"Stiles, I don't understand why we have to see Deaton, I think a general doctor is more appropriate to check your wound." Derek asked as he maneuvers his camaro on its way to the animal clinic.

Stiles just curls his hands on his little 'bump' protectively, he doesn't know what to say to Derek. He recognizes the symptoms, but what if he's wrong? And more importantly, what if he's right? Stiles hopes he's right, in fact Stiles will be heartbroken if he's wrong, but what about Derek? What if Derek doesn't want this? Stiles could die from the heartache, even thinking about the possibility makes Stiles sick in the stomach. And apparently, his mate notices his distress.

"Stiles, what's wrong? Your stomach hurts..?"

One of Derek's hands moves from the steers to Stiles' stomach and rubs it soothingly, like he wants to take the pain away with it. Stiles feels heat creeping to his face, because the gesture feels so intimate. If Stiles is right, Derek is now rubbing right where their...

'No, Stiles, don't get your hopes up yet. Let the expert check on it first.'

Stiles shakes his thought away and clears his throat.

"No, I'm fine." Stiles gulps, "I just—I trust Deaton more to check on my physique, that's all."

Stiles smiles at his mate, but from Derek's concerned face, he knows his mate is not buying it. Stiles can't explain anything further, he's freaking out himself too.

"Can't you just please hurry, Derek.." He pleaded.

Derek moves his hand from Stiles' stomach to cup Stiles' cheek, caressing it softly.

"Hang on, Baby, we're almost there."

'And of course he chose THIS moment to use THAT nickname for the first time.'

Stiles mentally groans. Derek always knows how to make him die internally.

Stiles sits on the examination table as Deaton washes his hand on preparation.

"You came here just to check that small scar on your head?" Deaton asked.

Stiles squirms nervously on the table, he doesn't know where to begin. Deaton turns his gaze to Derek who's standing few feet from the examination table with his hands crossed on his chest, eyes never leaving Stiles.

"And you dropped him here yourself? He must be your favorite in the pack."

Derek just spares Deaton a glimpse before focuses his eyes back on his mate.

"Stiles is my mate." He said like it's the simplest fact in the world.

Deaton goes 'ah' like it is a simple little fact and starts his examination of Stiles.

"So, Stiles, can you tilt your head up to the light while I open the patch?" Deaton's waiting.

"Uh.. Actually, that's not why I came here." Stiles started.

"It's not?" Derek was the one who responsed, his eyebrows frown with worry. "Stiles..?"

Stiles shoots a little smile at his mate."It's ok, Derek, I just need to check on something."

Stiles turns to Deaton. "Well, I have these symptoms. And-uh.. I know where these symptoms lead to.. But the thing is, I didn't know this could happen to...me, I mean, even if it could, I never heard about this case before. So, I need you to do, I don't know, a test or something.. On me. Or whatever. I don't know the procedure of this stuff."

Deaton hums. "Ok. Can you tell me what symptoms that you were talking about? And details, please. Just tell me everything, don't leave anything behind." Deaton said.

Stiles nods in understanding. He takes a deep breath and start explaining. "Well, first of all, I get so emotional over everything, actually I feel like I'm turning into some troubled chick on a bad tv drama. And I'm hungry all the time, I even ate six cheeseburgers at dinner once. Not to mention that I'm also as horny as rabbits in mating season, no this is serious, I'm not trying to be funny here." Stiles explained when everyone in the room look at him like he grows second head. "These have happened for two months! Then, nearly a month ago, I started having morning sickness, vomiting and stuff. And few days ago, I found out that I—uh—I gained fourteen pounds. So I checked myself out in the mirror.. And I..noticed that there's a bump in my belly. I just want to know if it's fat...or something else."

Stiles looks at Deaton meaningly, while Deaton's face turns serious and thinking hard.

"Stiles, please take off your shirt and lie down." The veterinarian demanded.

Stiles does what he was asked to. Deaton wears the stethoscope on his ears and touches few spots on Stiles' 'bump' with it, listening carefully. After a few moment, Deaton looks awed.

"It does exist.. I thought it's just a myth.." He whispers to himself.

Derek tenses. "What? Deaton, tell me. What happened to Stiles? Is he okay!?"

Deaton looks over his shoulder to Derek, "does Stiles smell different to you lately, Derek?"

