   Party Animals: 6

   It was the following Wednesday before Jamie found time with Colleen
again.  She was truly struggling with some algebra and her mum suggested
that she ring the boy for help.  Jamie appeared 20 minutes later, looking
like the innocent schoolboy he wasn't.

   "Hi Mrs Walters" he called out as he breezed through the kitchen door.

   "Hello Jamie, Colleen's in the dining room.  Go on through."

   Jamie slipped into the room, pushing the door behind him.  He was
careful not to close it completely though.

   "Hi Jamie" hissed Colleen "Really struggling here"

   She emphasised the "really" and Jamie got the message, tearing his eyes
off the cute girl in school uniform and dragging a chair alongside her so
that he could look at her text book.

   Mathematics was something that Jamie just got.  He looked at the text
book, looked at the girls attempts at solving the equation and instantly
identified where she had gone slightly wrong.

   He pointed out her mistake and spent another 20 minutes going through
questions with her, showing her hints and tips along the way.

   Mrs Walters came in and offered him a drink and then she and her husband
settled in the lounge a few feet away through a pair of open sliding doors.

   "C'mon Colleen" he encouraged "You can do this"

   He watched as she sailed through the next two questions and then as she
started the third his hand slipped onto her knee under the table.

   The girl gasped at the sudden contact and shot him a look.

   "Concentrate on the question Colleen" the boy urged.

   "Do as Jamie says Colleen" her mother shouted from the lounge "no point
in asking for help and then not taking it."

   "Yes mum" the teenage girl replied as Jamie slipped his hand up her
inner thigh taking her skirt with it.

   She grimaced at Jamie and turned back to the algebra.  He didn't take
the hint.

   His hand cupped her mound through the fabric of her panties and his
finger slipped in to press into the protected slit where he rubbed gently.
Colleen wriggled in her seat.

   His hand moved around, under her skirt, to her rear.  He tugged down on
her panties and she turned to glare at him.

   "Lift" he mouthed silently.

   She shook her head.  He nodded vigorously.

   Turning back to her books the girl did lift herself off the seat.  Not
much but enough for the boy to work her underwear down to her thighs.  He
didn't stop there.  Colleen focussed on her parents for any sign that they
might move, or even look, in her direction as the boy forced her panties to
her ankles.  Then, making a show of dropping a pencil, he swept of his
chair to the floor, swiftly tugged her panties off her ankles and resumed
his seat stuffing her panties into his pocket as he did so.

   "Jamie!" she hissed

   He smiled back.

   As the girl failed miserably to concentrate on the next question in the
book, Jamie pulled her skirt back up to her waist and slipped his hand down
between her thighs and onto bare pussy.  She parted her legs for him and he
smiled as he fingered her.

   Half an hour later and the boy said his goodbyes and received many thank
yous.

   Colleen, conscious of her lack of underwear in the proximity of her
parents and decidedly frustrated by the long unfinished fingering thought
quickly.

   "Thanks for the help Jamie" she blurted out "I'll be around when I get
changed with that cd I promised to lend you."

   "oh, ok, if you're sure" he responded as he slipped out of the kitchen
door.

   Colleen quickly raced to her room, changed into a tee shirt and shorts
and grabbed a cd from the rack near her bed.

   She sprinted down the stairs.

   "Won't be long" she called out

   "Make sure you're not" answered her father "School in the morning"

   She slipped out of the kitchen door, up the garden and through the gap
in the hedge.

   Jamie's father was in the garden near the kitchen door.

   "Hi Colleen" he smiled "Jamie said you'd be round soon.  He's in his
room - go on up."

   She smiled her thanks at the man and hurried through the kitchen door,
into the hall and up the stairs.

   Jamie was sat in a small but comfortable arm chair just staring at the
door and waiting.  He smiled when she burst in.

   "Put the cd on" he suggested

   The girl slipped the disc into his music system and pressed the on
button.  Jamie did the rest with the remote.

   "Now" he asked "what did you really want?"

   "Bastard!" she hissed as she undid her shorts "You have to finish what
you start in this life"

   "You sound just like my dad" grinned Jamie as he watched the shorts hit
the floor.

   Colleen was naked underneath.

   "Get your tits out Coll.  Let's see it all." He hissed

   The girl tugged off her tee shirt whilst still moving across the room to
the boy.  She flung her naked body onto his lap and hooked one leg over the
arm of the char.

   "No" he whispered into her ear "I think I'll fuck you instead"

   The girl gurgled something and stood as Jamie stood behind her and
unzipped his jeans.

