Summary
     Yang ropes Ruby into a game of strip poker after a hot day at Beacon.
     Ruby confesses to her sister how she truly feels, and they decide to
     enjoy these new feelings.
“uuuuughaaaaa”
Ruby’s high pitched whine wafted through the air, along with the incredible
heat wave from the window
“Yaaaaaang”
Ruby’s pouting face stuck out from the edge of her bunk bed, her eyes sparkling
with fake tears and a big puppy dog frown. “It’s too hooooot.” she flopped over
onto her back and kicked the air with her bare feet. “why did we have to train
today?”
Ruby looked over her shoulder at her older sister, who was spread eagle on the
cool wooden floor. “Hey don’t blame me!” Yang mumbled “Weiss was the one who
kept saying we’re, ahem” Clearing her throat and adopting a higher pitched
nasally voice “Not keeping up with the class standards bluh bluh bluh”
Making a noise of strain, Yang pulled herself off the floor. Ruby saw her
sister's skin stick to the floor as she struggled to raise herself from the
resting position. “You’re the leader!” Yang shot at her younger sister when she
finally oriented herself upwards “Why did you tell Weiss today was ice cream
day not training day?”
“O-oh well..” Ruby’s head disappeared behind the bed frame slowly “I didn’t
want to be mean….”
“Fiiiiine then.”
Yang showed a sudden spur of energy despite the heat and aforementioned workout
they had to deal with. She jumped from sitting on the ground, planting her feet
under herself and stood to her full height. The movement made Ruby jump, what
made her squeak was when Yang put a foot onto Weiss’ bed, and raised herself to
Ruby’s, putting her face inches from her sister.
“If I have to suffer, so will you.” Yang huffed angrily, her lips making a
comical pouting frown.
“W-what?!” Ruby stuttered out trying to gather her composure. Her sister’s
words hadn’t been what she was focusing on. A feeling of guilt wafted through
her when the first thing she noticed of her sister was how surprisingly shiny
Yang’s lips were. The second feeling was of shame, having known perfectly well
that she has been feeling… strange, around her older sister. Ruby wanted to
come to beacon to learn to be a huntress, but the other reason was to get to
hang around her sister more. Ruby was extremely excited to be in a team with
her, and sharing a room with her was just the same as at home, but it had
constantly been feeling different since a few months ago.
Finally Ruby was able to focus on the conversation. “Wha? I’m already
suffering! I’m sweating too!”
“Do you remember what we used to do when it was too hot back at home?” Yang
mused while she brought her finger level to Ruby’s nose and poked it, forcing
her sister to make an adorable face, like a cat being bopped on the nose.
The immense heat was already making Ruby sweat, but when the answer came to her
head, she felt a new feeling of heat rising to her face
“H-hang around in our underwear?” She stuttered trying to answer her sister.
Yang smirked, hiding her hand behind her back, “Mmmhmmmm…. and the challenge
this time..”
With almost a practiced flourish, Yang produced a set of playing cards from
behind her back.
“Strip poker!”
“What?!” Ruby tried to stammer out a protest “I don’t think tha-”
“Well technically it’s not strip poker..” Yang pondered as she tapped the cards
to her chin.
Ruby let out a sigh of relief. When she placed her hand over her chest she felt
the heartbeat going out of control at the thought of Yang's proposition.
“Cause technically the loser strips, but in this game, the winner gets to take
of clothes, and the loser has to deal with the heat!” The cards slammed down on
the bed, causing the structure to wobble.
“That’s not better!” Ruby protested, feeling her heart beat pick up again, she
was going to have a heart attack because of this. “I’m just going to take a
shower.” She dutifully turned up her nose at her sister.
Yang started pouting again and stuck out her tongue, sometimes people are
surprised that Yang isn’t the younger of the two. “Don’t be a chicken…” She
chastised.
Ruby gasped, making a foul scowl at Yang. “I am not a chicken!”
“Then come oooon” a mischievous smile taunted her younger sister into following
Yang to the floor, with Yang plopping herself down like a child in front of a
rather expensive coffee table Weiss had bought, since nothing else would do for
her.
