Late posting this one but here it is! Contains strong sexual content and language! I imagine the character of Mandy being similar to Sadie Sink.

Kate was bombarded by these green freaks that took over the Dorry's Bar, she was at their mercy serving them whatever beer and food was left, it had been hours behind the bar, the little monsters pulled the phone line out of the wall and one of them even had a gun. There had to be more than 50 of them now all dancing and drinking together and causing damage. This was all a living nightmare, from what she could see outside the rest of the town was no better, she could see fire, cars crashing, these invaders were destroying everything and taking over like it was a warzone. In the darkness, Kate swore she saw a light bouncing outside in the distance and it was getting bigger, it was someone riding a bike in her direction. No time to see who it was, one of these things was in her face wondering why this wench would stop pouring them another round.

"Ok! Ok!" She said, filling up another pitcher.

"Kate!"

Kate was shocked to see her younger sister Mandy rush through the door, the 18 year old didn't bring anyone with her, no police or even an actual weapon, just her flashlight.

"Mandy! Get out of here!"

Mandy only just realized how swarmed Dorry's was with these monsters, she jumped over the bar in a seemingly futile attempt at saving her older sis.

"Get back!" Mandy said, holding the flashlight above her head, ready to strike one of them, "Kate, what are these things?"

Kate assumed she must have encountered one of them in the streets but it looked like she'd been oblivious for some time. Mandy accidentally shined the light in the red eyes of the one hassling for more beer from Kate and blinded him. Both Kate and Mandy were surprised to see how much the light hurt it, when more of the green skinned weirdos got close, Mandy shined the light in their eyes so that they backed off.

Mandy took Kate's hand, "Come on, we're getting out of here!"

They leaped over the bar, ready for an epic exit but were crowded by more of the pint sized jokers, Mandy tried blinding them but the light quickly dimmed, the battery died. The mob of them laughed, showing off their scary pointy teeth.

"No! Are you kidding me?!"

Kate held onto her kid sister, shielding her as the monsters advanced. Oddly the one with the stripe on his head made all of his friends stop, something above the two sisters got his attention. Kate and Mandy looked up to see a hanging mistletoe, Kate forgot it was up there. The green freaks chanted something, it was difficult to make out but Mandy thought she knew.

"Kiss? Kiss?"

"Huh?" Kate said, confused.

"I guess they want us to kiss?"

Kate bit her lip, she wasn't sure just how serious they were, "Well we better do as they say."

Kate planted a quick kiss onto Mandy's soft cheek and waited for their approval. All of them made buzzer sounds and gave Kate a thumbs down.

"Hey! What do you expect?"

"Kate," Mandy said, nervous at what these things might do, "I think they want us to kiss-kiss."

"KISS-KISS! KISS-KISS! KISS-KISSSSS!"

The chanting continued, they threw beer bottles around, smashing them to make their point.

Kate was appalled, "She's my freaking sister!"

"KISS-KISS! KISS-KISSSSSSSSSS!"

"I don't think they care."

Kate rolled her eyes, "I cannot believe this."

Mandy wasn't sure what they got out of making them kiss each other, it had just be for their sick amusement but she was cold and tired and just wanted to go home.

"So are we really going to..."

Kate took Mandy's hand, "Don't look at them. Look at me. Ok?"

Mandy nodded. Kate pulled her in close. She smiled nervously, pretending nothing was bothering her. She didn't know if things would be ok. How could she? She already hated the holidays and now this? She knew for a fact they couldn't tell anyone about this. She wasn't even sure if Mandy had even kissed by anyone before. 'Well I guess I could teach her a thing or two,' she thought, 'Shit, this is so wrong...'

She closed her eyes, Mandy followed, she didn't know what to expect. She didn't exactly imagine what it would be like to kiss her sister of all people! Kate's lips came at her like an oncoming truck, her mouth latching onto hers like it did was surprising. It was so wet. It was so weird.

The creatures made it clear they were enjoying themselves.

"WWWOOOOOOO!"

They all exclaimed like a studio audience.

It was so awkward. It was so tasty. It was so...

Kate and Mandy parted lips and stared at each other. Kate had seen sparks.

"Whoa," Kate's breath had been taken away.

"Huh?" Mandy thought something was wrong.

