As Rachel passed by her sister’s room, an odd sound she couldn’t place caught her ear through the closed door. It was something like a soft, electric hum. Lucy didn’t like to be bothered when her door was closed, so Rachel crept quietly to it and placed her ear against the thin wood, hoping that Lucy wouldn’t catch her. Her older sister’s wrath was not something she liked to bring down on herself. It wasn’t that Lucy was mean. Not exactly. She just had this way of making Rachel feel small and silly, which she guessed she was, and the way she did it gave Rachel a funny feeling, like an excited buzz that she’d never quite been able to understand.
Rachel’s heart thudded loudly in her ears as she leaned to the door, inwardly cursing her own curiosity. She just couldn’t help it. She wanted to know everything about everything, and it had gotten her into some trouble from time to time. Especially with Lucy. Sometimes, she snuck into her older sister’s room to snoop. It wasn’t malicious. There was nothing in particular that she was looking for. She was, simply, curious. The older girl knew so much more. She had experience. Rachel just liked to know what it was that older girls did, thought about and liked. Her mother kept her so in the dark about everything, even going so far as to review the library books she checked out for anything too naughty.
"You're not going to be like Lucy," she'd say, but never went into detail about what that meant.
Ear pressed to the door, Rachel could make out the muffled sound of the electric hum, as well as another sound, softer, feminine, like that of a hot sigh of breathy pleasure. What was Lucy doing? For a moment, she wondered if her sister was okay. Maybe she was in pain. Perhaps something was wrong. Experimentally, her hands trembling, Rachel touched the door handle and felt it give. It was unlocked. Lucy, likely, thought she was alone in the house. Normally, their mother would have driven sheltered Rachel to the library and dropped her off for a few hours on a Saturday. Today, though, her mother had been called into work, which left Rachel at home.
She carefully eased the door handle down, moving very slowly and deliberately. It wasn’t that she wanted to spy, she told herself, she was just curious. What were those sounds? The handle clicked, more loudly than Rachel would have hoped and she winced, her hand resting on the handle as she waited to see if Lucy had noticed the sound. Seconds passed as she waited, her blood rushing in her ears and a feeling of perverse excitement coursing through her. Nothing happened. The humming continued. The soft moans and whimpers became a bit louder.
Carefully, with agonizing slowness, Rachel let the handle up and let the door crack open. She gave herself just the barest of cracks to look through, and what she saw didn’t really make sense. She tried to puzzle it out. Lucy lay on her bed, her back propped up against a small stack of pillows. She wore earbuds and resting on her bed was her laptop. Her sister was naked, which gave Rachel a shock, but it was what was happening between her sister’s spread legs that really ramped up Rachel’s terrible curiosity. Lucy held some kind of long, white thing between her legs and she was pressing it against her hoo hoo as she looked at her computer and made little moaning sounds. Whatever she was doing it didn’t seem like she was in pain. Quite the opposite. It looked like she was really enjoying it! Lucy’s legs trembled and quaked. The hand not holding the white thing groped and toyed with her boobs and little tremors ran up and down her body in a way that made Rachel feel warm between her legs watching it.
Rachel stood, entranced, watching Lucy touch herself, and feeling that strange warmth. Recently, that hot feeling from between her legs had begun to happen more frequently. It wasn’t often. Sometimes, when a boy she thought was cute smiled at her, or when her eyes lingered a little too long on another girl’s boobs, while she wondered if hers would get that big. Other times, she’d touch her own little handful-sized orbs and the hot feeling would get really intense, but it happened most often when she showered and washed herself between the legs. Watching her sister doing those same things, she started to wonder if that was going to happen to her, too. Unconsciously, her hand slipped between her own legs, much like Lucy’s, and she began to rub herself through her pajama shorts, making the warm feeling grow.
Lucy’s eyes shifted from the laptop and met her own. Rachel’s breath caught in her throat. For just a second, her sister stared at her, the open-mouthed look of pleasure turning to anger, and then she dropped the white thing on the bed.
“Goddammit, Rachel!” Lucy yelled.
Rachel shrieked and fled down the hall as her naked sister leapt from the bed and tore toward the door. She shut and locked her bedroom door just seconds before the sound of Lucy’s fist banged against it.
“You little pervert!” Lucy yelled and hit the door again.
