Review. Next thing up soon. Sorry if this is a little on the short side or a little on the long side. This is a Bart making a harem three shot. Warning Bimbo's/pregnancy/incest typical stuff.

"Why the hell isn't Homer here?" Bart snapped at his mom as he sat in front of the very weird shaped machine that Professor Frink had insisted that the entire family sit in front of.

"Your father is very busy and incredibly tired today. So he was permitted to stay home while we all go to try out Professor Frink's brand new invention for him." Marge Simpson told her twenty year old son as she patted his head. Bart waved at her hands in irritation, he hated how often she treated him like a baby, it was humiliating. It also didn't help that he lived at home, had no job, no friends and seemingly no future.

In comparison his eighteen year old sister Lisa had graduated from college early, had a high paying job and was looking to move up in the world, and his even younger sister Maggie was starting to find other ways to make herself useful and begin to think about college because she was seemingly smarter then Lisa! Which should not seem posisble and yet totally was.

"Yeah Bart. Dad is exempt, he does have to support you." Lisa said snidely as she and Maggie continued to press and text on their phones. They had actually been the ones who made the appointment with Professor Frink and permitted their entire family to be a part of his strange and slightly other worldly experiment.

Lisa chuckled at Bart's red face and Lisa's snideness. The young girl smirked to herself and continued to play on her phone.

"Support him? I think you mean get hammered in his underpants and pass out in front of the television set again like the dumb fat ugly slob that he is." Patty said before taking a long drag on her cigarette and blowing a puff of steam out towards her straight sister Selma who repeated the action with her own lit cigarette.
"Ha! Fat slob, that sure is right." She parroted her sister before blowing her own smoke out towards Marge who cleared her throat in irritation, no matter what she did she could never seem to get those two to lay off of her husband.

"I think that you two are thinking of yourselves." Bart said snidely as he wrinkled his nose and waved away the smoke. Marge, Patty and Selma looked shocked before Marge frowned and gripped Bart by the arm.

"Bart! You apologize to your aunt's this instant!" Marge said shaking the noodle armed pot bellied burn out.
"But it's true! Why do you keep on letting them insult Dad like that?" Bart said as he moved out of his moms grip and walked backwards towards the machine that Frink wanted to test out on them.
"The harsh words of a child." Patty said shaking her head sadly. "All from that lazy no good bums side of the family."

Bart hated how hypocritical the two women were, after all they skipped out on their jobs to do this and he had seen them passed out in front of their TV's plenty of times. To think that they would just insult him and his dad and get away with it...it made Bart positively furious!

He gasped as he tripped over a wire and reached out to grab something to slow himself down, he found a handle and accidentally pulled it down. He heard an engine start up and turned to see the machine that Frink wanted to test out on them. The mad scientist had brought them into the room, had them sit down in front of a screen and in front of this weird ray gun looking thing, and then left saying he had to do a few things while locking the door. The scatter brained scientist had probably forgotten about them by now. Which sucked as that could mean they would be in here for days.

Bart actually envied Homer, he could just skip out on this and miss all of the annoying estrogen that filled up this room. Bart was the only man and surrounded by his sisters, aunts and mother for company and entertainment. And he didn't really care for any of them. The machine that he had accidentally turned on was emitting a high powered green glow that filled the entire room with bright waves. They all looked at each other nervously. MAggie finally put down her phone in order to pay attention. Marge gulped and pulled at her pearls hoping that nothing bad was going to happen.

Patty and Selma cried out in disgust and heart break as their packs of cigarettes began to disentegrate in their pockets. They were honestly close to tears. Bart stood beside the machine awkwardly not sure what to do. After all Frink had not told them what he actually had planned for all of them, or even what this machine was going to do. All he had done was bring them here. The idiotic genius.

"Bart? What are you waiting for turn it off!" Lisa shouted at her brother as she attempted to stand, for some reason she found it a little hard to...well...move...

Bart quickly switched it off and everyone paused and looked around in shock, waiting for something to happen. After all this could be anything from a give you pudding ray to a death machine. Frink wasn't the resident mad scientist for nothing after all. Everyone waited and watched each other nervously. A second went by. Then two. Then three minutes had passed and everyone let out a breath they didn't know they had been holding.

