Finn and Puck moved in with each other two months after graduation. Mainly because Rachel convinced Finn to follow him to New York but Kurt didn't want him to live with him (he said he didn't want to hear them having sex) and Puck was moving to New York himself and they thought it would be a good idea.
And then somehow Santana convinced them to let her move in with them. Rachel was opposed to it, not trusting Santana but she promised to not try to hit on Finn.
Everyone got along in the situation at first. Puck and Santana were pretty much dating each other. Rachel and Finn would get the apartment to themselves whenever they wanted to fool around and Kurt didn't have to see any of their hook ups.
But after about six months, things started to go south. Santana wanted a more committed relationship, Kurt was sick of the long distant phone calls to Blaine and was thinking about giving up NYADA to go back to Lima to be with him and Puck seemed to be trying to get with Rachel.
He denied it though. But Finn could hear Santana yelling at him about how he's always checking her out and how she's even heard him say Rachel's name in his sleep. Finn doesn't trust Puck alone with Rachel anymore because of that and he's starting to feel Rachel pull away from him now.
At first Finn thought it was just her trying to be a good, supportive friend. She made sure everyone went to all of the little gigs Puck got at local bars and coffee houses. And he always returned the favor by going to all her shows for school.
Then all of a sudden Rachel was taking Puck to the opening night after parties instead of Finn. She said it was because it was more his scene, given the fact that he's a musician. But Finn just didn't trust it. And Santana says she can read people well and that Rachel will cheat on him in no time.
Finn ignored her warning, not wanting to believe that.
One night, Puck comes home late, drunk. He and Rachel had been at some party together with some of her singing buddies. Finn is sitting on the couch, trying to finish up his homework at the last minute and Santana is already in bed asleep.
He noticed the goofy grin on his face but he just assumed it was because he was drunk. He heard Puck open and close his bedroom door and within a minute, he heard Santana moaning. Finn hated when they had late night sex, they were always louder because they seemed to forget that he was here.
But suddenly he heard Puck screaming. Finn shot up, making his books drop onto the ground with a loud thud. He ran to the door, thinking something really bad happened.
"What the fuck is wrong with you?" He heard Puck scream.
"Your fucking dick is wet and you just took your damn pants off. Who the fuck did you have sex with?"
Finn's eyes went wide and he was about to leave but he just couldn't move from his spot. He heard Puck say no one and then Santana accuse him of lying.
"You're a crazy bitch. I didn't fuck anyone."
"I can practically smell the slut's cunt on you."
"Shut up." He heard Puck scream, and then something crashing to the ground. "Who I fuck in none of your business, Santana. And she's not a slut. If anyone is, it's you."
Finn could hear the sound of her hand making contact with his face. He began to rub his own face, remembering how hard Santana can slap.
He heard some more cussing and objects being thrown around. And finally he heard Santana crying and Puck trying to get her to stop.
"You fucked Rachel, didn't you?" He heard Santana sob. Puck didn't say anything but he heard Santana say, "Why does everyone always want her? What's wrong with me?"
Once again Puck didn't answer and Finn was finally able to tear himself away from the spot in front of the door. Only because he was in such a rage that he went over to Kurt and Rachel's apartment.
When he got there, Rachel was asleep, Kurt wasn't and he told him she came home super drunk and singing loudly. He woke Rachel up and confronted her the second her eyes were opened. He needed to know and she was horrible at lying to him.
The look on her face, the heart break, the betrayal, he didn't even need her to say anything.
"How could you do this to Santana and me? I know you two aren't that close but fuck, Rachel…you know how she felt about him. And me…I thought you loved me. I followed you to New York. I left my mom and my dad; I left the life I could have had. And I did it for you and you cheat on me with Puck?"
She was crying now. "I'm sorry, Finn. I'm so sorry." She moved to put her arms around him but he pulled back before she could. "I love you, Finn."
"Obviously you don't." He snapped at her.
He left after that and didn't even feel bad for leaving her alone, crying in her room. She deserved it. When he got back to his apartment, Santana had her bags all packed up and was sleeping on the couch. Puck was sitting on his bed with his head in his hands, looking all depressed.
He must have seen Finn out of the corner of his eyes because he got up and ran over to him. "Finn…"
"Don't."
"Bro—"
"We're not bros." Finn snapped at him. "If we were you wouldn't have hooked up with my girlfriend."
"We got a little tipsy. I'm sorry."
"And now Santana is leaving because of you." Puck actually looked really sad, like he had been crying. Finn knew he probably felt bad about all this but he just couldn't see past this right now. "I'm going back to Lima. You and Rachel can stay in New York and be selfish together all you want."
"Fuck you, Finnessa. Like you and Rachel were going to last anyways. You were holding her back and we all knew it."
