Chastity turned off the shower and the stream of hot water slowed to a trickle before finally stopping. She rang out her dark, shoulder length locks and stepped out into the steamy bathroom, grabbing a towel from the wrack as she stepped in front of the fogged mirror. The moisture was too thick to let her see her own reflection and she was grateful. She didn’t like how she looked without makeup and there was nothing especially to be proud of except her cheekbones and button nose, but that sounded like a consolation prize to her. Who was proud of having an attractive nose?

Her breasts were small, AA cup, which her friend Sally said stood for “Almost an A-cup,” and her figure was practically nonexistent. She’d hoped there might’ve been a last minute growth spurt after her seventeenth birthday but with her eighteenth just around the corner, that hope was fast dwindling. It seemed she was destined to be a diminutive twig for the rest of her life.

The new shave job didn’t help her look any older, she lamented as she dried herself off. Sally and she had gotten drunk last month when the other girl slept over, sneaking a few beers from the fridge, and had ended up watching pornography in a stupid effort to understand the male mind. Hairless sexes had been the norm, as had a number of other factors, such as large boobs, blonde hair and curves, none of which belonged to her. In an effort to be more like the moaning girls on the screen, she and Lisa had each trimmed and shaved themselves between their legs.

One week later and she was itching so badly as the hair started to grow back that Chastity had shaved herself all over again and kept it gone. She’d thought the effect would make her look more mature, but looking down at herself now brought a pout to her bow-like lips; it only made her look younger and more innocent. She wrapped the towel around herself and headed out the door.

Odd…she could have sworn she’d closed the bathroom door all the way to keep the heat from getting out. With a shrug, she pushed into the hallway and ducked into her bedroom, trying not to disturb her parents or sister, Evanore. Eva was back home from college from the summer and while she loved her older sister, Chastity was still getting used to having her around again after she’d been gone for so long. She’d left her downstairs earlier watching a movie with their parents before heading up for her shower.

This time she made sure she pulled her bedroom door shut before pulling on a lilac camisole and matching panties for bed. Girlish again, though she hoped the lace trimming made her seem more grown up. She wanted to ask Eva about college and what the older girls wore, but for some reason hadn’t been able to form a complete sentence around her since she’d come back. Maybe it had something to do with the strange gleam in her sister’s eye. More likely Eva had just grown up and left her in the dust. She wasn’t the same sister who’d been easy to talk to growing up. This was a stranger, a young woman with experience, and she had no idea how to open her mouth around her and not sound like a total ditz.
 
Evanora had excused herself from the movie, her parents smiling and assuming she was tired, a few minutes after Chastity had started the water for the shower. She creeped to the bathroom and cracked the door open, watching through the steam and glass slidng door of the shower stall as her sister bathed. The younger girl was skinny and less curvy than the average female, but she wasn't anorexic, her face was adorable, and she had a lovely curve to a somewhat plump backside.

Her breath caught when she spied the complete lack of hair on Chastity's twat. She shaved! Who would have ever guessed? Maybe she wasn't as "chaste" as her name suggested.

Evanora backed off and headed for the room they'd be sharing for the time being. She dug into her duffle and found a solution she'd created in chem class, dipping her finger in it before squirreling away again. She laid down on her air mattress, feigning sleep.

Evanora was a gorgeous girl, as it turned out. At 20 years, she had golden curls to her shoulders, peach-colored skin which had only on blemish--a strawberry, star-shaped birthmark on the underside of one of her D-cup breasts. Her hips were only slightly wider than Chastity's, ass a little more filled out. She had a piercing on her navel and a rose vine tattoo twining around her ankle and two inches up from there.

She had a feeling that Chastity envied her for her looks and experience, and Evanora would have no problem teaching her anything she asked about if the girl only asked.

She stilled further as Chastity entered the bedroom, the faint sound of the tv downstairs in the backgrund. Her blue eyes cracked a little so she could watch Chastity dress through the five-second view via the mirror on the wall.
 
