MIDORIYA

I put the shirt up not wanting the scent to be on me, chances are slim but I don't want to take that chance. By the time Mirio arrives, I'm hard, leaking, and panting slightly. I held on pretty well if I say so myself. I was at least able to open the door and allow him into the apartment. He puts the food up and comes directly to my room.

"I let Iida know I'm in heat," I explain. "I have room guards so we should be okay." Mirio is almost at his not thinking point as he doesn't even respond to me. He removes his clothes in hurry grabbing my face kissing me aggressively. I try to return the kiss but he is so hungry for it I can't even gain a little bit of control. "Whoa…." I pull out of the kiss sitting on my bed. Mirio just growls at me with this hungry look in his eye. Shit….is he in a rut?

Most of the time Mirio prefers to not mate me during his ruts because he can get pretty forceful and he doesn't want to hurt me. I informed him that is an alpha nature and it's okay to be aggressive during that time but he won't hear of it. I use to think he was overreacting but I respected his wishes. Now I can see what he meant and we're just getting started. Mirio pushes my legs back which forces me to lay back on the bed. Wait, this is happening way too fast.

"Mirio…"I cry. "Condom…." He growls not liking that I'm telling him what to do. I know this is more his alpha side than him. He is alpha in rut and I'm omega in heat. I shouldn't be demanding anything of him as far as his alpha is concerned. He slides inside of me filling me up quickly. "A-ahh….." Mirio begins to thrust his hips grunting. My eyes flutter my omega liking the idea of an alpha filling me up but something seems off. I don't feel the relief that usually comes followed by pleasure. Mirio grabs on to my hips to limit my movements from his forceful thrusts. For the first time in my life during a heat I feel sick, very sick. This isn't my imagination something is wrong. "Mirio….stop…."

"I don't know if I can," he grits continuing to thrust inside me. "Aaarrggghhh…nnngghhhh…."

"I think I'm going to be sick…."I explain further covering my mouth with my right hand. Mirio starts thrusting harder into me. I'm not sure if his alpha is turned on or offended. I moan as the sickness takes over me. I lean over and starting vomiting on my bed unable to keep it down. Mirio doesn't stop. I lay back down once I have vomited closing my eyes because I feel even dizzier from the movement. I don't feel any better but worse.

"Fuck….ha…..hahh…." he growls thrusting his hips. "Your ass is so good to me…..arrgghhh." He slaps the side of my ass and I yelp trying to keep from throwing up again. I feel dizzy as Mirio continues to mate me. I close my eyes and try to focus on us mating but it is making me feel iller. After a while, I just can't take it anymore. I hate being sick and this is no different.

"Mirio…."I moan. "Uggghhh…"

"That's right….." he moans slowing down his hips. "Nnngghhh…..say my name." There is nothing sexual about this at all. I feel really sick but he is completely out of it. Mirio begins to roll his hips his alpha loving the feel of me.

"Mirio!" I cry. Mirio speeds up again with his thighs slapping against my ass. I can't stop the chunks from spilling from my mouth as my body rejects this alpha. It is very clear that my omega is rejecting him. I lean to the side once again beginning to throw up with my eyes watering. I begin to cough laying back down as Mirio pulls out his dick cumming on my stomach.

"Ahhh….fuck…." he moans as he strokes his climax out. "Damn….." Mirio closes his eyes taking a few deep breaths. He is starting to look like himself. He comes around looking down at me. He glances to my left seeing the vomit before looking back at me again. "Why are you throwing up?"

"I don't know!" I cried sitting up struggling to find my words. "You didn't even help….you didn't stop….you just kept going as if nothing was happening." I can't stop the tears from flowing. This mating was not pleasurable for me at all. This was almost terrifying. I am hoping it is not my omega rejecting his alpha…..what am I am going to do. Why would this happen now? I close my eyes praying that things will work out.

"I'm sorry," says Mirio. "I….I don't know what to say." My body doesn't feel sick anymore but I'm starting to feel the ache. I swallow hard before sighing.

"I'm hurting…."I mutter.

