Sweat dropped down your brow. It wasn’t just the baking summer heat, but something more. Tiptoeing carefully toward the door, that icon of freedom, of escape, wincing at every errant creak of the floorboard. The outside air was so close you could almost taste it in your mouth, dry with fear. Yet no matter how badly you wanted to run, panic, sprint towards the waiting city, it was paramount that you took your time, controlled every last movement. Gently retrieving your key from the pocket of your shorts, slipping it into the lock, turning slowly, slowly, when suddenly, as if out of nowhere, she arrived behind you, and blew a burst of hot air into your ear.
She wrapped her arms around you, restraining gently as you felt her enormous breasts on your back. Placing her strong, yet soft hands on your chest, feeling your heart begin to beat faster and faster.
And she licked her luscious lips and whispered; "Hey, Onee-san wants to play~<3"
 
Exactly how had you arrived in this kind of situation?
 
Just a few months ago, your father’s marriage had fallen apart, after his unfaithfulness had been revealed. And yet, in no time at all, he was already remarried to the object of those new affections. Once the dust had settled, it was decided that you would be moving in with them, along with a new step-sister.  After all the teasing you had gained from your friends about moving in with a hot, older girl, you couldn’t deny you were a little excited. Yet, what you found was not some teenage fantasy, but a meek and mild-mannered girl by the name of Lily. She had an average figure, bright blonde hair, and a nice face hidden behind thick glasses. Lily turned out to be the timid kind of girl you could end up living with, yet barely notice it. She was always nice, and accepted you instantly as her little brother. And so, eventually, she just became another family member. There was nothing wrong with her, just, nothing special either.
Until last week.
As the summer began, she went on a trip; “to see the world”, “to find herself”, “to enjoy her youth”, and countless other explanations. The exact details of this vacation were a mystery to you, Hell, you weren’t even sure where she had visited. But one thing was for sure, she had changed. It was an instantly perceptible change in atmosphere the moment she stepped back inside the door. There was an energy about her that you’d never felt before. Her golden hair now flowed down to her butt, and her butt had grown enormous, like a fruit that had finally ripened. Her whole figure had become voluptuous and tempting, or rather her whole existence. Breasts like melons, hips like an hourglass, lips that were constantly plump and inviting. Even her gestures and speech had gone from meek and bland, to the epitome of seduction. And most shockingly of all, she had grown tiny horns, almost like a goat, petite bat like wings, and a devilish tail. It wasn’t like you hadn’t heard of a succubus before, but much like any rare and exotic beast, you hadn’t expected one to walk through the front door dressed as your sister. Lily even had to order semen from the local sperm bank to keep her alive; needless to say you didn’t eat together at the table anymore.
What would your parents think of this? A good question, but since they were on a second honeymoon in Tenerife, and were apparently too busy to call back even once, it was a question unanswered. You would have to wait until their return in a few days to find that out. It was a countdown until you could hope for some security. In the middle of a blazing summer, you were stuck in a house with a monster that very much wanted to get in your pants.
After all, despite the astronomical growth in business lately, buying sperm for food was awfully expensive.  And Lily always had been a penny pincher. And so, like every other day, your attempt to leave the house quietly, under some pitiful excuse, had been hopelessly interrupted.
 
“Don’t you wanna play something fun, little bro~?” Lily whispered, her very voice seeming to ooze and drip with lewd juices.  Long, slender fingers, with lengthy pink nails, roamed all over your chest, barely protected by a thin vest. “I know aaaalll types of great games, and they’re sooo much more fun together. Playing with yourself is just so… boring, isn’t it? Don’t you want Onee-san to teach you?”
 
 
Just when you thought you couldn’t endure another second, suddenly she removed herself from you, stepping in front of and allowing for your first good look at her today. Dressed in an incredibly short skirt, and a partially unbuttoned floral shirt, it seemed Lily had no plans of returning to the modesty of her human days. Her slender legs were bare, and her breasts and bottom were hardly better off.
 
