Love Thy Sister (Anonymous Mouse + Dagger Stiletto)

There was a long silene in which Evanora stroked and finger-combed Chastity's hair. How did one explain such things to a victim? She had to be truthful, yet in a kind way that will make Chastity accept it without fighting or crying, maybe even make her cuddle close.

"I took your virginity so no one else would," she said finally. "Anyone else would not have taken care of you the way I did. They would have taken what they wanted, convinced you it was the only way you'll ever be fucked, then dump you once they were done. It happened to me, Chastity, and it hurt twice as much, if not more. I was left broken, hanging over the edge of a tub. My roommate came in and found me. I was too torn to even pick myself up." She pressed a desperate kiss to Chastity's forehead as tears burned in her eyes.

"There's no way I'd want you to feel that, Chastity. I tried to make it as pleasurable as possible for you despite the pain. I tied you up so you wouldn't hurt yourself." Her arms tightened around the younger girl. "Please don't hate me." She shuddered, eyes closed. "I love you, maybe a little too much..."
 
Tears sprang unbidden for the countless time that night to Chastity's eyes. "So because you had a horrible first time you had to take mine?" No flowers or dresses or candles. No sweet seduction, just a sudden cock thrust up inside of her while she slept?

She rolled over so that she was facing away from Eva, staring sullenly at the wall. "You say you love me, but I don't believe you." The tears rolled down her cheeks. "You're so selfish. You've got everything and you wanted me so you took me too."

She blinked away the rest of the tears and wrapped her arms about herself as if to wars off the cold. "The worst thing is," she said, painfully aware of the dull ache between her thighs. "A part of me enjoyed it so much that it wants you back inside me right now." And never mind how uncomfortable, even painful that could be. Of their own accord her hips pressed backward to rub her ass against Eva's cock.
 
There was pain in her chest at what her sister said of her. She took a deep breath and let it go. Evanora knew that, all in good time, Chastity would see what she meant. She would understand and accept it as truth. Right now she was upset and didn't care about who she hurt.

Evanora curled around her sister, spooning her. She rubbed her flat tummy as she sobbed, as that action had always served to calm Chastity down and soothe her to sleep, even as a kid. The older sibling hummed the lullaby she faintly remembered the tune of, which their mother had sung during their infancy and toddler years.

"It'll all be better in the morning," she murmured against her sister's neck. "Big sister always takes care of you....and that's never going to change."
 
Chastity clenched her teeth, closed her eyes and waited for sleep, forcing herself to ignore the ache in her body and its newfound craving. She was furious with Eva and more furious with herself. It wasn't that she didn't believe everything she'd just said, but that in spite of it she wanted to do it all over again. Hell, she'd practically begged Eva to take her again, and her sister was being...sisterly. Dammit, what was she to her? A sister? A lover? Something to have sex once and then put up on the shelf like a china doll, or trophy?

She didn't recall falling asleep but when she opened her eyes the clock on the nightstand read 7:34. And Something hard pressed between her ass cheeks. Her sleepy mind suddenly remembered everything and it looked like Eva had morning wood. Her sex clenched with desire, sending a fresh wave of achey pain through her abdomen. Heat lit her face. Why did she want her sister's cock so badly?

Steeling herself, she pulled away from her sister, only to turn around and slide down Eva's body. Her hand went tentatively to the monster between her legs. She'd held it in the shower last night but it had been flaccid then, not erect like this. Her fingers barely wrapped around it. Hot and soft but iron hard. She bit her lip and slowly began to jack her hand up and down the length.
 
In her sleep, Evanora moaned but doesn't stir otherwise. Her skin prickled with goosebumps, and it flushed red with heat. Her mouh opened a little as her breath quickened a little. Unconsciously, her hand searched for her sister to cuddle closer. The long, thick pole in Chastity's hand twitched and darkened a little more with pooling blood.

Outside the bedroom, the parents were hurriedly bustling about, packing overnight bags. They had just gotten wind of a mutual friend needing an intervention, and they had to leave as soon as possible. They regretted having to leave during the time their oldest was there, but Evanora would have kicked them out once she found out.

