Revenge of the Nerds: Bitch Sister
“I can’t believe they fired me,” Brandon thought to himself. Sure, the prototype didn’t go as planned, but it wasn’t his fault… he was close, and he knew it.
Bitter and seeking revenge for being called “crazy, self-centered and sexist,” he spends the next few months working on a new project… which will be presented to the company president – a bitch named Sarah Lodge – who takes revenge. Despite her beauty and rumors that she slept with and blackmailed him to get to the top, she laughed at him when he asked her out and blamed him personally for the failure of the three-year project.
He’s been rejected by ugly, beautiful women all his life, so he spends every waking moment taking new mind-control drugs. It was originally used to get the truth out of people during interrogations…but now it has a more sinister purpose.
During the trial, it appeared to have its intended effect for a short time, before the man being questioned began randomly removing his clothing and engaging in sexual assaults.
A friend of the janitors who are always overlooked by the big guys, Brandon has unlimited access to all of the company’s equipment and chemicals and continues to modify the drugs for new purposes… revenge.
Six months after being fired, the drug was ready. This drug has been modified to alter a person’s moral character… Basically, it alters a person’s decision-making ability to a level lower than drug addiction… but with more psychological manipulation:
-This man can’t lie (as in the Jim Carrey movie “Liar Liar”)
-A person’s body will feel the need to obey, even if his conscious mind objects to that obedience
-This guy will have a massive increase in his libido, which he actually develops as part of his master plan to get revenge on not only that bitch Sarah, but on everyone who has treated him badly over the years.
– The person feels restricted by the clothes he or she wears and wants to be naked
-He also experimented with the formula to create a drug that he believed would have potentially lasting effects on those infected (the original drug only lasted for an hour). This is something he is still very unsure about: it could last for hours, days, weeks, or even forever.
Now back home, having lost everything after getting fired from his job, he lives with his mother and his mean eighteen-year-old sister Carrie, who constantly teases him for being such a pathetic loser. While he had the brains, she had the looks. She is a cheerleader, and like most stereotypical cheerleaders, she is a bitch to those who are not part of her social circle. Deciding that he should go after Sarah and test the drug before her company fires her, he decides to test the drug on his bitchy sister.
That night (okay, it was seven in the morning, but he’d been up too late working and his whole day had been a mess) while she was sleeping, he sneaked into her room and sprayed the drug on her face. Watching them sleep is truly beautiful. A brief wave of guilt washed over him as he realized he had given potential consequences to his own flesh and blood. However, the deed was done and it was too late to speculate. His mother was already at work, working the morning shift as a hospital nurse, and he had a few hours to test his drug and, if his theory was correct, cure his sister.
After about a minute she started coughing and smelling a strong odor and when she saw her brother staring at her she sat up and yelled. “What’s going on, Brandon?”
“Good morning, sis,” he smiled, his purple pajamas barely covering his large breasts.
“Get out of here, you pervert,” she snapped, angry at his arrogance.
“I’m just giving you a new warning,” he said ominously.
“What does this mean?” she asked, staring at him, still not fully awake.
“That means it’s time for you to return to your place,” he said, hoping to do just that.
“Go away, unemployed loser,” he replied, the harsh words coming naturally to him.
“And you’re a slut,” she responded immediately. “I think that’s true both figuratively and literally.”
“Haha, my brother is smart and knows how to lie.” He said sarcastically. “How do you think that works?”
Eager to test his theory, his cock tentatively hardening in his pants, he ordered, “Show me your tits, baby sis.”
“As if,” he scoffed. “I know you’re a virgin, of course, but that’s just pathetic.”
He smiled, knowing she would spit venom at him, just as he knew she would when he followed her, but as expected, she unconsciously lifted her nightgown as she spoke. “They’re just as good as I thought they were,” he said, looking at her large, firm breasts.
When she realized she had taken off her pajamas, she looked down and gasped. “Should I strangle you?” she said, confused.
“Hold these big melons for me,” he ordered, enjoying the confused expression on her face.
“Get out of my room,” he ordered, his tone laced with venom, though she once again obeyed her brother and grabbed her voluptuous breasts.