“Aah, I forgot, it’s almost time to go to my job…”
You couldn’t even quite tell if she was wearing a bra at all…
 
“Hmm? Ooohh, did you get hypnotised by my boobs, little bro?” Squishing them together with her arms, she made a gleeful grin, hot flesh overflowing from her flimsy shirt.
 
“D-Don’t even joke about that! Who’d care about such gross cowtits?” One of the more terrifying things about the new Lily was her growing mastery of magic. You’d seen her hypnotise a man over something as trivial as a parking ticket; it was only due to her benevolence that you maintained free will. You were all too aware that a little hunger might cause her to turn you into her own personal food supply. That wasn’t a fate that really interested you.
 
“Oh, don’t be like that! If they’re too big…” Suddenly, her bloated blimps of breasts shrank down to the level of a washboard. Her shirt fluttered away without their support, revealing her bare nipples. Now that was a magic trick you’d never seen before, evidently her capabilities were only growing. Covering your eyes, you shouted out a response with a red face.
 
“Stop showing me something so dirty! What about your job?!”
 
“Hmm… But I do prefer playing with my bro… but I do need the money…” Sighing, Lily pumped her breasts up to their enormous size, jiggling freely, and filling out her clothes. “Then, I’ll see you tonight! Love you~!” The very moment her golden, hip length ponytail was out of sight, you let loose a breath you didn’t even know you’d been holding. Safe for today. Relaxing back in the empty house, you wondered if there was something she had in mind to buy with all the money she seemed to be trying to save. It would surely be bad news either way.Since you no longer had to pretend you were going out to see friends, it seemed like a good idea to do something useful and clean up the house, ready for your parent’s return. Lily’s room too. She was still your sister, after all. It felt good to do nice things for her.
 
--------------------------------------------------------------------------------------------------------------
 
“Little bro~! Did ya miss me~!”The peaceful afternoon was ruined by a loud shout, as Lily returned, unbuttoning her shirt and unwrapping a big, thick, Popsicle. Sitting on the table with her legs crossed, she hardly seemed to care that one wrong movement would give you a perfect up skirt view. Knowing she had your attention, she began to eat her cold snack in the most erotic way possible, fanning at her chest as liquid slathered her soft lips. “Ooh, it’s so hot today! I ought to take off some clothes~” Sliding the Popsicle in and out of her mouth, she let out little moans of pleasure as she attacked it from every angle with her long, dexterous tongue. Even as sugary goo dripped into her cleavage, she was just too lost in her display to care, eyes shut in appreciation. You simply stared at her with a constant, reddened face, and face that looked like it would explode if it was restrained a second longer. Lily crossed her legs coquettishly, one finger toying with her hair, drinking in your delicious reaction. "Mm? Brother, don’t tell me you’re jealous of this little lolly~ “She cracks an eye open at you mischievously, her hot breath melting away the lucky treat. Ignoring her words, you finally burst.
 
“Lily! What the hell, what the hell is this!?” You slammed down a leather whip onto the table. “What the hell is this perverse collection piling up in your room? Everything you’ve been saving up for? All this leather, all this…!” Her eyes widened at the sight, teasing games forgotten. No response was offered as she shuffled into a more proper posture. The house was silent, but for the intense beating of your heart, deafening all thoughts.
 
“Give….!” Your shout faded into a whisper. “Give me back my sister…”
 
The look of shock on Lily’s face persisted for only a moment before she opened her mouth.
 
