Interruption

Author Note: Please note these are still just prompts and have in no way any connection to the show or my other stories Accelerando or Cold Days With a Warm Heart other then Sky, which is connected to Cold Days. That's all I wanted to say really.

Also I don't own K-On!

"Onee-chan, are you and Azusa-chan okay with having tempura tonight with some soba?" Ui asked as she looked at the two lovebirds from the kitchen. Yui glanced up from the television with Azusa sitting between her legs and grinned happily while nodding furiously.

"I'm good with that, your soba and tempura are always the best, Ui!"

Azusa spared Ui a side-glance before snuggling deeper into Yui's body and continued to watch the television even though she wasn't really paying attention to it.

"That's fine with me Ui, your food is always good no matter what it is."

Ui nodded and went back to fixing the meal. When her attention was diverted from the couple, Azusa turned in Yui's grasp and began trailing butterfly kisses along her girlfriend's jaw line. Yui's eyes fluttered and tried to stay focused on the television, but it was getting too difficult for Azusa started nipping at the skin, making Yui groan inwardly before her arms tightened around Azusa's waist.

"W-We shouldn't be doing this right here…Ui will-"

"I'm getting you back for all the times you…tried to get intimate with me at my parents house. That was not the way I wanted them to find out."
"I didn't do anything wrong. They didn't find out…" Yui protested as she felt hands slither up her sweater to touch bare skin.

"Having your hands down my pants under the kotatsu wasn't wrong?" Azusa asked as she raised a skeptical eyebrow at her girlfriend before leaning in to firmly bite at Yui's shoulder, making the older girl gasp audibly.

"A-Azusa, stop it!"

"Mmm….no."

"Onee-chan, do you want tea with your meal?"

"H-H-Hai! A-ah!"

Ui blinked in confusion as she heard the startled gasp from the other room and decided to go and check on the two lovers briefly to make sure they weren't doing anything too intimate in her living room. She peaked her head out and noticed Azusa was still sitting between Yui's legs, eyes focused on the television, but then noticed her sister looked a little flustered and red in the face.

"Onee-chan? Are you all right? Is it too hot in here? I can turn the heater down." Ui said making Yui turn to face her once more, giving her a funny looking pout before nodding. "Okay, I'll do that for you." Ui once again disappeared into the house and Azusa once again began to do everything in her power to get back at her girlfriend. Hands pushed up under Yui's shirt once more and Azusa's lips swallowed whatever protests came out of her girlfriend's mouth before she began to fiddle with Yui's bra.

"MmphMm!" Yui moaned against the kiss while her hands tried valiantly to pull the kouhai off, but after a few coaxing strokes of her tongue Yui's self-restraint finally snapped and those hands wrapped tightly around Azusa, keeping her from retreating this time. Azusa smirked into the kiss and even gave a soft moan as Yui began suckling on her tongue while she explored, her hands had finally worked the strap open on her girlfriend's bra and began to fiddle with the bare skin of her breast while pushing herself closer to Yui's body. Each stroke of Azusa's tongue and every caress of her hands against her breast caused Yui to moan even louder and she tried to slip her hands into her girlfriend's shirt when suddenly the tiny hands were clutching her own, stopping her from doing anything.

"No, Yui…this is your punishment…" Azusa whispered seductively before pulling Yui's sweater off her body, but not her hands. She then shifted so she had Yui's hands trapped, making the older guitarist whine against her neck.

"Azuuusa~ don't do this to meeee…"

"I don't know, I kind of like being in control for once." Azusa purred out as she began kissing Yui's neck once more before her hands slide down her sides to her pants, she could feel Yui shaking softly against each caress before her slipped her fingers below the waistband.

"A-Azusa…please…" Yui pleaded as she felt the warm fingers caress her in a way that should be kept behind closed doors. Yui arched her hips forward, trying to get Azusa to touch her more, but the kouhai pulled her fingers away making Yui groan with frustration. Azusa was having way too much fun teasing her lover like this and it showed from the sly grin that was plastered on her face as she took Yui's bottom lip between her teeth and began nibbling on it while giving Yui teasing strokes with her fingers down there.

"A-Azusa…p-please…just d-do it!" Yui yelled in a whisper as she once again tried to use her hands, but the way Azusa was sitting, it just made it more difficult to get them free.

"Nope…not going to."

"Azusa-chan, Onee-chan? Would you like…oh my."

