Bakugo's P.O.V.

Tap. Tap. Tap. Tap. Tap. The sound of my pencil hitting my notebook for only the thousandth time. How the hell am I supposed to do math homework when all I can think about is Deku. My boyfriend Deku. Ugh it still sounds weird! It's all I've been asking for in the past few months, and now that I have it… ugh! It just doesn't hit right. This morning, he hugged me, we had worked through our differences and were headed towards something more, then Icy Hot… it's like he did it to prove a point to him. And that's really pissing me off. I feel used! Sort of… I mean I got what I wanted… yet it doesn't feel right at all. Stupid Deku. Stupid Icy Hot. Ugh! I exploded the pencil in my hand then threw what was left at the wall. This is so wrong! It feels so weird!

Deciding not to sit here and stew and mope, I went through our connecting doors to Kirishima's room. I burst through the door and the room was empty. Great. Just great. He's probably with his boyfriend like always. The two are damn inseparable. Damn it! Fuck! I went back in my room and heard a knock on my door.

"What?" I growled.

"It's me." Deku. I let out a pent-up breath I'd been holding and answered the door, glaring down at him. "Is that any way to look at your boyfriend?" He said with a smile. My glare only deepened. His smile quickly faded. "Can I come in?" He offered.

Rolling my eyes, I opened the door further, letting him in, inspecting him as he walked in. He was freshly showered, but he smelled… like he's been rolling around in a minty meadow, frolicking really. Like an omega about to start his heat. Fuck Deku.

"You're about to start your heat." His eyes widened. Like a scared fuckin dear.

"In a couple of days, yeah."

"You already reek, put some scent blockers on or something." I said covering my nose and laying on my back on my bed.

"You don't like it?" He asked, playing with the hem of his shirt, giving me doe eyes. I fuckin love it, but that's not the point.

"It's… alright." I beckoned him to come over, he did slowly, then laid on my chest. His scent made me want to rut. I haven't had a good rut since this summer with Kirishima, and even then, I'm not sure I got it fully out of my system.

"Are you okay?" He asked knowingly, gripping my shirt lightly.

"You already know I'm not."

He let out a puff of breath. "Should I even ask what's bothering you?"

"As if you don't know."

"This isn't about lunch today is it?"

"What else could it be about Deku?"

"I… I thought this is what you wanted." He said looking up at me, those green eyes giving me a worried look.

"It is but-"

"But what?"

"In front of Icy Hot? Really?"

"I just happened that way Kacchan." He said turning away from me. Oh no you don't.

"Don't you turn away from me." I said pulling him roughly back to my chest.

"You got what you wanted, who cares how we got here?"

"Because it matters Deku!" I nearly screamed.

"Why?" He screamed back. God he's so difficult.

"Because!" I screamed and then stopped, seeing the look on his face. Oh fuck. Why does he make me feel so bad, so guilty? "Because… Because I need to know that you want this too." I muttered, not looking at him.

"It's not clear that I do?"

"No." I said indigently.

He grabbed me by the face, gripping me tightly, forcing me to look him in the eye. "I want this Kacchan. I want you."

"And Half n' half? You're over him?" His eyes looked hurt. It was obvious he wasn't. I knew that. It's not like I think he's gonna go running after him. I just… want him to want me. Is that so bad? Deku swallowed, hesitating. "I want to move on. I want to move on with you. If you'll have me…" Deku was still heartbroken. That I had to accept. And I if wanted him, I'd just have to mend his heart, it's my responsibility after all. Alright… Alright.

"You're mine now Deku." I said, pulling him close, scenting his neck.

"I'm yours." He confirmed, scenting me back. His scent was overwhelming, being in his pre-heat state. It made me salivate, I wanted him, needed him. I found myself sucking on his neck, lapping at the scent gland that was starting to become visible in preheat. His scent dictated my movements, going straight to my dick as I spread his legs across my lap.