Once Ruby’s determination to prove her sister wrong had worn off, she
remembered her stomach was in knots. A feeling of embarrassment and shame was
flooding her face, and she felt difficulty in keeping her breath level as Yang
hummed to herself as she shuffled the cards. She knew she shouldn’t be feeling
this way about her sister, She shouldn’t feel flushed and warm when she walked
past Yang showering, she shouldn’t need to promise herself to not peek, She
shouldn’t notice Yang’s lips, and how they are just ever so slightly shiny when
she talks. She shouldn’t notice how soft Yang’s skin looks, and feels, how it
looks covered in sweat after practice, how she smells, Ruby could never pin
what it was, but it was faintly sweet, but thick through her sweat. How most
nights Ruby wanted to curl into Yang’s bed to hold her, and feel her hair and-
The snap of the cards hitting the table made Ruby jump. She saw her sister
making snickering noises behind her cards. With shaky hands, hoping Yang
wouldn’t notice, Ruby quickly snatched her cards off the table, and placed them
in her lap. A 3 of Dust and 5 of Blades. She didn’t play a lot of poker but
Ruby knew this probably wasn’t a good hand.
“Time to see who wins” Yang gloated already sure her hand would win. Flipping
the five cards from the deck, it revealed the Emperor of Crystal, a 6 of dust,
a 10 of blades, a 4 of blades, and a Empress of Dust.
Yang showed her hand, Two 9’s. Ruby had nothing. “Woo!” With energy and
excitement to strip her clothing, which a small part of Ruby she attempted to
ignore extremely hard, agreed with, Yang pulled her scarf off and twirled it in
her hand, tossing it quite an impressive length for a soft piece of cloth to
land on her bed.
Ruby coughed and tried very hard to
stare at her sister’s neck and chest. Especially not stare at her very
impressive bust. Which Ruby saw was also glistening with sweat. After she snuck
a peek and was quickly trying to rub the blush of her face.
“Are you ok sis?” Yang had noticed her sister’s strange actions as she handed
her her cards.
“Nono! I'm fine!” Quickly snatching the cards up and hiding her face. She
didn’t even really look over her cards, as Yang laid out the second batch of
cards.
“Aw shit.” Yang grumbled as she showed a hand of nothing. Ruby looked at her
own hand, realizing, her hand had nothing special either. “I don’t think I win
either..” She said showing her hand.
“Oh… uh..” Yang tapped her chin thoughtfully, like a wise sage. “Let’s both
just strip then.” Yang shrugged, beginning to unbutton her jacket.
Ruby felt her heart jump into her throat every time her sister kept saying the
word strip. Was it a command? If it was she wouldn’t mind.
Trying to distract herself from her thoughts, she hurriedly began to remove her
cape, and tossed it onto the chair behind her.
When she looked back, Yang was had removed her jacket, tossing it to the side.
She was wearing just her yellow tube top. Ruby clenched her fist, failing to
remove her eyes from scanning her sister up and down.
Yang’s hair pooled around her shoulders, where the tips were wet from the sweat
on her skin, her tube top straining to hold Yang’s bust together. Her bare
stomach exposed to the air, and to Ruby to stare at, the faint traces of
muscles and abs under her skin visible.
Ruby’s lip was starting to hurt, she didn’t even notice she was biting it. Yang
tossed the cards to her sister, this time sitting back and fanning her neck and
face, now finally able to cool down a bit. It took all of Ruby’s energy to
focus on her cards, and not the spectacle in front of her.
Surprisingly when Yang laid out the cards, Ruby saw two matches, the 7 and the
5 in her hand both had counterparts on the table.
Nervously presenting her cards alongside her sister, who only had one pair, she
realized she had one.
Ruby looked down at her clothing tho, realizing her skirt and top were one. “H-
hey wait a second!” Ruby protested. “This isn’t fair! I have less clothing than
you!”
Yang gave her sister a confused look. “Rubes, that’s the point of the game. Or
do you enjoy being slow roasted?” She teased her.
“That’s not what I meant!” Ruby huffed angrily.
Yang shrugged and used the cards to fan herself as she waited for her sister to
remove her clothing.
Attempting to keep watching her sister’s movements, her body, her skin and hair
and lips, and try to dig her fingers under her corsets ribbons was proving a
difficult task.
Ruby had to slow down her breathing to finally get to untying the ribbons, she
really hoped that Yang thought she was panting because of the heat and not
because of…. her heat.
It was once the ribbon was loosed and the skirt and top could be removed she
realized she had to stand up. And pull her top down to remove it. In front of
her sister.
Her heart picked up again, and so did her breath. Yang wasn’t paying too much
attention but, she could see her. Ruby felt like the action of what she had to
do was more… oddly sexual.
Pulling at the neck, the top slid open, revealing her bra. As she hooked the
fingers under the top and pulled it down her sister spoke up.
“Aww. Do you still wear that?”
“W-what?” Ruby jumped, realizing her sister was not only looking at her but
noticing her body. Her legs felt faint at the thought and she had to steady
herself.