Chastity gave a start when she noticed her sister asleep on the air mattress. She’d thought for sure the girl would have wanted to stay up with their folks and see the movie all the way through and completely forgotten they were sharing a room. Just one of those things she got used to without the older girl around. Luckly the slow rise and fall of her chest said she hadn’t noticed anything while she’d been changing.

Which made no sense to her. Why should she care if her sister caught a flash of her naked? She pressed the concern from her mind and let out a deep breath, forcing her gaze away from Eva’s chest. How did her sister end up with breasts like those porn star’s while she was stuck with mosquito bites? She pulled her gaze down to her own miniscule assets before giving her hair one last quick dry before hopping into bed and tossing the covers over her body.

Maybe she should get her navel pierced? Her sister was so beautiful, how could she ever hope to grab a boy’s attention with her around? She rolled over onto her side and stared at the wall, trying not to brood. It wasn’t like Eva had developed her body more on purpose to be more feminine than her own. She felt a little like the wicked queen from Snow White. Mirror mirror on the wall…she shouldn’t be jealous. She didn’t want to have anything in common with a fairy tale villain.
 
Evanora gave a convincing sleepy moan before tossing fussily onto her other side. She watched through the miniscule crack of her eyelids, waiting for her baby sister to drop off to sleep. Below, she could hear the quiet murmur of their parents downstairs, the tv only a smidgen louder.

The college student sat up carefully to see if Chastity would wake up. Nothing. She smiled to herself and began stripping. Her body was that of a normal woman's, if a little more curvy than average, until her pants came off.

There, between her legs, where a vagina should be, nestled a thick, perfectly formed, 11inch cock. It was the result of an accident at college, an experiment gone wrong, but she found that she enjoyed it more than having a pussy. Evanora gave it a good stroke and stood.

When still no reaction came from her sister, she edged toward the bed. Her sister was so beautiful and peaceful when asleep. She appeared less stressed, less worried about her looks, about school. It almost made her want to back off and merely watch her.

Almost.
 
Sleep refused to come and Chastity found herself staring at the wall, wishing she could turn her mind off. Every time she closed her eyes she saw her sister sprawled out before her in feminine perfection. Everything she'd probably never be all rolled up into one curvy, boy-magnet package. Mom and dad would flip out if she got a tattoo or pierced her navel, and somehow she suspected neither would look right on her, bust somehow it all worked for Eva. Everything worked for Eva.

Her eyelids were just beginning to grow heavy when she sensed movement behind her. Chastity's entire body went still and she held her breath. It was nothing, she told herself, probably just Eva getting up to use the restroom. She forced herself to close her eyes and resume normal breathing. What had her so on edge? Ever since Eva'd come home something had been making her tense. Maybe it was the sudden lack of personal space, or having an older, more accomplished and all around better version of herself around.

If Eva was going to go to the restroom, shouldn't she have opened the door by now? Strange. Was that the rustle of cloth she heard whispering in the room? No, she must be imagining things. Or maybe Eva had decided to change pajamas. It was none of her business what her sister chose to wear to bed, and she'd innappropriately ogled her more than enough for one day. She kept herself facing the wall laying on her side, eyes closed and chasing sleep.
 
Evanora slipped in behind her sister on the bed. At first, she just laid there. Then she delicately played her fingers over Chastity's arm, down her side, and down to the hem of her nightie. She caressed her pretty skin. Carefully, she scooted them further into the bed so she wasn't on the edge.

Her sister made sexy little murmurs in her sleep, and she paused to make sure Chastity wasn't awake. Then she slipped her hand inside Chastity's panties, cupping her clean-shaven pussy. She let out a soft breath, fingers slowly rubbing in the folds and then tormenting the clit.

Glancing around, she searched for something to restrain her sister a little. A broad grin crossed her lips. Evanora grabbed a silk tie Chastity occasionally used as a tie to go around her waist when wearing sundresses. She looped one end around Chastity's skinny little wrist, and then she tiedthe remaining end to a rung at the top of the bed, Chastity's arms now above her head.