Rachel pressed her back to the door, as though her small body would lend some kind of added protection against her sister’s fury. She felt the door tremble as Lucy tried the handle, found it locked, and then banged it again. Rachel began to cry, cursing her stupid curiousity. Lucy went quiet, but Rachel could still sense her on the other side of the door. She continued to cry, sobbing in fright. A few tense, silent moments passed.
“Rachel,” Lucy said, the anger gone from her voice, “Rachel, open the door. I’m sorry. I’m not mad.”
Rachel trembled and continued to cry, feeling ashamed and stupid. Why couldn’t she just leave well enough alone? She always had to know.
“Rachel, come on. Don’t cry. Open the door. Please?”
Rachel wiped at her eyes and slowly got to her feet, turned and looked at the door. She turned the handle. The lock snicked. She opened the door, hanging her head, trying to look as small and pathetic as possible. Lucy pushed the door open, her lips pressed in a flat line as she stood naked in the doorway. Rachel blushed at the sight of her nudity. Her sister let herself in and put her arms around her, pulling Rachel’s head between her naked breasts.
“You little brat,” Lucy said, “What did you do that for?”
Rachel began to sob again, feeling ashamed.
“I’m… I’m sorry,” she choked, “I just heard a noise and I wanted to see if you were okay.”
Lucy stroked her hair, the warmth of her nude body feeling comforting as her sister shushed her like a baby.
“You and that curious fucking head of yours,” Lucy admonished her playfully, “I’m fine. I was just playing with my cunt.”
Rachel gasped at the dirty word. She’d heard it a few times on TV, and when she’d asked her mother what it meant, it had earned her a quick slap across the cheek and a warning to never say it again. It had not answered the question. Later, she’d looked it up online and felt dirty and hot between the legs, again.
“I’m sorry,” she said again, not sure what else to say.
Lucy sighed and said, “Well, next time you want to watch just fucking knock first, alright?”
Next time? Rachel turned her tear-streaked eyes upward curiously. She just couldn’t help it.
“Next time?” she asked.
Lucy smiled and Rachel felt better.
“If you really want to watch, it’s okay. I mean, it’s kind of kinky, but that’s sort of hot. Is that what turns you on? Watching?”
“What?” Rachel asked, not understanding the question.
“Does watching turn you on?” Lucy asked again, cocking her head.
“I don’t… I don’t know.”
“When you masturbate. When you play with your cunt, do you think about watching other people?”
“I don’t… I don’t do that!” Rachel said, blushing.
Lucy furrowed her brows curiously, looking her sister over, a look of disbelief on her face.
“You… you don’t?” she asked.
Rachel shook her head. Lucy’s lips spread up into a grin that made Rachel feel slightly uncomfortable. Something in the way she looked at her made Rachel shift her feet. She’d never seen someone look at her like that. The look made her squirm, but also caused that hot feeling to come back and make her skin warm.
“Come with me, brat. You want to learn something?” Lucy asked.
Rachel could not resist the pull of those words. Of course, she did. Lucy held her hand and guided her back down the hall to her room, where she locked the door and led her to the bed. She pulled Rachel down with her, pushing the laptop and the white thing out of the way. She made no attempt to hide her naked body, instead settling Rachel in on her side next to her, so that they lay facing one another.
“You seriously haven’t ever played with yourself?” Lucy asked.
Rachel shook her head.
“Never?”
“No.”
“Okay. I’m going to teach you something that every girl needs to know, alright?”
Rachel nodded, her eyes shining with curiosity.
“You have to be naked, like me,” Lucy instructed.
Rachel blushed.
“Rach, it’s okay. Hey,” she stroked back Rachel’s hair, the delicate touch making Rachel feel more comfortable, “don’t be afraid of it. You’re beautiful. Being naked is beautiful. It’s how people were made. Trust me. You’re going to like this. A lot.”
Rachel still wasn’t sure, but she did trust Lucy. She nodded her head and sat up, slowly pulling off her shirt, a red flush creeping up her body. She tossed the shirt aside, unsnapped her little bra, and then wiggled out of her shorts, kicking them off the bed.
“Panties, too,” Lucy said, something in her voice changing, the tone now huskier, somehow hotter. The sound of it made Rachel tingle. She pulled the panties down her legs and tossed them on the floor.
