****** What Derek Comes Home To ******
by ticklemekink
Summary
     Derek comes home from a long day at work, ready to spend the evening
     on his favorite pastime.
Notes
     Warning: Contains beastiality, with an actual animal, not Derek in
     wolf form. Sorry if this isn't your kink. If it isn't, I don't
     recommend reading. Stiles is probably like 16 or 17 in this fic. My
     head canon is that he was orphaned and taken in by Derek, who became
     his daddy while also his boyfriend.
     If people like this, I'll consider making it a series. This is the
     first time I've written porn, so please be gentle heh.
     Tell me what you think!
     I need to know whether it sucks or not so I know whether I should
     bother trying to keep writing porn.
See the end of the work for more notes
Derek dropped his bag as he walked in the door, tired after a long day at work
and definitely ready for a little of his favorite form of downtime. He could
already hear pleased whines coming from the other room, making him grin
wolfishly. He decided to take his time getting around to joining. He’d let Milo
have his fun.
Whistling lightly, Derek undid his tie as he stepped through the foyer and into
the living room. He cast a cursory glance at the sight before him, but after
that pretended to ignore it and kept a straight face. Considering the scent of
arousal that permeated the entire house and made Derek’s fangs want to drop, it
was extremely difficult to pretend he didn’t notice.
Walking into the kitchen, Derek proceeded to get out a few things for dinner
later. At this point, he was simply stalling, letting the noises drifting in
from the living room cause his cock to slowly harden as he whistled and
puttered around. Finally, after being home for fifteen minutes, he walked back
to the living room and acknowledged what was happening.
“My my, what a lovely thing to come home to.” Derek nonchalantly leaned on the
door frame separating the two rooms as he watched.
In front of him, on the floor in the middle of the living room, Stiles was on
his hands and knees. Their dog Milo, a rather large Utonagan, was mounted on
top of him, furiously thrusting his thick cock into Derek’s mate. The tiny
skirt Stiles was wearing was pushed up to his waist, his little lacey panties
were around his ankles, and Derek could see his puffy little tits through the
thin camisole he was wearing.
Stiles looked up at Derek as he finally spoke, his eyes glazed over and his
mouth slightly open; he looked desperately aroused. Before he’d left for work
that day, Derek had told him that he was allowed to play with Milo, but he
wasn’t allowed to play with his little clit at all. Stiles had probably been
dying to come for hours and the thought made his cock as hard as a diamond,
forming a visible outline in his slacks.
“Derek…” Stiles whined as Milo jostled him with his hard thrusts. He stared at
Derek’s crotch and licked his pink, bitten lips.
Derek frowned. “Now now, is that any way for a good little girl to greet me?
No, it’s not.”
Stiles bit his bottom lip. “Sorry, daddy! I’m sorry.” Derek swooped in before
he could get any more upset, sitting down next to him and making soft cooing
noises, hushing him.
“It’s okay, sweetheart. I know you’re daddy’s little girl. Daddy’s gorgeous
little girl. Have you been giving Milo everything he wants today like a good
bitch? Did you let him fuck you whenever he wanted, let him ruin your slutty
little pussy with his thick doggy cock? You know how proud I am of you when you
do.” Derek ran a hand up and down his mate’s back as he spoke, soothing him. He
looked at Milo as he fucked Stiles; his tongue was hanging out making him look
like he was grinning. And Derek could hardly blame him.
“Ye-Yes Daddy. Everything he wa-wants. Four ti-times today,” Stiles stuttered
out between thrusts. Derek hmm’d.
“Four times? Damn, you must have driven your stud crazy, slutting around in
your little skirt, flashing your panties at him, showing off your tight little
pussy.
“And you didn’t touch your clit, did you?”
“No, no daddy! You told me not to.” Derek smiled. He believed it too; Stiles
cock hung between his legs, drooling all over the floor, and damn did it look
flushed.
“Good girl. But now daddy’s home and you know how much I love your little
clitty.” He reached down and began to stroke it. Just as he did, Milo stopped
thrusting into his bitch and began to grind down hard, making Stiles gasp and
moan loudly. Derek grinned.
“Aww, Milo’s knotting his little bitch. He’s gonna breed you so good baby
girl.” Stiles whined. “He is. Can you feel it, baby? Can you feel him pumping
your belly full of his hot come, feel it splashing your insides? He’s filling
you up, breeding you, gonna make you swell with his pups and carry his litter.
And he’s going to do it every day, gonna breed you up until it takes.”
Stiles came with a shout as Derek stroked his little, pink cock. Milo just kept
panting and grinding his knot into his bitch, clearly enjoying himself. Derek
held the hand covered in his mate’s come up for Milo, letting him lick it all
up like a treat.
“Milo loves his bitch’s come, look at him lapping it up.” Stiles just groaned,
his head hanging down between his arms. “But now, it’s daddy’s turn to be
pleased, isn’t it baby girl?” Derek said, his wolfish grin back.
Stiles whimpered a bit, both at his words and at Milo pulling his softened knot
out of him and dismounting. He trotted over to his dog bed in a corner of the
room and flopped down, clearly exhausted, but completely blissed out.
Derek got up onto his knees in front of Stiles, his crotch level with his
mate’s face. “Can you show daddy how eager you are for his cock? I know how
much you love it, baby girl.”
