Dedicated to anon(omous). I hope you enjoy this! I've never read any fanfics with knotting, so I hope my improvisation is okay. Enjoy!

"Are you sure about this?" Derek questioned gently, hovering over Stiles' naked body.

"Yes..." Stiles sighed out readily, trying to remain relaxed.

"Okay... Tell me to stop or slow down if you feel uncomfortable."

Stiles nodded, looking into Derek's warm gaze, seeing the sincerity swimming in them.

Derek then slowly slid his erected member into Stiles.

Stiles whimpered as pain swelled in his stomach, breathing heavily.

Derek paused being only halfway in Stiles.

"Shhh baby... Breath. Relax." Derek soothed as he kissed Stiles tenderly to distract him from the pain.

Stiles unclenched from around Derek and seemed to relax slightly, as he delved his tongue into Derek's sweet-tasting mouth.

Derek then slid the rest of himself in Stiles.

"Agh..." Stiles gritted out as his nails dragged down Derek's back, as he adjusted to Derek's size.

"You okay?" Derek asked, stroking the pad of his thumb over Stiles flushed cheek.

Stiles nodded, signaling for Derek to start moving. Derek pulled out halfway then thrusted back inside Stiles.

"Fuck..." Stiles cursed.

Derek thrusted another time. Stiles appeared to be relaxing finally, pleasure taking over. Derek thrusted again and earned a strangled moan from Stiles.

"You okay?"Derek asked once more.

"Fuck me... please."Stiles begged, wanting to feel that pleasuring pain again.

Derek then began to buck his hips continuously. He leant down, burying his face in the crook of Stiles' neck as he nipped and suckled the exposed flesh.

"Agh... yes..." Stiles moaned as Derek groaned out in pleasure.

Derek's motions were quick and short, each time hitting Stiles' sweet spot. Every time Derek was rewarded with a sinful curse from Stiles.

"I'm gonna fill you up, baby..." Derek grunted as his hips rolled faster.

"Please..." Stiles begged, feeling Derek swell inside him,"Are we...?"

Derek's short thrusts slowed as he felt Stiles and him knotting.

"We're mating..." Derek smiled, feeling himself latch inside Stiles.

Stiles smiled back then kissed Derek lovingly.

"I guess this is a good excuse to stay in bed with you for half an hour." Derek joked, his voice sexy and raw.

"We're mates..." Stiles whispered joyfully, feeling Derek's seed filling him.

"What are we gonna name the little bugger?"
