Time to get the family involved...

After a rather exciting week at school, the weekend finally rolls around, and despite your enhanced libido, even you are looking forward to a bit of a break from the non-stop sex. You {if Futa==true}slink{else}groggily walk{endif} down the stairs to breakfast, still in your pyjamas{if Futa==true}, which are struggling to contain your feminine assets{endif}. Your brain is light years away, reliving the lesson with Miss Knight showing the girls how best to service your cock{if Futa==true} and your new body{endif}. It all seems so far away now... All you know is you can't get the memory of three girls sucking on your dick, whilst two others massage your {if Futa==true}breasts{else}back{endif} and Amy kisses you passionately, right in the middle of a school assembly.

"Heyyyy, {if Futa==true}Mikaela{else}Michael{endif}? Are you feeling okay?" The velvet voice of your older sister, Taylor, floats through the air.

"I'm fine," you {if Futa==true}call{else}grunt{endif}. It was distracting enough having your hot sister back from uni, even before all of this. Now lewd fantasies suddenly spring to mind, of you dominating her, caressing those big, perky tits on her...

"You sure?" Taylor persists, sounding rather amused. "You must have something pretty big on your mind."

"Oh yeah, why's that?" you ask, {if Futa==true}trying to contain your arousal as you drink in her gorgeous bod{else}not daring to look up as you try to contain your arousal{endif}. For all that your powers can do, you're not sure they'll work on your family, {if Futa==true}who - despite accepting your sudden transformation - have{else}who've{endif} probably developed some kind of resistance after 18 years of exposure. Even if they did succumb to your charms, you're not sure you're fully comfortable with the idea of ****, no matter how sexy Taylor may be. After all, you're having plenty of fun at school.

"Maybe the huuge bulge in your pants?" she giggles. "Or how about the tea you poured in your cereal?"

"Gaah!" you say, dropping your spoon and trying to hide your boner from her, as you quickly divert the blood flow from it. Taylor bursts out laughing.

"So, who is she?" asks Taylor, running her tongue over her lips as she watches you re-attempt the cereal.

"Who's who?" you reply innocently, but her dark amber eyes have the spirit of a tigress, and their powerful gaze burns a hole in your resolve.

"Okay, fine," you lie, putting down the cereal box. "You know Amy, right? Well, we're kind of {if Futa==true}futa{else}boyfriend{endif}-girlfriend now. So..."

"Oooh!" Taylor grins like a Cheshire cat. As a lesbian, she tends to be interested in this sort of thing. "So, now she's grown up, is she hot? Like, as hot as me?"

You freeze, stunned by the question. Taylor's always been your hot sister, but when you really look at her, you're overwhelmed by just what a knockout she is. She could probably top anyone in the school, even with the physical improvements you've given them. Taylor has her creamy, toned legs up on the table (crossed), exposing their full, impressive length as they gleam in the sunlight. Some short shorts serve only to emphasise the round shape of her perfect butt, whilst her white T-shirt is tied up to expose her trim abdomen. Two gorgeous, perky tits strain against their cage, large nipples clearly visible to you - she's clearly not wearing a bra. Finally, atop her shapely shoulders rests a gorgeous face, as Taylor bites her lip, framed by luscious sandy-blonde hair.

"Ummm," you stall, barely able to think as your sister arcs her back against her chair. "I... I never thought about it," you lie.

Taylor takes her fabulous legs off the table, and slowly struts round to you, hips swaying. "Well, tell me you're at least ready for it?"

"Wh-what do you mean?"

Taylor leans over, one of her large breasts pressing against your back. "Have you ever kissed a girl before?" she says in a low voice, her breath hot in your ear.

You don't answer. If only she knew.

"Let me help you," whispers Taylor, before she swings around to straddle your legs. Before you can even process it all, her soft lips are on yours as she gently, sensually kisses you. As her mouth moves over yours, you feel her place a hand behind your head as her movement begins to accelerate, and you instinctually close your eyes, focusing on your sister's passionate attention. Your mouth opens slightly, and her tongue seizes the opportunity to invade your mouth.

