It was the fifth time, the fifth time Derek made him come. Derek like Derek Hale, Alpha in Beacon hills with a pack with teenagers Derek.

How they ended up here in his bed is a funny story, but right now it was really hard to concentrate mostly because all the heat and too much pleasure.

He could just moan and whine while Derek had his way with him, right now he was busy with kisses along the spine.

´Derek please... Pleaseaaah´ He had grind his hips against him causing stiles too moan and Derek groan. But then he stopped and all the warmth along his back was gone. He was about to turn when he felt teeth sinking down into his neck, hell it just made him more turned on. Then hands find his shoulder and he pulled stiles up. Then he arranged himself in a sitting position at the end of the bed. Then he led stiles right into his lap.

Stiles just became nervous, sitting in his lap where he could see his face. He was also a virgin until an hour or something ago so this was a new position.

Closing the eyes to not see Derek's face, he felt how he slowly moved his length inside stiles. He bit on his lip trying not to moan so loud, but it all fell apart when Derek find his prostate. He´s going with a rhythm groaning while so, then he begins to slow down.

´Open your eyes´ what? He just held his eyes still closed. ´Stiles open your eyes, please´ that was then he opened his eyes to the dark red. He blushed when a high pitched moan slipped from him again, Derek he just smirked at him.

´Don´t hold back´ he said while his teeth were showing in the smirking, fear for a moment went through him but stopped when Derek kissed him. Now the hips began to move and the thrusting began, his legs were shaking from the pleasure while Derek kept helping stiles up and down while moaning. He licked to the neck while leaving some marks, stiles was only his.

Shuddering and he came while Derek in him, Derek moaned loud while riding out. He was about to move out of Derek's lap mostly of embarrassment. But Derek held him still pupils big and round, that's when he felt something big down there. Oh no, No way! It can't be a knot… Right?

´ It isn´t a knot right, only dogs have knots right? Because I don´t know…´

´Stiles shut up and enjoy´ with that he kissed him heated while the knot moved inside, it hurt but still it was pleasure. Then he finally released and the knot could be moved out.

Stiles were sitting at his chair searching for answers, why? Scott was acting really weird and it scared him a little just a tiny bit.

Then a weird sound came from his window, he turned and saw nothing? What the hell?

He opened the window (He can be really stupid sometimes) and looked over. Then the Derek face showed up making stiles falling back while gripping his shirt. Before he could move he had a weight over himself. ´Hey Derek buddy! Mind getting of me?´

The answer was a growl and a tighter grip on his wrist. Now it began to be scary, maybe he had come to kill him?

´It´s happening´

´What´s happening? What´s going on´

´It's the mating season´

Then he kissed stiles with teeth's and all that. That explains Scott behavior, but now he couldn´t think of that…
