Izuku's pov

Me and Ochako were best friends ever since we were kids,she is the one who protect me from bullies and cheer me up,she pull me out from being alone and having depression,I promise to myself not to betray her,until her boyfriend comes in our life..

Ochako was just dragging me towards the park happily because she told me she had a boyfriend and she wanted me to meet Him

I just giggled and let her dragged me until we arrived at the park,Ochako looks at me and her boyfriend smiling"Okay Izuku-kun! This is my boyfriend Katsuki, And Katsuki this is my best friend Izuku!"She said smiling

Both me and Katsuki looked at eachother,I smiled at him "Well hello! It's nice to Finally meet you!"I said

Katsuki just looked at me with disgusted face as I got irritated, what a snob!,I looked at Ochako "I don't think he is good for you Uraraka-san.."I said as I looked at Katsuki again and glared at him

"Oh really? Well I don't think you'd be good for her aswell"Katsuki said as he glared back at me

"E-eh? C'mon guys, quit fighting"Ochako said"Izuku, Katsuki is a really nice guy and sweet also!"She said as he turn to Katsuki"and Katsuki, Izuku is a fun guy and supportive and kind also! So why don't you guys shake hands and get along!"She said while smiling awkwardly

"...."Both me and Katsuki sigh and shakes hands while looking away from eachother

Since that day,we always fight over who will hangout with Ochako or who will walk her home,we don't clearly fight for everything, just for ochako

And Katsuki always tease and make fun of me but Ochako keep saying it was just for fun and it was a joke

I tried to keep my patience whenever he is around, especially when he is with us of with Ochako

It has been 6 months and me and Katsuki are still enemies

One day,Ochako told me that she is having a sleepover,and I was invited ofcourse but sadly, Katsuki is too

I go towards Ochako's house and knocks, Ochako opened the door and let me in,I realizes that the only people were me,Ochako and Katsuki"huh? Where are the others that you invited?"I asked

Ochako looks at me with a teasing smile"I lied, it's the only way for my best friend and my boyfriend to get along"she said as she kisses Katsuki

"..."I sighed and agree,I was kinda getting tired anyway from our fighting and teasing

Katsuki also agreed with it,it was kinda working but we fight the whole night, while we were just going to sleep on a futon,I realizes Katsuki is in the middle one

I frowns"why does he have to be in the middle one hmhp, Ochako can you be in the middle?"I looked at her

Ochako shake his head"no, I'm tired from you guys fighting so deal with it"She said and lay down,I knew her answer would be no since she completely trust me for not stealing her boyfriend

I just sighed and sadly agreed,I laid down as Katsuki laid down aswell between me and Ochako, Katsuki hugged Ochako from behind as I faces the wall trying to sleep

I manage to sleep after 1 hour or 2.

Katsuki's pov

In the middle of the night while everyone was asleep,I turned around and looked at Izuku"...."I slowly goes to him and hugs him from behind

"Hm.."I slowly starts grinding on him a bit as Izu felt someone was touching him

Izuku moves a bit but I didn't stop, instead I grind on him more while rubbing his soft, smooth thighs 

Izuku shudders and slowly wake up"h-huh?...~ the hell?...~"he said softly as he looked at me

Izuku's pov

I realizes what Katsuki was doing and quickly pushes him off "the h3ll you doing?!"
I said whispering so Ochako wouldn't wake up

Katsuki ignores me and just looked at me with a smirk face as he goes closer to me and grab my waist gently

I blushes by his gentle touch and quick snapped out of it and pushes him again"answer my question! Don't you realize what you are doing?! You are betraying my best friend! I'll tell this to her Cheater!"I said still whispering so nobody will wake up

Katsuki once again ignored me and goes ontop of me, before I could even pushes him away and say anything,he took off his shirt

I blushed and tried to push him away but I started to feel weak, his body is just so hard and big, especially his chest and abs

A feminine body like mine could never beat him! So I just slapped him real hard "Get off of me you j3rk!"I accidentally yelled

Thank god Ochako didn't woke up, she just moves a bit and hides under the blankets like she always do

I glared at Katsuki but Katsuki was looking at me with a smirk face,he took off my shirt aswell,i tried telling him stop it but he wouldn't listen "aww c'mon~ your red face tells that you want it~" he said in a flirty way

I shake my head no while hiding my face"like hell I do!"I said whispering as I continue trying pushing him off

Katsuki's pov

I undressed both of us and now we are both naked,I grabbed a blanket and wrap it around us

I started kissing Izuku's neck and biting it which made Izuku moans softly a bit, Izuku continues struggling to push me away but I won't give up so easily

I made him lay down on his stomach and while I was giving him hickeys and love bites on his nape,I started rubbing my finger on Izuku's tiny little h0le, Izuku tenses up and looks at me blushing with sweat "w-what are you doing..?"

I just smirked and slowly put my finger inside him and that made Izuku moans more a bit. I insert another finger in and starts thrusting them

"A-ah~"Izuku was trying to hold back his moan,he tried to get my fingers out of him but I won't let him

Izuku soon gave up and let me do anything I want with his body,I smirked happily and I f#cking rail€d him,I was pounding him non stop

Izuku was covering her mouth trying his best not to moan why his tears flow,Uraraka wasn't waking up and that's what we are glad about

After we finished for about 2 and a half hours, Izuku was facing the wall crying silently while hugging his knees feeling disappointed to himself