“You just used to wear that when we were younger I remember it. It was your
favorite cause I picked it out for you.” Yang mused happily with a warm smile.
She looked quite proud of herself for it.
“I just haven’t… grown up a lot.” Ruby covered the cups with her small hands,
even if they were small they still were able to cover the rather small bust she
had.
“Aw, don’t worry Kiddo, I’ve noticed you’ve grown.” Ruby’s cheeks flared red in
response at the fact Yang was paying attention to her breasts. “I was surprised
to see you wearing it because you’ve definitely gone up a cup size, you still
got a ways to go though” Yang cupped her own chest a bit to indicate her point.
Ruby’s face was probably turning the colour of her namesake at this point, and
Yang noticed as she chuckled at her little sister's response.
Ruby just tried to remove her clothing so she didn’t embarrass herself further,
but her clothing stuck around her waist, forcing her to wiggle them back and
forth to slip the top off. This only succeeded in making herself feel like she
was giving a strip dance to her own sister.
Just as they passed her waist, leaving her only in her bra and panties she
quickly sat down again, kicking the clothing away from her.
Ruby always felt that her underwear was a bit more.. mature, than she intended.
Black bra and panties with red lace running over it was always something that
she thought would be worn to seduce someone, but she liked the colours, and
always knew that no one would see it. But now that her own sister had seen her
in it was making her chest pound. At this point she wouldn’t be surprised if
Yang could hear her heart beat. Yang shuffled the deck, making a few chuckles
at Ruby’s embarrassed face and attempt to hide her body. Yang had to admit her
sister was really cute. Not just, like a little sister cute, or like her normal
childlike adorableness. Her sister as a girl was very cute.
Yang just hummed to herself, as she passed the cards.
A flip of the hands, and the cards on the table, showed Yang to win.
“Thank god” she huffed and with relief she stood up. Undoing the belt and
fiddling with the skirt on the back of her shorts, she slipped her thumbs under
the waist line and with a quick motion, dropped them to the floor.
Her ears might have deceived her, but Yang thought she heard both a gasp of air
from her sister and a very soft whine.
For some reason this made her smile. There was something oddly complimentary
about it?
But at the same time it brought up question. She had saw that Ruby was glowing
red the entire time. Yang had assumed it was from the heat. If it wasn’t, then
Ruby was blushing for another reason.
Yang kicked her shorts to the side and sat down, this time, on the side of the
table and not the opposite end.
“Floors too hot over there.” She whined out loud.
That was one of the reasons. Another was because, the effect she’d been having
on her sister was…. intriguing.
She didn’t want to do anything with her sister, that would be wrong wouldn’t
it?
Technically they are only half sisters. That’s not really wrong right?
It wasn’t wrong to find your only half sister cute. Or to find her peeking at
your body adorable. Or to feel something… something warm in your chest when you
saw her in the same underwear you gave her. Was it pride?
Yang mused over all these ideas in her head as she shuffled the cards.
She forgot to pay attention to her sister.
Until she heard a soft panting beside her.
With a questioning noise Yang looked up from the cards.
Ruby was on all fours, crawling towards her. Her face looked like one of those
baby strawberries. Small, rounded, soft, and red.
Yang felt Ruby’s breath on her skin, causing a shiver to run down her spine.
She didn’t notice how close she had gotten. Her silver, childlike eyes looked
clouded over.
“Ruby?” Yang said one word before she was knocked over.
 
Ruby had pushed Yang down by her shoulders, pushing and holding her down with
her weight. This would hardly be enough to hold Yang down, but the sudden
surprise and not wanting to hurt her sister made it impossible to react.
“Ruby what are y-?!”
 
Yang’s words were interrupted as she felt Ruby’s lips touch hers, forcing her
mouth closed. Yang’s eyes shot wide with surprise, trying to say a word of
protest, but her sister's mouth muffling any noise.
Ruby’s hands moved from Yang’s shoulders to cup her face, like one would a
lover. It was Yang’s turn to feel her face burn up, as her sister kept the kiss
going, only ever breaking contact for a second to breath and then kiss Yang
again from a new angle.
Yang could protest, say something, push her away. Yang could have done a lot of
things.
But for some reason, all she could do was grip onto Ruby’s arms, her own hands
large enough to wrap around them. Every time Ruby pulled away, her breathing
was labored, and when she came back to kiss again, it felt.. sloppy. Yang could
feel her sister’s tongue make contact with her lips each time she pulled back
in.
It felt like her sister’s tongue had a spark. it touched and she felt shocks
run through her body, ending between her legs.
When she felt it she had to combat pleasure and shame.
She had to pull back, it felt wrong but good.