“Okay,” he agreed happily, his years of research had worked out exactly as expected. He went straight to the kitchen, picked up a cucumber and suddenly returned to his sister, who was still covering her chest and unable to remove her hands.
“What did you do to me?” she asked, clearly frustrated that she couldn’t stop grabbing her breasts.
“Just modify your little brain,” he shrugged “It’s pretty simple.”
“I’ll kill you!” she threatened, her face turning red with anger.
“In fact, you will fuck yourself with this cucumber,” he ordered, throwing her on the bed.
“I won’t,” she replied coyly, holding her cucumber.
“Actually, why don’t you give your new green friend a nice blowjob first?” she instructed, pulling out her phone to film it.
“What happened to you…” she asked, before the cucumber could stop her question. She sucked slowly, her eyes wide with shock and anger.
He filmed her sucking the cucumber with great pleasure. After a few minutes, he said, “Looks like you’re having a great experience.”
She looked at him with tearful eyes.
“Now fuck yourself with your new toy,” he ordered.
He took the cucumber out of his mouth and continued the insults, “Brandon, you’re so pathetic. You can’t find a girl, so you have to look to your sister to get rid of yourself.”
“Oh, you’re partly right. But it’s not about leaving me, it’s about revenge,” he revealed.
“Revenge?” she asked as she unceremoniously took off her underwear.
“Yeah, you’ve been a total bitch to me your whole life, and now I’m going to show you your place,” he explained.
“My place?” she asked, stuffing the cucumber into her pussy.
“You’re just like a parrot,” he joked. “Even though you’re clearly a slut, obeying your brother will turn you on.”
“Fuck,” he said, thrusting the cucumber in and out, much to her dismay as it was actually turning her on.
“Soon,” he promised, foreshadowing that his end… was coming.
“Are you going to fuck me?” she moaned accidentally, frustrated by her inability to control herself and embarrassed that her failed brother had taken control.
“Once you beg me,” he replied, pleased to find that the drug was apparently working well.
“When hell freezes over,” she said, still unaware of her predicament.
“You’re such a boring slut,” he accused, amused by her still clueless appearance. “I don’t know how you and I come from the same DNA.”
“I’ve been asking myself that question,” she replied, still patiently thrusting the cucumber in and out of her pussy.
“It’s cute how you protest like a slut,” he replied, trying to tease her even more.
“You bastard,” she groaned.
“Fuck yourself faster,” he demanded. “Fill that pussy with your new toy.”
“Hey,” he cursed.
“Are you excited?” he asked, already knowing the answer.
“Yeah, damn it,” he admitted desperately, his breathing becoming heavy.
“Are you looking forward to fucking yourself in front of your brother?”
“Yeah, damn it,” she said, “why did you do this to me?”
“Simple chemistry,” he shrugged, “You know, the class you flunked.”
“You’re such an idiot,” she accused, angrily fucking herself with the cucumber.
“Better than that slut who fucks herself with vegetables,” he replied.
“You asked me to do that,” he replied.
“From the video it looks like you did it all by yourself,” he pointed out, then asked, “Does it feel good to fuck yourself with a cucumber?”
“Yes,” he admitted.
“Is this bigger than your boyfriend’s steroids?”
“Yes,” he admitted, then added, “When he finds out what you’ve done, he’ll tear you to pieces.”
“I’ll probably make him look stupid,” he shrugged, the idea suddenly sounding very appealing. Making bullies gay is true justice.
“He would never do that,” she said.
“Just like you’ve never fucked yourself with a cucumber,” he replied.
“Damn it,” she said weakly as her orgasm continued.
As orders increased, he said, “Each cucumber will bring you more joy.”
“Oh, yes,” she moaned, clearly a few pumps away from orgasm.
“But you can come only with my permission,” he said, expecting to see her request to come.
“Nonsense,” she replied, her breathing becoming erratic, obviously thinking this was a mental rule she could break.
He knew she wouldn’t lie, so he asked, “What gives you more pleasure, your new cucumber cock or your boyfriend?”
“Oh, God,” she groaned, her expression growing more desperate.
“Which one, slut?” he asked again, wanting to humiliate her as well.
