here, Zuku." Katsuki said as he reached his hand out toward the greenette, his normally prideful eyes showing a glimmer of vulnerability.

Nervous as he was, Izuku accepted his hand and straddled his legs around Katsuki's hips, their cocks pressed against each other between their bodies. Izuku wrapped his hand around both lengths, pumping it up and down, his movements stuttered from how sensitive his own cock still was from his orgasm. He felt as Katsuki reached his hand around his waist, dipped down into the warm water and slid down his backside, continuing until he was tracing small circles around the ring of muscle forming Izuku's entrance. His breath hitched in his throat as Katsuki finally pushed that finger inside him, the sensation pinching and not exactly pleasant.

When Izuku's body stiffened Katsuki noticed immediately and stopped pushing in so Izuku could adjust to the intrusion. "I'm going to go slow, I don't wanna hurt you" he said, trying to comfort Izuku. Once he felt Izuku relax against him he pushed in the rest of the way, sliding his finger in and out and eventually pushing in a second finger. He continued to prep Izuku, stretching him until his walls gave less resistance and Izuku even started grinding his ass down on him, clearly beginning to enjoy the sensation.

"Are you ready to take my cock, Deku?" Katsuki asked as he pulled his fingers out and started to tease Izuku's puckered hole with the head of his throbbing member.

Nodding his head with enthusiasm, though inside he was nervous as hell, Izuku tried to relax his body as he wrapped his arms around Katsuki's neck and pressed their foreheads together. The blond slowly rocked his hips upward, pressing into Izuku carefully until his cock was fully sheathed inside that un-fucking-believably tight warmth.

Izuku cried out when Katsuki entered him, the stinging pain hurt more than he was expecting. He squeezed his eyes shut while squeezing his thighs together with enough force that Katsuki would likely have bruises around his hips the next day. The blond peppered him with kisses while rubbing his back in soothing circles, trying to help him calm down some.

"Try to relax and breath, Izuku" Katsuki whispered as he did his best not to rock his hips, waiting for Izuku to give him the okay first. He noticed the tears that pricked at the corners of Izuku's eyes and he kissed them away while he continued to rub the tense muscles of Izuku's back. Eventually he felt the greenette physically relax into him.

"Okay Kacchan, I'm ready." Izuku started to slowly grind his pelvis down, feeling little flutters of warmth steak through his body as he did. Katsuki started to move too, thrusting up and into Izuku at a slow pace.

"Holy fucking shit, Deku. You feel so good." It was so tight Katsuki could barely move without releasing a powerful wave of pleasure, making him realize that he probably wasn't going to last long. He continued his leisurely pace, both teens shuddering with every movement.

"Kacchan really, I'm okay now. You can… you can go faster." Izuku was impatiently wriggling his ass down on Katsuki's cock, trying to force him in as deep as he could go.

"I'll make you regret those words, nerd" Katsuki challenged, meeting Izuku's downward movements with powerful, deep thrusts until he hit a spot buried inside Izuku that made him scream.

"Ah! God Kacchan, so good. You're so good. Please don't stop!" Izuku was moving completely in sync with Katsuki, their slick bodies rising and falling in rhythm together. The water splashed loudly around them, the sound of their sex releasing wet squelching sounds into the air. Katsuki continued to thrust deeply into Izuku, making sure to hit that spot again and again.

The silken walls wrapped around Katsuki's cock were beginning to coil even tighter with Izuku's impending orgasm. He watched as Izuku's brows furrowed, his puffy lips forming an "O" and his eyes roll back when his orgasm hit him. It was unlike anything Izuku had ever experienced and he arched his back and dug his fingers into Katsuki's shoulders as the pool of warmth deep inside of him exploded, sending wave after wave of heat to crash through his shaking body.

Between Izuku's tight warmth squeezing the life out of his cock and the delicious expressions painted on Izuku's face as he came for him, Katsuki shuddered as he felt is own impending release. "Ah fuck, I'm going to cum!"

"Yes! I want Kacchan's cum inside me. Please Kacchan, I need you to fill me up with your cum!"

Izuku just begged him for his cum and Katsuki would be damned if he didn't give it to him. He saw stars as his orgasm hit him hard. He buried his head in the crook of Izuku's shoulder, continuously thrusting into him until his seed sprayed out and coated Izuku's walls.

It took him a second to catch his breath, but when Katsuki did he lifted his head so he could inspect Izuku, make sure he was okay. He wasn't expecting to see the nerd looking back at him, his expression fully sated but also so full of admiration that it made his heart flutter just a little. "You good, Deku?"

"I'm more then good, Kacchan."
