   The Advent Calendar Door 15
   Typed 06/12/2018
   OPENING DOOR #15
   Not waiting for an answer Pete walked back to the Advent Calendar, with
his mom was behind him as he prised little door number fifteen open.
   Taking out the envelope he opened it quickly, took out the type written
card and read out *Pete!  Today is double pleasure day for you!  Have your
mom take you to the playground, you will wander about naked, and the first
two girls you see you will approach and ask her and her mom if she is with
her if you can fuck her (Do not fret as no experience is necessary, as it
will come naturally for you and the girl to enjoy)* **Take this card with
you**
   Smiling at his Mom Pete said "Wow, I am going to get to use my cock and
fuck someone!  I do hope I enjoy it as much as people do who have fucked
me!"
   Janice smiled and said "Make the most of it Pete let's hope there are
some sexy girls there!"
   They set off for the playground, it was still bitter cold out but Pete
walked around the playground naked without a worry, there were a few dog
walkers there looking at him and smiling at him as his hard cock seemed to
lead the way, on the second circuit of the playground Pete heard a child's
voice over on the swings, he turned towards the voice that he thought he
recognised and indeed see that he had met this little girl once before in
this park and had been to her house to ask her to wank him off till his
balls were empty.
   Now she was sitting on the swing with her Granny pushing her gently,
both keeping an eye on his as he approached, as he went up on the swing
Pete could see she wasn't wearing panties making his cock throb even more.
   When he was close enough he smiled at her and said "Hello again!  Can I
fuck you till you are satisfied?"
   The eight year old girl looked up at her smiling granny who nodded,
before she turned back to Pete nodded and said "My bum or my cunny?"
   Pete smiled and said "Both I guess!"
   The girl said "In that case yes you can fuck me!  Do my cunny first, and
then as I do like to take it up the bum like a boy, do me up my bum and
spunk up there!"
   She got off the swing undressed infront of Pete, he couldn't help but
stare at her cunny as she faced him, making his cock twitch with
excitement, then she positioned herself on the swing with her legs spread
open and waiting for him.
   Pete easily buried his fat six inch cock up inside her cunny, something
he obviously hadn't experienced before blowing his mind as his cock went
inside her tight little cunny, making her moan and groan with obvious
pleasure, increasing her pleasure tenfold as he pounded into her, he too
felt awesome moaning out how good she felt being inside her.
   He was lost in the pleasure he was having, then happened to look up and
see a crowd had gathered to watch him fuck the eight year old on the swing,
it seemed their bodies were in tune with each other once he was inside her
and he knew how to please her without getting the urge to shoot too early.
   He fucked her, he made love to her, he pounded into her, giving her as
much pleasure as he could with her voicing loudly just how good he was,
they had been at it for forty to fifty minutes before he felt the first
tingle of wanting to shoot, he told her he was close so she said "Take it
out and do my arse!"
   Pete withdrew so she could change position and with the help of her
granny she presented her arse to him while still on the swing, he entered
her as gently as he could and finally buried himself ball deep inside the
even tighter hole of her arse and started to fuck her, she looked up at him
smiled and moaned "That's feels so much better doesn't it Pete?"
   Pete looked down smiled at her and just nodded as he fucked her up her
arse, while he glanced down at her red puffy cunny and watched his cock
disappear time and time again into her tight arsehole further down.
   It was some ten minutes before he blasted his spunk into her bowels,
giving him the best orgasm to date, his cock only semi deflated afterwards,
but let it slip from the warmth of her arse, feeling the coldness of the
day around the exposed head of his cock once it had fully exited!
   Pete stood there looking down at the little girl, she was smiling up at
him as she watched his eyes wander from her cunny to her arse as she
thought he was so damn good, she will have him again in both holes.
   After what must have been less than a few minutes Pete happened to look
up at the crowd that had gathered to watch him fuck the eight year old girl
he looked straight into the eyes of the girl he sat next to in his class
that fancied him and had paddled him a few days ago.
   She had made her way to the front so was in talking distance when Pete
looked directly at her and said "Can I fuck you?"
