Corrupting and impregnating her little sister. (ff, mind control, brain insertion, bestiality, impregnation, blowjob, incest)

abigail sighed as she came home from another difficult day at school. the 18 year old teenager kicked her little mary janes off as she put her backpack down, her milky brown thighs briefly visible beneath her pleated school skirt as she bent over to pick up her shoes and place them in the rack. an observer would have called the petite girl pretty, her innocent cherubic face framed beneath a head full of black curls.

as she walked up to her room, she heard the telltale sounds of her 19 year old sister tasha watching beast porn, the girlish moaning of porn stars mixing with the rough growls of dogs or the whinnies of horses getting their nut off inside the tiny girls. no matter how many times abi had complained to their parents about tasha watching her porn too loud, it always happened. and her sister had been stealing her panties. she was sure of it. her cute pink undies were always missing from her drawer and abi got in trouble with her mom for not putting away her laundry right.

abi didn’t want to have another fight with her sister so she went to her own bedroom; but the sound of beastfucking was coming from behind her slightly open door. pushing it open, she saw her sister still in her catholic school uniform, skirt flipped up as she stroked her brown teenage cock, moaning as she watched the porn on the laptop beside her. she was blatantly facing the door; she had wanted abi to see this.

‘gross,’ abi made a yuck face. ‘get out of my room, tasha,’

‘not yet,’ moaned her older sister, her hand palming her flat teenie tit through her white school shirt as she grinned at abi, beginning to buck her hips in an obviously exaggerated fashion. ‘i’m so close to cumming… are you sure you don’t wanna taste of this hot thick cheerleader cock? it’ll feel sooo good abi I promise,’ tasha winked, giggling as she bit her finger like she always saw the porn actresses do.

‘tasha i’ve had a really sucky day and I wanna go to sleep,’ abi groaned, stomping a pretty little stockinged foot. ‘will you please get out of my room??’

‘only if you let me cum in your widdle mouf,’ moaned tasha, licking her teeth as she stared lasciviously at abi’s small, pouty honey lips. ‘come on sis. how do you know you won’t like if you don’t try it?’

abi rolled her eyes, unable to hide her frustration. ‘you’re such a pervert!!’ she shouted, stamping her foot. ‘i’m telling mom!’

‘no you’re not,’ grinned tasha, reaching into her school skirt pocket for the surprise she had prepared…

as abi’s back was turned, hand on the door handle to run and tattle to mommy, she felt the parasite’s legs stick into her hair far, far too late. ‘aaaah!!!!’ she screamed as the many-legged thing latched onto her scalp, two of its tendrils immediately piercing into her ears, slithering past her eardrums and deep into her teenie brain. the thing’s body began to pulse as it pumped abi’s head full of aphrodisiac, suggestivity, and control; tasha grinned as she watched her baby sister’s eyes slacken, becoming more… aroused… her arms dropped to her sides as she began to moan uncontrollably, a small hand pressing up against her mons as she threw her head backwards in ecstasy…

‘hey abi,’ tasha grinned, stroking her cock victoriously ‘don’t you think it’s time you gave your first teenie blowjob?’

‘yes tasha,’ moaned abi, sinking to her little knees and shuffling over to her sister on the bed, her eyes dilating as the thing on her head pulsed and slithered. as tasha pushed abi’s tiny teen head down onto her throbbing cock, the innocent barely legal schoolgirl beginning to fellate her older sister. tasha moaned as she felt her sister’s mouth wrapping around her cock, a situation she had fantasized about ever since little abi had started developing…

‘yeah abi, that’s right,’ moaned tasha as she felt abi’s tiny bubblegum tongue lap at the head of her teenaged schoolgirl cock. ‘yes do that. just like that. oh abi yesss…’ she moaned, throwing her head back as she enjoyed the sensation of being sucked off by her little sister. ‘oh yes you’re such a good little cocksucker abi… just like I knew you would be… do you like the way your big sister’s cock feels in your little baby mouth?’

NO!!! abi wanted to scream, but her mouth said ‘yes tasha… oh yes I love it so much… it’s so hard and so soft and so warm at the same time… I wanna suck on it every day for the rest of my life… pwease tasha can I? can I give you a little blowie every day from now on? pwease?’ she licked the head as she begged, slobbering all over tasha’s girlcock as she jerked the shaft with her small teenie hands.

