“Damn, Rubes! Just look at all this fucking ASS you have on you! Hah, I know I’m pretty top-heavy, but I wish I was packing a real wagon like you were!” Yang Xiao Long teased her little sister Ruby Rose, clinging to her from the front and reaching back to grip her fingers into all of that plush thickness.
“Yaaang, s-stoooop! It’s embarrassing when you rub up my butt like that! Sisters aren’t supposed to do that kind of thing, that’s so weird!” Ruby struggled to escape from her sister’s hold. Not that she could get away from such a steely hold on her asscheeks, and she wasn’t putting up a real struggle in the first place!
It was a common thing for them to do. People nicknamed them ‘The Scissor Sisters’ because it was obvious they had some sort of very unwholesome feelings for each other. The truth of the matter was, they never pursued it – cases like these were the most severe.
Here they were again. Clad in their pajamas. In the usual spot. Yang gropes up Ruby like fuckmeat and makes the redhead think she might finally take things further. Ruby whimpers and basically humps into Yang while trying to ‘escape’, begging to get taken already. But they would always get too nervous to really go through with it.
You can smack and spank on your little sister’s juicy wobblewagon all you want, even doing so until she feels like she’s going to squirt against you. But once you bend her over and stick your cock balls-deep inside to give her a baby, that’s a whole different ball park!
Ruby and Yang were silent, just looking into each other’s eyes. Yang’s luscious purple gleamed with lust, and Ruby’s enchanting silver shimmered with anticipation.
Oh, and their private parts were also rubbing all up on each other because of the way Yang’s erection was stuck between her little sister’s plush pillars of thighmeat. She was sopping wet, as was Yang!
“S-So… sis. Heh. Gosh, we’re still s-sweating our asses off from working out earlier, hahah! Maybe we need to get out of these nasty, sticky clothes and take another shower, huh?” Yang offered.
Ruby licked her lips, humping across Yang’s mast. “Yup! A-A long, hot and thorough shower until w-we’re completely clean! You’ll help me scrub those hard to reach places, right~?”
The firm squeeze given to Ruby’s cheeks was enough of an answer.
She licked her lips.
Yang smirked.
They were only gonna walk out of that shower even dirtier.
“GLRRK! SHLURRP! SHHLORSSHPP, MMGFHH~💖”
“Hhnfghh, FUCK, just like that! G-Gag on Mommy’s dick with those pretty lips, get it nice ‘n wet so she can stick it up that juicy ass of yours..~”
Ruby bobbed her head swiftly, blowing her sister so hard it was like she was somehow using her semblance to suck cock like a champ. Yang had forced them into a standing sixty-nine, probably because manhandling her sister like that seemed like so much fun.
All the foamy spit applied to her meatlog was probably enough by now. Ruby knew this, but it wasn’t like she could exactly bring the point up. Feeling her throat flex and coil around Yang’s sisterly slutbreaker was all she was capable of. Did her sister taste good because she was her sister , or was it genuinely delicious? The answer: YES.
Yang herself ate out her sister’s pretty little pussy with a vengeance . Ruby knew Yang was a total stud. She brought countless boys and girls home, and they all left with a limp and a not very subtle trail of cum leaking down their thighs.
… And Yang always saw them off with her still leaking dick hanging out of her shorts. There was one common thing they all screamed while still there: “OOoghhH H-HOW CAN YOU USE YOUR MOUTH LIKE THAT!?”
“OMMFNGHH, HMFMFH CMMHFFMM MHH HM HMSFFFH MMFGHGH LKMNHF THMMFHHT~!!?!?!?!” Ruby found herself yelling the same thing, albeit very muffled. Ruby often toyed with her own cunt and jammed as many fingers in as she could, and somehow Yang’s tongue stretched her out just as much as they did.
Yang kissed against Ruby’s drenched rosepetals sweetly and passionately enough to make her feel like she’d fall in love , yet tonguefucked her depths shudder-inducing vigor that pushed her into the deepest pits of lust.
Pretty fucking overwhelming.
Just when Ruby was going to squirt against her sister’s face, she had to pull away! She was getting so used to chowing down on cock, as well!
Yang felt regretful herself, but when your sister’s cheeks that you wanna beat rosy red keep wobbling right in front of you, you kinda have to get to the main event already.
