Work Text:
Yang is nine when she finds out how nice it feels to have something rub against her privates. She’s straddling Ruby’s waist, pinning her younger sister down to try to draw something on her forehead, when Ruby starts squirming in just the right way. The sensation is like nothing she’s ever experienced, a sharp pleasure that makes her gasp followed by warmth spreading deep inside her.
The momentary distraction is enough for Ruby to wriggle her way out from under Yang, and Yang forgets about that strange feeling in the ensuing chase. It’s not until that night, as she’s drifting off to sleep, that she starts thinking about it again. She lazily reaches her hand down between her legs and starts rubbing up and down, trying to imitate the movements Ruby had been making.
It works! The strange feeling is back, and Yang is wide awake now. She doesn’t know why, but her heart is pounding like a drum in her chest.
To better mimic the position she was in with Ruby, she sits up straight and grabs her pillow to wrap her legs around. She makes sure to press it right up against her privates and is rewarded when a thrill shoots up her body at the contact.
Since the pillow can’t move on its own, she starts rocking herself back and forth, grinding herself against it. She’s panting before long, though it’s hard to say if it’s from the physical exertion or from the way the pillow is making her feel.
It’s like there’s an ocean of pleasure being held back by a small dam, and the more she rocks her hips, the more leaks spring in the dam. It won’t be long before the whole thing bursts. She doesn’t know what will happen when it does, but everything inside her is screaming for her to find out.
She rocks faster, an urgency in her movements now. Small, childish moans are intermingled with her gasps, but she’s too absorbed in her activity to care if anyone can hear. She can feel her body building up to something, some grand crescendo that everything she’s felt so far will pale in comparison to.
When it finally happens, she can’t help crying out in surprise. Her whole body tenses, and she squeezes the pillow between her legs like a vice. There’s a singular moment, when she sees white and feels like the whole world’s stopped, that she thinks she’s died. Then the dam breaks, and her body is flooded with an indescribable pleasure. She lies down face-first and basks in it. She doesn’t think she could move if she wanted to. Her legs are shaking, and her privates are throbbing, sending a dull pleasure emanating out in waves.
That’s how she drifts off to sleep, with her pillow still between her legs and the echoes of her first orgasm ringing inside her.
Yang is a good big sister, so she naturally has to share what she discovered last night with Ruby. She sneaks into Ruby’s room early in the morning, wanting to show her before Taiyang wakes up. She doesn’t know why, but she doesn’t want their dad to know about this.
“Ruby!” she hisses as she pulls the covers off her. “Wake up!”
With a flash of rose petals, the covers are back on top of Ruby. “Don’t wanna,” she whines.
“This is something fun, I promise!”
A pair of sleepy eyes peer out at Yang from the bundle of blankets. “What is it?”
“It’s something that will make you feel really good. All you need is a pillow!” Yang lifts up the one she brought with her from her room.
There’s curiosity in Ruby’s eyes now, but she makes no movement to leave her cocoon of warmth.
Yang decides a demonstration is in order. She sets the pillow down on the ground and sits on top of it, wrapping her legs around it just like last night. “You just have to sit like this and move back and forth really fast. It feels so good.”
Yang’s heart is already racing in anticipation, but Ruby doesn’t seem convinced. “Why does it feel good?”
Yang shrugs. “I don’t know. I think it’s ‘cuz it rubs on your privates though.”
Before Ruby can ask any more questions, Yang starts rocking back and forth on her pillow. Something about having Ruby watch while she does this is making it feel even better, and she’s gasping and moaning before long.
“Is it hurting?” Ruby asks. She’s sitting up now, looking at Yang with concern. “Why do you sound like that?”
Yang shakes her head. “Feels good,” she says between breaths. She closes her eyes for a moment, reveling in the intensity of the feeling, and when she opens them, she sees that Ruby has finally joined in, rocking back on forth on her own pillow.
“Do you like it?” Yang asks.
“It’s not working,” Ruby says with a pout. “Are you tricking me?”
“No! I’m telling the truth.” Yang reluctantly untangles herself from her pillow and gets up to help her little sister. As far as she can tell, Ruby’s doing the same thing Yang was, but it’s clearly not having the same effect. “Maybe you need to take off your pants?”
Ruby’s face turns red. “No way! I’m not doing that! You’re just trying to trick me so you can make fun of me.”
“No I’m not! I think it’ll work better if the pillow can touch your privates.”
Ruby shakes her head, a stubborn set to her jaw. “No.”
Yang sighs. “Fine.” She hooks her thumbs in her pajama pants and pulls them down, taking her underwear with them. “See? I did it first.”
Ruby starts giggling, and Yang suddenly feels self-conscious. “What’re you laughing at?”
“You peed yourself!” Ruby points to Yang’s privates, and sure enough, her bare mound is glistening.
Yang feels herself blush as she checks her underwear and sees the damp spot there. “I didn’t—it just—I didn’t notice—”
“Maybe it felt so good it made you pee?” Ruby asks. “Like that time Mom laughed until she peed herself?”
