A/n: Terushima's parents are rich in this story lmaooo all those crazy parties aren't free ya know

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

"Here, try this on!"

You grumbled as your friend shoved a bikini into your arms with a bright smile on her face. You hated shopping for bikinis more than anything since you were so shy.

"Stop being like that, (f/n)! You have an amazing body and I expect you to show it off. Especially at this party tonight!" your friend goaded as she pushed you through the store and into a nearby changing room.

"So forceful..." you murmured under your breath as you held up the bikini and looked at it. There was no saying no to your friend in this situation so you reluctantly changed into it despite your discomfort.

It was the summer break before your last year of college and your best (guy) friend, Terushima, had invited you to a pool party at a vacation house that his parents owned. You usually stayed away from parties in general since you didn't like loud and crowded places, but you could make an exception for Terushima. Even though you two talked almost everyday, you hadn't seen him for a while. And you had a huge crush on the crazy party animal. How? You weren't entirely sure.

Upon telling your friend about Terushima's party, she freaked out and rushed you over to the store after looking through your wardrobe and deciding that your swimsuits weren't cute enough. Now, here you were, in a dressing room for the umpteenth time trying on yet another bikini.

"Hmm..." you murmured as you examined yourself in the mirror. You hated to admit it, but this bikini looked pretty good on you. (I'll let you imagine what it looks like okay). You showed your friend and she approved, so you paid for it and took it home, feeling nervous excitement about the party.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Later that night, you slipped on your brand new bikini, as well as a pair of shorts and a shirt to cover yourself up until you got to the vacation house. You grabbed your purse and your car keys before hopping into your car and driving to the party.

You knew the way to that vacation house by heart. You and Terushima used to spend time there all the time during breaks from school when you were younger. As the two of you got older, however, more people were invited to your hangouts over there, and Terushima began using it simply for parties rather than for spending time with only you and sightseeing.

When you arrived, you found a place to park on the street. There were quite a lot of cars parked nearby the house or inside its gates so you knew that this party was going to be pretty huge. They seemed to get bigger each year as Terushima's list of contacts expanded. You were never forgotten, though.

You took a deep breath, trying to calm your racing heart as you walked into the house. There was loud music playing that hurt your ears and made your head throb with the bass, but you tried your best to ignore it as you moved through crowds of people who were dancing, drinking, or laughing and talking loudly, trying to find the host.

"Hey! (F/n)'s here!" you heard a familiar voice call to you as you walked outside toward the pool. You turned to see Terushima in all of his half-naked glory running towards you in a pair of boarding shorts that matched the color of his old high school volleyball jersey.

Damn, those workouts really paid off, you thought as you glanced at his muscles. You then looked up into his excited, brown eyes as a grin broke out across his face. How does he always look so cute?

"What do you think of my mixtape?" he asked, wiggling his eyebrows as he nodded his head with the beat of the music that was playing in the background. "It's straight fire, right?"

"Ah, that must be why my ears feel like they're bleeding," you responded with a devilish smirk.

"Damn, aren't you as savage as ever!" he responded and punched your shoulder lightly. He stuck his tongue out at you, showing off the shiny piercing on it, and you giggled at his everlasting childishness. "Anyway, there's a strict dress code at this party, so I'm going to have to ask you to remove your clothes or risk getting kicked out." He smirked at you as he looked down at the clothing you were wearing and waited for you to take it off.

Usually, you would argue and try to remain as modestly dressed as possible, but a sudden burst of confidence made you refrain from backing down. You wordlessly took off your clothes, revealing your bikini, and watched him, placing your hands on your hips.

"Is this better?" you asked. You had no idea where all of this confidence was coming from. It was kind of weird... but you couldn't deny that you liked it. Maybe it was the bikini...?

You could've sworn you noticed that his face seemed a bit redder than before, and you smiled deviously. "Ayyee, are you a parking ticket because you've got fine written all over you!"

Now it was your turn to blush. Terushima was so unpredictable, especially with that flirtatious attitude of his. "Shut up, Yuuji..." you muttered as you put your clothes into your purse and set it down in a safe place where you wouldn't forget it.

