Summary
     The final instalment of Weasley Sexcapades. A back story. Written in
     snapshots, throughout Arthur's life. From his childhood to his
     training to become the next Alpha.
...Where It All Began...
Arthur had a good childhood. His dad was a well built, strong, burly and stern
man, but kind and gentle when the need arose. Like, when Arthur was five and
had been out playing in the Burrow's garden, and he had had a little accident,
Septimus has run out and found the boy hunched over by the tall elm tree by the
pound. He had sensed the boy's discomfort and misery.
Arthur's back was to him when he got there. Septimus placed his large hands
upon Arthur's shoulders and turned him around to face him. Arthur had wet
himself, simply because he had been having so much fun flinging the Gnomes
around, that he had been laughing so hard he hadn't noticed until it was too
late.
Septimus had been kind and gentle then. He took the sobbing boy back up to the
house and into the bathroom, where he ran a bath and stripped Arthur of his wet
clothes and helped him climb in. Once he had dried off and put fresh clothes
on, Septimus had taken Arthur back to his room and sat him down on the bed and
told him that it was an accident and that there was no need to be embarrassed.
There were other times when Arthur had had a nightmare and had run to daddy's
bedroom and crawled into bed with him. Septimus had woken up to a shuffling
next to him and found Arthur cuddled up, his arms tightly wound around his
daddy's right arm. Septimus had bent his head, kissed the boy's head and fell
asleep, with his own arms wrapped securely around his boy.
In the morning, Septimus had asked what the dream had been about and after
easing Arthur's worries, they both got dressed and ready for the day. As well
as being a kind and gentle man and father, there were also times when Septimus
was stern and brutal with it.
Because Arthur was an only child, he didn't get spanked that often, but when he
did, it was awful. One day a year before he was due to start Hogwarts, Arthur
had been in a snit for most of the day. Which was unusual for him, as Arthur
rarely misbehaved. He had obviously woken up on the wrong side of his bed that
morning, as he was angry and moody all day.
He hadn't done anything his dad had asked him to do, which made Septimus angry.
Septimus' anger came to a head that evening when Arthur refused to go to bed on
time. Septimus finally snapped and hauled Arthur roughly to his feet and after
sitting down on the edge of the boy's bed, he stripped and bent Arthur over his
knee and spanked him.
Fifty firm and heavy swats with his hand and fifty with a switch. Arthur had
screamed, cried and howled throughout his brutal punishment. And once his dad
had finished, the man simple threw the boy aside and onto his bed, stood up,
shouted in Arthur's face to go to sleep and left the room...

...A Lesson in Weasley Law & Fingering A Tight Little Hole...
..Arthur grew into a fine strong, well built and burly man. An exact replica of
his father. On his seventeenth birthday, Arthur was given a lesson on Weasley
Law. Well, it wasn't so much of a lesson per say, more a 'Sit down, shut up and
listen to your Elder' sort of thing.
So Arthur sat down next to his father on his bed and listened to all that
Septimus had to say on Weasley Law. The incest, the creature status, the sex,
the spankings, the roughness, the brutality of it all. The death of one Alpha,
and passing the Alpha gene on to the next in line, etc, etc...
Once Septimus had finished, Arthur found himself naked and aroused and his face
pressed into the mattress of his bed, along with his shoulders, while on his
knees with his arse in the air. Septimus spread the boy's arse cheeks apart and
inspected the smooth hairless crack with his tightly furled pink entrance.
Arthur shuddered as he felt his dad's breath ghost over his tiny quivering
hole.
Septimus slapped Arthur's arse cheeks hard a few times, eliciting loud wanton
moans from the boy, while Arthur's large cock hardened even more, as he felt
his dad grab hold of his heavy low hanging bull balls in his large fist and
pulled sharply on them.
Arthur whimpered, as his dad began to fondle him roughly.
After a short while, Septimus took his right hand and ran two of his thick
fingers up and down the boy's exposed hole. Arthur moaned continuously as his
dad played with him. It ended with Arthur shrieking in pain, his back arched
upwards as he felt something blunt stab sharply into him.
Septimus had shoved two of his thick dry fingers deeply into the boy's dry hole
and not being gentle at all, he began a rough examination of Arthur's internal
structure - making sure to keep his fingers from hitting the boy's prostate.
This wasn't for the boy's pleasure, that was for later that night.
Septimus pulled his fingers free of that tight heat and sucked them clean,
before he gave Arthur a harsh spanking and left his son's bedroom, leaving a
sobbing Arthur lying curled up on his side facing the wall, while his whole
body shivered and shuddered in anticipation of what was due to come...

...Taking Daddy's Load...
..Later that same night, Septimus came into his son's bedroom and hauled him
out with him, along the landing and into his own room. He banished all of
Arthur's clothes and pushed him down on to the floor. The boy knelt there and
waited.
Septimus banished his own clothes and Arthur's eyes went wide and his mouth
fell open at the sight of his burly muscled father, standing naked before him
with his hard, thick monstrous cock (much thicker and longer than his own large
cock and balls) with his even bigger, low hanging bull balls.
Septimus stepped closer to the boy and grabbed a tight and painful hold on to
his son's hair, yanking Arthur's open mouth forward and onto his monstrous
colossal cock. Arthur moaned around it, as his dad thrust deep into his already
aching hot wet mouth, ramming past his gag reflex without any warning, making
Arthur choke and gag as he felt the cock slide down into his tight throat.
Arthur's nose got crushed into his dad's smooth abdomen, his chin was nestled
against the man's hairless balls. Septimus looked down into his son's face, as
he kept Arthur's face flush against his pelvis.
'Eyes up!' Septimus commanded with a growl.
Arthur looked up at his dad with lust filled eyes, breathing hard through his
nose. Drool and spit leaking from around the cock in his mouth and his bruised
lips. Smiling nastily, Septimus pulled his hips back and pulled out of his
son's mouth completely.
Arthur coughed and spluttered as he gasped in deep breaths of air, while
Septimus hauled him up and threw him on to the bed on his back, knocking the
wind out of the boy.

