Summary
     What they were doing – or, more specifically, what Derek was doing to
     Stiles – was far, far from a healthy relationship. Stiles doesn't
     necessarily mind.
     Or, the moment when I began to wonder why my fics always turn to
     scat.
Notes
See the end of the work for notes
When Derek comes in from his afternoon workout – a casual 25 mile run through
the woods of Beacon Hills, at once both a workout and a patrol – he immediately
pulls out his phone.
 
He’s always slightly surprised to see that his most called person on his phone
is Stiles, although by this point it shouldn’t be. Calls or texts like the one
he was about to send came and went almost every day now, sometimes more than
once a day.
 
Tea time.
 
It was an innocent text, to most. Stiles had insisted on it being so, just in
case Scott or Lydia or God forbid the Sheriff were to see a text explaining
exactly why Derek wanted Stiles at the loft. It was already suspicious enough
that Stiles immediately dropped whatever he was doing or whoever he was with
every time Derek texted him.
 
It was getting harder and harder to deny that they were in a relationship, even
though it shouldn’t be. They weren’t dating, is the thing. What they were doing
– or, more specifically, what Derek was doing to Stiles – was far, far from a
healthy relationship.
 
In short, Derek was using him, and Stiles was letting him.
 
                                                                   B rht ther!!
                                                                               
Shaking his head as always at the terrible grammar, Derek put the phone down
and began to strip. He was soaked in sweat from his long run, and whilst normal
people might shower before someone was coming over, that kind of ruined his
favourite part of inviting Stiles over. He liked being dirty and sweaty, and of
course musky, for the kid.
 
He wasn’t sure if Stiles liked it, but eh, he didn’t complain.
 
Deciding to leave his underwear on so as to keep the important part of his body
(for more than one reason) as warm and wet as possible, he stretched out along
the couch, facing the door. There was never long to wait once Stiles responded.
 
Ten minutes later, the door rattled open loudly – practically everything Stiles
did was loud – and then slammed shut once again as Stiles entered. “So, my dad
says he wants you to come over for dinner on Sunday.”
 
Derek raised his eyebrow, staring at the kid. It would be a little rude for him
to just expect Stiles to get straight to work, so he figured it was only right
that he indulge the kid with these little conversations. “Why?”
 
Stiles grinned sarcastically. “Because he’s upset that you haven’t come over
and explained your intentions with me yet. You know, seeing as you’re totally
my boyfriend and everything.”
 
He raised his other eyebrow now. “Your father, too? I thought he knew you were
straight.”
 
Shrugging, Stiles walked behind the couch. “Yea, well, it is a little
suspicious that I keep coming over here for ‘tea’.” God, the kid used air
quotes and everything. He was such a teenager. “And I’m not 100% straight, as
you well know. I’m at least 5% into dudes.”
 
Derek stood up and followed Stiles up the stairs, and into the bathroom. He
didn’t have anything to say to that, so he didn’t respond. Of course, he knew
very well that Stiles wasn’t completely straight – after all, he wouldn’t get
to enjoy this time with the kid if he was.
 
They called it tea time because of what Stiles was doing – for most of his time
spent here, he would just calmly kneel on the floor in front of Derek, sucking
on his balls. Stiles had informed him that that was called teabagging, and the
term had spread from that. And it was always great. The best part, though, was
what came before that.
 
Derek always saved himself for when Stiles could get there, holding it in for
hours. It was better with the kid there.
 
As if he was motioning for someone to take a seat on a throne, Stiles comically
bowed lowly, facing the toilet in the bathroom. Rolling his eyes slightly Derek
moved to stand in front of the toilet, and then faced Stiles.
 
The kid rolled his eyes in turn, huffing slightly as if annoyed, but there was
a slight smirk on his face. He kneeled far-from-gracefully in front of the
werewolf, and pulled down his underwear for him. Derek then sat down and leaned
back against the seat lid, bringing his long legs up and rested them over
Stiles shoulders. It wasn’t the most comfortable position, but it was the one
that worked the best for what they were doing.
 
