-Two years later on Sammy’s sixth birthday-

Sammy walks to his door after shopping with his mommy, he opens
the door-

“SURPRISE!!!!” The whole room fills with the sound of people
yelling and cheering.

Sammy is taken back and for a second he doesn’t know what to do.
But soon he gets exited and runs into the crowd and gives
everyone a hug, thanking them for coming...

The party continues and they all walk to the backyard where there
are pony rides. Sammy gets excited and asks for a ride.

The man straps the boy on to a wooden horse and lubes up his ass
and then guides the pony’s cock into the birthday boy’s ass. The
pony get’s excited and beings to fuck Sammy hard, the boy smiles
for the picture. His mommy, daddy and grandpa are so proud that
can take the pony’s cock.

“He is such a slut.” His mommy says in a proud tone.

“I know, I’m so proud...” His daddy says, “I wasn’t able to take
a pony at that age.” Charles remember.

“That was true but you still had the finest ass in town.” Albert
said slapping his son’s ass.

After playing with his friends, games like “Stick the dick in the
birth day boy” where parents or kids (that have a penis 6 inch or
larger) are guided into the birthday boy’s ass... It’s harder
than it sounds but whoever wins gets to cum in the birthday boy
ass.

After cake the presents came out... A lot of people bought him
clothes but someone got him the home version of Daddy’s Ride...
Some other people got him anal toys.

“Ok this is from us,” his mommy, daddy and grandpa said as they
pulled out a slim envelop.

Sammy opened it thinking it was a card or money but instead it
was as note that read “we got dogs for the whole family.”

About six months ago Sammy was watching tv and saw a show called
my three dogs, where a mommy, daddy and son owned three dogs...
And in the show they always ended with them getting  fucked by
the three dogs.

His daddy said he had a dog that that fucked him when he was
little and grandpa still had his dog, butch.

As Sammy read the letter mommy and daddy brought out three dogs
and Butch.

“Their names are Rusty (brown great dane), Bernie (bernese
mountain dog) and Rock (Bull Mastiff).” said Charles “and you
already know Butch (Mastiff), They’re already trained.”

Sammy’s eyes widened as he saw the big dogs. “I want Rusty.” Said
the boy

“We knew you’d say that.” His mom and dad said at the same time.

The boy bent over and called over Rusty, The dog responded and
positioned itself behind the boy... Soon it began humping as it
mounted him. The slimy cock found it’s mark after a couple of
tries, and soon the boy was balls deep in doggy cock.

His parents and grandpa followed suit bending over and taking
their doggy’s cock. Sammy’s mommy took on Bernie, his daddy took
Rock’s thick cock, and Albert took his own Butch’s cock...
Everyone cheered as they watched the family’s bestiality session
some of them wished they brought their own dogs but instead they
fucked each other... Soon there was an orgy of incestuous sex
everywhere.

Sammy was enjoying his new pet’s cock he felt the doggy’s sperm
leaking out and suddenly he felt a bump the seemed to get larger
with every thrust... He knew what it was, the knot... This
excited the boy, so he bucked as the dog pushed forward and soon
the knot was stuck in him.

“I did it.” The boy said as he felt the large knot “It’s getting
bigger!” the boy screamed excitedly.

The knot was getting bigger and bigger and soon it was stuck the
feeling of warm puppies inside him made him cum hard as Rusty
tried to pull out in vain, instead he just managed to turn
himself around.

Sammy noticed his mommy, daddy and grandpa were in the same
situation. He looked a them, his grandpa was still cumming from
his doggy and you could see the puddles his mommy and daddy had
in front of them.

“I love you,” He said as he came again from Rusty moving.

The end
