Sisters History Lesson

"Mads!"

Madison's older brother was calling her over. He had the big dumb grin that he always had when he wanted to show her some ugly bug or some other thing he knew would gross her out.

She walked over to the display where he was standing. She was enjoying her time in the museum. It was air-conditioned and much less crowded than the streets of Cairo. She was also drawn to the contents of the galleries. The details of Egyptian history didn't interest her much, but the beauty of the objects collected did. She was hoping she could get some versions of the jewelry at the gift store.

Madison rolled her eyes as she walked over to Carter. He was standing by a statue of a man and a woman in the same style as the hundreds of other pharaohs that they had already seen at the museum.

"Read this." He pointed, still grinning.

Madison found the English text: "Pharaoh Amenhotep II and his sister-wife Tiaa. It was common for the pharaoh to marry his eldest sister. They were the parents of Thutmose IV."

"Barf." She mimed vomiting. "They can't really have married their own brothers."

"Yep." He smirked. "If I was the Pharaoh you and I would have to get married."

"Ew. Don't even joke about it. That's disgusting."

She turned and walked away from him. Knowing that behind her Carter was smiling. His permanent mission in life was to find things that would annoy her, and he had once again succeeded.

.....

The museum was the second day of their family trip to Egypt. There were eight of them travelling together. Her brother, her mom, her stepfather Paul, her twin stepbrothers, and Paul's elderly parents. Paul was paying for the whole thing, a fact her mom never let her forget.

Seeing the pyramids had been great for impressing her friends back home with a selfie, but the process of visiting them was unpleasant. Madison hated Cairo. It was hot, it was crowded, the men openly leered at her. She wished Paul wasn't such a dork and would just take them to the beach instead of spending vacations learning history.

It was spring break, and both Carter and Madison were away from their colleges and their friends. At heart Madison would rather be in Florida drinking and getting laid, rather than touring a giant museum, but she did understand this was a once in a lifetime opportunity.

She was looking forward to the next part of the trip. They would spend five days on a boat down the Nile. They would escape the dusty city and she would instead get to spend her days by the pool.

That night alone in her hotel room Madison was texting with her friend Chloe back home. Telling her about her day. She couldn't help sharing the same gross fact that her brother had sent.

"Totally gross fact about ancient egypt: they all fucked their families."

"Eww what?"

"Yup. brothers and sisters. fathers and daughters. they all did it."

Madison had earlier done some Googling and found that everything she had learned in the museum was true.

"No way that is true. Gross."

"Yep, know cleopatra? brother fucker."

"Vomit."

"Even more gross. they all had kids together."

"They must have been twisted freaks."

"Probs. though they kept doing this for millions of years, so maybe not that bad?"

"Do they still do that there?"

"No just history."

"Still, yuck, you should get home before you go native and lay carter."

"Dont. even. joke."

"Haha. he is kinda hot." Chloe had hinted to Madison before that she was kind of into Carter.

"Not. he smells like old cheese."

.....

The next day was more sites around Cairo before that evening they arrived at the boat. It was smaller than Madison had expected. Not some giant cruise ship, but it seemed very nice and posh.

Her mom came over with the envelope of room keys.

"Here Madison. This is the key to you and Carter's room."

"Me and Carter! We can't be sharing a room." Madison exclaimed in anger.

"Yes, that was always the plan, Maddy. The rooms are very expensive here. You and Carter have to share."

"You never told me!"

"Of course we did. It was all in the email with the details. You just didn't read it." Her mother lectured.

"Ugh. we're too old to share a room!"

"There is no other option."

The room she was sharing with her brother was even smaller than she had expected. Two beds with a thin space between them. It was also at the bottom of the ship. The waters of the Nile were just below the window outside. She was still furious as she went to sleep.

.....

That morning they toured another temple. They were starting to all look the same. Their guide announced this was a temple to the queen Arsinoe, built by her beloved husband Ptolemy. A great monument to romance, the Egyptian Taj Mahal their guide sold it as.

It didn't take long for Carter to come up to her with his dumb smirk. He had been looking things up on his phone.