Right before they left, their mother knocked on the door. "Chastity?" she called quietly.
 
Chastity gasped and released Eva's cock as it twitched and somehow grew larger still. She hadn't realized it could do that. Slowly her hand returned, finger tips just caressing the underside--then came mom's voice.

Chastity jerked away, sitting completely up. What had she been thinking! Worse, what if mom came in and saw Eva like this! Or did she already know? And not just Eva, but both of them together, naked. No way that erection would just be mistaken for something innocent!

She nearly fell off the bed in her haste to get away, throwing the comforter over her sleeping sister. Chastity tripped and flailed about, barely managing to snatch her nighty off the floor without careening into the dresser. "Yeah mom, just a minute," she half whispered in answer.

She slipped on the nighty and looked about desperately for her panties, but there was no sign of them. Where were they? Suddenly she realized that Eva's magnificent erection was tenting the covers. She barely managed to toss a pillow over the limo to disguise it before the door began to swing open.

Where were her panties? She sat down on the edge of the bed, legs tight together, nighty pulled down as low as it would go. And prayed her mother didn't look too closely at the sides of her hips. "Yeah mom, what's up?"
 
The mother smiled, glad to see that the girls had bonded and decided to sleep on the bed rather than separately. "There's been an emergency and you father have to leave for a few days, so you girls stay here and feed Beni." Beni was their father's pet iguana.

The woman stepped forward and kissed Chastity on the cheek. "Behave yourself. We'll be back in a few days." It pained her that she had to leave when her daughter had just arrived for two weeks from spring break. They hadn't gotten time to spend with each other yet, and now she and her husband were going out of town.

She pulled herself out of those thoughts as she heard her husband call from downstairs. She smiled sadly at Chastity, then at the peacefully sleeping Eva. "Love you girls. We'll call once we stop at a hotel." She turned and exited the bedroom, hurrying downstairs and outside to join her husband in the car.

Behind Chastity, once their mother had left, Evanora rolled onto her belly. She groaned, then very subtly thrust into the mattress beneath her, the satin sheets stimulating her sensitive member deliciously.
 
Chastity breathed a sigh of relief after their mother left, only to realize the full implication a moment later. In a few moments, she and Eva would have the house completely to themselves for several days. Her and Eva, completely alone…she shuddered, but even as she did, her stomach gave a delicious and familiar clench. She blushed and glared down at her bare sex, barely hidden by her nighty. What the hell was wrong with her?

She glanced over as Eva rolled and began humping the bed. Dammit, it wasn’t fair! She wanted to do that! Her hand slapped over her mouth as if she’d spoken the thought aloud. What the hell? She wanted to be the one to get Eva off? Was she really jealous of the freaking mattress? She shook the thought from her head.

Maybe she could get revenge. Her sister had to have some sort of sex toy or something hidden in her luggage, or maybe there was a large vegetable down in the fridge she could use to assault her in her sleep. But…taking her sister’s ass in her sleep didn’t feel right, not that she didn’t think either of them might enjoy it, but she couldn’t be sure. Violated as she felt, it had felt good at the end. The thought of having something up her own backside made her cringe. There was just no way to know without asking whether or not it was something that might eventually feel good to her sister instead of just hurting. Dammit, this was so unfair, why couldn’t she have Eva’s virginity too!?

She flopped back down on the bed and lay there, watching her sister unconsciously masterbate with the sheets. Gently, she reached over and rolled Eva onto her side, facing away from the door, just in case mom and dad hadn’t left yet, and wrapped her arm over her side. Once again, her small hand fell upon her sister’s impressive length.
 
Still asleep, Evanora remained completely unaware of what was going on. She knew nothing of the conversation that had just occurred, nor did she register being rolled over. Her siblings turmoil meant nothing in her unconscious state. However, her body reacted regardless. Wordlessly, she moaned in a sleepy exhalation. Her hips thrust, trying to get more coverage from her sister's hand. The blonde woman unconsciously pressed back into Chastity even while attempting to use her hand as a hole, like the pussy she'd plundered not too long ago.