Essentially, once Derek bent his legs and spread them a bit more, it would
leave him wide open for everything Stiles was about to do. Mainly, clean him up
a bit.
 
Stiles dug in like Derek was a full course meal and he was starving. He started
by laving his tongue over the whole of Derek’s cock, sucking slightly on the
hairs that covered the base of it. The werewolf closed his eyes as he settled
into the situation. He could already feel his muscles relaxing.
 
Stiles had his eyes closed, too, blocking off one of his senses so he could
focus more on the taste and feel. When he felt like he’d adequately cleaned the
outside of Derek’s dick, he moved to the foreskin, slipping his tongue inside
the opening and scooping up the residue from the inside. This part of the job
was always bitter, slightly salty from all the sweat, and was really one of his
favourites.
 
That done, he moved down to the sack. He didn’t spend much time here, knowing
he would soon have them held in his mouth for at least an hour. He’d get to
enjoy it then. He dropped a kiss at the base of it first, before nosing around
the crease. He took a few deep breaths, breathing in the unfiltered man scent
that coated the area.
 
And then he moved farther done, licking along the taint until he ended up at
the track.
 
He paused here, breathing over it, trying to stop the clenching off his
stomach. This was part of there whole charade that he didn’t like, but knew
Derek looked the most forward to. It had taken a lot of convincing the first
time he’d even approached this area of the werewolf, and even more convincing
to get him to where he was now.
 
So it was with reluctance that he leant forward and pressed his nose into the
skin in front of him, taking deep breaths.
 
The smell of shit was unmistakable from this close up. There was no hiding
where Stiles’ tongue was about to be.
 
Derek, as he usually did, lost a bit of control at the slight hint of pressure
against his sphincter. He let out a small fart directly into Stiles’ nose, and
then smiled. Sure, he knew Stiles hated this part, but he had grown so used to
it that he didn’t know what he would do if the kid finally decided he’d had
enough.
 
Stiles pulled pack at the fart, wrinkling his nose. He knew what he was doing,
really – if he hadn’t done it before, the fact that the werewolf basically had
him pinned to his knees in front of the toilet made it obvious. But the smell
and the taste… he didn’t think he’d ever be able to get used to it.
 
Sometimes he wondered to himself why he kept letting Derek do this, but then he
remembered that he had been the one to initiate their odd relationship. He had
never expected it to turn towards this, though.
 
When the fart had dispelled from the air, Derek spoke up. “You weren’t able to
come over the last few days, so I had to wait. It’ll take a little more effort
than usual.”
 
Stiles felt his stomach clench again, and he automatically swallowed the small
amount of bile that came up. Reminding himself that he’d be able to do what he
really wanted to do if he just got through this part, he leant forward again.
This time, instead of his nose, it was his mouth that met the puckered hole.
 
Stiles licked Derek’s ass like he was making out with something precious. He
might not like it, but he went all in on it. At first, he focused on the
outside of the hole, cleaning away the sweat from the run that had pooled
there. He didn’t mind that so much. But then, as he felt the sphincter relaxing
under his efforts, he knew he had to begin going inside.
 
What Derek meant by ‘effort’ was really quite simple. Whilst down here, it was
essentially Stiles’ job to open up Derek’s ass with his tongue, lubing the way
for the werewolf’s waste. Some days this was simple – a few licks, then Derek
would push him away and go. Other days, like when he’d waited awhile, Derek
would keep him close the whole time, wanting more from him.
 
These were the worst days. And this was one of them.
 
Dipping his tongue in with little licks at first, Stiles soon found himself as
deep as he could go in the werewolf’s ass. He could definitely taste the shit
now, coating the walls of the hole, and his stomach was clenching more
forcefully. After a few minutes of laving up the inside, Stiles felt Derek bear
down slightly, and then he felt it.
 
The beginning of Derek’s shit was right at the tip of his tongue. His tastebuds
revolted at the sensation, and Stiles nearly lost it for good there. But then
Derek did something a bit different than he usually did.
 
