The next couple of days you were in hell since your home room teacher Mr. aizawa said that you had tests and quirk test and work studies coming up you sighed in defeat as you asked the girls with they would like to have a group study session some time to study. 

They agreed so in a month they had group study session in the library it was you, uraraka, sui, mina, Toru, jiro and momo all study for like 3 hours one day and the week after that for 2 hours. 

The next month after that you had couple of test and quirk test you didn't get to see your bf izuku that much cause he apparently your bf Katsuki got into a fight with him oh and your bf izuku didn't start the fight it was your brother when you heard this of course it was him they were both pretty banged up they both had been heeled by recovery girl.

After you got to see him "ah izu are you ok I heard you had fight with my brother" you said to worriedly "aww I'm fine puppy" he said kissing you "then what was the fight about?" you asked him "well you know your brother being your brother again" he said to you "ah so him being a selfish and arrogant boy again" you said to him "look those your words not mine but yeah" he said to you.

You looked at each other then laughed as you snuggle together talking about pro hero's again. You watch him as he would look through his 13 hero notebooks. After that you went scold your brother Katsuki for fighting with your bf izuku. "bro I thought you going to try to be nice with my bf izuku midoriya for me"

you yelled at him "oh shut up sis like hell would I be nice to that damm nerd" he yelled back "oh fuck no I won't shut up Katsuki (middle name) bakugou you go apologises to my bf izuku midoriya right now" you shouted at him you knowing far to well that your twin brother Katsuki hates it when he gets middle named by you in arguments.

"did you just middle name sis" he yelled looking offended you smirk "oh yes I'd did brother so go and apologies to him" you said to him. "fine fine I'll apologies to your bf izuku midoriya sis" he said grumpily as he walk down the hallway with you follow up behind him just to make sure that he doesn't do anything to your bf izuku again.

Izuku looked back over at your brother Katsuki

 "brother go on apologies to him" you said giving him the look of *if you don't I'll middle name you for the rest of your life and I will tell everyone in our class about your middle name too* he gulped at you then looked back izuku.

"izuku I..m sorry for fighting with you" he said to him "well kacchan I accepted it" he said "can I go now sis?" your twin brother asked you "yes you can go now brother" you said to your brother. He left you and your bf alone "so puppy what exactly did you do get him to apologies to me?" he asked you as he  pulls to the bed

 "well i use his middle name, he hates it so much and that feared him into apologies to you'' you  said as he sat down on the bedsheets as you straddle his lap "ah really wow so what is his middle name then?" he asked you "i would tell you but, you would already know it right, i mean you are childhood best friends with katsuki right?'' you asked

as you try to stop him "alright puppy what is it?" he asks you while looking into your red eyes "I was wondering if you wanted to take the next step in our relationship" you said you looked away with blush "I love to you puppy" he said kissing your lips again.

So around Christmas you decided to do it so when everyone was outside at a Christmas bonfire you and izuku sneaked back to his dorms and went up in the elevator to do some homework *cough cough*

"puppy you are really delicious" he said to you kissing your lips.

He pulled down hsi boxers pulling on the condom hovering over you trapping your lips in a kiss again "you ready puppy?" he said "yes I'm ready" you replied. He slowly moved in and waited for you to get use to his size he waited for you give him a sign  you waited for pain to go away you then immediately felt pleasure you nodded for to move.

He started to move in and out of you as you moaned loudly "iz-uku so, good ah" you moaned in his ear "aww does puppy like that" he said in you ear you moaning his name again and again as you left marks and scratches on his back he moved in out of your p$$$$ faster harder you moaned out in pleasure as the room smelt of sex the sounds of moaning, grunt and skin slapping against each other.

You and izuku got your breath back as he got off the bed tie a knot in the condom and put it in the bin next to the desk he walked back to your sleepy figure on the his bedsheets "how are you feeling puppy?" he said to you "I'm OK a bit it sore but I love babe" you said smiling at him he leaned down to trapping your lips in a kiss and said to you "love you puppy" you blushed and giggle at your pet name name  "aww love you to izu" you said to him in the end you stayed the night at izuku dorm until the next day.

>>>next day<<<
You woke to see a your curly green haired bf izuku still asleep you were sleeping on his chest hearing his heart beat going and the rise and fall of his breathing you snuggled into him making sure it wasn't a illusion you felt a arm around you "morning puppy" he said to you "morning to you to izuku" you said as you stayed in bed a while longer until you got up went your dorm room to get fresh clothes when you were stopped by your bf izuku

 "babe what's wrong" you said to him "I got to give this to you when we started dating so, here its yours you can keep it puppy" he said to you hanging you on of his hoodies that said "All might" on it you find him really cute and sweet and sometimes a bit adorable when it comes to him obsessing over his favourite Pro hero All might I have you seen his dorm room.

"thank you babe I will love it forever" you said to him as you took the hoodie you went back to your room to have a shower after that you put on the fresh clean clothes and the hoodie on. You went down stairs in the elevator to see the class in the lounge area  of the dormority. You had breakfast with the class then got dressed into for school when you were at lunch with your friends 

"hey y/n why do you have a bandage on your neck are you alright ribit" sui said to you at the ta le with your bf izuku and your friends sui, tenya, uraraka and todoroki. "oh yeah I got bitten by someone" you said blushing not wanting to answer that you in fact had a hickey on your neck from izuku.

"OK then why are you blushing so much" uraraka asked. you laughed nervously to yourself "oh yeah well I izuku can explain that one for us all right babe" you said to her pointing at your bf. "oh deku what did you and y/n do?" uraraka asked izuku. He "wait what?" he said trying to act dumb he looked at you "what do they want me to explain puppy?"  he said to you. You sighed "about my neck babe" you said to him pointing at your bandage.

"oh right yeah me and y/n were doing home work in my room" he said to the group "oh well I can't stop my fellow class mates from studying hard" tenay said to izuku and while you giggled. "So what kinda of studying did you do then?" todoroki asked to izuku you looked at todoroki back at your bf. "oh well we started with English then went on to math and then Japanese and I think that's was it what are you trying to say?" you ask him 

everyone at the your table looked over at todoroki "well when I was going up to my dorm room I saw you going into midoriya's without any homework at that moment I didn't think of it until I heard loud noises coming from midoriya's room last night" he said as he eat his soba "ah shit we got caught so who is going to tell him you or me" you said to your bf.

"fine I'll tell him" your bf said to you as you went back to eating your lunch "todoroki the noise that was coming from my dorm room was well me and y/n having sex" he said to todoroki you saw the table was in silence. "oh" he said to your bf izuku (a/n well congratulations you and izuku broken him. you both broke a perfectly innocent boy named shoto todoroki).

after your bf told them you and himself saw the shocked expressions on their faces you both laugh but it was short when "ah that's explains the bandages" uraraka said to you "urachan" you whined "yeah that also explains why you said that you got bitten by someone ribit" sui added as well "I was deceived by my class mates" tenya said to the group of friends and shoto went back to eat his soba.

After that you both promised that you would put on concealer next time you have sex with your bf izuku again after that very very awkward conversation having lunch in the cafeteria you and your bf izuku and the dekusquad hung out with in class.

 After school you snuggled with your bf in longue area with the dekusquad while you could see in the corner of your eyes your twin brother Katsuki was glaring from a distance at your bf izuku with the bakusquad your only thought was that he heard that you and your bf did it at the Christmas.