Yang stuttered every time Ruby pulled back, she tried to say her name, but she
couldn’t get the words out or Ruby’s tongue stopped her.
Yang pushed on her sister’s arms, forcing her mouth off of hers. “R-ruby stop!”
 
Ruby was frozen. A look of horror was on her face. Unable to move in her
sister’s grip she had to fight her panting breath, her chest rising and
falling, she felt her entire body shaking in her sister’s grip. Yang was able
to pull herself up to a sitting position in front of her.
When Ruby saw her face it finally sank in what she just did.
She tried to say something, an excuse? A reason? An apology?
When it reached her throat it got cut off. Ruby stuttered 3 times just trying
to say “I” and kept choking on her words.
Finally she couldn’t fight it, feeling her eyes beginning to water, she could
only sob, and cover her face so she wouldn’t see the look on Yang’s face.
“I’m so sorry..” Ruby didn’t know if Yang could even hear her, her words broken
up by sobs and muffled by her hands. “I’m so so sorry, I’m sorry please..”
“Ruby…” Yang had a lot of emotions she had to deal with, but first and foremost
she had one job.
Yang wrapped her arms around Ruby’s small frame, ignoring what just happen,
ignoring the body heat, ignoring anything else besides her knowledge that her
sister was hurting. Yang held Ruby close, resting her head on Ruby’s shoulder,
as close as she could get to her as Ruby curled up.
Yang made comforting noises, petting her sister’s hair and whispering, telling
her it would be ok.
Yang had no harsh words for her.
It could have been 10 minutes, or 5, or 20. Yang didn’t count, she just held
her sister close, she could feel that Ruby wanted to turn away, run away from a
problem. She was going to be here to help.
She couldn’t pinpoint when Ruby had stopped crying, but she felt Ruby remove
her hands from her place and wrap them around her older sister, tucking her
face into Yang’s shoulder like a small child.
“Ruby…” Yang spoke softly, and evenly. There was no blame in her voice.
A muffled voice responded, but she couldn't make out the words. Making a gentle
questioning noise, Yang moved her shoulder back, letting Ruby’s face be exposed
behind her hair.
“Please don’t hate me…”
The words felt like weights on Yang’s heart, and she quickly squeezed Ruby
closer to her.
“I could never hate you. I promise.”
Ruby sniffled quietly, the room became silent again for a few minutes. Yang was
the one to break the silence again.
“I’m not mad. Ok? but... I do need to know what just happened.” Yang didn’t
want to push Ruby away, she wanted to hug her close and never let go, but she
needed to look her in the face.
Ruby’s face had tear streaks on her cheeks, Yang quickly but softly used her
thumb to cup her sister's face, and wipe away the tears, but her face was still
sad. Ruby quietly nodded.
“So please tell me?”
Ruby’s sigh was shaky trying to steady herself after having a mini breakdown.
“Ok.” Yang had a very weary smile but she kept her hands on her sister's arms,
hoping it would reassure her. “When did you start… feeling like this?”
“A few months ago.” Ruby’s voice was barely more than a whisper, like a scared
child admitting they had stolen cookies.
“Okay.” Yang repeated again, trying to take the conversation slowly. “Are you
just… lonely?” Yang couldn’t find a good word for what she wanted to express.
She might have found the right one, since Ruby’s shoulders quivered at the
words. She nodded.
“When you left…” Yang’s heart broke again, hearing those words, and her sister
sounding like she was going to cry. “I was lonely. And I couldn’t sleep. And I
just wanted you back. And when I could finally go to beacon, I knew I could be
a huntress… I always wanted to. But I would get to see you again. And I was so
happy when we were on a team. And you looked so proud of me. And I wanted to
see you look happy more so so badly…”
Yang saw her sister’s hands shaking as she fought back sobs. She softly let her
fingers float down Ruby’s arms, and cupped her little sister's hands inside of
hers. She squeezed them gently, not wanting to say a word to interrupt her, but
telling her that she was here.
“And when we got to sleep in a room together, it’d be just like back at home.
And I remembered that sometimes if I had a bad dream, or got lonely, I could
crawl into your bed. And I just…. I couldn’t sleep and I wanted to get to lay
down beside you and hold you. But I felt like I wasn’t allowed. Like it wasn’t
ok. Why…” Ruby’s voice cracked, and she had to stop her sentence to hold back
tears. Ruby’s hands gripped onto Yang’s tightly, she pulled on them and placed
her face in her sister’s palms. She wanted to feel as close to Yang as she
could. “Why can’t I love my big sister?” Ruby couldn’t hold back and began
sobbing again, gripping Yang’s hands, she never wanted to let go again. Yang
could feel her sister’s tears, as they glided down her face to touch her
fingertips.
