Bkdk Omegaverse based on the movie Love Potion No. 9

Where Izuku and Kaminari are two hopeless omegas unlucky at love, their dates mostly on negative numbers and their dreams of a mate and family almost crushed. When they see an ad about some magical potion, they have to try.

They call "Madame Cammie" about the add, and she tells them that for the potion to be effective she'll need two drops of their slick. Which offended Izuku and gave him a bad feeling, but after so much pushing from Denki he agreed.
"We can't stay single forever Zuku... pleaseeee"

So with a lot of determination, doubts a bit of hope, they take their samples to Madame Cammie.
She takes them and with each same she produces a perfume.
"You need to use two drops per day babes, more and you'll drive the Alpha crazy" the both nodded, gulping.
"How....it works?"

"Just apply the two drops next to your scent gland, close to the Alpha of interest, and they'll be all over you"
"Can't wait to try this my boss" Denki blushes as he takes the bottle eager for its magic to appear.
"I hope it's not a scam" mumbles Izuku, taking out his wallet.

"But remember" says the Madame looking somber "this potion stimulates the subject by voice, just by saying their name... so be careful or you'll have Alpha brawls all over"
"Sure" says Izuku snorting. Alphas fighting over him... yeah, right. As if.
Denki just grins, too excited.

Next day Denki gets ready for work, applies two drops of the parfume to his neck and struts over to the gym were he teaches aerobics.
He changes into his tightest leggings and goes over to say hi to his boss, Kirishima. As quick as the "Hey" goes out of his lips, the Alpha

is already looking at him funny...and blushing?
"Hi...hi.. De.. Denki. You look pretty today, not that you don't look pretty everyday, just today, you wow" the redhead mumbles as Denki pinches himself.
"I have.. to.. go and work?" he says walking and turning around slightly just

to catch Kirishima staring at his ass.?
The whole class he finds the boy staring at him, and when he's about to end his shift Kirishima ask him out for .. and they end up in bed before the night is over.
"DEKU. THIS WORKS. OMG. TTYL" he types before his neck is attacked by kisses

The next morning Denki walked into Deku's apartment with Starbucks.
"You are not going to believe what happened" he sang.
"You reek of Alpha" coughed Izuku, opening the window to let air enter.
"Well, I was with an alpha, with Kirishima... the potion works!!!"

And so Izuku spent his morning listening to his friend babbling about the incredible sex he had with that Alpha.
He was a bit jealous, at least Denki had someone he cared about, Izuku didn't.
But looking at Denki so happy, made him feel as if he atleast had to try.

Next weekend found Izuku and Denki at a dance club, apparently Kirishima had a friend to introduce them.
So there he was, Izuku in a skimpy outfit, two drops of the potion on his neck, while he nursed a drink, his friends practically having sex at the dance floor.
"Nice ass"

a raspy voice made him turn ready to tell them to fuck off, and wow, Adonis was real. Golden hair, red fiery eyes, strong arms, and a body to match.
"M.. Me?" stuttered Izuku as the guy got closer to him.
"Yeah, you. Want something to drink gorgeous?"
"I.." he nodded as the guy

circled his arm around his waist, looking at the bartender.
"Something soft, for now Hanta"
While they waited the blond took the time to look him up and down, while Izuku blushed.
"Bakugou, Katsuki"
"Uh?"
"My name, Katsuki, yours?"
"Izuku"

What started as a drink or two ends up as Izuku moaning Katsuki's name as he is pounded into against his front door.
He can't believe this is happening, that this gorgeous man is currently devouring him whole, him, plain looking Izuku.
Damn, that Madame Cammie was onto something.

They were all over each other the whole night, not a single space on their bodies unexplored.
Next morning before Katsuki left he was surprised by breakfast in bed and another round of fantastic sex. Izuku felt himself powerful, and for once he thought. "Love might be waiting for

me"
So while he searched for that someone, maybe he could spend a little time with Katsuki. They had fun, lots of, and mind blowing sex, sometimes Izuku felt bad about having the boy under this magic spell, but he was going to set him free and apologize, eventually, once he finds

the one.
"Don't you ever think of... I don't know... having a relationship?" asked him Katsuki once while watching TV.
"You wouldn't want that, believe me" chuckled Izuku.
"Why do you said that?" he asked again, confused.
"I just do. Besides this is fun right?"
"Yeah.."

