Knocked Up Sunshine

Chapter 10 - The Mother's Nest

The Graduation day finally comes for the high schoolers in the Hale pack. Stiles is seated between his father and Derek in the Beacon Hills High School's auditorium. Derek's arm curls protectively around his mate's shoulder, as the principle delivers his speech.

"I almost forgot how boring he is," Derek whispered to Stiles' ear in mischief. Instead of paying attention, the man is busy stealing kisses from Stiles, making the human giggle.

"Derek, stop it! You'll get us kicked out," Stiles complained, yet grinning and leaning into Derek's touch.

Stiles looks adorable in his graduation gown, happy and big with his pup, Derek can't resist him even if he tries.

Lydia is valedictorian, at no one's surprise. The pack claps and whistles loudly as she walks up to the podium. She delivers her speech with confidence and grace. Stiles winks at her when their eyes meet, and she smiles proudly at them.

Finally, they start to call the graduates name one by one to receive their certificates.

Derek turns in his seat to face Stiles, warm hand gently rubbing his mate's heavily pregnant belly.

"You sure you're up for getting up there? I'm still concern about the stairs."

"I'll be fine, Babe, it's just couple of steps," Stiles rolls his eyes fondly at his Alpha's overprotective streak, "I won't mind if you wait for me on the other end though."

In which, of course, leads to Derek making a scene by gallantly stepping up before Stiles reaches the stairs after receiving his diploma and swooping Stiles off his feet carrying him down.

"Derek!" Stiles gasped, face burning red as every eyes in the room set on them, "what are you doing!?"

Derek ignores him to stare back at the audience, looking way too smug for Stiles' liking. When he passes a group of girls gawking, the man wolfishly grins, "Lost your chances, Ladies, he's mine now."

Stiles groans and hides his face on Derek's shoulder whimpering in self-pity, "Can I just combust and disappear now? I believe there's a limit of embarrassment a human body can take, and you just made me surpass it."

Stiles is getting cozy on the Hale house's couch, watching Tom & Jerry on Cartoon Network and trying with all his might to finish his dad's recipe from Hell, nutritious smoothie. Derek made it for him and insisted for Stiles to ingest every last drop. Stiles almost wanted to cry when Derek handed the glass to him. This is it, this gnarly mixture is the universe's punishment for all his wrong-doings.

Stiles is two torturous gulps away when Lydia, Erica, and, Allison come joining him on the couch.

"When do you and Derek plan to get married?" Lydia said nonchalantly.

The last gulp of the smoothie gets down the wrong pipe.

"Excuse me?" Stiles squeaked after almost getting choked to death by Evil. This is what the smoothie is, Evil in a form of liquid.

"I assume after the baby is born?" Lydia continues.

"We, um," Stiles gapes, blushing madly, "Yeah, that's what we planned."

"Hmm, spring wedding. Perfect. We're gonna help," Lydia said, flicking back her shiny strawberry blond hair.

It's not a question.

"Sure..?" Stiles responded, because why not. The initial plan is just going to court to have their marriage legalized, followed by a family dinner in some fancy restaurant in town. It's not like they're opposed to have a beautiful wedding to remember, it's just that they acknowledge they're going to be too busy with a newborn to plan something outrageous. Besides, they're already mated and soul-bonded. Practically, they are tied together for the rest of their lives.

Allison rubs his back like she tries to soothe him for what's coming next, Erica takes the glass out of his hand and puts it on the coffee table in front of them, and Lydia opens up her pink bedazzled notebook while talking miles per minute.

"I think it'd be best to have it here, we thought you would prefer that, especially with a newborn baby. So I am personally considerate enough to lower my expectation about the choice of the venue. But the other subjects, I refuse to have the less than impeccable perfection." She looks at Stiles daring him to say otherwise, so Stiles just nods absently, because his survival instinct tells him not to deny this woman anything when she looks like that.

Lydia seems satisfied by his consent, as if Stiles just gives her permission to take over the world, which she probably will.