"Guess who Arisnoe and Ptolemy were?" He whispered to her in the crowd.

"My guess is this is going to be gross and I don't really want to know." Madison scowled at him.

"Yep, they were brother and sister as well as husband and wife." Just like those two at the museum.

"Eww. No wonder their civilization collapsed."

"Their civilization lasted a lot longer than ours ever did. Who are we to judge?"

"Me. I'm going to judge. And I'm going to judge you if you keep bringing up creepy facts."

"It's just history sis."

He gave her a sharp pinch on the butt. She yelped as he vanished into the crowd. She was furious. She hoped they would come across some ledge she could push him over.

.....

The plan for the afternoon was to go swimming. She changed into her bikini in the bathroom. With how weird her brother was acting she wondered if she should cover herself up. Stay in her t-shirt until they got to the pool, or wrap herself in a towel. Something to keep the creep from gawking at her.

She was annoyed. It was her room. Why should she be forced to cover herself! If the perv tried to gawk at his own sister she would let him know to keep his eyes to himself.

She walked proudly out into the room in just her yellow swimsuit. Preparing the perfect insult for when her brother ogled her.

He didn't. Carter was on his bed lying in just his bathing shorts playing some game on his Switch. He didn't even glance at her as she stood there in only a few wisps of clothing.

She stood there glaring at him. As she did so, she couldn't help but notice how much of him she could see with him in only his trunks. His chest was smooth with muscled ridges in just the right places. It annoyed her. He ate junk all day, yet still looked like that. She had to stick to salads far too often to preserve her figure. Boys! Why did they get everything so easy in life?

He still hadn't looked up at her. She couldn't stand it.

"You aren't being very Egyptian," she announced.

"What?" He still hadn't looked up.

"Your sister is here in only a bikini. If you were a pharaoh, you would be paying attention."

"Oh." That finally got him to hit pause and look at her. She stood glaring at him as his eyes traveled up her exposed body.

"Creep!" She said with disgust. "You shouldn't look at your sister that way."

She grabbed her towel and left for the pool. Feeling she had won that battle.

.....

The next day was another excursion to yet another pile of stones and statues. Madison Googled this one beforehand, and was relieved to find it was not to yet another brotherfucker. Just to one of their weird gods with an animal head. They did the usual tour with an enthusiastic local guide pointing out various sculptures.

It ended at a gift shop, selling the same collection of overpriced knickknacks as all the others. It was still a few minutes before their bus left, so Madison used the time to go to the bathroom.

When she emerged, she looked around for members of her family, none of them were in the gift shop anymore. Nor could she find anyone else she recognized from their tour. She went out to the parking lot. No sign of their bus. She went back in. Maybe they were gathered somewhere inside, but no she couldn't find any of them.

She was beginning to panic. Had she been abandoned?

"Mads!"

She heard a familiar voice. It was her brother. She had never been so relieved to see her.

"Come on, hurry. The bus is waiting"

It turned out they had left without her. Only Carter had noticed her absence and got them to turn the bus around.

As soon as she was aboard she glared at her mother. "Mom. How could you let them leave without me!"

Her mother did not seem upset. "You need to take some responsibility for yourself. It's a big group. You need to try to stay with us. Now everyone will be late for dinner because we had to come back for you. You should be grateful your brother was paying attention."

Madison was furious at her mom and fumed the rest of the trip back to the river. She was grateful to her brother though. He has come to her rescue. Sometimes he wasn't a creep.

.....

In their room that night Carter produced a surprise. He had stolen one of the bottles of crummy Egyptian wine from the dining hall. He filled two plastic glasses from the bathroom and offered one to Madison. She happily accepted. It wasn't good, but she wanted a drink.

The two chatted as the bottle vanished. Madison ranted about their mother. How she ignored her only daughter, and only paid attention to scold her if she ever did anything wrong. Carter listened patiently as she vented.

Madison went to refill her glass, but the bottle was empty. What would she do now? A wicked plan developed in Madison's mind. She thought about ancient pharaohs. Her brother wasn't that bad looking after all. Maybe just this once in this place far from home she could do it. Do something to prove how much a mistake her mom had made by forcing them into one room.

