Notes
     WARNING:
     This story contains: Watersports, infantilism, diapering, incest and
     mild scat (because of the diapering). You can interpret it as reality
     (in this series) or as a sexual fantasy and not as something that
     truly happened in my character’s life. The whole series is supposed
     to be a bit ambiguous on the whole “is this real” or “is this staged”
     interpretation.
     More specific warnings at the bottom, but those contain spoilers.
     If any of this triggers you (in a bad way), please don’t read the
     story. I’ve read some stories when I was younger and ignored warnings
     like this one and I really regret it.
See the end of the work for more notes
In a pack like theirs, a close-knit family, it was very common that tasks were
divided between everyone. Taking care of the cubs was one of those tasks and
because Talia and her husband already raised two fine boys, the care of their
youngest children fell on the shoulders of Peter, Talia’s younger brother.
Since the whole pack helped out here and there, it never brought on much
problems, until Derek’s days of potty-training had arrived.
Laura was three years older than Derek and a quick study, so she’ had managed
to be potty-trained before his first memory. When it was Derek’s turn, he was
the youngest child in the Hale pack and therefore the only one still in
diapers. He didn’t really get why he couldn’t just keep them, but Laura was
teasing him about it constantly and although Derek didn’t really mind that,
their parents obviously did.
Derek had always been a bit insecure. He made the most progress when motivated
with positive remarks and deteriorated under pressure. It took a while for
Peter to figure that out.
In the beginning Peter just went at it the same way he had with Laura: he tried
to make Derek tell him when he had to go. That tactic turned out fruitless
however, because Derek always forgot or told him too late and still used his
diaper before they’d reached the toilet. After months of this Peter finally
changed direction. When Derek now messed his diaper he had to walk around in it
for a while so that everyone would know what he did. His other clothes would be
taken so even the humans in their pack would know. Peter hoped that the
humiliation would motivate Derek, but it didn’t exactly work out. Derek didn’t
mind the teasing of the other children or the disapproving looks of the adults
and he still didn’t get why he should go on the toilet. Diapers were way
easier.
So Peter took away all of his clothes and only allowed one diaper a day. If
Derek went, he had to walk around in the mess for a whole day. But that, that
backfired completely.
Derek first grew accustomed to the warm wetness against his cheeks and little
boy balls and after that to the sour stench of urine and poo. He’d also gotten
used to being called names and teased. He wasn’t an unhappy child, it was just
the norm for him. What in hindsight might have had the greatest influence on
his sexual preferences was what Peter started doing around that time. Every
time Derek pooped, Peter would put him on the changing table and pull open his
diaper. Then he’d take his own peewee and would spray milk all over Derek’s
little peewee and his little balls. Derek didn’t understand why his uncle only
ever did it when he’d pooped, but the that was the only moment the stench was
strong enough that the other wolves wouldn’t smell it.
Derek found it all very normal, until he went to elementary school and was the
only one still not potty-trained. He didn’t like wearing clothes again after so
long, but he stopped using diapers the same month. People are a lot meaner when
they’re not family.

Then Kate happened. Derek had liked the young woman who came to his baseball
games and brought him milkshakes afterwards. He also liked that she pushed him
around and made him kneel for her, but they never talked about it. They also
never talked about pissplay. Although Derek fantasized about it regularly, he
didn’t feel entirely comfortable telling her that yet. He never came around to
that.
After the fire Derek lost control. He regressed to an age when he was still
happy and surrounded by pack. He was definitely not potty-trained anymore.
Laura took him with her to New York, because she could hardly leave him behind
with their comatose uncle, could she. She had to put him back in diapers and he
refused to wear any kind of clothing, and although she loved her brother she
just couldn’t take it some days. Derek seemed unfazed by her yelling though. If
anything, it aroused him. Since he was a big boy now, he learnt of the sexual
side of his fetish. The pissplay he never got around to with Kate was only the
tip of the iceberg. His favorite thing was pushing the soaked material of his
bursting diaper against his dick, then shoving his hand inside and fondling
himself until he came. Afterwards he’d pull out his hand and lick off all the
piss and cum. Yeah, Derek was happy.
One day when Laura had come home from a late shift at the coffee shop to cover
for their expenses she found him on the couch, in the exact same position she’d
left him in hours ago. He was awake, blinking up at her, as she broke down
crying. He’d had a leak an didn’t do anything about it, just kept going in his
overly full diaper until it was dripping on the carpet. They threw both the
couch and the carpet out.
From that day on, Laura started treating Derek like a real baby. She figured
that she would probably be able to handle a baby better than a teenage brother
with a mental problem and she was right. Her werewolf strength made everything
simple enough. The only thing it couldn’t help her with was breastfeeding. So
she gave him a bottle with milk, mixed with her urine, because she knew it’d
make him docile. Derek agreed wholeheartedly. He’d lay with his head in her
lap, gazing up at her and suckling happily on the nipple while cuming in his
diaper without even being touched. Every single time Laura fed him, Derek came
because of the taste of piss in his milk.
After years of this, Derek relearned how to speak. He kept wearing only
diapers, because he still didn’t see the use of going without them. One night
when Laura was feeding him, Derek asked her about uncle Peter. With tears in
her eyes Laura told him the man would forever be a plant, but Derek shook his
head. He explained he just wanted to taste uncle Peter, too. After all, Peter
had given him his ‘milk’ almost every day when he was a real child, so he
didn’t see why he couldn’t have it now.
Laura left the next day and never returned. Derek was forced to grow up
mentally in less than a week. It messed him up, and he definitely wasn’t ready
to become alpha. But now, after all of that, he had finally settled down and
with Stiles to be his little puppy, he had everything to be happy.
End Notes
     SPOILERS:
     This story is about Derek’s potty-training. Derek is heavily underage
     in the first part of the story and only sixteen and counting
     afterwards. It contains incest (Derek x Peter, Derek x Laura). They
     both humiliate Derek, although he likes it. Peter masturbates on him
     as a child and Laura feeds him her urine when he’s a teenager and
     treats him as an infant. The whole story is about diapering and
     humiliation, so bodily fluids are present practically the whole time.
     I don’t like scat, though, only the aspect of diapering appeals to
     me, so there are no really graphic descriptions of that here (I
     think).
     In no way am I trying to promote child abuse or rape. A parent of
     family member should never take advantage of a child or (mentally)
     disabled person. This is merrily a fantasy that is completely
     fictional.
