Crave the Knot - Chapter 1: The Pet

Jake awoke slowly.  The young man had been stuck in a state of
semi-consciousness and wakeful dreaming for some time.  When his eyes
finally opened, he was aware he was not in a familiar place.  Light was
coming in from a window across the room, and he saw that he was inside a
metal kennel meant to hold a large dog.  It was then that the previous
evening's memories started coming back.

It had been a Friday night, and the boy had just finished a long day at
work and needed to unwind.  Jake was twenty-two years old, five-foot-eight
inches tall, and had a furry body with dark hair and brown eyes.  He had
been in the pup scene for a while and had amassed a lot of gear.  His
colors were red and white, and all his toys were color-coordinated.  He
first slipped on his dog mask before putting the leather harness over his
chest and attaching his rubber tail to the belt that held up his tight
jeans.  The final step was to put on his chainmail collar with the tag that
read "Pup Zero".  He barked in the mirror and wagged to himself before
walking down the street to the bar.

It was still early when he entered the leather bar, and he didn't recognize
anyone he knew.  It was happy hour, so he ordered a few drinks and downed
them quickly as he waited for the evening crowd to arrive.  He had been
there only about thirty minutes when a large, muscled man with a hairy
chest sat next to him.

"What's up, boy?" the man asked.

"Not much, Sir," Jake replied.  "Just trying to relax for the weekend."

"I see!" the man replied.

"My name is Jake," the boy replied.  "But I also go by Pup Zero."

"Nice to meet you, Zero," the man replied.  "My name is Kevin, but you can
keep calling me Sir."

"Yes, Sir!" Jake replied.

"How long have you been a pup, boy?" Kevin asked.

"Since I was in high school," Jake said with a smile.  "I'm a big bottom
pup.  I love to get into the headspace."

"Is that right?" Ken asked.

"Yes, Sir!" Jake replied.  "I am big into bondage and hypno sessions.  I
can also do chastity and am interested in stretching my hole so I can take
bigger bones."

"You sound like you can be pretty kinky," Kevin said as he ordered a drink
and stared at the boy.

"Oh, yeah," Jake replied.  "I am still young, but I have done a lot of shit
over the years.  I love to be dominated and told what to do.  Ultimately, I
would love to have a master one day."

"And would you be willing to give up your life to live and serve him?"
Kevin asked.

"Oh yes!" Jake replied.

"No matter what he asked you to do?" Kevin asked.

"What do you mean, Sir?" Jake asked.

"Well, if a dom put you in chastity and made you act like a dog all the
time, would that freak you out?" Kevin asked.

"Actually, that might be hot," Jake replied.

"I bet you would be a good full-time pup," Kevin said.  "You have a cute
body.  Ever had a real dog mount you?"

"Umm," Jake replied as he looked down.

"Is that a yes?" Kevin asked.

"Well, once, Sir," Jake replied.

"Did you like it?" Kevin asked.

"It was interesting, though I could not take the knot," Jake said.

"You just need to work at it," Kevin replied with a wink.  "I bet you could
learn to love the knot."

Jake smiled and laughed apprehensively, and Kevin kept eying the boy.

"Am I making you nervous?" Kevin asked.

"No, Sir," Jake replied.  "I am just not used to anyone being this open
about such things."

"I see," Kevin replied.  "So, if you were taken home and used as breeding
stock for a couple of dogs, would you freak out?"

Jake took a drink before answering.

"It might be fun, depending on the situation."

"Fair enough," Kevin replied.  "I could see a hot dom collaring you, taking
you home, stripping you of your humanity to treat you as a pup, and letting
his dogs breed you.  I think you would like it."

Jake smiled and stood up.

"Will you excuse me, Sir?  I need to piss.  Can you watch my drink for me?"

"Oh, I will be happy to keep an eye on it for you," Kevin said with a
slight grin.

Jake slipped away to the bathroom, and when he returned, he saw that his
glass had moved and was now full.

"Accidently knocked your glass over, boy," Kevin said.  "Ordered you a new
one.  I hope you don't mind."

"Not at all!" Jake said as he sat back down.  "Thank you for that."

Jake sipped his drink and noticed that it tasted slightly off.  However, he
had already drank two of them, and they poured heavy here, so he thought it
was just his imagination.