   She smiled and said "Yeah just my cunt!"
   Totally unashamedly she stripped off out there in the cold and like the
other little girl she sat on the other swing seat, opened her legs to
expose her moist wet smooth cunt and beckoned Pete into fuck her even
though she was still a virgin she had wanted Pete to be her first.
   So once again Pete went into action, knowing instinctively how to treat
this girl for her first time, he wanted to make it as pleasurable as he
could, something he did, entering her gently and once he was fully inside
her she coo-ed with pleasure, he went from gentle strokes to hard full on
pounding of her cunt all done in tune with her bodies needs bringing her
off multiply times in the process, making her first experience something
extra special.
   One would have thought that at the age of twelve, totally naked and
being fucked in the kids playground on a cold December morning infront of a
crowd of strangers would be something special in its self, but being given
multiple orgasms by another twelve year old seemed to do it.
   Some fifty minutes they were at it, Pete never tiring of fucking his
class mate, he knew it should take longer for him to spunk the second time
but this seemed never ending; he looked down at her and said "You tired
yet?"
   She smiled as she said "OH no!  You keep ploughing me; it is the best
feeling in the world!"
   Perhaps twenty minutes later he finally felt his balls ready to shoot,
he buried his cock in as far as he possibly could get it inside her and
shot his spunk deep inside, making her orgasm at the same time and feeling
utterly contented.
   When he withdrew from her cunt his cock was still semi hard and his
balls had this tingling feeling in them, the other little girl got his
attention, she smiled at him and said "My turn again!"
   Almost before she finished speaking his cock was as hard as it had ever
been, and he was ready to go, giving her a repeat performance of earlier
climaxing in shooting another load of spunk into her bowels after using her
cunny!
   When he was done his class mate came over kissed him on the lips and
said cryptically "You owe me a fuck Pete!  I have to go now, thanks it was
a real pleasure!"
   The grandma helped the little girl off the swing; she stood up, looked
up at Pete and said "Thanks you were awesome!  We have to go too!"
   The rest of the crowd had dispersed now the sex show was over, leaving
Pete and his mom alone.  Janice looked at her watch and see it was only
twelve thirty, she put her hand in her coat pocket and found the card Pete
had given her before they left; she bought it out, turned it over and
quickly read out *Pete!  You have given girls a try!  Don't leave the park
till dark as it now time to try some sexy boys bums!  Ask the first two
boys mom's that enter the playground if you can bum-fuck their little boy*
   By the time Janice had finished reading from the card a group of about
twenty people had started to arrive in the playground, leading the way was
a girl with a little boy known to Pete as Damon, for Pete this little five
year old had some sweet wee and a perfect little bum.
   When Damon see Pete he dragged his mom over both reaching them before
the others did.  Pete greeted them and said to Damon's mom "Can I bum-fuck
Damon?"
   She looked from his rampant hard six odd inch cock back up to his face
and said "If you can get that up him then bum-fuck him!"
   She helped Damon out of his clothes, his little cocklet sticking out all
excitedly as he was draped over the seat of the swing to present his small
pert bum to Pete.
   Pete wasted no time in dropping to his knees to eat the little tyke out
much to Damon's delight!  Now that Pete had feasted on his little arsehole
he lubricated it, slipping his index finger in with relative ease to get
some slickness inside without too much protest from Damon, then he
lubricated his cock before he presented it to Damon's virgin slick hole and
pushed the head of his cock into the tight sphincter of the five year old,
who only grunted as he was invaded, before Pete knew it he was ball deep
inside the tyke, with Damon seemingly moaning with utter pleasure from
having something so big stuffed up his tight little arse.
   Damon's mom had orgasmed twice just from watching Pete's fat cock slide
ball deep into her son's tight little arsehole without any real complaint
from Damon other than he felt real full in his botty as it was so much
bigger than mommy's finger she put up there!
