Work Text:
Derek was working on his latest project. He had run out of black pens in a record time. Luckily Stiles anticipated that. A new set of them seemed to just appear on Derek's desk when his last pen runs dry. Stiles knew how focused Derek gets when he’s nearing a deadline. Derek appreciated it.
When the project was done and send off to the clients company, Derek got from behind his desk, staggered to Stiles’ and his bedroom. He let himself fall face first, into the bed. Stiles had gone to bed hours before and just gave a little grunt to acknowledge that he had heard and had felt Derek hit the bed. A grunt in return was made by Derek, both of them were asleep in a second.
In the morning, Derek rolled his face in his pillow that smelled of StilesandDerek, doing so he felt the black pen, he had left behind his ear. Derek grabbed the pen, brings the end of it to his lips and pondered.
He had a found a pastime in stargazing during the night leading up to the full moon. But no star or constellation was prettier than those that grace Stiles’ skin, he thought as he watched Stiles naked back softly rising and falling with each breath. The blanket had draped itself over Stiles’ hips. Derek wanted to run his finger along the line of the spine. He changed his mind as he moved the pen around in his hand. After a bit of shuffling Derek sat upright, he’s movement had shook Stiles out of his sleep.
"Good morning.", Stiles croaked.
"Hey," Derek replied, "Do you mind if I do something?"
Stiles grinned, “Nope, big guy, go ahead.” Derek smiled at Stiles, as happiness swelled in his chest for seeing yet again the trust Stiles has in Derek. Stiles smiled into his pillow and closed his eyes, relaxed and waited. Derek twirls the pen one more time and removes the cap.
Stiles stirs again, looks over his shoulder at Derek and raises his eyebrows “What …”
"I might want to try and see if I can recognize any constellations in your moles." Derek interrupts.
"Oh", Stiles said softly, "hmm okay." Stiles laid back down, shuffled a bit and exhales when he found a good position.
Derek sets his pen down to Stiles skin and starts to connect the moles. Near the top of Stiles’ left shoulder, he sees the Ursa Minor. Derek tilted his head and saw Crux in the moles below Stiles’ left shoulder blade. Derek was looking with wrapped attention at Stiles back as Stiles enjoyed the soft tiny stroking feeling caused by tip pen running over his skin. Derek went on and added two more constellations on Stiles’ back, one on his right shoulder blade and one in the center of his back.
After bringing the cap back on the pen, Derek kissed the top of Stiles head, and murmured “You starlit my heart, so it is not as dark as it was before”.
Stiles mumbled reply was, “You sap, come here.” Stiles rolled on his back and pulled Derek in for a kiss.