Just as you begin to respond to the delicious sensations coming from your mouth, Taylor's other hand grabs your waist as she pulls herself closer to you, her toned stomach pressing into you and her breasts squishing against {if Futa==true}yours{else}your hard chest{endif}. Your eyes shoot open in surprise, to find your sister ravenously gazing at you. Then she presses even harder into you, shoving her talented tongue deep into your mouth as she devours you, and you give into your desire. Your hands run all over her, fondling that perfect butt and sliding across her frictionless back, as each of you desperately tries to consume the other, to somehow get closer.

You allow your erection to grow to a comfortable eight-inches, so it pushes hard against Taylor's snatch, {if Futa==true}causing her to start in surprise. Cupping her chin, you gently lift her head back to face you, and gently plant a kiss on her lips. Her qualms seem to melt away, {endif}and she soon begins to rub her slit against your dick through the clothes, never letting your lips leave hers. She rubs you faster and faster, until she's full-on dry humping you.

Suddenly your sister pulls back from your passionate kiss, and you both gasp the fresh air.

"Not bad," pants Taylor, eyes wild. "Now be a good little{if Futa==true} dickgirl sister and let me eat you out.{else} brother and put your dick in my pussy.{endif}"

"What?" you say, slowly coming out of your haze. "Wait, Taylor, we shouldn't..."

"I won't tell if you won't," she grins wolfishly, hooking her thumbs under the waistband of your PJs. "Didn't you enjoy our kiss?"

"Well, yes, but -"

"- But you'll enjoy this more," finishes Taylor, slipping your pyjamas down, causing your cock to fly out and nearly smack her in the face.{if Futa==true} Glancing uncertainly at your large member, she lifts it out of the way to reveal your untouched labia. Taylor bites her lip, evidently trying to contain her excitement, and leans forwards to wrap an arm around your waist, her hand taking hold of your huge, rounded butt. Then she leans in, and pushes her mouth against your pussy.

It's like nothing you ever imagined. Sure, you'd touched your clit a few times in experimentation, but that couldn't have prepared you for the sensation of a skilled female tongue down there. Within seconds, you're letting out panting gasps, trying to process the feeling of her wet, warm tongue expertly massaging and caressing your magic button. You're certain she's torturing you, occasionally pausing to kiss your clit or lick your pussy lips, always going just too slow, leaving you **** for more.

It doesn't take long before you lose control, and shove your sister's head deep between your legs, forcing her mouth against your pussy. She makes a muffled sound of pleasure, before you feel her tongue enter your cavern for the first time. It's not as electrifying as the clit, but sends deep shivers of arousal up your body, and you feel the young muscles of your vagina beginning to tense as Taylor works on them. As if reading your thoughts, your lover brings in her second hand to your clit, and begins touching it like you never knew was possible. In doing so, she drops your dick, allowing your member to lie atop her blonde head whilst your balls rest on her forehead. Taylor is oblivious even to this, however, as she eats you out, rubbing your clitoris with an expertise you're sure must be unique to lesbians. Looking over her head - and your cock - you see her short shorts now sport a growing wet patch.

You soon lose the ability to think about your sister's enjoyment, however, as your own pleasure crescendoes until you can think of little else. Mindlessly, you seize your shaft and begin pumping its length, whilst your other hand gropes one of your tits, kneading it furiously through your pyjama top.

"Well, fuck me, Taylor," you moan. "You're gonna be the first to make me cum from my pussy. Oh god, you're going to make your futa sister fucking cum from eating her out. Oh ffuuuu..."

Taylor seems to take this as a signal to take it up a notch, as she begins licking and eating you with everything she's got, her fingers digging deep into your plump bum, your entire nether region trembling with pleasure - until it explodes. You feel your vaginal muscles contracting wildly for the first time, releasing a stream of nectar into Taylor's waiting mouth. Your cock twitches, a couple of small spurts falling on Taylor's back, but all the real action happens in your female organs. You toss your head back and groan with pleasure as your entire body shudders, until finally the waves of pleasure subside.