Kevin began to ask the boy questions about his life.  At first, it was
mundane things like where he worked, how long he had been in the city,
whether he had friends and family, and whether he had roommates, but it
quickly turned to sexual questions.  Jake quickly opened up about his
fantasies of serving a master.  Kevin got him to think about being a human
pup.  They discussed him being forced to live on all fours and living a
dog's life.  Kevin mentioned he had two dogs of his own with huge dicks and
how it would be hot to see Jake take their knots.

As time progressed, Jake started to find he agreed with everything Kevin
was asking him.  He was getting aroused as well.  He could feel his cock
swelling in his pants, and Kevin reached over and rubbed his crotch several
times.  He began to feel warm, too.  The room started to spin, and he lost
track of time.  Kevin seemed to loom over him, and, at one point, the man
reached out and steadied the boy to prevent him from falling off the chair.

"I think you have had enough alcohol, Zero," Kevin said.  "You should come
home with me."

"I think I should, too, Sir," Jake had immediately replied without
thinking.

Kevin smiled before paying their tab and leading the boy into a black
truck.  After that, there were gaps in his memory.  He recalled arriving at
Kevin's home and being told to strip his clothes off.  He knelt on the
floor in front of the man willingly and asked to be treated as a pup.  The
next memory was Kevin asking him to beg to be put into chastity and serve
him, and Jake immediately complied without question.  The boy soon felt
cold steel encasing his cock and balls.

"Good boy, Zero," Kevin said.  "Now show me those paws."

The man strapped ball mittens to his hands and put knee pads on him before
pulling his feet up and binding them to his thighs with leather straps.  He
was now forced to walk on all fours, using his knees as his back paws.  A
large tail plug was forced into his ass, and then Kevin removed the snout
from Jake's mask and placed a ball gag in his mouth that had a tube hanging
from it.  Once it was secure, he snapped the nose back on, and the look was
complete.

Jake could hardly believe what he was letting this man do to him.  It was
like he could not resist any command he was being given.  He felt the fog
in his brain starting to lift, but Kevin soon placed a bowl on the floor
with a strange green liquid in it.

"Your gag has a tube in it, boy," Kevin said.  "Place your snout in the
bowl and drink it all.  I know you are thirsty."

Jake immediately moved over, put his head into the bowl, and sucked the
fluids through the tube.  As they entered his mouth, he noticed that it
tasted stronger than the drink he had been given at the bar.  Still, he
complied.  He had to.  He finished off all the liquid, and the room spun
again as he lifted his head.

"Good boy, Zero!  I accept you as my pup.  You belong to me now."

It was the last thing he remembered hearing before passing out.

As Jake took stock of his surroundings, he noticed he was still in the pup
gear he had been placed in when he arrived at Kevin's house.  His tongue
darted around the ball gag in his mouth that was firmly secured around his
head.  His mouth was dry, and he had a slight headache.  As he got up, he
felt the cramps in his legs.  They were still bound tightly to his thighs.

Jake groaned and felt the butt plug portion of the tail in his ass.  It was
larger than the toys he had used at home.  As he looked up, he saw a note
pinned to the front of the kennel.

Good morning Zero.

I hope you slept well.  I am so pleased to have you as a permanent part of
my household.  I have big plans for you!  You will find your breakfast in
the kitchen.  I will return around lunchtime to see how you are doing.

Your Owner and Master.

"Owner and Master?" Jake thought.  "I just met this guy.  Who the fuck is
he?  What the hell have I gotten myself into?"

Jake pushed on the door to the kennel, and it swung open.  As he carefully
crawled out, balancing the back half of his body on his knees, he felt the
metal chastity cage below him swinging from side to side.  He pushed his
head under his body to look at it and saw that his cock had been shoved
into a tiny metal prison.  Only the tip of his penis was showing, and
barely at that.  A ring firmly trapped his balls at the base, so it was not
coming off without the key.

Jake moved across the room and went through an open door into a hallway.
At the end, he could see the kitchen.  He passed a living room and a
bathroom as he made his way down to it.  Once he crawled onto the linoleum,
he saw two dog bowls on the floor.  A note next to them said, "for Zero".
One bowl had water, and the other contained what looked like cream of
wheat.  Jake stared at the bowls for only a moment.  He was thirsty and
dipped the tip of the tube from his ball gag into the bowl and drank half
of it.  He then moved over to the second bowl and found that the tube was
wide enough for him to suck the contents up quite quickly.  It was plain
but delicious, though it had a faint chemical taste to it.

