Tsukishima Kei x Winged Trans Male Reader

Tsukishima walks in on too many secrets because he doesn't know how to knock
*********
You woke up with a yawn, your hand covering your mouth as you sat up. Your bare feet made contact with the floor, a shiver going up your body as you jumped back into bed. 'Damn cold floor, leave!' You thought as you reached for your dresser, getting the drawer open but not able to grab the socks. You groaned as you tried again, almost getting the socks before you lost balance and hit the floor with a THUD, your wings puffed into the air. "(Y/N)? Are you okay?" You heard your mother yell from down stairs, getting up with a groan. "I'm fine, mom!" You yelled back as you got up from the cold floor covered in goose bumps. You stretched your body, your wings twitching as they stretched out with a couple feathers falling.

You checked the time, seeing 11:45 AM in big red laters on your alarm clock. You grabbed your clothes and opened your bedroom door, making your way to the bathroom and grabbing a towel on the way. After your morning routine, you dried off, taking extra time to make sure the lumps of feathers on your back were completely dry. You dug through you clothes for your binder, only realizing you must've left it in your room when you didn't see it in the clothes pile. You wrapped the towel around your lower parts and held your clothes to your chest, opening the bathroom door and making your way to your room. "(Y/N), I'm leaving now! Behave!" Your mother yelled, "Okay!"

You closed your door and dropped the clothes on your bed, grabbing the binder that was two sizes too big to help conceal your wing. You got the binder down to your shoulders before you heard the door open, "(L/N), I got the note- Oh." You stared at each other, Tsukishima more staring at the two giant wings on your back. "I can explain."

After you kicked Tsukishima out of your room and got dressed, you walked downstairs to see him patiently sitting on the couch. "Holy shit, you're still here?" You asked in bewilderment, "You said you could explain what I saw, so yes." He looked confused by your question before shrugging it off, notes decorating the table in front of him. You sat beside him, "So, how much did you see?" You nervously asked, mentally facepalming at how stupid it was. But you couldn't help but worry, sure it's terrible he found out you had wings, but finding out you weren't even born a man? No thanks. "I saw it all, it's a little hard to hide wings." You sighed in relief, praying he doesn't say anything else. "Now, for my explanation."

"Well, uh," You nervously scratched the back of your head, "What do you want to know?" He stared at you with a Are you stupid? face, and you were, indeed, stupid. "Why do you have wings?" You  contemplated his question, "Do you seriously not know?" "I KNOW, DIPSHIT! I'm just thinking." You crossed your arms. On one hand, you do owe him an explanation, but on the other, your mother had always told you to never tell anyone, no matter the circumstances, where you come from. "Hello? Earth to (L/N)," Tsukishima waved a hand in front of your face, "I said I'm thinking! And to answer your question, I don't know. I just do." He didn't seem satisfied by your answer but didn't push it.

"Does your mother know?" Ah, shit. Why is he asking questions you don't want to answer? "Next question," "I'll take that as a no. Can you fly?" It was your turn to give him a Are you stupid? look, "Yeah, they're wings." You both stared at each other with unimpressed looks. "Can you show me?" His question took you by surprise, "What?! No! Do you want the government to catch me?!" Tsukishima looked like he considered it, "Are you kidding me?!"

After a long talk with Tsukishima (which consisted of you begging for him not to tell anyone), you started studying in an uncomfortable silence. The atmosphere was filled to the brim with tension, and not the kind you want. You sat in front of him, both tensed from the earlier interaction and not actually studying. "Can I see them?" You jumped in your spot, "I-I mean you can, but..." He quirked an eyebrow, "But?" You looked back down to the paper, "Well, it's a really uncomfortable process where I have to get undressed- which means I have to off this big comfy sweater and I don't have any shirts that let them breath so-" You ran out of breath, talking so quickly you didn't notice the Tsukishima smiling.

"You can just take it off, you know." "No, I can't! I mean, no, I can't." His eyes widened at your outburst for a moment, returning back to normal, "Okay, I don't judge." You couldn't tell if he was being genuine or not, but he didn't push on.

You two mostly studied in silence, only making an occasional comment to each other about a problem one of you had trouble with. "So, is there a reason?" You almost slammed your head on the table, "There is a lot of reasons. First off, my mom will kill me if she found out you know I have wings. Second off, if anyone finds out I'm a freak, who knows what'll happen to me! Third off, I..." You paused. You shouldn't. "I just can't, okay? Leave it alone." Tsukishima stayed silent for awhile, you both going back to silently studying. "I think it's kind of cool," You heard him mumble, "You... you do?" You looked at each other before both looking away, bashfully. "The wings aren't lame," He said a bit louder.

You smiled, looking outside to see the moon. "Holy shit!" Tsukishima looked outside to see it was already dark, "Oh, it's late." "Yeah, it is." You both sat there in silence, "You want to see something?" He nodded. You lead him to your backyard, laying down in the grass and looking at the stars. "You see that constellation right there? Corvus?" You pointed, "Yeah?" He was confused on why you would want to show him constellations, "I'm from there," Your hand fell back to your side, "My mom had me there before we had to move to Earth, I was two, I think." Tsukishima turned his head to you, "Why did you leave?" You looked at him, "A war," Was all you said as you looked back at the stars, "Still happening, believe it or not."

Tsukishima looked back at the stars, his hand that was previously sitting on his stomach went to his side, falling on top of your before he flinched away, "Uh, sorry," He said as you laughed, "It's fine. Though, you wanted to hold my hand you could've asked." You laughed as his ears turned red, even in the dark you could see the way he blushed.
