Disclaimer: I don't own Yu-Gi-Oh; it is the creation of Kazuki Takahashi. This plot isn't mine, just adopted it from Dragon. I just thought what the hey, I can give it a try and all. Besides, it sounded fun.

Warnings: Lemon in occasional flash backs, m-preg and some language.

Couples: Seth x Atem (Scandalshipping), Seto x Yami (Prideshipping)

Notes: The past will be in italics, and present day will be in plain font. Thoughts will also be in italics, but they will be marked appropriately. And I have a good theory on how the pregnancy happened too. You'll see it in the fic. And how Yami was able to still be pregnant after 3000 years. It's really cool if you think about it.

Ancient Egypt

"Atem…" Seth breathed for a moment, looking at the smaller form of his Pharaoh, and cousin. He wasn't sure if he should continue or not. The other didn't seem to object at all. It just was just almost wrong because as a priest, he was bound by laws of celibacy.

"Seth, don't worry about it… I am the Pharaoh after all. I make the rules, and I won't punish you for this. You don't see me as others do as it is…" Atem smiled as he traced his fingers along Seth's jaw line.

"How can I? I'm one of your highest ranking priests… that and I have known you for most of our lives. If this isn't right, I don't know what is… I just don't want this to end…" Seth replied, lying next to the smaller.

Atem just nodded before moving to kiss Seth. If this was so wrong, just let Ra smite them now. Or if he was displeased, something else could occur. He knew that Ra was all powerful. But right now, he didn't think much about the god at the moment. And in turn that could be a bad thing to do.

Seth returned the kiss, eventually that turned a little heated and he moved his hands down Atem's sides slowly. This just felt so right… no one at all could ruin this moment for him. And the best part, they were all alone.

The young Pharaoh just closed his eyes in response, a light shiver moving through his slender frame. He didn't mind this at all; instead he just let Seth continue his actions, not protesting in the slightest.

"Are you sure you want to do this?" Seth asked before he proceeded.

"Yes… I'm sure." Atem replied, looking up at the taller priest.

Present Day

Yuugi, Honda, Jou and Anzu were all in the same biology class, learning about the reproductive habits of certain animals. And today they were learning about the sea horse, which seemed to be a rather interesting animal to some of the students.

"Now today class, we are going to be discussing the sea horse. This incidentally is the favorite sea creature among women." The teacher spoke after tapping her ruler against the desk.

Yuugi watched on in amusement before turning his attention to Jou and Honda who were of course sleeping through the class. Luckily this was the last one of the day, and then finally they could look forward to the start of the weekend. And even better, tomorrow was also the start of a new tournament that Seto had planned.

"I don't see what is so special about the sea horse…" Yami muttered, putting his head against his desk. It had been a few weeks since he got his own body, but lately he'd been feeling rather strange.

"The sea horse is favored among women because it is the male that gets pregnant. She lays her eggs in a special pouch on the male's front, and then 7 weeks later he actually goes through labor and gives birth to his offspring." The teacher explained, earning a few giggles from the girls and some grumbles from the guys.

Anzu was one of the few that didn't giggle, but that didn't last long. She looked at her friends and broke out into an all out laughter fest. She couldn't picture any of her friends pregnant, and if the image crossed her mind, she ended up laughing again.

"Good Ra… do you even know what you're laughing about?" Yami asked, managing to look at Anzu.

Seto looked at Yami for a moment; he noticed that he had been acting rather strange as well. But he'd ask him later, right now he just had to play it casual. Pretty much like he always did. Put on a cold, heartless façade for now and then check on Yami later on.

"Yami, I was just thinking about what would happen if you guys were pregnant. You sure you're alright, you've been moody lately." Anzu asked, she was aware of her friend's mood swings as of late.

"I'm fine… just a stomach bug." Yami replied, putting his head back down on the desk. He closed his eyes for a moment and put his arms on the desk as well.