Stiles wet his lips with his tongue, making Derek’s dick twitch in his slacks
as he followed the movement with his eyes. His boy’s mouth was made for sin.
He pressed forward eagerly and began lapping at Derek’s cock through his pants,
giving it little kitten licks like it was the sweetest thing he’d ever had.
“Good girl,” Derek cooed, running his fingers through Stiles’ soft brown hair,
the perfect length for tugging on.
He finally unbuttoned his slacks, glad he went commando that day as he pulled
his rock hard cock out. Stiles whined for it eagerly, leaning forward in an
attempt to wrap his mouth around the head. But Derek’s hand was still in his
hair. He gripped it tight and pulled his boy back, making chastising noises.
“Tsk, did I tell you to suck it yet, you greedy little slut?” he demanded and
Stiles had the good grace to look ashamed.
“No daddy, I’m sorry! I just love your cock so much, I’ve been thinking about
it all-“ Derek cut him off, pressing a finger over his boy’s mouth.
“Shhh, I know. And I’m going to give it to you, I promise. But good girls wait
until it’s offered, don’t they?” Stiles nodded, a finger still pressed against
his bite swollen lips. “Good girl.” Derek rewarded him with an intense kiss,
his tongue exploring Stiles’ mouth greedily.
He broke away and gripped his thick cock with one hand, the other still holding
tight to Stiles’ hair. He spread the precum that had gathered at the tip as he
watched Milo fuck his boy around Stiles’ soft lips as though it was lipstick.
Derek smirked down at him. “So pretty, aren’t you, my baby slut.”
Stiles didn’t answer, he just followed his daddy’s dick with his eyes hungrily.
Derek chuckled and finally pressed forward. He moaned as the wet heat of
Stiles’ mouth surrounded the head of his dick.
“Good girl, get my dick wet baby. Get my dick wet so I can fill your pussy with
it.” Stiles whimpered and Derek could see that his little teenaged cock was
plumping up again.
Stiles took his daddy’s dick deeper and deeper into is throat with each thrust
until Derek was fucking into it with abandon. He moaned loudly, loving the
feeling of his boy swallowing around him. “Yesss, take it princess. You love it
when daddy fucks your face, don’t you?”
Stiles moaned, but it turned into a whine as Derek pulled out completely. He
smirked as he poked Stiles in the cheek with his cock, making the boy pout up
at him.
“Now now, don’t make that face babydoll. Daddy’s not done with you yet.” He
manhandled Stiles around until his ass was positioned right in front of his
face. “Such a pretty pussy you have, baby. It’s still soaked with Milo’s come
from when he tried to breed you. But you know what, I bet it’s daddy’s seed
that’s gonna take. I’m gonna fill your little cunt up with my come and breed
you full of MY pups.”
He lightly licked at Stiles’ hole, drawing a moan from the boy, before he
straightened back up, tugged Stiles backwards by his hips and shoved his cock
right into him, bottoming out with one smooth thrust. They both groaned at the
feeling. 
“So full, daddy,” Stiles whimpered, flexing his cunt muscles around the eight
inch cock in him, milking it. Derek was still for several long moments, letting
his mate adjust, before he started pounding him like a jackhammer. Stiles
pushes back into his thrusts, crying out every time Derek’s cock hits his
prostate dead on.
“That’s right, baby girl, scream for me. You love it when I pound your sweet
little pussy with my cock. You take it so well, still so tight even after
playing with Milo all day. And I’m gonna pump you full of my cum, make it so
you feel it splash around in your belly. Gonna plug you up after, make sure it
stays in, make sure it takes.”
He reached a hand around, started playing with Stiles’ nipples through the thin
camisole he was wearing. “I love your little baby titties. Gonna breed you full
of my pups, keep one sucking on your tits while I fuck another into your belly.
Would you like that, baby girl?” Stiles was beyond answering at this point,
only making incoherent noises that drew Derek closer and closer to the edge.
“I know what you want, little slut. You want your daddy to play with your
greedy little clitty again, don’t you?” Derek grinned as he moved his hand from
tweaking Stiles’ nipples down to stroking up and down his pink little cock with
his fingers, treating it as he would an actual clit. Stiles keened and Derek
felt his cunt squeeze his cock tight as his boy come spurted out.
“That’s right. Such a good girl, coming for your daddy. You want daddy’s come
now?” Dazed as he was, Stiles managed to nod still.
“Please, daddy. Please…need it." 
“Of course, baby.”
Derek gripped Stiles’ hips tight and started pounding him with a single-minded
focus. It only took a handful more thrusts before he felt his knot forming. He
groaned as it pushed past Stiles’ rim and locked in, keeping them together.
“Take my knot baby, milk daddy’s cock.” He mumbled, his eyelids at half mast.
The muscles of Stiles’ cunt fluttered around his knot as it exploded in him,
pumping Derek’s come like a fire hose. The flow slowed after a couple of
minutes and Derek looked down, seeing his baby starting to doze off under him.
He knew he should wait, clean them up after the knot went down and feed Stiles
before bed. But right now, cuddling was really all he wanted. So he gently
rolled them both over so they were spooning and bundled his baby tight against
his chest.
He could always clean them up after a nap, after all.
