Stiles was surprised that Derek hadn't brought up the idea of kids, especially since he grew up surrounded by a rather large family. Two and a half years into being married, Stiles was over the moon at being with Derek, but part of him still wanted more. After a trip to Deaton, Stiles was reassured that it was possible under the right circumstances, but considering Stiles' rather standard anatomy, said circumstances would need more of Derek's involvement. So, Stiles being Stiles, he was going to make sure that Derek was up for it too and then start getting said right circumstances set up. Stiles took up humming, singing, and even buying the Salt-n-Pepper album just for the one song in particular. Today, the song was on repeat until Derek either took the hint and started talking or demanded to know what Stiles was trying to get at.
Let's talk about sex, baby. Let's talk about you and me. Let's talk about all the good things and the bad things that may be. Let's talk about sex.
Derek quirked an eyebrow once he actually paying attention to the song. Stiles simply smiled at him while he continued on washing the last of the dishes. By the second time around, Stiles noticed Derek was visibly fidgeting in his seat while he attempted to read through the file in his lap. Just as the song started up a third time, Derek stood up, clearly agitated and turned off the radio with an accompanying growl deep in his chest.
"Something wrong in my choice of music?" Stiles asked with feigned innocence.
"Is there something that you would like to talk about?" Derek questioned with a nod to the radio, a frown forming on his face. He heard the uptick in the speed of Stiles' heartbeat at the question that made Derek's nerves go on edge. "This isn't your insensitive way of telling me that you're having an affair is it?"
"What?" Stiles sputtered in surprise.
"Your heart sounds like it's about to explode out of your chest and you are playing a song about wanting to talk about sex on a constant loop. So, let's talk," Derek growled. His chest constricted tightly as Stiles worked what he wanted to say in his mind.
"I want kids," Stiles began, sheepishly. "Being the fragile human male I am, I can't do the dirty work involved in actually having kids outside the fun part. But-" Derek cut up him off with a sudden roar of rage.
"So you had sex with some woman so you could have biological kids of your own?" Derek supplied. Stiles' eyes went wide at Derek's sudden leap from him wanting kids to knocking someone up in one breath. "Is it someone in the pack at least? If you chose Cora, at least the kid would still be related to me by blood."
"You think I had sex with your sister, behind your back, so I could have a kid? Then in turn would ask you to raise it as your own without saying anything to you about it beforehand?" Stiles asked in clarification.
"Yes?" Derek said as if it was the most natural thing in the world to do. "You can't get pregnant so you need someone else to have your kids for you." Stiles knew he would regret the action later, but he laughed anyway.
"Actually, I was going to ask if you would do it, but if Cora's okay with the idea, I could just as easily ask her," Stiles chortled. Derek's look of emotional constipation grew alongside his growing look of confusion. "If you would let me finish then? I went to Deaton to see if there was anything we could do. Apparently, with a little luck, patience, and time, male werewolves – ones that are born, mind you – are more than capable of carrying children."
"You want me to have your kids?" Derek asked once the panic began to drain from his chest. He looked up at Stiles from his place on the floor where he'd collapsed during Stiles' explanation with hope filling his eyes. "I've wanted to rebuild the Hale pack for so long but I never thought that it could become a real possibility."
"Yeah, I want that. I want everything with you! I was worried that you didn't want kids since you never really gave me a straight answer when I brought up the subject before," Stiles said with a sigh. He nestled himself between Derek's knees and tucked himself tightly against the strong chest. "What do you say? Want to make some babies?"
"Hell yes," Derek breathed out against Stiles' neck. "Just so you know, in addition to two sisters, I also had three brothers and I will not settle for less that when it comes to my own family."
"I think I figure out a way to manage," Stiles growled as he turned in Derek's lap and kissed him soundly. "Let's see just how lucky we can get."