Oh, Ruby. Her big sister already expressed how perfect her dumptruck is earlier, but it couldn’t be overstated. Yang was incredibly protective of Ruby. It was to the point where if someone whistled at Ruby when they walked past, Yang would be trying to start a fight and Ruby would be trying her best to defuse it.
If someone got to take Ruby’s anal virginity before her, she’d be pissed.
Ruby was easily folded around until she was up right, chest-to-chest with Yang and her back to the wall. Her dear sister’s strong hands held firmly onto her cheekfat, their foreheads pressing into each other.
The duo gazed into each other's eyes. They were so much more beautiful all of a sudden. Some shreds of hesitance were still within them, clearly.
“Ruby. D-Do you… really want this? Huff. Your own big sister being y-your first. Heh, a-and probably being your girlfriend after this. Not worried about what people are going to think?”
Ruby smiled at her. “I won’t be able to think if I’m too busy whimpering about you stuffing my ass, sis.”
“I fucking love you, Rubes.”
“I looooouUHHHH YANG YANG YAAAANGGGG~”
Yang nonchalantly pushed it in before Ruby was even done talking. How rude! She tilted her upper half back a little as she began brutally pounding into Ruby’s bottom, treating her like the slut they both knew she wanted to be.
Her sister ’s slut, a walking pocketpussy that would bend over for her without a second thought. Both girls marveled at how amazing it felt. Yang’s dick had never been squeezed so much, but tightness isn't everything! Ruby felt so right. Like she belonged there. Her warmth…
It was comforting, stimulating, incredibly encouraging.
So she might’ve rammed it in much harder and much deeper, the buttclapping probably heard across all of Patch. It wasn’t just that Yang did. She groped the buns she held onto while sucking all over Ruby’s sensitive neck, listening intently to her mewls. Nobody was going to dare catcall Ruby in public with her sister’s lipmarks all over her, a hand latched onto her fat ass as she held her close.
“MMNH.. SHLURRP~!! FHUCKK, I’M GONNA GET DRUNK OFF OF YOU, RUBES..~💕”
Ruby felt so dizzy she may pass out right here. Her thick legs moved to coil themselves around her partner’s frame, just like she saw in all those videos she watched deep into the night. Her hands were digging into Yang’s solid back and dug those nails into her, inflicting some amount of genuine pain into her sister—
Wait.
Yang moved from Ruby’s neck, glaring down at her with reddened eyes and burning hair.
Yang looked so fucking scary. Her new threatening visage with the semblance applied, her big strong arms and her sweat-coated abs… it struck actual fear into Ruby. But fear was only turning her on.
Ruby sunk her teeth into her lips as Yang licked around her own, pausing briefly before kicking those thrusts into overdrive.
PLAP PLAP PLAP PLAP PLAP~🍑💥
Ruby made sure to scrape and stab Yang’s back with her nails harder, which only served as more fuel for even more punishing pounds. Fuck, Yang was putting so much of her aura into it too, each thrust in was knocking the wind out of Ruby. Her buns were undoubtedly red as her hair by now, but she didn’t mind.
That cock swung in so hard and so deep it made a mean bulge in her tummy, her pussy streaming out juices and rumbling like it was really the hole being used up.
Yang couldn’t thrust out very far anymore because of how tight the grip those legs around her waist held. It was a true testament to Ruby’s thirst. Her mouth consistently shoved out gasps and smutty gibberish, but her brain was where she truly ran wild.
‘EHEHEHE, M-MY OWN BIG SISTER’S COOCCCKK !!! Y-YANG IS GONNA BREAK THE FUCKINGGG WALL IF SHE KEEPS SLAMMING INTO MY ASS AGAINST IT! OooUhhHH, I’M G-GONNA MARRY HER! I’M GONNA FUCKING MARRY MY OWN SISTER A-AND SHAKE MY DOUGHY BUTT AT HER WHEN SHE WALKS THROUGH THE DOOR SO SHE CAN MAKE A BIG FAMILY WITH MEEE, YaaAaaAAANNGG~💗💛💗💛’
Outwardly, that last bit was all she could push out. Whining of her sister’s name, over and over and over. If she were a normal person and not a huntress-in-training, these powerfully weighted thrusts might actually hurt. They did, a bit, but in a pleasurable manner.