Finally, Evanora pushed one of Chastity's legs forward, covered her mouth with the free hand, and pulled the crotch of her panties aside. She counted to three in her head, and then she thrust five inches of her large cock into Chastity's hot and newly-wettened pussy, deflowering her in her sleep.
 
Chastity stirred as she felt the weight of the bed shift beneath her and a hand gently guide her further onto the mattress. She murmured something incoherent and tried to recall when she'd fallen asleep, but a gentle caress sent a shiver down her spine and drove thought away in a flood of goosebumps. "Mmm...," the touch was so soft, like she was being touched by an angel. She buried her head in the pillow and tried to will herself deeper into sleep so that the dream wouldn't end.

A gasp flew from her lips as something forced its way into her panties. Her heart pounded against her ribs as fingers began massaging her nether lips. Of their own accord her hips thrust forward to maximize the contact, bringing the digits in contact with her clit, sending jolts of shocking pleasure through her core. Something low in her belly clenched and Chastity's blearily opened a crack.

Something was moving her hands up and she caught a glimpse of her favorite silk belt. Her hazy mind tried to process what was happening to her wrists and hands, but the cloth didn't feel bad against them. Still, having her hands tied was a bad thing, right? The question didn't matter because the sensation of that hand between her legs burned it away. How could something so soft be so rough?

Then the fingers were gone. Chastity groaned and forced her eyes all the way open and her wall slowly came into focus. The hand that had been touching her moved her legs and did something to her panties that left her hot sex feeling cold and exposed. A different hand found her mouth and held it shut. She recognized the stylish manicure. Eva? Her sister was touching her? What was--

Pain ripped into her, burrowing a molten hole up through her exposed pussy. Sharp and sweet, it swept up from between her legs as her hymen tore and flesh that had never been parted was ripped asunder. She screamed into the hand forcing we jaw closed and thrashed her hips, but only succeeded in burying the enormous thing that had penetrated her another inch. Blood and sex juices ran down her thighs and the shaft partly in her to dribble onto the sheets and cloth of her panties.

Tears washes away the last vestiges of sleep from her eyes and her lids shot open wide in shock and pain. What just happened? Eva was in bed with her, had touched her, that hasn't been a dream. And now she was hurting her. Why? She screamed again into her sister's hand and struggled to pull away, banging the headboard and slipping a few inches off of whatever her sister had shoved up inside of her. God, why had she done that?
 
"Shhhhh. Shh shh shhh shhhh," Evanora hushed, holding her sister gently. "It's all right, Chastity, the worst is over now. Hush now. Calm down." The blonde gently kissed and nuzzled her sister's neck, hair, and cheek. "There's a good girl. I'll make you feel good, I promise."

Evanora inched her free hand down to find the sexy folds of Chastity's sex. She cupped the mound and rubbed gently, then slipped her fingers inside the panties again. Her thumb immediately began teasing the love button at the top of her slit.

Meanwhile, she was working her dick back into the tight, hot hole she'd just plundered. She was almost too tight! God, her sister was small enough in stature that even her pussyhole was smaller than normal, even for a virgin.

Once five inches were safely and firmly esconced in her pussy again, Evanora began a gentle rocking motion. The movements weren't enough to move her dick more than a half inch in and out, the rhythm of the movements were more important. Her fingers worked in time, caressing Chastity's folds and clitoris lovingly.
 
The gentle whispers and caresses were so at odds with the pain burning between her legs in pulsing waves that Chastity’s mind failed to comprehend the mixed signals, leaving her lying sideways in her bed frozen as a deer caught in the headlights of an oncoming truck. Trapped by sensory overload. Her mind distantly tried to pull foggy pieces together to recreate the whole of what was happening in a way that Chastity’s conscious mind could comprehend.