‘yeah keep talking like that babygirl,’ tasha moaned as she enjoyed the incestuous blowjob she was receiving. ‘if you keep doing that i’m gonna cum real soon baby, all over that little tongue of yours…’

the scent of tasha’s precum was turning abi on, just a little, but she would rather die than admit it. she didn’t like her older sister and her weird predilections, and so as she bobbed her pretty curls on her sister’s meat, focusing on making her sister hurry up as video footage of another tiny girl getting gangbanged by boars played next to her head… wait… no… this didn’t make any sense… she wasn’t abi any more… she was… she was…

‘oh abi yes,’ moaned tasha, her cute little butt arching off the bed as she pushed her sis down onto her cock, spearing it into her teen throat. tasha’s back arched as she came, her hands firmly on her little sister’s head, her school skirt bouncing as she fucked her tiny mouth with her teenaged cock. ‘oh yes baby girl! yes! take my teenage cum! take it! swallow it! take it all in your little mouth! yes!!!’

abi obeyed, her throat pulsating as she took every ounce of her sister’s huge load. she was dimly aware of the taste, like filtered bleach, but instead her little kitty was throbbing with pleasure as the thing inside her head transformed the sensation into honey, like manna from heaven, making her moan as she fingered her eighteen year old cunny…

‘more,’ moaned abi as tasha pulled out. ‘more. please sis. I need it. fuck me. use my little body. turn me into fuckbait. rapemeat. a little teenage cumdump. share me with all your friends. I need it tasha. I need to be shown what a bad little girl I am… just a teenaged fucknugget, a little babywhore… just a tiny teen body with warm little slutholes…’

abi didn’t know half the words she was saying, and while a dim part of her was horrified that she was using such filthy language, the rest of her was thrilled to be acting so grown up. for tasha’s part, hearing such slutty statements from her innocent little sister’s mouth soon had her hard as a rock once more. she wanted to act like such a little kid all the time? tasha was gonna show her how grown up she could be…

‘stand up baby girl,’ said tasha, abi slowly and unsteadily obeying. ‘this thing makes you mine for another six hours, and I plan to use every second of it,’ she moaned, stroking herself as she made her little sis bend over onto her anna and elsa bedsheets. ‘lift your skirt for me sis. yessss, show me that little kitty of yours…’

‘tasha that’s my naughty place,’ moaned abi as the tendrils wormed their way into her ears, drool falling from her mouth as she turned back to look at her sister. her pupils were so dilated…

‘yes I know baby,’ tasha said as she pushed abi’s panties aside and deflowered her little sister. ‘yessss… yes I know… oh fuck abi your little baby cunt is so tight, oh yes fuck your little kitty back onto me, yes, yes oh fuck…’

as the thoroughly hypnotized abigail began to moan and pant, the aphrodisiac overcoming her hesitance, tasha felt up the little girl’s chest to feel her puffy nipples hard as pebbles, pinching them eliciting a squeal of pleasure from abi’s mouth. ‘tasha please stop,’ she begged as she felt her orgasm coming, the first cum of her young life. ‘tasha please, I don’t like it…’

‘liar,’ moaned tasha as she prepared to nut in her sister’s little muffin. ‘oh baby abi you’re going to love what’s going to happen in nine months… i’ve been saving this load for weeks baby, and your fertile period is just about to hit… ohhhh yessss tell me to knock you up. beg me to put a baby inside your little baby womb please abi do it for me oh yes yes yes yessss!!’

her mouth moving despite herself, abi could feel her grasp on her body slipping as the parasite perched on her baby curls dug its feet into her scalp, its tendrils sliding around inside her dura matter as they squirted dose after dose of hypnotising goo into her teenaged brain. ‘oh yes tasha… tasha put a baby inside me, yes, make me pregnant, get my eighteen year old belly all nice and big, then when the baby is growing inside you can put your thick hard COCK inside my womb and teach her how to be a good little fetal cocksucker… oh yes! ye-ES TASHIE! TASHIE PLEASE! CRAM MY LITTLE KITTY FULL OF YOUR HOT STICKY BABY BATTER! YES! YESSS!!’

