Rules and restrictions.

You aggressively penetrate your sister's cunt without remorse. The **** continues for two hours and you repeatedly release your genetics in Jessica's womb. For some unknown reason, your cock remains energetic and constantly hungry for your sister's pussy.

You partially slide your cock out, and then forcefully jab back in like a knife. As you accelerate your movements Jessica gasps with discomfort.

"Bro, please... uggghh... stop."

You firmly grip Jessica's hips and pull her inward as you penetrate more violently.

You sneer at your sister and say, "For a slutty bitch, your pussy is freaking tight!!!"

Jessica angrily looks over her shoulder and says hastily, "Dammit, bro!! You have been at this for hours!!!"

Suddenly, her phone rang and she answers, "Sorry babe, I'm not ready yet." She bit her lips to suppress the moans, "Nothing wrong. Just having...you know...one of those days of the month. Y-yes. I'll be out soon."

Jessica hung up and yells at you, "I don't want to miss my date. Hurry the fuck up and cum already!!!"

When you finally finish releasing your seed in your sister's womb for the third time. She gazes at the cum running down her thigh, "Shit, I need to start taking birth control."

Jessica put on her clothing and harshly slaps you on the face as she says, "You fucking asshole!!! You just stole my virginity!!!"

Jessica is the type of person who dresses provocatively during parties and received a lot of unwanted attention. Sometimes, in the middle of the night, you catch her sneaking into her room intoxicated. With her active lifestyle, you thought she already lost her virginity.

"That's hilarious, Jessica. You're the one who called me a virgin when you're practically one yourself." You said while laughing.

Jessica flushes angrily at your crude comments and shouts, "You damn, weasel!! I was going to give my virginity to Alex, b-but you ruin it!!!"

You grin at her sorrowful expression and say, "Damn, that was fucking hot. I mean...we're twins, and we lost our virginity together!!"

Jessica stomps with a tantrum and shouts, "You're the worse brother ever. I fucking hate you!!!" Overwhelmed by losing her precious virginity without consent she decided to threaten, "Just wait when mom hears about this!!"

Jessica storms out of the basement, and you're terrified of your sister reporting the **** to your mother.

You chase after your sister and say, "Don't you fucking dare tell anyone this!!"

Jessica made her way towards the living room and says, "Mom, we need..."

"Dear, your dress is all messed up!!" Heather shouted and examines the stain on her daughter's hair, "Is this cum?" She fearfully panics, "Tell me truthfully, did Alex **** you?"

Jessica wanted to expose your aggression, but your ability prevented her from revealing the activity. And if she remains silent for too long your mother will file sexual **** against her boyfriend.

"N-no, mom. Alex didn't **** me. When I was walking towards his vehicle someone sexually assaulted me." Jessica lied due to your command.

Heather warmly her daughter for emotional support and say, "The **** must be traumatizing. Why don't you postpone your date until you're emotionally stable?"

"B-but..it's Alex's birthday. Why can't I go?" Jessica protested and Heather explains, "Because we need to report this to the police in the morning, sweetie."

Unable to celebrate Alex's birthday Jessica ran to her room and cried on the bed. This strange turn of events baffles your mind and went to investigate.

You made your way to your sister's room and asks, "Umm...why didn't you tell mom?"

Jessica covers her head with a blanket and sorrowfully snob, "I wanted to but the words wouldn't come out."

Jessica reaches out to grab a bottle from the top drawer, and you assume she's going to use sleeping pills to ease the sorrow.

"Sis, I know you are upset, but forcing yourself to sleep isn't going to solve anything."

Jessica removes the blanket from her head and angrily glares at you as she says, "It's not sleeping pills, you stupid moron." Unexpectedly, her body shudders from arousal, "It's ugh...fertility pills."

You gaze at your sister's lustful expression and curiously wonder, "Hmmm....it appears my prior instruction to enjoy the risks of getting pregnant still lingers in her mind. Do I have some type of control over her? If so, will she do anything I ask?"

"Hey, about my chores. Can you do it for me?" You casually asked your sister.

"I miss spending time with my boyfriend and you're asking me to do your chores?!!!" Jessica screamed, and throws several books at you, "Get the fuck out of my room!!!

Suddenly a mysterious **** prevents her from harming you.

You have taken a moment to contemplate your discovery, "Okay, not all my request works, but why? Is it only related to sex?"

You intriguingly view your sister consuming three fertility pills and test out your theories again.

"Hey Jess, if you consume three pills daily for a week. How many babies will you have?"

Jessica rolls her eyes at your unusual curiosity but answers, "If you must know, I'll probably end up with triplets."

"So, I was right. It's only related to sex." You sadistically grin knowing your theory was correct and resume asking questions, "Ummm...Jess. How many babies can your body support?"

Jessica wanted to conceal the information, but a strange **** has taken control of her body and her lips automatically reply against her will.