"Let me change your bedding," he suggests. "It's the least I can do." I can smell the guilt pouring off Mirio as he changes my bedding while I sit at my desk shaking from the need to mate. I have a towel in my desk chair to keep the chair clean as I am slicking a lot at the moment. Mirio looks at me holding out his hand now that my bed is completely made. "Come here…" I come over to him sitting on the bed beside him. I'm glad to see he is hard again because I need it. I grab the condom from my nightstand ready to give this a second go. Maybe my omega isn't rejecting him. Maybe I just needed to get this out of my system, whatever this is.

"Before you forget," I inform him handing him the condom.

"At least I remembered to pull out," he says taking the condom. As if that made it okay, I'm going to say that out loud though. He applies the condom and I can see a bit of him disappearing as the alpha in him steps forward. "Turn over on your knees…." That was not a request. I follow his instructions knowing better than to argue with him in this state. I need this more than anything at the moment. I hate being this desperate for dick but I mean my omega was not satisfied with our 1st session. Mirio thrust inside of me again with no hesitation. The sickness is back as soon as he starts rolling his hips.

"Mirio," I cry. "Oh god….trash can." He growls thrusting into me. Oh god, I'm not going to make it. I lean over the side of my bed vomiting on the floor.

"Ah-ahhh…..baby you're so tight….mmmm….." he moans continuing to roll his hips. I'm not even enjoying this as I end up vomiting another two times. I'm so glad when he finally cums. I stumble to my closet falling to my knees as Mirio is panting his alpha satisfied. Well at least someone is fucking satisfied. I can smell Todoroki scent lightly and it makes me feel better as soon as scent him. "Midoriya, are you okay?"

"No, I'm not okay…"I cry. I can feel the tears in my eyes and I know he can see them.

"I'm sorry…." he says.

"I know," I reply scenting how troubled he is.

"Something is wrong," he says. "Let me get this cleaned up and then we will see if we can find out what is going on." He goes to grab the paper towels from my kitchen. I quickly grab my shirt with Todoroki scent smelling it. I feel so much better than I had a few minutes ago. I don't even want to put the shirt down but I do. Mirio walks into the room with the whole paper towel roll. I meet Mirio where he is before he goes back within himself letting the beast take over.

"I need to go to the hospital…"I state tired from throwing up. My heat is rising again but I don't care about that. Soon I'm going to be vomiting bile if this continues.

"I don't know if I can take you when in rut," says Mirio. He shakes his head before looking determined. "No, yes I can! Get dressed, I'm going to fight this." I get to my closet not having the strength to put on anything complicated. I go with a cute PJ set Uraraka brought for me. Mirio gets dressed and I almost fear for anyone on the streets. His rut smells strong and dangerous despite me mating him a little already. "You ready?" he growls.

"Yes," I say lowly.

"Let's go," he says. He reaches his hand out to me and I take it. We head out of my room as Iida is walking into the apartment.

"Hey, I got your…." He can sense Mirio's rut along with my heat. Mirio growls at him and Iida turns his head to the side submitting immediately. Iida is a beta but his alpha doesn't know the difference, it just senses a threat.

"Iida, I have to go to the hospital," I explain. "Please meet us there."

"He doesn't need to be there," says Mirio glaring down at me. "That is what I'm here for."

"I know," I reply rubbing his arm with my free hand to keep him calm. "I want Iida there. You are the head alpha, we know that." I turn my head submitting to Mirio so he not only hears the truth of my words but sees it as well. Mirio seems to be pleased with this and opens the door as we head out. The drive to the hospital was horrible. I can see Mirio struggling to focus with my heat scent filling up his car and him trying to fight his rut. He is not as good at controlling himself as Todoroki was. He had to pull over several times to kiss me, rub his hands on my body. God, what is going on. We finally arrive at the hospital close to campus and Mirio puts me in a wheelchair as I can barely walk at this point. Soon as we enter the hospital several people are looking at us. Omegas are mewling and alphas are growling thinking Mirio wants to fight. Mirio growls protectively wanting them to back away from us. Maybe this wasn't a good idea.