When he had finished both bowls, he looked around the room and noticed a
large dog flap in a door to the back of the kitchen that led to the
outside.  The rest of the room was clean and sterile.  Jake turned and
crawled back down the hall and investigated the living room next.  The TV
came on automatically as he entered, which scared him at first.  He looked
around and saw no one else in the room, and when he turned back to the
screen, he saw what looked like a porno being played.

In the video, a boy was dressed in gear similar to his.  The young man had
a large tail in his ass that had a ring at the base.  Jake looked behind
him and saw his tail was made the same way.  The boy in the film was in a
small room.  He crawled over to the wall and used a special hook embedded
in it to latch on to the ring, and by moving forward, the boy could remove
his tail.

"Good boy!" a voice said.  "Now it is time for the pup to train his cunt."

The boy turned around and pointed his ass towards what looked like a giant
dildo attached to a metal device.  As he backed onto it, Jake could see
that the toy flared out near the base.  The boy had some difficulty, but
when he finally could push down onto it, the device made a sound, and the
boy groaned in pleasure.

"That is a good pup," the voice said.  "As a reward, you will now feel
pleasure."

The boy's body was visibly shaking, and Jake saw that his cock was also in
a chastity device.  The camera went in for a closeup, and Jake could see
the boy's cock head was swollen and pressing on the bars to his cage.  It
dripped precum in thin lines that accumulated on the floor below him.  The
boy groaned.

"That is a good pup," the voice said.  "Relax your cunt."

Whatever the device was doing, it must have felt good.  In less than a
minute, the boy was shooting ropes of cum onto the floor below him.

"Good dog," the voice said.  "Good dog."

The picture turned black, and Jake looked down and noticed that his cock
was straining in the cage that encased him.

"Look to your left, boy," the TV said.

Jake was confused.  The screen was still blank, but the command came again.

"Look to your left, boy.  It is time for Zero to train his cunt."

Jake turned to his left and saw that there was a hook, just like on the
film, embedded in the wall opposite him.  Across from it, also attached to
the wall, was a device with a phallus that looked similar to the one the
boy in the film had used.

Whatever had been in the food he had consumed had left his body warm, and
he was horny.  If the boy had experienced pleasure from the device, surely
it could do the same for him.  Jake crawled over to the device to inspect
it closer.  The phallus was shaped like a dog's penis and had a knot at the
base.  It glistened in the light of the room.

"It is pre-lubed!" Jake thought.

The boy looked closer and noticed that the dildo was connected to two
suspended containers that looked similar to an enema bottle.  There was a
great deal of other wiring and tubing around it, and Jake wondered what all
it did.

"It is time for Zero to train his cunt," came the voice from the TV again.

"I need to try this," Jake thought as he looked at the hook and pointed his
ass towards it.

It took the boy some maneuvering to catch the loop at the base of his tail
on the mounted hook, but when he succeeded, he crawled forward and felt as
the plug popped out.  Jake groaned.  His ass felt empty after carrying the
large tail for so long.  He needed something to replace it.  The boy spun
around and pointed his ass at the red dog phallus.  It was mounted at the
perfect height for him to back onto it.  The lubricated tip slipped easily
into his hole, and he rocked his haunches back and forth on the mounted
dildo, enjoying the pleasurable sensations it was giving him.

"Good dog," came the voice from the TV.

The device then made a noise and started to move.  It was slow at first,
but it quickly started to vibrate back and forth and pushed deeper into his
ass with every moment.  Jake felt the movement over his prostate, and his
caged cock started to leak precum heavily.  He backed father onto the
gyrating toy until he reached the knot.

"Fuck," Jake thought.

"Take the knot, boy!" came a voice from the TV.  "All dogs crave the knot.
You are a dog.  Just a dog.  You want the knot.  Take the knot!"

"I want the knot," Jake thought as his body felt warmer.

"You are a dog.  Just a dog.  You want the knot.  Take the knot!" the TV
continued to say.

The boy pushed back and felt as the bulbous end started to stretch his ass
lips.  As the device moved back and forth, he noticed it felt wet.  A
lubricating fluid was being pumped into him, and his ass was soon slick and
accepted the knot deeper.

"You want the knot," came the voice from the TV.  "Take the knot."

"I want the knot," Jake replied without thinking.

The boy pushed backward and felt pain as the large ball passed into him.  A
rush of endorphins soon followed as he slid farther back, and it embedded
completely in him, tying him to the toy.  The device then made a sound and
started to buzz.  Air was pumped into the knot, and it began to grow.