“Give her back? What a joke. You barely knew her. Back then, you’d just treat me like part of the furniture. A background character. Now look. You can’t take your eyes off me. Every second of every day, you’re thinking about me.” Paralysed in shock, your body did not resist when she crawled into your lap, allowing hot breath to play over your face. “And hey, guess what? I’d already started buying that stuff waaaay before I found my true self." That was a serious shock. You'd never have thought bland, boring Lily, would have spent all her cash on such perverse equipment."Surprised? “Your sister” was always that type of person. I guess you just didn’t care to notice. Why did you even confront me about it? Wouldn’t you normally just ignore it? Like I did when I saw all those busty blondes on your PC… or maybe, just maybe, you /wanted/ Onee-san to know what you found… All this anger, all this disgust, really, it’s just a front isn’t it?” You swallowed heavily as her fingers interlocked behind your neck. “You just don’t want to admit that you’re so attracted to me you don’t know what to do with yourself~” There was no response you could offer as you bit down on your lip. Lily knew you better than you knew yourself. Why exactly had you confronted her with these lewd tools, instead of being a good brother and leaving them be? “Just what were you hoping would happen when you presented a Succubus with whips, leather, and all sorts of other fun things? Just what kind of naughty games were you imagining?” Swirling violet eyes were locked onto yours, spiralling, an unbreakable link. Lily licked her luscious lips, as though a hunger that had been growing for an eternity was finally to be sated. “Yes, I think my little brother has been very naughty indeed… I never knew you were so perverse…” Pressing herself onto you, there were now so many points of contact, you didn’t even know which of the countless soft sensations to focus on. “Yeess, little bro needs a good, long, punishing~” Before your mind could even process all the amazing aspects of the situation, Lily was back on her feet, and your hands were cuffed to the chair. Try as you might, both the wooden chair and the metal cuffs were stronger than your pitiful arms.
 
“Did…. Are you going to control my mind now?” Placing her slender fingers over her lips, Lily giggled, looking quite incredibly happy. Her grin was growing so wide, she almost seemed deranged.
 
“Are you worried about something silly like that? Onee-san doesn’t need magic to seduce a perverted little boy like you.” She ran her feminine hands down her incredible hourglass curves, emphasising just how incredibly endowed she was. “You’re just so fascinated by this new body, aren’t you? It really is a masterpiece!” Lily closes her eyes and pose as she speaks, arching her back, delicate hands pressing under each of her breasts and pushing them upward before dropping them and letting them jiggle back into place, sliding her hands down her waist and letting them come to rest on her hips. "I mean, I'm everything you could ever want! It must be /so/ hard~." Her tone of voice remains just as sultry as before, and a particularly malicious twinkle appears in those violet eyes. "You'd do /anything/ I say, wouldn't you~? For Onee-san?" Lily’s teasing soon becomes a full on striptease. Opening her shirt all the way, taking her time with each individual button, the fabric was left to flow at the sides. Each pop, each little progression, and you could see a little more of those gorgeous breasts, until finally, they were exposed in all their glory. Instinctively, your hands struggled with their bonds, wanting to submit to that most base male desire, to grab, squeeze, rub and grope! Lily couldn’t have been more pleased. “It’s useless, you aren’t that strong. Maybe, just maybe, if you promise to play with me every day, I might just let you have a little touch~” Giggling seductively, she twirled, spinning like a lewd hurricane, her temptingly short skirt giving just the tiniest glimpse of what lay beneath. You bite your lips so hard, it was almost enough to start a flow of blood. “Hey… don’t you want to know how it feels? A body made solely for pleasure…” Slowly, teasingly, agonisingly, painfully slowly, she lifted up her skirt. Her smooth thighs lead the way up to a tiny black thong, barely covering any of her perfect skin. It was a sight that drew in your eyes, and refused to release them. “All you have to do is agree to be my little pet, as well as my bro. And I’ll let you feel pleasure like you’ve only dreamed of~” It was just too much.
 
“I… I’ll do anything… I’ll be your pet… just, please, let me…”
 
“Admit that you’ve been mean to your poor sister, just because you were ashamed of how attracted you were to her.”
 
“I didn’t want… to admit how beautiful you looked… I’m sorry I was rude to you.” She was starting to purr like a cat in heat. Your obedience was pure ecstasy to her.
 
“Say that you secretly wanted me to play naughty games with you, using all my toys.”
 
“The moment I saw them, I got… excited. I wanted to use them!”
 
“Oh, now there’s a goooood boy!” Exuding an aura of happiness like you had never felt before, Lily stepped over and planted a loving kiss on your forehead, her bare breasts hanging in front of your eyes, forbidden fruit.
 