"About six babies, but there's a slim chance of getting octuplets to maturity."

Once the information was given she regain control and faintly utters, "Why did I tell him this?"

Your theory so far is accurate but needed concrete evidence to prove your claims.

"Jess, don't you think it'd be fucking hot conceiving eight babies?"

Jessica angrily glares at you and say, "No logical person thinks that's hot. Except for a degenerate like you..." Suddenly your previous command to enjoy risks resurface, "Well, I do enjoy risks, but that type of pregnancy is unpredictable."

Jessica withdraws a few pills from the bottle and says with uncertainties, "I'm not sure how many to consume." Her eyes apprehensively stare at the pills, "But twelve should be enough to conceive eight babies. If I miss calculated, I'm literally fucked."

Before swallowing the pills your sister warn you, "James, I know taking risks is an exciting prospect, but having this many babies at once is dangerous."

You smirk at her wary expression and say, "I don't care. You're the one who has to deal with the consequence."

Jessica's hands nervously shake and say, "Seriously bro, this is fucking mess up!!"

Your heart races as you view Jessica performing an impractical act of conception, "She's actually going to do it?" Your eyes intensely gaze at her mouth wide open to consume the pills, "That's it, you slut. Take those pills and make yourself extremely fertile. My sperm is going to have a marvelous time fertilizing each ova."

Jessica consumes the pills and immediately felt nauseated, "I think I'm going to be sick. My estrogen is out of balance."

"God damn, Jess. I can't believe you actually did it." You blurt with excitement and ask, "What's the chance of you getting pregnant right now?"

Jessica gently rubs her stomach to soothe the aching pain and says, "What the hell is wrong with you?" Unexpectedly, her lips involuntarily reply, "I believe it already happens. If not, it'll eventually occur within a few minutes."

You wonder what's the limitations of your control and asks something unethical, "If you enjoy taking risks. Why not go for a dozen babies?"

Your abilities finally take control of Jessica's emotions and she says, "That's insanely risky!!! Thinking about it is making me, ughhh...so fucking wet but..." She consumed the number of pills needed to conceive a dozen but plead, "I'm at my limits. Please don't asks for more."

Seeing a devious smirk on your lips made Jessica flee, but you restrain her on the bed and say, "If you enjoy the risks so much.." You lean in and whisper, "You think having five dozen babies is exciting."

It's never your intention to have Jessica develop this many offsprings, but manipulating your sister's every decision aroused you beyond comprehension.

"Yes, I'll consume enough fertility pills to conceive five dozen." Jessica submitted, but briefly regain awareness, "You fucking asshole!! There's no possible way this type of pregnancies will reach nine months!!!"

You're now certain Jessica will perform any act regarding pregnancy, but can you make her enjoy it?

"Jess, you always dream of having a large family. The only way to fulfill your dream is to have five dozen babies, but more is your primary goal. Isn't that right?"

As you finish your statements. The information surges through Jessica's mind and rewires her emotions.

Jessica widely grins at you and says, "Oh yes, bro!!! I want to have all your fucking spawns growing inside me." She grinds her snatch against your member, "Making babies together is morally wrong, but that's what makes it so special." Giggle, "But five dozen isn't enough to keep me satisfied. Wouldn't it be better if we don't set restrictions?"

Amazed by the result, you phrase a single word, "Goddamn!!"

Jessica smirks at your expression and says, "If you want to fuck me over...." She retrieves the bottle and suggests, "Let's find out how many babies I'll have consuming an entire bottle."

Controlling Jessica to act out your perversion is an enticing experience but the concept of her having multiple pregnancies aroused you even more. No longer thinking straight and running on pure adrenaline. You decided to ignore your guilty conscience and enjoy the moment.

"Ummm...can you overdose on fertility pills like a **** addict?"

Jessica's body shiver as she replies, "Since having five dozen babies is already dangerous," Giggles, "Guess it doesn't matter if I end up releasing all my ova for you to fertilize." She sadistically grins, "Do you really want this, or do you have some kind of twisted agenda for asking?"

"I like seeing how large your stomach will get." You admitted and mischievously use your ability, "You love taking risks, but nothing turns you on more than having an extremely large pregnancies. Matter of fact, you don't care if it overwhelms your body within a few days."

Even though you use your ability to manipulate Jessica's emotions, her logical awareness remains intact.

"I do want my stomach bloating like a balloon, but I doubt it's possible." Jessica said and you asked, "Why not?"

"That's not how pregnancy works. Even if you fertilize all my ova, bro. The embryos need at least two months to develop. After that, there's going to be a variety of complications." Jessica explained and then asks, "Do you want me to go through with it or get an abortion?"

"No abortion." You replied gleefully.

"Alright, no abortion." Jessica teasingly winks at you and says, "I just remembered something in health class. There are other methods we can use to complicate development."

"How?" You promptly asked.

