New Dimension, New Rules Ch. 01

"And how!" He was breathing heavy, just like Diana. "You didn't wake me up this morning. Thank God you came home early, otherwise I'd have been in a shitty mood all day."

Diana couldn't keep up with what was happening. She wanted to throw her brother out of her room, but then she remembered. He was probably well within his right to do what he had just done. He was a man, and she was a woman, and in this universe, that's apparently how things worked. It still felt wrong to Diana, and she was disgusted by being naked with her brother in the same bed.

"Okay, you got what you wanted. Can you get out of my room now?" Surely that was within the manners of this world. Especially as it was her brother. Siblings don't have to be nice to each other.

But her brother showed no intension of leaving.

"Does it look like I got what I wanted?" Johnny asked rhetorically, and looked down at his member. It was still erect, Diana realised. It was also a lot bigger than she'd ever imagined. Diana sighed. He had just given her the best orgasm of her life. She kinda owed him, she reasoned to herself.

"Fine. Go ahead." She spread her legs for him.

"Suck it for a bit, will you?"

Oh god. "I'm not really in the mood. Can't you just fuck me some more." She couldn't believe what she was saying. Her brother couldn't believe it either, but for different reasons.

"Come here, you slut, and suck your brother's dick. I'll fuck you soon enough, don't you worry."

Slowly, clearly showing how little she cared for this, Diana got to her knees, and leaned over. Her brother's dick smelled of her pussy juice, and her nose twitched. With a gulp, she opened her mouth, and took her brother's cock.

She bobbed her head up and down on the shaft. She wasn't much good at blowjobs, never having gotten any joy from it, but her brother was happy to leave her to it, and didn't interfere.

His cock was thick, and far too big for Diana to even get most of it into her mouth. Instead she spent her time on his head, using her tongue as best she could to keep him entertained. His dick tasted sour, and she didn't like it at all, but she knew she had no choice.

"Do you call this sucking, sis?" Diana's brother asked after not much time had passed. "Come on, you whore. I know you can do better than this."

"I'm trying my best," Diana said, coming up for air.

But Johnny didn't look convinced. "Stop joking. Take my dick down your throat. All of it, the way I like it."

Diana gulped. She opened her mouth, and slowly leaned forward, enveloping her brother's shaft again. She pushed herself as far as she could, until her body refused, and she felt like she was about to vomit. She could feel her eyes tearing up, but she knew she still had more to go. It was just to much.

Johnny grabbed her head with both hands and pushed her down.

Diana's eyes bulged. She hadn't expected this, and reacted to slow. Now her nose was buried into Johnny's flesh while his cock was burrowed down her throat. She couldn't breathe, and started to panic. Johnny didn't even notice. He pulled her head back again, but just when she thought she was going to be free, he shoved her back onto his cock. She felt the hard rod go all the way inside her, then it left again. Johnny had taken over, and Diana had just become a toy for him. He started slow, fucking her throat with a steady rhythm. Every time he forced his entire cock down his sister's throat. Slowly, he picked up the pace, and his breathing quickened too. He was getting close, Diana thought. Her throat was being stretched like it had never been before, and she could taste his sticky pre-cum. Soon, he'd finish and let her be, she thought. But he kept going, ever faster, fucking her mouth till she got dizzy. By now he was pummelling his cock into her face with such force that it was starting to hurt. She tried to push herself free, but her brother was too strong.

"You're being really weird today, you know that?" Johnny said to Diana as he fucked her mouth. His voice was steady and calm, and made Diana realise that he wasn't even close to cumming yet. She tried her best to relax her throat muscles, to zone out and ignore how her entire body was screaming for freedom. She was unsuccessful.

"You suck at giving head. Pretending like my dick is too big for you. You didn't wake me this morning. And why are you home this early, anyway? Shouldn't you be at work?"

Diana didn't know how Johnny expected her to answer while he was face-raping her, when he let go of her head. She jumped back, breathing heavy. She was drooling, saliva making her whole face wet. She coughed, trying to get her brother's pre-cum out of her throat.

"What's up with you, sis? This isn't you?"

She looked up at her brother. She worried about telling him the truth, but decided it was probably the only option. She gulped, and took a deep breath. Her brother was watching her with concern, unconsciously stroking his dick over her naked body.

"Something weird is happening in the world," Diana started. "I went to bed yesterday, and everything was normal. Then I wake up, and suddenly, everyone's fucking everyone. And that's just cool, apparently. And all of a sudden, everyone thinks I'm a bitch."

"Slow down. You're not making any sense."

How to explain to him? She tried again. "In my world, sex is an intimate thing, between people who love each other. Or at least knows each other. People say no to sex. And we typically only do it when no one else can see us."

Her brother leaned closer to her, kneeling above her as she dropped onto her back. The concern in his face soothed her.

"So what, you're from a different... world?"

"Yeah, I guess I must be. None of this is normal to me. Especially this. You're not meant to sleep with your..." She broke off, as her brother started groping her tits. His face retained the same concerned look, and Diana realised she wasn't getting through to him.

"So in your world," he said slowly, trying to process the words for himself, "if a stranger came up and grabbed your tits..."

Johnny was trying really hard to get his head around what he was being told, as he slid his cock inside his sister's moist pussy. She gasped, and gave him a disproving look. He didn't seem to notice, as he slowly started thrusting himself in and out of her.

"I would push him away," Diana finally said.

"And if he asked to fuck you?"

