See the end of the work for more notes
The invitation made Derek nervous.  He knew Stiles and his father had a
notoriously close relationship—the younger boy constantly smelled of his
father.  The Sheriff’s mark was all over his son, but if that wasn’t enough,
the way Stiles acted whenever they got close just reinforced Derek’s sureness
that Stiles and the Sheriff had a relationship that went beyond what was
normally expected from a father and son.  It had been barely two weeks since
Derek made his intentions clear, kissing Stiles rough and possessively in a
dark alleyway, the metallic sting of blood in both their mouths after a brutal
fight with whatever creature in the long line of enemies they now had since
Scott had become the Beacon Hills Alpha.
When they pulled apart, Stiles laughed, although Derek failed to see what was
funny.
“Daddy’s not gonna like that.”  Was all he said back, but he crashed their lips
together again.
Now Derek was heading over to the Stilinski house with an out of the blue
invitation to dinner.  He stood at the door with his hand on the doorknob and
turned.  It was unlocked, but Derek didn’t enter.  It wasn’t out of nerves,
Derek was prepared for whatever was inside—or he thought he was, until the door
was barely cracked and a wave of arousal blew out of the door and washed over
him.  Someone in this house had been having a lot of sex, and there were only
two recognizable scents in the mix.
Stiles and the Sheriff.
Derek would’ve been lying if he said that the scent didn’t go straight to his
dick.  The truth was, he got off on the fact that Stiles always smelled like
his dad.  It was a werewolf thing, the desire to lay claim to the person you
wanted to bang, and it looked like the Sheriff was ready to put up a fight. 
Derek wasn’t one to back down from a challenge. He opened the door, shut it
behind him, and turned towards the living room.  The sight that greeted him
made him weak in the knees.
Stiles and his father were both on their knees on the carpet, The Sheriff
behind his son with one arm wrapped defensively around his waist and the other
hand gripping firmly to the sweat-dampened hair of his son.  Both were
completely naked, and the hefty scent combined with their position and lack of
clothes left no doubt in Derek’s mind that Stiles was stuffed full of his
father’s cock.
The scent of Stiles’ arousal was dizzying.  His normally expressive brown eyes
were half-shut and dazed, his face flushed a deep red that travelled down his
neck and over his chest.  He was clinging to the arm around his torso with both
of his own arms, and between his legs he was hard as marble and leaking onto
the carpet.  Derek’s eyes trained on the pink head of Stiles’ cock, hypnotized
by the thin trickle of precum that showed no signs of stopping.
“Hello, Derek.”  greeted the Sheriff, still rocking his cock slowly inside of
his son.  He moved his arm up Stiles’ body until it was around his chest,
forcing Stiles’ back straighter, allowing Stiles’ vision to take in Derek
standing in the doorway.  “Say hi to Derek, baby.”
Stiles’ head lolled on his father’s shoulder like he could barely hold it up
himself.  God, Stiles was wrecked, and a flash of rage went through Derek at
the realization that he wasn’t the man to do it to him.
“Huhhhder.”  Stiles slurred, his head dropping back forward with a moan. 
“Daaaddy…”
“As you can see,” The Sheriff continued, “Stiles is a little delirious.  He
gets that way from his daddy’s cock.”  He pulled Stiles’ head back up with his
palm over the boy’s forehead, nuzzling his nose against Stiles’ hot cheek. 
“Isn’t that right, Stiles?  You love to get fucked out on your Daddy’s cock
until you can’t even think.”
Stiles distant eyes locked with Derek’s when he moaned for his father again. 
“Daddy’s cock…”
“He doesn’t need anyone else but me, Derek.  Only I can break him down this
well.  You think you can come into his life and take him away from his Daddy? 
Stiles is mine.  And now I’m going to show you how mine he is.  Sit down.”
Derek obeyed the command like a reflex, the force in the Sheriff’s voice making
Derek feel like he had to sit, even if he wanted to stand, wanted to tear the
boy away from his father and prove the Sheriff wrong, prove that he could ruin
Stiles if he had the chance.
The Sheriff smirked and stood.  As soon as he released his grip on Stiles, the
boy slumped forward into the carpet like a puppet with his strings cut.  They’d
already been going for so long that he couldn’t keep himself up without the
Sheriff’s help.
“He’ll do anything for his Daddy.  And he’ll love every second.  It’s his
favorite thing to let me take him, claim him.”  The Sheriff moved Stiles across
the floor with a rough grip on his hair, and his boy fumbled to keep up,
flopping loosely back against the table, able to sit up now that his father had
propped him against it, but Stiles’ neck still refused to hold his head up so
it fell back against the table top.  “In a way, I have to thank you.  This
wasn’t his favorite part until he knew werewolves that could smell it on him.”
No sooner had the sentence ended than a stream of piss shot from the Sheriff’s
cock, cascading over Stiles face and soaking down his chest.  Stiles moaned
loudly and opened his mouth to catch some of the golden liquid on his tongue. 
The Sheriff redirected the stream to make sure he thoroughly bathed his son in
piss, pushing his head down and soaking Stiles’ hair, watching the wetness
cascade off his flat, wet brown hair and add to the mess on his body.
Stiles was harder than he’d been when Derek walked in, and had apparently found
the coherence to wrap his hand around his throbbing cock to jerk himself off as
he turned his face back into the stream, eyes closed tight and mouth opened
wide.
Derek palmed himself through his jeans in his seat.
Once the stream subsided, the Sheriff knelt in front of his son, grinning at
his work.  “Derek wants to do that to you too, baby.  But you’re Daddy’s,
aren’t you?”