"Family and pack only, you're welcome. Forest theme, gardeners are already contacted, I already have the design. There will be no living animals though; I don't care how low Scott grovels on the ground. The wedding cake is raspberry infused, with lemon frost, and it's beautiful and Isaac loves it so we take it. I have Derek scheduled for fitting tomorrow, you'll do yours after the baby is born. The tailor confirmed to finish yours in two weeks time, I have this vision of you to wear–"

"H-Hold on, just hold on a minute, Lyds! When did you guys start planning all of this!?"

"When we were planning for the baby shower. Killed two birds with one stone."

"You have my wedding plan all fixed in a week?"

"There are three of us." And she's Lydia Martin, Stiles can hear that part left unsaid.

"Does Derek know?"

"He gave me his credit card."

Stiles can only imagine what his poor fiancé had been through.

"Now, I know Derek keeps reminding us a million times not to stress you out," Lydia rolled her eyes, "but I need to confirm some lists. Just say yes or no," Lydia clicks her pen and starts raining down question lists from her notes.

Unlike the Alpha, Stiles doesn't have any credit card to save him. The pregnant human whimpers thirty minutes later, because goddamn the list is endless. Thankfully, Derek senses his distress and quickly comes to fetch him, eyes flaring red in warning to the girls to cut it out.

Less than a week from labor, Stiles is as cranky as a cat from hell.

He's always hot and sweaty though it's still freaking winter. All his joints hurt. He waddles instead of walking. He's a size of a whale, nothing fits him anymore; now he only wears pajama pants and Derek's old sweaters. He wants to pee all the time. He's hungry. He's horny. He's miserable.

He used to love to be in a puppy piles with his pack, but now he barely stands to be near anyone but Derek. He's emotionally unstable, happy for one second then suddenly angry the next. The pack, of course, tries to be understanding. They'll do anything to make him feel better even just a bit.

Stiles always feels guilty afterwards for all the attitude, but he can't help this raw needto be just left alone and hide, preferably in the arms of his strong chosen Alpha.

Mmm, his Alpha, on the other hand…

His Alpha is perfect.

Stiles has chosen well.

He has chosen the best strongest Alpha to breed him. He's wet down there just dreaming about the gorgeous werewolf. Derek's touch can melt him and send him ablaze. That fat knot could impregnate him as many times as it wants, Stiles would take it. Stiles would give Derek family as big as the Alpha desires and deserves.

Because Derek is loving and caring, showering him with affection and full devotion. Derek is warm and safe. Derek means kisses, hugs, sweet names, and getting him strawberry ice cream with salted pretzels and candied peaches in the middle of the night and Stiles loves him so much.

Derek is the father of his baby, and just the thought of him near makes Stiles content. He wants Derek, needs Derek here with him, always.

Stiles is sleeping buried under the thick warm cover of his and Derek's bed when he's woken up by small kisses on his face. His Alpha's handsome face is the first thing he sees when he opens his eyes. The wolf's strong yet gentle hand cups his swollen belly, where their son is still sleeping.

"Hey, sorry to wake you," Derek said between kisses.

Intense love and affection burst in him at the sight of his man, Stiles hums happily and snuggles closer. He then realizes Derek is already showered and dressed for the day.

"I have to head out for a while," Derek said just as Stiles gets the idea.

And the pregnant human hates it. He just has to have Derek close all the time.

"No," Stiles whimpers into Derek's neck, "Stay."

Derek wraps his strong arms around his suddenly distressed mate on impulse, "Baby..."

Stiles whines, "Don't go."

"Sshh, it's just for few hours, Sweetheart, I need to settle things at work before my maternity leave, remember?"

Stiles looks up at the wolf with hopeful eyes, "Then you won't go again?"

Derek kisses his forehead, "I'll be all yours."

Trying to beat the silly pang of loss with logic, Stiles nods and hugs Derek tighter before letting go.

Derek kisses him goodbye and leaves. Stiles locks the bedroom door after him and returns to their bed, trying to fall back to sleep.

He gives up after an hour of restless turning. He just can't relax.

He gets up and spends few minutes just glaring at the bed, trying to figure out what is wrong with it.

Stiles moves to the closet and starts to gather all the spare bedcovers, blankets, and pillows they have. He throws them on the bed and stares again, visioning of the bed situation that he wants.

Then he starts working.