After that comment, Finn and Puck got into a fist fight. They must have been loud because Santana woke up and kicked Puck off of Finn. He stormed out and said he'd just go stay with Rachel, which made Finn try to hit him again.
"He's not worth it." Santana said, cleaning the blood off of Finn's face carefully after she's calmed him down. "Are you really going back to Lima?
"Yea, my parents are there and since Burt's in office I get to run the shop." Finn nodded toward her bags. "Where are you going?"
"Lima. My dad can get me a job at the hospital and I'm almost done with nursing school and I can just finish the training in Ohio." She rinsed out the bloody rag before going back to work on cleaning him up. "I can't believe I moved out here to be with him. I feel so stupid."
"Well, don't. I thought he changed too. I thought he was falling for you too."
"I'm sorry Rachel broke your heart."
"I'm sorry Puck's too much of an idiot to see how amazing you are."
Santana dropped the rag and leaned into him; Finn put his arms around her waist and titled his face up toward her and Santana leaned down closer to him and pressed her lips to his.
They deepened the kiss a little which forced Finn to pull away, his lip was cut and the kissing kind of hurt. She apologized and he just laughed and told her it was ok. They stayed up and talked about their plans for when they get back to Lima.
Santana suggested they get an apartment together since they're already pretty good at being roommates; Finn likes the idea and agrees to it. Since Santana is leaving in the morning, she's going to be the one to find the apartment. Finn is going to leave New York once she finds a good place.
About two weeks past and Finn and Puck haven't talked to each other. Rachel shamelessly begged Finn for forgiveness but he said he was over her and didn't want her anymore. She seemed upset for a few days but before he knew it, she was going out on dates with Puck (Kurt called him up and told him to which he told him about him and Santana planning on living with each other back in Lima).
One day, Puck decided to push Finn too far and ask him what's it like to know that all the girls he's ever loved have had him balls deep inside of them, making them scream in ways he doubts Finn has ever made them scream.
Finn almost lost it then and there but before he could launch himself at Puck, his phone rang, Santana's name popping up on the screen. He knew she would get mad if he ignored the phone call to beat Puck in the face so he answered it and walked outside, onto the little balcony.
"I found us a place." She said in an excited tone. "We'll be paying the same amount we pay now, the only thing is it's a one bedroom not a two. So, I figured I could like make the living room into my bedroom or something."
"What's the point in that? We both know we're going to end up in bed together." She laughed a little and it really brightened Finn's day up. "When can we move in?"
"Next week."
"Alright, I'll be back there in a week."
"Good." There's a little pause and he can practically see her biting on her lower lip (she always does that when she pauses before saying something else that she's not sure if she should say or not). "Finn…?"
"Yes, Santana?"
"I miss you." She sounds all nervous which Finn thinks it adorable.
"I miss you too."
"As you should. See you in a week."
He laughs a little, "Bye, San." She hangs up first and he follows, than goes back inside.
He's happy to be able to finally get out of New York, away from Puck and Rachel. He'll miss Kurt and all but he just can't be here anymore. He begins to pack up that night. He pretty much finishes too because he can hear Rachel in Puck's room, trying to pretend she's not there.
They really have no shame and he's happy to be rid of them both.
Finn has one more day before he leaves New York. He's sitting on the couch, watching some sports high lights when Puck leaves. He doesn't really know what possess him to do this but he gets up and goes into Puck's room and just begins to rub his balls over everything.
He tells himself it's not weird and the only reason he's doing it is because of Puck's comment about being balls deep in all of his girlfriends. Finn really has no shame afterwards and doesn't even regret it as he sips on his beer triumphantly when Puck comes back and begins to strum on his guitar.
Finn made extra sure that his balls touched every inch of that damn guitar too.
The next day, Finn is carrying his suitcase toward the door when Puck sees him leaving. "Where the hell are you going?" It's pretty much the first civil thing they've said to each other since the incident.
"I'm going to Lima."
"For what…a week?"
"No." Puck gives him a confused expression. "I told you I was going back to Lima. Santana and I got a place together."
Puck actually looks like he regrets sleeping with Rachel, or regrets Finn finding out about it anyways. "I thought you just said that in the heat of the moment. Dude…you can't leave. This is what we do. I steal your girl, you find a new one and we make up."
"No, this time you steal my girl, I find a much better one and we never speak again." Finn swings the door open, pulls his apartment keys off his key ring and tosses them onto the coffee table. "By the way, I got bored last night and just started putting my balls on every object in your room. One at a time."
Puck's facial expression changed from hurt, to pissed, to disgusted, to pissed again. But before he could say or do anything, Finn was already out the door and hailing a cab.
Finn couldn't wipe the smirk off his face all the way back to Lima, knowing that Puck is probably cleaning every little thing he owns right now and freaking out over touching things that has touched Finn's balls.