The bed creaked a little under them as she moved. More breathless moans, barely audible, spilled from Evanora's naturally puffy lips. Then she rolled, reaching for her sister to hold into. She rutted into Chastity's belly, movements still languid in her sleep. Then she muttered Chastity's name, barely coherent. Her lashes fluttered but otherwise closed.

Eventually, precum began to ooze from her cock. The mostly colorless substance smeared over her length as well as Chastity's stomach as she continued to dry-hump--well, not so dry anymore--her baby sister in the dark of the bedroom.
 
Chastity let out a little “Eep,” as she lost control of the situation and found herself replacing the matress as Eva’s humping board. The precum soaked into the nightie, which Eva’s member had somehow managed to slip beneath, so that the little damp spots clung to both their flesh where it touched.

Chastity struggled against her sister’s hold but Eva’s grip was strong, and she was distracted by the way her empty channel clenched down, aching and lustful at the same time. She found herself angling her hips and squirming up, so that the cock rubbed its length along her clit with each thrust.

Chastity moaned with each little bolt of lightning that shot through her body. It was too much. She angled her hips further, awkwardly arching her body and timing her own thrusts to control the amount of direct contact on her most sensitive nub, instead allowing the member to rub against her tender nether lips, her own arousal lubricating it so that it mixed with Eva’s precum as her cock rubbed against her belly.
 
The blonde groaned and finally awoke, though groggy. Evanora nuzzled clumsily against her sister's neck. She moaned and arched, her cock sliding along the full crease of Chastity's pussy. She shifted again, and now her tip rubbed against the hole. One last roll of her hips, and the tip, but only the tip, popped inside Chastity's entrance.

Evanora gasped and moaned, feeling the fluttering walls clench desperately around her. Her scientific, brilliant mind was still partially asleep, so it was hard for her to focus, but a vague part of her wondered if her scientifically enhanced man-parts produced sperm that had addictive qualities like cocaine.
 
Chastity let out a groan, simultaneously wanton and full of discomfort as she was entered. Her hips bucked, but whether to draw Eva's member the rest of the way into her wet but sore channel or to escape, Chastity couldn't tell. The head already spread her open with delicious anguish and she groaned again, grasping at Eva with blind fingers, trying to find something, anything, to grab hold of.

The sound of a car started in the distance and the engine rumbled, a low steady sound. Their parents weren't gone yet. Their mother could still come back in. Shame and embarrassment turned her face read and she closed her eyes and looked away, as if trying to bury her head sideways into the pillow. Why did it have to feel good? She should be fighting harder. Should be trying to get Eva off of her, grab their parent's attention before it was too late. And yet all she could do was groan again.
 
"Shhhh," she whispered softly, one hand smoothing down her sister's side soothingly. Evanora kissed her sleep-mussed hair, rolling her hips gently. Inch after inch slowly slipped deeper with every thrust. "I love you, Chastity. Be a good girl and be quiet until Mom and Daddy leave. Then you can be as loud as you want." She reached down and gently rubbed her sister's labia and clitoris, her other hand curled around her and switching between squeezing and massaging each breast.

Evanora rolled until her sister was under again, grinding in down against her. Nuzzling the hair away, she kissed and licked Chastity's neck and shoulder possessively. Her beautiful sweet sister becoming her permanent cocksleeve, her cumpdump, her plaything, was more arousing than anything she'd ever thought. And if Chastity wanted Evanora to help in getting her bigger breasts and a rounder ass, well who was she to say no? Anything for her baby sister~
 
So full. So full yet so empty. She needed more. Why did she need more? Every deeper thrust stretched her sore passage, sending sharp pain lancing through her tender hole and up through her belly. But it also felt good. If the thrusts had t been so gentle it wouldn't have felt so good and Chastity found a large part of her wished her sister would speed up, if only so that the pain would overwhelm the pleasure and give her back some small portion of her sanity. She wasn't supposed to like this! Wasn't supposed to thrust her hips back up to take more of her sister's cock deeper and deeper inside.