Soon Arthur found himself bound to the bed. His wrists had been spread above
his head and tied to the head rail, while his Legs had also been spread as wide
apart as they could go and hung suspended from the ceiling by invisible rope.
Arthur looked up at his dad, and found his father's eyes had turned jet black.
He found himself mewling as his dad gazed at him with a feral predatory look on
his stern face.
Arthur felt his tiny tight exposed hole quiver in anticipation, and mewled
again wantonly, his own large and hard hairless cock oozing pre cum over his
smooth abdomen. Septimus shuffled forwards until his knees were pressed firmly
against Arthur's inner thighs and his colossal monster was poised against his
boy's tightly furled entrance.
Septimus slammed his dry cock brutally hard and fast in one quick thrust deep
into the boy, making him cry out in agony at being so brutally taken with no
preparation and bone dry. Arthur continued to howl and scream in pain, until
Septimus nailed his prostate dead on.
It wasn't long after that, that Arthur began to see stars. Soon the pain
quickly turned into extreme pleasure, and he began screaming for more and to be
taken harder, faster and deeper. Smiling his predatory smile, Septimus
continued his brutal assault on his son's extremely tight hole. He leant
forwards and clamped his large hands around Arthur's chest and pressed down
hard, as his thrusts became more wild and animalistic.
Arthur's screams of pleasure soon became hoarse as he shrieked and came hard
all over his chest in great warm white globules. Feeling his son's tight
internal walls clamp down even more tightly around him, Septimus gave ten more
brutally deep thrusts and came balls deep inside Arthur's hole.
Arthur felt his dad's boiling hot cum fill him up and mewled brokenly at the
feeling. He lay back and relaxed, as he began to feel his dad pull out. He
broke into sobs, when he felt his dad slam hard back into him again. His abused
aching hole was already overly sensitised.
Arthur felt his eyes sting, as he felt something even bigger enter pass his
overly stretched ring and seated itself deeply inside him.
His dad's knot! He burst into a fresh bout of tears at the pain the knot
brought on. He was stretched now to near breaking point. Arthur whimpered
brokenly once more.

With his knot firmly in place, Septimus pulled back. His overly large knot
plugging Arthur's absolutely wrecked and gaping hole, making the boy moan
again. Septimus plunged in going deeper than ever into the boy's gut, making
Arthur cry out, his throat raw from screaming in pain.
Septimus growled again as he continued to plough deeper still into his boy.
Arthur continued screaming hoarsely, as his sensitive cock hardened again and
oozed more pre cum. Arthur wasn't sure if he could take a double knotting.
'It hurts Daddy!'
'Cum again for me, Boy! Cum NOW!!'
Arthur screamed and came harder than he had a few minutes ago. He passed out,
as he felt his dad's knot stretch out his abused internal walls even more.
Septimus continued to drill hard into his unconscious son's exhausted and limp
body, until he came hard again...

...End of an Era...
..Arthur climbed on to his daddy, straddling his dad's waist and sank down on
to the man's large solid cock. He threw his head back and moaning loudly as he
slid further down, squirming, as he felt it stretch out his tight internal
walls. Once he was impaled balls deep, Septimus gripped his son's hips and
raised him up until his thick bell end was all that was left plugging his boy's
hole. Arthur was mewling and moaning, as the ring around his strained cock
tightened itself to its limit.
Snarling, Septimus thrust harshly upward as he pulled Arthur down with
considerable force on to him, making his cock slam in with harsh brutality
splitting the boy's insides wide apart. Arthur howled at being taken so
ferociously. Tears streamed down his face as he felt that colossal cock deep
inside him, pummelling deep into his gut.
Soon Arthur was pounding away of his own accord without his dad's help and rode
his daddy's monster like a pro whore, his arms wrapped loosely around his
father's neck for extra leverage. Arthur was bouncing up and down, riding his
dad's cock at such a speed, as he screamed and shrieked with want and desperate
need for release. After another thirty minutes, he felt the cock ring fall
away.
Arthur screeched as his purple cock began to flex in between himself and his
dad's chest, as he continued his brutal bouncing, riding out his painful
orgasm. He came long and hard all over his dad's upper body. His tight internal
walls clamped down on the cock inside him, making Septimus cum hard.
Immediately followed by his large knot.
Arthur gave a hoarse shriek as he felt his insides expand even more with the
knot. As soon as he had knotted his son for the last time, Septimus faded away
with a smile - leaving Arthur alone and on his own in the world. Arthur groaned
as he fell backwards on to the bed and simply lay there, until sleep claimed
him...

...New Beginnings...
..Several years later, Arthur found the surrogate to impregnate. Molly Prewett.
He remembered her from his time at Hogwarts, she was a bitchy woman. He cast a
love potion from a distance into her. There was no way he would willing sleep
with the bint. He made sure that they acted like the perfect couple, though he
only fucked the woman after casting a heavy glamour charm upon her.
He turned her into an exact replica of himself, a doppelgänger, and set about
fucking himself/Molly until he had impregnated him/her. For seven years he
fucked Molly as himself and each year, she/he gave birth. Once Ron had come
along, he removed the glamour charm and love potion and killed her. He couldn't
risk her staying alive.
After the final battle with Voldemort, Arthur adopted Harry Potter into the
family, and when they found out that Draco was all alone after the Death Eater
trials, Arthur adopted him too. He was now looking forward to his own
Prerogative as Alpha.
