My omega

heat day 3

Izukus POV

I wake up next to kacchan, making sure to carefully get out of bed so he doesn't wake up. I go downstairs and start cooking, knowing that he will instantly want food when he wakes up and will try to make it himself cause he can't just rest due to his "training". 

After a while I finish and bring it upstairs, seeing that he is awake and groaning lightly to himself, probably not wanting to move at all from all the pain he's in.

"babe I brought you food" 

He groans and sits up and I sit next to him

"How are you feeling love?"

"like shit"

"Want me to feed you?"

"yes please" he makes puppy dog eyes at me

I smile and he opens his mouth so I feed him a spoonful of the food I cooked for him.

He smiles and starts to chew it and once he finishes he said "this is so good thank you!" He opens his mouth for more and I give it to him.

After a while, it's all gone and he's full. 

"what do you wanna do now love?"

"fuck me alpha~"

"is that what you want? Remember one time a day, this would be your one time today." I question

"yes please alpha I need you~ I need you in me please~"

"hmmm beg a little more and I'll consider it."

"please alpha! I need your knot in me! Please fuck me please pup me! I want your pups, please! I need them! You need to make me feel better!" He turns over so he's laying on his chest, pushing his ass up, which was completely naked because he has only an oversized shirt on, no pants, no underwear, and when he leaned down, it slid off, exposing his plump, round ass.

When I see it I slap it harshly on instinct, making him moan out loudly and say "please alpha~ ruin my slutty little body~ degrade me~ hit me~ spit on me~"

"aww, my little slut is so needy arent you~" I pull a condom out of my pocket, then pull my pants and boxers completely off, then slide the condom on. 

I slowly push myself into him 

"ah fuck alpha take it off~ take off the condom I don't want it~, please! I promise I won't get pregnant! Please just cum in me and stop all this! It's too much! I can't take it anymore please alpha!!" 

I felt bad but I had made a promise that I would use a condom "babe, you know that you would be mad at me if you weren't in heat."

"No! no! I promise I won't be mad!!" 

"you sure babes?"

He pushes me out of him and takes off the condom, then looks back at me with the most lust-filled eyes I've ever seen, so lust-filled that I lost all common sense and rammed into him, imminently hitting his prostate and pounding into it.

"ah! fuck! Alpha! more please!!"

"you're such a needy fucking slut!" I slap his ass

He cums from all the pleasure and hearing me degrade him for the first time "ah~ yes! Your slut~! Only your slut~! "

"Good! I'm the only one allowed to see you like this you understand you dumb omega!"

"Yes! Yes! I understand alpha!!"

I spit on him "fucking beg for my load slut!"

"Ah~ alpha! Please give me your knot! please! Pup me up!! I promise I'll take care of them!! Please give them to me!! I need it! My womb is begging for your cum!! Please! Please alpha I need it!!" 

I smirk and thrust all the way in one last time and cum deeply in him, my knot instantly inflating in him, stretching him wider.

He pants loudly as I wait for my knot to deflate and he whispers "thank you alpha~"

"You're welcome omega~"

After a few minutes, my knot deflates and I pull out "how do you feel kitten?"

"sore, but my mind is clear... wait what happened?"

katsukis pov (hehe bet you didn't expect that)

I look back at Deku, looking down and noticing his dick covered in cum, immanently realizing that he had came inside me and I gasp.

He looks down at me with shame all over his face, clearly feeling guilty though I know that my heat has been hard on him and his inner alpha probably took over, making him cum in me, I know he wouldn't do that on purpose so I say "Its okay alpha" I think a bit and remember I promised I wouldn't be mad "I told you I wouldn't be mad, and I'm not"

He smiles down at me "I promise, if you're pregnant I will help take care of our child"

"it's okay alpha, I'm your omega, you choose what to do with me"

"I love you"

"I love you too, alpha"