"I think that everything is alright." Lisa pipped up happily before groaning and snapping in half gripping her belly in shock as wave after wave of strange power flowed out of her core.
"Do you ever get tired of being wrong?" Bart said with irritation as he gripped his own stomach and moaned on the floor. He felt like he was pooping...did Frink really just come to have the entire family try out a weird poop machine? The sick weird cruel bastard!

Patty and Selma were groaning and coughing up their lungs in shock. They were slightly crying and Marge was almost on the floor in shock. Maggie moaned and gripped her head. The room was spinning, things were changing so fast! The entire family seemed to be affected by some strange unknown thing that was attacking all of them!

Then just like that, the weird pains stopped and a powerful new feeling began to stir and spin within all of them. A more...lighter...and gentilier feeling. Lisa gasped as she felt her back arch and something start tingling inside of her dress. She moaned and gripped the hem of it and began to play with the orange stitching before biting her lips and rubbing the back of her neck. She blinked rapidly before gasping as she saw something odd happening to her mother.

Marge was biting her thumb as the weird pleasure flowed through her. It was different compared to most anything that she had ever experienced. It was overwhelming. And it was not stopping. It made her feel good. And light. And happy. And a little slow, as if she were in a dream. The mother of three began to giggle to herself and removed her pearls and put them on the side before shaking her hips and getting a bit more comfortable in her cheap folding chair. She groaned as she felt her entire body tingle.

Bart gripped his arms and grinned to himself, for some reason they felt...well good. That was the best way to describe it. Then he realized what it must be. He was growing muscles! Slowly but steadily the flabby un defined noodle arms were becoming replaced with strong firm muscles that grew and reformed and grew again. He felt like a superhero and the size that they were getting to he could probably give that massive foriegn actor that lived in town a run for his money! Bart grinned to himself and then gasped as his body actually began to show the changes. He shot up two feet, his flab was replaced by a firmer musclular and powerful build. His eyes sharpened and his skin cleared, his teeth turned perfect and he felt incredible. Like he could tear the world apart. He gazed at himself in shock before hearing a ripping and tearing and seeing his clothing stretchd out to the extreme. It soon began to fall apart at the seams and collapse around him.

Marge gripped her forehead and gasped, she felt different, weird, and wonderful. And younger...she gazed at the mirror on the wall in the room and cocked her head. She looked younger. She looked like she was Bart and Lisa's age, her long blue hair had come out of its style and lay long and blue down her back in gorgeous ringlet waves. She cocked her head and then realized what the secondary weird thing was. Her body was changing, she wasn't just younger she was also incredibly well stacked and incredibly fit for someone that was twenty! She stood up and walked to the mirror studying herself. Her body seemed to be shifting before her very eyes!

She gripped the top of her lime green dress and pulled it down just as her breasts began to grow and swell and become larger and larger. First basketballs and then beachballs were on her chest. She gasped and touched her pink puffy nipples and moaned in delight as it sent shivers down her spine. Not a wrinkle or stretch mark on her, it had all been burned away. She looked glorious and perfect and incredibly beautiful.

Lisa was trying to keep her mind straight but she felt her chair sagging and her chest sagging and knew that something was different and wrong and wonderful all at the same time and she knew that she was slowly loosing control of her mind. She felt her dress twist and turn and tear across her body. She saw Marge stand up and walk to the mirror to gaze longingly at herself as her butt cheeks, hips and breasts grew to lewd porn star sizes. Lisa realized that the exact same thing was happening to her. She gazed down and did some quick measurements.

Marge had the butt cheeks of a watermelon that was cut in half and then glued to her backside (Or the size equivalent, Marge's butt cheeks were now absolutely huge in order to keep up with her breast size) Lisa's were more like slightly smaller watermelons, but they could still compete against Marge's. Hell the mother and daughter could probably switch underwear and not notice the difference. Lisa stood up shakiliy and gasped as her clothes seemed to disentegrate right off of her body. Literally she just moved and they burst away.