Derek looks confused. "Actually, yes. Why?"

"Is it comforting or disturbing?"

"What?"

"Derek, is it comforting or disturbing?" Deaton pressed.

Derek frowns. "Comforting, actually. Dammit Deaton, what the hell are you implying exactly?"

Deaton is not answering, he keeps listening to Stiles' belly with his stethoscope. Meanwhile, Stiles is getting more nervous from watching Deaton's reaction.

"Deaton, do I need to have some test or something?"

Deaton shakes his head once.

"Not necessary."

Stiles can't breathe from hearing the vet's answer. It seems like all his hope is shattered into dust, he feels tears pricking in his eyes. "T-This is j-just a big bunch fat..?" Stiles' voice breaks.

Suddenly Derek is next to the examination table, taking Stiles' hand and brushing Stiles' hair soothingly, obviously sensing that his mate is upset.

"Deaton." He growled in warning.

Deaton finally puts away his stethoscope from Stiles' belly and pays attention to the pair in front of him.

"No, Stiles. We don't need any test to get the answer that I believe what you're looking for. I already hear it from my stethoscope, Stiles." Deaton said calmly.

Stiles doesn't get what Deaton's trying to say. "What do you mean? What did you hear?"

"A heartbeat, Stiles. There's a sound of faint heartbeat inside your stomach." Deaton explained, he then looks at Derek's gobsmacked face and smiles merrily.

"Congratulation, Alpha Hale, you're having a pup!"

Stiles' heart bursts in happiness. Tears are leaking from his eyes as he grins brightly from the news. Oh fuck, he's having an emotional breakdown again. But it's ok, it's from the pregnancy, Stiles will accept anything willingly. He's carrying Derek's baby. Derek, the man he loves. He looks at his mate, wanting to see his reaction. Derek freezes in his spot, staring blankly at Deaton.

"Derek..?" Stiles whispered his mate's name with a shaky voice, he's scared of Derek's expression.

Derek doesn't react to Stiles' call. He keeps staring at Deaton. "What.. What did you say, Deaton?" He finally responded. "Is this some kind of joke?"

Stiles gapes in shock. His heart is clenched and shattered into million pieces, it feels like his world is crashing down on him. Derek is not happy. His mate doesn't want this.

'Derek doesn't want my… no,our baby..'

Tears of Stiles' broken heart leak out of the corner of his eyes. Meanwhile, Derek is still focusing on Deaton, trying to grasp the idea of his male mate being pregnant. Deaton calmly try to explain the situation to the Alpha.

"No, Derek, I believe Stiles is about three months pregnant, according to when the symptoms started. But I'll do some examination to check the pregnancy state."

Derek gapes in disbelief. "But I didn't hear the heartbeat before! How could I miss it?"

"It is not in your hearing range yet, Alpha Hale, well not for another few weeks."

"But—but how is this even possible!?" Derek pushed.

"I also thought it was just a myth before. There's an old book stating it happened to a male Alpha's mate in a small village in France two hundred years ago, but I never heard this case happen in my lifetime, so I thought it was a lie. Derek, what happened to your mate is a miracle."

Derek shakes his head in awe. He looks at Stiles, then he realizes his mate is crying silently.

"Stiles?" Derek straightly focuses on his mate, Deaton's existence forgotten.

Deaton clears his throat awkwardly, "I'm going to prepare for the examination." With that, Deaton's heading out of the room, giving the pair some privacy.

Meanwhile, Derek is cupping Stiles' cheeks, brushing the tears away.
"Stiles, tell me what's wrong? Are you hurt somewhere?" Derek said in a panic tone.

But Stiles just keeps crying. "D-Derek, you don't want this b-baby..?" He asked with a shaky whisper.

Derek looks taken back. "What?" He frowns. "Stiles, how could you—Stiles, is that why you're crying?"

Great, now Derek thinks he's lame. Stiles closes his eyes in shame and looks away from his mate, tears still wetting his face. Suddenly he feels his body being lifted and crushed in a strong embrace.

"Fuck, Stiles, where is this coming from..?" Derek tightens his arms around his crying mate. Stiles buries himself in the embrace, his hands grip the back of Derek's shirt desperately.

"You s-said it was a j-joke.." Stiles hiccuped.

"What..? Stiles, no, you misunderstood me. I just—I'm shocked, Stiles, who wouldn't be?"