Kate gulped, she wouldn't admit she liked that.

"Should I have used...tongue?" Mandy said innocently.

"TONGUE! TONGUE! TONGUE!"

Kate clenched her teeth and face palmed, "Great. You just had to say that didn't you?"

Mandy gritted her teeth into a nervous smile and shrugged.

The crowd made lip smacking sounds, anticipating them to go for a second round. Begrudgingly they did so, this time both latched on maybe a second longer than needed. Their tongues swam freely in each others' mouth until they crashed into the others', fighting violently. Both swore they heard the other moan when they pulled away. Kate lost her balance a little, all of the creatures noticed and giggled to each other.

"Sorry," Mandy said, scared she made Kate feel disgusted with herself for doing that. "That was my fault."

Kate took a moment to fix her hair and even fan herself a little; was she turning red?

"No, Mandy! It wasn't your fault!" Kate got angry and shouted at the green nuisances, "It's these monsters!"

"RED! RED! RED! RED!"

They all mocked her cheeks from being so red after that second kiss.

"RED FROM BEING ANGRY!" Mandy protested, defending her sister.

Mandy took Kate's hand.

"YEAH! YOU FREAKS!"

The creatures laughed, they seemed satisfied with what the pair had done for them, some even moved aside to make a small path for them but Kate scared Mandy with a strong grip on her hand.

"Wait! They want us to do it again!"

"Huh?" Mandy was confused, most of them were back playing pool, making any other attempt at a taboo kiss was long over.

"Don't you see! They want us to keep doing it!"

"But Kate I think..."

Kate touched her cold face, "Mandy, we just have to do this a little longer and then we can get out of here."

The window of opportunity to leave was wide open but Mandy always listened to Kate so she decided to do as she said.

"And maybe more tongue this time ok? Massage mine with yours."

Mandy nodded, still curious as to why she was so insistent.

The two kissed again, cheered on by the others that were still hanging around. One of Kate's legs lifted up like she was in some rom-com where she just met the perfect guy.

"OOOOOOOOO"

Mandy sucked on the bottom of Kate's lip and tugged on it a little as they parted. The look Kate gave her suggested something serious but she didn't understand, she was looking at her with sultry eyes. She told her to hold her gaze, put on a show.

"Wow...Kate that was...Should we maybe go?"

Kate pulled off her sweater and showed off her bra, the monsters were loving this.

"Kate! What are you..."

"Didn't you hear? One of them shouted for me to take my top off!" She looked disgusted but she showed no hesitation in stripping.

Mandy looked back at the crowd of them and frowned at no one in particular, "PIGS!"

"They are Mandy! And they want you to strip now!"

"What?" Mandy knew she couldn't have heard this.

"Take yours off too or else they said they'd eat your face!"

Mandy didn't know what else to do so she threw off her jacket and pulled her sweater off, Kate helped her with her shirt. Of course Kate was older, more mature, her breast size was bigger, she had on a black push-up bra that didn't completely cover her. The creatures acted rowdy when they saw her do this. To Mandy's shock, Kate seemed to enjoy this attention; she only stopped basking in their praise when Mandy caught her.

"Come on, Mandy! What are you waiting for?"

Mandy scowled, when all of this was over they needed to have a talk. Mandy set her shirt down on a stool nearby and everyone got a good look at her, the little bastards were applauding.

"Ok," Kate said, realizing both of them were standing there with their tops off in the cold bar; maybe coming to her senses that no one was telling them to do anymore too.

"Time to go?"

"Yeah," a look of worry spread across Kate's face. She got way too carried away.

Before she could get her sweater back on one of the little jerks ripped her jeans with one swoop of its claw and they fell around her ankles. Mandy wanted nothing more than to stomp on the creep. It giggled evilly and gave Kate's butt a good smack. Mandy was livid but Kate was hiding a smile. Her butt cheek jiggled.

"Hey!" She couldn't even pretend to be upset, her enjoyment was clear to Mandy now.

"Kate!" Mandy exclaimed, thinking her sister was losing her mind.

"You, know Mandy maybe we've got these little guys all wrong. I mean they seem to just want to have a good time."

Mandy grabbed her sister and gave her a hearty shake.

"We have to get out of here! What are you doing?"