"Come on, let me introduce you to my squad!" he told you, grabbing your arm as he led you over to a table where a group of other people were sitting. This party was definitely going to be a lot more interesting that you originally thought it would be.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

During the party, you ended up talking to a variety of different people since Terushima was cruising around and jumping in and out of different conversations. He was quite the popular guy compared to you—the usually quiet and reserved one. You couldn't help but notice that he was hanging out with quite a few groups of girls dressed in scanty bikinis, and it made you feel undeniably jealous. Especially since those girls would watch you with judgmental gazes when you walked near them.

When you weren't conversing, you were watching people play around in the pool, including Terushima, and trying to avoid getting wet when the guys had a competition to see who could make the biggest splash. You also hung around the jacuzzi, sticking your feet in to stay warm, but you only did that when you were desperate since that was where people liked to make out it seemed.

Terushima would appear next to you at the most random times, giving you a pretty face to look at and delivering one of his many pick up lines when he got the chance.

"I hope you know CPR because you take my breath away!" he told you as he put his hands over his chest.

"I don't know CPR but I know the Heimlich maneuver," you responded flatly.

The unattractive idea of that maneuver was enough to shut him up that time, but he was pretty persistent. The next time he came to visit you where you sat by the side of the pool, sipping on some soda, he said, "Did you get sunburned, or are you always this hot?"

"It's nighttime."

And he was shut down once again.

A favorite thing of his to do seemed to be to run over to you when he was soaked from being in the pool and give you a hug.

"Yuuji!" you squeaked when he appeared behind you and wrapped his arms around you, pulling into a soaking wet hug. Even though you hated getting wet, you weren't going to try to resist. A hug was a hug and you appreciated it all the same, especially when his body felt so nice against yours.

After teasing you for a few more minutes, he would leave you alone to go and talk to his other friends. You were surprised at how you'd managed to stay so calm despite all of his obvious attempts to make you flustered. It must've been the bikini.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

As the night wore on, more and more people started to leave. You wandered around the pool aimlessly, wondering if you should stay or go as you watched Terushima say his goodbyes to his guests. You wanted to stay with him a bit longer so that you could spend some time together just like the two of you used to when you were younger, so you decided to walk around and pick up trash as an excuse.

When all of the guests had left the party, Terushima returned to the pool and noticed you collecting trash that people had left behind.

"What are you doing? You can't expect to clean this place up all by yourself," he stated and put his hands on his hips.

"You're right. I can't do this all by myself since I'm not strong enough to throw you into the trash can," you responded with a smirk as you bent down to pick up an empty cup.

"Oh, you!" Terushima reached down towards you and picked you up, slinging you over his shoulder before leaping into the pool. You squealed and covered your nose as your body hit the water and you were submerged in it.

When you resurfaced, you held onto him as he moved through the water, taking you off his shoulder to push you back against one of the walls of the pool where there was a ladder out. You sat on one of the steps, watching him as he cornered you.

"I love you so much, but you only seem to love teasing me, so this is what you get," he explained as he moved his face closer to you and looked into your (e/c) eyes. His hot breath tickled your skin and made you shudder slightly.

"But the only reason why I tease you so much is because I love you too," you said, your breaths coming faster as your heart thumped loudly in your chest.

He pressed his lips against yours and kissed you passionately. The kiss felt so natural, like it was meant to happen, and you seemed to skip straight past the awkwardness of breaking through the friend zone. You two flirted so much with each other that it was like you were a couple already.

"You know," he purred when he pulled away from you, "there's a sale in my bedroom and clothes are 100% off. Swimwear included."

"That was terrible, Yuuji," you mumbled, rolling your eyes.

"But you still want to go, don't you, (f/n)?"

"Yes."

As he picked you up and carried you out of the pool and upstairs to his room, you thought about how you'd managed to be anywhere near daring enough to get yourself into this situation. You swore that it was the bikini that was giving you all of this self-assurance, but your confidence remained even after that had been taken off.
