Mama Midoriya (Inko X Male Reader)

Family Dinner

Several months later, Inko is now officially your Extra Thicc girlfriend. Inko's recently broke the news to her son that she started dating again just before he was officially moving out to the Hero College, after some convincing from Izuku's teacher/master All-Might himself. Your first meeting with Inko's son went quite well, as Izuku had recognized you from his childhood when Kacchan was a kid, and he was happy that you were making his mom happy again, given with how lonely and stressed she gets since she was essentially a widow before you came into her life. Judging by how much Inko became in love with you, it was already a relationship that would soon blossom. And would soon blossom even more as today was not only the way that she was celebrating her Son's success as a Hero in training, but was also the day you were officially moving in with her, and was also going to be a little bit of a family reunion. And also it was the holidays, it was Kinrokansha day to be exact.
To celebrate, Inko was in her kitchen making Kinrokansha dinner, There was a knock on the door which started her
"Mom?"
Asked Izuku
"Oh-Im fine honey! Just wait while I answer the door."
Inko turned and ran to the door where she stopped and checked herself, she was a mess, she was wearing her Apron but was nearly covered with food stains from doing all the cooking while her son did most of the house work and setting up the dinner table. Izuku was a bit nervous about the certain family his Step Dad was bringing for dinner. He isn't exactly on the best of terms with Your nephew. In fact, your nephew is Izuku's childhood Bully. 
"Y/N !"
Inko's face lit up in surprise
"Hey darling."
You said then scooping her up and squeezing her plump body into a big hug, picking her up off the ground.
"H-honey!..."
Inko stuttered embarrassed as You proceeded to cover her cheeks in kisses
"I'm a mess!"
"I don't care. Just wanna give my Thicc Queen some love."
"Stoop..!"
Inko giggled now flustered
"Oh, Inko, these are my daughters, Kendo and Yu."
Inko looked up to see Your two girls standing behind You, and became even more embarrassed and flustered.

"Oh my goodness, hello you two!"
Inko hurriedly got down and bowed, as did they
"Hey mo- I mean Ms. Midoriya."
Kendo bowed
"Afternoon Ms. Midoriya."
Yu bowed
"My it's so good to see all, come in!"
Said Inko
Kendo and Yu walked in and said hi to their step bro, Izuku. Kendo playfully teased him and got him in a headlock with her muscles.
"Honey? You wouldn't mind giving me a hand with dinner would you? I—if it's no bother.."
Inko asked
"Oh, of course babe."
You said
"Damn it mom!! Let go !!"
A boy shouted from outside the front door and was interrupted by an angry female voice.
"Ah. I believe my family has arrived."
You said
"Oh boy..."
Inko became nervous
"Don't worry honey, I promise she won't bite."
You squeezed Inko's hand and gave her a kiss on the cheek.
You then answered the door for your sister, brother-in-law and nephew.
"Y/N!!"
Mitsuki grabbed you into a headlock and rubbed her fist on top of your head
"There's my little brother!"
"Damnit Mitsuki!.."
you grunted as they walked in
"Aunt Mitsuki!"
Kendo said running to her
"Hey kiddo!"
Mitsuki scooped her up
"What?! Kacchan!?
Izuku said shocked
"Yes, Izuku. Katsuki Bakugou is my nephew. Which means Mitsuki is my sister."
You said with a sound of disappointment in your voice
"What !? No way...does that mean...KACHAN IS MY COUSIN NOW!?"
"Make that twin sister. But I'm 4 minutes older."
Mitsuki then playfully nudged you
"Oh, hello! You must be Y/N's sister? He's told me a lot about you."
Said Inko
"Uh, who's the fat chick and the nerd ?"
Mitsuki whispered
Inko heard this and immediately exams embarrassed, she looked away with her cheeks as red as tomatoes, You scowled but answered her
"Mitsuki, That's Inko Midoriya. My girlfriend."
Mitsuki then looked to her
"Hm? Oooh! Wait! I know you! From the coffee shop! Hisashi's ex wife, right?"
Inko became even more embarrassed by her having been reminded of her ex husband.
"Gosh, your so much smaller then I remember, and much more plump I'd say."
Mitsuki said which almost made you want to punch having commenting on her weight twice already.
"OKAY, Mitsuki? Mosaru? Katsuki? Dinners almost ready. Izuku? Why don't you go and train or hang out with Yu, Kendo, and Katsuki while the adults prepare dinner?"
You asked
"O-oh! Sure Y/N!"
Said Izuku as Kendo wrapped her arm around his neck
"Yeah! I've been dying to have a sparring with match with you, you know with that crazy awesome quirk and all!"
Said Kendo
"But...I'm an adult!"
Said Yu
"Fuck off! I ain't hanging out with that damn nerd!!"
Kacchan said in a fit of rage as he made mini explosions in his palms, to which all of a sudden Inko grabbed his wrist tightly, much to the surprise of You, Mitsuki and Mosaru.
"Wha-HEY!!"
"Do. Not. Call. My son. A damn nerd. EVER."
Inko have a terrifying glare at Kacchan.
"Holy shit lady Fine!! Just let go of me!!"
Kacchan's voice cracked at the last sentence as Inko let go and he stomped off behind Izuku, Kendo, and Yu.
"Whoa!"
Mitsuki patted Inko's back
"Damn, bro! I dunno how but you always manage to attract the feisty ones, and something tells me this chicks a keeper."
Inko immediately reverted back to her usual timid and embarrassed state
"Oh! Goodness, sorry I lashed out onto your kid Ms. Bakugou-"
"Hey hey, don't worry, I have to deal with this all the time, it's no big deal. Anyway, guess I should welcome you to the family, Inko!"
Mitsuki then hugged Inko tightly
"O-oh th-thank you!.."
Inko grunted
"Okay, Mitsuki, that's enough."
You said
"What? You worried I'm gonna steal her from You?"
Mitsuki smirked and winked at You
"I'm kidding!"
She bursted out laughing letting Inko as she took a moment to breath.
"sooo your my brothers new fiancé ? Aren't you Kinda short ?"
"Uh...yes."
Inko gulped
"Mitsuki..."
You groaned
"I'm kidding, grumpy. I don't care if you like plump chicks."
Mitsuki then playfully elbows You in the chest and laughs.
