Chapter Text
Stiles and Derek were lying on Derek’s bed—soon to be their bed—panting, basking in the post-coital haze of their lovemaking. Stiles was still lying on top of Derek and the older man was still inside him. It was the first time that they had some alone time to actually make love.
“I never, want to leave this bed. Ever again.” Stiles panted, making Derek laugh softly. The older man ran a hand up and down Stiles’ spine, making the younger man sigh in contentment and nuzzle lightly against Derek’s chest.
It was really peaceful, right at that moment. Actually, everything has been peaceful since the alpha pack two years ago. Stiles was now studying Art and Design at Berkeley, which was a two-hour drive from home. He would be a second year student in the incoming semester roughly three weeks from now. He decided to take online classes, though, as to not raise questions the moment his belly has grown big with Derek’s child.
“I think your dad will shoot me.” Derek suddenly broke the silence, just when Stiles was almost falling asleep.
Stiles’ head snapped up from its peaceful position from Derek’s chest. He looked at the older man with raised eyebrows and said, “Why would he shoot you? He knows we’re together and he knows we have a very, very healthy sex life, knowing the frequency and length of my stay in your house.”
“Stiles, you’re pregnant.” Derek said slowly, emphasizing the word pregnant as if Stiles didn’t know that already.
“And you’re a werewolf. I don’t see how pointing out the obvious will make my dad shoot you.”
“Stiles, you’re nineteen—”
“Turning twenty!”
“Okay, nineteen-going-twenty, and you’re pregnant. With my child.”
Stiles paused for a while, blinked once, twice, thrice, and said, “Yeah, he probably will.”
“And he doesn’t even know that we mated on your eighteenth birthday. That’s technically getting married without his consent.” Derek reasoned, making the younger man think for a while. He watched as realization dawned upon Stiles; emotions shifting from understanding to sheepish, which, confused Derek.
“Actually, uh,” Stiles started and sat up, making them both bite their lower lips to hold a moan as the younger man moved. He couldn’t meet Derek’s eyes. “I told him that we’ve mated when I turned eighteen. I just, uh, forgot to tell you?” he shrugged and worried his lower lip with his teeth. Derek simply raised his eyebrows at him then laughed loudly when the younger man flushed. Stiles pouted.
“Well,” Derek started as he ran his hands up and down Stiles’ thighs, “considering I’m still alive, that’s one bullet I survived.” Stiles snorted with a cheeky grin. “I now only have to worry about the knocking you up apart before you even graduate college. How many bullets do you think your dad will put on me?”
Stiles narrowed his eyes, as if he was actually wondering how much the sheriff would shoot Derek. Then, after a few seconds of thinking he said, “Nah. I don’t think he’ll shoot you. I’m pretty sure he told me that he wanted grand kids at some point.” Stiles started caressing Derek’s chest, gliding his hands up and down his muscled form, dragging his fingers on each nipple, making the older man moan and harden inside him. “Besides,” Stiles started (and really? He could still talk while Derek was starting to feel hot and bothered again?) “I’m sure my dad wouldn’t try or desire to kill my mate.”
With the way Stiles said ‘my mate’, Derek just had to sit up and capture the younger man’s lips with his own. And round two began soon after.

Derek has Stiles pressed right against his side on the couch, asleep, as he rubbed his mate’s starting-to-swell-ever-so-slightly belly. Stiles was three months pregnant already but they haven’t told the sheriff. They tried to tell him, but the timing was always bad; either the sheriff was tired and needed rest and promised to talk when he wakes up that the couple eventually forgets or the pack needed them (or one of them) for something. They both decided that it was best that they were both going to be present when they tell the sheriff. Oh, and another reason why they can’t tell the sheriff was because of Peter. Actually, Peter is the main reason they couldn’t find time to tell the sheriff. Like right now, as Peter barreled into the front door with some shopping bags in his hands.
Derek glared at his uncle when the older Hale dropped the bags on the coffee table in front of Derek. Blocking the TV in the process. The fucker.
Peter simply raised an eyebrow at his nephew’s glare, clearly unimpressed and unaffected. Derek, then, settled on asking his uncle with his eyebrows, silently asking what the things Peter bought were. “These are stuff for the baby.”
