Quinn was rummaging through her locker during first passing period when Santana walked up to her.

"Hey, Q." She greeted as she casually leaned against the locker next to Quinn's.

"Hi, San." Quinn replied with a small smile.

"I saw Finn a few minutes ago." Santana began with a smirk. "I noticed that he had one more bruise than he did on Friday."

"And..?"

Santana rolled her eyes. "Did you two seal the deal?"

After closing her locker, Quinn turned toward her with a defensive look on her face. "Why do you care?"

She cocked an eyebrow at her. "We're best friends, Q. I was just wondering. Relax."

'I need to stop being paranoid.' Quinn thought to herself. Sighing, she said, "I'm sorry. To answer your question, we almost did, but no."

For some odd reason, Santana felt a little relieved. "Define almost."

Quinn rubbed the side of her neck and looked to the side. "As in we were close and then my mom came home."

Santana laughed lightly. "Typical. But I thought now you were all for waiting until marriage or something?"

Quinn moved her gaze back to hers. "It's different with Finn. You know that."

"Yeah… but how?"

A soft smile graced her features. "Every time I'm with him, it's like the world stops and it's only the two of us. It sounds cheesy, but it's the only way I know how to describe it. The last two times we were together didn't work out because we weren't ready. But now… Now I think that we finally got the timing right. I really believe that he's the one."

Hearing her say those things caused Santana to have, strangely, mixed emotions. Of course she was happy for her, but there was also another feeling that she couldn't quite name…

Planting a smile on her face and pushing her conflicted thoughts to the back of her mind, she said, "That's great. I'm really happy for you." Not being able to help herself, she added with a smirk, "Did you want any pointers?"

Quinn knitted her eyebrows together. "About what?"

"School." she retorted sarcastically. "I'm talking about sex, Q. I happen to be an expert on the subject."

A suspicious look came across Quinn's face. "No."

"Are you sure? I could tell you what to expect."

She shot her a glare. "Incase you've forgotten, I've already done it once before. I don't need you to tell me what to expect."

An innocent smile graced Santana's features as she said, in a very bitch-like manner, "I was talking about with Finn."

Quinn stared at the Latina in astonishment. 'Why the hell would she bring that up? That's not something you remind your best friend of- taking her boyfriend's virginity. She doesn't even like Finn! All she does is make fun of him… That couldn't have changed, could it?'

Regaining her voice, she replied icily, "No. I don't need any advice from you."

Just then, the bell rang.

"Okay." Santana replied with a shrug. She then added cheerfully, "I'll see you later!"

Quinn simply stared at her as she sauntered down the hallway. She couldn't believe this. Just when she and Finn had finally gotten back together and things were right, there was another possible threat looming. And it wasn't even Rachel Berry. Nope, now she had a nagging suspicion that her best friend was going to go after her boyfriend. No, Finn was so much more than that… She couldn't lose him.

While she walked to her next class, she silently prayed that she was only being paranoid.

Finn hummed to himself merrily as he walked into the choir room. The past weekend had been amazing. Apart from quite a few heated make-out sessions he had with Quinn, they had actually practiced a duet together. Singing with her caused him to feel something he had never felt before. He didn't exactly know how to describe it, but it was a type of intimacy that made him feel extremely warm and a little mushy on the inside. Whatever it was, it made him happy.

When he spotted Quinn sitting in the back row of the corner of the room, he instantly beamed and made his way toward her.

Quinn looked up and smiled at him when he was a few steps away from her.

"Hey." They said in unison, which resulted in a fit of laughter.

Finn took a seat beside her and leaned over to give her a soft kiss.

When they broke apart, Quinn reached her hand out and gently brushed her fingers against his bruised cheek.

He flinched, but only slightly.

"Feeling any better than yesterday?" she wondered worriedly.

"A little." he admitted before flashing her a goofy grin. "But I think a kiss would make me feel much better." He emphasized his point by tapping his cheek, which caused him to wince once more.

She giggled. 'He's so adorable.' she thought with a smile. Slowly, she leaned in and placed a gentle kiss on his cheek.

When she had pulled away enough, Finn pressed his lips to hers. He broke away a little to murmur, "See, I'm feeling better already."

She got out a small giggle before he captured her lips once more.

"Hey, there are about thirty open classrooms for you two to occupy." Puck said loudly, a smirk on his face.

Finn and Quinn immediately broke apart and glared at him.

He chuckled. "It's nice to see you too."

Finn was about to make a smart-ass remark when Mr. Schuester entered the room.

"Go take a seat, Noah." Finn said in a mocking tone.

Puck scoffed but took a seat next to Mike anyway.

"Hello everyone." Mr. Schue greeted. "I was thinking that today could be a free day. You've all worked so hard this year, and I figured that you deserved some time to kick back. With that said, would anyone like to perform?"

