Ladies and gentlemen here is a familiar story that has a similar premise. An OOC tsundere-(semi) yandere Katsuki and an OOC Izuku. Izuku and Katsuki are invited to Yuga's party. Katsuki gives Izuku a hard time but is fearful when Izuku grabs the attention of the girls. At that particular moment, hard time means desperate measures. What would Katsuki do at the party? Stay tuned and find out!

It was a cool Halloween night at the UA High's campus dormitory. Izuku was in his dorm as he prepared to head to the party in town that was being hosted by the so-called French prince, Yuga Aoyama. He was double-checking his appearance in the mirror. He had honestly felt that he had looked ridiculous. Most normal teens would wear something sexy, cool, or raunchy to parties. Shouto and Momo were going as Gomez and Morticia from The Addams Family. Denki and Kyoka were going as Sid of the Sex Pistols and his girlfriend, Nancy. Tsuyu was going as a youkai, Toru, ironically, a ghost of a kamikaze soldier, and Ochako was going as a sexy neko.

He dropped his head as he was about to see Ochako sporting a black leotard with a tail and a bell. She was even sporting the cat ears. He slapped his forehead as he was comparing himself to a Sailor Boy. He was sporting the outfit that was worn by the character, 9S, from the video game, NieR: Automata. As much he wanted to protest, it wasn't his decision.

As he sighed, he heard three distinctive knocks on his door.

"Open up, you baka dog! I know you in there." The discouraging, teasing remarks were coming from his childhood friend and the vain of his existence, Katsuki Bakugo. Since as long as he could remember, the blonde has been his displeasure. Since knowing each other at the apartment complex they once lived, she has given Izuku nothing but making his life a living hell.

He heard the knocks again. This time harder. "You can pretend if you are not there, baka! If I answer the phone and I hear it, then you are really going to get it!"

Izuku looked to the floor as he heard her making the countdown.

He had opened on 2.

"Well, hello, Sailor Boy!" Katsuki leaned against the door frame, snickering at her childhood friend as he was sporting the costume she had forced him to wear. The sixteen-year-old loved messing and teasing her fallible, naive pushover of a friend. She licked her lips as she couldn't wait to pull out her cell phone to take pictures.

Katsuki entered the dorm, closing it loudly. The teen didn't know anything about personal space as she went, without permission, to his refrigerator. And of course, she drank his last iced tea. She purposely watched Izuku's annoyance while taking a seat on his bed.

Izuku looked in the mirror as she, too, was sporting her costume. She had decided that she was going as 2B from the video game, NieR: Automata. Since the game's release, the blonde couldn't get enough. Hours were spent at Izuku's dorm. Using his server, his PSN money, and his time, she played the game while making him watch.

She patted his bed as she continued to drink his canned tea. "You would think your father could afford a bit extra for some mattress padding. Poor salaryman baka!"

Izuku scoffed under his breath. He knew better if Katsuki were to see him do it.

For there were consequences.

"So, you are ready to go," asked Katsuki while she glared at Izuku's costume. She was certain to make sure his clothes were to his discomfort and a size smaller. One thing for this tsundere, she loved seeing his assets in those shorts. Of course, she wasn't going to let him know of her true feelings. There was no way she was going to let him know that the teasing and the bullying were to hide her true feelings for the emerald blockheaded baka.

"Sure," answered Izuku as he looked at himself in the mirror. He wanted to be certain to remember his face before being humiliated in front of the student body.

Katsuki reached into her pocket and tossed him his blindfold.

"Thanks," he said reluctantly.

"Who said I did this for you," scoffed Katsuki as she put on her blindfold. "Just helping others from seeing the ugly."

"With your ugly ass attitude and people think we go together, I don't blame you," he said under his breath as he sported the blindfold.

Suddenly, he saw an approaching shadow behind Izuku. Katsuki narrowed her eyes, releasing her smile. The kind of smile that shows anger and the bulging vein on her forehead. "What was that, you dog? Shall you repeat what you have said to my face?"

Nervously, he recanted. "It was nothing, Kacchan! Nothing at all."

She relaxed her face. "Good!"

She hit him anyway!

"Ouch!"

"Shut up, you baka! Let's go!"

About an hour later….

Izuku and Katsuki were en route to Yuga's party. They have boarded the train. The emerald-haired teen kept his earphones on to avoid the obvious laughter from the nearby passengers. It was one thing of looking like a Sailor Boy. It was another thing that his shorts made as well been underwear and he couldn't get his shirt lower than his belly button. Flushed and flustered by his getup, he prepared to spend the evening at the party in the bathroom. That way, Katsuki wouldn't find him.

Thirty Seconds to Mars was his savior for the moment as he prepared himself for the embarrassment.

Katsuki pulled his earphone from him. "Are you listening to me, you baka!" She flicked his forehead. "Don't tell me that your clothes are cutting off circulation from your brain as well?

'Fuck off, Kacchan!"

She punched his shoulder.

"Ouch! What was that for," cried Izuku.

"I know you, you putz!" She flicked his forehead again. "And fuck you very much, Icchan!" She flicked him on his forehead again.

"Ouch!"

Izuku looked away while rubbing his aching shoulder. Katsuki turned to look to her cell phone. She glanced at Izuku as she observed him. Oh, my God, Icchan! I am sorry, okay? Sorry for not being honest with my feelings. You weren't paying attention to me and that worried me. You didn't even once complement my costume. Katsuki saved her allowance for a month to purchase the costumes. The costumes weren't cheap and it was worth every single cent. She even purchased special lingerie to accompany her outfit with the hopes that she can have her way with Izuku tonight. However, she knew that this was going to be a cause of concern. I bet if I was the big breasted bimbo, Yaoyorozu, then you would have noticed. If I were Ashido, you would have noticed. If I was that plastic, cheap, nerve-wracking, goody-two-shoes, dumb bitch Ochako, you would have definitely would have noticed. The thought of Ochako angered her the most as her acute hearing depicted what Izuku said under his breath. Sorry that I am not some damn goody-good. I can't help how I am. That is how I show my love, you baka! You make me feel wonderful things. Wonderful things I am afraid I can no longer contain!

She bit her lip as she felt something beyond her womanhood trembling. It was called her second blessing and it came free of charge. Go down! Go down! Please go down! I don't need him to know! Not yet! Not yet! She thought of things to calm her erection. Such as shoving it inside of Ochako's throat.

That alone made her feel better.

She kept quiet as she snatched the earphone and proceeded to listen to his music. Knowing that his follicles were within her hair was alluring. Admittedly, she wanted him to be her boyfriend. Ever since they have known each other since the sandbox days, she had deterred him from doing anything that seemed achievable. It wasn't just because of her competitive nature, she felt that was the only way to keep Izuku in her life. She knew it was wrong and it was selfish but if that was the only way, may God forgive her.

To be continued….Yes, I know that is a short chapter. I felt it needed a little buildup before the next chapter. Stay tuned! I hope you enjoyed!
