There is cheating in this one. They are adults.

Part 1

-

It was 7:40 pm when Atsumu texted Oikawa. They had their usual conversation, nothing interesting. That was until Atsumu asked Oikawa to go to a party with him. Of course, Oikawa agreed, who would he be to deny?

Atsumu agreed to pick Oikawa up at 8 and they head out to the party from his house. Oikawa went upstairs of his and Iwaizumi's shared house to take a quick shower. He got dressed, brushed his teeth, and did his hair.

Oikawa started to walk downstairs, as it was time for him to leave. He grabbed his phone and keys, but before he could leave out the door he was stopped.

"Hey, Tooru, where are you going?" Oikawa turned around and was greeted with his lovely boyfriend.

"To a party with 'Tsumu."

"Oh.. Have fun, don't stay out too late. Don't drink too much either"

"Okay. Love you."

Before Iwaizumi could respond Oikawa gave him a quick kiss on the cheek and left.

Atsumu and Oikawa arrived at the party in about 10 minutes. To Atsumu's surprise there were more people than expected. It was supposed to be a small MSBY Black Jackal party, but invitations were sent and more people ended up coming.

Oikawa knew most of the people, but didn't put in much of an effort to talk to any of them.

He walked over to the food and drinks table and grabbed a cup. Oikawa poured himself a drink of what he could only assume had alcohol in it.

Oikawa walked acrossed the room and plopped down on the couch.

"Hey, what's a pretty boy like you doing at a party like this?"

"Same thing you're probably here for," Oikawa said without looking up.

"Terushima. I'm Terushima and you are?"

"Oikawa." Oikawa took a sip of his drink, finally looking up at the male next to him.

"Ah, a pretty name for a pretty face." Oikawa looked away as his face flushed red.

"So.. If we're here for the same thing, you in hopes of fucking someone? Hmm, no, you look like a bottom."

Oikawa didn't know whether or not to be offended, so he just shrugged, "Perhaps, I am here to be fucked."

"Oh?"

"Why so interest in my sex life? You must want to be apart of it." Oikawa said in a very obvious sarcastic tone.

It was quiet for a moment before Terushima took a sip of his drink and spoke again.

"So you're single?"

"Maybe, maybe not."

Terushima chuckled. It would be a lie to say Oikawa didn't pique his interest.

The two continued to talk, honestly quite interested in each other's life. Oikawa had learned a few things about Terushima. Things like, his tounge piercing was an impulse piercing but he doesn't regret it. He also found out that he's single.

By this point of their conversation, both men were drunk and clearly weren't thinking straight. Meaning they went from a simple conversation to a full blown make out on the couch.

For a moment Oikawa was hit with a spike of guilt, but why? Oikawa shook off the feeling and kissed back, he wasn't gonna let this ruin his chance to get dicked down.

Terushima pulled away drom the kiss, "Why don't we take this to one of the guest rooms?" Oikawa agreed and the two men went into an empty room.

The second the door was closed, Oikawa was pushed up against it and roughly kissed.

Let's just say... Things got dirty real fast.

The next morning

Oikawa woke up the next morning to numerous misses calls and text messages. Some of which were from Atsumu, others were from the pretty setters groupchat, and the last bit was from Iwaizumi.

Iwaizumi.

That's why Oikawa felt guilty.

He has a loving boyfriend waiting for him back home.

Goddammit! I fucked up... Again.

This wasn't the first time Oikawa had got drunk and cheated, but for some reason he felt worse. Why?

Oikawa got out of bed, only to feel a pain in his lower back. Oikawa worked through the pain, putting his clothes on. Right as Oikawa was about to leave he heard movement behind him.

"Why leave so soon? What's the rush?" Oikawa turned around forcing a smile.

"I just- I need to get home." Oikawa grabbed a random piece of paper and pen, and scribbled his number on it.

"Here, call me sometime." With that Oikawa rushed out of the house.

Oikawa got home about 30 minutes later. Oikawa prayed Iwaizumi wasn't home, he was supposed to work today, right? Boy was he wrong, Oikawa sat right infront of the door reading a book.

Iwaizumi closed the book and stood up.

"I specifically told you not to stay out too late. This is like the 4th time, this month."

"I know and I'm sorry. I just got drunk and passed out on the couch." Oikawa half lied. He was drunk, not passed out on the couch though.

"Oikawa.. I think we should take a break. I- We- ...It's just my mental health isn't in the best place right now and- and are you cheating on me?"

"I- what?" Oikawa was taken aback, it was random, but not an unexpected question.

"Are you cheating on me? Is that why you stay so late at parties? I know Atsumu goes home at the end of the night, so you would have no other reason to stay after..."

"I- I don't want to answer that..."

Iwaizumi let out a pained laugh and walked back to their shared room. After a few minutes he walked back out with a small suitcase.

"I'll be back in a few days, I need to clear my head." Iwaizumi left without another word.

He left...
Oikawa's partner of 7 years left...

I've really fucked up this time, huh?

Oikawa sat down on the couch, receiving a text shortly after

Hey, it's Terushima.

Great, just my luck.