Yui's eyes were suddenly very wide and they could easily see the fear and realization in Azusa's eyes, which were just as wide, as they both turned to face Ui who had just walked in on the two of them. This was most certainly not how they wanted to tell Ui they were intimate, with Azusa practically straddling Yui while one of her hands was down her girlfriend's pants while the other was up her shirt and Yui's hands tied by her sweater that were trapped under Azusa's legs.

"U-Uh…" Was all Yui and Azusa could say as Ui began backing up slowly turning her head to hide the sudden blush as she quickly walked back into the kitchen.

"P-Please make yourselves decent before I come in there next time!" She yelled out furiously as Yui gave a pitiful groan as Azusa withdrew her hands.

"Azusa! That was not how I wanted Ui to find out about us! She didn't have to know about us having se-"

"I know I know! But look at it this way, that was punishment for having my parents almost walk in on us."

"At least they didn't see! Poor Ui must be so traumatized!"

"I highly doubt that since her girlfriend is Mugi-senpai…"

"I would like to think my sister doesn't do what we do…"

"Again, I doubt that."

"Ui! You and Mugi-chan don't have sex right!" Yui yelled from the living room, making both Ui and Azusa blush heavily while Azusa tried to cover her lover's mouth once more.

"You idiot! That isn't something you ask your sister!"
Yui tried to talk against the palm but was having issues since Azusa wasn't planning on letting go soon at all. Inside the kitchen, however, Ui was trying to calm her mind while working on supper. It was nights like this that made her realize that she was lucky Azusa and Yui didn't live there, she would have trouble sleeping at night if they were really that active. But a smile soon graced Ui's lips as she chuckled softly, she may not like walking in on her best friend and her sister doing things to each other, but she couldn't help but be happy that Yui found someone that had the patience to be with her.

"Are you two done being intimate in there?" Ui called from the kitchen. She heard a muffled yes then a pair of eyes staring at her nervously. Yui had got up and walked to the kitchen to make sure she hadn't done any permanent damage to her young sister and was shuffling her feet nervously as she walked towards Ui.

"I'm sorry Ui, Azusa was just teaching me a lesson about…not being intimate while at other people's houses." Yui whispered shamefully while looking at the ground.

"It's okay Onee-chan, I'm not scarred or anything. Just respect Azusa-chan's wishes next time okay?"

Yui nodded before blushing deeply while opening her arms as if asking for a hug. Ui smiled kindly and pulled her older sister into a hug before she felt her phone go off.

"Oh, excuse me Onee-chan, I need to take this…" She pulled her phone out and flipped it open before putting it to her ear. "Hello? Mugi-san? Hai dinner is almost ready so if you're on your way it should be done before you get here."

Yui began hopping up and down at the mention of Mugi's name and whined out while reaching for the phone but was thoroughly ignored as Ui continued her conversation.

"Yes, they should be gone after supper…what's that?..." Suddenly Yui watched her sister's face become redder by the moment before she coughed into her hand before laughing nervously. "N-Not now Mugi-san…Onee-chan's just a few feet from me…"

Yui's eyes went wide as her mind wondered to things that she shouldn't think about, especially if it was about her sister and her best friend. About that time Azusa walked in and heard what Ui said then saw the look and Yui's face and quickly grabbed her girlfriend by the collar and began to drag her out of the kitchen.

"What am I going to do with you, Yui?"

"T-They…they….they do-"
"Pervert."

Ui smirked and watched as Azusa pulled Yui away before turning her attention back to the phone.

"Thank you for calling Mugi-san, you gave me the perfect opportunity to embarrass my sister, I promise I'll repay you for it later after they both leave…"

"I'm glad I can help Ui-chan, please save me some food. Oh, and before I go, I love you."

"I love you too Mugi-san. I'll see you soon."

Ui sighed happily as she hung up, she quite liked having Mugi as a girlfriend, sure Azusa and Yui had been dating longer then she had, but it was well worth the wait. She turned back to the food and thought about all the things her and Mugi would do later tonight while ignoring the rather loud bickering of the other couple in the house. It was going to be an interesting night that was for sure.

Author Note: Hehe, short, sweet, sexy and funny. Even if this story is short, I enjoyed it immensely, being able to write comedy is apparently one of my specialties, as well as tasteful lemons…anyways, just a short little story with some Mugi/Ui in it, maybe the next one I should do some Mio/Ritsu, they were originally my favorite couple until Azusa came on the scene! XD I feel like I've been neglecting them.