“Cucumber, damn it,” she cried, pushing the cucumber deeper into her pussy, frustrated that she wouldn’t have an orgasm.
“Do you want to come?” he asked.
“Yes,” she cried.
“Please, slutty sister,” he ordered, preferring to have power over her this time.
“I’m not a slut,” she protested.
He replied, “That girl fucked herself with a cucumber.”
“Let me say yes,” he begged, sweat pouring down his face.
“Beg again,” he repeated.
“Please, can I come?” she begged weakly.
“You can do better,” he retorted.
“Damn it,” she cursed. After a brief pause, she continued pumping her pussy and begged, “Please brother, make your slutty sister come.”
“It’s three o’clock, bitch,” he said, still videoing his sister’s obedience.
“Please, faster, faster,” she whimpered, her breathing so erratic she thought she might pass out.
“One, two, three.” He counted quickly.
“Fu …
His cock was throbbing hard and he hung up the phone, excited to find that his formula was working exactly as he had hoped. He immediately removed his jeans and underwear as he continued to shiver with a delayed orgasm.
“Do you like to suck cock?” he asked, his nearly eight-inch cock standing an inch from her face.
She opened her eyes and looked in amazement at his cock, which was almost twice the length and thickness of her lover’s, something she was rarely satisfied with. “Oh my god, Brandon!”
“Oh my god, what?” she asked, knowing that any girl who saw his cock up close would be shocked by its size… especially on such a skinny nerd.
“Put it away,” she said, but didn’t turn around.
“Do you like to suck cock?” he repeated.
“Yeah, I know,” she replied honestly, even though she’d never had anything that big in her mouth.
“Do you want to suck me?” I asked.
“Oh god, yes,” she replied, then covered her mouth, frustrated that the words coming out of her mouth weren’t what she was thinking. “Why is what I want to say different than what comes out of my mouth?”
“The drugs will take away your bullshit filter,” he shrugged. “You always tell the truth.”
“Hey,” she said, before adding, “That’s not good.”
“Do you swallow it?” he asked, continuing to probe his sister’s slutty side.
“Sometimes, but I’d love to feel it inside of me,” she admitted, then cursed, “Damn it, Brandon.”
“How about a facial?” he added, becoming even more amused when he saw that she was confused by his answer and couldn’t stop staring at his cock.
“Oops,” he replied.
“How about taking a look at your big tits?”
“Mike loved it,” she admitted.
While caressing his penis he asked – Baby didi, what are you thinking now?
“That big snake is inside me,” she replied, then looked at him and said, “Fuck, I really can’t lie.”
“No, you always say what you really want,” he explained.
“Forever?” she asked, worried about the long-term effects.
“It hasn’t been calculated yet,” he replied, “though it is possible.”
“So I can never lie to anyone?” she asked, shocked.
“Yes,” he nodded, “Essentially you have to be nice to people all the time.”
“Alas,” he sighed.
“Now you are my slave sister,” he replied.
“Do you really want to fuck your sister?” he asked, a look of disdain on his face.
“Don’t you want me to fuck you?” he asked.
“Yeah, no, that’s a confusing question,” she stammered, clearly overwhelmed.
“Sorry, double negative,” he laughed. “I’ll make this simple. Do you want to fuck your brother?”
“God yes,” she admitted, her pussy wanted it even if her mind thought it was disgusting.
“Am I older than your other boyfriends?” he asked.
“Big.” He nodded.
“Come on, stroke it, I know you want to do that,” he offered.
“It’s huge,” she said, mesmerized by its length and thickness. “And it’s hard,” she said, holding it.
He added, “All for you, my slutty sister.”
His cock lay mesmerizingly before her and she took it into her mouth. She swirled her tongue around the thick crown of the mushroom.
He was amazed at how effectively the drug had weakened her inhibitions, and was amazed at how well she could now suck his cock without him noticing. Her mouth was amazing, producing extra saliva and creating an amazing sensation unlike the few blowjobs he had received before.
He pulled his cock back, making a loud “pop” sound and asked, “Do you like this, bro?”
“Pretty much,” he nodded, liking that she volunteered, and then said, “What about you?”
“It’s huge,” she repeated, taking it back into her mouth.