But Katsuki was right, after two months of sex and domestic breakfast, movie watching and being close in general... Izuku was starting to feel, and it wasn't a great idea.
Katsuki already wanted to introduce him to some friends and Izuku kept on finding excuses. Mostly job.

And mostly job found him being introduced to his boss son Shoto Todoroki, and once they interchanged names, he knew there was something there. He couldn't pitpoint what... but he felt suddenly enamored by Shoto's eyes.
What Izuku ignored was that the Alpha recently visited Madame

Cammie too.
It all went too fast, after that, they spent the whole night talking, and Izuku felt that he couldn't separate himself from this boy.
Once he got home he was smiling and sighing like stupid, just to find Katsuki in his apartment waiting for him.
"You stood me up"

"What?" said Izuku feeling himself annoyed by the mere view of Katsuki.
"I.. Movie night, with my friends?"
"Oh that. I forgot sorry" Izuku mumbled scratching his head.
"What is wrong with you?" Katsuki was mad.
"What is wrong with YOU?" he replied bitterly "we are not a couple"

He could see a flash of hurt on Katsuki's eyes and then he was putting on his jacket.
What did Madame said about liberating someone? Oh yeah!!
"Katsuki I set you free" he said staring at the boy seriously.
"Fuck you Izuku" the other let out angrily, throwing the door.

Two week passed without Katsuki's in his life. Izuku missed him he knew that, but he had Shoto and he felt as If he couldn't live without him. Soon enough they were moving together, and had plans to marry.
Izuku was happy? But at the same time everything seemed so fast.

Preparations coming and going, Izuku being introduced to family, associates and friends, and he couldn't help but to think about Katsuki.
What was he doing?
What was he thinking?
Was it normal to think so much about someone when you were about to get married?

He knew comparing people was wrong, but he couldn't help but miss movie nights rather than go to another boring dinner. He missed breakfast in bed and Katsuki's arms around his waist at any given moment, his soft kisses, and his passionate way of loving him.
Was this normal?

"Shoto, can we cuddle an watch movies tonight?" he asked pulling his fiance hand, bringing him towards the couch.
"Why would I want to do that?"
"Because it's fun, and cuddles?"
Shoto sighed, and stood up "We have no time for that, I have a business meeting"
Izuku nodded"O.. Ok"

Instead he invited Denki over, he didn't want to feel that lonely.
"I wish love was like the movies" Izuku smiled dreamily.
"My love life is like one" Denki said, blushing a soft smile on his face.
"Maybe because you haven't stopped using the potion" mumbled Izuku bitterly.

"What are you talking about? I told Eiji about a month a go?"
"Wait.. what.. You are still together?"
Denki nodded, reaching for the popcorn.
"He was really sad about it, we had a small break, but, eventually... well, he said he loved me" giggled his friend. "I.. I do to"

And in that moment Izuku felt happy for his friend, but at the same time there was a bit of jealousy there... there was something there that his relationship lacked, but he didn't know what.
"Can I use your bathroom for a minute?"
"Denki, you don't have to ask"

"Hey Zuku, why do you have your potion in your medicine cabinet?" asked Denki when he got out it the bathroom.
"Denki, seriously what is with you and checking people's cabinets?"
Izuku laughed and then stopped abruptly "Wait what... My what?"
"The potion" said Denki bringing

said bottle "Didn't know you got the big size"
Izuku felt sick "That's.. that's not mine Denki"
"What do you mean?" asked his friend confused. "Who else would have a big bottle of, Denki read" Potion N. 6 for .. Alpha use? "he gaped.
And Izuku knew what he was living was a lie.

"Were you planning to tell me?" sobbed Izuku later confronting Todoroki.
"I... I never intended for this to... to be this long... I'm sorry" the other boy let out insecure.
"I need you to set me free" whimpered Izuku, getting closer to his fiance, as if magnetism worked on them.

"But... the wedding. What I'm supposed to tell my father?" Todoroki hugged Izuku, desesperate.
The omega growled, even thought the forge was telling him to purr at this fiance.
"SET. ME. FREE" he pushed the other away, glaring at him. "Let me go" pleading.