"If I wasn't your sister, would I be pretty enough for you to ask out?" She asked as innocently as possible.

Carter's mind never worked all that fast, and he knew she was laying some sort of trap for him. The alcohol didn't help.

"I guess so. You're pretty cute." He eventually mumbled.

"As a boy, what part of me do you think is best?" She straightened up on her bed so he could get a good look.

"Ummm...your teeth are nice and straight," he said nervously.

"That's a dumb answer" She had suffered through many years of braces, but she had much better parts of her than her teeth. "What do you think of my tits?"

"They're uh nice."

"I think they are pretty great. The only good thing I ever got from mom." She had lucked out. Her chest was a bit larger than it should have been on her thin body, and she had learned just how much effect just leaning over had on boys.

"Let's play a game." She smiled at him mischievously.

"Umm okay." He had no idea what was coming.

"You deserve a reward for saving me today. So how about you pretend just for tonight that you're an Egyptian Prince and I'm an Ancient Princess." She picked up a scrunchy from the table and pushed her long hair through it into a messy ponytail so that it would be out of the way for what was about to happen.

She stood up from her bed and she reached out to pull Carter up from his. "Stand here" she positioned him between the two beds. He still had his usual dumb look on his face, but he did what she said.

She grabbed a pillow off her bed and dropped it in front of him. Then she knelt down in front of him. Her knees on the pillow and her head level with his waist.

"Mads we can't" He realized what she was about to do.

"I'm going to reward you Ancient Egypt style!"

With a yank she pulled down his boxers. Any idea he wasn't interested was disproved as his member popped up between them.

She gently grasped it with her hand. It was smooth and a slightly darker color than the rest of him. She kissed its tip. Carter made a gurgling noise above her.

"Don't look down." She ordered. "If you don't look, you can pretend it's some other girl."

With that she popped her mouth over the head of his cock. It tasted nice. She danced her tongue over it exploring. A bit of soap from his recent shower. A bit of sweat from the Egyptian heat.

Carter let out a soft moan as she began bobbing her head. Getting into a rhythm. She put her hands around him holding the firm cheeks of his ass as she pulled herself up and down on her cock. She enjoyed giving head. She liked the sense of control it gave over her partner.

That it was her own brother's dick filling her mouth was even more of a thrill. Doing something so forbidden. Something she could never tell anyone about was exciting. She imagined how angry her mother would be if she could see what was going on. It served her right for not shelling out enough for her and her brother to have their own separate rooms.

He put a hand on her head, trying to control her pace. She pushed it away. She did not like that. He moved his hand instead to cup her breast. That was the right place. She enjoyed the feeling of her brother's big hand groping her though her shirt.

She looked up. He was staring down at her. He was breaking the rules. He was meant to be looking away. Pretending the mouth around his cock was someone other than his little sister. She locked eyes and glared at him. She wanted to tell him off, but that was hard to do with her mouth full of cock.

She turned her attention to exploring other parts of him. She cupped his balls. Gently moving them between her fingers. Encouraging them to produce the gift she was eager to receive.

He was getting close. His hand was fondling her breast more aggressively. As his hand increased its speed, so did she. She moved her head and tongue as fast as she was able. Trying to get him to that final crest.

With an explosive moan from above her it happened. She felt his salty cream explode onto her tongue. She slowed down, trying to extract as much of it from him as she could. She then swallowed. Her millions of potential nieces and nephews disappearing into her stomach.

She pulled her mouth off and his member flopped down.

"You can never tell anyone we did that." She warned him as she stood up.

"Of course sis." He still seemed shocked by what had happened. "Umm, would you like me to do you the same way?"

She gazed at her brother. She would have loved to feel his tongue diving into the folds between her legs, but she also worried it wouldn't stop there. If her panties came off, it would be more than her brother's tongue that would end up inside of her.

She suppressed her desires and went to sleep.

.....

The next day Madison woke up with a headache. The events of the night before came flooding back. What the fuck had she done?

"Morning Mads."

She rolled over and opened her eyes, only to see her brother completely naked. His morning wood standing at attention as he gently stroked it

"Ew put that thing away, Carter. What happened last night isn't happening again."

