Chapter 4: What Are Sisters For? Whatever Bart Wants
Bart Simpson, age thirteen, was looking forward to his day. For one thing, he had a new dirt bike that he was planning to ride to school today. He didn’t go to school every day these days; some days, he preferred to stay home, sleep late, play video games, and shoot a load (or two, or three) in each of his mom’s holes. Or sometimes he’d go to the house next door and fuck Maude Flanders in front of her two sons. He figured since they were getting homeschooled, they ought to get some real sex education. It wasn’t like they were going to get it from their father; he had died in a T-shirt-cannon accident a couple of years earlier, after Bart discovered that the man was planning to flee Springfield with his family in the dead of night. Nobody left Springfield without Bart’s say-so, which he almost never granted.
Today, though, Bart felt like going to school. Partly to show off his new ride, and partly so he could fuck any of a variety of girls for whom puberty was a recent event and not twenty years behind them.
The other reason Bart was excited about the day was the party that was going to happen at his house that night. But there would be plenty of time to think about that later. And he’d think about school later, too. There was fun to be had right here and now.
Still in bed, Bart shouted, “Hey, Lisa! Get your perky little ass in here!”
In moments, she appeared in the doorway, still in her nightgown. The past three years had been kind to her—she’d grown a few inches, and her body was just beginning to show the curves of maturity. Her ass, in particular, was running a bit ahead of the rest of her: Lisa now had a sweet little bubble butt, and Bart made sure she always dressed in a fashion that would draw attention to it. Long gone were the loose red dresses Lisa had worn when she was eight; nowadays, Lisa’s bottom-half wardrobe consisted solely of short, tight skirts, cutoff shorts that exposed the bottom inch or so of her ass-globes, and spandex tights that showed off absolutely every detail of Lisa’s hips, ass, and crotch, including her sweet little cameltoe.
Similarly, Bart had set rules for Lisa regarding acceptable sleepwear. This morning, Lisa was wearing a black lace teddy that barely came halfway down her thighs. Bart grinned at the sight of Lisa in the immodest garment, knowing that she couldn’t bend over in the slightest without exposing at least some of her sweet little ass. And knowing that she hated that.
Bart was perfectly capable of controlling people’s minds, but he had never felt any desire to use this power on Lisa. Sure, he could have turned her into an incest slut who wanted her brother’s cock 24/7, but what would be the fun in that? That wouldn’t be the Lisa he knew: the Lisa who had lorded her booksmarts over him for so much of their childhood, who had always acted like she was better than him even though she was the younger sibling. That was the girl he enjoyed forcing to serve him with her body, reminding her every day that she was nothing more than his toy to play with.
“Good morning, Bart,” Lisa said rotely.
“Morning, Leese,” Bart said. “Time for your exercises. Turn around and touch your toes.”
Lisa had learned that there was no point in resisting or delaying. She turned her back to Bart and bent all the way forward, causing the hem of her teddy to rise up and fully expose her tight, round, bare ass. Lisa wasn’t allowed to wear panties to bed; Bart didn’t like to have anything in the way whenever he made an unannounced visit to Lisa’s room for a middle-of-the-night fuck.
“Niiiiice,” Bart said. As Lisa straightened up and turned around to face him, he said, “Now get that teddy off and get over here. Time to spread your legs for big brother.”
With only a hint of shame-induced lag, Lisa pulled off the teddy and laid it over the back of Bart’s desk chair. Bart looked at her nude body, appreciating the tiny swells on her chest: the bare beginnings of tits. Bart didn’t mind their small size; he had plenty of big-titted bitches at his beck and call, his mom and aunts among them. In fact, the three Bouvier sisters were especially chesty right now because one Friday night six months earlier, Bart had impregnated them all in a marathon fuck session none of them would ever forget.
Once Lisa was on the bed, Bart pushed her down on her back and rolled on top of her. He was already naked, and he was in the mood for missionary this morning. But that didn’t mean that he was going to ignore his sister’s sweet ass; after he positioned his cock at Lisa’s entrance and began to ease into her—eliciting a faint whimper, as his cock was almost half again as big as it had been when he was ten—he reached beneath her and got a firm grip on her ass. Then he started pumping her slowly.
“Mmm,” he said. “You’re still as good a fuck as you were when you were eight. Damn, I doubt there’s an eleven-year-old in the world who’s gotten fucked as many times as you have. I bet even the busiest child-whore in Bangkok doesn’t get dicked as much as you.”