Something large and thick was moving in and out of her. It had taken her virginity. Her sister had put it there. Her sister had taken her virginity. That last thought repeated over in her mind three more times before it actually made sense to her and when it did, she gasped as skilled fingers found her clit and drove the realization down under a hazy mixture of sensation.

Her hips bucked several times before adjusting to the feelings jolting through her clit, forcing her canal to contract around the invading member, each squeeze sending fresh new waves of pain tinged with pleasure. Why did it have to hurt so good?

The pain didn’t lessen, but the pleasure mounted, her body squeezing down tighter and tighter against the object being forced inside of her. She struggled to pull away, to keep the rising tide of unwanted feelings at bay, but only managed to make herself feel achingly empty as her hips managed to slip several inches out of her. She sobbed into the hand holding her mouth shut, wishing she could scream her pain, pleasure and confusion to the world and demand to know what her sister was doing to her and why.
 
Evanora pressed a kiss to Chastity's ear. "There there, it's starting to feel good, isn't it? I just want to fuck you so badly, Chastity. You're so pretty, and you don't even realize it." She licked the shell of her ear. "Don't worry, sweetheart. I'll show you just how beautiful you are."

The finger she'd saturated with that serum pressed against Chastity's nostrils, just under them so that when she breathed in, her little sister inhaled it. This serum had dual properties. When inhaled, pain was made nonexistent. When tasted, it acted as an aphrodisiac.

Hand still working down inside her panties, forcing more and more sensation on her sister, Evanora dipped her finger into Chastity's open, gasping mouth. She gently rubbed her tongue, making sure that the serum, conveniently cherry-flavored, worked into her system. She removed the finger once the solution was completely gone.

Careful not to hurt her, she turned Chastity's head to the side so they could look at each other more easily. "I love you, Chastity," she murmured, kissing that adorable button nose. "Maybe a little more than I should. But I'm going to show you just how much. This spring break, I'll fuck you and make love to you until you can't think of anyone else but me."

With that said, she released Chastity's mouth just long enough to claim her sister's bow-shaped lips with her own Angelina Jolie lips. For all intents and purposes, this kiss was more or less chaste, no more than clasping of their lips. For now, she wanted to make sure all of the solution was absorbed before she plundered her mouth with her tongue like she had Chastity's cunny with her cock.

Evanora pushed her cock in up to six inches now. She used the hand in Chastity's panties to keep her from bucking off of the thick length even as she continued tormenting her little love button.
 
Chastity tried to pull her head away from her sister’s whispering and whimpered as the tongue found her ear. What was Eva saying? It was all so confusing. SHE wasn’t the beautiful one, Eva was! And that didn’t at all mean that she wanted to have sex with her sister. She didn’t feel beautiful, she felt defiled. The pain was proof that this was wrong, that she was being tainted and ruined. Like a chemical stain on her insides.

Her eyes flew open at the sudden sharp scent of cherry, releasing the last of her tears as her pupils dilated, narrowing down for a few seconds before widening into impressive dark circles. The finger founds its way into her mouth and she involuntarily bucked back against the invading member. Where had Eva been hiding a strap on this large? At first the digit forced itself on her tongue but she soon found her appendage eagerly swirling around, trying to pull all the sweet tasting liquid from the delicate finger.

Chastity’s mind filled with pink haze. She couldn’t think. Dimly she heard Eva’s words as her head was turned, but they failed to register. Those lips were so full and lovely. Sally’d once called them blow job lips, but Chastity liked to think of them as kissable. Very kissable…and soft…wait, when had she actually started kissing them?

A dam broke.

Her hips rocked back against her sister’s tool, clenching down every time it pulled out, as if her canal hated for it to leave. She tried to press more and more against it, struggling to find a rhythm to match the fingers dancing on her clit and the thrust of Eva’s hips. Heat pooled below, spilling upwards into her body and coloring her torso, neck and cheeks bright red. She screamed around Eva’s tongue as the first orgasm crashed into her like an apocalyptic asteroid.
 