"Kacchan." He giggled, putting both hands on my face and kissing me, his lust becoming more palpable by the second. I let out a growl, my hands heading down his back and finding his ass, wanting to rip his pants off right there. Losing control, I did. Deku gasped, slapping his hand against my chest. "Kacchan!"

"What? You think you can keep me waiting for this long and not want you. I'm gonna tear you apart." I said with a deep grow bubbling in my chest, I felt him become soaking wet by my gesture as I teased his hole with my finger. I need to rut. I need Deku. His scent was just way too much and he's finally, finally mine! He licked his lips devilishly, then moved down to undo my pants. We hurriedly slipped them off along with both of our shirts and the rest of our clothing, nearly tearing it off. I reached under him, playing with his hole once more, he was so wet! I gingerly stuck a finger in, this throbbing hole clenched around me. Mmmmm.

"You're nice and tight for me Deku. I'm gonna stretch you out and fill you up so good."

"Mmmm Kacchan, please." I abruptly flipped him over, slamming his back on the bed, my fangs came out, looking down on my delicious prey. All I could think about was claiming him, making him mine. I grabbed his wrist and sunk my teeth in. "Nugh!" Deku writhed in pleasure, arching his back underneath me, releasing more of his beautifully blissful scent. It put me into a frenzy. I began to bite any piece of skin I came into contact with, sucking, licking, sinking my teeth into him as I breached his barrier. Deku and I became completely blissed out, playing off of each other's scents, moving in tandem and with force. Deku was so warm surrounding me, so tight and wet, willing me to go into a powerful rut. I fucked him hard and strong. His legs wrapping around me, his fingernails gripping into my back to steady himself.

"God I wanna breed you." I felt the alpha within me say. "Make you fat with my pups."

"Mmmmm Kacchan!" He purred, arching away from me to run away from the pleasure.

"Nuh… I wanna mark you, claim you, make you mine forever." I said forcing him to feel the pleasure I was giving him, marking up his collar bone, holding him firmly in my grasp.

"I want your knot Kacchan."

"You gonna be my dirty slut for it? Take it any time, whenever, wherever I want to give it to you."

"Only yours."

"Only mine." I growled deeper into his scent gland, his words quickly filling my knot. Fuck. Fuck. "Oh Deku."

"Kacchan." I reached down and took his dick in my hand, stroking him to give him one final push over the edge. He came with a voiceless scream, his eyes widening as he came with a powerful force, his scent filling all of my senses. I couldn't take it anymore. I was absolutely feral. Claim him, mark him Katsuki! I released my knot inside of him, and in that moment lost all control. My fangs were on the scent gland in his neck, digging in, drawing blood. Mark him Katsuki, harder! "Kacchan!" As I sunk my teeth in deeper, reaching my highest peak, ready to claim, I was hit with a Detroit Smash right in the god damn jaw.

Midoriya's P.O.V.

"So… did you get it?"

"Yeah, Yayaorozu brought it to me this morning."

"Well, what does it look like?" I let my fingers trail along the well-crafted collar on my bed.

"It's dark green, the material is strong, but flexible. Impenetrable by fangs certainly. It won't be noticeable under my hero costume. Umm… the lock is nice, complex."

"And it's a full collar?"

I nodded although it seemed silly as my mother couldn't see me through the phone. "It is. It will cover my full neck, most of my shoulders and collarbone."

"Oh Izuku." He voice sounded so sad. "Are you sure this is what you want?"

I'm too young to be claimed, I don't want to be claimed before I'm a hero. It's just not time. "Yes mom, this is my decision and I'm sticking to it."

"You know the stigma of omegas that wear collars." They're either prudish, betrothed, or being controlled by their mates. At least that's the thought. Either way alphas aren't fond of collars. They want to see our necks, smell our scent glands. I just… I don't need to tempt Kacchan like that. He can't handle it.

"Discrimination is illegal." I replied. Although now it's like I'm wearing a bright red sign that says I'm an Omega. "I just want to be safe mom. You want that for me, don't you?" I added.