“Daddy’s…”  Stiles repeated.  He seemed to shudder the word out of his mouth
and Derek realized that Stiles was cumming—rather, he was orgasming but had
long since been fucked dry, so he just writhed, over-sensitive and drenched in
sweat and piss and probably his own and his father’s loads.  But the Sheriff
wasn’t done yet.
“I can’t blame your taste at least, Derek.”  The Sheriff teased, repositioning
Stiles as he talked.  “He’s a good boy, and a perfect cockslut.  He keeps
himself ready for me with a plug.  Did he ever tell you that?  He likes his ass
nice and stretched open so I can just—”
Stiles ended up on his knees with his face pressed into the carpet and his ass
high in the air, making it easy for his father to sink back in to the hilt. 
“He’s so needy.”  The Sheriff began fucking Stiles so hard Derek was concerned
the boy’s face would end up with carpet burn, but Stiles just took it, loose
and moaning and utterly beautiful.  The Sheriff wasn’t even paying attention to
Stiles’ face, he had one hand in the boy’s soaked hair to keep his face pinned
to the floor as he fucked, but his own attention was completely on Derek.
“He was on my dick in less than five minutes after he got home the night you
kissed him.  I bet you didn’t think of that, that he would come right home to
Daddy and ride me until his knees went weak, telling me about the man who was
trying to take him away from me.  I trained him well, Derek.  You don’t get to
use him without my permission,” a mischievous glint flashed in the Sheriff’s
eyes, “Which you have until I stop fucking him.”
The Sheriff moved his hands back to Stiles’ hips and kept pounding, but what
the Sheriff was saying took a second for it to sink in for Derek.  Once it did
though, Derek was on his feet and naked so fast his clothes tore, putting his
hands in Stiles’ wet hair to pull his head back and get a good look at his
face.
Stiles mouth was parted slightly, his lips red and thick and wet and his eyes
still hooded lazily.
“I can vouch for the fact that his mouth is as good as his ass,” the Sheriff
said with a wink.  “Sometimes better.”
That was as much of an invitation as Derek needed.  Stiles moved however Derek
wanted him to, and it took no work at all to line Stiles’ mouth up with his
cock and shove the boy down, seating himself in Stiles’ throat.  It was warm,
and wet, and tight, but malleable and forgiving, taking Derek’s considerable
girth with no hesitation at all.  The intrusion had an effect on Stiles, his
eyes opening a little wider, his gaze slowly working its way up Derek’s body to
his face.
Derek held eye contact as he started to fuck Stiles’ mouth.  Pinned between his
dad jackhammering into his ass and Derek fucking faster and faster down his
throat, Stiles began to dry orgasm again, the vibrations of his fucked-out
moans only making Derek thrust more eagerly.  Soon enough he was keeping pace
with the Sheriff’s thrusts, pulling Stiles back and forth by his hair nearly
off his cock, then back on so hard Stiles’ nose ended up pressed into Derek’s
pubic hair.
Stiles began to move slightly like he was coming out of the trance his father’s
cock put him in.  It wasn’t much—his hands inched forward, gripping loosely
onto Derek’s knees—but the Sheriff saw, and he knew in that moment he wasn’t as
right as he thought he was.
Derek wanted to take it even further, so he moved from his knees to a seated
position, wrapping his legs around Stiles’ shoulders, shoving his head down
with both hands and keeping him down with his legs, choking Stiles on his
dick.  Stiles took it, but squirmed, the cock down his throat making it
impossible for him to get air.
The Sheriff and Derek looked at each other as they used the boy between them so
thoroughly, and something passed between them.  They leaned forward at the same
time and kissed violently, still pumping their cocks into both sides of Stiles
as their tongues wrestled and lips clashed, and with one last rough shove from
each of them they came in unison, filling Stiles up at both ends.
As Derek’s muscles relaxed he pulled Stiles off his cock—Stiles immediately
began coughing, trying to take in too much air too fast, but the color was
steadily returning to his face.  The Sheriff pulled out too, and Stiles was
laid out on the floor face down, unable to hold himself up at all.
“Hmm.  Maybe we can come to a deal.  But first, you need to see if he’ll let
you claim him.”  Using the same grip on Stiles’ hair from before, the Sheriff
yanked Stiles back to the table where he’d been showered with his father’s
piss.  “If he takes it all, I’ll make you an offer.”
Derek immediately moved over to Stiles and relaxed his bladder, but he’d
misunderstood the instructions.  Stiles, however, knew what the Sheriff wanted
to happen and dove forward before the first drop fell out, taking Derek
entirely in his mouth and drinking down Derek’s piss as fast as it poured from
his cock.  The Sheriff kept close watch, his eyes darting back and forth
between Stiles’ bobbing adam’s apple and his lips, to make sure he was
swallowing every drop.  Any spillage, and the deal was off.
Derek nearly collapsed when he finished and Stiles fell back against the table,
grinning as much as he could in his current state.  The Sheriff came up behind
him, placing a hand on the other man’s back.  “Well, that settles it.”  The
Sheriff said, “You can have him when I allow you to.  If I find out you ever
touch him without my permission, the deal is immediately off.  But for now… You
have until noon tomorrow to do whatever you want to him.  He’ll go home with
you now.  No point in letting him get redressed, so just carry him to your car
like this.  He’ll let you use him however you want, and so will I.  No
restrictions on what you do, but noon tomorrow, he’s back here.  Then we can
talk about more.”
Derek grinned.  There was a lot he could do between now and noon tomorrow.
