Airi and Mali: Forever and always

As another day goes by, Mali and Airi return home from work as both relax for the weekend. And while the two settle down on their couch, Airi lays her head on Mali's shoulder. "You want something don't you?" Asked Mali, Airi giggles from her question,
"How'd you know?"
"Because you're acting cute!"
"Well there is one thing…"
"What's that?"
Airi explains how her younger sister is coming into town and was wondering if she could stay in their place. Mali is a bit unsure since Airi hasn't said much about her family, Mali herself doesn't have any since they died years ago.
"How long did she say she'll be staying?"
"Oh just for a few days, she and I haven't talked in a while so it'll be nice to see her again!"
"So is your sister…y'know…"
"She is! But don't you get any ideas Mali! She's bringing her girlfriend!"
Mali chuckles as Airi blushes, "Fine! But promise me if they give consent, I can do whatever I want!", Airi blushes more as she turns away from Mali, "Hmph! You're such a perv!" Airi then sees Mali looking down as she apologizes for bringing up such an idea. Not being a person to hold grudges, Airi sighs and clenches her hand into a fist and has her pinky out, "Only if they say ok!" Says Airi. Blushing herself, Mali pinky promises with Airi and says it's ok for her sister to stay.

About a week later the two get the apartment ready for Airi's sister, with Airi taking what seemed to be forever in Mali's opinion getting ready in the bathroom. Then as the two check for anything misplaced, they hear a knock at the door. Airi rushes to the door and slowly opens it, only to be knocked down on the ground by a hug tight all while hearing, "AI-CHAN!!!". Mali rushes to Airi but sees her laughing with a blush as she gets up speaking Japanese to the girl. Mali sees a girl with white hair, blushed cheeks, and looking identical compared to Airi, "Umm! Mali this is my little sister, Yuka! Yuka, Mali!". The two greet each other as Airi sees what appears to be Yuka's girlfriend with black hair much like Airi's, blue eyes, and with a gentle smile. "H-Hello! I'm Nicole! Y-Yuka's girlfriend!".

All four greet each other and then Airi and Mali help with luggage. Afterwards, the girls sit down on the couch and have some interesting conversations along with a few drinks. With empty drinks, Mali goes to pour some more for everyone, but Nicole follows her as Airi and Yuka continue to catch up. "M-Mali right?" She asks
"Something wrong Nicole?"
"No! Of course not, it's just…do you know about them?"
"Them?"
"Yuka and Airi, and how they…"
"Oh! Yeah I know about it! Just happens to be that I myself am invulnerable!"
"Really? Wow! I didn't think there'd be anyone else other than Yuka and I to be immortal!"
"I guess that's pretty…wait you're immortal too?"
"Y-Yeah! And it's a bit of a turn on when we go limp!"
Mali stares at Nicole as the two blush, and coincidentally both are having the same idea.

Meanwhile, the two siblings were still catching up with stuff such as Airi complimenting Yuka about how she dyed her hair white, soon it got quiet which led Yuka to bringing up a question, "So you're girlfriend's nice! How'd you two meet?"
"Well Mali and I met at college, but it was a few months after we actually hung out with each other, it was just fun at first, but we were getting more intimate as time went by!"
"Aww! So cute!!!"
"Shut up! I bet it was exactly like that when you and Nicole met!"
"Well…" Yuka began to blush as she was thinking of how she and Nicole found each other, but the more she thought, the more she showed she was getting turned on as Airi sees her nipples getting hard through her shirt, "Y-Yu?". Suddenly, Nicole and Mali come out with lewd faces, Nicole staring at Yuka, and Mali at Airi. Mali stumbles her way to Airi as she kisses her cheek and begins giggling, "Y-You have no clue how drunk Nicole and I are!!",
"I think I have a rough idea!" replied Airi, "So, Nicole and I were talking, and she says that she plays with Yuka like we do." Yuka blushes hard and frowns at her drunk girlfriend, "N-Nicky!!!"
"Sorry Yuka! But I know you've been wanting to play with your sister!"
Airi and Yuka are blushing really hard and cover their faces. "I-I have a confession to make," says Airi, "I've wanted to play with you as well sis!" Airi then kisses Yuka on the lips as she kisses back deeply; that's when Mali gets an idea, "Why don't we play a game i like to call 'Limp roulette'?", the other girls are curious and ask how to play as Mali grins.

"Well, think of it like Russian roulette, except with a few alterations," Mali then makes everyone sit down on the floor around an empty wine bottle, "so here's how to play, we spin the bottle right? And when it chooses one of us, that person can choose to be the other players play toy or withstand! If they withstand, we go again, if it goes to the same person twice, they have to be snuffed! Once someone chooses to be snuffed, they have to wait as the rest go again! The goal is to be the one who doesn't have to be snuffed! Winner gets to kill losers and have fun with their bodies!" Airi, Yuka, and Nicole smile as they really wanna play this game. Although, Airi gets another wine bottle and sets it between her and Yuka, "Why don't we have it like a competition?" She says as she sees her flustered sister. Immediately Airi spins the bottle as she bites her lower lip in anticipation and arousal, and just like she wanted, the bottle points at her sibling. Yuka shows signs of being turned on again as she starts stripping nude, "I-I want you to take me Onee-chan!". Meanwhile Nicole does the same thing as the bottle points to her, rubbing herself doing so. "Mm! Such sexy girls for us to snuff Airi!" Says Mali as she and Airi get nude as well, before anything else, Yuka and Nicole kiss each other one last time, then nod as they're ready to be played with.