You look down to see Taylor frozen between your legs, and realise your pussy juices must have the same properties as your cum.

"Well, sis, I think we're gonna get to know one another rather well," you smile, breathing heavily. "Though you'll act the same normally, whenever I allude to sex you'll instantly be ready and willing for it. You'll be faithful to me and me alone, and be happy to share me with other women. You won't be surprised at any sexual powers I exhibit, including freezing people and reprogramming them, like I'm doing to you now. As my sister, you'll always be special to me, so I'll give you a gift: from now on, you have a tongue that can grow long enough that you can lick the inside of a woman's womb, and your own pussy will be constantly soaking wet, hypersensitive to oral sex, and able to take any kind of penetration." The rest of Taylor's body is already as perfect as you can imagine, so you leave it as it is, just giving her the same physiological improvements you give to your other girls, including an increased libido.

Your sister unfreezes, shuddering between your legs, before sliding onto the floor, dazed. "How was that?" asks your sister dozily, looking up at you with a dopey smile on her face.

"Incredible," you answer truthfully, taking her hand to lift her onto your lap. Spying some pussy juice smeared on her cheek, you wipe it off, and offer it to Taylor. Your sister eagerly sucks your nectar off your finger, eyes closed blissfully as she swallows it.

"My pussy is ssoooooo wet now," she murmurs, looking up at you with lidded eyes, a finger tracing its way up your flagpole. "And your big cock must be so hard right now..."

"I thought you didn't like the 'dick' part of dickgirl," you query, massaging her breasts through her clothes.

Taylor laughs. "Normally. But when it's yours..."

Suddenly she dismounts you. You watch, captivated as your sister pulls down her shorts to expose a hairless, soaking wet pussy. You stare at it, the pale fluid slowly oozing down Taylor's gleaming legs, then look back up as she takes off her shirt, revealing her perfect tits. Grinning at you, your sister sways over to the kitchen table, which she bends herself over.

"Fuck me, Mikaela."

You don't need to be told twice, seizing your hips and lining yourself up, before thrusting all the way in. Your sister is unbelievably tight, and she screams in an instant orgasm, collapsing against the wood beneath her. You're about to start pounding her, but too late, you hear someone descending the stairs. As a wave of panic hits you, you unintentionally cum deep in Taylor's snatch, causing her to let out choked moans as she writhes beneath you. You don't have enough time to hide your activities - never mind the pool of pussy juices on the floor.{else} You watch, captivated as your sister pulls down her own shorts to expose a hairless, soaking wet pussy. You stare at it, the pale fluid slowly oozing down Taylor's gleaming legs, then up at your sister as she takes off her shirt, revealing her perfect tits.

Fuck it, you decide - how can you resist her body? - and you strip the rest of your clothes off, revealing your new six-pack and muscled chest. The busty model before you smiles victoriously, but hunger quickly invades her expression as she takes in your naked body. Without another word, she takes hold of your penis - which you make a moderate girth - and she guides it into her dripping snatch.

You both gasp at the contact. She's surprisingly tight - even though you know your dick can't be the first in those warm folds - and her vagina feels like it's moulding itself around your cock. Taylor has to lower herself slowly onto you, breathing heavily as you feel yourself pushing her flesh apart.

She pauses halfway, taking several deep breaths as she looks at you admiringly. "God, Michael. If I'd known you had this beast under your pants the whole time..." She trails off, licking her lips as she resumes penetrating herself, until finally she sinks right down to your balls. You can feel her heartbeat as her pussy pulses around your cock, and you stare at each other with exhilaration.

"Mmm, what a good little brother you are," Taylor says gleefully, gyrating on your lap before slowly rising again, her juices providing perfect lubrication despite the snug fit.

"You feel fucking amazing," you murmur.

"Now kiss your sister as she rides your cock," she orders. You eagerly comply, your mouth meeting hers with an explosion of lust. As she descends on your dick once again, you move to suck on her elegant neck, letting her gasp as your sensitive head pushes her folds apart.