Evanora was thankful that she'd had her sister's lips captured with her own when she came. She muffled the scream so their parents wouldn't hear. She shuddered as she discovered that Chastity was a gusher, evident by how she'd been soaked down to her knees by Chastity's juices.

She smiled and pulled out of her sister, rolling her onto her back. She pulled off her panties, which were also soaked clean through with Chastity's own juices. The blonde set them aside and shoved the brunette's camisole up.

"Look down at your sister, Chastity," Evanora commanded softly. "Look what science can do." She cupped her dick and held it for her sister's dazed eyes to take in. "It's all natural. And if you're good, big sis can see what science will do for you." She knew her sister was embarrassed by her body, and she liked it the way Chastity was, but if Chastity was unhappy, then she wouldn't mind as much to improve her self-esteem.

For now though, she wanted to see her sister's reaction to a large, burgeoning horsedick throbbing between Evanora's legs, large balls swinging below. She stroked it, holding off her own orgasm for later. One hand trailed up, however, to toy with Chastity's perky nipples.
 
It was ecstasy. The muscles between her thighs clamped down as if trying to touch, squeezing down on the invader, which only made her feel more full. The twinges of pain accompanying each contraction dwindled away to nothing, swallowed by the pleasure, washed away by the flood of fluids and cherry flavoring. And then there was shame.

Had she just peed all over her sister? Oh god. She couldn’t even bring her hands to her face. She didn’t smell pee though, just the heavy musk of sex. Wait. Why did she care if she did something disgusting like that? Eva was…was it still rape if it felt this good? Could a girl rape another girl? Questions she’d never before considered drifted through the haze of her mind. She bucked her hips back against the member, eager to crest that mountain of euphoria. She was so close…

Her sister pulled out with a loud squelch, leaving her abruptly, almost painfully empty. Chastity’s channel clenched down on the sudden absence but couldn’t close all the way after having been so abruptly stretched by something so wide. Her nether lips were puffy and red, dripping with her juices and need.

She barely noticed her panties being pulled off until the air conditioning hit her wet skin and then she was distinctly aware of her camie being lifted, exposing her almost completely to her sister. Chastity blushed crimson and closed her eyes. Why would Eva want to see her naked? She didn’t have any of her sister’s amazing assets. Wait, why did she care what her sister thought? Dammit, this was too confusing. She wanted to be mad, to hate and hurt her!

Yet at Eva’s bidding she slowly opened her eyes and looked down the length of her body to see the massive member rising between her sister’s legs. What the hell? When had her sister become her brother? She even had a pair of enormous testicles dangling below the furious cock. The firs half of it glistened with wetness, tinged red with her virginal blood. Her sister hadn’t stolen her virginity with a toy, she’d used that thing, and had only half of it inside of her. It was revolting, horrifying, and absolutely the most erotic thing she’d ever seen.

Chastity gasped as finger’s found her nipples and belatedly the words her sister had been speaking to her made some degree of sense. But only some. Lots of science talk. Was she planning on replacing Chastity’s pussy with a cock like that, too? She shuddered at the thought, even as sparks flew from her nipple to her engorged clit. Her hips rose involuntarily and lifted up, trying to draw her sex closer to Evanora’s, her nether lips fluttering, unable to completely close. “…Eva…”
 
Evanora smiled and leaned forward on her knees, bracing her forearms on either side of her sister's pretty head. "Do you want something, Chastity?" she inquired. Her throbbing cock tapped against the smaller teen's tummy. She rocked her hips a little, the tip of her member smearing pre and residual juices from Chastity's pussy on the soft abdomen.

"If you want something from me, Chastity, you have to ask me," the futa-girl continued. Her plump lips gently skimmed over her sister's flushed cheek. "How else will I know?"

Her naked breasts hung loose, and as she caressed and nuzzled Chastity's face, Evanora's large melons brushed against Chastity's itty bitty titties. The unconscious movements of her hips made their nipples rub together, hard and sensitive.