"Oh, fuck!" Jake thought, but it was too late.

The knot had grown so large that it was not coming out.  Then the
vibrations began.  They hit his prostate directly, and he groaned in
pleasure.  He felt warm fluids being pumped into him from a separate tube
just as cum poured from his caged cock.

"Fuck!" Jake groaned into his gag.

"Good dog," came the voice from the TV.

Stars exploded around the edges of Jake's vision as his body went into
overdrive.  He began to make unintelligible noises as his orgasm crested
and subsided.  Then, suddenly, the device stopped.  Jake panted like a
bitch in heat.  He realized he would be stuck to the wall if he did not
pull himself off the toy.  But the knot was so large.  Just then, the
device made a sound, and the air started to release.  The knot decreased in
size, and Jake had his chance.  As he leaned forward, he felt the knot deep
inside him.  It hurt, but he finally managed to dislodge it, and when it
fell from his ass, fluids leaked out of him and dripped down his caged
balls.

Jake hung his head and gathered his thoughts.  The afterglow of his orgasm
had been intense.  Far more intense than he had ever experienced in his
life.  He squeezed his ass and felt the liquids filling him.

"Fuck," Jake groaned.  "I want to do that again!"

Jake backed his ass onto the toy again, but it did not move or make any
noise.  He rode it for a minute before the voice from the TV spoke again.

"It is time for Pup to go outside.  Pup needs to piss.  Pup is thirsty."

The boy was thirsty again, and he noticed how full his bladder was.  He did
not remember the last time he took a piss.  He crawled through the room and
entered the kitchen.  The dog flap was large enough to accept his body.  He
moved over to it, pushed his head through the flap, and saw a nice grassy
backyard with a fenced dog run of about 50 to 60 feet on the left.  There
was another similar one to the right.  A wooden building took up the back
of the yard, and most importantly, he saw a waist-high trough with a
running hose at one end.

"Fresh water!" Jake thought.

The boy pushed through the dog door and heard it clatter behind him.  He
then made his way down to the grassy area and squatted.  He felt the warm
stream of piss fall from his cage, and he groaned in pleasure as his
bladder emptied.  When he was done, he crawled to the back and made his way
to the trough.  He was within six feet of it before noticing the dogs in
the neighboring cages.

Two slumbering, hulking beasts lay in the morning sun: a gorgeous German
Shepard and a Great Dane.  Jake froze.

The Shepard twitched an ear at the sound of his movement, but otherwise,
the dogs were sound asleep.

"I'm glad there is a fence here," Jake thought.  "They look friendly, but
you never know."

Jake continued to the trough and placed his tube into the water.  It was
cool and sweet.  He drank his fill and raised his head.  The two dogs had
awoken and were on their feet.  They came to the fence and were panting.
Their ears were laid back, and they were confused.  Jake slowly moved to
the fence, and the dogs pressed their noses through the gaps in the metal
chain links and started to sniff the boy.  Jake tried to return the gesture
in an attempt to say hello.

Jake looked at their collars and saw that the German Shepard was named
Bruce, and the Great Dane was named Tank.  As he tried to continue to be
friendly, he noticed that the dogs started to look agitated.  They pawed at
the fence, and Tank started to growl.  He paced back and forth and looked
at Jake's ass.  The boy turned slightly towards the fence to see what they
were looking at, and Tank reacted by starting to sniff and make more
noises.

"I bet you smell that fluid that that toy pumped into me," Jake thought.
"I don't know what it was, but it sure has you curious."

Jake smiled, spun around, and pushed his ass towards the fence, and the
dogs went wild.  They started to lick through the chain at the boy's skin.
Bruce poked his snout through a gap, and his long, sloppy tongue roped out
and lashed at Jake's abused cunt.  Fireworks exploded behind the boy's
eyelids, and he moaned like a bitch in heat.  Jake pressed his cunt hard
against the fence, and Bruce's tongue flicked through the gap, striking his
hole, and forcing its way inside.  The wet, rough tongue slurped at his
sloppy hole, and Bruce's urgency intensified.  Tank came over to inspect
and seemed to be similarly riled up.  Both of them wagged their tails
intensely.

Bruce's long, wet tongue continued to flick and tease Jake's hole, which
spasmed in response, still dripping fluids from the gut injection he had
received from the device inside.  The boy groaned and dropped his face to
his forearms.  The large dog was eating his sloppy cunt, which felt like
heaven.