Kate smiled at her sister, "Mandy, I think you need to let loose ok? Let's have a good time."

She touched the bottom of Mandy's chin, encouraging her to have it up with eyes on her. Mandy caught her looking past her and smiling at someone, like she was being set up. The next thing Mandy felt was her pants being ripped off of her. She gasped, behind her was one of them holding her new denims. Mandy covered her white panties with little red hearts with both hands.

"Come on, sis. They're just being friendly!"

"BUT KATE..."

The Striped one turned on the jukebox. Something funky was coming on full blast. It was Brickhouse by the Commodores. Mandy yelped out when she felt herself being pushed by the small lanky arms to the bar, Kate giggled, giddy for what she knew was about to happen.

"I think they want a little dance."

"Dance? You can't be serious." Mandy had never danced in her life; not in front of other people anyway. But these weren't people they were gross little monsters.

Beer bottles were shoved in front of them.

"N-no thanks! I'm not 21!"

Kate nudged her, "Come on, go for it. You probably won't even get drunk."

Mandy took a bottle and drank a sip of it, the most disgusting thing she'd ever tasted in her life, she thought she was going to throw up. Kate patted her on the back, "Yeah, it's an acquired taste."

Kate chugged a good portion of her bottle, Mandy tried again, deciding to pain through it but she couldn't finish the whole thing, it was just too much. Kate helped her up on a table.

"What do we do?"

"Just do what I do!"

Kate danced, swaying her body to the music, Mandy was impressed by how talented she was, she did have a great body but she knew she would never be able to move like her. Mandy almost lost her balance on her first sway, Kate told her to keep looking at her, she swayed her hips, gyrated to the music, it was goofy but their audience seemed to enjoy it. Mandy wasn't sure if it was the alcohol but she thought she was having a good time. She shook her whole body just like her sister. They shook their butts, both wobbled and jiggled. Kate insisted on dancing close together, grinding their bodies into each other. Kate liked the touch of Mandy's soft skin against hers. Mandy thought it was hilarious when they rubbed their butts together during the dance but realized that it would come off as sexy to the red eyes watching. Both were sweating now, Mandy was abruptly pushed into a chair, she thought it was one of the little freaks but was shocked to see it was Kate.

"Huh?"

"Watch this!" She smiled and winked.

"Kate," Mandy gulped, "Don't you think it's time we went home?"

Mandy sat there on edge with all of those weirdos around, her hands gripped the arm rests. Kate gave her a lap dance like she was a sleazy stripper. Mandy wasn't sure what to think. Her sister must have fully lost it. Kate rubbed her butt against her crotch, she bent over and shook it in her face, her black panties were see through, Mandy could make out her cheeks and crack. Maybe she was the one losing her mind because she thought this was awesome! Kate climbed into Mandy's lap facing her now, she did a sexy strip tease in removing her bra and tossing it back at the rowdy bunch like it was a corsage at a wedding. The beasts fought over the bra, tearing it to shreds.

Mandy's face couldn't have been any cuter with her eyes bugged out at her sister's breasts. Kate laughed and pushed them into her face and shook them. Those bastards cackled, they never wanted this show to end now. Mandy wanted to push her off of her but Kate was pretty strong. Kate kissed her again, this time it was a lot more hot and heavy, passionate. She nibbled on her ear, pecked at her neck and went right to Mandy's breasts. She pulled at her bra with her teeth. Mandy could only wonder if Kate was turning into one of these things like some weird Sci-fi horror movie they'd catch down at the old drive-in.

"Kate! Would you snap out of it?"

Kate successfully removed her bra, she wiggled her eyebrows at Mandy and tossed it from her mouth like a dog. Mandy didn't have time to cover up, Kate dove right in, sucking on her breasts like there was no tomorrow. She lapped her tongue around her hard pink nipples. Mandy was enjoying it, it did feel good even if it was inappropriate. Her boobs of course were nowhere as big as Kate's but they were perky enough to get everyone's attention. The chair ended up falling backwards with the two in it, comically with their feet up in the air as Kate continued to kiss her. Both found themselves unable to help themselves, lust for each other was intoxicating.

"Oh! Oh! Mandy! I'm sorry I just can't help myself...I...I..."

"Oh! Kate! It's ok just...just don't stop please!"