   He was hard, like iron, and his cock was hot when her fingers trailed
over it.

   He took by the hips, turned her and bent her over that same old armchair
and then, without pretence or delay, he slipped his erection between her
legs and pumped hard.

   Colleen was more than ready and her orgasm swept through her quickly. 
She had to concentrate to hold herself up whilst Jamie slammed into her
from behind.  He didn't take long, filling her with his hot jism and then
slapping her backside as he pulled out.

   He waited until the girl had tugged panties, retrieved from the boys
pocket, and shorts into place before pushing her to her knees and feeding
her his semi erect cock for cleaning.  Then he let her tug her tee shirt
back into place and walked her downstairs thanking her for the loan of the
cd as they passed his mother in the kitchen.

   Colleen darted up the garden and into the gap in the hedge.  There she
dug out a tissue and, undoing her shorts, tried to stem the flow of
translucent goo as it slid down her thigh.

   An hour and a shower later and the sweet smelling pyjama clad girl
kissed her parents before heading off to bed.  She slept soundly.

   On Thursday Daniel asked Jamie if he fancied staying at his place on
Friday night.  He suggested that they needed to do some homework together.

   "Right" said Jamie "That's what you told your folks....  What's really
up?"

   Daniel grinned

   "It's Elaine.  I've been trying to get her alone all week but she's
staying out of the way!"

   "And you think I can help?"

   "Reckon I just need to get her started.  Then I'll be able to fuck her
anytime I want." Mused Daniel

   "Might not be that simple" argued Jamie "Some peeps don't like the idea
of a brother screwing his sister - maybe Elaine isn't happy about it."

   "So what then?  I have pussy in the room next to mine.  I know she loves
cock and I wanna bang her." Squealed the boy just a little too loudly for
Jamie's liking.

   "Shhhhh!" Jamie reprimanded the boy "I'll give it a go but if she
doesn't want to you'll just have to find an alternative source of fun"

   "Jeez Jamie, maybe I can make a move on Colleen then."

   "Colleen" said Jamie fixing his friend with an icy stare "is off limits
except when I say so."

   Still the following evening Jamie found himself sat around the kitchen
table with Daniel and Elaine as the twins' mother served them an early
supper.

   "Have you covered the industrial revolution yet?" asked Jamie as Elaine
caught his eye.

   "What, oh no, a couple of weeks I think." The girl replied

   He had tried the trick before and it had worked then, would it now?

   "Well" he went on a little louder "You might wanna join us for a couple
of hours this evening so you can get a head start."

   Elaine glanced self consciously at her brother who almost drooled but
before she could politely decline her mother interrupted.

   "That would be a great idea.  You know we have these people coming for
dinner so you would have some company as well." She urged

   "I suppose" Elaine replied desperately trying to find a reason not to
join the boys.

   "Great then that's settled" snapped Jamie "We'll finish here and then go
down to the basement."

   An hour later and Elaine was, surprisingly, fully dressed as she sat
alongside Jamie and her brother discussing the start of the industrial
revolution.

   "Excellent!" announced her father who came down the stairs unannounced
"Don't work too hard kids" he admonished "but when you start to play keep
it down as the Johnsons will be here any minute.  Catch you later!" he
finished as he turned away.

   A silence descended over the trio as the boys waited for the sound of
the door closing at the top of the stairs and the cogs clicked into place
in Elaine's mind.

   "Had enough books for now?" asked Jamie

   "Too right" squealed Daniel slamming his text book shut.

   "I might just go to my room" suggested Elaine

   "Have I upset you?" asked Jamie whilst signalling Daniel to stay out of
it.

   "No, no, not at all" the girl stammered "It's just that.....  it's just,
well"

   Jamie silenced her by covering her lips with his own.  She pushed at his
shoulders briefly but then relaxed and kissed him back.  His hands
travelled to her breasts.  She gasped and put her arms about his neck.  One
hand travelled lower, cupping her mound through her jeans and she hasped
once more.

   He broke the kiss.

   "Still wanna go to your room?" he whispered

   "Not really" she admitted.

   "Shirt off?" he queried

   Elaine nodded and Jamie helped her off with her tee shirt.  Daniel moved
in and helped with the bra and then the girl was between them, topless and
unprotected as two hungry boys ravished her breasts.

   She made no objection when Jamie slipped the zipper of her jeans down,
or when he popped the top button and made not one peep when her brother
tugged the denim and her panties, all in one go, down to her ankles.

   Naked now she tried to catch her breath, to slow the excitement and take
back at least a little control.  Jamie slipped a finger into her and her
attempt failed.