Yang didn’t realize she had started to cry too. “Ruby… I love you too, and-”
“No!” Ruby cut off her sister. She pulled Yang’s hand away from her face, and
locked her hands around it. Ruby knew Yang’s hand was much bigger than hers and
even both her hands only held onto the palm, but she gripped it tight, holding
it between them. Ruby’s eyes, shining from tears, stared into her sister’s,
trying desperately to get her to understand. “No Yang. I love you. I do. You
are the nicest person to me. You always make me happy. I want to sleep next to
you and wake up and see you and you have the best smile and you’re so pretty
and I just... “ Ruby couldn’t find the words, and at the same time had too many
to describe Yang. Her sister. But something so much more than her Sister. “Why
does it feel wrong?” Her eyesight broke away from her sister’s, unable to keep
eye contact. Every time she felt the flutter in her chest, the happiness and
beams in her head. She felt sick to her stomach. What she was doing was wrong.
But it felt like the best feeling in the world. How could she ever go back to
before once she knew what this felt like. What her sister felt like.
 
The silence felt like forever. Like a prison sentence of a million years was
condemned on Ruby, she was to face shame and broken hearts for her crimes.
Yang’s fingers twitched. And then she reached out, sliding her hands out of
Ruby’s grip, and softly placing themselves on Ruby’s cheeks. The softest of
touches, she tilted Ruby’s head back up, making eye contact with her. Ruby saw
the tears on Yang’s cheeks, as they fell onto her lap.
“Nobody decides what’s wrong besides us.”
Ruby was confused by the words. So confused, she didn’t even register the
feeling of Yang’s lips on hers. By the time she recognized the feeling, Yang
had pulled back.
Ruby could feel wetness on her lips, but, the salty taste made her realize it
was from Yang’s tears.
“And I know what I decided.” Yang, despite still having tears in her eyes,
cracked her signature goofy smile.
“w-what?” Ruby’s mind was blank, unable to understand what was happening.
The sudden pull, slamming her into a tight bear hug from her sister didn’t
help, and neither did the possible whiplash Yang just gave her.
“I shouldn’t have left you behind like that!” Yang’s voice was stern, but
directed at herself this time. “I’m so sorry I did that to you Ruby. I won’t, I
won’t I won’t I won’t. Im not going to leave you behind again.”
“Y-yang” Ruby’s voice wheezed. She swore, if she could even breath to do it,
she felt her ribs cracking under Yang’s hug.
“Oh! Sorry!” Yang let go of her sister, Ruby gasping as air returned to her un-
constricted lungs.
After Ruby could breath, and Yang stopped fussing over her, Ruby finally looked
her sister in the eyes. She brought a hand up, and felt her own lips, the very
faint feeling of moisture was still on them.
“You… you kissed me?” The realization finally sunk in.
Yang kept her huge grin plastered on her face, never letting it drop. She
cupped Ruby’s hands, and held the between the two of them.
“You love me… So much. I thought what you did was just… A moment of lust. But
you have so much love for me. And it just… It made me feel something. Like a
little fire inside my chest. You are the best person I’ve met Ruby. You’re so
nice, and innocent, and sweet. I always love to find ways to make you laugh.
and it makes me happy when you’re happy. And when I knew that you loved me so
much, I knew it. I just knew it inside that you may be my sister. But I really
really love you too.”
The more Ruby let what her sister was saying sink in the more she realized what
Yang was implying.
By the end of it, Ruby’s eyes had filled with tears.
“W-wait Ruby no..” Yang panicked as Ruby let out a singular high pitched whine.
Ruby flung her arms around Yang’s neck and toppled on top of her. Yang let out
a hearty “oof!” after being crushed by her crying sister, again. Before Yang
could protest Ruby began planting kisses along Yang’s cheek and mouth and nose.
“Hey!” Yang playfully protested against her little sister’s assault of love.
Yang was sure she heard her sister repeating “thank you” after every kiss and
was more just impressed she was able to talk that fast even when she wasn’t
stuffed with sugar. Ruby wiggled her legs around her sister, ensnaring her in a
love hug of death, and making sure to not let go.Yang couldn’t help but laugh,
and gently pet the back of her sister’s head softly.
When Ruby pulled away from Yang, their skin stuck to each other, but neither
could figure out if they were warm from the heat outside, or from each other.
After feeling the sensation, Ruby looked down, during everything that happened
she had completely forgot her and her sister were sitting in their underwear.