Lisa didn’t reply, but Bart hadn’t expected her to, as these were his standard taunts. But as he started fucking Lisa in a steady rhythm, he broke out some new ones.
“You know, Leese,” he murmured in her ear, “I could knock you up the second you’re old enough. I mean, you’re eleven now, so you could turn fertile any time.”
He watched her eyes widen, then continued, “Wanna have your big brother’s baby? You’d look so cute with a preg-belly. Plus, I’d love to watch you breastfeed our kid.”
“No,” the girl whimpered. “No, please.”
“I could even just make you fertile,” Bart went on, still fucking her steadily. “I mean, I can do anything I want to your body; I could make you drop your first egg right now, and shoot a few hundred million of my sperm in there to gangbang it. Wouldn’t that be cool? You could be Springfield Elementary’s first kid to wear a maternity dress to class.”
Lisa didn’t respond; she just started sobbing softly, making Bart smile. She’d become inured to a lot of his taunts during the past three years, so it was gratifying when he could find a way to upset her.
“What do you think our kid would be like, Leese?” he said as he pumped her slow and deep. “Probably a brain like you and horny as hell like me. Maybe he’d even have my powers. I wonder how old he’d be the first time he decided he wanted to fuck his mommy? I mean, he could do it whenever he wanted, and since I’d be fucking you in front of him all the time, he’d probably get the idea pretty early on.”
Bart fucked Lisa faster now as he went on, “How old would he be before he made a son of his own inside you? And how old would that one be before he started doing the same thing? You could have a whole line of sons of sons of sons, all knocking up Mommy and making the next one the second they thought of it.”
Bart put his lips to Lisa’s ear again, panting his words as he pumped her hard. “I could make that happen, Leese. I could make that your future. Just start your fate up and let it go like a wind-up toy. Make you a breeding slave for dozens and dozens of boys. And when my horny little bastards weren’t pregging you, they’d be fucking you in your mouth, and your ass. Your life would be one long gangbang, with occasional breaks to give birth to your next rapist. Doesn’t that sound like fun?”
“Please!” Lisa bawled. “Please don’t!”
To most people, Bart’s threat would have sounded too outlandish to be believable. Even if he could do the things he was threatening, would he really do them?
But over the past three years, Bart had given Lisa plenty reason to believe that there was nothing he wouldn’t do. Like the time shortly after Lisa’s ninth birthday, when he’d found her in the back yard, playing some game involving plastic pony toys with a new friend—a little redhead named Addy. Bart had decided he wanted this cute little girl’s cute little ass, so he told Addy to take off her panties and bend over the back fence. She’d said no.
“You like ponies, huh?” Bart said. And suddenly, a big, light-brown pony appeared.
“This is your new pony, Girth,” Bart said. “You belong to him now. Have a nice life.”
Girth, his eyes glowing red, knocked Addy down, ripped off her skirt and panties with his teeth, and raped her hard with his thick cock while she screamed and Lisa looked on helplessly. Even now, more than two years later, that pony still followed Addy everywhere she went and raped her whenever he felt like it, even though Addy had tearfully begged Bart again and again to make him stop. The most recent time, her pleading had irritated Bart enough that he had given Girth a penchant for anal sex; now, Addy perpetually kept her abused asshole coated in a water-based lube, and she never begged Bart for mercy anymore.
Bart fucked Lisa at full force now, battering her cervix with his cockhead as he drove into her brutally again and again. This was the best feeling in the world, raping the hell out of his smartass little sister while reminding her that he owned her in absolutely every way.
“Here comes…my load…sis,” he grunted. “Maybe this’ll…be the one that…knocks you up…”
“Nooooo, pleeeeaaaaase,” Lisa wept.
“HnnngghhAAAAAH!” Bart shouted, ramming in deep and firing his copious load right up into his sister’s womb. Lisa bawled loudly but incoherently, too upset even to form words as her brother potentially impregnated her.
When it was over and Bart pulled out, he gazed fondly at his sister’s gaping, cum-leaking pussy. After briefly giving the matter some thought, he decided to show Lisa just a little mercy.
“Don’t worry, Sis. I didn’t knock you up…this time. But I’ll get around to it one of these days.”
Leaving his sister on her tear- and cum-stained bed, Bart left to get dressed for school.
