Armin x reader oneshots and lemons

Armin x pregnant reader

(Y/n) POV
I've been keeping a big secret for awhile from everyone especially my long term boyfriend Armin Arlet, I have been keep this secret for three months, it's not easy keeping it for this long as I've been gaining weight and people are begining to notice.

*flashback*
"Hey um (y/n) should you be eating so much?" Mikasa asks "what do you mean?" I reply munching on some bread "well you've been gaining some weight you need to stay fit to fight" she says, I panic a bit as I don't want her to know the real reason "ok I'll stop eating" I say sadly putting down the half eaten bread. "*sigh* I'm not trying to be mean (y/n) I just want you to be able to fight the Titan I don't want to loose anymore family" she says sadly. Me, mikasa, eren and Armin have all been friends since we were kids, me and mikasa are like sisters. "You won't loose me mikasa" I reassure her.

*flashback over*
This brings us back to our current situation, me laying in my bed staring at the wall, wondering what to do, I know what I should do I should tell armin, but I don't have the guts and no idea how it's not like I can't just walk up to him and say 'hey armin, I'm pregnant' the shock alone would probably kill him. "*groan* what should I do?".

Later in the day
Slowly I drag myself down to the mess hall, exhausted even though we didn't do much that day. I enter, grab my food and sit down slowly eating pieces. When a certain blonde sits next to me."hey sweetie, how you been I haven't seen you much recently, if there's something bothering you, you can talk to me" he say grabbing my hand with his kissing the back of it. "I'm ok Armin, just tired" I lied "ok now I know something is wrong, you only call me by my name when something is wrong" busted. Dam what should I tell him, I don't want to tell him in the mess hall. "I'll tell you later ok?" I ask hopeful "ok sure" he agrees.

Later
It was now night time and I'm wondering if I should go talk to armin I can't keep this a secret forever, my stomach is just gonna keep growing and in 6 months I'm gonna pop a baby out. I've decided I'm gonna suck it up and tell him.
I get out of bed and head to the boys barracks and head to armin room which he shares with eren. *knock knock* anxious I wait for the door to open, it slowly swings open to revel eren in his night clothes "oh hey (y/n) what are you doing here?" Eren question "I need to talk to Armin it's really important" I reply "oh sure come in" he say stepping out the way so I can walk in. I look to the bed to see armin laying in his bed on top of the covers reading a book, he's wearing a simple loose blue shirt and black loose trousers, he looks over at me and smile, he's to cute I hope are child gets his looks "hey how come your here, not that I'm complaining, it's just you never visit at night" he stutters scared he made me think he didn't want me there " I know I just have something really important to tell you, it's why I've been acting so weird" I say as I sit next to him on the bed. 
"I'll give you guys some privacy" eren says as he takes his leave closing the door behind him.

I take a deep breath, as i start getting really anxious, as many thought run through my head 'what if he doesn't want a baby' 'will he leave me?''will he hate me?' I quickly start to panic my breath quickens "hey, hey it's ok calm, oh come here" armin says noticing my panicked state, he quickly pulls me into a tight hug "sorry" I whisper into his chest "it's ok baby" he whispers, at the word baby I can't take it and I just breakdown and start sobbing into armins chest. "Wow, wow what wrong? Please tell me your really scaring me" armin says worry clear in his voice "I'm sorry, I'm sorry I'm such a bad girlfriend" I sob "love tell me" armin pleads "I'm pregnant" I sob "what?! Are you serious?!" He say pulling away holding my arms making me look into his eye, I lower my head "Yes armin, I'm pregnant I'm sorry" I say waiting for him to get mad "oh love don't apologies, this is amazing" he says, he places his hands on my cheek and starts planting kisses all over my face "this is amazing, I'm so happy" he says happy tears rolling down his cheeks "how far along are you?" He ask his face full of curiosity "thr..three months" i whisper "THREE MONTHS?!" He shouts shocked. "I'm sorry, I was just scared that you would hate me or leave me or..." "no I'd never leave you, I'm so happy to start a family with you." Armin replies smiling, pulling me close in a tight hug "I'm gonna be a dad I can't believe it" he mumbles.
Slowly armin leans back falling back onto the bed, me still in his arms. " I love you (y/n) I will never leave you and I can't wait for us to become parents" "I love you to armin, thank you for staying."