Maggie groaned and gazed down at herself as her legs grew longer and stronger. She touched her hair and felt her blonde locks slowly growing. She was growing older, she was no longer a teenager but felt the poise and maturity of an adult grow inside of her. She moaned and wiggled her butt and heard the chair creak as her mass and size grew until she was the same height and beautiful rippling body porportions of her boner rific sister. Maggie licked her lips and fluttered her eyelids as she felt her mind begin to grow hazy with thoughts of glorious glorious reproduction flowing through her delightfully changed mind. She grabbed her breasts and began to play with herself in shock. Who knew big boobs were so much fun?

Selma gasped and bent in half before rolling her back. She moaned and groaned, she felt as if she was having a massive orgasm crash through her mind and remove all sense of morality, right and wrong, she was at the mercy of her body and her emotions, she began to breathe heavily and then coughed even harder, as if her body was rejecting all of the smoke that she had breathed in during her entire life. She gasped and moved her hands upwards to cup her breasts as they began to swell, getting larger and larger, heavier and heavier until it looked like she had a pair of udders on her chest. She moaned and moved her hands over herself again and again and grinned in selfsatisfaction as she realized that she was getting curvier then her sister Marge and her niece Lisa. Of course they were already very curvy so she was on a different style.

Patty gripped her pants and shimmied her hips, her body type was nearly identical to her twins, nice big asses and fat thighs from sitting around all the time, getting rounder and curvier. Sure Marge got the biggest tits, but then again she was also the only one out of the three of them to bare children. Patty felt her dress split down the back and then rise up near her crotch. She gulped and moved the shreds of her dress aside and gazed in shock at the large firm cock that was growing there. She gulped and flicked it before moaning as she felt unbridled pleasure flow out of the erect cock. It was ludicriously huge, just idiotically big. And right underneath it was her pussy, dripping wet and aching for something to be rudely shoved into it.

The six family memebers were breathing heavily before all of them instinctively turned to look at the largest cock in the room. Bart's burning hot dick, it was practically the length of his leg and as thick around as his arm. It was huge, throbbing and seemed to be giving off an incredibly inviting aroma, one that encouraged them all to gravitate towards it.

Bart was gasping and holding onto his shaft, attempting to cover up even a little bit of it, but for some reason the moment that his sisters got to him, Lisa gripped it instead and MAggie ran her hands through his hair sending electrical shocks through his entire body. Bart dropped his hands and smirked in happiness, he wanted them to touch him and caress him and enjoy him. He moved his hands down and gripped their ass cheeks and gave them a heavenly squeeze.

"OH! Oh bart!" Lisa moaned in delight as she gripped his chin and brought their lips together and began to passionately kiss. Maggie pouted before grabbing her brothers face and turning it towards her to encase his lips. She then brought it to the next logical level by slipping her tongue inside of his mouth. Bart moaned in delight and began to lick back at her, his tongue fighting for dominance as he squeezed their butt cheeks.

"Hey! What about us?" Selma said in annoyance as she struck a sexy pose, her body jiggling in all of the right places and firm in all of the right places. Her nipples poking out delightfully far. Marge moaned and gripped her breasts before dropping to her knees and rubbing her hands and face against Bart's shaft.
"Oh I think that there is enough of my special little guy to go around." She said in happiness as she gave his erect cock a beloved mothers kiss. All of societies taboos had seemingly fled her mind. She was far to obsessed with his big delicious looking dick to care that she had raised and given birth to this enormous hunk of man stud.

"Well she is right." Patty said as she got onto her knees and hefted Bart's balls, they were the size of footballs, so large and heavy. And they smelled absolutely heavenely. She had always been a bull dyke. But the thought of slurping on Bart's gorgeous balls made her feel...entranced...she wanted to taste them. She stuck out her tongue and wrapped herself around his balls and shivered with delight. They were as perfect as she imaginged. Somehow they were every last flavor that she wanted to taste, salty, sweet, sweaty and just straight out perfect.

"MMMMMMMM." Patty moaned and groaned as she gripped her tits and began to play with them before absentmindedly rubbing at her shaft and pussy lips. She huffed and panted and rolled her hips before gasping as she felt some pre cum begin to dribble out.