"Yes Izuku, you know that I do. I just… never thought it would come to you wearing a collar."

"I know mom… I should get ready for school."

"Please let me know how your day goes."

"I will. I love you."

"I love you too sweetheart." I hung up the phone and as I did there was a knock on my door. I opened it up to see my boyfriend with a two-day old bruise I made on his jaw, it made me feel incredibly guilty.

"She bring it?"

"Yeah, she just dropped it off." I said, inviting him in. He went over to the bed and picked it up.

"You don't have to do this." My hand went to my neck, feeling the thread keeping my flesh together in my fingertips.

"The fifteen stiches in my neck would say otherwise." I muttered, looking away. His fangs nearly tore through my jugular. Any deeper, a second longer, they would have.

"You didn't have to Detroit Smash me into the damn wall." It was a Texas smash actually. Slightly more powerful, but I doubt he'd want to hear that now. Especially since I broke his jaw and Recovery Girl had to reset it…

"I don't think saying 'Kacchan stop' would have been quite as effective."

"You don't have to wear a damn collar around me."

"It's just better this way." I'm not ready to be claimed just yet. I went to my dresser and took out a long-sleeved dry fit turtleneck. I took my t-shirt off and began to put the turtleneck on. Kacchan stopped me, running his hands along the marks he left on my chest and arms. I had so many bites. So many marks and hickeys.

"You don't have to hide them." He pleaded. I looked up to the mirror. Part of me loved seeing the marks Kacchan left on my body, the other part of me didn't want anyone else to see them but him.

"I'm not hiding them, I'm just being modest, that's all."

"Why?" Because I don't want people to think I'm a whore. Because I… I don't want Todoroki to see them…

"Kacchan." He rolled his eyes and growled, letting me finish putting the shirt on. I did, snapped the collar in place, and then put the rest of my school uniform on. "I don't know what everyone is stressing about, it's not that noticeable."

"It's very noticeable Deku." Kacchan said rolling his eyes, picking up my notebooks from the floor and shoving them in my bag so we could go.

"Wait, I need to take a suppressant." I said, running over to my desk, filling a syringe. "Will you help me?" I asked, untucking my shirt.

Kacchan rolled his eyes. "I'm not good with all that omega stuff." He dismissed. I felt my heart fall. It would have been really nice of him to have helped me.

"Right." I said, giving up and just doing it myself. I've done it myself lots of times, I just always seem to bruise myself when I do. It's a lot easier with someone helping me.

"Why not just ask for the auto injectors?" Kacchan put in.

"They just scare me, that needle goes in really fast and hard."

"Scaredy cat Deku." He smirked.

"Don't make fun of me Kacchan." I said taking my backpack from him then taking his hand. He puffed out his chest and we walked together to school.

"You feelin alright?" He asked a walked the path leading to UA.

"Still a little sore. You?"

"Yeah, me too." By me punching him, it broke his knot. He's pretty bruised, I am pretty torn up… you know physically. "Guess no sex on your first heat with us together." He muttered.

"There will be other heats."

"Yup." I felt his hand heat up a bit at his quirk but said nothing. That when Kirishima and Tetsutetsu ran up to us.

"Hey guys."

"Hey."

"Izuku you got a collar, holy shit man!" Kirishima said slapping me on the back and looking at it, pulling the collar on my shirt to see it.

"It's not that noticeable is it?"

Tetsutetsu stopped himself from laughing, not very well by the way. "I mean yeah, but it's really nice man. Momo made that for you? It's beautiful!" Kirishima marveled.

"If you like it so much, maybe I should ask her to make one for you." Tetsutetsu murmured. Eijiro blushed bright red. "And I'd happily wear it… if that's what you wanted." It was Tetsutetsu's turn to blush. Kacchan glared at them both. I suddenly felt like we were seeing way too intimately into their relationship. Kacchan squeezed my hand, probably thinking the same.