He smiled again, knowing she had made this decision of her own free will.
After a minute he asked, “Does my slutty sister want to fuck?”
Her eyes widened as she took her brother’s cock out of her mouth. “This is incest,” she pointed out, her hand still on his cock.
He laughed, “You just had my cock in your mouth.”
“Blowjobs aren’t real sex,” she replied, “she’s sucked off many guys but has only put two in her pussy.”
“That’s funny,” she laughed, asking, “Is anal sex also intercourse?”
“That’s disgusting,” she protested, but she denied it whenever the incident came up.
He smiled.
She saw his smile, realized his power, and begged, “Please don’t make me want anal sex.”
He shrugged, “As long as you’re a good slave, I won’t add these to your new terms.”
“A reality.”
“Do you want it in your ass?” she teased, her perfect ass now staring straight into his face.
“My idiot brother, fill your sister’s pussy with your big cock,” she suggested, her tone lustful.
“I don’t know,” he teased, even though he was behind her on the bed, he was amused by the fact that she was offering him her pussy without any instructions.
“Fuck your slutty sister,” she said praying that he would accept her offer, really she wanted to feel his eight inches inside her and not have to do any unnatural sex at all.
“If you insist,” he smiled, sliding his cock into her.
“FUUUUUUUCK,” she cried out, the length and width of it was unprecedented.
“Do you like it?” He already knew the answer as he sunk deeper into her warmth.
“God, yes,” she admitted, wanting more. Without even realizing she was doing it, she began bouncing back on his cock.
“Oh, you’re such a hot slut,” he groaned watching his slutty sister transform into his slutty sister.
“You’re so big,” she moaned as she bounced on his cock, finally understanding how good sex could be. She sucked cock to please her man; she had to fuck because it felt good and made her man happy, but it also brought her pleasure and joy she hadn’t known before;
“Who do you want to fuck more? Your boyfriend or your brother?” he asked, loving the quick transformation from bitch to slut.
“You, Big Brother…” she replied, building up her arousal.
“Are you my personal cum bucket from now on?” he asked, not as a demand.
“Yes,” she groaned, her breathing already becoming erratic.
“So will you respect and praise me in front of your bitch friends in the future?”
“Yeah, all of my friends would love a piece of this big cock,” she admitted, even though she didn’t know how to discuss such a topic.
She said, “I would love to fight Becky.” Betsy is Carrie’s best friend and cheerleader.
“Okay,” she said, her orgasm so close but not yet bursting.
He watched his sister bounce on his cock, loving the power he had over her, partly because of the drugs and partly because of his huge cock. He also found it weird because he knew she couldn’t come until he said she could.
Realizing that she could not come without permission, she pleaded, “Please allow me.”
“But I think incest is wrong,” she scoffed, quoting her sister’s earlier words.
“Let me say yes,” she begged, frustrated by her inability to do so.
“Come on, slut,” he ordered, watching her fall forward instantly.
“YEAAAAHHHHH,” she cried out as the invisible dam broke and the most powerful orgasm of her young sex life exploded inside her.
As she continued to cum he leaned forward and continued to fuck her, it was his own climax building.
When he realized he couldn’t hold out much longer, he stepped back, stood up, and ordered: “Kneel, bitch.”
As soon as he put his cock in her mouth, she immediately got off the bed and sat down on her knees.
“From now on, you’re destined to cum,” he declared.
Immediately, she wanted his cum. She began to bounce up and down on his big cock hungrily.
“Tell me what do you want slave?”
She jerked his cock out of her mouth, “I want your cum in my mouth.”
“Beg for it,” he ordered, jerking his cock.
“Oh, please, brother,” she begged, the humiliation still washing over her even as her saliva dripped with his cum, “fill your sister’s mouth with your cum.”
“Open it,” he ordered, and a few seconds later he was ejaculating into her mouth while the first rope hit her nose.
As the semen ejaculated into her mouth, she felt a sense of satisfaction as her sudden hunger was satisfied and she leaned forward and took his cock back into her mouth to suck back a drop of the intoxicating seed.
He groaned as she slowly milked his cock, “What a slut.”
He pulled out his penis and said, “You will never tell anyone about this.”