"Hey Marge don't hog all of that boy cock you little slut!" Selma said as she chastized her little sister with a spank to the ass and then began to lick and nibble at Bart's shaft beside Marge. The two women grinned at each other as their tongues stuck out and began to lick and slurp up and down his downright massive cock. It twitched and shivered under their constant licking and playing. Patty moved a hand beneath his balls and hefted them. They were so delightfully large! She could practically feel the semen churning deep within them just begging to be released.

Bart was in heaven, his cock and balls were being played with by these greatly stacked sluts while he was at the same time going to town on his sisters. Maggie was mutely rubbing her pussy lips against his hands and leg, dripping already and smiling in happiness at her big brother. Lisa kept on insisting that they kiss hard and hot and wetly on the mouth, her tongue and lips moving over his cheeks until he felt sticky and damp. Her hands moved his inbetween her legs where she was dripping wet.

He slipped a few fingers into each girl and began to play and fondle their folds before steadily moving upwards and they gasped and clamped down as hard as they possibly could on his fingers. They seemed to know just where to go. Sniffing out the most sensitive of places. Senseing where they needed him to be and then exploiting that to the greatest degree. He smiled as he felt MAggie and Lisa grip his shoulders for balance, their legs felt weak as if all of their blood had gone to their tits and butts and pussies in order to increase these delightfully deviant and downright taboo and incestous feelings of delight that coursed through them.

Marge gazed in rapture upwards at her stud of a son and adorable little slut daughters. She could not believe that that was how she viewed them now but it was the truth. They were all just so hot and beautiful and she loved them all so so so so so much! She wanted to see their faces in the middle of a heavy hot orgasm that ripped and tore them apart!

She moaned and began to bob her head up and down his delicious shaft, she had not expected his meaty man sized dick to be so good. After all Homer did not take good care of his own so it always ended up tasting and looking downright gross. But Bart's was absolutely magnificent, large and long and firm and it smelled astounding. She actually took to sniffing and rubbing and moaning in delight against it, she could hardly wrap her mind around the size and girth of it! After all who was to know that he had been hiding this from her! She just wanted to eat it up!

She began to bob and gulp and lick at his shaft, Patty and Selma beside her, her hands roamed over their large curvy and big booty forms, giving little squeezes and pinches so that they would practically gargle in deep throated pleasure. Marge gazed up at Bart and saw his face tighten up as he seemed to slip his entire hand into Maggie and Lisa and rudely shove his entire dick straight into Marge's face. Fucking her mouth deep and long and loudly moaning with delight as his orgasm came to a rip roaring head!

He panted heavily as he finally began to calm down and looked at his three big bootied and heavy titted sluts with a goofy grin on his face. He found himself getting pushed over as Maggie and Lisa maneuaved their brother around so that Maggie was now slurping at his still wet shaft and Lisa was hovering over his face, her dripping wet pussy begging for a good licking. Bart smirked knowing exactly what it was that he had to do. He gripped Lisa's hips and brought them crashing against his lips and began to sloppiliy and loudly eat her out.

Marge was moaning and groaning as she watched her gorgeous children play with each other. They all looked so happy. She felt Patty spank her fat ass lovingly and then dive her face into Marge's asshole. The twins were treating their little sister like a total queen today, kissing and sucking and licking at her pretty pink pussy like the fuck starved slut that she was. And Marge was absolutely loving every second of this delightful play that the three of them were so joyously engaged in.

Patty moved around her sister until her brand new cock was pressed needfully against her little sisters mouth. Marge popped her mouth open and began to deep throat her sisters brand new cock.

Bart moaned he could not take it anymore! He needed to be inside of someone now! He moved away just before Maggie began to suck down on him. He heaved Lisa off and spun her around, his dick whipping out and around and spanking her cruelly on the ass. She gasped before moaning as he slid his cock inside of her pussy, he gasped and arched his back before really going at it. He brought his engorged cock out just a little before slamming it home. All of the other women gathered around and watched with wide horny desperate eyes as they gazed upon this glorious sack of man muscle as he made his sister his and his alone, conquering her pussy and reshaping it like clay.