Todoroki nodded, kissing his cheek and whispering the words against it.
Izuku felt himself crumble and fall to the floor, his heart beating, suffocating... and his mind free of the fog of the potion brought him memories of him, only of him, of Kacchan.
Todoroki let him go and he

found himself at Kaminari's place crying about it, about his fiance, about lies and Kacchan.
"Todoroki is an asshole, and I never go to meet that Kacchan you always talk about" says Kaminari, taking out their much needed ice cream.
"I got this picture. So handsome" mumbles Izuku

giving his phone to his friend.
"UH... BAKUGOU IS YOUR KACCHAN?"
"Bakugou Katsuki" Izuku wails again "I hate that potion so much"
"BABEE CAN YOU PLEASE COME HERE FOR A MINUTE?" his friend calls Kirishima, who jogs quickly from their bedroom.
"Yes honey?" Kaminari just gives him

Izuku's phone.
"This is Kacchan's Izuku. The one of the potion story"
Kirishima looks at Izuku, at Kaminari and then at the phone. "I think there's a big misunderstanding here"
"Wh.. Why?" Izuku asks softly wiping away his tears.
"Well...I'm not Madamme Cammie, but I'm his friend

and I'm pretty sure Katsuki's been asking me to introduce him to Denki's green beauty of friend before this whole potion thing happened... "
" That means...? "Kaminari looks at his friend sadly.
" It means I really hurt Kacchan...I ruined everything"

"Oh man, I was supposed to introduce you guys at the bar a few months a go" Kirishima says crestfallen
"We met at a bar" sniffles Izuku, hugging his ice cream cup. "I... I was an asshole to him" wailed Izuku again.
"I'm sure we can fix it Zuku" the blond omega rubbed his back

And they tried to, but any mention of Izuku had Katsuki hanging up their calls, and ignoring their messages.
Katsuki was hurt.
He never wanted to fall for someone in the first place, and then he saw the green haired beauty at the gym once and went crazy.
And he fell inlove and

he thought that Izuku did too. He wanted to include the omega in his life, wanted him for more than just his body. Wanted to mate and to bond and to... wanted to live..
But Izuku, his Deku, it was just sex for him?
And then to found out he was engaged to some bratt?
It hurt

So it was a surprise to find Izuku out of his job, looking down at his shoes and holding a big bento box.
And Katsuki, fuck, he wanted to be mean and send the omega away, but then he was looking him with those green eyes of his, about to cry.
"Kac.. Kacchan.."
"Ok, let's talk"

"So let me get this straight" said Katsuki, picking food from his bento to feed Izuku, without realizing it. "You though I was with you because of a magical potion?"
Izuku nodded blushing as he took a bite of what the alpha was feeding him.
"and your fiance was doing the same?"

He nodded once more, looking at Katsuki with big fond eyes. The alpha seemed to realize what he was doing and his face turned red.
"I.. I don't know what to say... I...fuck"
"Im sorry for hurting you Kacchan
.. I really like you" Izuku said picking from his bento to feed the boy

Katsuki embarrassed took the bite, feeling his heart fly at the gesture.
"I don't know If I can forgive you" he glared at the omega.
Izuku looked down "I know that. I'll try my best. You are the only alpha I want"
And Katsuki, fool, inlove, stupid Katsuki couldn't handle it

He tried to use his pride talk for himself.
But fuck... He's been crazy inlove with this fucking omega since the first time he saw him.
"Well.. I could consider a courting period, like some test, to see how we go" trying to sound disinterested.
Izuku replied with a strong hug

A few months later

"Babe, you forgot to pack your toiletries"
"I did not Kacchan, I packed them earlier" Izuku said bringing another box.
They were finally moving to their new home. They got a cute house with enough space for them, and maybe some pups in the future.

After all they wanted their kids to be friends with the Kirishima's twins, that were about to turn two.
"And what about this Potion N. 6 parfume?" Katsuki asked scratching his head.

"Don't need it, throw it away"
"Are you sure? "
"Yup. I got all I want right here" he smiled hugging his mate.
"Ugh so corny" smirked Kacchan, hugging him harder.
"Kacchaaaan!"