He spends some time setting the bed covers and blankets into a huge thick disheveled pile. After he finishes, he buries himself into the pile, pushing his head into the pillows he surrounds himself with. He sighs, closing his eyes and tries, again, to fall back to sleep.

The sunlight reaches his eyes and it's bothering him.

It's too fucking bright in here.

Stiles growls and grudgingly gets up again. He pulls down all the window curtains, leaving their room in the dark.

He comes back to bed and lies down under the pile again, closing his eyes, finally getting back to sleep.

After a moment, glassy brown eyes open up glaring at the ceiling again.

He can't sleep.

Stiles whimpers in misery, he doesn't know what is wrong, he is just so uncomfortable.

He doesn't like the pile he made, he doesn't like how big the space around him, he doesn't like the fact he's high on the second floor, he doesn't like that Derek is not here to comfort him, he—

There's a knock on the door, "Stiles, I'm bringing breakfast," Peter called.

—he doesn't like there are other wolves around him.

Stiles sniffles, "Go away."

"Stiles, don't be ridiculous," The door handle moves in vain, "Stiles? What's going on? Open the door."

Stiles buries his face into Derek's pillow and whimpers, "Go away! I'm trying to sleep!"

Peter sighs, "I'm calling Derek, Stiles. You know he'll worry."

I don't care, let him worry, Stiles thought grudgingly. It's his mate's fault to leave him alone anyway.

True to Peter's warning, few moments later, Derek's face pops up on Stiles' phone.

Stiles stares longingly at the gorgeous face before finally accepting the call.

"Hi," Stiles greeted shortly. He's pouting, not happy that his mate is away from him.

"Stiles, Babe," Derek said in a gentle loving tone, apparently immediately catching up on his mood, "Is everything okay?"

"I can't sleep," Stiles sniffled.

"Why? What's wrong?" Derek asked in worry.

"I miss you," Stiles admitted softly, hesitantly adding, "come home?"

"Soon, Sweetheart, I'm finishing up," The Alpha tried to sooth him, "Have you eaten?"

"'M not hungry..."

"Stiles, Baby please, you can't just skip meals like that."

"Derek," Stiles whimpered, "come home."

"Sshh alright, I'm leaving in ten, okay?"

Stiles weakly nods even though his mate can't see him.

"Tell you what, I'll get you that boba tea you like, if you finish a sandwich while waiting for me. How's that sound?"

Stiles takes time to consider before finally answer, "Strawberry?"

Derek chuckles, "Large boba strawberry milk tea comin' right up. Now, I'll ask Peter to bring you food, promise me you'll eat it? Stiles?"

"'Kay.."

"Good. I'll be home soon, My Love."

Not long after they hang up, Peter knocks on their bedroom's door again, bringing the food for him. Stiles receives it from the door, not letting Peter into the bedroom. Peter just raises his eyebrows at his unexplained solitude and leaves him alone.

Stiles truthfully loses his appetite, he just doesn't want to eat it, because it's not from Derek. But he promised his mate, so he forces himself to take a bite. Even so, he only manages to finish halfway before pushing the plate away.

After barely enough nourishment, Stiles lies miserably on the pile he made, waiting for his mate to come back. His discomfort gets the better of him. Tears start to fill sad honey brown eyes, as Stiles' emotion goes all over the place. He feels exposed and unsafe. His mind screams that he's not supposed to hide here.

Derek comes home finding the bedroom door is locked, it doesn't help to trample down his worry, "Stiles, it's me," he knocked softly on the door.

He heard rustling from inside and then the door unlocks, revealing tear-faced Stiles.

"Baby, c'mere," Derek goes inside and pulls the distressed pregnant mate into his arms, closing the door behind him, "Hey, tell me what's wrong."

Stiles sobs into his shoulder, "I don't- I don't know. I just don't wanna be here."

Derek feels lost, "Baby, what do you mean..? This is our home."

"I tried everything, but I'm still so uncomfortable, I can't sleep. And I want to sleep, Der.."

In confusion, Derek looks over his mate's shaking shoulder at the layers upon layers of covers and blankets on their bed, pillows scattered around. The room is dark because the all the curtains are down.

Realization hits Derek.

Stiles is nesting.