“Hmmm… I wonder what game Onee-san should teach you first~ <3 “
 
 
Your utter inability to satisfy your burning male instincts was maddening. A red, lustful haze was settling in your mind, clouding your thoughts. Whilst struggling with your bonds, your body unconsciously released a sad little whimper. Lily drank up that sound like a fine, mature wine. As she spoke, her gaze was not on your face, but firmly upon the growing bulge in your crotch.
 
“Awww, poor, poor, pet! You just want to touch my breasts soooo badly, don’t you? It’s unbearable, right? Don’t you just wanna run your hands down my luscious curves, hold me down, and shoot all that hot, yummy, stuff deep inside Onee-san?” Teasing you in a pitying voice, she lifted her meaty rump back onto the table, making no attempt to hide the treasure nestled between her smooth thighs. You could only nod pathetically in response. “Well guess what? If you want to do that so badly, you better start trying to earn it~” Reaching across for her little crop whip, Lily offered you your first task as her pet. “What’ll it be, little bro? Twenty kicks…” She smacked her open palm for emphasis, causing her chest to jiggle. “… or thirty licks for you?” Those slender thighs spread apart to form a ninety degree angle, that little black thong firmly at your eye level.
 
“Licks… please…” Your tongue rolled across bone dry lips in anticipation.
 
“Mmm… good boy~ Make sure to do your best for me.” Her thin spade-tipped tail slithered into her underwear, hooking onto them and dexterously flinging them aside. Smooth, pink, slippery and wet, her feminine organ was exposed to the air at last. Designed purely to entrance, pleasure, and exploit men, her inviting entrance was impossible to resist. “Come on, don’t be shy! One steaming hot, delicious, thigh pie, just for you <3” There goes your hesitation. Dragging your chair up to the table, you thrust your head between her supple thighs, beneath the canopy of her skirt, and began licking up every drop of her delicious nectar. Pooling in your mouth, the taste was addictive and sweet, like gourmet honey. The thin fabric of her skirt served to keep light away from your eyes, the darkness only heightening your senses of touch and taste. More and more sweet juices continued to trickle out, and like a hungry beast, you caught each and every droplet. That was when a sudden, sharp, shock was delivered to your back.
 
“Stop playing around down there! Hurry up, and make me feel good, or you won’t get your treat.” Done with her commands, Lily tightened her thighs grip around your head, swallowing you in a moist, sweet-smelling cave of lust. Renewing your efforts, your moist tongue delved into her burning hot insides. Thoughts of your eventual reward drove you to new levels of effort. It was almost surprising that you weren’t angry about how she had just hit you with her whip, unprovoked. It seemed like the most natural thing in the world, for the new relationship you had so quickly and vigorously accepted. As your lower body ached for release, another quick slap from the crop focused you on bringing your big sister the pleasure she deserved. Her thighs were beginning to writhe and rub against your ears ever so slightly, encouraging you yet further. Lily’s precious pussy was showered in short, repeated, movements, wearing down her resistance, with any lapse being punished with a stinging whip. Minutes flew by as you engrossed yourself in licking, licking, and licking. Your saliva mixed with her womanly juices, a hot, lustful blend of lewdness forming at the point where your two bodies met. Finally, after you were beginning to feel breathless and faint, her thighs convulsed, pressing you up against her sensitive spot with force, constricting you, giving you not even the slightest chance to escape. Not that escape was something you wanted, or had even considered. Your tireless efforts had finally borne fruit, the slightest moan reaching your sandwiched ears, as a spurt of her juices flooded your mouth. Soon, her legs relaxed, releasing you, and allowing you to bask in her glory, her face brimming with a beautiful afterglow.
 
“There… goood pet… you’ve earned a little reward…” Before you could respond or process this fantastic information, she was clambering off the table, unzipping your pants, and inspecting your engorged member. By the thrilled look on her face, it seemed she was very, very pleased with her new toy. Caressing it gently, as one would a priceless treasure, the stimulation was unbearable. The combined result of all her expert teasing, that eternity of licking, inhaling her aphrodisiac scent, had built into an unstoppable force. Before Lily could even unleash her skills upon you, white goodness burst onto her surprised face as ecstasy overcame all other senses, your vision flashing white. Wasting no time, her long, dexterous, tongue immediately licked up every last delicious morsel you had sprayed upon her.
 
