~Izuku's POV~

"Kacchan I-" I started but didn't get to finish my sentences sentence. Kacchan's scent was wrapping around me and clouding my senses. I closed my eyes tightly and ground my teeth. Kacchan shivered and clutched the fabric of my shirt. My eyes snapped open and I walked over to the bed, and quickly but as gently as possible, dropped Katsuki onto the bed "I want you, so bad" I growled and burried my face into Katsuki's neck, inhaling his addicting scent, releasing a low rumble, feeling it vibrate my chest.

"D-Deku! P-please..." Kacchan keened softly and gasped, I pressed my knee against his ass feeling as slick started to wet his pants, I could literally smell the lust rolling off of him and I instantly knew my eyes looked clouded with lust.

I knew it was just because of Kacchan's heat but that didn't make it any better, no matter how much I reminded myself.

"Fuck, Kacchan...Do you know how good you fucking smell? You're driving me crazy" I groaned lowly, kissing his neck, and nipping over his scent gland hearing him whimper cutely, I wanted to mark him right there and then.  I was trying my best hold back, he could tell and was seemingly getting impatient with my fooling around, I really didn't want to scare Kacchan,  what if I let go and fuck him and then he goes to another school or city, or hell maybe even a new country. But Kacchan was seriously having none of this, but he obviously wanted to say something first.

"D-Deku... Before you t-try anything f-funny...Ngh!" He cried out as what seemed like another heat wave hit, his body curled and his legs instantly spread open, allowing me to properly situate myself comfortably. Quickly taking the opportunity I pressed my hips between Kacchan's creamy soft legs and grinded myself into his groin.

"Fuck! Deku...I n-need to s-say something- damnit... I need to say something f-first!" Kacchan was obviously fighting with himself, he apparently needed to say this before he couldn't think straight anymore.

"What is it?" I asked reluctantly pulling away, trying to control deep need to absolutely rail the sexy little omega in front of me, enough to listen to whatever he had to say right this second.

"F-fuck...no matter h-how much I fuckin beg like a b-bitch, do not put that cock anywhere near my hole..." Kacchan growled his cheeks turning a dark shade of red as he squirmed under me, seemingly loosing himself with each passing second. I took a deep breath and nodded slowly. "I'm n-not having sex with s-someone I don't know..." he finished whimpering adorably,  making this harder than it already was. I nodded again grounding my teeth, I wanted to fuck him more than anything right now, but I knew I couldn't.

"I promise..." I said finally watching as he shivered beneath me, shaking my already loose resolve. Suddenly I felt Kacchan's hips grinding upwards, seemingly looking for some kind of friction between us. I gently pushed my arm under Kacchan's head and pressed my lips against his soft plump ones. He immediately kissed back and wrapped his legs around my hips, stripping me of my choice and ability to pull away if need be.

Feeling his increasingly hot body on mine had a grunt force it's way past my lips, I wanted more of this gorgeous omega, so I pushed my hips down, grinding against Kacchan's ass, feeling him shiver against me in return.

"Fuck, you sound so goddamn heavenly" I groaned out, nipping at his soft pink lip, sucking on the lower lip before finally slipping my tongue into his mouth, poking, prodding, and exploring his mouth, drinking in all his hypnotic moans and relishing in the warm, moist cavern of Kacchan's mouth.

Kacchan gasped and pulled away, he looked to be trying to catch his breath, I on the other hand was bearly phased. I was putting 50-50 blame on Kacchan's heat and my breath-holding training with Gang Orca when I was around twelve. I can hold my breath for up to an hour thanks to that. Swiftly, I pulled off his PE shirt and his tank top underneath all at once, tossing them somewhere.

"Fuck, Kacchan you're acting so slutty right now" I moaned breathily and went right back to give his delicious-looking neck some well-deserved attention

"Ah! Deku... please, m-more!" Kacchan cried out and bucked his hips, my resolve was thinning and the Ultima in me just wanted to ravage him. I growled and cut off his beautiful moans by forcefully pushing him back into the bed with my hip and grinding against him feeling his body shudder from the action.

His body curled adorably, so I continued to suck and nip at his neck, hoping to have left purple marks and little scratches on his untainted neck. Kacchan mewled when one of my canines scraped against his scent gland, probably breaking his skin judging by the way his body twitched a bit. I continued to lap and suck on his neck, slowly moving down to his equally untainted collarbones.

Kacchan suddenly reached down and I felt his hands teasingly wander and tug at my PE shirt.

"Eager are we?" I teased chuckling darkly

"P-please I- fuck! I n-need m-more damnit..." Kacchan seemed to be barely able to form his words properly with the way his body was shuddering and shaking from both his heat waves and my ministrations. I then pulled away, before kneeling between the beautiful blonde omega's separated legs. The visible bulge in his pants caused a low growl to shamelessly escape my lips, impatiently, I took the waistbands of both his boxers and his PE pants, yanking them off as quickly as possible. God knows I've wanted to do this for...forever.

From this I heard a surprised yelp from Kacchan but it quickly turned into a moan as I wrapped my hand around his smaller cock, almost completely engulfing it in one single hand, then stroked it slowly but roughly. Kacchan's body seized up and he gripped tightly into the sheets, his quirk activating a little, as he let out a desperate sounding keen of pleasure. I watched as his eyes fluttered and shut tightly when another wave of heat hit his body, leaving small after-shocks in its wake.