   Now Pete was inside Damon, and Damon had got used to having his bum
stuffed so full; and like the eight year old girl Pete felt even more at
home and in tune with Damon's small tender body as his tight anal passage
sheathed his cock to perfection.  Not rushing at all he made love to the
tyke with long deep strokes going in and out constantly making the little
boy buck and moan as his insides were rearranged by his cock.
   After about half an hour Pete was able to exit and re-enter the little
boys arsehole time and time again, going in ball deep each and every time
with Damon's mom watching closely and encouraging both Pete and Damon to
"Get it on!" and "Go for it!" "Breed the little fucker!" It seemed the
encouragement worked as Pete power fucked the little tyke much to Damon and
his mom's delight as he whimpered and she orgasmed yet again and said "I
knew you would love it up your tight little arse!"
   Finally Pete worked up the urge to shoot his spunk into the little
tyke's tight little bum, holding onto his slim waist he buried himself as
deep inside his arse as he could possibly get and pumped spurt after spurt
of hot boiling spunk into the tight confines of the little boys bowels.
   Much to Pete's surprise he shot more spunk into this little boy than he
had ever shot before, making him think at one point he wasn't going to stop
shooting.  Finally when he was done he slipped his still hard but sensitive
cock out of the little tyke's delightful arsehole, and watched rivers of
his cum flood out of the open arse and run down over his little ball sac
and down the insides of the little boys sexy smooth thighs.
   As Pete looked up Damon's mom was smiling at him and said "You did him
good!  You are a natural bum fucker!"
   Damon eventually got up off the swing turned and faced Pete; he smiled a
tear stained smile and said "You going to do that again another time?"
   Pete said "You bet, but not today OK little fella!"
   Damon hugged Pete and said "See you next time!"
   As the crowd dispersed to let Damon and his family exit, standing there
where the crowd had parted was the eight year old boy with his mom who had
given Pete his first full bladder of wee.  Pete beckoned the boy towards
him, with his mom in tow, when both were close enough Pete asked the boy's
mom if he could bum-fuck her son?"
   She nodded and said "Let me watch him empty himself into your mouth
first then his bum is all yours!"
   Pete found himself licking his lips at the thought of drinking his wee
again as the boys mom helped him get undressed, Pete was on his knees as
the boys mom held her son's arms up giving better access to his cock for
Pete to put into his mouth and savour the sweet urine of this adorable
little boy.
   Urine consumed, his cock stimulated inside Pete's mouth so when Pete
pulled off is was sticking out rock solid, wasting no time the boy turned
and adopted the same position as the little tyke had and presented his
gorgeous soft arse to Pete, Pete couldn't resist and dived in with his
tongue and ate him out enjoying his taste and the feel of his bum cheeks on
his own face cheeks, sending Pete insane with desire for this little boys
arse.
   After thoroughly eating him out, then lubricated Pete presented his
throbbing hard cock to the boy's tight anal passage and slipped it in,
making the boy yelp in the process.
   Now Pete was inside, even just the head of his cock, Pete felt the boy's
demeanour change, becoming more wanting, more needing, Pete instinctively
knew what to do, he held the boy by his slim waist and applied steady
pressure with his cock and pushed it home in one long push till he was
buried all the way home, ignoring the protests from the boy that it hurt,
but once it was all the way inside him he moaned "OMG that feels great! 
Take it out and shove it all the way in!  Make my arse scream in pain!"
   So without another thought Pete did exactly that, he withdrew and shoved
his cock back in to the hilt, feeling the boy tense up under him but only
moan "How good it felt!"
   Pete looked up and into the eyes of the boys mom, she was smiling at him
as she watched him bum-fuck her little boy, finally saying after a few
minutes of constant fucking "Give him what he deserves and desires, a good
old fashion shafting, nothing more, nothing less, just someone to use his
tight little arsehole to make it hurt where he wants it to hurt the most!"
   Pete smiled and said "He is amazing, it feels so good being inside him,
his bum is a dream to look at and even better to bum-fuck!"
