A/N: hello amigos! I know I promised this story ages ago, but it's finally here! Yay!

If you're new to this story, I would advise you go check out But Now What first, to clear up some things that may be related to in later chapters.

Anyway, I hope you enjoy Summer Lovin' and don't forget to review and all that jazz!

[LINE BREAK]

"Did you do this?" Beca grinned at her boyfriend, Jesse, as she noticed juice pouches tucked into her suitcase that she definitely hadn't put there.

"I did no such thing," he winked back at the Bella from his spot perched on her now bare mattress.

"You know I didn't invite you over here to supervise," she raised an eyebrow and tossed a pillow at him.

"Well maybe next time you should consider packing before the morning we leave," he offered, easily dodging the poorly thrown pillow.

The pair was putting off having to go their separate ways as long as possible. They both had quite the drive ahead of them, but that was the least of their worries when they knew they wouldn't be seeing each other for at least a month and a half. It had been arranged that Jesse would drive out and stay with Beca, her mom, and her mom's relatively new husband Austin for a week, and then the two would head out to the lake that was a couple hours away for some time alone. "Do we have to leave?" Beca mumbled, moving to sit with the Treble on her bed.

"Unfortunately," he sighed, wrapping an arm around her and pressing a kiss to her temple.

"Beca? You almost ready?" Professor Mitchell's voice came through the door, two knocks following.

"Not at all," she called back, not bothering to let her dad in.

"Get a move on, everyone's out of here by noon, and your mom is going to be waiting for you to get home."

"I'll be ready, chill out," she rolled her eyes, although he couldn't see, leaning back into her boyfriend. He was grinning at her. "What?" She frowned.

"Nothing," he shook his head. "I'm just going to miss you a hell of a lot."

"I'm going to miss you, too, Nerd. C'mon, help me finish packing or I'm kicking you out." Of course she really didn't want to finish packing, but she knew if she dwelled on the fact that she was going to miss him, she'd probably cry, and crying wasn't something she was feeling like doing. It was supposed to be a happy day, like 'woohoo, we survived our second year of university,' but really she was dreading it.

She hadn't landed the internship she wanted, which meant she had gotten stuck with some shitty waitressing job at a restaurant ten minutes from her house called The Grill.

Jesse was with his family most of the summer, going camping and doing other family-like things.

About an hour and a half later, they'd managed to mostly finish packing. "Come on," Jesse grinned at Beca, taking her hand and dragging her into the hallway. "We have one last performance to do." The Trebles were performing for the new kids who were interested in coming to Barden next year. The Bellas had been offered, but decided to let the Trebles have one thing going for them, so Beca was tagging along to watch.

She took a seat in the middle of the theatre, kicking her feet up on the chair in front of her. There was a overly peppy blonde on the stage, explaining the pros of attending Barden, and the BU Knight was frolicking across the stage. "Alright, and for the close, we have a performance from the Barden University TrebleMakers!" The crowd cheered as Jesse and the guys came on stage, clad in their burgundy jackets, and Beca smiled to herself.

"Hey, we're the TrebleMakers, and this is Make Out." She laughed at the song choice, drawing her bottom lip into her mouth.

If I could live forever then

I don't know what I'd do

I forgot just what I meant to say

But I'm still in love with you

He was singing right to her. She caught his eye and he winked back at her.

I don't even know your name

I don't even know your number

But I know I need you right now

Living in a crazy world

You make me kinda crazy girl

Tell me if you need me right now

Something about the performance, possibly all the hip thrusting and eye contact, was terribly flustering, and she could feel her face heating up. She teasingly blew him a kiss, getting questioning glances from the freshmen sitting next to her. The Trebles shed their jackets, leaving them in fitted black t-shirts and skinny jeans, and Jesse ran a hand through his hair.

"He's so hot," she heard one of the freshmen whisper.

"I know! Do you think he has a girlfriend?"

"I hope not. I could probably take her down, anyway." The Bella let out a snort of laughter before she could stop herself, and the two girls turned to glare at her.

"We should totally go find him after this, oh my god."

[LINE BREAK]

Beca had decided to let the girls go after Jesse first. She already had him, so it was only fair that she let them take their shot. "You were so good! And you're really hot," the tall, blonde one giggled.

"Thanks," he smiled awkwardly, his grin growing as he spotted Beca coming towards him.

"Hey there," he smirked at her.

"Nice work, Weirdo," she smiled back at him.

"Thanks," he wrapped his arm around her, pulling her closer.

"So, like, do you want to go make out? It was pretty obvious you were singing to me," the blonde smirked, glaring at Beca.

"I would love to. With my girlfriend. Come on, Becs," he winked, tangling his fingers with hers and heading back to her dorm.

"Welcome to Barden," the Bella called over her shoulder, the fuming girls flipping her off.

Professor Mitchell was waiting outside the door for her when they got to her room. "Thirty minutes and I'll be good, promise," she said before her dad could say anything.

"Fine, I'll expect you to meet me outside the Lit building no later."

"Yes, sir," she nodded as her dad retreated, hurriedly unlocking her door. As soon as it was shut, Jesse's lips were moving against hers, her back against the door, their bodies flush against each other's. He wasted no time pulling her shirt over her head, moving to pepper kisses down her neck and chest. "Loved the song choice today," she mumbled, breathily, her fingers tangling into his hair.

"Glad to hear it." His voice was muffled against her throat. He led her over to her mattress, the pair falling back into it, Jesse pulling his own shirt over his head in the process. "I love you so much, Bec," he whispered, before pressing his lips back to hers and reaching for the button of her shorts.

[LINE BREAK]

The walk to the Lit building was a rough one. Not just because Beca and Jesse were trying to carry all of her things in one trip, but because they knew, after this, it would be weeks before they would actually see each other. They were both quiet, her gnawing on her bottom lip. "Ready to go?" Professor Mitchell asked as they approached.

"Uh, yeah," she sighed, setting down the boxes she was carrying.

"Alright, well I will give you two a minute to say your goodbyes," he said, loading the boxes onto a trolley. She immediately pressed her face into Jesse's chest, willing herself not to cry. "I'll see you soon," she whispered, her voice muffled by his t-shirt.

"I love you."

"I love you, too."

The car ride to Shannon and Austin's was mostly awkward and quiet. "You really care about that boy, don't you?" Professor Mitchell asked, though he kept his gaze out the windshield.

"Yeah," Beca sighed. "I do."

"I can tell. Is he good to you?"

"Yes, dad," she resisted the urge to roll her eyes. "Jesse is great."

"Good, I'm glad. You deserve to be happy, Beca."