Finn looked over at Quinn. She met his gaze and nodded.

Grinning, he raised his hand.

"Another solo, Finn?" Mr. Schue questioned.

Finn smiled. "Nope. Quinn and I have been working on something over the weekend."

"Working on something?" Puck echoed with another smirk. "Where exactly? The bed, the table, or on the desk?"

While the other members started to cackle, Quinn looked down at the ground in attempt to hide her blush, and Finn glowered at Puck.

"Settle down!" Mr. Schue shouted sternly.

Once the laughter died down, he said, "Alright, Quinn and Finn, go ahead."

When they stood up, Finn glanced at Puck. "Dude, I'm using your guitar."

Puck instantly frowned. "Why? You suck."

"I'm not that bad." Finn retorted defensively. "Besides, you owe me for that little outburst."

"Fine. But you better not mess it up." Puck said threateningly.

'How can I mess up a guitar?' Finn wondered, confused. Shrugging, he picked up Puck's guitar, quickly told the band their song choice, and then stood next to Quinn.

Normally, he would never play guitar, but that's the thing with Quinn; he did things he didn't normally do. He didn't mind at all though. Every little thing they did together that was foreign to him made it all the more special because he was experiencing it with her.

Snapping out of his thoughts, he looked over at Quinn and smiled at her. When she smiled back, he took a deep breath and began to play the introduction on the guitar while the band played the back-ups. He then began to sing.

"I remember what you wore on the first day

You came into my life and I thought, hey

You know, this could be something

'Cause everything you do and words you say

You know that it all takes my breath away

And now I'm left with nothing"

Quinn joined him on the chorus.

"So maybe it's true that I can't live without you

And maybe two is better than one

But there's so much time to figure out the rest of my life

And you've already got me coming undone

And I'm thinking two is better than one"

She sang the next line by herself.

"I remember every look upon your face"

He winked at her as he sang the next part.

"The way you roll your eyes, the way you taste

You make it hard for breathing"

She walked up to him and smiled as she rested her hand on his arm before she began to sing.

"'Cause when I close my eyes and drift away

I think of you and everything's okay

I'm finally now believing"

Finn joined her.

"Then maybe it's true that I can't live without you

And maybe two is better than one

But there's so much time to figure out the rest of my life

And you've already got me coming undone

And I'm thinking two is better than one"

Finn set the guitar down and grabbed hold of one of her hands while gently placing his other hand on her cheek. He smiled at her as he sang the next few lines.

"I remember what you wore on the first day

You came into my life and I thought, hey…"

For the last part of the song, they gazed into each other's eyes as they sang.

"Maybe it's true that I can't live without you

Maybe two is better than one

But there's so much time to figure out the rest of my life

And you've already got me coming undone

And I'm thinking, ooh, I can't live without you

'Cause, baby, two is better than one

There's so much time to figure out the rest of my life

But I figured out with all that's said and done

Two is better than one

Two is better than one"

When the song was over, Finn leaned down and gave her a slow, tender kiss before pulling her into a hug.

"Wow, awesome job you two!" Mr. Schue praised as he walked toward the middle of the room. "Your voices go really well together."

Quinn leaned back to look at Finn with a playful smirk on her face. "Yeah, I think they do too, Mr. Schuester."

Finn chuckled softly before pulling her toward their seats.

While Kurt got up to sing a song, Quinn leaned over and whispered, "You know, you should play the guitar more often."

He looked over at her with a raised eyebrow. "Let me guess, you think it makes me look hotter than I already am."

"Duh." She said with a playful bump to his shoulder. "It's also really adorable."

He made a face. "Adorable? Is that your way of saying that I suck?"

She laughed softly. "No, jerk, I'm saying that I like it. And you're actually pretty good."

"But my dancing is better than my guitar skills, right?"

Quinn pretended to think about it before saying, "No."

"Gee, thanks for softening the blow. I think I'm going to cry now." he joked as he placed his head in his hands.

"Finn, your dancing is cute." she stated with a teasing smile.

"Cute?" he inquired as he snapped his head up and met her gaze. "So, I'm adorable and cute. I didn't know that I was a freaking teddy bear."

"You're definitely not a teddy bear." she replied playfully.

"Why not?" he pouted.

She giggled a little before whispering into his ear, "Because what I want to do to you is definitely something you don't do to a teddy bear." She then placed a light kiss on his neck- right over the mark she had left three days ago.

His breath caught in his throat and his eyes widened a little. God, she always knew how to turn him on. "Tease." he muttered as he closed his eyes and began envisioning the mailman, not wanting to get overwhelmed in front of everybody.

Quinn smirked. She loved how she could have this effect on him.