Derek leaned forward, slowly so he would not dislodge his mate from his side, and peered over the almost open paper bag closest to him. It had a few shirts, shorts, socks and hats for a baby with colors that ranged between blue, pink, white, yellow and black. He leaned back again and looked at his uncle skeptically and said, “We don’t even know the baby’s gender yet.”
“These clothes are unisexual, dear nephew of mine.”
“Stiles isn’t even due for six months.” Derek countered.
“Pfft.” Peter started with a dismissive wave of his hand. “Doesn’t matter. It’s best to be prepared.”
It was really starting to freak Derek out because even though Peter has always been known as someone excited for a child’s birth in their family, he was never this excited that he has been buying baby stuff three months in (well, earlier than three months, actually). The earliest month he has ever bought something for a baby, before the fire, was when his wife, Amelia, got pregnant with their first child, Anthony. Amelia was four and a half months pregnant and Peter started buying everything that was needed by a baby. It wasn’t even the normal amount of baby things an excited or prepared parent bought. From a crib to what utensils the baby would someday use were bought. The freaky thing was that all of the clothes he bought were a perfect fit for his oldest. But now he was doing it again.
The first thing Peter gave them, after they told the pack of Stiles’ pregnancy, was a pale blue onesie with angel wings at the back and “Daddy’s wittle angel” written in front. It was once Anthony’s and Derek could see in his uncle’s eyes how hard it was to remember his son. It was even harder to get it out of its hiding place because it was the last thing his uncle had of his son, the one thing that did not perish with the fire all those years ago.
“The sheriff doesn’t even know yet.” Derek reasoned, once again.
Peter rolled his eyes and said, “But I do. Your mate’s pup is my nephew, grandnephew? Grandniece?” Peter wondered, since it was decided by the couple that they want the baby’s gender to be a surprise; that was why they had one name for a girl and another for a boy.
Then, as if he realized that he and their cub were mentioned, Stiles stirred and started to wake. Derek watched his mate with fascination as Peter waited for his nephew’s mate to be fully awake. Stiles blinked a few times, shut his eyes tightly as he stretched with a groan. He blinked once, twice, and then rubbed his eyes, willing the sleep away. He perked up when he saw the shopping bags on the table and leaned down to take a peak. Stiles was the only one, between the two of them, who was excited about the things Peter has bought for their cub. Traitor.
“Are these for the cub?” Stiles asked, looking up at Peter. Somehow, in the span of two years, Peter, Stiles and Lydia have become close. Lydia was able to move past the things Peter has done to her. Derek can tell that at times, Stiles still found it weird that he was more in tuned with the oldest living Hale than Derek was. He knew Stiles always thought that Derek and Peter would be more in tuned with each other, because they were blood related but somehow, because of their high intellect and natural sarcasm, Stiles and Peter got along well in the end. Especially since it has been cleared that Peter wasn’t crazy anymore.
“Yes.” Peter responded with fondness and amusement in his tone as Stiles looked at the clothes. Derek can practically smell his uncle’s smugness as Stiles unfolded, looked and cooed, and folded the clothes again then put it down on the table.
“Ooh. I like this!” Stiles exclaimed as he turned and raised a white onesie with a howling baby wolf in front, showing the article of clothing to his mate. He then turned it around to show Derek what was written at the back. ”I’m an alpha. AWOOO!” was written in black, capital and bold letters. Derek simply raised a skeptical brow, making Stiles’ smile grow wider, lean close to him to give him a peck on the lips.
After Stiles was done looking at everything Peter has bought, they all started to put them back in their respective bags. Peter picked all the bags up and said, “I’ll put these in the nursery.” making Derek’s eyes widen because he hasn’t told Stiles that the nursery has been done for almost a week now. Okay, so maybe Peter wasn’t the only one who was super excited about it. But he was (is) the father of the child, god damn it! He has the right to be ecstatic. And besides, the nursery should always be finished the earliest, right? Right? Right.
“Okay.” Stiles said absentmindedly and cuddled closer to Derek. Then, as if realizing what the oldest Hale has said, he straightened and turned his head to look at Peter. “Wait. I thought the nursery isn’t done yet?”
“Ask your mate.” Peter shouted from the top of the stairs, simply for Stiles’ benefit. Derek really, really wanted to slash his uncle’s throat for a second time.
Stiles turned to look at him with a raised brow but didn’t say anything else. He simply leaned back down and pushed Derek on the couch so that he could lie on his mate’s chest.