Oh sure Mou Hitori no Yuugi…you're fine. Then how do you explain getting sick before lunch? Sure the school lunch sucks but you never threw up before… I'll have to see Isis about this later… Yami thought to himself, and luckily for him he put up a few blocks so Yuugi couldn't hear him.

"If you say so. Although I never have seen you get sick before lunch…" Anzu started, putting her hand on Yami's shoulder.

"Anzu, he said he was fine. I'll talk to him later alright?" Seto started, glaring at Anzu for a moment. Of course she backed away rather quickly; almost everyone did under Seto's gaze.

Yami looked up at Seto with an almost grateful expression. A small smile crossed his lips, although he didn't feel like it. This was still all too weird for him. He never got sick in his life, or rather not in this life time since he got separated from Yuugi. After a few moments he stood up and excused himself for a moment.

"Be sure you take a hall pass!" Their teacher called out, watching Yami leave with the hall pass in hand. Seto soon followed him; grabbing a pass as well. "Mr. Kaiba, you can't leave!"

"Hn, funny it appears that I already am leaving." Seto replied, giving the teacher a smug look before walking out after Yami.

Yami made it as far as his locker before panting lightly. His face was flushed, and his crimson/ violet gaze was duller than usual. Basically his entire expression was uncharacteristic for the former Pharaoh. He went to one knee, totally confused on what was happening.

"Yami… what happened?" Seto asked, letting his façade melt for a second. No one else was out here so he can't get berated for seeming soft. Although the CEO did care a lot about Yami.

"I'm not sure Seto… I've been feeling like this for about two weeks now." Yami replied, looking up at the taller CEO.

"I see… and how long has it been since you got separated from Yuugi?" Seto started, holding his hand out to help Yami back up on his feet.

Yami took Seto's hand graciously before standing up again. He then turned to look the CEO in the eye. He was trying to remember, it's been about a month or so. But he didn't see what that had to do with anything. Then again he had been having these symptoms since then.

"About a month, but the symptoms just seem more evident now… I was going to see Isis after school about this. She'd know." Yami replied, putting his hand on Seto's shoulder.

"Love, you know I don't believe in her mumbo jumbo about the past. She'll probably just say that you aren't used to having your own body. Or that you haven't built up immunities yet and it's just a flu bug. Why don't we go to an accredited doctor?" Seto asked, looking into Yami's eyes for a moment. But his expression hardened once he heard the door open.

"Kaiba shouldn't you save that for after school? I swear… if the principal knew what you two were actually doing…" Jounouchi started, grinning as he walked up to the two.

"Puppy this isn't the time or the place. Why don't you just go crawling back to your little friends?" Seto spoke this time.

"Well tell me what's wrong with Yami." Jou replied, crossing his arms as he looked at both of them. He did notice that the former Pharaoh did look a little green around the gills.

Yami looked at Jounouchi for a moment before moving next to Seto. He didn't even know how to answer that truthfully. Mostly because he didn't even know what was wrong with him.

"I don't even know. We're going to get checked out this afternoon. So if you don't mind, can we go now?" Seto asked, getting rather irritated with Jou's antics right now.

"Yes you can go. Don't do anything I wouldn't do!" Jou grinned before walking down to his locker.

Yami shook his head before walking down the hall. He and Seto had a lot to do in just a short amount of time. Because after they saw Isis, then they were going to dinner. So he had to find an appropriate outfit.

"I'm sorry Seto…" Yami started, looking up at him for a moment.

"Don't worry about it. Let's just get this checked out." Seto replied, walking out of the school with Yami not too far behind.

About an hour later at the museum Seto and Yami finally met up with Isis, they were both still wondering what exactly was going on. Perhaps she could give some insight, especially since she seemed to know a lot about Yami's past. That and she was present when he got his own body.

"Ah, Seto Kaiba. I expected you here this afternoon." Isis started only to cause the CEO to roll his eyes.

"Isis will you stop that already? We have a problem. Yami hasn't been feeling well at all for the last few weeks. Can you enlighten us on what the problem is?" Seto asked, crossing his arms over his chest.