His pregnant mate is preparing to have their baby, as he can tell the day is close now. It's one of the most fundamental instincts a mother wolf has.

No wonder he's barely allowed to leave. His mate will rely on him to take care of him while he's nesting. Stiles will only eat what he offers; will only let him into the nest.

Derek's heart melts into a puddle; he's a lucky bastard to get to experience this in his life.

"Stiles, Sweetheart," Derek scoops his mate up, carrying him gently back to the bed, "Sshh, everything will be okay."

He joins Stiles under the layers, holding him tightly in his arms and pressing his lips on the human's temple, "Tell me what do you need, Baby?" There is nothing Derek wouldn't do for his sweet lovely mate.

"I just want to find somewhere else to rest," Stiles whimpered to Derek's neck.

Derek hushes him in a soothing tone. Stiles was clearly trying to nest here in their bedroom, and somehow the result doesn't satisfy his instincts.

"I know, Baby, tell me where you'd like to be, close to the ground?" Derek offered.

Stiles nods, "Warm, and dark, and no one's around," he tightens his grip on Derek, "except you. You have to be with me," Stiles demanded, no room for negotiation.

Derek cups his mate's cheek and kisses the whimpering pink lips, "I'll be with you all the way, I promise."

Derek is thinking about the options he has to offer, when he remembers a special place he shared with Stiles before.

"Hey, you remember our secret den in the woods?"

Stiles perks up in interest and nods enthusiastically.

Derek smiles, they have found the perfect solution. "Wanna come back there with me?"

Derek takes care of the logistics as fast as he can; he promises Stiles he'd be back in an hour max. He's grateful he brought the large boba tea as an offering that will distract Stiles for a while.

Before he leaves, he makes conference call to the pack and Stiles' father to update what's going on. The Sheriff comes to the Hale house right away to watch over Stiles until Derek's back. The pack is split up for errands immediately. Some get the things Derek lists, the rest sweep through and around the parameters to ensure the area is safe. Derek goes to clean up the cave and put the gathered items there.

And his pregnant mate needs a check-up first.

"Deaton," Derek greeted when the line connected, "It's Hale."

"Alpha Hale," Deaton greeted back, "How can I help you?"

"Stiles might be close to labor. I think it'll be in the next few days ahead."

"Should I make home visit?"

"Yes, please, and I need to update you that we have a complex situation."

"Oh?"

"Stiles is nesting, and huge possibility he wants to give birth in it."

"We can have the procedure at home, it's an option."

Derek clears his throat. "It's the situation, Stiles doesn't want to nest in our house. Somehow, he loves the idea of nesting in our den in the woods. It's a cave."

Deaton chuckles, "He surely doesn't do things halfway."

Derek privately smiles thinking about his waiting mate back home, "Can you make a home visit before we leave? Check if he's still in condition to give birth with normal procedure. And we need to arrange how he's gonna deliver the baby there."

"I'll be there in half an hour."

"Perfect, I'll see you then."

Derek ends the call and meets the pack near the den area. He briefs them that they will be on shift to patrol the territory as long as Stiles is out here to ensure safety. Protocol is in place if any threat occurs.

They will be able to feel it in the pack bond once the baby is born, and they can visit to welcome him. In the meantime, they can't enter the den area since it will stress the nesting mother.

Derek drops the rest of the items real quick; food, water, ice chest, mattresses, dozens of bedcovers, blankets, pillows, towels, and a few changes of clothes. It's the edge of winter and freezing cold out there. But it's less cold in the cave, and once Derek lights up all the candles he brought, it will be comfortably warm in here.

After the werewolf is satisfied with the den he's prepared, he runs back to his waiting mate.

Deaton is entering the driveway when Derek arrives. Both enter the house greeted by the worried Sheriff.

"He's locked himself in the bedroom again, said he wouldn't open the door until you got here."

Derek winces, checking his watch to see he only left for forty-five minutes. He gestures the other two men to follow him upstairs.

"Stiles, Sweetheart, I'm back," Derek softly called from behind the closed door.

Stiles opens the door and dives into his arms right away. Derek scoops him up and carries him to the bed, talking softly to his ear, "The cave is ready, we'll go after Deaton checks on the baby, okay?"

