"I'll fuck you until you're too tired to even speak." 

This sentence really shouldn't have sent so many shivers down Stiles' spine. The thrill it brought him to hear it was incredible. The brunette couldn't help the excitement filling his body at the sound of these words alone. They were in the last few days of their trip and they had barely done anything but fuck. 

And yet, it was like neither of them could get enough. 

They could go on and on and they still weren't tired. Which should be the reason why Stiles had gotten so riled up at his mate's words. The idea that Derek would fuck him even better than he had been the past few days was rendering the human a complete mess. 

They had already gone a round or two and even though Stiles would be too sensitive already to go on much longer, it was like, in an instant, his entire body perked up at the words and went ready for what was to come. 

It really shocked the brunette. 

He didn't really understand what was wrong with him but it was as if something was pushing him to be closer to his mate. It had started the second day they had gotten here. And since then, all Stiles' been able to think clearly about was Derek, Derek and Derek. 

Something was off with him. 

It never happened before. 

It should make him panic. 

However, he had never felt so much at peace in his life. 

Because no matter how much his mind was telling him that something was going on with, there always was this tugging at his mind that everything was alright. There was some sort of warmth soothing his worries, making him believe that it wasn't something he should be alarmed about. And so, stupidly or not, Stiles decided to embrace this feeling and let go of his worries. 

Feeling Derek's hands roaming around his body as if it was the very first time doing so was always something that would get Stiles on edge. He liked the way the wolf treated him during sex. It was always rough and passionate before switching to slow and careful, and Stiles loved it. The contrast between the roughness and gentleness was exactly what the brunette always needed. 

And Derek was well aware of that. 

How? Simple. 

The wolf could read his mate like an open book. 

There wasn't anything that would be missed by Derek. He knew every single thing about the brunette's preferences during sex and he made good use of that knowledge everytime. There was just something about knowing every detail that never failed to get him hard. Derek had been so nervous when they had their first time, afraid he'd perform poorly for the brunette, that he wouldn't be able to satisfy him and reach Stiles' high expectation of him. 

Thankfully, that hadn't been the case. 

And it had been only thanks to his incredible ability to immediately tell Stiles' likes and dislikes during sex. His body language was just so crystal clear to the wolf that he never missed any detail. Every movement, every sound, every sigh. Every gasp, every grunt and moan. Every whimper, every heated gaze burning into his skin as he fucked him deeper, every curse word flowing out of his mouth. Every expression on his face, every sinful whisper of dirty words coming out of the brunette's mouth, every teasing smirk when satisfied and every tremor of his body as he reached orgasm. 

Derek knew it all. 

It had been engraved deep into his mind a long time ago, never to be forgotten.