Evanora shuddered and locked eyes with Chastity. She could see the mix of confusion and desire there. Need and hazy lust. The poor girl didn't even know what was happening! Evanora was surprised, though very grateful that guys hadn't taken advantage of her naivety and innocence. Gently, she rocked some more, resisting the urge to buck down into her.
 
Chastity moaned. Need ached through her so badly it hurt, cherry flavored desire slicing off the head of all protest and confusion. So many questions raced through the back of her mind, but as Chastity teetered on the precipice of ecstasy, the only one that mattered was: how do I get that cock back inside me?

She moaned again and lifted her body up into her sister, savoring the tingling rush that swept through her body as their breasts met, so mismatched and soft. How were they related with such discrepancy? Liquid pooled on her belly, a mixture of her own fluids and Eva’s precum dribbling from the monstrous male appendage leaking on her.

Her hips rose and her sex found the cock-root, the place where the appendage met the body, right above the testicles. She ground her clitoris into Eva’s flesh, shuddering as the stimulation suddenly sent a miniature orgasm crashing through her. Fluids rushed forth to drench the base of Eva’s cock and thighs, washing over her scrotum as it pressed against Chastity’s ass.

“P-please, Eva,” she begged, hips thrusting more and more wildly in desperation. That one orgasm was just the beginning. She could feel it. Feel the churning cauldron inside of her begging to be stirred so that its contents could rise up and spill forth. Over and over again. “Please! P-put it in me….”
 
Evanora groaned at the smallest of caresses, the most her sister can do in her state of confinement. Then she gasped as her sister's mini-gasm drenched her thighs and sac.

The more she let Chastity squirm, the more adorable and endearing she became. Evanora dipped her head, taking the entirety of one of her sister's tits into her mouth. She sucked it, tongue flicking over her little nipple. Her hands cupped the outside of Chastity's legs and lifted them up to wrap around her waist.

Finally, she thrust back into her drugged sister. A shudder ran through her as she felt wet, hot tightness envelop her. Her ears rang with her Chastity's cry of ecstasy. Groaning, Evanora began to thrust, not quite as hard and fast as she wanted, not yet anyway. Instead, she worked on getting a little more of her dick a little deeper into the hot channel squeezing around her.
 
Chastity screamed. Her womanhood clenched down in on the invading member, tightening and loosening as if trying to devour it, pulling Eva's flesh deeper and deeper. Her hips thrust up in an effort to speed up the process bringing her so tantalizingly close to another orgasm, yet the pace took off the edge just enough to keep from tipping her into the blissful chasm.

It wasn't enough. Her head rose up and she crushed her lips to Eva's, devouring her mouth before breaking away in an effort to kiss lower. The silken bond held her fast in place and she moaned her frustration at being unable to take her sister's breast between her lips.

She pressed her hips into Eva's with renewed fervor until she felt as full as she had before. More flesh slipped into her, reducing her breaths to ragged panting. The faintest edge of pain cut through the fog of flesh and drug induced bliss as Eva's cock pressed deeper still inside of her. Chastity moaned with each thrust as both sensations of pain and pleasure steadily, slowly mounted.
 
"I love you, Chastity," she murmured to her sibling. "My sweet baby sister. You have to be a little quieter. You don't want Mom or Dad to come up here and take my big cock out of your needy pussy, do you?" Evanora smiled as she aimed her cock to strike Chastity's g-spot twice. Then she straightened up, quickening the pace.

"You have the sweetest little moans. You want me to keep fucking you, don't you? I can tell you're a closet slut, Chastity. Soon you won't be able to go a day without a cock in you." She chuckled and decided to give her sister what she wanted, stuffing her gaping mouth with s much of her large tit as possible without suffocating her sibling.
 
The power of speech deserted chastity as the mixture of sensations overrode her higher brain functions, reducing her to only a few words and pathetic whimpering. Fortunately, her limited vocabulary retained her sister's name and the ever important "more!" which she alternated randomly between gasps. Evanora's own words seemed so distant, as if spoken from a great distance. Between the drug, the shock of her sister's strange anatomy, sort-of rape and abject pleasure experienced for the first time, Chastity's comprehension skills were at an all time low.