"O-oh" Ruby hesitantly crossed her arms in front of her, but with most of her
body exposed she couldn't hide very much.
"Aww" Whether Ruby was her sister or something more, Yang still couldn't get
over how adorable she was when embarrassed. Yang gripped her sister's wrists
and moved her arms out of the way, much to Ruby's whining. "You don't have to
hide. You were always really cute."
Ruby couldn't cover herself back up, but her skin tried to by burning red with
embarrassment. "Speaking of thaaaaaat." Yang's mischievous smile poked fun of
Ruby, as she leaned in closer to her sister's face.
Ruby stuttered trying to say something until Yang's face was inches from her's.
"It was your tuuuuurn!"
Ruby flinched as one of Yang's fingers gently tapped against her nose. She was
so distracted by it and her sister's breath on her neck, she hadn't felt Yang's
hand creeping up her back.
Digging a finger under the lock on Ruby’s bra, Yang flicked her finger
expertly, unlocking it.
The shoulder straps slipped off from the elastics of the bra, and slipped down
Ruby’s arms, the cups falling and exposing her breasts.
Ruby froze up, not knowing if she should cover herself or not. Yang ignored her
sisters ever increasing blushing and levels of embarrassment, turning her
attention to her prize.
“Oooh~” Yang cooed softly. Her hand pressed against Ruby’s breast, causing it
to squish under her pressure. “Yang!” Ruby jumped at feeling her sister's hand.
Yang’s hand was warm, very very warm, but the sweat made a shiver run down her
spine.
Yang’s thumb rubbed across Ruby’s skin, flicking softly against Ruby’s pink
nipple. It hardened against her touch. Yang’s fascination continued as she let
go of Ruby’s breast, and pinched the nipple suddenly between her thumb and
finger. Testing it she gave it a pull.
Ruby’s back arched, as she let out a small whine. Her eyes were shut,
concentrating on not letting her voice out. With another pull, Ruby felt shocks
of pleasure from her chest, and she couldn’t hold back. A soft moan escaped,
panting hard, she tried to gain balance by leaning against her sister.
“You are so cute it should be illegal.” Yang giggled, still keeping her
sister’s nipple in a vice grip.
Ruby’s legs were shaking slightly, trying to pull herself back just caused Yang
to pull on her breasts again, and another shock, like static electricity of
pleasure made her jump again.
“That’s not fai- AH!” Ruby’s protests were cut short by Yang slapping a rather
firm hand onto her rump. Yang gave it a few test squeezes. “Wow~ It’s actually
pretty soft.” Yang’s eyes were wide as she kept groping her sister’s ass.
Yang could feel Ruby’s hot breath as she panted against her neck. Yang let out
a giggle as she got an idea. pulling simultaneously on Ruby’s nipple and
squeezing her ass, she let both slip from her grasp, pleased at the faintest
jiggle they both made, and at the noise her sister just made.
“Here~” Yang smirked as she pushed her sister to sit upright, and crossing her
arms in front of her, she took hold of her tube top, and pulled it over her
head.
Yang could have sworn she saw stars shining in her sister’s eyes as she stared
at Yang’s breasts. They were about twice the size of Ruby, who she would have
guessed was just pushing a B cup. Yang could fill her D cup with much of her
own satisfaction. Yang cupped her hands under her breasts and gave them a light
squeeze, shooting a wink towards her sister. Ruby scooted forward, she gripped
onto Yang’s thighs before leaning forward and wrapping her mouth around her
sister’s breast. She quickly went to work and suckled on her nipples, lapping
her tongue against the sensitive nub. “Unf~” Yang bit her lip enjoying her
sister's enthusiasm. Ruby let go of her sister’s tit and let it drop from her
mouth, and turned her attention to the other one giving it just as much love as
the last. Yang giggled slightly seeing her Ruby so excited and pet her hair as
Ruby pleased her.
Yang felt warmth spread from her breasts into the rest of her body, and soon
her cunt felt on fire. Not wanting to hold back anymore, Yang reached between
her legs and began rubbing herself through her underwear. With Ruby latched
onto her nipple and playing with herself Yang began moaning like a cat in heat.
Ruby noted her sister’s enjoyment and began being rougher, pinching her nipples
and nibbling on her sensitive skin. Ruby’s fangs left small love bites on the
older girl's chest and shoulders. Yang’s hand, shaking slightly, grabbed
Ruby’s. She could tell her sister’s fingers were wet, and slowly Yang pushed
Ruby’s hand against her panties. Yang’s lace panties were soaked and becoming
see through from her juices, Ruby gazed transfixed on her sister’s lust,
following the outline of her lips through her panties and digging her fingers
into the material to rub her. Her thumb found a small hard button and she
gently played with it, eliciting sharp jerks from her sister’s legs. Knowing
she had found her clit, Ruby dug in and began playing with it roughly. Yang’s
head shot back as she moaned loudly into the empty room. “Holy fuck Ruby!”