Isis closed her eyes in thought for a moment, trying to think of all the possibilities. Then she reopened them and looked Yami over, but she didn't see anything physically wrong with him. No major changes, at least not yet.

"I can't be sure. Can you stand still for a moment?" Isis asked, moving her hands over the former Pharaoh's sides for a moment. Then she moved one hand over his stomach, and her eyes opened up wider than normal. I never thought that he would still be in this condition after so many years… but apparently it is possible…

"Well, what is it?" Seto asked again, almost growling when he saw Isis treat Yami like that. Or at least when she moved her hands over his sides and stomach. If she went any lower…

Isis looked at Yami then at Seto. A light smile crossed her lips, before digging something out of her dress pocket. It would make this easier for everyone, especially for Yami. Once that time came, it would not be easy on him at all.

"For one, I want to offer my congratulations. This is very hard to explain… but the both of you are going to be parents in about 8 months." Isis replied, smiling as she stood back.

"That's impossible! Men can't have babies and you know it." Seto protested, looking between Yami and Isis. This was just some hoax… right?

Yami just stood there, just as confused as Seto was. Now this was starting to sound like the film that they were watching in class. Male seahorses created their own offspring even gave birth to them. But how in Ra's name was he going to do that?

"Normally, but remember this is Yami's new body. As Pharaoh, it's believed that he and his high priest had… relations. Apparently he got pregnant before his soul was sealed into the puzzle but he wasn't aware of it." Isis started, only getting a look of disbelief from Seto again.

"Right… and I am the king of Spain. Then tell us how he was able to get pregnant. Men can't carry a baby like a woman can, let alone give birth to them" Seto protested.

"Apparently the Pharaoh had some odd abnormality that allowed him to carry a child. So Yami has the same thing, since he is the Pharaoh. Only in a different body." Isis answered.

Yami blinked, but finally he got up enough courage to ask the question that's been weighing on his mind. Isis wasn't answering Seto's questions as it was. He just hoped that she'd answer his.

"Isis… tell me how is it possible that I can be pregnant then. I might be the Pharaoh, but I'm still confused about something. Wouldn't the child have died?" Yami asked, a slight frown crossing his lips.

"Yes… but when you sealed your soul away, the spirit of the unborn child was sealed away with you. So in a way it was in suspension for the last three thousand years as well. But now that you have your own body, expect the pregnancy to progress quickly over the next few weeks to catch up to where you should be now." Isis replied.

"How far along was the Pharaoh then? If he didn't know it, I would think he'd be a few weeks along." Yami asked, the frown not leaving his face.

Seto put his hand on Yami's shoulder; the curiosity was getting the better of him too actually. He did want to know how far along the Pharaoh was, that and how quickly the pregnancy would be progressing.

"The Pharaoh was sealed away in the puzzle apparently a couple months or so after the affair with his priest. So from my calculations, he's already a month along. So actually over the next two weeks, you will go from one to three months." Isis started, looking toward Seto before directing her last statement toward Yami.

"I see. But will the rest of the pregnancy go this fast, or will it go the normal pace from here on out?" Seto asked, noting the look of worry in Yami's eyes. He wasn't sure how his body would react to such a quick change.

Isis shook her head, then she handed the bottle that she had in her hand to Seto. She smiled a little toward the two after she did so. She knew this would make things a little easier anyway.

"It will only be the two weeks. After that, the pregnancy will go at the normal rate. I just suggest that you take it easy, my pharaoh. And this bottle that I'm handing you has something that could help you through this. It won't cure the morning sickness, but it will help lessen the symptoms." Isis spoke softly.

"Thank you Isis. And we'll be sure to contact you if we have any questions." Yami replied, smiling toward her for a moment.

Seto nodded, and then both of them watched Isis as she turned to go back to her office. The next few weeks would definitely be interesting to say the least. But could they handle it? Or would Yami crack before 2 weeks was up? Only time would tell.