Letting her gaze wander briefly, she noticed that Santana was eyeing her and Finn. 'Or was she just looking at Finn..?'

She was becoming annoyed. Santana had practically every guy in the school; why couldn't she leave Finn alone? Better yet, why couldn't she just be happy for her "best friend?"

Irritated, Quinn shot Santana a quick, menacing look before pulling Finn's face to hers and giving him a hard kiss. She didn't even care that they were in the choir room with all of the other Glee members sitting around them. All she cared about was sending Santana a message. That message read a little along the lines of "Back the fuck off, he's with me." She couldn't help it; she didn't want to risk losing him to someone like Santana- someone who would only use him then toss him aside. Hell, it sounded a little possessive, but she borderline didn't want to lose Finn. Not again. 'Uhg, I need to stop thinking like this. I trust Finn. He loves me… he would never fall for San's devious plans.' She hated how she didn't completely believe her thoughts.

"Quinn." He murmured against her lips after about five seconds.

She reluctantly pulled back and looked at him with an arched eyebrow.

Finn gave her a sheepish smile. "I, uh, love the enthusiasm, like really love it, but I can't do this right now. Not in a room full of people because, uh, I'm kind of getting… excited…" he trailed off, embarrassed.

Biting her lip to hold her laughter, she gave him a small nod and settled herself into the chair.

As Finn focused on cooling off, he couldn't help but think about what caused Quinn's sudden… intensity. Obviously he loved it- it caused him to feel highly worked up- but showing that kind of passion in public wasn't very Quinn-like.

While he thought about possible reasons for her unexpected actions, he lazily swept his gaze around the room. Currently, Mercedes was singing a song that fit her diva personality perfectly. He felt a little bad that he hadn't watched Kurt's performance; he wasn't even aware of how absorbed he had been with Quinn. Confusion swept over his features when he noticed that Puck was now sitting next to Rachel. Fairly close too. He simply shrugged and moved his eyes toward the end of the front row. There, he saw Santana looking at him. When he met her gaze, he gave her a smile and a small wave. Usually, that would be a stupid thing to do, but after all that she helped him with, he figured that they were some-what friends now.

Santana returned the smile, and Finn could've sworn it looked somewhat flirtatious, but quickly shook off the thought. This was Santana Lopez- the girl who just loved to make fun of him.

Feeling slightly uncomfortable, he swept his gaze back to Quinn. He chuckled a little at how poised and collected she was acting when only minutes ago she had been anything but that. Pretending to yawn, he slowly stretched his left arm and draped it across her shoulders.

Quinn glanced at him and saw that he had a cheeky smile planted on his face. She rolled her eyes but scooted over a bit and rested her head on his shoulder.

A mischievous glint came into Finn's eyes as a thought crossed his mind. 'Maybe I should give her a little payback for her teasing me…'

He removed his arm from her shoulders and brought his hand down to her bare knee, as she was wearing a dress. She shot him a confused look from the corner of her eye. He smirked a little before subtly moving his hand higher under the fabric of her dress, keeping his eyes on the whiteboard at the front of the room. He heard her gasp when his hand came in contact with her inner thigh. This was obviously taking a huge risk; she hadn't exactly allowed him to explore this part of her. Slowly, he began to draw small circles across her smooth skin with the rough texture of his finger.

'Oh my God…' she thought to herself in ecstasy as she bit down hard on her lip to keep from moaning. She stole another glance at him and noticed that he had a smirk on his face and his eyes on the front of the room. 'Sneaky bastard…'

Satisfied with himself, Finn took an even bigger risk and lightly brushed his finger across the lace of her panties before moving his hand back to her knee and looking over at her with a devilish smirk.

Quinn had to practically draw blood in order to stay quiet when his finger came within such close proximity to her most private part. Catching her breath, she moved her gaze over to him and met his. She immediately glared at him, though there was a hint of lust in her eyes.

He leaned over and whispered in her ear, "Payback's a bitch, huh?"

"I'm going to get you back." She promised in a whisper slightly tinged with seduction before giving him a light kiss and resting her head on his shoulder again.

Finn felt a shiver of anticipation pass through his body. Whatever she did, he had a feeling that he was going to like it. A lot. But knowing her, she was definitely going to make it hell for him to enjoy it.

The corners of his lips turned up into a lazy smile as he placed his arm around her shoulders once more.

Song: Two Is Better Than One - Boys Like Girls ft. Taylor Swift; I know that a lot of people say that this song is about a break up, but I don't know. I've always thought it was more of a love song. Either way, it's a great song! Oh, and sorry if the writing in between the lyrics is random or blehg, it's kind of hard to write duets. Anyway, I hope you enjoyed it! Leave a review and let me know what you think! Or if there's anything you'd like to see. I could probably incorporate it somehow. Thanks for reading!