“You really are pretty,” Lucy said again, and slid her hand up Rachel’s naked hip, tracing it along the curve of her waist and up along her bare side, where her hand came to rest at the back of her neck, toying with a lock of hair. The feeling sent a shiver down Rachel’s spine, making Lucy smile at the sight of it.
“Is this okay?” Rachel said, her heart beat wild, “Are we supposed to be naked together?”
Lucy shook her head and said, “It’s only naughty for brothers and sisters. Don’t tell mom, cause she’s kind of weird about things, but it’s okay. Trust me.”
Lucy’s hand moved back down her body, caressing the swell of Rachel’s small breast, her nail raking lightly over her nipple and making it stiffen. Rachel bit her lip at the good feeling. Her hand continued its exploration, Lucy’s nail gliding along her bare tummy, and finally it reached the lightly tufted mound between her legs. Rachel parted her legs on some instinct, butterflies in her stomach as her sister moved to feel her.
“I’m going to teach you about your cunt,” Lucy said, her voice throaty.
Rachel blushed at the word.
“Cunt or pussy,” Lucy said again, “not that stupid baby word. You’re grown the fuck up, now, Rach. It’s time you learned about yourself. Do you want me to teach you how to make yourself feel good? Not like a little girl. Like a woman.”
Her curiosity in full control and her head feeling warm and buzzy, Rachel agreed. She’d barely finished nodding her head when Lucy pressed her lips lightly against her own, the warmth and softness of them taking her by surprise and making her inhale sharply at the contact. Lucy’s hand gripped her hip possessively, causing her to shudder. Her sister’s lips pressed again and this time her tongue snaked outward and ran along the length of Rachel’s lips, leaving a slick coating that her own tongue flicked out to taste. When she did, the tips of their tongues met, and Rachel moaned softly.
The warmth between her legs had come back with a vengeance and the strange feeling caused a foggy sensation in her head, like she wasn’t really present, as if she was more of an observer. Lucy’s tongue touched hers again, just a bit more aggressively, and then it parted her lips, and it was in her mouth. The feel of her sister’s lips closing against her own, the way they seemed to melt into her and the sound of the wet smack as they massaged her own, made the hairs on Rachel’s neck stand on end. Her whole body seemed to be buzzing pleasantly, and Lucy’s hands moving slowly up and down her back caused the heat between her legs to turn into a moist warmth like nothing she’d ever felt.
Lucy took Rachel’s hand and placed it on her own naked hip, and then she returned to stroking her. Rachel’s palm was sweaty as it rested on her nude flesh, her fingers trembling as she moved it first an inch, and then another, slowly mimicking the motion of Lucy’s touch on her own body. There was a feeling of electricity in her fingertips as they glided over Lucy’s more rounded curves. Her wider hips, the more graceful dip in her waist, then the swell of her breast under Rachel’s hand as her sister’s tongue explored her mouth, adding fuel to the fire that was now threatening to engulf her whole being.
Lucy’s fingers slid between her legs and touched her hoo– her pussy, and Rachel could feel the sensation of wetness there, coating her sister’s probing fingers. She moaned into Lucy’s mouth and squeezed her breast softly, bringing a reciprocatory moan from her sister. Rachel’s whole body tingled with little pin pricks of pleasure when Lucy began to smear the wetness around her delicate folds, her fingers gently pressing between them into the tight little slit, rubbing back and forth along its length, until Rachel felt her body quivering in much the same way she’d seen Lucy’s do earlier. This was what Lucy had been doing to herself? It felt so good! She’d never felt anything like it.
Lucy broke their kiss and looked into her eyes. Rachel’s parted lips trembled as Lucy’s fingers worked deftly between her legs. Her sister stared back into her eyes and her gaze looked slightly lost, like she was wandering in her own thoughts, but they held an intense and excited feeling that was impossible to communicate with words. She licked at her lips as she watched Rachel tremble and pant, an excited smile playing her lips up at the corners.
“Fuck, yes,” Lucy hissed, “That’s so hot, Rach. I want you to cum. Fucking want you to cum for me!”
Rachel wasn’t sure what that meant, exactly, and at this moment it was hard to really care. She felt something like an intense wave building up in her gut, emanating from her pussy and creeping its way up her body, setting every hair on end. She couldn’t control her breathing. She panted like a thirsty dog as Lucy worked her fingers faster, and then her sister touched some kind of magic spot at the cleft of her pussy and Rachel saw stars as the sexy wave rocketed up her body and enveloped her mind in an all-consuming feeling of bliss.