After a few minutes, the attention started to make his hole a little too
sensitive.  Bruce's tongue was rough and began to hurt the boy despite the
slobber and lube still dripping from Jake's cunt.  His body was hot, his
head was spinning, and Jake was horny.  He crawled away from the fence and
back to the trough and dunked his whole head in, holding it under water to
enjoy the cool shock of the chilly water.

Jake heard a clatter, pulled his head up from the trough, and shook the
water away.  Turning around, he saw Bruce on `his' side of the fence.  The
dog had entered through a flap the boy had not seen on the outside of the
wooden building.  He then saw Tank push through the door and join Bruce,
and the boy panicked.

Jake crawled to the kitchen door, but the dog flap was a one-way
contraption.  With his mittened hands, he could not lift the flap, so there
was no way he was getting back inside.  He turned to the yard and saw the
two huge dogs advancing towards him, obviously curious at this new addition
to their living space.

The boy backed up towards the brick side of the house and cowered.  Bruce
paused, then moved towards him slowly, sniffing and licking his dog mask in
a greeting.  Tank joined him, and they seemed friendly.

Jake moved a few steps forward, and Bruce immediately circled behind him.
His tongue sought the boy's cunt hole and began lapping at the fluids.  At
the first taste, Bruce became noticeably excited and pushed his snout and
tongue deep into the boy's hole.  Whatever was in the liquid that had been
pumped into him was driving the dog wild.  Jake moaned and pushed back
towards the animal.  He then closed his eyes and enjoyed the sensation.

A nagging thought then dawned on the boy, pushing its way through the fog
of lust and mild euphoria.  It was the full realization that he was acting
and presenting himself as a horny little bitch.  His head jerked up with
the recognition of his dangerous position.  At that exact moment, Bruce
reared up and landed on his back.  The beast's warm chest pressed into the
boy as his front paws locked around Jake's hips.  The boy struggled against
the dog, trying to get away, but Bruce had the advantage of surprise,
position, and body weight.  The animal's hips began to thrust forwards, and
Jake felt the tip of Bruce's rapidly hardening prick slipping between his
ass cheeks.  There was no resistance in his lubed and loosened state, and
he could not stop the beast from slamming his engorged cock inside.

Sensing his victory, Bruce doubled down on his grip of the boy's hips,
hunching against him harder, feeding more of his dog cock into Jake's ass
at a frantic pace.  The boy then remembered the similar feeling that the
dildo had given him earlier.  He groaned in defeat and pleasure as Bruce
raped his bitch cunt.  The depravity of the situation added to the heat and
sensations flooding his body as Bruce plowed him.  The dog was claiming
Jake's ass for his own.

As Bruce forced himself deeper and deeper, the boy felt a bulge at the base
of the dog's cock banging away at the entrance to his hole.  The beast was
not gentle, and it felt enormous.  Jake panicked again and struggled to
escape, but it was no use.  The animal had him.  He had to submit.  He was
just a dog.  He craved the knot.  He needed the knot.  He had to have the
knot.

The last resistance in Jake's sphincter gave out, and the bulge in Bruce's
cock popped inside.  White-hot pain mixed with the feelings of pleasure in
the boy's mind as Bruce sawed his knot in and out.  The dog gripped Jake
tighter, redoubling his efforts to breed.  Bruce slammed into the boy again
and then froze in place.  His chin rested on Jake's shoulder as he panted
in the boy's ear.  Jake felt his already enormous knot further expand in
his ass, stretching him even more than his time on the dildo earlier.

Jake could feel Bruce's cock pulsing.  It throbbed each time the beast's
cock jumped.  Bruce had tied Jake.  He had made the boy his bitch, and now
he was pumping him full of his cum.  Jake imagined that he could feel the
dog's warm seed jetting into him, filling his ass and breeding him with his
pups.  The throbbing in his ass seemed to grow in intensity.  Jake closed
his eyes and rested his head on his forearms.  His universe revolved around
this stud dog's pulsing knot.  He needed the knot, though.  He was just a
dog.