"We'll see you guys in there." Kacchan grumbled, pulling me a little faster as the other couple stopped behind us. "See what that damn collar is doing?"

"Making Kirishima and Tetsutetsu have a conversation?" I countered.

"I wish we had a fuckin conversation."

"You lost your right to have a conversation about a collar when you tried to not give me a choice to have a conversation about being claimed."

"You said you were mine. Seems pretty crystal clear to me."

"And I am yours. I'm just not ready for it to be so permanent yet." Kacchan clicked his tongue but said nothing. So, our relationship is sort of started off on a rough patch. A substantially rough, rough patch. I'm just hoping we can make it at this point. Class was… weird. I'm not sure if I was making it up in my head or if it actually happened, but I felt like everyone was staring at me. You can only see a few centimeters of the collar sticking out of my uniform, I don't think it's that obvious, but I guess it might be. I don't know. Maybe I'm just imagining it.

I wasn't imagining the locker room, however. As we changed for hero training, the alphas noticeably shied away from me. Yeah, that definitely happened. I can't believe a collar makes them that uncomfortable. I shook my head and as I was walking out in full uniform, I noticed Aoyama talking to Koda and Kaminari fairly expressively, holding up two fingers about a foot apart from one another.

"He's fucking huge! I could barely get the whole thing in my mouth!" Huh?

"Did you have sex with him?"

"Well no, he literally would have tore me in half he was so big! But he seemed to be a pretty enormous fan of blow jobs." Who are they talking about?

"What's up guys?" I asked the other male omegas, coming over to them.

"Deku, why didn't you tell us!" Denki said, smacking my back.

"Tell you what?"

"Because he wanted to keep the secret to himself!" Yuga gawked, closing his locker door.

"What secret?"

"That Todoroki has a massive cock!" I felt myself stop breathing. When did he? How would he? Did… did Shoto h-have ss-sex with Aoyama? I felt like my heart was breaking all over again. I couldn't breathe. I just shook my head, I had to get out of there. I basically ran out of the locker room, putting my hands on my knees, and taking deep breaths, which were… admittedly a little hard with the collar. Why am I reacting like this? Why should I even care who Shoto sleeps with? I'm with Kacchan. I chose Kacchan. My head is so messed up right now, I really… I really have to get it together. Suddenly I felt a warm hand on my back.

"Are you alright?" I looked up and into dichromatic eyes. No, I was certainly not alright.

Shoto's P.O.V.

I don't know what possessed me to touch him. What possessed me to ask him if he was okay. But I did. Now here I am. Looking at my frantic, distressed ex-boyfriend. My ex-boyfriend that was in heat. My ex-boyfriend that I was still in love with. My ex-boyfriend who is now dating Katsuki Bakugo. My ex-boyfriend who for the first time today was wearing a collar.

"Yeah, I'm fine." He squeaked though it was obvious he wasn't. I looked him over. The collar was not noticeable under his hero uniform, but I got a good look at it as he changed earlier. Why would he suddenly decide now was an appropriate time for a collar? Was Bakugo forcing him? He… when we were together, he never so much as hinted he wanted a collar. If he did… I… we just never had a conversation about it. Not once! Now he's dating Bakugo and instantly wearing one? What does that even mean?

"You're certain?" I asked before the air became awkward between us.

"Yeah." He said swallowing, attempting to regain his composure. "Thanks though."

"Your collar is… nice." I felt myself say. I saw his eyes widen, moving to his neck. "I noticed it earlier." I added, realizing his insecurity.

"Oh." I wanted so badly to ask him why he was wearing it, but I held my tongue.

"Well, if you're okay." I said moving to leave, he nodded with a small half smile. Why did I ever come over and speak to him? It felt like the hole in my heart had reopened. Not that it was ever healed to begin with. The rest of hero training it was hard to focus. I was thankful my classmates didn't notice. After a much-earned shower, I began my homework and was nearly through when I heard a knock on my door. Answering it, I wasn't expecting to see Shoji and Tokoyami standing in my doorway.

