I looked at my mates. Katsuki was drawing another commission drawing and Sero was doing homework. Dabi was watching tv with Miko braiding his hair. I smiled and turned on the tv one of Sero's favorite Little shows turned on. He was hyper focused on the tv. "Sero, come here." He abandoned his homework and crawled to the couch. "Yesh?" I smiled and picked him up and pulled him into my lap. "Baby, is that Little you?" He nodded and pressed his face to my scent gland. I could smell his preheat pheromones, they were turning me on. "Hey. Sero, calm down a b-bit." He started to nuzzle my neck innocently, god, he stopped and just held his face against my scent gland. "Sero, a-are you trying to get Daddy to touch you in a Big way?" He whined and nodded. I let out a breath and said "No, you're in preheat. I can't right now, bud Daddy will when it's safe." Sero sat up and I smiled. "L-Later. God, I think you're in heat and rut at the same time." He ground his hips against me and I growled. I took him upstairs and put him in the heat room. I gave him a kiss and left. I ran downstairs and panted, holy fuck. I looked up and said "We need that appointment now. He's gonna drive me into rut." Dabi nodded and said "Okay." Katsuki walked over and asked "D-Do we want to see about d-doing things in Little Space?" I nodded and said "I'm okay with it. Sero's obviously okay with it. What about you two?" Miko and Dabi nodded. "Sure. I don't mind. Miko?" Miko smirked and said "As long as I don't have to be Little." I smiled and said "We wouldn't force you. And if you want to experiment later on we can." Miko smiled and asked "Katsuki, can I steal your hair tie?" He took the small hair tie out and passed it to Miko. I smiled and sat down. "So what are we gonna do without him for a week or two?" Katsuki gasped and said "I didn't even think about that!" I smiled and opened my arms for him. He slumped over and said "I'll miss him." I nodded and said "None of us can visit either." Katsuki whined and I kissed him. "Shh, he'll be out soon." I pulled out my phone and said "Okay. What specialists did you three go to get the test? I went to Blue Bridge." Dabi smiled and said "Same." Miko shook his head. "No, I went to Grey skies." Katsuki shook his head. "I went to the Children's Hospital." I nodded and said "So we look at reviews for each and whichever is higher we set an appointment there." They nodded and I looked it up. "B-Blue Bridges." Miko nodded and said "We trust you. But aren't they an Alpha speciality office?" I nodded and said "So we should go to Children's then?" Miko nodded. "We could only afford Grey skies so I don't expect a high rating." I smiled sadly and said "It's closed due to no staff and low funds." Miko nodded and said "I don't doubt it." I took a deep breath and said "Blue Bridges has a better rating and with the flu right now I'm not sure he should go there. If something's off or odd I don't want him to have to go through lots of tests. At least not until he's ready." Katsuki nodded and said "Okay. We can go to Blue Bridges." I nodded and said "T-Thanks. We need to ask Sero first." They all nodded and Miko smiled at me. "How about we take a breath and watch a movie?" I nodded and took a few deep breaths and calmed down. "Kirishima?" I looked at Katsuki and he smiled. "We love you." Dabi kissed my cheek and I smiled. Miko grabbed my hand and smiled. "We all love you, especially our goofy Sero." I smiled and wiped my eyes. "I love you guys too." We sat and watched Disney movies all night. I went to get a snack after our fifth movie ended and a small bunny ran between my legs. "M-Miko?" The bunny pressed closer to my leg and nodded. I smiled and picked him up. "Hey cutie." I carried him and gasped with a fablous idea. I took my hoodie off and put it on backwards. I picked Miko's bunny form up and put him in the hood. I smirked and Miko pressed our foreheads together. "Can we stay like this?" I nodded and gasped as a snake started to make it's way up my leg. It pushed my pocket out and made it's way up to the bunny. I grabbed it's head and it wrapped around my hand gently squeezing it. I pressed our foreheads together and the snake chuckled. "Hey, it's me Baby Cheeks. Shh. I'm not gonna hurt Miko." I nodded and loosened my grip and let go. He curled around Miko gently and I smiled. He's okay. I saw Katsuki run over and I smiled "You too?" He nodded and shifted to the itty bitty Fennec Fox he was and jumped into the hood of my hoodie. I smiled and said "Now we need Sero." Dabi affectionately squeezed my arm and I put them on the ground. I took my clothes off and shifted. Miko sat in shock and Katsuki came to hide himself in my mane. Dabi tucked himself under my arm and when Miko finally came over hid in my mane. I smiled and laid my head down so I could feel everyone. I started purring and fell asleep.
*One week later*
"Can we see him?" I nodded and said "Yes." Katsuki gasped and jumped up I went up the stairs first with Dabi making sure nobody fell. I knocked on the door and Sero screamed at me. "LET ME OUT ALREADY!!" I opened the door and he wobbled over to me. "I-I need a bath." He nipped my neck and said "And maybe you can fuck me too." I picked him up and said "No." I took him to the bathroom I set him in the tub and said "Go for it." Katsuki and Miko ran in and climbed in with Sero. "Hi baby!" I smiled and Dabi pulled me into the hallway. He pinned me and started to kiss me. I submitted. I let him take control and it was nice. He pulled away and said "Sleep, you need it. I know you stay up all night worrying. Go nap. I'll take care of them. I love you." I smiled and said "Thanks but I can take care of them." Dabi pressed me against the wall with more force. "No, you will sleep and relax. I've got them. They're my mates too. Go sleep, you're my mate and you need care." I gave, I'm so tired. "Okay." I went to the bedroom and didn't even get under the covers. I was so exhausted.