"I'd tell him to fuck off!" Johnny was completely unaware of the ridiculousness of the situation, but for Diana it was getting hard to think. She was trying to tell her brother that where was from (wherever or whatever that was) it wasn't okay to fuck women without their consent, as he was fucking her without her consent. "Could you stop that, please?" She gave his hips a gentle nudge away, but they didn't respond, instead they kept slapping gently against her.

"Stop what?" he asked, confused.

"Stop fucking me."

"Yeah, sure, just let me finish first. But you're telling me, in your world, you can say no to a man and it isn't rude?"

"Exactly!" Diana shouted, glad that she was getting through to him at least partly.

"But what if a guy wants to get off?"

"Well that's his problem," Diana said with a directness that was missed on her horny brother.

"But why would you say no? What's in it for you?" Johnny was trying really hard to understand.

He was methodically picking up the pace, and as they talked, his hands frequently went to fondle her tits. Diana noticed he had no problems talking calmly and uninterrupted even as he kept fucking her, quite vigorously by now. She, on the other hand, was struggling to keep her breath constant, much less her voice. "What's in it for me to say yes?" she moaned. She could feel a second orgasm was slowly building up.

"When's the last time you've been fucked, then?" he asked her. Clearly he meant 'except right now'.

"It's been about..." she started, then yelped as Johnny bit her nipple. "It's been four months."

"Four months! You've been four months without sex? No wonder you're so loud. Jesus, I must be a real sissy in your world." He picked up his pace, fucking her forcefully, and Diana couldn't keep in any of the moans any more. Her brother's cock just felt too good inside her.

"Well, you're not really supposed to aaaaaaaahhhh." Her scream was loud. She was coming again. Her head went light and her body started twitching Her brother was throwing himself at her, a loud slap filling the room every time he slammed his thick long cock into her pussy. Diana grabbed her nipple, and twisted hard. Her brother's rapid motions soon sent her over the edge, and she screamed out at the top of her lungs, her feelings completely overpowering her.

The orgasm lasted for half a minute, but it felt like an eternity. Finally her body went limp, and she could feel her brother get off her. She closed her eyes, equal measures happy and disgusted by herself. She'd just been fucked to orgasm by her own brother. Twice. This was not right. And it was not right that she enjoyed it so much.

"I need your help," she said, finally, her mind in a daze. "I don't know what to do. This feels like a dream, but I'm scared I'm not going to wake up."

"What do you need me to do," her brother asked compassionately.

"Can you send me back to my world? Back to the place where everyone I walk past isn't going to grab my boobs, or ask me to suck them off?"

"I don't know how to do that," he said, and Diana could hear from his voice that he was making his usual, apologetic grin.

"Then teach me what to do. Teach me how not to say no. I saw Sydney not even hesitate to give a complete stranger a blowjob. Can you help me to be like that?"

"I guess I can try," he said after a pause. "I guess I'll have to."

Diana opened her eyes. Her brothers caring face was over her, looking down on her. So was his hard cock, as he was jerking himself to an orgasm. "What are you doing," Diana asked, her feelings of revulsion returning.

"I'm here for you, sis," he said gently, and put a warm hand on her cheek. "Whatever it takes, I'll be here with you." And with that, his penis erupted, a thick white stream shooting out, and landing across Diana's face. She forced herself not to wince. She wanted to puke. Another squirt of cum, this one hitting her lips. The next one hit her eye, and much of her hair. Still she laid still. She felt gross and humiliated, by her brother, just when she needed his support and comfort the most. She forced herself to take his cum, let herself be covered in it. It was part of her training, but her brother probably didn't even see it as that. He simply hadn't considered the idea of not cumming all over his sisters face.

Finally his balls went dry, and he gave his member it's finishing few strokes. He looked a lot more tranquil now, but still showing concern for his sister. At the same time, he inched the tip of his shrinking penis towards her lips. She gave him a confused look, which he returned in kind.

"Oh, I'm sorry. I keep forgetting. I'm just so used to it."

"Used to what?" Diana asked. What part of her role was she not fulfilling?

"Well, when you cum on a girl, it's normally common courtesy for her to lick of the last few drops. But it's fine, don't worry about it."

He started to get up, but Diana stopped him. "No, no, come here. This is what I mean. I need to learn these things. Sooner or later, I'll have to get used to it, right?" She chuckled. She licked clean her lips, trying to ignore that it was her own brother's cum she was tasting. Then she lifted herself up, and put her tongue on her brother's now flaccid penis. She licked up a hanging drop of cum, then put the tip between her lips, and sucked him clean as best she could. It wasn't something she'd ever done before, but she felt like she did an alright job with it.

"That was nice," her brother agreed. "Well done." He got to his feet and stretched out. Diana wiped her face off on her pillow, so at least her eyes were both clean. The thick odour of cum felt nauseating, but she did her best to ignore it.

"So what now, then?" Johnny asked.

"You tell me. I wouldn't know where to begin. You're gonna have to show me everything I'm expected to do in this world. And you're gonna have to do it before I get fired from my job."

"Okay," Johnny said, and thought about it for a moment. "I think we should start it easy. I'll invite some friends over tonight. They're nice guys, they'll go easy on you."

"Don't tell them anything!" Diana insisted. "I don't want anyone to know. I don't want people to look funny at me. Just, you know, invite them over, and you just give me a nudge whenever I do something wrong. Okay?"

"Alright, sis," Johnny said with a smile, and gave her a light slap on the cheek. "And don't worry about it, they really are nice guys."