“OH MY GOD, WHERE’S STILES?!” Allison squealed and went past Derek when he opened the door that afternoon. Chris nodded his acknowledgment of him as he stepped inside. It was a really good thing that their mutual deal has become an actual friendship in the end. They both protect Beacon Hills from anything supernatural and at the same time, they protect each other.
“So how the hell did you knock Stiles up?” There was only amusement and curiosity in Chris’ voice when he asked.
“I honestly have no idea how that happened.” Derek replied dumbly, as he and Chris walked to the living room to see Allison talking away while Stiles stared at her, dumbfounded. It was a nice change of role. Chris chuckled behind him.
“Why didn’t you tell me you’re pregnant?” Allison asked with wide eyes, hands a gentle touch on Stiles’ shoulder.
“Because I was waiting for you to go home?” Stiles replied, as if it was an obvious thing.
“You could’ve called me.” And, oh no. Derek knows that that voice of Allison’s always made anyone feel guilty. Even him. Though, surprisingly, Stiles seemed to be immune to it.
“I wanted to tell you in person, so.” Stiles said solemnly and held Allison’s wrists, keeping her hands on his shoulders, then said with all the cheer he could muster, “Allison, I’m pregnant!” with a smile that seemed even brighter than the sun.
Derek could vaguely here a choke from behind him, knowing it was Chris trying to hold his laughter, as Allison glared at Stiles. It wasn’t very effective because Allison was (is) an actual Disney princess; even Derek can vouch for that.
“Does the sheriff know?” Chris asked as he sat on one of the smaller couches by his daughter’s side while Derek sat beside his mate to wrap an arm around him.
“Not yet.” Derek replied as he absentmindedly laid a hand on Stiles’ now slightly obvious baby bump without his hoodie on. “But we have to tell him before the week ends. Stiles has been showing the signs and symptoms. We’re pretty lucky that I was always there or the sheriff was either asleep or at work when Stiles starts dry heaving. And I’m pretty sure it’ll be harder to hide this baby bump from the sheriff.” Derek explained as his hand started to rub soothing circles on Stiles’ baby bump, making his mate hum in contentment. Chris simply hummed as Allison looked at Stiles’ stomach in awe, as if she just now realized that Stiles actually has a baby bump.
“Are you calling me fat?” Stiles asked, all of a sudden, with a pout. It was obvious that both Chris and Allison were holding their laughter.
“Of course not.” Derek replied and gave his mate’s lips a soft peck. Stiles simply huffed and crossed his arms over his chest.
“I thought you guys weren’t supposed to be back at least until three days from now?” Stiles asked, addressing the two hunters.
“We weren’t.” Chris grumbled with a roll of his eyes but everyone in the room knew that his annoyance was halfhearted.
“But then Scott called and he slipped and told me that you were pregnant.” Allison continued cheerfully, making Stiles roll his eyes and say commentaries about Scott’s lack of ability to keep a secret. “So is it a baby boy, or a baby girl?” Allison asked enthusiastically, as if she was the one pregnant; all wide eyes and bright smile.
Stiles shrugged and snuggled close to Derek. “We want it to be a surprise. Although we already prepared names when the baby comes out.” At Allison’s questioning look, he continued, “If it’s a boy, we’ll name him Greg Martin then Mary Kristine if it’s a girl.”
“After your parents.” Allison said with a soft smile which the couple returned with a nod.

“I hope your dad won’t shoot me.” Derek said for nth time that night as they waited for the sheriff in the Stilinski household living room. After finally being able to get away from Peter, with the help of Chris, they were finally able to have the chance to talk to the sheriff together. Derek was nervous because he knocked up the sheriff’s teenage son. And only son at that. Stiles was quite certain that his father wouldn’t shoot his mate.
“I don’t think he will. And even if he does, I’m pretty sure his gun isn’t loaded with wolfsbane bullets.” Stiles replied from where his head was pillowed on Derek’s lap. Derek’s face looked horrified with the younger man’s admission, making the younger man chuckle softly. “Relax big guy,” Stiles said and patted his mate’s chest reassuringly, “I’m pretty sure dad’s already been suspicious—he’s the sheriff for a reason—and he hasn’t said anything yet.” Then, as if on cue, Derek heard the cruiser on its way to the Stilinski household.