Yang’s voice was shaking with her body, her voice breaking slightly trying to
keep control. Yang grabbed her panties and roughly tore them off, throwing them
so hard they hit the wall on the opposite side of the room. Ruby could see her
handy work first hand, Yang’s pussy was red and wet, her lips leaking juices
already forming a small pool between her older sister’s legs. Ruby could even
see Yang’s pink clit easily as it ached to be touched.
“I’ve… I’ve never gotten this far before.” Ruby gazed at her sister with
longing and nervousness. “You’ve done this with someone else?” Yang’s breath
was ragged but she was truly curious about her Sister’s love life. She had
always pushed for Ruby to find someone special. She never would have thought it
would have been herself. “N-No!” Ruby exclaimed loudly in her embarrassment.
She cleared her throat trying to control herself. “I-I never got this far in
my… books.” The young girl admitted. She muttered something quietly afterwards.
“You what?” Her ears were buzzing slightly from all the blood in her head and
couldn’t make out what her sister said.
“I always… finished too fast.” Ruby admitted. She turned red again as Yang
giggled, and wondered if she would pass out if she kept blushing like this.
Yang took Ruby’s hand and placed it on her palm. “Here.” Yang pulled on her
sister’s arm, and placed the girl's delicate fingers directly against her
folds. “I’ll show you.”
Ruby looked down at her hand and her sister pushed against Ruby’s fingers, and
she entered her sister. Yang let out a loud sigh of pleasure and Ruby took the
chance to take over. Ruby had never fingered herself, she prefered to just play
with her clit until she came. From her Sister’s twitches and moans, she much
preferred the sensation of something inside of her.
Mimicking what Yang had demonstrated, Ruby flexed her fingers, pushing and
pulling them in and out of her sister slowly. She picked up the pace and
started using her wrist to begin a thrusting motion. Ruby knew her fingers were
much shorter than Yang’s constant muttering told her she was doing a good job.
“Fuck…. Don’t stop.” Yang grabbed her sister’s hair and pulled their heads
closer. Ruby felt the blonde's breath against the top of her head, coming in
hot short rugged breaths.
Ruby’s wrist hurt slightly but she picked up the pace, pushing her fingers into
her sister’s pussy and a wet noise could be heard coming from between the
blonde’s legs. An embarrassing lewd noise but it made her keep going. Yang’s
hips began shaking as she tried to lift them off the ground.
“Holy fuck!” Yang gritted her teeth and moaned through them, her hips jerking
slightly trying to push against Ruby’s hand. “Ruby I’m gonna cum… Fuck I’m
gonna… I’m…”
Yang’s voice trailed off and was replaced by a hiss as she sucked in air as her
entire body started shaking. Ruby didn’t slow down her finger’s and in her
orgasm Yang couldn’t tell her to stop. Yang let out a loud moan as her body
convulsed in pleasure. Ruby felt Yang’s cunt tighten on her fingers before her
sister started squirting. Her juices landing on Ruby’s legs and the floor
between them. The liquid pooled between her sister’s legs into a large puddle
as Yang collapsed onto her back and laid there with her arms and legs spread.
Ruby pulled her fingers out of the warm hole and looked at the liquid on them.
She gave it a lick, finding it incredibly salty, normally she would call it
gross but something about it, the smell, or the feeling of it made her stick
her fingers in her mouth and lick them clean.
Yang could barely control her breathing as she tried to calm herself down. It
was the first time in her life she had an orgasm that intense, nor had she ever
squirted. A little embarrassed to have done that in front of Ruby she closed
her legs, but the pool beneath her was still obvious to what she had just done.
Raising onto her elbows slowly, she looked at Ruby who she find waiting for her
to recover. “Ruby you’re…. You should have told me you could use your fingers
like that.” Yang weakly laughed as Ruby hid her face in her hands. “I’ve never
done that before! I didn’t even know I could.” She mumbled into her hands.
Yang steadied herself before slowly getting to her feet, trying to hide her
shaky knees. “Ok Rewbs.” Yang said as she planted her hands on her hips. “It’s
your turn!”
Ruby uncovered her face to look up at her sister. “W-wait do you mean you’re
gonna…” Ruby trailed off and looked at the floor, where her and Yang had left a
mess. Yang grabbed her clothing and tossed it on the puddle to, hopefully,
cover their tracks. “Nope! You’re getting something better.”