"Well, there are several factors, stress, smoking, and drinking." Jessica said and sadly sprout, "Having stress is simple, but I don't smoke or drink."

You manipulate Jessica's perception and she restates, "You're right, bro. I excessively smoke and drink ****. I'm certain the pregnancies will end prematurely."

"How soon will that be?" You abundantly asked.

"It depends. It could be a week or a month. We don't really know until it happens." Jessica informed and you sigh with disappointment, "Would be nice to actually know when."

"I promise, the pregnancies will be as unhealthy as possible." Jessica reassured me and then warned, "It might even put my life at risk."

It seems the more you used the gift, the stronger it has on your sister's behavior. But there's something else you wanted to test out. Can a promise be overwritten with a different promise?

"Sis, you promise not to break your words?"

Jessica's eyes dilate as your ability sink its way into her subconscious.

Jessica regains awareness and says, "Yes, I promise to allow the pregnancies to overwhelm my stomach."

You deviously grin at her replies and asks, "Is there a way for the pregnancies to have complication within two days?"

"The only way to accomplish that is to accelerate development." Jessica replied and pause briefly to think of a solution, "Can your ability do it?"

"I never tried it before."

Jessica guides your hand toward her stomach and says, "Give it a try, but let's skip everything and go straight to nine months." She smiles at your wary expression and says, "You wanted to see a large pregnancies, right?" She nibbles on your earlobe and whispers, "I have never been a good sister. If you want ****, this is your chance. Fucking up my stomach is practically the worst punishment."

You hesitated on using your abilities and Jessica decided to insult you, "You're all talk but when it comes to making a serious decision, you don't have the courage to actually do it. But I must confess, you're not a complete idiot. Manipulating my emotions is pretty smart, and now I can't stop thinking of having a large pregnancies."

"Give me a little of your abilities, and I'll do something you'll never forget." Jessica demanded and you curiously asks, "Like what?"

"Don't you learn anything from health class?" Jessica scorns you and says, "Sometimes a woman has twins due to an ovum splitting embryos. If you really want to screw me over. Manipulate my ova to continuously create dozens after dozens of embryos." She wickedly grins and resumes explaining, "With this method, you don't even need to accelerate the pregnancies. All you need to do is cum inside, and wait a few hours."

You're concerned but witnessing your sister developing your spawns to their limits aroused you.

"How large will the pregnancies be?" You asked and Jessica smiles as she replies, "My stomach only has a certain amount of space. However, we can get the pregnancies as large as possible." Giggles, "But if we're not careful, it's going to burst." Your influence echoes in her subconscious and she says, "I don't mind if it did though."

Jessica's mind snaps to reality and pushes you off the bed, "W-what the fuck did you do to me?" She hectically screams remembering the promise, "Oh my god, you made me desire a fucked up pregnancy."

"Relax, I was only playing a practical joke." You defend yourself. But at this point, it's doubtful your sister will believe you.

"You fucking liar!!! You didn't even give me a choice for abortion, and deliberately asked to bloat up my stomach like a beach ball!!!" Jessica frantically shouts at you.

Suddenly, a bright light blinded your eyes. When you regain focus, you saw your sister frozen.

You wave your hand in front of her face and ask, "Hey Jessica. Are you alright?"

"She won't be able to hear you." A mysterious voice said in your mind.

You examine your surrounding areas and ask, "W-who is there?"

The mysterious voice chuckles, "It, god. Do you think everything that occurred so far was a part of your experiment?"

"Alright, I do recall having a crazy dream. Can I ask, what's your motive for giving me this ability, and what are the rules?"

"Right to the point, huh?" God chuckles and replies to your curiosity, "I bestow upon you the (voice of persuasion) and you can use it on anyone. However, I limit your influence to some degree. You cannot make someone fall in love with you, or do your daily errands. Regarding pregnancy, there's no restriction, but you can only make them enjoy the conception for a brief moment. For safety precautions, anyone you control cannot expose your actions, or harm you in a severe way."

"Hey, if you're so powerful. Why can't you make me control their emotion?"

"Good question, young man. It's simple. The last person I give full control bored me to ****. Hopefully, giving you partial control will be more entertaining. Don't worry, the more you use your ability, the longer you can control their emotion, but you want it permanent. You need to figure it out yourself."

Time resumes and your sister shoves you out of the door, "I don't have time for this!!! Get the fuck out!!!"

You sigh and went to the kitchen to grab a soda, but your eyes leer at your mother, "Damn she's hot with an apron on."

Knowing where your abilities came from and the rules that apply. You can't help, but indulge yourself.

"Hey, mom. Can you remove your apron?" You asked behind her.

Your mother turns around and sneers at you, "James, what the matter with you? I'm your mother, for god sake!!"

Soon, your mother unstraps the lace and disrobes herself. To your amazement, she has nothing underneath.

"Damn, she's hot. Should I take advantage of her?" You contemplate with yourself.