They rolled off of the chair, they were out of their snow boots, their panties came off somewhere on the way to their final position. Both naked and in heat, Kate only wanted one thing. Kate lied on top of Mandy, her ass and pussy in her face, now Mandy's pussy was in hers.

Kate was gorging herself on her sister's cunt, her tongue burrowed deep inside her. She moaned as she savored the sweet flavor of pussy. Mandy couldn't resist her sister's lashing tongue. She was beginning to feel hot, and her pussy was beginning to get wet. Her thighs spread wider. Mandy plunged three fingers into her big sister's pussy. So wet!

Kate's breath rasped, her face reddened. Her breasts mashed against her sister, Mandy's fingers sloshed as they pumped relentlessly in her flowing slit.

'God... I can't stop myself...' Kate thought, as she pushed herself back harder against her little sister's face. "Ooooo... Mandy!" she groaned aloud. "D-d-don't stop! Fuck my pussy!"

Mandy grunted in response, and eased a fourth finger into Kate's dripping gash. She bunched them together, twisting them with every thrust.

By now Kate had accepted what she was doing, drunk or not she was doing something she shouldn't be with Mandy but Mandy was calling out for more too, she was feeling exactly what she was. Mandy found Kate's clit and knew exactly what to do with it. Kate screamed, but it was a scream of pleasure.

"Fuck, Mandy! Fuck me! FUCK YOUR DIRTY FUCKING SISTER!" Kate wailed. Her body shone with perspiration.

"OH FUCK! YES! KATE! FUCK!" Mandy let it all out, Kate's sweat mixed with her own.

"FUCKING FUCK! YEEEEESSSSS!" Kate screeched, as she pounded her body violently on top of her sister.

For her part, Mandy held Kate tightly, her fingers dug into the older girl's ass flesh, she loved how big it was, fun to squeeze and hear her sister yelp more.

Kate slurped and licked at Mandy's asshole, getting it good and wet. Once she was satisfied with the amount of spit she'd coated it with, she moved her lips higher, giving her sister's cunt a slobbery kiss. Two of her fingers pressed into the younger girl's ass, forcing their way into the tight, dark channel.

"FUUUUUUUUUUUCK!" Mandy's face was bright red and her eyes bulged as her anus stretched around Kate's fingers. The spit allowed them to plunge deep easily, and the sensation was overpowering.

At the same time, Kate had started to again eat Mandy's pussy in earnest, laving it hungrily with the flat of her pink, flicking tongue.

"Mmm..." she groaned between licks. "You taste... so... good..." She speared her tongue inside until her nose was squashed between Mandy's glistening lips, and gorged herself like a starving animal.

"Yesyesyesyesyes! F-f-faster! HARDER!"

Both were squirting juices into each others faces and all over the floor of the bar. It was a sight for the ages, both had exhausted themselves. Kate climbed off of her dear younger sister and lied on her side to face her. Kissing once more, still with heated passion, the girls made out ferociously, saliva running over their chins as their tongues dueled. Kate held Mandy's hair bunched tightly in one fist. The younger girl gasped for breath when she was finally able to pull herself free. Her face was covered in saliva and glowing bright pink from the heat. They moaned and grunted as they slurped up their combined cum, their noses bumping as they fought for more of the intoxicating flavor. The two sisters kissed sloppily, their tongues drilling into each other's mouths.

After several minutes of deep kissing, Kate began to move down her younger sister's body, she again attacked her breasts savagely, sucking the warm flesh into her mouth and biting the sensitive nipples. Kate looked into her baby sister's eyes and groaned. Saliva dripped from her chin, landing on Mandy's bite mark covered flesh.

One of the little green devils turned the open sign to 'CLOSED' and joined his friends as they filed out of Dorry's and journeyed out into the night to wreck more havoc on the small town.

Kate had her legs wrapped around Mandy, the two continued to kiss, their sweating bodies glistened against each other in perfect harmony. Neither paid attention to the loud events taking place outside, as far as they were concerned they were the only things that existed in the moment.

Kate took a moment to just look at her sister and brush her red bangs back with her hand.

"Thank you for coming to rescue me."

"Kate."

"Yes, Mandy?"

"I -I love you."

Kate smiled.

"I love you too."

They kissed once more.

Merry Christmas and Happy Holidays!