Derek tries to explain, but Stiles doesn't know why he can't stop himself from crying. He was so scared that Derek was denying him and the baby.

"Der, I-I don't know w-what to do.. If you don't want—" Stiles tried to speak between his sob.

"Ssshh.. God, Baby, I'm sorry, I didn't mean to sound like I wasn't happy about this, I am.." Derek runs his hand through Stiles' hair, rubbing his scalp soothingly.

Stiles pulls away a little bit and looks at his mate with his teary big brown eyes, hints of hope in them. "Y-You want the b-baby..?"

Derek smiles sun-blindingly at his mate, then leans in and drops kisses on Stiles' wet face as he whispers, "of course I want the baby, Stiles, I love you.." Derek pecks Stiles lips, "and I'm sure I will love our baby." He whispered and kissed his mate again passionately.

Stiles releases a relief breath into the kiss. Derek breaks the kiss and wipes Stiles' cheeks with his thumb.

"Now stop crying, you look terrible." He smiles teasingly.

Stiles hits his mate's arm and pouts, while trying to calm himself down. Derek laughs softly and pulls Stiles in his embrace once again.

"I got you, Snowball, I got you." The werewolf whispered.

Few hours later, Stiles sits on a chair in Deaton's office. Derek sits next to him, dragging his chair very close to Stiles' so he can curls his arm possessively around Stiles' shoulder. Stiles blushes to have his mate develop some PDA in front of the vet. But he enjoys the comfort, so what's there to complain about?

Deaton had done some examination, and now they will hear the result.

"Stiles, the fetus is indeed three months old. The condition of the baby is healthy. There is no complication or abnormality indicated."

Stiles and Derek breathe in relief. Deaton continues, "but your blood pressure is lower than I'm comfortable with, you have to take good care of yourself, Stiles. You're a human, yet from the milestones of the development, I believe your baby is a werewolf. Your energy will be drained quite a bit, and the baby will grow very fast. You probably won't feel a hundred percent for the rest of the pregnancy. Eat and sleep well, and do not push yourself in heavy activities. It's for the health of the baby too. You can make sure your mate is not under any stress, Alpha Hale?"

Stiles feels the arm around him tightened.

"I will." Derek growled lowly.

'Oh God, don't tell me that I will have a very protective grumpy werewolf in my personal space for months ahead..'

"Good, and can you come back tomorrow to do the Sonogram? Also, I ordered the prescription to reduce your pain due to the baby's growing spurt, it should be arrived tomorrow."

"We will be here. And about the pain.. Will it be bearable to him?" Derek asked seriously.

"I have to be honest to say that it will be a disturbing pain, but not life threatening." Deaton answered.

Stiles shrugs. "No big deal, I just have to take it easy for the next six months, right?"

Derek gives him a look.

"What?" Stiles asked obliviously.

Deaton answers for the Alpha, "Stiles, you're carrying a werewolf. You will give birth in two and half month."

"You say WHAT!?" Stiles sits up straight abruptly.

"Stiles, calm down. Remember the baby." Derek reminded him.

Oh, yes. Baby. Stiles lays back down on the chair.

Deaton nods once. "Yes, werewolves carry their pups for five and a half months. You are a human, but since what you carry is a baby werewolf, the stopwatch works for you too. You are two and a half months away from labor."

"Oh my God!" Stiles said excitedly. "I'm gonna be a dad two weeks after I graduate!"

"Yes, Stiles, congratulation to both of you." Deaton smiled at the Alpha pair.

"Oh my God! This is fucking awesome!" Stiles exclaimed.

Derek sighs in amusement toward his mate's antics. "Stiles, don't swear in front of our unborn child."

It's already dark when the camaro reaches the Stilinski's property. The Sheriff's patrol car is not in the driveway, his dad must be working late again. Stiles unlocks the front door and gets into the house, Derek follows right behind him. Stiles makes his way to go upstairs, but suddenly he's being swooped up.

"D-Derek?" Stiles gasped in surprise.

"The doctor said to take it easy." Derek reasoned simply as he steps up the stairs, carrying his mate in his arms.

Stiles scoffs exasperatedly. "Derek, stairs are easy."

"Not taking any risk." Derek said simply.

Stiles rolls his eyes, but let Derek carry him upstairs anyway.