Lucy mashed her lips against Rachel’s as her head burst with pleasure. Rachel moaned loudly into her mouth, her whole body jerking as her sister’s fingers played her body like an instrument, sending it into writhing, spasming contortions that made her grunt like an animal as their lips smacked hotly. Lucy’s fingers withdrew but continued to softly strum the wetness between Rachel’s slit, causing the intense wave to recede to a level that allowed her mind to operate again.
“Fuck! That was so hot!” Lucy hissed, “You want some more?”
Rachel nodded her head eagerly, curious to see how many more times she could feel that way. Her entire being seemed to be singing with pleasure.
“Come up here,” Lucy instructed, and she sat up, then back against the little pillow cushion. She drew Rachel in, settling her between her own spread legs, so that her naked breasts pressed into Rachel’s back.
Her head in a delicious fog, Rachel allowed her sister to position her how she liked, trusting that Lucy would know how to make her feel good like that again. Her sister took up the white thing she’d been using earlier and clicked a button on it. The electric hum started up. Lucy kissed the back of her neck, just behind her ear and she shivered. Her sister’s hand squeezed her breast, her fingers pinching lightly at the hard, sensitive nipple. Lucy moved the humming thing between Rachel’s spread legs and pressed it against her wet, naked pussy.
Rachel’s body spasmed, jerking against her naked sister and she yelped at the insanely pleasurable sensation of the vibrations pulsing through her. The vibrator began to work the wave back up her body, making her tremble and shake as Lucy toyed with her breasts, kissed at her neck, and whispered softly in her ear.
“You’re such a sexy little slut, Rach,” Lucy said, and the dirty word made Rachel buck against the vibrator, pressing her pussy harder against it as the wave built, “I’m gonna do this to you every day from now on. Would you like that? Would you like to let your big sister make your cunt feel so good?”
“Yeah…” Rachel heard herself hiss.
Lucy held her tight, her hand groping and squeezing her breast, the vibrator pressed hard against her excited pussy as the wave began to overtake her senses again. Her head felt so hot, and the corners of her vision darkened. Rachel felt sweat building, slick and itchy between their bodies as she quaked in her sister’s arms, the peak of the wave about to crest. Then, Lucy pulled the vibrator away, making Rachel groan in protest as the feeling began to fade. Rachel wiggled her hips and whined. She could feel Lucy smile behind her and then she pressed the thing back to her pussy and made her gasp as the pleasure began to build again.
“You want more, don’t you?” Lucy hissed, “You want to cum so fucking hard for me.”
“Mmm!” Rachel moaned, panting as Lucy tugged at her nipple, pulling it outward painfully and letting it go, then repeating the motion again as the vibrations pushed her brain back to the euphoric state that she wanted so much to feel again.
Lucy pulled the toy again, just before she could go over the edge and Rachel shook, huffing in frustration.
“Please,” she heard herself whisper.
“Please?” Lucy asked.
“Please! Do it again!”
Lucy pressed the toy back and Rachel sighed with relief as the pleasure shot back up. Her sister repeated the process half a dozen more times, until Rachel felt like she was going to lose her mind. The continual denial, just as the wave was about to break, was maddening.
“I want you to tell me that you’re my slut,” Lucy hissed, “and then I’ll let you cum.”
“I’m your slut!” Rachel said, without hesitation, not caring what it meant.
Lucy pressed the toy back against her, held her, kissed at her neck, and finally allowed her to go over the edge. Rachel jerked in her arms, her body thrashing as the release finally came. She actually felt tears on her cheeks as the intensity of it sent such a wave of relief along with the wave of pleasure.
“Fucking cum you little slut,” Lucy whispered in her ear, “Cum your little fucking brains out of your head! Good girl.”
Lucy gave her another good, hard, body-wracking cum, before finally pulling the vibrator away, switching it off, and dropping it on the bed. Her sister kissed the back of her neck softly and held her, rubbing her sweaty, naked tummy as she came down, her extremities tingling and her whole body buzzing in a way that made her feel weak and tired. Lucy rolled her onto her side and held her, their nude bodies pressed together, the sweat between them cooling as Rachel drifted, half-conscious, until she couldn’t keep her eyes open.
