She left half an hour later giving Stiles enough time to slip some shoes on and grab his keys and overnight bag. His dad was doing the night shift any way so he won't know that Stiles was going to spend the night shacked up with a wolf. Like he was going to tell him 'Good morning dad how was your day at work… great by the way I am married to Derek by furry law, Great isn't it!' Yeah he could see that going down like a lead brick.

He left the house and headed up to Derek's loft. Derek was already waiting for him standing there with a smile on his face that made the teen melt, Stiles looked around the loft and saw that Derek spent his time making a nest in the middle of the living room, piles of blankets lay out and pillows with fairy light covering the whole place "Derek." Stiles whispered

"You hungry?"

"Yes." Derek grinned again as he scooped up his fox and carried him over to nest before claiming his lips making the teen moan in delight as he felt the soft plump lips of the wolf attack his lips before he pulled back "Nooooo come back!" Stiles whimpered

"Food first then sex and then food and then sex get the idea?" Stiles licked his lips and nodded as he Derek got up and walked over to the kitchen and pull up a take way bag and walked back over to him.

After they ate Derek started to strip Stiles off his clothes kissing every bit of skin he could find leaving little marks all over his body. Stiles moaned and shiver against the wolf as his large hand rubbed all over his skin moving down his sides to his hips pulling his jeans off him. The teen was growling as he looked up at Derek who flashed his blue eyes as Stiles eyes flashed red as he warped his arms around Derek's neck and kissed him on the lips as he felt the wolf's fingers move to his entrance and pushed two fingers into him. Stiles winced a little as he felt the two fingers work into him "Ummm you're all wet for me." Derek purred into his neck as he pushed his fingers deeper into him

"D…Derek." He whimpered he felt Derek left Stiles leg up making his fingers push in deeper

"P…Please I need you." Stiles groaned as another finger was pushed alongside the other two fingers, Stiles cried out as he felt the fingers wiggle against his sweet spot

"Got to make sure you're nice and open for me."

"Derek please I need you I feel like I'm burning up!" Stiles cried out feeling the wiggling fingers drive him insane."

After a 5 more minutes of Stiles babbling about Derek's fingers, Derek pulled his fingers free and pushed Stiles down to the soft pillows before turning Stiles onto his stomach and pulling him to his knees. Derek covered his cock in the thick fluid that was leaking down Stiles thighs. "Derek!" Siles whimpered as he felt the blunt end of the wolf's member sliding into him getting a scream out of the fox under him. Stiles arched his back as he felt Derek start to rock his hips into the teen moving at his own pace for him and the fox. The teen moaned and cried out as he felt Derek's snap his hips into his body over and over again.

It didn't take long for both of them to change into their wolf and fox and carry on with their mating, Derek growled and lowered his head sinking his teeth into the back of Stiles neck. Stiles screamed as he felt the teeth go into his skin but it wasn't a scream of pain just pleasure because that is all he could feel was pleasure and the growing knot started bloom. He was trapped between Derek and the pillows and was loving every moment of it especially as those bundle of nerves was battered by Derek's member.

With one push Derek's knot was buried deep into Stiles body tying the two together, it just added to the building pleasure in Stiles and he came with a cry as Derek started to fill him with his seed. The teen growled and whined as he felt the heat flood his body. Stiles twitched as he felt Derek pull his teeth out of his neck and licked the wounded making Stiles groan as the wolf pulled them onto their side. Stiles slightly winced as he realised he was lying in a poll of his own cum that was now sticking to his thigh "You okay?" Derek whispered as he rubbed his hand over Stiles slightly plump stomach

"Yeah." Teen whispered feeling his throat was sore "My neck hurts." He told him

"Ummm don't worry it will heal." Derek purred into his neck.

This carried on for the rest of the night, sex and then having something to eat and drink and then more sex, and before Stiles even knew what was happening 3 nights have passed and his dad was ringing his phone wondering where he was. But because he never answered his called the Sheriff found them in the morning after the last full moon.

Stiles was coming out the shower and put on some clean clothes when he heard his dad yell at Derek, the teen winced as he creped down the stairs and looked to see his dad standing there holding a gun in his hand by his side "Dad!" Stiles yelled as he rushed over to them, John turned to look at Stiles and frowned when he saw some bruise on the side of his son's neck and turned back to look at Derek

"What did you do?" He growled at the teen

"I mated with your son." Derek said calmly, while Stiles moved and slipped between them

"For three days you being buggering my son!"

"Dad please, Derek is my mate. I wanted to do this for our pack." Stiles told him as he tried to take the gun out of the Sheriff hands

"Scott's pack?" John asked with a frown, Stiles shook his head and then flashed red eyes up at his dad

"No my pack, I am as of three nights ago the Alpha of the Hale pack and Derek is my mate." John looked confused, sighing the teen rubbed the back of his neck "McCall kicked me out of the back because I am a Dark Fox and…and before you freak out and give yourself a heart attack it's not like before." John blinked at him as he let his son take his gun.

"Scott kicked you out? When? Why haven't you or Scott told me or Mellissa? And why him he's 27 years old?" Stiles turned to Derek and smiled

"Your 27?" He asked, Derek drugged

"In human years." Derek smirked, as Stiles turned his head to his dad and smiled at him.