Derek joins him on the bed, letting Stiles sit on his lap. Deaton takes out his equipment and steps closer to the pregnant human, only to have Stiles shy away trying to hide himself in Derek's arms.

"No… Don't touch me," Stiles whimpered.

Derek hushes him, hands rubbing in soothing motion, "I'm here, I won't let anything happen to you or our baby."

Stiles looks up at him, complete trust shining from wide brown eyes, "promise?"

Derek kisses his forehead, "I promise. Quick check, then we go, okay?"

Stiles hides his face on Derek's shoulder, muffling softly, "'kay."

Receiving consent, Deaton proceeds the required check-ups, with Derek and the Sheriff asking related questions.

"Both mother and baby are in excellent condition. The birthing passage has developed completely. Newly found self-healing cells in the placenta and passage's wall. Slight swelling on the mammary gland, not as obvious in size as a female, but still a symptom that Stiles will indeed lactate. Safe to say, only with his Alpha's help, Stiles actually can deliver the baby on his own, heal himself afterwards, and self-sufficiently feed his infant."

Derek gulps, looking down at his sleepy mate in his arms, vulnerable and defenseless as ever. Nature's gift is great, but still, "Yeah, I don't think so. I'm not taking chances with their safety. Scott will take you to the den location when Stiles is in labor."

Deaton nods in understanding, "As you wish, Alpha Hale."

Derek wraps Stiles in a cocoon of thick blanket to protect him from the cold winter air, before carrying him bridal style on their short journey to their secret den. Allison, Scott, and Peter escort them, walking not far behind, rolling their eyes when the expecting parents start arguing over the silliest thing.

Stiles insists he can walk on his own, but the ground is slippery from thin snow so Derek won't let him. Fortunately, Stiles is too sleepy to stand his ground on the matter for too long, so in the end the human just lets his wolf carry him until they reach their destination.

The escorts stop just on the border of the lake in front of the hidden cave. Derek nods at them and the three pack members turn around and leave the premises.

Derek puts Stiles down on the mouth of the cave. Stiles takes a look around the den and smiles happily at the sight of stack of bedcovers, blankets, and pillows besides a dark corner made out of mattresses. He turns around and kisses Derek hard on the mouth, "mmm love you…" he murmured.

He then weakly attempt to push Derek out, silently asking Derek to wait outside as he intends to fix the nest the way he likes. Derek obliges without question, patiently waiting, not caring about the cold wind attacking him outside.

It takes a moment before he finally hears his name being summoned.

"Der…"

He makes his way into the den and his knees weaken at what greets him. It's a sight to be hold. Stiles lies in his giant inviting disheveled nest, as naked as the day he was born, baby bump protruding and offensively exposed to the world. Glassy honey brown eyes lock their gaze at him, grabby hands raised up wide open to him. Wanting him. Needing him. Demanding for him.

Only him.

Derek's breath is punched out of his lungs, words dying on his tongue.

He's never considered that something, someone, can be so precious.

He'd never thought that anything, anyone, could be so perfect.

How did he end up with this?

How could he be so lucky?

Stiles starts to whimper, pulling him out of his head.

He silently and quickly takes off his clothes, fingers trembling as he carefully lifts the covers and joins his mate in the nest, too scared to ruin this dream-like moment. Derek hastily fixes the covers over them; he has to make sure his pregnant mate is warm and comfortable.

What else does his mate need? Is he hungry? Is he thirsty? Is he cold?

Derek wants to ask but stops as Stiles sighs in content burying himself in Derek's arms, snuggling his face to Derek's neck unconsciously scenting him, clueless to Derek freaking out a little on the inside.

Moments later, the pregnant human is snoring softly. His huge baby bump is warm where every inch of it touches the skin of Derek's stomach. And then a soft kick can be felt skin to skin, reminding Derek of what's to come. Derek growls softly, eyes flashing red with raw possessiveness, sharp fangs yet gentle lips dropping tender kisses on pale freckled skin. Then his arms tighten around the vulnerable human, engulfing his sleeping mate and unborn son impossibly closer to him, every vein in his body burns with intense instinct.

Love. Protect. Love. Protect. Love. Protect.