   This coupling of an eight year old boy and twelve year old boy in the
playground had attracted a large crowd all cheering them on with Pete
pounding him harder and harder as and when the crowd demanded it, he never
tired and the boys arsehole seemed to eat his cock wanting more and more,
as the harder he did it the more the boy responded with pleasurable moans.
   Finally after over a hour and a half Pete felt his balls tell him they
needed release, Pete slowed down to a nice steady fucking pace, enjoying
the sensation of moving his cock in and out of the boys arse and feeling
his bum with his hands finally got Pete to release his built up spunk and
fired volley after volley into the warmth of this boys guts, six, seven
eight powerful volleys erupted from his cock into the boy, when he finished
he stayed hard, and the boy started to move the swing so he was moving
inside the boy once again, even more slick as the spunk acted as a super
silky smooth lubricant, stimulating him and he found himself stroking the
boys smooth thighs before holding his slim hips as he started to fuck him
yet again, the boy was saying "Yes, yes do it, get it right up me, make my
arse into a pussy with big pussy lips back there!"
   Pete found himself in what he considered as heaven, deep inside the arse
of a little boy, who wanted it done to him hard and wanted Pete to
basically ruin his shitter and make him a pussy boy!"
   Pete took up the challenge and bum-fucked him like before, entering and
re-entering his tight little arsehole, making the entrance puffy just like
the lips of a girl's cunt were.
   After about an hour or more of intense bum-fucking, entering and
withdrawing, Pete totally withdrew spread the boys bum cheeks further apart
to look at his handiwork and whistled when he see just how much the boys
arsehole now looked like the lips of a little girls sweet cunny do!
   The boys' mom looked, smiled and said "Nearly there sweetheart, keep on
banging him till I have a proper pussy boy!  Now you just bang the arse off
him, once he has a proper boy pussy he is yours whenever you want him!"
   A rather excited Pete went back to bum-fucking the boy, giving him a
good pounding, making those much desired pussy lips for him and his mom and
eventually filled his bowels up with eight more spurts of spunk.  Finally
both boys were satisfied.  The boy's mom was more than satisfied when she
see just how much her son's pussy lips hung outside all red and puffy. 
Pete stood up to see all the smiling faces of the crowd that applauded him
as they had watched him bum-fuck the eight year old.
   Once Pete was out of the boy's arsehole and the boy stood up awkwardly,
he was cheered by the crowd as his cock stuck out rock solid and his new
boy pussy leaked spunk that started to run down his sexy smooth thighs.
   This time Janice wasted no time she stepped forward took hold of the
little boy bent him over the swing, got on her hands and knees and licked
the spunk from his inner thighs before lapping the rest from his leaking
boy pussy as it oozed out, some twenty minutes later he was clean, Janice
was contented that none of Pete's spunk had been wasted, so she stood up
looked at the boy's mom and said "Couldn't resist his bum!"
   Second show over everyone dispersed after names and numbers exchanged
for the little boy's mom, with a firm promise that Pete will come and visit
very soon.
   One very tired and contented Pete arrived home, showered to clean up and
warm up ready to settle in for the evening, as he passed the Advent
Calendar he see that the picture was pretty much the same as it had been
for a few days now, other than that the little boy in the background looked
naked.
   That night Pete's dreams were dominated by the events of the day, he
relived the fucking of the two little girls especially the bum-fucking of
the first girl, then his dreams turned to both the boys he had bum-fucked,
liking the little tyke, but realising he loved the eight year olds body
more as it was more appealing to him to look at and touch, of course
bum-fucking the five year old was excellent as he was much tighter, but
then again he felt more natural up the eight year olds equally tight boy
pussy!
   In the morning he told his mom about his dreams and she concluded that
he liked bum especially little boy's bums more than girls cunts and told
him not to worry about it.
   Once breakfast was out of the way and everything cleaned away they went
to the Advent Calendar to open door sixteen.
   Both seeing immediately that in the picture standing there naked next to
Pete's mom was the eight year old boy he had bum-fucked yesterday in the
playground, you could see Pete's mom's had her hand on the little boy's
bum, the little boy was now holding out a gift for Pete and smiling.