“Mmm…. Ooh, it tastes so much better when it’s fresh~” For a moment, she was still, eyes shut in silent appreciation. An instant later, she was staring deep into your eyes, unflinchingly confident. “But, wasn’t that a little quick? Looks like you aren’t ready for the main event yet, my pet~” Just as her mocking left you feeling like you had failed, she planted a lingering kiss on your forehead and finally undid the handcuffs that had bound you for so long.
 
“But you performed admirably before… Yes, I think I’ll keep playing with you. Knock on my door once I’m finished showering, and I’ll prepare a really special game~”
 
And with that, your half naked, sweat streaked sister skipped happily up the stairs. The sound of rushing water filled the house as you remained motionless and dazed, paralysed by sheer disbelief. As much as this seemed like a dream, there was no way it could have been. The sensations were too strong. From the scent of her juices to the smoothness of her flesh, it was not something your mind could have conceived. The mere thought of the next lewd game sent a shiver down your spine.
 
-------------------------------------------------------------------------------------------------
 
Some time later, you rapped your knuckles against the door to your sister’s room. Trying to appear as calm as possible, to supress the shivers of excitement coursing through your body, you inhaled deeply. A few moments later, and Lily was before you, wrapped in nothing more than a towel, her blonde hair hanging freely behind her. The poor towel was having some trouble trying to contain her incredible figure, the sheer mass of seductive flesh overpowering the feeble fabric. Her breasts overflowed from the top like freshly baked muffins.
 
“Oh, little bro, did you want something?” Her demeanour seemed unusually quiet, calm, even tired.
 
“W-Well…. Um…. You were saying about…”
 
“Hmm, you’re certainly obedient, but… Thinking about it, maybe this whole thing isn’t such a good idea. I can’t spoil you forever.”
It was as though your heart stopped beating whilst your mind struggled with this bombshell. Your awkward, stumbling speech became frantic and desperate.
 
“B-But, Onee-san, you said-“
 
“I mean, what will our parents think when they get back? It’s weird for us to be doing these things. Just this morning you were treating me like dirt, too. I can just get what I want from other men anyway.”
Every word dragged your heart deeper into a black abyss, tearing at it in different directions. Why? What had changed? Your neurotic chaos was interrupted by the observation that Lily was standing silently, as if awaiting a response. Inhaling a lungful of air, you spoke;
 
“I… Maybe you can, but I can’t get what I need from anyone else! I don’t want to share my big sister, I don’t care what anybody else says, and I don’t want to carry on like this never happened! I’m sorry for how I acted before… I’ll do whatever it takes to make you forgive me. I’ll lick your feet, I’ll become your slave, and I will feed you so nobody else has to! Just, please, make me yours, and nobody else’s!
Once again, a lengthy silence filled the air between you, as Lily adorned an unreadable expression. Finally, she shattered the tense atmosphere with a girlish giggle. Her tongue ran over her lips indulgently as they cracked into a smile.
 
“Oh, I never knew you were so attached to your Onee-san. What a greedy little pet. Can you really give me my five a day?”
 
“If it’s you… I’m s-sure I can…”
 
“Hmm~” As she skipped around behind you, your fingers digging into your palms, you desperately hoped your body was up to the challenge. Unexpectedly, you heard the sound of fluttering fabric, and the unmistakeable, unbelievably soft sensation against your back, which you knew all too well. Yet, you would never truly get used to just how enormous her mammoth mammaries were, such great globes, perky and constant. When you noticed her hands dancing across your chest, you noticed they had been adorned with silky black elbow-length gloves. Such smooth fabric only made the ticklish sensations worse as Lily attacked your defenceless body. She didn’t hold back in her molesting, running her slender fingers all over, down your abs and venturing into your pants. Already well trained, you grew erect at the moment of her first touch. And then, she whispered a command, a simple one, into your awaiting ear.
 