A tingling sensation grew from deep between Jake's hips, overtaking his
consciousness and spreading throughout his lower body.  The boy's legs
began to shake, and his arms quivered.  Waves of warm pleasure emanated
from his cunt and spread throughout his lower body.  Bruce twitched and
turned.  He threw his leg over Jake until he was ass-to-ass with the boy,
causing a few brief tugs on the buried knot inside.  The movement caused
waves of pleasure, and Jake cried out into his gag.  He couldn't breathe.
From deep in his balls, the boy felt the release of fluids.  He could feel
them shoot up into his groin and come spurting out of the tip of his
metal-encased cock.  He sprayed cum into the grass in three massive jets
and groaned helplessly as he orgasmed.  His ass clutched and spasmed around
Bruce's colossal knot.

Jake floated, lost and helpless in darkness.  He didn't know how long he
drifted.  The only awareness he had was the pulsing bulge buried in his
cunt.  He was centered on Bruce's shaft.  He couldn't form coherent
thoughts, and his body felt spent and weak.  He felt like he was being held
up by the giant dog cock that skewered his core.

Bruce shifted again.  He was growing impatient.  The animal gave a few
exploratory tugs that caused shockwaves of pleasure to course through
Jake's body.  Bruce's cock was still pulsing within the boy as he panted.
But at length, he yawned, licked his chops, and decided that he'd had
enough.  The dog began to pull away from Jake, and the boy could feel his
knot being dragged out of his ass.  It had shrunk slightly but still felt
enormous.  Jake relaxed his ass as best as he could and yelped in pain as
the knot finally popped free.  The boy turned and saw the dog's cock
swinging pendulously from his belly.  Bruce's angry-looking knot was the
size of a balled fist.

As Jake struggled to catch his breath and deal with the fiery burn that
emanated from his abused asshole, he wondered at the length and size of the
tool that had held him at its mercy.  A thin fluid stream leaked steadily
from his ass, down his caged ball sack, and began to drip onto the ground.
Jake experimented with tightening up his ass to stop the flow, but there
was too much cum inside him, and his cunt felt swollen.  It wasn't
responding.  Jake didn't see any blood, though.  So, that was a positive.
He was exhausted, however.

That's when Tank approached.  Jake moved away as quickly, but the dog
followed.  Tank's long tongue chased him, lapping at his hole, slurping the
leaking fluids off his bound balls.  Jake kept crawling away, circling as
best as he could.  He could see the tip of Tank's cock hanging down.  It
looked much larger than Bruce's dick.  He had no desire to go a second
round with an even more giant brute.  He feared he would not survive
another assault without incurring some severe damage.  He kept up his
attempt to escape Tank's attention, but the dog had no challenge keeping up
with the boy.  Jake knew he couldn't run from the dog forever, so he tried
flopping down onto the ground, laying on his side to hide his cunt from the
giant.

Tank stood over the boy, obviously confused and frustrated.  The dog
alternated between licking at the boy's sloppy hole and nudging him with
his nose.  The tip of his cock was no longer hanging but stiffly pointed,
and Jake could see the start of a bulge farther back in his sheath.
Eventually, Tank lost his patience.  The dog growled low, and its rumble
filled the boy with fear.  Tank straddled Jake and leaned down to grip the
boy's neck with his massive mouth.  He did not bite down, but he was making
his intentions clear.  It was his turn, and he would have Jake one way or
another.

"You are just a dog," came the voice in Jake's head.  "You crave the knot.
You want the knot!"

The boy struggled to his hands and knees, and Tank released him and went
back to sniffing at his ass.  After a few more licks, he reared up and
mounted the boy.  The size mismatch made it an awkward endeavor, but the
dog was a determined beast.  His long forepaws gripped Jake tightly,
wrapping around the boy's waist as the beast bent and thrusted his cock
towards Jake's cunt.

Eventually, Tank found his mark, which sent him into overdrive.  He
thrusted and pushed deeper into Jake's hole.  The boy wouldn't have been
able to stop him if he had tried.  The animal was huge and powerful.  Jake
knew from seeing his much larger cock that he wouldn't survive attempting
to resist being knotted.  If the beast tried to saw his bulge in and out of
him as Bruce had, the boy would surely reach the breaking point.  Jake had
only two choices.  He could resist and risk getting seriously hurt.  But he
knew he would be unable to hold him off in his weakened state.  Or he could
submit willingly, please this stud, and try to avoid getting injured.