Dimly she recognized the need for silence, if only because some distant part of her recalled that fucking her sister, or rather, being fucked BY her sister in front of her parents was a bad idea. They'd make them stop and the feelings would go away. She'd be left feeling empty, just like before.

Unfortunately it became progressively harder to keep the noises fighting to escape her mouth at bay. She nearly screamed again the first time Eva's massive tool crashed I to her g-spot, and forced her jaws shut the second time, screaming in her throat instead, tears tracking down her cheeks as yet another orgasm lit her blood on fire.

She latched her mouth onto Eva's tit, swirling her tongue wildly about the nipple and lightly scraping it with her teeth. It took a concentrated effort not to bite down and her exhausted hips slowed their return thrusts.

She yanked her bound hands, fingers curling and uncurling in their desire to touch and feel her sister's softness. Her moans were swallowed by the delicious tit flesh in her mouth as she struggled to keep reciprocating. If she could only make Eva feel half as good as she felt now....
 
Evanora had to bite her tongue as her own orgasm hit her. Her back arched almost painfully as her dick exploded, filling Chastity with her semen. She hoped that her semen was sterile, as she had had it tested last week. Unpredicted developments could be horrible in this situation. The fury of her orgasm made those thoughts cut off abruptly, and she slammed hard into her sister, her dick as deep as it could possibly reach.

Then she slumped, rolling to the side. Chastity's body, still impaled, turned with her. Evanora placed her hand on the girl's brunette head, holding her to her breast. Even though she was exhausted, Chastity kept suckling, like a babe on mother's teat. Reaching up with her free hand, the bindings fell from Chastity's arms, allowing them to go free.

"I'll keep you untied..." she panted softly, "if you promise not to run away and tell our parents. If you're a good girl, I can promise you that you'll never feel empty and unwanted again." She knew that these words would have some impact on her baby sister. The girl was unsure and awkward, and she obviously had a bad opinion about herself. Why else would a few compliments melting from her older sibling's mouth cause her to melt into liquid butter?
 
Chastity whimpered when Eva’s cock bottomed out inside of her, thrusting up against something that felt decidedly uncomfortable and likely would have hurt much worse without the drugs coursing through her. But even that was beginning to wear off as her pussy clenched down tighter still on Eva’s cumming member, as if trying to squeeze every last drop fee and then hold the flesh inside of her.

Through it all she never stopped suckling. Suddenly her hands were free and they went straight to her sister’s breasts, massaging and squeezing, teasing the nipples. Everything she’d ever even remotely considered doing to Eva’s wonderful bust. The flaccid cock inside of her slowly slipped free to rest against her inner thigh.

How long she lay there she didn’t know, basking in the afterglow of her sister’s promises and pleasure. But slowly, it and the effects of the drugs began to fade. Her pussy throbbed in a completely new sense, aching in so many different ways she didn’t know what to do. Tears spilled from her eyes to trickle onto her sister’s breasts before she pulled away.

Slowly, she pulled herself out of bed and staggered to her feet, looking at Eva with a confused mixture of rapture and hurt. She’d taken her against her will. Nevermind how she’s somehow exchanged her girl parts for that monster between her legs, Eva had used it to steel her virginity. And it hurt, between her legs and behind her breasts. It had felt so good, wonderful even, but…but…she didn’t know what to think.

Their combined fluids trickled down her legs and she reached down to keep them from spilling on the carpet, awkwardly cupping her sex. A moment ago it would have felt exquisite, now it just made her feel sore. Her hand came away, palm full of pink tinged semen. Her blood, she realized dully. “I-I think I need a shower…”
 
Regaining energy and strength from the fading of her afterglow, Evanora stood. She took a moment, her legs wobbling, but then she walked forward and tenderly hugged her sister. She dipped a little, cupped her arms under Chastity's plump butt, and stood straight, in turn picking Chastity up off the floor. She carried her to the bathroom. The lack of noise downstairs suggested that their parents had gone to bed.