She let out a sharp cry when Eva's fingers found her clit. Her entire body shuddered and her passage clamped down on the invading member. Tight. She was too tight. There was no way that huge thing was supposed to be able to fit inside of her, especially like this. And yet her traitorous hips kept thrusting up, even as she felt as if her insides had turned into a vice.
Her breasts weren't enough to even fill her sister's palm, especially not while she was on her back. But her sensitive nipples sent little shocks through her body with every caress and pinch and she squirmed all the harder for it.

She wanted to scream. In pleasure, in terror, in rapture, in pain. She wanted mom to come hold her and tell her everything was going to be alright. Distantly the rumble of the garage door opening to let the car out sounded. If she screamed now, they might still hear her, might be able to rescue her from the terrifying idea of a week at Evanora's mercy. So why was she trying to muffle herself? Why was she biting her pillow case to keep from crying out? The door sounded again, closing behind her parents and her only hope of salvation. She needed to cry out, to scream, to beg for help.

The orgasm hit out of nowhere. She screamed and screamed as her entire body convulsed and fluids rushed to fill her passage around Eva's cock. Her return thrusts became more vigorous, the pain more distant...and there was no sound of the car or garage or mom and dad. She was alone with Eva and completely at her mercy.
 
Evanora smiled and pulled out of her sister. She hadn't come yet, but that was okay. She had complete control over her cock. She could get hard and come whenever she wanted. It was like another arm--it didn't move unless she made conscious effort. Evanora scooped up her limp sister and took her to the bathroom. She lay her down in the tub and filled it with warm water, leaving her to soak and bathe. Quickly finding a salve she had developed in class, Evanora returned not even five minutes later.

Smiling, reassuring, she knelt beside the tub and carefully helped Chastity bathe. She plied her with sweet kisses and soft words of encouragement and praise, compliments about her pretty body. Naked as she was, she didn't have to worry about getting wet. When done, she helped Chastity out of the tub, drained it, and dried her off. She treated her sister like she was precious, wordlessly seducing her.

Chastity deserved to be coddled and protected, even while being fucked to oblivion. Evanora was more than willing and able to provide this attention.

She helped Chastity to sit on the counter, spreading her slim legs. Scooping some salve onto her fingers, she smeared it around her little abused hole. Dabbing a little more, she carefully slid her fingers inside, spreading the salve on her sore passage walls and over the torn hymen. "I developed this salve for fast healing," she explained to Chastity, keeping her still with a hand to her hip. "The soreness will be gone in less than an hour, and any tears inside will be healed up. You won't have your virginity back, of course, but you'll be good as new." She kissed one of her soft thighs, then removed her fingers and wiped them clean, closing the jar of salve.
 
Chastity groaned between labored panting, hips jerking up to try and pull more of Eva inside of her even as her orgasm subsided. But Eva went flaccid inside of her and slipped free, leaving her messy, sore, and empty. And still her body screamed at her for more. Had Eva come? There was no helping that then but…holy shit, could Eva get her pregnant? The thought sent a sudden chill through Chastity and she went completely limp, allowing herself to be carried to and deposited in the tub without struggle and barely any sense of awareness.

The hot water on her well-used, deflowered pussy stung and she sucked in through her teeth as it snapped her back to reality. She couldn’t even say Eva had raped her that time, could she? Why hadn’t she called out? Why hadn’t she told Mom? She’d been right there! And why wasn’t there a sloppy mess of her sister’s cum to clean up again? Hadn’t Eva come inside of her, or had she just lost her erection after Chastity had come? She swallowed with the realization. She hadn’t been able to make Eva cum.

There was something crushing about that. Because she wasn’t already inadequate enough, she had to suck in the bedroom too. She stayed quiet as Eva washed her, letting her have her way with Chastity’s body. Against her will, her nipples hardened, and why wouldn’t the heat between her legs go away? Slowly the touches built the heat up until it burned away the guilt and worries into the back of her mind. By the time she was spread on the counter, her passage was hot and creamy.