As much as Yang wanted to scream too, she kept it together for now to tease and tend to Ruby.
“OhhHhH, yessss… you want your big sister’s thick fuckin’ nut lodged in your ass? Hmm? Hmm?” She inquired again with a hard WHAM! inside. “Eyes up here, slut, now in Momma’s cowtits. Look at her when she’s talking to you.”
Yang returned her sister to reality when she gave her cheek a light smack, holding her by the neck after to very lightly choke. It wasn’t actually light at all, but Ruby could thankfully handle it.
Her eyes flickered back towards Yang’s, head tilting as she wore a fuckdrunk expression. Looks like Ruby was the first to get intoxicated over all this.
Her mouth was left so wide open, prompting Yang to spit a fat glob of drivel down in there. Ruby held it on her tongue for a few seconds and shut her mouth to swallow, showing her clean tongue after with a giggle.
Yang couldn’t feel any prouder. “You’re such a good girl, Rubes. C’mon, get ready for the first batch of spunk you’ll get from your new wife. Maybe next time, I’ll push it right into that little pussy of yours~”
Two sisters locked their lips, embraced each other harder and let their primal lust take them over. The sound of water splashing onto the floor was barely audible with the loud tongueslurping and violent smacks of flesh.
Yang made one more push inside, starting a smooch that was much more romantic in intent while filling Ruby up. She wanted to remind her how she genuinely cared, that Ruby was more than just a set of holes to her… which she was too, but again, she really did care!
She was as moved by the gesture as she hoped. The redhead put her all into the embrace of lips, moaning out her sister’s name sweetly, gushing out cuntsquirt all over her abs while being pumped. She wondered if Yang would make her lick it off, or they’d genuinely wash up after. Her hold was loosening…
One, two, three… four– uh. Fifty more smooches and they had finally decided they were done. Drool was pooling and leaking everywhere as they pulled away, minds working overtime to process everything that had just happened.
Yang yanked her cock out painfully to give them both one final rush, and set her sister down, hands on her hips to help her stand.
“... Are– are we really girlfriends n-now, Yang?” Ruby was the first to break the silence, and the one to shift the mood.
Yang answered by pulling her in closer and kissing her forehead, hands raking through the shorter one’s dark locks. “We’re still too young to get married , after all.”
“Y-Yaaaang..!” Ruby whined in embarrassment despite being the one fantasizing about being a housewife.
“Heheh. I’ll be sure to surprise ya with a proposal, babe! But look at you.” She held onto her shoulders, looking past her and down to her behind. “You’ve got a rose butt too, rosebud!”
Ruby rolled her eyes but giggled nonetheless. There was a question that needed to be asked, though.
“Are we going to wash up, or just go for another round?”
Yang shrugged. “Meh, it wouldn’t be nice to just enjoy a niiiice romantic shower with my girl. But,” she paused, smirking as she gave Ruby’s butt a squeeze. Oh no, another pun. “You can still fit some more into this spermbank Rubooty, right~?”
Ruby’s mouth twitched nervously. It sounded nice, but her cheeks and hole were so sore, and her legs were practically burning. A sudden change in Yang’s expression made Ruby realize she took her cunt’s leakage of even more fluids to be an answer.
“Ohohoh? Guess I’m gonna go at it again, then! Let’s see how you handle a full-nelson, babe! Try not to strain your voice screaming!”
Before Ruby knew it, she was already folded into position with Yang’s dicktip throbbing against her rectum.
“Haaah… Y-Yang. You’re going to fuck me even harder than any of your previous partners, aren’t you?”
Yang kissed her neck. “I finally found someone who can take me, I’ve gotta capitalize on that.”
PLAP~! CLAPCLAPCLAPCLAPCLAPCLAP…
“YAAaaANNGG! OoHhnNGGG W-WARN ME NEXT TIIIME~💖 ”
“N-Nope, sorry! Who knows, maybe I’ll even wake ya up one day by teabagging you until you wake up to GARGLE my sweaty nuts!”
Horrifying. Yet erotic.
As she howled like a wolf to the moon, Ruby realized she could hardly wait for what was to come next in her new life with her precious sister and girlfriend.