Madison fled into the bathroom to take her shower. As the water flowed over her she reached between her legs. She was horny. Her brother did have a nice cock. What would it feel like slipping inside of her? She fantasized about that forbidden thought and she played with herself. It would be so easy, he was just in the other room.

Madison came out of the bathroom wearing only a towel. Thinking that maybe if her brother behaved himself she would grant him her ultimate reward, but to her frustration the room was empty. The punk had already left for breakfast.

.....

The final day of their trip was the great temple of Abu Simbel. Saved from the rising waters of the Nile and rebuilt on its new shoreline. It was impressive, even to Madison's tired of temple eyes. The giant statues of Ramses the Great and his family towered out of the desert.

Madison and Carter found themselves alone looking at one statue of a wife of Ramses. They did what they always did now and started Googling to find the truth that wasn't on many of the plaques.

"It's the usual." Madison announced with resignation. "Ramses had 68 kids. He married his sisters, had daughters with them, and then married those same daughters." After what had happened the night before Madison no longer had any right to judge.

"Lucky guy." Carter announced with undisguised admiration.

"Luckier than you will ever be. Last night was a one time only thing. When we are home you can never mention again what happened."

"Once we are home sure, but we still have one more night in Egypt sis."

Madison was thinking a lot about what was going to happen in their room that night. She knew what she wanted to happen. She had to be honest with herself. She wanted her dumb brother to fuck her. He might be a moron who didn't shower enough, but he was her smelly moron. Would it be so wrong for her to fuck him just the once? If it was okay for Ramses, it could be okay for her.

.....

At dinner that night Madison had another big fight with her mom. It was over something dumb. It always was. Madison and Carter went to their room with her angry. He knew from experience this was dangerous ground when his sister was this angry.

"Mom just wishes she was still young like you. She envies you. That is why she tries to control what you do so much." Carter offered.

"Naww, she's just a bitch and always has been. It's why dad left her."

"I got something that might cheer you up."

Madison did not want to be cheered up, she sat down on the bed as her brother vanished into the bathroom with a bag.

He emerged wearing a big dumb smile and a ridiculous plastic pharaoh hat on his head. Despite herself Madison grinned at how foolish her brother looked. He started doing King Tut poses and Madison giggled.

He pulled her up from the bed, hugging his sister, pulling her in close.

"I thought maybe we could play pharaoh again tonight?"

Madison knew it was wrong, but fuck it. She had already sucked him off. This was their last night stuck together in this room. Why not go all the way?

"I have one of these." Carter held up a condom, which looked like it had spent quite some time in his wallet.

"Okay. We can do it. But only from behind. So I can pretend you are some other guy. Deal?" Madison felt it was important to pretend that she still had boundaries.

"Deal!" Carter agreed excitedly.

Madison shimmied out of her shorts, and then let her panties drop to the floor. She got on her bed and buried her head in her pillow. Her ass up in the air waiting.

She felt Carter's fingers explore between her legs. A finger ran up and down the length of her pussy, before one slipped inside it. It felt great.

"You're super wet Mads!" Carter's finger had discovered her secret. She was annoyed at how her body had betrayed just how much she wanted him.

She felt him climb on the bed behind her. Her whole body quivered in expectation of what was about to happen. She felt it gently bump against her lips, and then push forward spreading them open and pushing inside of her. A part of her still couldn't believe that this was happening. That her own brother's handsome rod was sliding inside of her. A bigger part of her couldn't believe just how good it felt to be doing it with her own sibling.

He began to properly fuck her and it felt even better. There was no way she could even pretend it was some other guy. She could hear him. She could smell him. It could only be her gross older brother who was fucking her. It felt amazing. His dick sawing in and out of her was driving her wild.

She wished her mom could somehow walk in on them now. Imagine how furious she would be! How much she would regret marking them share a room!

She also thought about the thousands of Egyptian princesses that had been in her same position along this same river. Beautiful women with grand palaces and thousands of servants. Women who had only one duty in life to do what she was doing now: have her own brother furiously pumping inside them.
