5 weeks later… (Stiles)

I felt bad me and Derek had been dating for 5 weeks now and we got the go ahead to mate 3 weeks ago yet we haven't for one specific reason, me, the mating ritual means he has to take me raw and that he cannot wear a condom or we won't be mates!

The reason why I don't want to do it without a condom is because I will get pregnant! No jokes, I mean seriously I haven't even told Derek I can get pregnant yet!

I just wanted to dig myself a hole and die; when he finds out he won't accept me even if we are mates!

"Hey, Stiles I need to talk to you." While I was wallowing in self-pity Derek had snuck up behind me. I jumped from shock and he chuckled, it was hot!

Anything Derek did was hot! I mean the guy could be picking his nose and look hot! Fuck… what have I stuck myself with.

"Ah… sure what do you want to talk about?" shit I was worried as fuck! Please don't say he's going to break up with me because I won't have sex with him.

"Don't be so nervous, I'm not breaking up with you, never in a million years, okay I just want to talk about why we aren't mated yet? I mean we got consent to… or am I pressuring you, are you unsure because I know Valkyries can't just sense out their mate…" I looked at him and he was generally nervous, and I couldn't resist I had to tell him.

"Look we need to talk about something, I kind of didn't want to tell you, it's also the reason we haven't mated." He looked even more worried, who in their right minds would break up with Derek freaking Hale!

"You're not breaking up with me are you, because I will tie you down, I'm not joking right now, I will make you mine!"

His eyes flashed red for a second and I'm guessing he could smell the arousal on me, ever since I told him that I liked when he called me 'his' or 'mine' I collapsed in a sea of sexual need!

"Why on earth would someone break up with Derek sex-god Hale? And I don't know if you were trying to turn me on but come on, I'm semi hard!" this seemed to cheer him up, as he smirked at me.

"Then what do you need to talk to me about? What's stopping us from being together forever?" this time he was hugging me from behind with his chin on my shoulder and his arms wrapped loosely around my waist.

I smiled I loved it when he did this, "well you might want to sit down because it's really out there." We sat down on the sofa, him holding my hand, "You see I want to have children, do you want to have them as well and I don't mean adopted I mean my own flesh and blood."

He looked at me a bit astonished I could tell why, two men having a baby might seem a little weird but I wasn't exactly normal and neither was he, "Is that what it's about? I do want to have children, but I will do anything for you okay! Unless it puts you in danger!" he said with a stern voice.

I smiled. "So you want children then, if you could have them with me would you? And how far into the relationship would we have them, if we could."

He made a weird face then spoke "Stiles we can't have children so what's the point of talking about this, it's just going to make me angry that I can't follow on the Hale family by blood, okay." He was flustered.

"But if we could have them, please tell me!" I really wanted to know.

"Stiles if we could have children together I would want to have them as soon as possible and as many as we can because there ours and they wouldn't be anyone else's, hell if I could I would magically make you nine months pregnant with my children so I could have the life I want! You as my mate and then all our dozens of children running around!"

I smiled at him, I mean I want children but I don't think my body could take more than ten, it would ruin my figure but if that's what Derek wants I would gladly have a mangled body.

"Well there's something I didn't tell, I'm a rare species of Valkyrie there might only be three of my kind in the whole world." I made a big gesture with my hands and he looked at me confused…

"look I'm a type of Valkyrie called 'male birthers' as the name suggests we can give birth but that also means since when we mate you can't wear a condom there's a high chance of me getting pregnant."

He lit up; some could say he was the happiest alpha werewolf in the history of, well werewolf's. He picked me up and kissed me, "Let's take this to the bedroom shall we."

I smiled at him and then something popped in to my head "Also Valkyrie pregnancy's with humans are only three months long but with werewolf's it should only be two months." If it's possible his eyes shined brighter.

"That means I will have my pups in such a short time, I can't wait, but the only people I trust enough to hold them is me, Boyd and Isaac even you are on the so-so group." Well if that isn't offending.