“You’re dad will be here any minute.” Derek said as he played with Stiles’ growing hair. The younger man simply hummed and snuggled closer to Derek.
A few moments passed, the sound of the cruiser getting into the driveway was heard. The sheriff came in not long after.
Derek and Stiles both greeted the sheriff as he came into the living room. The sheriff nodded his acknowledgment as he put his things down on the table in the hallway. “What’s up?” He asked, something that has become a habit already.
Derek and Stiles looked at each other, silently communicating about the best way to tell the sheriff about Stiles’ pregnancy. Derek can sense the sheriff’s curiosity as he leaned his side on the wall, crossing his arms over his chest in the process. Stiles sat up and Derek turned his body slightly so they would be both looking at the sheriff.
“There are no supernatural mishaps I have to be worried about, right?” The sheriff asked, raising an eyebrow. “Because I’ve been having the suspicion that the two of you are hiding something, I just can’t figure out yet. But I’m pretty sure you’d tell me if it has something to do with the supernatural.”
Derek and Stiles glanced at each other once more, before finally settling their gazes on the sheriff. “It kind of does, but not in a bad way.” Derek explained as he wrapped an arm around Stiles.
At the sheriff’s raised eyebrows, Stiles took a deep breath and stood up, followed by Derek, and unzipped his hoodie to show the obvious baby bump as he said slowly and softly, “Dad, I’m pregnant.”
The sheriff stared. And stared. Then laughed loudly, head thrown back, making the couple glance warily at each other. When the sheriff has finally sobered up, he said, “Seriously. I’m pretty sure you’re male, son. What is it, really? You can remove whatever it is that’s inside your shirt now.”
The couple glanced at each other once more, more nervous than before. Stiles walked slowly towards his dad, Derek followed behind him with a hand on his lower back. He raised the hem of his shirt, showing his baby bump to his dad. Again, the sheriff stared for a long moment then looked up at his son. His face was unreadable except for the clear confusion in his eyes. Stiles offered him a small smile and said, “Congratulations dad! You’re going to be a granddad!”
The sheriff swayed, ever so slightly, making the two men worry. “Sheriff?” Derek asked after a long while. “Sheriff.”
“Dad!” Stiles yelled, making his dad snap out of the stupor he suddenly found himself in. The sheriff placed his middle finger and thumb on his temples, massaging his head, as he walked towards the couch the couple occupied earlier. “You okay?” the sheriff looked at his son blankly. “Well, at least you’re taking it better than Scott did.” At the sheriff’s questioning gaze, he continued, “Scott fainted.”
“I’m the sheriff, for Christ’s sake! I don’t faint.” The sheriff replied firmly. Then, as he moved to sit down, he paused and added in a more of a squeak way, “Martin, on the other hand is a bit woozy.” then flopped down on the couch, staring blankly at the TV with wide eyes.
Stiles and Derek glanced at each other, silently hoping that the sheriff wouldn’t have a heart attack. They slowly made their way towards the sheriff. Stiles sat down beside his father while Derek sat on the arm of the couch, just behind his mate. “So…?” Stiles asked hesitantly.
“So…?” The sheriff mimicked as he looked back at his son.
“Are you okay with it?” Stiles asked slowly, now worried of his father’s reaction.
The sheriff blinked a few times, as if clearing a fog from his sight. A few more moments passed, he sighed softly and said. “I think so. I mean, werewolves exist, nephilim’s are real and you and your mom were one. I guess I’m just caught off guard that my teenage son would get knocked up. I always thought I won’t have to worry about you being a pregnant teenager.” He paused for a moment and let a few short moments of silence pass, then asked the question that has been bugging him when they told him that Stiles was pregnant. “How did it happen, anyway?”
“Werewolf.” Derek said with a raise of his hand.
“Nephilim.” Stiles quickly followed with a shrug.
“Ah.” The sheriff nodded, knowing that it was explanation enough. “What about school?”
“I’ll take online classes until the baby’s born. I’ve earned enough in the library and my blog’s starting to earn me some money, so.” Stiles said with another shrug, making it obvious that they had planned almost everything.
“Well,” the sheriff started after a few moments of silence, “congratulations on being parents.” He smiled at the two of them, warm and fond.
Both Stiles and Derek smiled widely at him. “Congratulations on being a granddad.” Stiles said to his father and hugged him tight. The sheriff rolled his eyes. Derek simply chuckled.