"Hello."

"Hey! We were just about to head over to Sato's room."

"He's baking a cake and we got some beers and stuff. Thought we could hang." And you wanted me there? I suppose it is a Friday night, though I'm still uncertain why my presence was requested, I decided to join them. We walked over to Sato's room and it smelled heavenly as always. Betas and Omegas seem to swoon over him for his baking ability, he should have no problem finding a good mate. We walked inside and got comfortable. I'm not sure why I came, I was anything but comfortable in groups, this being no exception. The other alphas obviously had a repour, cracking jokes and laughing with one another. I merely sat in the desk chair, sipping the warm low-quality beer as I listened to their banter.

"So, Todoroki, how was that blowjob from Aoyama the other night?" Shoji asked from a mouth of one of his dupli-arms. It was… blissful. The whole situation was, I've been craving the sensation ever since, but I don't think it was the omega's doing, not in the least.

"It was fine." I replied stiffly.

"The dude's throat game is for real, but you should really try his ass. When he's in heat, oh man." The other two alphas snickered at Shoji's words. I should try him? Are my fellow alphas that devolved? It just happened at the party the other night, I wasn't in control of my hormones. But Aoyama deserves more respect than just that. Somewhat slutty behavior or not.

"Aoyama's a whore, I'm not interested in catching whatever he has." Sato laughed.

"Bro I second that."

"That's why you're going after Koda, a pure omega right?" Shoji said to Tokoyami.

"Not when I'm done with him." Dark shadow smirked, as he took a sip of beer. I was thoroughly disgusted by the conversation but felt oddly compelled to continue listening. Is this how alphas really speak to one another about lesser dynamics?

"You see Midoriya's collar today? Is he trying to repurify or something?"

"Yeah, didn't you deflower dat ass Todoroki?" I crossed my arms looking away. I was very uncomfortable talking about my ex like that.

"Oh come on, don't be like that!" Sato started, "It's just… weird you know? Doesn't wear one for you, but the second he gets with blasty, he asks Momo for one. It's weird right?"

"It is weird." I confirmed softly.

"I think Bakugo's forcing him to. He's always been a selfish prick. Probably doesn't want to claim him just yet because he's still banging Kirishima on the side, so he's making him seal himself off to other alphas."

"Damn lone wolf." Bakugo's possessive sure, but I find it hard to believe that Izuku would just go along with that. Well, I find it hard to believe that Izuku is wearing a collar in the first place. We never even discussed something like that when he and I were together. He didn't bring it up. I was nearly positive he didn't want one. Maybe I didn't know him as well as I once thought.

"Tet still punishing Red Riot?" Tokoyami asked.

"Punishing?" I asked.

"Yeah, he won't knot him. He's absolutely disgusted that he was ever with Bakugo, and now he won't sleep with him until he serves some kind of penance." Wow that's… petty.

"Bakugo ruins everything." Sato said.

"Finally, something I can agree with." I smirked. They all looked back at me smiling.

"See now that's why you're the head alpha around here."

"Head alpha?" I questioned.

"Well yeah, you're only the strongest alpha in our class."

"Bakugo's number one." I added.

"And he only hangs out with betas and omegas because he can't command the respect of alphas. You can and do, like all the damn time." I was surprised, I hadn't even thought of that.

"But he stole Izuku from me." I blurted out, unable to hold it back.

"Like a little bitch." Tokoyami said crossing his arms.

"Deku's loss honestly." Midoriya's loss? Are they serious? It's my loss. I lost him! I wasn't good enough to keep him. I didn't try hard enough. I don't understand how anyone could see it any other way. My head hurt, I just couldn't understand what they were saying anymore. I thought it was best to headed back to my room. I politely said my goodbyes and headed back to my dorm. My heart just… tore open. I… I spent the rest of the evening crying. I wish I knew why.
