I don't know where this came from.

Rated for a reason though, guys! If you don't like random smut, I suggest you don't read.

Don't Get Caught

Ever since they had started dating, Luka seemed to have an obsession with touching Miku. Normally she'd just rest her hand on her hips or slide them down her back, caressing her cheeks and legs... but then, after about a month, Miku started noticing a pattern.

It was like watching a dying dog search for water in the middle of the desert, the way she'd be all over Miku, needing to touch her in some form. They weren't the couple to jump straight into sex (okay, that was a lie), but when they did, Luka proved that her libido was just as high as a drunk Haku and could nearly go all night and beyond if she wanted.

That soon somehow came into the public, and Luka would randomly start touching Miku in places she shouldn't be touched in public. Grocery trips ended with the older woman waiting outside, going to the mall forced Miku to keep Luka out of her dressing rooms. It wasn't annoying or pathetic, and Miku did find it cute, but she didn't trust herself with Luka out in public either; she just had a knack for keeping it from showing.

But sometimes... it was really hard to keep their hands off each other.

"L-Luka..." Miku whispered, trembling with her eyes wide. It was nearing one in the morning, the two randomly deciding to go out and buy some snacks, and here they were in the back with Luka's hands sliding up Miku's stomach.

She hummed against the girl's ear, warm breath fanning her skin lightly, "No body's watching," she said, making sure to glance to the side. Luka's fingers danced lightly over Miku's stomach, the wiggling of her body forcing her chest to press more into her back.

Miku gripped the handle to the drinks tightly, trying her hardest not to make a sound from the light touches her girlfriend was giving her, gulping when one of those hands made it to her bare chest. Being really late at night she didn't see a reason to put on a bra, but now she wished she did. "Luka... you have to... to... stop!" she gasped at the feeling when Luka started massaging her chest, her squeal making an employee start to make his way over.

"Oh no," Luka said dully, a sinister smile on her face. She leaned down to get something out of the cold racks, holding it up to her face, "They only have green tea with lemonade, Miku..."

The younger girl ran a hand through her hair, smiling at the confused clerk to show they were fine, then stomped on Luka's foot, "You're horrible!" Her eyes showed nothing but irritation, but the small streak of red on her cheeks said otherwise. Luka had another sudden urge to mess with her, but the pain of her foot yelled at her to avoid doing that.

Wincing, Luka kissed her neck and stepped away from her back, "Well you can't say you didn't enjoy that, now can you?"

Miku huffed, turning away with her nose up in the air, exposing her blemish-free neck. Dark teal eyes stared at a certain spot, and Luka stepped closer, placing her hands on the shelves behind Miku to keep them steady. She leaned closer and turned her head to place her lips on her favorite spot–

"Oh no," Miku said, pushing her face to the side, "You're not getting anything tonight."

Luka frowned. "Why not?" she asked quite childishly, pouting. When she pouted, Luka either meant it or did it just to break Miku's barriers, so the tealette knew what she was trying to do, and vowed to ignore it. "Come on, Miku.."

Her hands released the shelf to slide up and down Miku's waist, both of them now away from the clerk's nosy eyes. However, Miku wasn't about to have it, "Nope. Now let go."

"But–"

Miku stepped on her foot again, glaring at her and feeling all too much like a mother, but once she saw the kicked puppy look on Luka's face, she sighed. "One. Just one, Luka," she said, moving her hair away from her neck. Her sweater was proving to be very useful, as it could cover up the mark she knew Luka would give her; she was too nice for her own good.

The moment Luka's lips descended on her skin, she reached out to grab the shelf, biting her lip to avoid making too much noise. She would never admit that Luka was a pro at kissing, and she surely proved that whenever they were in situations like this; it was a huge reason she could never resist her. "Ngh," she winced, slapping Luka's thigh when she felt her bite her neck a little too hard. Her naughty girlfriend could only chuckle and lick the mini wound, blowing on it.