"Derek I would have been holding them for two months already if you even dare say I can't hold them after that I will dream of killing you, but I have to admit you made the right chose not letting Scott or Erica have them, Erica might even get their little baby ears pierced!" the thought of having pups with Derek filled my mind, I was so excited!

Derek started to kiss my neck and that was my weak spot and I started to moan, he carried me upstairs and in to his bedroom, the whole house had been refurbished because he wanted me to live in it, he even got my dad's permission, but only after graduation.

I clung on to him, I had started to moan and every time there was a particular loud moan Derek would squeeze me tighter and grunt.

Damn his grunts were sexy; I would cum in my pants if I had to hear that all day and all night!

When we reached the bed Derek had already taken mine and his own shirt off, I had seen him with his shirt off before but shit up close it was fucking fantastic! He started taking off my sweat pants, I was wearing them because I stayed the night last night but just to cuddle, when he finally got them off I was breathing heavily and gasping for my breath his eyes glowed red for a second and then went back to his natural faded green colour.

I had gone with no under wear today because really I was just going to have a relaxing day until of course Derek and his hotness sauntered in.

I was about to reach for Derek's belt when he flipped me on my stomach and said in a gruff and lusty tone "Relax a bit or this will hurt." Then he pressed his middle finger in to me It didn't hurt as much as it felt uncomfortable to be realistic.

He started to move the finger in and out of me curling it at times and then with the same voice he had used before he said "This one will most definitely hurt so just try and stay relaxed and calm." And it did hurt one hell of a lot to be honest, though all I could do was moan and hiss at the feel of pain and pleasure hit me.

(Derek)

Stile's moaning was driving me to the brink of control quite literally, I knew my eyes were changing colour on and off and that my face features had grown a bit distorted not to my full werewolf face but my teeth had grown and my ears were a bit pointier, I just hoped my nails wouldn't turn sharp inside of stiles.

That's a catastrophe I would like to avoid, it will hurt even if he has done it before probably never get used to it, but that had got me thinking has Stiles had sex before? Just thinking Stiles has been with another man made me angry! I had to know. NOW!

"Stiles." I say with a deep voice almost threatening. "Have you ever had sex with another man before?" to be honest I didn't want him having sex with any females either but Stiles was sixteen and there is only so much one can with for.

Stiles were gasping for breath as he answered, probably wasn't the best time to ask when I had two fingers inside of him. "No… ah I've never been with anybody… nnh and before you even dare to ask… ha yes you are taking my virginity! Ah… ha nnh fuck more Derek!"

He asked for it, I plunged a third finger into Stiles and he moaned extremely loud I could tell it still hurt a little but he didn't seem to be minding anymore, and all of my wolf like nature was telling me to just drive in there and start pounding but I couldn't do that to Stiles it would hurt him and I made a promise to myself not to hurt him if I couldn't help it.

"ha Derek if you don't stick your massive ass dick in me right now I'm seriously going into your car and using the gear changer… mmh ha ah please! Derek!" that sent an image to Derek's head and combining the things he loved that belonged to him was really unfair! So he did as he was told.

When Derek entered despite all the stretching it was tight, extremely tight Stiles told him just to go all the way in so he could adjust quicker.

(Stiles)

He wouldn't lie it hurt he thought he was going to split open! Even though it hurt all he could think was that at the end of this Derek and he would be connected forever never to be separated and to add on to that he might be pregnant at the end of this and the thought of a mini Derek running around with Stiles clumsiness was the happiest things he had ever thought about.

But when Derek started thrusting into him he couldn't think couldn't generate proper sentences with his mouth and he couldn't stop moaning, it was quite embarrassing until he saw the look on Derek's face.

It was a face of absolute lust his eyes were glowing red, which turned Stiles on a lot, his teeth were out and Stiles thought about the time were Derek had come up behind him and nipped him on the back of his neck which then led its own way to Stiles having his first blow job.

He could feel Derek's nails start to grow into their werewolf form and dig in to his hips somehow it only turned him on more.