Jake knew what he had to do.  He was just a dog, after all.  Tank
jackhammered into the boy, getting deeper and deeper as the beast's grip
tightened.  The instant Jake felt Tank's knot hit his asshole, the boy
pushed back with all his might.  As the dog thrusted, Jake forced his ass
out and pushed as if he was passing a massive shit.  It worked.  Tank's
knot popped into the boy with a soul-searing thrust on the first try.  Jake
nearly passed out but clamped down his sphincter as best he could to keep
the dog inside him.  Tank then slowed his frenzied thrusting.  Now he was
just trying to get deeper.  The pressure from Jake's ass triggered him, and
his knot began to balloon inside the boy.  It quickly surpassed the size of
Bruce's knot and kept expanding.

The pressure and intensity of the burning sensation drove all the air from
Jake's lungs.  The boy let out a guttural, animalistic groan.  He was well
and truly stuck.  He could not move an inch forwards or backward.  Tank
growled a low response to the boy as he froze too.  His knot filled Jake's
ass, and the boy was sure he would burst.

The pressure in the boy's cunt peaked.  The throbbing he had felt during
Bruce's tie was intense, but he didn't know how to compare the difference
to the sheer impossible size of Tank's knot buried in his ass.  His
prostate was crushed from the inside, and a steady trickle of precum was
oozing out of his tiny bound cock as he struggled to breathe.  Tank shifted
and tried to push deeper into the boy's hole.  Jake thought it felt like
the dog was rearranging his insides.  He could feel every inch of the
enormous prick.

The knot stopped growing, and then the pulsing began.  Each throb that
emanated from Tank's cock seemed to set off micro-explosions in Jake's
cunt.  The boy twitched uncontrollably, moaning, and groaning from the
pressure and the overwhelming sensation.  The entire world disappeared.
Jake existed only as a sheath around this massive weapon.

This time there was no imagining it.  The tight squeeze made Jake feel
every powerful spurt of fluid Tank sent into him.  Each time the beast's
cock jetted fluid into the boy's guts, his entire body twitched in
response.  Tank's cock was a burning mass of heat, and his cum was liquid
fire in Jake's cunt.

The boy felt a building sensation, slower than the first one with Bruce but
inevitable in its arrival.  Each jump of Tank's prick pushed the boy on a
slow march to the edge.  Jake teetered on the edge for a moment, then a
blaze of molten heat built at the base of his bound cock and blossomed into
a firestorm.  He was thrown from the cliff in a full-body explosion.  His
orgasm rocketed the boy into the abyss.  Jake's tiny cock exploded, spewing
a fountain of cum and he lost awareness of his body completely, utterly
overwhelmed by continuous, unrelenting waves of pleasure.  Each pulse
pushed him further into oblivion, and the boy screamed into the gag as he
was destroyed.

In the moments afterward, Jake was senseless.  He struggled to piece
himself back together and find his way back into his mind.  He had nothing
left, no energy, no will.  He was just a dog.  He was barely propping
himself up, reeling under the weight of Tank and held aloft only by the
dog's iron shaft.

Jake's body quaked and quivered in the aftermath.  His breathing returned
and then the awareness of his cunt.  He had no idea how long had passed,
but Tank was still jetting his seed into the boy's ass.  After an eternity,
the spurts slowed, but the pulse of the dog's heartbeat still resounded
through Jake's body.  The boy's caged balls felt like they had turned
themselves inside out, and his entire lower half ached.

An age passed, and then Tank stood.  Jake was still transfixed by the
beast's cock, speared, and stuck, completely unable to move.  The dog was
patient, used to waiting for his knot to shrink to get it out of whatever
lucky bitch he had decided to make his own.

His first movement was slow, but it reinforced how the orientation of
Jake's body had been changed.  He was no longer on all fours facing
forwards.  He was on his hands and knees, but `forwards' for the boy was
now the direction of the dog's cock.  Tank was Jake's lord and master.
Forwards was wherever he chose to go.  The dog quickly stepped over Jake,
swinging his leg, and turning casually to face away.  His massive cock spun
inside Jake's cunt but was locked in place by his enormous knot.  If he
tried to pull out as Bruce had, the boy would be destroyed and turned
inside out.

Tank took a half step away, and the tugging of his knot made it clear Jake
had no choice.  The boy scrambled backward after him.  The dog slowly made
his way to a patch of grass in the shade of the hut and began to lay down.

Pain erupted from Jake's ass as his body was pulled to the ground.  The boy
flopped down, exhausted, still tail to tail with this behemoth as the dog
lay down and stretched himself out.  Jake whimpered in pain as Tank's knot
tugged at his guts again.  He tried to get as close as possible to the dog
to relieve the pulling pressure on his hole.

