Summary
     Derek knots Stiles for the first time.
Derek finds his mate in Stiles and it’s different than he ever thought it would
be. Stiles is perfect in every way, he soothes his wolf and calms him, anchors
him. Stiles is beautiful and sarcastic and witty and funny. He thought that
Paige was his mate at first, but his senses had been off, it was a silly crush,
not one sided, they’d kissed several times and he’d went on several dates with
her, but it never went anywhere. He’s still friends with her. He’s thankful for
that. Paige is a very nice girl. But Stiles is—Stiles is his everything. 
They’ve had sex tons of times before, been together for over a year, but the
first time he knots Stiles he doesn’t expect it, and neither does Stiles, but
Stiles just urges him on, both of them sweating, panting and Stiles is
scrambling to grab onto Derek’s shoulders, moaning into his skin and cursing
out obscenities into his ear of “Fuck yes, right there, oh god!” and "Your knot
feels so good, mm." 
Derek just holds him through it, since he can’t really move and his father had
told him briefly when they discussed knotting and sexual maturity for
werewolves, that it could take a half an hour to an hour and Derek almost
winces. He doesn’t hate the idea of being tied to Stiles for so long, but he
doesn’t want to hurt him either. Thank god he took his time preparing Stiles.
He didn’t count on knotting him, but he’s so happy, so unbelievably happy. 
Derek noses against Stiles’ neck, breathing in their combined smells, the smell
of sex and sweat and come. Derek licks a wet stripe up the column of Stiles’
neck, tasting Stiles’ sweat, he whispers, “Mine,” against pale mole dotted
skin, nosing there as he moves forward a little, his knot brushing against
Stiles’ prostate. 
"Fuck, Derek." Stiles pants, tears gathering in the corners of his eyes.
Stiles’ hands tangle through Derek’s damp hair as he leans forward and pecks
Derek on the lips. 
Both of them lay entwined together for another half an hour, pressing open-
mouthed kisses on each other’s lips as they wait for Derek’s knot to go down.
By the time Derek thinks his knot has gone down enough for him to pull out, he
just rearranges Stiles and him so they’re both laying side by side in front of
each other. 
Derek pulls Stiles flush against him, kisses Stiles’ forehead, mutters, “I love
you.” 
Stiles huffs quietly, running his fingers down Derek’s bare thigh, “I love you,
too.” 
They fall asleep like that. In each other other’s arms, content and happy.