“Show me how manly you can be.”
And just like that, her fingers began twirling over your masculine organ, expressing truly inhuman talent for bringing pleasure. Her voluptuous form remained firmly pressed against you as she wriggled happily, lingering teasingly out of sight. Wet, slippery sounds invaded your ear as she nibbled and suckled on it like a sweet. Nevertheless, all you let your mind focus on her command; you wouldn’t fail as simply as last time. Using all your willpower, you made it your single task, to resist this mind melting pleasure. If just a hand made you this helpless, then the rest of her body must…not be a fantasy you were about to indulge in. A sweet sinful voice of pure temptation soon invaded your brain.
 
“Much better… but how much longer can my pet hold out?” Her gloved hand began rubbing up and down your member with greater intensity, seemingly determined to extract your delicious juices. She seemed to be breathing awfully heavily. That’s when you considered just how tough it must be for a succubus to deny herself a big, juicy, meal, the main course, when it’s right in front of her. It might be even take even more willpower than you were exerting. There was no way you could ever understand that feeling.
 
“If it’s too hard… you don’t have to…” Her response was immediate and forceful.
 
“No! This is… what I’ve always wanted… my fantasy… and now that I’ve finally gotten the body of my dreams, I won’t let it control me!” Once again, you were struck by your ignorance at the process your sister was going through. All you knew was based on rumours and horror stories, truly insensitive. Her lithe and nimble fingers had become a whirlwind of passion, dancing across your most sensitive area. The entire world’s willpower couldn’t prevent the inevitable. Your hips bucked uncontrollably, before you burst, staining Lily’s pure black gloves white with your essence. Taking a moment to suck it into her eagerly awaiting mouth, Lily paused before offering her judgement.
 
“Hmm… you pass. Devoted and enduring.” Her slippery gloves once again rested upon your chest, pressing your two bodies together with increased force. “As a food source, as a pet, as a little brother, you’re good. I’m finally convinced. Now, close your eyes until I give the word, and I’ll show you something nice…”
Without question, your eyes slammed shut, locked tight. Once again, your body felt energised, full of life, even after you had so recently been drained. So far, your body’s endurance seemed to be up to par. Two down, three to go, and there was no sign of your libido weakening. Proving yourself was what mattered right now. To become closer to your sister, to learn more about what you had neglected, to make her smile.
 
“You may open your eyes, now~”
 
 
What stood before you was the essence of domination, everything that the word meant to you embodied in one girl. Lily’s lustful expanses of flesh had been squeezed into a tight leather bodice, the creaking of the material almost like groans of discomfort. How she had managed to even fit into it was something of a mystery. Her meaty legs were also contained within fishnet tights, and her gloves had been thoroughly licked clean. A tightly fastened zip stood between you and the heavenly hole your instincts drove you towards.
 
“Aah~ I didn’t buy this for such a sexy body! How troublesome…”
Remembering her earlier control over the proportions of her figure, you realised how easily she could fit into any clothes she wanted. You felt it would be most wise not to mention this to her.
 
“To start with… why don’t you get on your hands and knees, pet?”
As uncomfortable as it was, you knew there was no point resisting. You couldn’t overpower her to get what you wanted. Your cheeks heated up as you lowered yourself beneath Lily. The moment you were still, a foot clumsily pressed down on your head. Freshly washed, it had a flowery fragrance that invaded your nostrils.
 
“Hahaa… just a beast… can’t think of anything but sticking that juicy, throbbing, organ deep inside my sweet, burning hot insides…” As if addicted to her taste, you instinctively reached out with your tongue to lick at her spongy heel, causing a brief giggle to ring in your ears. Even through the stockings, you could feel just how pleasant her flawless skin was, without a blemish in sight.
 
“Now, strip. Animals don’t need clothes now, do they? You’ve no shame, after all.” Clumsily, yet quickly, you cast aside your attire. Lily soon followed with a gentle slap to your butt, followed by tender, inquisitive groping. You squirmed in discomfort, causing her grip to tighten.
 
“Your body is mine now… every last inch… Do you understand?”
 
“Yes, M-Mistress…” Ah, you’d finally gone and said it out loud. There was no going back now. As if the final taboo had been crushed, Lily gave you an affectionate stroke on the cheek. The sound of a zip unlocking, tooth by tooth, filled the silent room.
 
