It has been a few days. We are on the last day of Kirishima rut, thank god. My body still seems to be struggling to keep up with the mating demands of an alpha in rut. I never knew what tired was until now. Even with the rest time it is exhausting.

"Come on," pleads Kirishima. "Let me be on top. I know you're tired." No way am I doing that. I have been trying to avoid his intense glare for days.

"No," I reply looking at the TV. We have 12 minutes before he needs to mate again. I just want to enjoy my rest time in peace. I don't understand why he wants to be on top so badly. Most alphas wouldn't care. They would be glad to just to fuck.

"Will you look at me?" asks Kirishima. I grit my teeth almost wanting to snap at him. At the same time he is my best friend. I can't help it as my agitation shows.

"Man!" I exclaim giving up tossing the remote down. I turn over facing him laying down. Kirishima is sitting up looking down at me. I swallow a purr as my omega is getting excited already. I would sit up as well if I had the energy.

"Is mating me that bad?' he asks.

"What do you mean?" I ask in confusion. I become emotional scenting his sadness. I didn't meant to make him feel like a bad alpha. He is actually great. A lot more caring than I would have thought. "Eijrou you're a great mating partner. Don't worry so much."

"How can I not!" he exclaims running his hand through his messy hair. That spikey gel wore off after 1 day. "You are stubborn. You won't let me help you."

"I don't need help," I defend. I can overcome this. I just need some time to adjust. I refuse to be weak.

"Yes, you do!" he exclaims. "I may not be an omega, but I know about what happens to your bodies. I'm not forcing you to do anything you don't want to do but seriously. You can't keep holding yourself up." He is right but I refuse to admit it.

"I will be fine," I reply. "I got this. I'm stronger than you know. We are in the last day of your rut. The next time I will be more prepared." Next time? Why the hell did I say that. Kirishima scent rises. He clearly wants to mate me again.

"Next time huh," he teases.

"Stop looking at me like that!" I exclaim. I fold my arms turning my head away from him.

"Like what?" asks Kirishima moving closer. His scent is still increasing for more than one reason. He is going to need to start mating again very soon.

"I don't fucking know…" I mutter. "I don't like it though." Th way he stares at me isn't bad but it feels like we are together. We aren't together. I don't need him giving my omega any ideas. Krisihima enters my personal space. He appears to not being taking me seriously. "What? I mean it!"

"Uh huh," says Kirishima leaning in quickly scenting my neck.

"Ohhhh…." I moan. He hasn't scented me at all thus far. There was really no need since I am here mating him. Kirishima scent gland softly carelessness my own. I purr lowly with my dick becoming erect. I didn't know getting scent could feel this good. Kirishima continues to softly rub his neck against mine. My inner omega moves with me enjoying this alpha wanting to please not just me but us both. I whine in pleasure as my mind is becoming dizzy. "Ahhh….." Kirishima slides his left hand over my waist before pushing the covers down. He growls lowly getting a whiff of my slick.

"God I could never get tired of smelling you…" he mumbles before growling. It is taking everything in me not to hump him. I want him buried deep inside of me. Kirishima stops scenting me kissing me neck. I am panting feeling my dick twitching.

"Ugh…" I groan wanting him to scent me again. My heart is going crazy. My body is pining for him as if I am heat. What the fucking hell. I study my vision trying to regulate my breathing. Kirishima leans over grabbing a condom which I am grateful for. My mind was not on that at the moment.

"Do you want me to keep going?" he asks. Is he screwing with me.

"W-what?" I question. I can barely think right now. My mind is on getting that dick. Kirishima sits back on his knees as he put on his condom. He looks back at me.

"I will take that as a yes," he replies. Before I can say anything as his neck is back on mine.

"Fuck…..nngghhh…" I whimper grabbing the back of his head. My hand tightens as I try to keep my breathing even. My omega loves that he is scenting us. He wants us to walk around smelling of him. The scent is so strong no other alpha would dare approach me. They are more likely to believe I am bonded. This thought pleases my inner omega. I murmur lowly as I begin to lightly roll my hips against Kirishima wanting more closeness. Kirishima snarls feeling my throbbing cock against his abs.

"Katsuki…" he groans rolling his hips. He enters me taking my breath away. I gasp before purring loudly. I arch my back as the fighting the climax that threatens to take me already. I take a shudder breath as I look up at Kirishima. He growls lowly before rolling his hips slowly. I cuss under my breathe as this feels more intense than anything I felt up until now. Kirishima is digging deep. The movement is fierce but strong. Right up my alley. "Ahhh…..ahhh…." he moans leaning closer to me.