Yang laughs, the memory washing away her embarrassment. “Yeah, just like that! I told you it felt good.”
“Okay, I believe you.” With that, Ruby reaches down and slips off her pants as well.
The girls can’t help giggling as they stand in front of each other with their privates showing. They’ve seen each other naked before, of course, but not since they were little. This feels different somehow. Naughtier, but also exciting in a way.
They both get back on their pillow and resume their motions from before. Yang realizes right away that she was correct—it feels so much better when the pillow is directly touching her privates. She doesn’t want to ever stop, but Ruby clearly doesn’t feel the same way.
“It’s still not working!” Ruby says as she flops back on the bed. “I can’t do it right.”
Yang feels bad. She just wants Ruby to be able to feel as amazing as she had last night, but it seems like the pillow isn’t doing the trick. Maybe there’s something else she could use.
That’s when Yang gets an idea. “I think I can help,” she says as she gets up and walks to the side of Ruby’s bed. Ruby has her legs draped over the edge, her privates face-up for the world to see.
Yang is thinking about last night when she’d touched her privates with her hand. That had felt good too, so if she just reaches out…
Before she can reconsider, Yang sticks her hand between Ruby’s legs.
“Hey!” Ruby cries out.
“Wait a sec. I just wanna try something.”
Yang starts rubbing her hand up and down Ruby’s slit, pressing against it just like how the pillow does.
“Oh!” Ruby gasps and squeezes her legs together around Yang’s hand. “That tickles!”
“But it feels good, right?”
Ruby nods. “Uh huh.”
Yang smiles, happy that Ruby’s finally getting to experience this feeling. “I’m gonna keep rubbing, okay?”
When Ruby nods, Yang resumes her motions. It’s strange, but touching Ruby is giving Yang a similar sensation in her stomach to the one she gets from rubbing on the pillow. It’s like knowing that she’s making Ruby feel good is making herself feel good as well.
Ruby is panting now, even though she gets to sit still while Yang does all the work. She bites her lip but can’t stop the moan from coming out. It makes her giggle and say, “I can’t stop making weird noises.”
“That means it’s working,” Yang says with a smile. She enjoys the way Ruby is starting to squirm beneath her fingers.
Suddenly, Ruby’s movements cause Yang’s finger to slip inside her slit. She brushes something there that makes Ruby’s hip buck wildly.
“Sorry! I didn’t mean to!” Yang says as she quickly pulls back her hand.
“No! Don’t stop,” Ruby pleads. “That felt really good.”
“Oh. Okay.” Yang returns her hand to her sister’s privates and slips a finger back in her slit. She notices that Ruby must have peed a little too, because moisture is helping her finger glide effortlessly along her slit. Surprisingly, she doesn’t find it gross at all. It just makes that feeling in her stomach all the more intense.
When she gets to the top of Ruby’s slit, Yang brushes against that bump she'd felt before. Once again, Ruby’s reaction is immediate, her hips rising up as she squeezes her legs around Yang’s hand, trapping her there.
Taking that as a sign that she’s doing something right, Yang starts focusing all her attention on that little bump. Every time she so much as brushes it, Ruby gasps out loud. Yang doesn’t want to hurt her, so she makes sure to be as gentle as she can as she circles around it.
“I feel really funny,” Ruby says between moans.
“I think it’s gonna happen soon,” Yang tells her.
“What’s gonna—” Ruby starts before Yang brushes the bump again and her words are drowned out in a moan.
Yang picks up the speed, wanting Ruby to feel that part as soon as possible. The room is filled with the sounds of Ruby’s moans and squeaks, and there’s a strange musky smell in the air. Both are making Yang’s heart race for some reason.
Yang knows when it happens. Ruby lets out a long, drawn-out moan as she squeezes her legs together so tight that Yang loses feeling in her hand. They stay like that for a while, and It seems like an eternity has passed before Ruby’s body starts relaxing and Yang’s hand is free. Even now, Yang can see Ruby’s legs are still twitching.
Ruby smiles up at Yang with a look of wonder on her face. “What was that?
“I don’t know, but it’s amazing, right?”
“Yeah! Can we do it again later?”
“Of course,” Yang says as her stomach does a weird flip. Her words make Ruby smile even wider. She looks as excited as she does when Taiyang brings home fresh cookies from the bakery.
“Next time I get to touch you too, okay?” Ruby asks.
Yang swears she feels her privates throb at the thought. “I’d like that.”
Ruby looks like she’s starting to drift off again, so Yang decides it’s time to go back to her room. She bends to help Ruby pull her pants back up, but before she gets them all the way, she’s seized by a mischievous impulse and leans forward and plants a kiss right on Ruby’s slit.
“Love you, sis,” she says.
“Love you too,” Ruby mumbles sleepily.
As Yang gets dressed and slips quietly out of Ruby’s room, she thinks there’s something different about their relationship now. She can’t explain it, but she feels closer than ever to Ruby. As she gets in bed and slides a hand down her pants, she can’t help hoping that they’ll discover new ways to become even closer.
For now, though, this is perfect.