She let out a small gasp as the fingers penetrated her with the salve and tried to keep from clamping down on them. Chastity closed her eyes and looked away. This part wasn’t supposed to be sexual, Eva was just trying to put some healing cream on her, or whatever that stuff was. It was shockingly cool to the touch and thick, but even so, she had no doubt Eva could tell exactly how aroused she was. “W-what on earth are you s-s-studying in college?” she stuttered, trying to distract her sister as much as to think straight again.
 
Evanora hadn't missed the reaction to her fingers inside her sister. She scooped Chastity up and carried her back to the bedroom. "I'm a scientist. We study all kinds of things," she replied simply.

She smiled and lay Chastity back on the bed, splaying her limbs so the older sister can see the younger to full advantage. Her cock is hard and throbbing, eager to be buried inside Chadtity once more. "Mostly, I'm looking into hormonal and intravenous solutions to cosmetic surgeries. For example, by injecting a serum here," she presses an area outside Chastity's areolas, "breast growth is natural and painless and takes less than ten minutes to complete. The amount of the serum determines the size of growth." She bent and licked her kid sister's little nipple, her gingers teasing the other.

Lifting up, Evanora continued. She turned Chastity onto her stomach and grabbed handfuls of Chastity's normal white-girl butt. "Another serum injected here can give skinny girls with flat butts a lovely bubble. These serums negate t6hr need for implants and painful, debilitating surgeries. And guess who created them~"

Her fingers slipped between Chastity's asscheeks and rub against her untouched asshole. The other hand sneaked fingers into Chastity's pussy again. She delighted in Chastity's reactions, molesting her like the pervert she had become recently.
 
Oh God the monster was hard again. She might not have come before, but weren’t penises supposed to have a hard time getting up again so soon? And how on earth had she fit that thing inside of her, not only once, but twice! She made to cover herself, squeezing her legs together but before she could hide her breasts, Eva was upon them.

Chastity tried to retain what Eva had told her but it was hard with her breasts being played with so expertly. Her nipples sent little electric shocks through her body that made her hot girlhood squelch as it tightened. Already it felt less sore, but she wouldn’t have cared either way. It felt so EMPTY. It was with a strong act of will that she pulled her mind from the haze to really think about what Eva was saying. Ten minute breast growth. Why the hell wasn’t her sister a freaking millionaire? Or was it still in development? This had to have something to do with the new cock between her legs. She shuddered at the thought of being made to grow one of her own. What would it do to her? Already she felt like an enormous slut with a boyish figure, adding a penis to the mix would be horrible.

Before she could think on it further, she was flipped over and an entirely new fear engulfed her as her sister’s fingers touched upon her virgin rectum. The sound she made wasn’t exactly a scream, it was way too quiet, but she lurched forward, eyes tight shut, and buried her face in the covers, shaking her head as new tears came to her eyes. A string of girl-cum dangled between her pussy and the fingers that slipped out of it as she jerked forward. Not there, oh please oh please not there.
 
"Don't worry, sweetie, I know you're not ready to have anything more than fingers there." Evanora continued rubbing the dusky pink hole. Her touch remained gentle, and she bit her lip as she watched her sister. "You're so pretty, Chastity. I know you don't feel that way, but I think your gorgeous."

The older girl sat back and dragged her sister into her lap. At odds with the attention from last night, Evanora held her gently and tenderly played between her legs. The free hand turned Chastity's face, and she kissed her lips gently but deeply. She knew it had to be confusing for the teen, but the more she kept her off balance, the more Evanora would be able to shape her little sister.

Her fingers playrd in the wetness dripping from Chastity's core. The squelching noise as shr dipped her fingers inside made her want to moan, but she continued kissing Chastity inside.
 
“N-no fingers!” Chastity shuddered as she was pulled up into her sister’s lap, relief sweeping through her as the touch abandoned her rosebud. Only to be replaced with a moment of sheer panic. Was that monster penis aimed at her bottom? Mercifully it pressed against her ass cheeks and made no move to penetrate her. “P-please, Eva. I-I’ll do anything. Anyth-thing. Just please, please don’t hurt me there.”