Evanora set Chastity down on the toilet and started a shower. She helped her inside, then shut the glass door to the shower behind the both of them. "Here, Chastity. Lean on me. I'll help you out. I know it hurts. Let big sister take care of you." She kissed the high school student's temple, then helped the water run over her as well as her own body.

Love and concern filled her as she shampooed her sister's hair, and then conditioned it. She was especially soft and careful with cleaning out her sister. Conscious of the confusion taking her virginity and then treating her like glass would cause, Evanora focused on just comforting and cleaning her sibling. Despite how well they were raised, she knew her sister was suffering from a shortage of love and tenderness. The inconsideration and stupidity of men who wanted nothing but big-breasted bimbos--girls that looked like herself--didn't help with that, and Chastity hid it well from their parents.

Well, if Evanora had anything to do with it, Chastity would at least know that she could always come to Evanora for anything, which now included some mindblowing sex and minor physical alterations. She finished with bathing Chastity and quickly cleaned herself up.
 
Chastity wasn’t sure whether to lean into her sister or not when Eva embraced her, but the decision didn’t matter. A moment later Eva’s hands were clutching her backside and lifting her up so that their breasts pressed together and her chin rested on her big sister’s shoulder. Blood tinged semen trickled out from her sex to dribble down Eva’s taught abdomen. She really was the big sister, Chastity thought absently, every single part of her was bigger and better.

She sat unmoving on the toilet as a few remaining fluids continued to drip from her. Just how much had her sister come? And then Eva was taking care of her. The hot water felt good on her aching muscles but stung between her legs and she winced at first contact. Slowly her mind began to function again and she fought to sort through her confused emotions.

What Eva had done to her had been wrong. On many different levels. But it had felt so good. Slowly, she brought her hands up to Eva’s body and began helping to wash her. She started innocently enough, but her hands soon drifted once more to those magnificent breasts. She was allowed to touch them now, right? The rules had all exploded in her face. Nervously, one hand drifted down Eva’s belly, hesitating a moment before lifting her flaccid monster and gently washing it.

“What happened?” she asked, rubbing soap up and down its length before gently reaching for the enormous testicles below.
 
Evanora smiled at her sister as she seemed to come to life again. She allowed Chastity to wash wherever she liked. Only sheer will kept her cock from getting hard again. "I had an accident in the lab," she replied once she was sure she wouldn't alarm her sister. "Someone put a wrong ingredient in my experiment, and when I drank it, I was racked with horrible pain. I went to my dorm and threw up a little, and then felt my genitals start to pull and ache. I took a pain medication that knocked me out, and when I woke up." She gestured at her cock. "There she be."

She finally rinsed off and turned the water off. She climbed out and grabbed a towel, roughly drying off. She handed another towel over to Chastity, holding her up so that her legs didn't give out. She picked her up again and carried her back to bed, thankful that their parents were safely ensconced in bed. She smiled and lay her down, cuddling her sister close. "I love you, Chastity. Don't forget that."
 
Chastity let herself sink into her sister’s strong grasp. Had she always been so strong? She wasn’t sure if she felt safe or not being carried around in the nude by her equally naked sister, but she was too tired to protest the strange comfort it induced. A horrible fear that their parents would suddenly wake up and spot them, struck her in a way her exhaustion and intoxication earlier had prevented, and she buried her face in Eva’s shoulder until she was settled down in the bed.

She didn’t fight her sister cuddling up, but she didn’t reciprocate. “Then why did you rape me?” Her body shivered at the question. The word seemed so dark and horrible to be associated with the pleasure that had wracked her body only moments before. Her sex ached now with the after effects of losing her virginity to that monster between her sister’s legs, but only a short time ago it had been afire with desire. Had she really been raped? Was it somehow her fault her sister felt she had to tie her up and force her?