abi’s eyes rolled up completely into her skull, tasha cumming hard at the sight of her little sister’s eye whites as she filled her innocent, barely mature womb with her fertile nineteen year old seed. abi herself was orgasming, her tiny toes curling under her stockings as she squealed and gasped, unable to believe how much pleasure she was in… she tried to move, to resist, to fling her sister off her and run for mommy, but she couldn’t move… six hours? of this? oh she was going to die, whether of shame or of pleasure she didn’t yet know…

dimly she was aware that tasha had gone, but it was mere moments later that she returned, the family doberman padding after her.

‘rover, fuck!’ said tasha, grinning as the dog unflinchingly obeyed, abi screaming as she was penetrated by the dog’s enormous red rocket. tasha had trained rover well, having snuck out into his kennel nearly every night since after she had turned eighteen, fulfilling her teenie lust for zoocock, sobbing on her hands and knees as rover plugged her with his massive doggie knot. ‘just what are we going to do with this daughter of ours?’ tasha’s mom had despaired one day when they had caught her yet again with her mouth wrapped around rover’s slimy, veiny meat. but being the eldest girl, tasha was, of course, spoiled rotten; hence her use of rover to forcibly rape and violate abi’s little teen cunny.

‘tasha make it stop!’ screamed abi. ‘make rover stop! make this bug thing stop! I don’t want it! stop! you’re hurting me! it’s too big! how could you do this to me, tasha?! i’m your little sister! stop it! stop it!!’ wept abigail as she rocked back at forth at being cuntfucked by the family dog, his snarling drool soaking the back of her school uniform and her little white training bra – abi had never gotten big enough to need anything else.

‘you can stop any time you want,’ tasha said, grabbing the parasite and easily lifting it off abi’s head, the little girl moaning as the tendrils withdrew from her ears with a plop. ‘I lied about six hours. it was more like sixty seconds. but you’re clearly a much… much bigger slut than we both anticipated,’ tasha said, sitting her nineteen year old ass down in front of abi’s mouth as she lifted her skirt and plugged her sobbing hole with her cock. ‘aaah yes,’ she moaned as she pulled on abi’s curls, her own long black hair bouncing as she began to facefuck her little sister once more. ‘oh my god are you using your tongue??? you little babyslut! oh fuck yeah that’s so fucking hot… oh yes that’s sooo FUCKING hot… yes make him cum inside you, bounce your little hips like that… oh god the thought of all that sweet slimy doggy juice racing up your little fallopian tubes… are you gonna give birth to puppies, abi? you want that don’t you? answer me…’

‘…yes,’ moaned abigail. ‘yes tasha I do… I wanna have rover’s puppies… I wanna pop them one by one out of my little kitty and cum so hard as I do it… oh tasha i’ve known about you fucking rover for years… i’ve wanted to do it so bad… I touch myself every night imagining it’s me down there instead of you…’

‘but you didn’t want people to think you were a doggy whore, did you abi?’ tasha grinned as she forced her sister’s pale lips back down onto her shaft. ‘you wanted to be the gooood sister, the one people respected… well look at you now, you filthy zoofucking bitch! rover! fuck! fuck her harder! turn her into my bitch! that’s right doggie, fuck! fuck!!’

abi screamed as rover increased his pace, growling and snarling as his knot forced its way into abi’s tiny baby flower. ‘yes rover,’ groaned abi through gritted teeth. ‘fuck my little baby cunt like that… yes rover make me your bitch… i’m your bitch, too tasha, your good little whorebitch, cum all over my face… mark your territory… i’m your little babyslut now… all yours…’

rover howled as he came, jetting what felt like a gallon of doggie sperm into her little baby pussy; abi too howled with orgasm as she spasmed around his huge knot and the warm sensation of being filled with his fertile canine sperm. as tasha came on abi’s tiny, innocent face, her big sister grinned as she beheld the sight before her; little abi finally broken, a drooling, cumsoaked little babywhore, addicted to doggy cock and her big sister’s cum. the three of them were going to have so much fucking fun.