I groaned breathlessly at the sight of Kacchan acting this way. My beautiful omega was trembling as I continued to pump his twitching member and I watched as slick flowed from his hole down his plump ass onto his bedsheets.

Kacchan's hands left the crumpled and singed sheets, then fumbled his way to the front of my PE pants. I didn't even give him time to at least attempt to undo the button before I quickly grabbed his hands and pinned them to the bed above his head.

"Fuck yes!" Kacchan keened bucking up against me, feeling his soft moist body rub against my obvious hard-on. One that wouldn't be going away for a while. "...ahgn! Oh my god!"

"My pants stay on Little Omega" I growled nipping at Kacchan's throat while his whole body convulsed with pleasure from being called omega, a natural response from an omega being called as such by an Ultima. I knew I had to keep my pants on or else it would just end with me losing my last ounce of control and end up fucking this gorgeous needy omega, and I had promised him that I wouldn't.

My hands moved painfully slow as I palmed the head of Kacchan's leaking dick, electing a loud cry and another hypnotizing jerk of his hips. I chuckled at the sight and went back to stroking.

"You have no idea how bad I want to fuck you right now Kacchan" I purred into Kacchan's collarbones, this time no doubt leaving trails of red dots down his chest. Kacchan's wouldn't stop squirming in my hand, so I leaned down and gently pressed my lips against the V between my Omega's perfect hips. I continued to stroke and please my omega,  playing with a bead of pre-cum that escaped his slit.

"I c-can't take it! F-fuck me, please! Pin me down and fuck me like you're little bitch!" Kacchan cried out trying to free his hand but my other hand kept his hands pinned to the bed above his head, fingers clawing at my hand begging to be set free. Renewing my grip on his hands, holding tightly, probably leaving little crescent marks from my fingernails digging into his skin.

I didn't mean to, but if I let him go he'll try to take off my pants and I'd allow it, then the next thing you know he's pregnant. I then slowly relaxed returning to my previous job and kept kissing around Kacchan's, 100% pregnancy-worthy hips, ignoring his desperate pleas for dick. Kacchan then stopped clawing at my hand and opted for trying to get to the sheets instead.

"That's a good Omega" I purred smirking as Kacchan gasped when I let go of his hands and wrapped my lips around his dick. His eyes flashed open and stared down at me as I slowly inched him further and further into my mouth. I could've done it in one go, but I wanted Kacchan to enjoy every minute of this.

"D-Daddy! Hng! Oh god!" Mixes of moans and praise flitted past his lips as I felt him buck up into my mouth cutely, but as cute as it was, I was the one in charge here. I released a low growl as my hands came down and pushed my little omega's hips down onto the bed and holding him still while I sucked and licked his twitching member.

The once quiet room was now filled with Kacchan's steady pants and moans along with the heavenly smell of his sweet pheromones. Kacchan's warm hands came down and tapped my head hard, a warning.

"Fuck...I-I'm gonna..." my omega mewled trembling slightly, I pulled off and smirked at his predicament

"That's alright, cum for your Daddy" I purred, my voice not sounding like my own but rather one thick with lust and desire, which I knew damn well I was drunk on before I wrapped my mouth around Kacchan's tip and swirled my tongue around, tasting the dripping pre-cum and listening to his trills and cries of pleasure paired with the heat waves jolting through Kacchan's body.

"D-Da-ddy!" Kacchan stuttered, bucking his hips up one last time, spilling his seed into my happily waiting mouth. Of course, I received it willingly, even going as far as keeping my mouth hung around his pulsating member, letting my omega ride out his high before I finally pulled back and licked my lips.

Kacchan watched me with hazy, cloudy eyes as I moved up his body with kisses before placing a longer, gentler kiss on his swollen lips. Kacchan moaned softly, using whatever energy he had left to lick and suck my tongue, despite the fact that he can taste his own cum on said tongue, hell I can still taste it, not that I'm complaining.

Our kiss deepened for a moment exploring each other as much as possible with Kacchan in his state, before slowly pulling away. I then rolled off Kacchan's tired body and flopped down beside him on the bed. I closed my eyes and waited for the heat to die down, and eventually Kacchan sat up.

"...Deku?" He called out hesitantly

"Yeah?" I answered opening my eyes and looking in his direction

"First...thank you" he said turning to look at me

"For what?" I asked confused

"For both getting me out of there and not having sex with me" he answered shrugging and I nodded "Secondly...why...did you get me out of there"

"...well, naturally I still would've done it since you're an omega in a vulnerable state but," I began trying to properly find my words "I just feel a deep need to protect you over everyone else"

"Mmh, oh yeah, one more thing, well two actually" he grumbled covering his chest "how did you know I was in heat? No one else seemed to have noticed"

"Heightened senses, remember" I chuckled watching him roll his eyes playfully

"And last thing, can you...can you stay with me?" He asked making me excited

"Of course Kacchan" I said smiling "Now it's time I ask a few questions of my own"

"Shoot" Kacchan shrugged

"Was you're heat supposed to start today?" I asked raising an eyebrow. He shook his head

"No, I basically just got off of it, my heat wasn't due for another few weeks" he muttered, obviously aggravated by today's events.

"Do you know what set it off?" I asked, he hesitated before nodding "Would you mind telling me, I mean, I'll be staying until your heat goes away so to know what set you off may be helpful"

For a while he didn't answer me, but then he got up and crawled onto me, resting his wet ass right on top of my hard-on, he trilled cutely, throwing his head back. When comfortable, he looked me right in the eyes

"You" He purred lustfully
