Now if you really don't want to read this, then I suggest you don't because there is nothing forcing you to read this. This is for my and your all enjoyments. Only if you really want to read it though. So choose carefully.

Summary: Nico was young, he had just turned 15 not too long ago, so why did he decide to have Will's baby? Will was 19, and often felt like he was too old for Nico, so why did he create a medicine that would allow Nico to get pregnant? Why did they both agree they were ready for a child? Because they are in love, and that was all that mattered.

Warnings: Yaoi, Smut, Mpreg, and probably much more.

If you don't like any of this, then you should not read this, please turn back. Now! If not then enjoy!

Being a son of Apollo helped in many ways. Not only was he the most romantic lover, and an excellent archer but he was skilled in medicine to the point he almost felt like a wizard of some sort. Will, along with his siblings had made a lot of medical advances since being at Camp Half-Blood. Will himself though, decided to develop something on his own.

When he first started it he had to question why he did. It was almost sick in a way. After all, he was nineteen, going to be twenty before he knew it, and Nico was so much younger than him. So why did he start creating his own concoction that would allow any male demi-god that drank it to become pregnant? It was against all of natures laws, but that was a gift of being a son of Apollo made things like this easy to pass by. However it made Will think, did he really want this? What if Nico didn't want this?

Will sighed loudly at his finished product, it was impossible to tell if it would work on demi-gods or not. He had only tested it on some rabbits, and it had worked for them. But rabbits and people are not the same thing. Not to mention he had to factor in the god in them. What if it reacted bad in Nico's body and hurt him. There was just so much things that Will did not know, and wouldn't want to test it out of Nico. He placed a cap on the bottle and hide it amongst his personal belongings. Maybe another time, he had a date with Nico after all.

He exited the Apollo cabin and made his way toward the Hades cabin, placed at the end of the horseshoe shaped arrangement of the cabins. Of course they had placed his cabin at the end, just to make him feel more out of place. Nico has always had insecurities, being the son of Hades and all. It didn't help he had lost Bianca at an early and to top it all off nobody wanted to be around him because of his godly parent. It was just unfair, and Will hoped to help Nico through all the wrong in the world, to make it all better. Although he knew he couldn't, not really, not with what Nico has been through, but he could try.

Maybe that was why Will wanted the two of them to have kids. Kids made everything better, they brought joy and happiness to everyone's family. Will knew that Nico would claim that he wouldn't be a good father, but Will knew better. Will could tell that Nico had a protective side that would be perfect for having children. Will knew he could be a great dad, or mom, or whatever. Will knew however he had to let the thought go. There was no way he could allow Nico to get pregnant, or if he knew that Nico would even agree too.

"There you are." Nico mumbled, looking to his approaching boyfriend. He was standing on the small staircase that led into the ever dark Hades cabin, leaning against the dark door, all dressed for their date. Will had promised them to take them off Cabin grounds with the permission of Chiron and Dionysus. Will smiled lightly at his beautiful lover.

Nico was wearing a dark shirt, like he always did but this was had Camp Half-Blood printed out on it. Chiron had made it for Nico in specific along will at least five more. Since Nico was going to stay, he needed something to wear that was Camp Half-Blood. He was also wearing some skinny jeans, instead of the black pair he always wore they were white, with tears made into the jeans. Will had bought them for him, and while white wasn't Nico's color it was a gift so he still wore them. Over the shirt was one of Will's jackets that Nico had stole from Will. It was dark red and plain, but much larger on Nico than it was on Will. The materiel went down mid thigh on Nico. He was wearing his black combat boots to top the whole outfit off.

"Looking good Angel!" Will called as he approached his boyfriend, a smile on his face trying to play off the sadness that was on it not to long ago. Will himself was wearing his almost normal attire, a pair of cargo shorts paired with a light orange t-shirt along with his orange converse. It wasn't much but both of them didn't really like dressing up for dates. Even if they were going out to dinner or something fancy. Not like they would anyway, like tonight Will was taking Nico out to see a movie and that was it.

"Whatever. Are you ready?" Nico asked with a blush on his face and looked up at Will. He received a kiss from Will and smiled into it. The blush had faded but Nico was still smiling when he pulled back.

"I am. I figured we would walk there. I'm not letting you shadow travel us there." Will said with a protective voice. Even though he was almost one hundred percent sure that it was safe for Nico to shadow travel again, he didn't want to take any chances. Besides walking was good for them and they both could use the extra exercise. While they still trained, with the lack of monsters and quests most of the demi-gods were starting to get lazy. Will could not let that happen to his beautiful Nikki.

"What? I could easily take us there you know it. It's been six months since the last time you let me shadow travel. I'm sure it's safe by now." Nico insisted crossing his arms and looking at Will sharply. He wasn't mad with Will of course, he was only frustrated. The only bad thing about dating a son of Apollo is that they would always hold their 'doctors order' over you. Nico rolled his eyes but was glad for the sentiment. At least he knew that Will cared for his safety.

"I know and I'm sure you can but I worry you know. I would hate for anything to happen to you because I didn't take care of you." Will said sadly, almost hoping to guilt trip Nico into doing what he said. However that wasn't like Nico, and knew that he wouldn't win over him.