Without saying anything else Yang grabbed her sister by the wrist and walked
around the couch, pulling the girl off the ground and making her march behind
her. Ruby didn’t realize until she was forced to her feet how wet she was. Some
of the juices running down her legs belonged to Yang, but she knew most of it
was hers.
Yang pulled on her sister’s wrist, pulling her close, then in one arm grabbed
the girl around the waist and lifted her off the ground and tossed her onto the
bed. She let out a yelp as she hit the bedsprings and bounced. “W-what are we
gonna do Sis?”
Yang’s heart skipped a beat seeing her cute sister looking so defenseless on
the bed. Yang crawled onto the bed and slowly crawled forward on her hands and
knees. She licked her lips as she got closer and Ruby’s heart was running a
mile a minute in her chest. When she reached her sister, Yang placed her chin
on the younger girl's knees and smiled deviously. She ran her fingers up and
down her sister’s soft thighs and smirked at the small twitches she elicited
from the poor girl. She hooked her fingers onto Ruby’s panties and pulled them
off smoothly. Ruby pushed her legs together in surprise. Yang gave her calves a
kiss, giving her trademark wink to the dark haired girl, and Ruby opened her
legs slowly as she blushed.
Throwing the girls panties over the side of the bed, she wiggled herself
between Ruby’s legs.
“Holy shit!” Yang snickered in surprise and made Ruby blush heavily. “W-what!?”
Ruby tried to close her legs, embarrassed something was wrong, but Yang’s arms
were stronger then her leg and kept them open. “I thought I was bad, but you’re
a damn faucet sis!” Yang bit her lip seeing the massive amount of juice her
sister was leaking. Her entire inner thighs were wet and her pussy was pink and
soaked. Yang took a moment to admire her sister’s pussy, surprised at the
adorable colour. Her lips were small unlike her own, and her clit was a darker
shade of red.
Licking her lips she decided not to tease the poor girl anymore. Yang dove face
first in between the younger girl’s thighs and dragged her tongue across the
girl’s pussy lips slowly.
“Ah!” Ruby yelped in surprise but it turned into a drawn out moan as Yang went
in again, this time pushing her tongue deeper. Yang flicked her tongue against
Ruby’s clit, each time eliciting a high pitched squeak and for Ruby to dig her
fingers into Yang’s hair. Yang wrapped her arm around Ruby’s thigh and used her
now free hand to play with Ruby’s button, making small circles around the
sensitive spot. Ruby’s legs lifted off the mattress as she moaned from the
feeling, her body shaking. Now that she could use her hand, Yang used her
tongue to push into her sister’s hole and poke at her folds. Yang had a short
tongue but it’s wideness help fill Ruby with a sensation she had never felt
before. She was being filled by a new feeling and having her clit expertly
played with, soon her brain began going blank from the pleasure. Ruby knew she
was trying to say something but her words just became mush in her mouth and
turned to moans.
 
The only thing her brain could finally put together and she began panting “Big
sis… Big siiiiis…” Ruby moaned as her body started to convulse. Yang flicked
her clit mercilessly as she ate her out. “YaaaaaaNNNG!” Ruby squealed the words
as her body shook with her orgasm. Her thighs locked together and kept Yang
trapped between them as she rolled her hips with the waves of pleasure.
Ruby felt like there was no air in her lungs until she finally could breath,
and her body let her go. Her limbs went limp as Yang raised from between her
thighs gasping for air. Her face was wet as she panted, a line of saliva still
connecting them. She wiped her face clean and sat up, looking at Ruby who’s
eyes were still out of focus. Yang crawled next to her and layed down next to
her sister. She wrapped her arms around Ruby’s stomach and pulled her close,
becoming the big spoon. They lay on the bed naked, covered in sweat and slowing
regaining their senses.
“I love you Ruby.” Yang whispered into her hair. “I-I love you too Yang.” Ruby
turned over slowly, able to look her sister in the eyes. “Thank you.” Ruby said
quietly as she buried herself into her sister’s chest, hiding away from the
world.
“This is for us.” Yang said softly, Ruby was confused at the words and looked
upwards at her. “Each other. We can just… have each other. And we’ll figure the
rest out.”
It dawned on Ruby what the girl was trying to say.
Tears welled in her eyes as she buried herself in her sister’s chest. This time
instead of hiding, wanting to embrace the person that meant the most to her.
“Thank you Yang.”
“Any time lil sis.” Yang kissed the top of the girls head and hugged her
tightly. “Anything for you.”