"Ok, we're here, you can put me down now." Stiles said when they reach second floor. But Derek keeps walking toward Stiles' bedroom. He opens the door with his elbow and pushes it open with his leg.

"Derek, seriously!?" Stiles frustratedly whined.

Derek puts Stiles down gently on the bed, and then help him take off his shoes, and starts helping Stiles out of his clothes.

"Der—No, Derek, stop!" Stiles whines and bats Derek's hands. "I'm carrying a baby, Derek, I am not the baby." He glares at his mate.

Derek huffs and hugs his mate, pushing down Stiles with his weight onto the bed.

"Oof!" Stiles flops down on his back. He is blanketed by Derek's warm body as Derek hides his face in the curve of Stiles' neck.

"You're pregnant and I didn't even notice.. I let you wander around by yourself, play sports and join pack training, and just this evening you passed out and hurt your head.."

"Derek.." Stiles whispered, but Derek just tightens his embrace and keeps talking.

"I keep promising your father that I will take care of you, that I will protect you, but look how shitty a job I did.."

Stiles hugs his mate back. "Derek, don't say stuff like that.."

Derek makes a small whimper, it shocks the hell out of Stiles to hear the big bad wolf make a sound like that.

"What if you didn't recognize the symptoms and we didn't go to Deaton.. You could have been hurt.. And we could've lost our pup and I didn't even know what's going on.. Fuck. I screwed up big time." Derek whispered to his mate's neck.

Stiles puts his hands on each side of Derek's head and turns it to face him. Derek looks hurt and drowning in guilt.

"Hey.. Hey, Derek, listen to me. I'm fine. The pup's fine. I don't want you to blame yourself, you didn't know Derek, you-didn't-know. Deaton said it himself, it's not a common case. Ok..?"

Derek huffs a breath and nods once. Stiles smiles and caresses his mate's stubbly jaw lovingly.

"Ok. Now c'mon, show me that happy face. Don't frown like that, our kid can copy the behavior." Stiles smiles brighter when he sees the lips of his mate twitch.

"The baby's not even born yet." Derek said, starting to show amusement.

"He can still see you through my eyes." Stiles argued without so much thinking.

Derek now smiles teasingly, "oh really? We can't have sex then. We definitely don't want to scar the kid for life."

Stiles gapes at the idea that his mate brought up. "Woah, woah, woah! Time out! Nobody said anything about no sex, this momma has needs!" Stiles said too eagerly.

Derek raises his eyebrows, lips grinning in amusement, all worries forgotten in the moment.

"Stiles, did you just call yourself momma?"

"Uh—Yes, so? And this is the part where you should have said 'tell me who's your daddy'."

"Nope. Not happening."

"Aww you're no fun.."

Derek grins playfully, leaning in closer to Stiles' face. "I'll show you some fun."

"Ooo.. Is that a suggestion?" Stiles giggles as he flirts with his mate. He catches Derek's lingering lips with his and curls his arms around Derek's shoulder. Derek grins and kisses back his adorable mate.

"Stiles.. My mate.. My love.. My everything.."

Derek's purr vibrates through Stiles' body, waking up all of Stiles' desire for his mate. Stiles moans softly.

"Derek.. My wolf.. Show me how much you love me.."

And the next thing Stiles knows, he is drowning in Derek's love as his mate handles him, full of passion and gentleness, like Stiles is the most precious thing Derek has ever possesed and he's afraid he'll break him. Derek's adoration and love wash over Stiles like an oasis in the desert.

"My mate is pregnant.." Derek whispered in awe. His hand moves to carress Stiles' belly gently.

"My pup.." He purred. Stiles' heart bursts in happiness, his instinct is set on fire by his mate's worshipping attention.

"I love you.." Derek whispered to Stiles' ear.

"I love you too.." Stiles whispered back, eyes tearing up.

"My sunshine.." Derek called him.

"Oh, Derek.." Stiles cries, touched by his mate's love.

"Don't ever leave me.." Derek begged him.

"Never.." Stiles gasped his promise as Derek thrusts into his waiting body. He kisses his mate with everything he has.

The two lovers bare it all, their feelings are overflowing in the air as they make love passionately deep into the night, expressing their happiness and excitement for the new life that sleeps inside Stiles' body.

Stiles can't wait until the baby is born, this pup will be so loved.