Bart gasped in pleasure, he was not going to last long. Good thing he had plenty of cum to go around. He charged into Lisa's pussy and moaned as she squeezed him hard in orgasm, hard enough to get his sensitive twitching cock off right away. He gasped, he had no idea it was possible to feel that good especially with an orgasm that fast.

He pulled his dripping wet and still erect cock from her pussy. Lisa was on the ground and writhing in joy and exhaustion. Bart turned to Maggie and jumped his younger sisters bones easily, forcing her to the ground like a wild animal and starting to thrust into her. Before MAggie could even speak she found her moms lips on hers. She moaned and began to tease Marge's nipples, getting them nice and horny and sharp and shapely. She smirked as she heard Marge go into a hissing moaning fit and bucked backwards against Bart. She clamped down tightly on her brothers big incestous cock, completely not caring that they were breaking societal taboos. Her crashing continous orgasm had began the moment that his dick entered her and continued well after he cream pied and sloppiliy removed himself.

He gazed at Marge and smirked as she shivered in delight and eager anticipation.
"I have always been a mama's boy." He teased her before he stood up, pulled her shakiliy to her feet and lifted her up while facing the other women. He wanted them to see this. Marge gasped as his cock teased at her ass hole and then her pussy. She howled in delight as he speared himself.
"OOOOOOHHHHHHH BAAAAARRRRRTTTTTT BABY! My gorgeous perfect baby boy! Your cock feels so good inside of me! You are filling me up to the brim! Breed me like a big titted soft assed bitch that I am! I am a slut! A horrible desperate mommy slut! I am your milf now and forever!"

Her filthy words drove Bart right over the edge. He gripped her hips and began pounding furiously. His pace was unmatched by any other living man in the world. He groaned as her large full tits bounced and trounced and seemed to defy gravity. MArge let out a deep throated moan of lust and powerful desire. Her eager womb sucked up his semen and carted it off secretively and lovingly caressed his dick, she wanted it all inside of her where it would be nice and protected and safe. She grinned and sweated stupidily, her red face was a complete mess and she felt like she had been screwed absolutely senseless.

Bart heard a whistle as he removed his mom from his still throbbing dick, her legs gave out and she collapsed among her sweat and cum covered daughters, who cuddled up to her and began suckling comfortingly on her big breasts, her nipples tasted like fire. Bart turned to see Patty had mounted Selma and was screwing her slutty twin with a big grin on her face. She spanked her fat ass and shook it to encourage Bart forwards. Bart smirked and moved to lean Patty over farther so that she was really screwing his dumb aunt.

Bart found PAtty's pusy right underneath her dick and slide his cock right in. He began to pull out and then slam right back in, screwing both aunts seemingly at the same time, forcing Patty to keep up the pace and then bottoming out in Selma's dripping wet pussy. Bart smirked and grabbed their hips, thier big booties shaking and wiggling and jiggling with the forces of his thrusts as he slammed his cock all the way inside of her driping wet tightly gripping pussy.

Patty and Selma's groans rose in unison and pitch, their entire bodies trembled as Patty began to grope and tease her sisters large jjiggly breasts. Bart moaned and Patty howled as they both delivered their loads. The two sisters legs gave out and they collapsed into a sweaty cum stained mess. Bart sgihed and stood up in shock, his head started to clear and he wondered if he should be freaking out over all of this.

"Fascinating sctuff!" A heavy voice called out, the door opened and in walked Professor FRink who gazed at Bart and the screwed stupid women in scintific fascination. "Truly one for the ages. I had no idea that my breeding device would cut down soceital conventions so quickly and race the potency rate so rapidly ahem glavin." The nerd snorted and studied the passed out Maggie and Lisa, apparently the younger you are the less you could take of Bart's massive cock.

"Well time to release you all back into the common population then." Frink said clapping his hands hoping to get them all out. When no one moved he began to get nervous. Then scared when Bart with his new found muscular form picked him up by the front of his shirt.

"We will leave. But first I need you to make me a couple of rays you nerd." Bart began to chuckle thinking about all of the fun that he was going to have, everything was coming together.

Review. Next thing up soon. Sooner if there are reviews.