"I'm sure I will be fine. You should worry about yourself. It is winter after all. You should cover up better, aren't you cold?" Nico asked, shifting his weight from one leg to the other, shifting his hips as he did so, looking absolutely sassy and adorable.

"Nah I don't get cold. You know that, son of Apollo and everything." Will said smiling and Nico smiled back lightly. The smile was almost invisible, but Will knew from experience how to look for a 'Nico-smile'. It didn't happen that often in front of other, but with Will, he smiled more than he has in his entire life.

"You're gonna look weird in front of all those mortals." Nico told him, still stood there because Will knew that Nico was not going to walk to Manhattan. Will was just trying to delay his lover enough to get over and walk with him.

"I don't care what they think. I only care about you." Will announced happily placing a kiss on Nico's forehead.

"You are such a sap you know that. Are you going to let me shadow travel us there or not?" Nico questioned when Will pulled back.

"Alright. But if you start feeling bad in any way or starting ghostifying at all, I will personally carry you back to Camp Half-Blood if I can and I will take care of you and never let you leave the infirmary ever again! Do you understand?" Will said quickly and will worry. He may or may not have gone overboard by reaching out and grabbing Nico by the shoulders but he didn't care. Nico was important to him in everyway possible.

"Okay Will I got it. Don't go all mother hen on me." Nico teased and brushed his lovers hands off of his shoulders. Will looked uncertain for a second before nodding.

"Alright. Take us away Death Boy." Will said with a wink and grabbed Nico's hand. Nico dragged them into the shadows of the Hades cabin and before they knew it they were in the alley of Manhattan, the two of them pressed close together for a second before Nico let go of his hand and stumbled a bit. Will was back by his side in a second, hands on his shoulders once again.

"Nico! Baby are you okay!? Is anything hurting? Are you turning into a ghost? Can you speak!?" Will asked in rabid succession. Nico rolled his eyes, placing one hand on the alley wall and pushed himself up right.

"I'm okay. Just not used to shadow traveling. I mean it has been so long. Give me time and I will be fine." Nico assured him and steadied himself once again. Will nodded uncertainly, he was still worried, but did not want to seem overbearing even though he always acted that way. It was then did he notice that Nico had brought his Stygian Iron sword with him, and it was tucked under the jacket which Nico had zipped up to hide the sword and Camp Half-Blood t-shirt.

"You brought your sword?" Will questioned a little too loudly. Luckily they were pretty deep in the alley and could not be heard from the sidewalk where people were bustling around the streets.

"Of course. You never know when a monster could pop up. Just because the doors are closed doesn't mean there isn't monsters still roaming around." Nico informed him and Will smiled.

"Alright little mister paranoid."

"I'm not paranoid, and don't we have a movie to see?" Nico asked and Will nodded. He then lead Nico to the closest movie theatre. It was luckily only a few blocks from where they had ended up. Will bought the tickets for them to get in, saying that his mother had sent him money to take Nico out on a date with. Nico picked out some snacks, which Will paid for as well and they then went into the right theatre and picked out a seat in the back. There was some other people there as well, but for the most part it was empty.

The movie started not long after they sat down, since they had completely missed the previews. They didn't know what the movie was about, seeing as though they had more important things to worry about then movies, so they just picked a random movie to watch. It ended up being about Dwarves and all kinds of creatures like that. It even had a Hobbit in it. It was a good movie, but only Will stayed up long enough to watch it all. Nico had fallen asleep against his shoulder, only half of his food eaten.

Will smiled down at his cute Nico, and pressed a kiss on his forehead. Everyone else had already cleared the theatre long ago, but Will didn't want to wake Nico. He stood up to go and throw their trash away. He then returned and pulled Nico out of the chair and onto his back. Nico was a pretty heavy sleeper, which was something that Will was happy for, as he carried his light boyfriend out of the theatre. He then proceeded to walk back to camp. Will knew that it would be easier to wake Nico up to shadow travel them home, but he couldn't bring himself too.

It was an almost two hour walk back to Camp Half-Blood, in the dark of the night but Will wasn't scared. Not for him at least, of course he was worried for Nico's sake, since it was almost midnight and they were walking in the countryside of New York, but again, Will didn't care. He would do anything for Nico, even if it was carrying him back to camp.

He arrived back after one in the morning. Chiron was still awake to greet them and make sure they were okay. Will assured them they were, and walked back to the Hades cabin. Will opened the door and walked in with Nico, setting the still sleeping son of Hades on the bed. He moved to undress Nico, knowing that the other wouldn't rest peacefully in bed if he wasn't wearing his pajamas. He left the t-shirt on Nico and put some black with skull pajama pants on him. Will stripped his cargo shorts, in favor of his boxers and left his shirt on. Once they both were ready, Will moved them both under the covers.

Will knew that Nico will be mad at him once he found out about Will carrying him back to camp. Despite his aching legs Will was glad that he did. He placed one last kiss on Nico's forehead before resting into the bed. The thought of his medicine still on his mind, for it had never left. He could not stop thinking about having a child with Nico, and he knew it would haunt him all night. Will gave one last sigh, before falling asleep.