(Derek)

After a few more thrusts Stiles was moaning nonstop underneath Derek and Derek loved the sight and was oh so glad that he is the only one who will ever get to see this side of Stiles… "Derek… ha I'm going to cum! Ha DEREK! Ah love you…"

In that moment Stiles had tightened around Derek and after one thrust Derek had come inside of Stiles while biting his neck, drawing blood this bite wouldn't change Stiles it would though link him to Derek it would link their feelings so if one was feeling unhappy then the other would know.

The link is made straight away and Derek could feel Stiles' emotions and the only way to describe it was utter bliss, when the 'love you' Stiles had said hit his ears he could do nothing but smile and place a gentle kiss on Stiles' lips and answer with a possessive growl and a "I love you to, Stiles."

With that Derek pulled Stiles into his chest as he lay on his side and wrapped his arms neatly around stiles waist and Stiles cuddled into Derek's chest and wrapped his arms around his shoulders.

And Derek was happier than he was in a long time, that's when he remembered Stiles telling him he might get pregnant after, and another wave of happiness waved over him and Stiles next to him chuckled and said "I can't believe you're this happy, normally when men hear that they might have impregnated someone they get depressed."

I smiled. "Well I am not normal am I." we couldn't help but hold on to each other tighter.

(2 weeks later.)

When Derek woke up he felt extremely happy you would do to if you woke up and your mate was cuddled into your chest talking nonsense in his sleep, but then Derek realised something there were three heart beats coming from stiles.

He was overwhelmed with happiness his mate was pregnant with his cubs and they were to be born in just a few months but he wanted to make sure he wasn't hearing things so he woke up Stiles.

Shaking his shoulder lightly and whispering in his ear to get up, stiles stated to shuffle around in bed "two more hours." Derek chuckled at this, when normal people said five more minutes his mate always said hours.

"Wake up I'm taking you to Deaton, I can hear three heart beats coming from you."

At these Stiles was up like a lightning bolt he got dressed in the flash of an eye as well. "Hurry up sour wolf your taking too long!"

Derek chuckled one minute Stiles is half naked in bed the next he's out the door waiting in Derek's Camron, Derek got dressed and headed straight for Deaton, when he arrived the 'vets' were closed but he walked in anyway.

They heard Deaton shout "sorry were closed" and Derek just shouted back, sorry to come on short notice but do you think you can check if Stiles is pregnant. This obviously caught his attention.

"Derek, Stiles is a boy he can't get pregnant." And then Derek went about explaining Valkyries and male birthers and such other thing, while Deaton set up for checking Stiles stomach.

"Well done it seems Stiles is a week and a half pregnant with a Valkyrie timetable of course." After that they all had a long chat about how Stiles would give birth and Stiles went on to say that it was the same as women but it would have to be cut out through the stomach.

Derek didn't like this because it would leave scares on Stiles but then Stiles said that all birthing scares are erased when the child is exactly 1 day old, after that Stiles and Derek went back home being it was only 8am.

But when they got home Stiles did something and Derek just couldn't take his eyes off of him, he released his glorious wings.

They were a deep purple and the colour really seemed to suit Stiles, Derek then walked over and touched them, but then he remembered Stiles warning that he could die bit he didn't Stiles was staring at him with a massive grin on his face.

"It's because your my mate." His grin only seemed to widen and then Derek felt nothing but happiness and proudness, because he was going to be a dad! And only he could touch Stiles' wings.

But suddenly Stiles spoke up. "Other Valkyries can touch them to," this made Derek feel a bit sad but he was fine, though it didn't stop him from growling possessively and taking Stiles in a tight hug.

"Haha, that doesn't mean any have, it is seemed as a great offence to touch a Valkyries wings without permission unless you are related to them by blood, and I never let anyone touch my wings because I only wanted my mate to so don't worry about it."

At that Derek felt a lot better, he was the only person to see what Stiles looked like when he was turned on beyond compare and he is the only one to have touched Stiles wings. He was happy.

Hello my fellow Sterek shippers I just wanted to say I have another story on Sterek and if you would like to read it the name of the fan fiction is called 'Evolution'. If you would please review it would make me very happy.