“Lie back… and give me… my meal… “
Pushed onto the carpet with surprising force, you were mounted like the animal you had become. Her exposed organ seemed to be almost breathing, pulsing, like a second mouth ready to devour its prey. And before you could prepare yourself, it was upon you, enveloping you in a heaven of lustful pleasure no man could imagine. A hundred thousand folds wrapped around you, coating your member in glistening aphrodisiacs, making you harder than any human should be able to become. With incredible self-control, she slowly slid up and down the shaft; her unnaturally strong arms pressing down on yours as she leaned back to let out a sigh of deep satisfaction. Golden blonde hair swirled around like a typhoon, shining brighter than ever before against the darkness of her skin-tight leather. Her tail coiled around your ankles like a binding rope, pulsing with the incredible heat that emanated from every inch of her plush skin. Even her demonic wings were writhing as she rode you, making her movements even more dynamic. There was no way any man could possibly escape from this situation. Her body was a masterpiece, designed a single pure purpose, to rape the male form. You didn’t even have the freedom to indulge in the bountiful flesh of her bouncing body, as much as you dearly wanted to grab on her enormous breasts, so cruelly trapped in their leather prison, far above. No, all you could do was lie back and be milked, a resource, an objective, a pet.
 
“Mmm… Come on… you can do better!” Her fingers dug into your forearm, her insides tightening yet further, so dearly hungry for your precious fluid. Your hips bucked and writhed with greater force, the force of this mating almost making you fear for the point at which she would let you go. Would she let you go?  Or would you remain here for the rest of your short existence, pleasured unbearably without repent, until every last drop of your livelihood was deep within her hungering stomach? Such thoughts twirled in your mind, as you finally, after so long, came with force. Pouring a load of hot, delicious, and thick semen directly inside her slender belly, you let out a girlish moan in time with Lily. Those tiny horns glowed a dirty purple as your male energy was consumed, fueling the unstoppable sex machine that pinned you to the floor. Gasping for breath, dripping with sweat, you stared deeply into those swirling, cold, violet eyes you knew so well.
 
“Ahh… We’re just getting started… Time for… the main course~”
 
-----------------------------------------------------------------------------------------------------------
 
Opening your tired eyes, long after your countless hours of sexual activities, you were instantly greeted by the towering figure of your big sister. She placed a finger over your lips, dressed in more conventional clothes once again.
 
“You played so very well, my cute little bro... I’ll be evaluating your performance, okay? Keep up the good work. I’ll need to make sure you’re sucked absolutely dry before those interfering parents get back…” The very thought of something coming between the two of you made you even more desperate to feed her all you could, as quickly as possible. Would they even approve? Would you have to arrange secret rendezvous to hide your lewd relationship from them? Lily pressed her finger against your lips with more force, silencing your questions.
 
“Now, let’s lay down some ground rules. When I get back from work, I expect three things. One! I want you ready to feed me. That means no playing by yourself, okay? No matter how much you find yourself fantasising about me. Don’t underestimate my nose. I know. I always know.” You sweated anxiously at that rather uncomfortable revelation, as she tickled your chin like a kitten’s.
 
“If I smell any delicious, yummy juice that hasn’t ended up in my tummy? I’ll punish you. And not in the fun way, so take that silly grin off your face. After all, how can you expect me to only play games with you if you can’t save up all your lust for me?” Nodding silently, it was a great relief to hear reassurances of monogamy.
 
“And secondly, I want all the chores done when I get back. The house should be nice and clean, ready to play in, understood? And finally… “Just as you were glad her conditions all seemed so reasonable, she reached out behind her back.
“…I want to be greeted after a hard day’s work by a hard working servant in a lovely apron. Don’t you think such a good house maid should wear a cute outfit?” What she held in her hands was a frilly, adorable, lacy, maid’s uniform. Her tail wrapped ever so gently around your neck, rubbing against the shaved skin as you swallowed nervously.
 
“R~ I~ G~ H~ T~ <3?”