Her words were cut off by her moaning as Eva’s deft fingers sought her most sensitive places. The moan was cut off by Eva’s kiss and swallowed whole. For a moment, all that existed was Eva’s touch, the kiss, and her fingers playing with Eva’s womanhood. Unconsciously, Chastity’s hips began to roll in time with Eva’s fingers so that her ass ground against Eva’s cock.

This felt good. Really good. Just a little bit more and her traitorous pussy was going to push her over the edge again. Without realizing it, she leaned back into Eva, pressing her sister’s much larger breasts into her back as she sank, becoming little more than a human puddle.
 
Evanora quickened her hands movements, observing her sister's reactions. Chastity had been a ticking timebomb; once awakened to sexuality, it was like she couldn't get enough if it. Eva thrust her cock so that it slid up and down the crease between her sister's asscheeks. Up and down, hotdogging as she masturbated her darling sibling.

Finally, Chastity came, and Evanora moved her fingers much more gently to ease her through the afterglow. She scooped up some of the feminine juices and smeared it over Chastity's tiny titties, smiling at the shine it lent them. Then she dipped the remaining cum into Chastity's mouth, forcing her to taste herself.

"Chastity, you're all mine now," she murmured, kissing her lips lightly, sharing the taste of her between their mouths. The older sister smiled, staring down her body to where Chastity's pussy drooled into the bed. "You'll never want anyone but me after this. You love your sister, don't you?"
 
Chastity screamed as pleasure exploded through her. The world faded out of focus and became blurry. Her pussy clenched down on the fingers toying with her, trying desperately to pull them up inside of her, to fill her in a way the nimble digits weren't intended. She felt so empty. So horribly, horribly empty.

Her throat was sore when she slumped back down against her sister, more liquid than ever before. She didn't have the energy or the heart to resist the fingers being shoved into her mouth and barely managed a wince at her own taste. Her mind wasn't able to keep up, wasn't able to fully process everything that was happening. Little tears came to her eyes, but didn't spill. She could feel her pussy juice trickling down her thighs.

She kissed back without thinking, the act purely reflexive and lethargic. Her tongue and lips slow dance partners only vaguely getting their rhythm. Good God she was such a slut! What kind of sicko came because their SISTER played with her pussy? She shivered, unsure whether to push forward or pull away. Eyes unfocused, thoughts scattered, and nipples diamond hard with her pussy still aching for attention, she nodded. "Y-yes."
 
She arranged her so that she was laying on her back with legs spread. She dipped her head and pressed her tongue to Chastity's sweet little pussy. She inhaled her scent, moaning in pleasure as she massaged her tongue against her younger sister's most intimate flesh. Evanora shuddered, aroused once more.

Her tongue slid inside, rubbing against Chastity's internal canal. Her nose bumped against the swollen, sensitive little clit, and she suckled wherever she could. Her sister's reactions, the little coos and the occasional convulsion of her pure body, were intoxicating, and Evanora wanted more and more. She wanted to take everything from her sister. Shatter her and build her back up into the perfect fucktoy ad pleasure slave.
 
She came again almost instantly. Fluids flushed onto Evanora's face as Chastity's hips bucked, desperate in their unthinking effort to remove the feeling of emptiness inside her clenching flesh. Empty. So empty. She jerked her face from side to side, hair flying in every direction as she fought back tears. Another orgasm was building, trying to crest, but she wasn't there. She ached with need she didn't want.

"Eva!" She screamed. "Eva please! P-please!" She couldn't vocalize more than guttural sounds beyond that as her fingers clawed the bed sheets.
 
Evanora happily continued sucking and licking the tender flesh, even going so far as to hum a little tune so it vibrated against Chastity. The older sibling stroked her hands from the younger's knees up her thighs, over her hips, and up her ribs all the way to her cute, tiny titties. She focused on the most sensitive spots on her newly awakened sex until she had that next orgasm.

Finally, the blonde lifted away from Chastity's pussy, licking her lips like a cat that got into the cream. "You beg me so sweetly, Chastity. What is it that you want?" She hovered over her on hands and knees, tits hanging down toward the more slender of the siblings. "Do you want my big fat cock inside you? Do you want me filling you, pleasuring you and fucking you until you come over and over, until you don't feel empty anymore?"