Using one hand to keep Stiles’ head in place, the werewolf continued to bear
down. Usually this was where the human would pull back slightly, but looks like
that wasn’t going to be a possibility this time. As he was forced to remain in
place, he could feel the shit sliding around his tongue nestled inside.
 
There was a moment where the taste was all-consuming, and then Stiles seemed to
shut down. It was like he wasn’t in his own body anymore – wasn’t the one with
his tongue up another man’s ass, buried in his shit. It made it more bearable.
 
Just when he was sure that shit was going to start squeezing out around his
tongue, Derek let go of his head and allowed him to pull back. He did so
immediately, instinctively swallowing the bits that came back with his tongue.
Knowing what was expected of him at that moment, he used his thumbs to pull the
skin around the hole taut, and waited.
 
When the hole opened, it came out quickly. Just as he’d suspected, the log was
huge – thicker and denser than Derek’s shits usually were. Stiles leaned
forward and licked around it, tonguing the stretched sphincter as it worked to
expel the load, coaxing it out.
 
It seemed to go on forever, and when it was almost done, Derek suddenly pinched
it off.
 
Stiles looked up, confused, knowing there was most likely still more inside.
Derek still had his eyes closed, though, as if he were having some sort of
moment brought on by the feelings he was getting. Thinking that perhaps it had
gotten stuck, Stiles leaned forward to lick more.
 
The hole opened up immediately when his mouth was on it, and he was greeted to
a mouthful of shit. Surprised at having his mouth filled with something solid,
he instinctively chewed a few times, before his brain caught up with his
actions. Coughing slightly, he spit the mouthful out into the bowl below him,
drooling from the saliva brought on by his need to throw up.
 
When he glanced up again, Derek’s eyes were open. They were almost black from
how dilated his pupils were. One of the werewolf’s large hands came towards
him, grasping the strands of his hair, and he was once again pushed towards the
hole.
 
There was still more shit inside, and resigned, Stiles began using his tongue
to scoop out the chunks, swallowing each of them down. Once he was finally,
finally done, he moved away from the inside and continued his cleanup job.
 
He was startled when the werewolf began to stand up, but merely slid himself
out of the way. Derek turned around and quickly took a piss, finishing
relieving himself, and then washed his hands. “I’ll meet you out in the living
room,” he said when that was done, and promptly left the room, closing the door
on his way out.
 
With nothing holding him back, Stiles leaned back over the toilet, staring down
at the logs floating in it. Oddly, he was still feeling that distance that he’d
found, and instead of throwing up immediately as he normally did, he found
himself still.
 
The smell in the bowl was overwhelming, and as if he was in a trance, he found
himself reaching with one of his hands down into the bowl and scooping up a
smaller section of shit. Still in his daze, he brought the log up to his mouth,
and began eating.
 
He ate all of the shit in the bowl like this, not even registering what he was
doing, every few bites taking the time to lean down further in a suck up some
of the piss-water to help wash it down. When nothing remained in the bowl, he
found himself licking the edges of the bowl, clearing off the streaks. That was
when he came back to himself.
 
Immediately, he began throwing up, his body rebelling at what he had just
filled it with.
 
When he was done throwing up, Stiles brushed his teeth with the toothbrush
Derek kept just for him, and then followed the wolf out into the living room.
Now that the worst was over, it was time for Stiles to get nursing.
 
When he entered the room, he found Derek watching him with a strange look in
his eyes, and he blushed slightly, knowing the werewolf had heard everything
he’d just done. Trying to ignore it, he got into place quickly, eager to hide
his face.
 
Nestled up in front of the couch, his face buried in Derek’s crotch and mouth
contently full with the hairy balls, Stiles felt like the bad parts were worth
going through to get to this.
 
~~
 
The next time Derek texted him, Stiles entered the bathroom to find the toilet
freshly filled. Derek watched him this time as he worked to empty it.

     shit in his mouth, though after that all decisions concerning eating
     shit are made by Stiles. In all, though, this fic is completely