"K-Kirishima?" I looked at Sero and smiled. "Yes?" He looked at his hands and asked "Can you take me to the bathroom? I-I don't wanna go by myself." I smiled and took him to the bathrooms. "I can't go in." The bathrooms are sorted by secondary gender here so I can't go in. "I-. Okay." I kissed him and he went in. He came out a few minutes later and I smiled. "You okay?" He nodded and said "W-We need to get back now." I nodded and walked to the winter blankets section. "Miko, one blanket. Only one." He groaned and said "I want them all!" I walked over and said "Miko, one." He huffed and pulled out one with Manatees. "Mine." I nodded and said "Put it in the cart." He did and I smiled. "Good." I kissed his head and he asked "Can you carry me?" I shook my head. "No, we're in the store. I will hold your hand." I walked up to Katsuki and Dabi and he asked "Where'd you go?" I smiled and said "I had to pee." Sero hid behind me and whined. I looked at him and let go of Miko's hand and put both my hands on Sero's face. "Hey, Sero? What's going on baby?" He whined and said "M-My stomach is twisting and turning and I feel sick." I nodded and picked him up. "Hey, Sero needs to go home now. I'm gonna take him. Sero shook his head. "W-Want Dabi. I nodded and said "We'll all go." Sero shook his head. "No, j-just Dabi." I nodded and he gave me the list. "Here. I'll take him." It hurt a bit but I let him go. He's in good hands. Miko hugged me and said "Dabi's warmer, the heat will sooth him." I nodded and said "Okay. I finished shopping with Katsuki in the cart and Miko walking between me and the cart. I checked out and we went home. "Can we call them?" I nodded and gave them the tablet. "Here. I'm gonna go to the bathroom." I went and pulled out the thermometer. I was normal. As always. I sighed and looked at myself in the mirror. I saw a person, I'm not quite sure who. I heard a knock and jumped. "Y-Yeah?" Miko giggled and said "Dabi wants to talk to you." I nodded and stepped out. I took the tablet and put a fake smile up. "Hi, how is he?" Dabi smiled and said "Good, he's been admitted and they think it's his Omegan side developing." I nodded and asked "Is he okay?" Dabi nodded. "Yeah, he's asleep. Tell Miko to wash that blanket before he uses it." I nodded and put myself on mute. "Miko! You better put that blanket in the wash!" He gave me a thumbs up and said "In the wash." I nodded and said "He said he put it in the wash." Dabi nodded and said "Good. What are you doing for dinner?" I smiled and said "I was planning on m-making sandwiches and some salad?" Dabi shook his head. "No babe. They need more than that. They won't survive off small stuff like that." I nodded and kept my head low. "Hon, how about you make burgers, corn, salads, and have some small chips and then have them each eat two burgers." I nodded. "Okay. I-I should get started. When will you be home?" He looked away from the camera and said "I'm not sure." He hung up and I nodded. I went to make a better dinner for my mates because I'm so stupid to think they'll be able to eat small. I put the burgers on the grill and went to get the corn. I put it there too and started making salads. I served them and flipped the burgers and corn. I pulled bowls out for chips and then got all the dressings for the burgers. I pulled everything off the grill and made sure it was cooked, it was. I served it up and said "Miko, Katsuki, dinner's ready." They ran over and Miko smiled. "Thank you! I love burgers." I smiled and said "I-I'm gonna head to bed, I'm not hungry." Katsuki looked at me and asked "Are you okay?" I nodded. "Yeah. Yeah, I-I just need some time. If you want to cuddle I'll be upstairs." They nodded and started eating everything. I went upstairs and looked at myself in the mirror, pathetic. "I can't even take care of myself half the time, how am I supposed to take care of two Omegas, an Alpha, a person who's potentially all three sub-genders, and myself? God, I'm pathetic, useless, a waste of space aren't I? My mate doesn't even fully want me anymore. He only wants me because he can't leave everyone else. God, why can't I do anything
right?" I took a deep breath and said "I'm fine, lay down." I walked over to bed and took all my clothes off and curled up. I heard a knock and turned. "K-Kirishima? C-Can we come in?" I nodded. "Yeah. You don't need to ask." Katsuki and Miko walked in and I sat up. "W-We heard everything. You're not pathetic, or stupid, you care for us better than we deserve. We love you and Sero does too. Dabi does too, more than you think." I smiled shakily and said "Thanks babes, let's lay down." Miko nodded and Katsuki grabbed my face roughly and kissed me. "I love you. You are perfect. You may be odd but I love you, even before we had the bond. If everyone left I'd still be here." I wiped my eyes and said "Thanks." I laid down and Katsuki and Miko hugged me. I fell asleep feeling sad and angry.