At last, Tank stopped moving.  The dog rested and basked in his victory,
his claiming of a new bitch.  Jake laid on the grass, unable to form
comprehensive thoughts as fatigue washed over him.  Bruce wandered over and
laid down on the grass next to them.  The dog went right for Jake's caged
cock and balls and started to lick the cum that coated them.  The boy
spread his legs and let the dog do what it wanted.  He was exhausted, and
he closed his eyes and passed out.

When Jake finally opened his eyes again, the two dogs were gone.  He was
lying in the grass.  His gaping cunt was dripping cum.  He was sore and
thirsty, so he rolled onto his hands and knees and crawled over to the
water trough to suck down some refreshment.

"I see you were claimed by the dogs, Zero!" came a voice from behind him.

Jake spun around and saw Kevin standing near the house.  The man wore a
pair of tight jeans and a t-shirt but was barefoot.  He had a cigar in his
mouth, and he sucked on it and blew out a cloud of smoke before speaking
again.

"Come here, boy."

Jake paused and did not know what to do.

"I said, come here, boy!" Kevin said more firmly.

Jake crawled to the man and then bowed his head.  Kevin reached down and
patted the boy's back and inspected his body.  There were long scratch
marks down Jake's sides from the dew claws of the beasts, and Jake's fur
was matted and crusted with sweat and cum.

"You made quite a mess of yourself," Kevin said.  "I think you need a bath.
Come with me, boy."

The man walked over to the back of the yard and entered through a door in
the wooden building, and Jake followed.  Inside, Bruce and Tank were lying
down on large blanket-covered hay beds, sleeping.  They opened their eyes
when they saw their master enter.  Walking over to him, Kevin petted them
and praised them.

"Good boys!  You bred your bitch well, didn't you?"

Jake watched from the side as Kevin grabbed some soap and a sponge from a
shelf and returned outside.  A large metal basin was in the corner of the
yard, and Kevin filled it halfway with water before beckoning Jake over.
He then leaned down, picked the boy up, and put him into the tub.  The
water was cold, and Jake shivered as Kevin put soap in and began to clean
the boy with the sponge.

"You need to ensure you are presentable for your studs," Kevin said.
"After all, they will be using you from now on."

Jake groaned and struggled, but Kevin grabbed the harness around the boy's
chest and held it firm.

"You are mine now, boy," Kevin said.  "Your former life is over.  You are
just a dog.  You crave the knot.  You want the knot.  Bruce and Tank will
give you the knot whenever they want."

Jake cried into the gag.  He recognized Kevin's voice now.  It was the
voice from the TV.

"Don't worry," Kevin said as he pulled a syringe from his back pocket.  "I
will keep you drugged for the first few weeks to help you acclimate.  But
the sooner you accept your fate, the better off you will be."

Keeping one hand on Jake's harness to hold him in place, Kevin pulled the
tip off the syringe with his mouth and then plunged the needle into the
boy's ass.  Jake felt the injection's pain and then the drug's warmth as it
flooded his body.  His inhibitions started to go away.  He did not care
anymore where he was.

"You are just a dog," Kevin said as he tossed the syringe on the ground and
finished bathing Jake.  "Just a female dog.  You are a bitch that craves
the knot.  You want the knot."

"I am just a dog," Jake thought.  "I want the knot."

Kevin moved under the boy and sponged around the chastity cage that encased
Jake's cock and balls.

"I am glad you were able to get off from being fucked in your cunt, boy,"
Kevin said.  "You don't need those balls or shaft to experience pleasure.
You are a female dog now.  Your pleasure organ is your cunt.  You are a
bitch to be bred."

"I'm just a bitch to be bred," Jake thought.

Kevin could see how relaxed the boy was.  The drugs had their intended
effect.

"Good boy," Kevin said as he rubbed Jake's fur.  "Good dog."

"I am a good dog," Jake thought.

Kevin smiled, pulled Jake from the tub, and then grabbed a towel hanging on
a clothesline to dry him.

"It is almost lunchtime, Zero," Kevin said.  "Follow me inside, and I will
feed you."

Jake felt his head swimming.  He would not resist any command he was given.
He followed Kevin as the man picked his cigar off a table he had placed it
on and then walked inside the house.  As he opened and held the door open,
Jake crawled in after.