"If you keep that up I'll..." Miku was about to reprimand her, but found herself grabbing a packaged energy bar and stuffed it into her mouth, biting it hard enough to break the wrapper. Luka's hands sneakily made their way into her shirt, or one of them, lightly brushing her stomach, and the other groping her breasts from the outside. "Luka..."

Luka, of course, was too busy being in heaven to worry about Miku's silent cries. Her eyes were glazed over and only registered the pale skin she wanted to bruise and mark with her teeth, and her body was shaking from her obsession with the girl in her arms. "You..." she whispered, licking the shell of Miku's ear, "Taste like blueberries."

Miku's face went from being in a state of euphoria to completely embarrassed, although she didn't have the strength anymore to push her away, and turned around, wrapping her arms around Luka's neck. "You are so stupid," she laughed, pressing their lips together, letting one hand drag down the front of Luka's chest to squeeze lightly, and frowned, breaking their kiss to focus on the chest she had seen countless times, "You have such huge boobs..."

"Eh, they're okay I guess. Pretty annoying," Luka mumbled, swooping down to bite on her favorite spot on Miku's neck. Having her hair down, she ran her hands through the soft teal locks and bit even harder at the feeling of Miku's hands going dangerously low, already infiltrating her sweats. One of her hobbies was dancing, and of course this night she had chosen to wear her insanely large but tight sweats, allowing Miku easy access to what was inside. "I dare you," she whispered in need, biting on Miku's ear with a groan of satisfaction when she felt Miku's piano-like talent press against her. "M-Miku... I think we..."

The younger girl, smirking into her chest, bit lightly on her skin with an evil chuckle, "Oh? You wanna back out now, huh? That's a first." Her emphasis wasn't to tease, but it was the effect of her harshly pushing her fingers against Luka's panties, knowing that not only did the pinkette like it pretty rough, but she absolutely hated when she teased.

Eventually, Luka seemed pretty tired of the teasing and showed it by actually biting Miku's shoulder, "Miku, I swear if you don't," she growled in sexually frustrating anger, shocking the tealette by how low her voice could get. Nodding, Miku licked her lips seductively at the same time she dove in, feeling warmth and stickiness everywhere. Luka barely got a moan out and was forced to endure biting on the already ruined energy bar, hating the taste of actual blueberries. "Oh god..." she whispered, pressing her sweaty forehead against Miku's hood.

Not stopping for a second even though she felt her fingers starting to cramp, Miku kissed the side of her head, feeling herself become a little hot and uncomfortable herself; they wouldn't have time for any of that though, so made sure to get Luka to climax for the both of them. "Come for me, Luka..." Miku said as low as she could, biting and licking Luka's earlobe for an added effect. "Come on..."

It didn't take long, and Luka had to resort to biting on Miku's shoulder once again, staining the light blue sweater with streaks of dark blue from the energy bar and darkening the fabric from her saliva. "Oh man..." she panted, throwing the bar somewhere to the back of the shelf. Their drinks were on the ground, and she made sure she looked presentable before picking them up, watching in horror as Miku nonchalantly started licking her fingers as if she had just eaten something sweet. "You're horrible," she laughed, slinging an arm around Miku's shoulders to shield the mess.

The clerk seemed a little suspicious, especially when Luka wouldn't let Miku go aside from taking out money from her pockets, the younger girl playing with the zipper of her sweater with an innocent smile. He simply shook his head and silently rang them up, watching in curiosity when they latched onto each other, opening up their drinks immediately with smiles on their faces. It suddenly made him smile, and he watched them go with a shake of his head. "Kids," he chuckled.

Luka took a large intake of her energy drink and smiled down at the content Miku, who gave her an innocent glance. "Pretty night, huh?" she asked, looking around at the brightly lit part of the neighborhood. Miku nodded, resting her head on her shoulder.

"Last one home is on bottom."

"You're on!"

Hope you liked it!