"Ejirou…" I whimper. I know what's coming. I am doing my best to fight it, but I can't. That scenting alone could count as foreplay. Kirishima closes the gap between us claiming my lips. My inner omega purrs immediately in satisfaction. I moan parting my lips seeking out more from Kirisihima. He grumbles lightly before sliding his tongue between my lips. My body trembles lightly. I begin to softly rock my hips. Us moving together in this way allows him to go much deeper than he previously was.

"Katsuki…..fuck…" he whines. I know my ass is giving him the meanest grip. Kirishima continues to kiss me as his hips speed up. He is making me bounce on his dick. I toss my head back out of the kiss trying to catch my breath.

"Hahh!" I cry. My eyes flutter as I feel my climax climbing my spine now. Explaining that tingle, that slight fluttering and heat I feel inside. I can only describe it as pleasure and madness into one. Oh my god. "Ggaahhh…s-slow down…."

"Hell no," growls Kirishima. "You're about to take all this dick." I mutter feeling my ass spasm at his words. Kirishima is no talker and I know for a fact he is doing to deliver. Kirishima left hand grabs my hips as he continues to thrust hard and deep. He is hitting my spot making me howl. I almost don't even recognize my own voice. "Yeah…"he moans. "Take that shit…." I curve my back shaking.

"Hahh…." I cry digging my nails into back. "Ohhh…..ahhhh….." I am doing my best to keep up with him but his speed is too much. I rack my nails down his back as my dick jerks. "I-I'm going to c-cum…ahahh…haaa…."

"Yes…" pants Kirishima thrusting away. "Yesss….ahhhh…" My body shudders making me whimper. The heat I begin to feel causes me to gasp. I literally feel hot over. I almost wonder if I am going into heat. Fucking hell….

"Haaa….shit…"I hiss. Kirishima growls before I feel him biting on the side of my neck. My eyes widen as my body begins to climax hard. I dig my nails into Kirishima back from the intense pleasure. "Aaaaggghhh…" I buck my hips as my body chases this pleasure.

"Mmpphhh…." growls Kirisihima into the bite. He is still thrusting his hips.

"Hahh…" I cry feeling my cum soak his stomach. My leg begins to shake. "Oh god…oh god….ahhhhh….." My hips begin thrusting into Kirishima as he slows down still growling. I open my eyes but can't see anything but white. "Ugggghhh….." I am looking around when the imaging slowly starts to clear. I can see Kirishima shoulder as he is still attached to the side of my neck. I'm breathing hard trying to recover. He didn't bond me, but he could have if I wasn't paying attention. This was….incredible. "Ejirou…."

Kirishima growls into my neck. I know that fucking twitch now. He is releasing his orgasm now. I thought he came already. Kirishima rocks his hips softly. My eyes close shut as my quivers under him.

"Man….ahhhh…." I moan as my eyes flutter. He's going to make me climax again if he keeps going. Kirishima finally stills his hips, but he doesn't release my neck for 20 minutes. I relax into the bite as it doesn't hurt. I find myself feeling surprisingly comfortable.

"I'm so sorry," he apologizes. "Shit…..stay right here." Kirishima pulls out of me causing me to gasp. He grabs some paper towels from his nightstand. He begins to press them into the side of my neck. "I'm sorry. I wasn't trying to bond you…you just smelled so good, you felt unbelievable….different…." I continue to look at the ceiling because he is right. This felt distinct.

"I get it," I reply. "Just try to control yourself. I'm not trying to buy a fucking collar." Kirishima chuckles.

"I can't be mad at you for that," he replies. "They do look pretty weird. Glad I don't have to wear them." I roll my eyes being reminded that if I was an alpha I wouldn't have to worry about this bullshit. "You did good though….my alpha is pleased you marked me."

"Say what?" I ask. "What are you talking about?" Kirishima stops applying pressure for a moment. I place my hand over the paper towel that is covering up the bite he gave me. Kirishima turns around allowing me to see his back. Holy shit. I can see the blood running down his back. I remember digging my nails in but I don't remember scratching him like that. Looks like he got into with a bear. "Why didn't you use your quirk?" He faces me taking over applying pressure on my neck.

"Why would I do that?" he inquires. "You are the fiercest omega I have ever mated. Alphas dream of this shit. I can't wait to show it off."

"What!" I exclaim. Please tell me he is joking. He chuckles and I know he isn't.

"I won't tell them it was you," he replies. "Clearly you are uncomfortable with this." I don't say anything because he isn't wrong. "Um so my alpha seems more satisfied in the missionary position. Is it okay if we do it again?" I really don't want to, but it did feel damn good.

"Whatever," I mutter dropping my eyes for a moment. "I guess." Kirishima gives me that big goofy smile. For the love of god…