Deeply kissing their victims, Airi and Mali wrap their hands around Yuka and Nicole's throat. Yuka moans through her sisters fingers and begins to struggle a bit, all while Nicole starts rubbing herself on one of Mali's thighs. Both Airi and Mali take their time with killing their soon to be toys, making sure that they're struggling while having it feel erotic for them. Moments pass as both victims slow down from their struggles, slowly fading as they get closer to cumming. Mali chokes Nicole tighter and tighter, making Nicole's eyes roll back and arch until Mali hears her neck break, making Nicole cum hard and go limp. Mali kisses Nicole and starts to scissor her corpse, "Mmm! Nicole is gone now!" Says Mali, "How's it looking for you Airi?", "Almost done here!" Replied Airi, unlike Mali, Airi doesn't tighten her hands around Yuka's throat, instead she applies just enough for Yuka to feel herself cumming as she dies. Yuka stares into her sister's eyes as she's about to fade, trying to say that she loves her, but all that comes out are her dying gags, Airi goes to whisper in Yuka's ear and tells her, "I love you Yuka…" as she then kisses her goodbye. With that kiss, Yuka cums really hard as she follows Nicole and goes limp.

The girls play with their victims for a few hours, up until Mali take a bottle and spins it between her and Airi. "Wait!" Screamed Airi, "I wanna be raped Mali! Please!", with a dubious grin, Mali goes to her room and pulls out a wire garrote she's been wanting to use for a while. Still scissoring her sisters' corpse, Airi feels something very thin around her neck, "Does my sweet Airi wanna beg?" Asked Mali, and with a kiss, Airi replied with, "Rape me please Mali!". With Airi's consent, Mali pulls on the wire and lifts her slightly up into the air. Airi begins struggling, kicking for air, and gagging so cutely it makes Mali pull tighter.  Mali then begins to hold both sides of the wire with one hand and takes her other hand to finger Airi in between her legs. Airi's insides tighten around Mali's fingers as she was beginning to twitch, Mali then brings her closer and tells her something before she fades, "Sweet dreams my sweet slutty Airi!". Airi cums hard from hearing Mali's words, and with tears pouring out of her eyes, Airi has one last thought, "I'm your slut Mali…forever and always…" Airi then goes limp as her corpse cums again.

Mali takes all three bodies into a room as she thinks for a moment what to do, but looking at Airi's pale corpse, she goes nuts and carefully set Yuka and Nicole's corpse to the side and caress's Airi's body. "Oh Airi," she says as she starts fingering herself, "I love you! I want to love you forever!" Mali then started to scissor Airi's cold body and kissing her as she pulls out a knife she's had planned for a night like this. She then launched the knife into her stomach as she moans in pain and lust as she cums over Airi's body. "Ahhh! I…I love you Airi!" Mali takes the knife out and stabs herself directly in the heart, then pulling it out so it heals later. Mali kisses Airi one last time before she herself succumbs to death over her lover, leaving only four lifeless bodies throughout the night.

To her surprise, Mali is the first to be fully healed and wake up, she looks around and sees Nicole and Yuka healed, though they seem to be cuddling each other in their sleep, as for Airi, she seems to be waking up herself. With a cute moan, Airi opens her eyes and sees Mali, "Good morning Mali!" Says Airi, "Hehe there's the girl I fell in love with!" Mali replied. Airi blushes a bit afterwards, but then she sees the blood over Mali, "W-What did you do last night?". Mali pulled out the knife she used and giggled, "I've been wanting to use it for a while, just didn't know when." Mali blushes herself from slight embarrassment. Once Airi sees her blushing, she hugs Mali tight and says, "I love you Mali!". Mali hugs back and in the heat of the moment says, "Do you wanna get married?". Airi gasps and her heart pounds like crazy, but without a second thought, she nods with a brighter blush on her face. Both crying in joy, Airi and Mali hug and kiss each other as the other two love birds wake up. "W-What's going on?" Asked Yuka, Airi and Mali had forgotten for a moment about their guests, and feel more embarrassed then before.

An hour later, after a brief shower to take the blood off of each other, Mali pins Airi against the wall and makes out with her as the water pours down on them. Yuka and Nicole knock on the bathroom door to get their attention. "What's taking so long?" Asked Nicole, "Sorry guys," replied Mali, "You'll have to wait a little longer!!!" Airi giggles as she wraps her arms around Mali then Mali returns the favor and wraps her arms around Airi's waist, "Eventually I'll get you that ring Airi…right now I'm not so great with money." Airi chuckled and shakes her head, "It's fine, we're immortal! We'll be together forever!"
"R-Really?"
"Yeah! As long as you still call me slut!!!"
"Hehe alright my slutty Airi! You're mine forever and always!"

Afternoon comes by as all four girls relax by the couch with Airi looking a bit down. "What's wrong onee-chan?" Asked Yuka, "Oh nothing, just you two will have to leave soon…", "Actually," interrupted Nicole, "I did happen to see your neighbor moving! And we've been looking for a new place anyways! Right Yuka?" Yuka nods as a reply and looks towards her big sister. "Airi! Could you help us with our stuff please? Nicole and I aren't all that tough as you can tell!!" All four girls giggle; and so Yuka and Nicole go to talk to the manager as Airi and Mali hold hand while watching tv. "Hey Mali, when do you think we can get married?" Asked Airi, Mali took some time to think about it and said, "Not a clue love, but if by any chance we'd get immediately rich, the first thing I'd do is take us to Vegas to get married! If ok with you of course!" Airi smiled with a light chuckle and kisses Mali and replies, "Forever and always!"