"Yes yes yes yes yes," Taylor whispers in your ear, slowly accelerating as she oscillates her hips up and down. You squeeze one of her soft, round butt cheeks with one hand, whilst the other pulls her abdomen close to you, arching her back. Your mouth leaves her now-rosy neck to attend to one of her bountiful tits, starting by teasing her nipple with your teeth. Taylor's breathing becomes more ragged from your ministrations, and she begins to let out small, involuntary moans, her voice catching repeatedly. Your sister's nails drag along your bare back as her arms mindlessly caress you, her soul now totally dedicated to her hot, wet vagina. Her bouncing continues to accelerate, her soft thighs now slapping against yours each time as she comes down, her breasts bouncing in front of your face, her feral eyes locked onto you as she penetrates herself as fast as she can. Each time she falls on your cock, you pump a bit more blood into it, making it just a little longer and wider, until you must be twelve inches long and three inches wide.

"I'm gonna explode inside you," you breathe, and Taylor slams her pussy down, wriggling to try and get you as far inside herself as possible.

"Ahhhh, don't cum yet," she moans, guiding your hand to squeeze her beautiful tits. "I want you to bend me over, Michael, and pound me like the naughty sister I am. Pound me until I ache inside."

You wordlessly lift her off your lap, and bend her over the breakfast table, brushing aside the crockery that's in the way.

"Don't be gentle," instructs your sister seductively. "Own my pussy, little brother. Fuck me until I can't stop screaming."

Grinning broadly, you line up your dick with her slit, now gaping wide, the perfect size for your huge shaft. Taylor's legs are splayed wide to expose it to you and emphasise the curve of her ass, juices leaking out onto her already-stained legs. She tosses her hair back as she looks back at you, and crooks a finger, inviting you in with an evil smile. It's all the invitation you need.

Your cock slams deep into her pussy, throbbing with exhilaration at the brutal action. Taylor gasps at the sudden penetration, then grins back at you. You ease back until only the tip of your glans is still inside her, then smash forwards with equal **** as the first time. "Faster," demands your sister, her hands clutching the edge of the table, and you willingly oblige her. Soon you're ramming into her as fast as you can, her bum smacking loudly against you with every thrust, your hands gripping tightly onto the curve of her hips as you jackhammer into your sister. Taylor's body is constantly shaking, her tits jiggling against the oak as she moans uncontrollably into the table.

"Do you like that, sis?" you ask, throwing a particularly deep thrust into the mix.

Taylor gives a hissing intake of breath. "Just... keep... fucking me Michael. Shove that cock... deep inside me. Oh, fu-u-u-u-u-u-uck!" She slobbers onto the oak surface, screaming incoherently as you reach your top speed, her writhing knocking crockery and cutlery off the table, until you see her eyes roll back in her head as her pussy clenches spasmically around you.

The squeezing of her pussy around your dick is enough to send you over the edge, in spite of your enhanced stamina, and you feel your cum preparing to make its way into your pulsing cock. You blast away with a groan into your slobbering sister, feeling the hot fluid filling up the little remaining space in her pussy, dribbling out past your dick. Taylor tosses back her head in a soundless scream of ecstasy, as her eyes transform into gold, and she enters the hypnotic state.

"Well, sis, I think we're gonna get to know one another rather well," you smile, breathing heavily. "Though you'll act the same normally, whenever I allude to sex you'll instantly be ready and willing for it. You'll be faithful to me and me alone, and be happy to share me with other women. You won't be surprised at any sexual powers I exhibit, including freezing people and reprogramming them, like I'm doing to you now. As my sister, you'll always be special to me, so I'll give you a gift: from now on, you have the power to make your pussy as wet as you like at will, and clench as hard as you wish or take an impossibly large dick, just by thinking about it." The rest of Taylor's body is already as perfect as you can imagine, so you leave it as it is, just giving her the same physiological improvements you give to your other girls, including an increased libido.

Just as you're finishing reprogramming her, you hear someone descending the stairs - but it's too late for you to clean up, only to release Taylor so she can have her explosive orgasm.{endif} Your dick still buried deep in your convulsing sister, you turn to see who's come down the stairs.