   The boys helped her lie down and took up position on either side.  They
toyed with her nipples and fingered her moist passage and she breathed deep
and ragged.

   "Now my little slut muffin" whispered Jamie "Why have you been so nasty
to Daniel?"

   the girl opened her eyes and looked from boy to boy.

   "It's not right!" she hissed "brother and sister fucking.  It's not
right."

   Jamie nodded even as he probed deeper into her cunt.

   "But you were happy to suck him off and get fingered by him"

   "Yeah but not fucking, really, please, please Daniel" she almost sobbed.

   "Daniel will be fine about this" Jamie assured her "You'll just have to
be nice with your lips is all"

   Elaine nodded her agreement enthusiastically.

   "And" Jamie continued "If you need to help to find him a fuck buddy, you
will won't you?"

   She nodded again.

   "You happy with this Dan?" Jamie asked

   "Guess so.  At least my sis sucks cock huh" the boy replied

   "C'mon then" urged Jamie "Up on all fours."

   "Are you gonna......." She half asked

   "I'm gonna fuck you `til you're sore and Daniel's gonna do you at the
other end." "Shit" hissed Elaine

   "Unless you want us to stop now?" added Jamie suddenly stopping all
movement.

   Elaine wriggled to try and keep the contact going and then rolled over
onto her stomach and dragged herself to all fours.

   The boys ignored her for a few seconds.

   "What?" she squealed

   "What do you want us to do?"

   "Huh?"

   "Do you want Daniel to fuck your mouth?"

   "ohhhh goddddd"

   "And should I ram this up your cunt?" asked Jamie wiggling his erection
for her to see.

   The girl parted her legs wider and opened her mouth.

   "Let's do her" suggested Daniel

   That first time was text book.

   The boys managed a good rolling motion and Elaine was impaled like a pig
on a spit.  She felt the ripple of orgasm wash through her well before her
brother fed her his sperm and quite some time before Jamie finally released
his hot jism deep inside the girl.

   The boys retired to the sofa and Elaine crawled between them lapping at
their spent cocks until hardness returned.  Then, without invitation she
clambered onto Jamie's lap and speared herself.  She did all the work that
time, riding the boy hard so that when she finally drenched him with her
juices his erection was red and sore.  Slipping from his lap she crawled
between her brother's legs and slurped his erection into her mouth.  Jamie,
after a short recovery, slipped down behind the girl and fingered her
quietly.  When she was close to orgasm and bucking her hips into his hand
he stopped, clambered back to the sofa and sat.

   Elaine lifted her mouth from her brothers' crotch with pleading in her
eyes.  She stood to clamber back aboard the Jamie spear but he covered
himself with his hands.

   "Too sore" he mouthed

   Elaine looked at Daniel who sat quietly stroking his shaft.

   "Just this once" she whispered

   Daniel grinned and held out his hand to steady her as she climbed onto
his lap.

   He finished quickly, filling his sister with his cum but continued to
thrust into her whilst she dragged a third orgasm out of her tired body.

   "Way cool sis" he hissed as she lay back on the rug, legs parted and
mixed fluid dribbling from her.

   Finally she dressed and made her way up the stairs and to bed via the
shower.  The boys stayed in the basement for a while.

   "See" asked Jamie

   "See what?" asked Daniel

   "Don't push her and you'll get the odd fuck.  Either way you can get
blowjobs whenever."

   "Yeah that is kinda cool" agreed Daniel.

   "Ready for bed?" asked Jamie

   "Be right with you mate, just gonna make sure my sis is ok" grinned
Daniel.

   The end of term came up on the youngsters quickly after that.

   The summer was one of those rare long hot and dry seasons that visit the
UK every 10 years or so and Jamie quickly built up a habit of packing a
light lunch, clambering onto his bike and setting off for the day.  The
first weekend came and with it the first barbeque with Jamie and his
parents being invited around to Colleens' on the Saturday evening.

   Mrs Walters was quick to comment on how Jamie was growing up, how
handsome he was and how brown he was turning.  The boy blushed on cue.

   It was his mother who spoke up for the boy.

   "Well he's been out on that bike almost every day.  Gone at 9 and not
back until four or five o'clock.  Travels miles.  Still better than sitting
on the sofa with playing computer games." Said Mrs Bennett

   "Couldn't agree more" interjected Mike Walters, Colleens' father
"Colleen could do with a bit more exercise to get rid of some of that puppy
fat."

   "DAD!" shrieked Colleen as Jamie struggled to both control his giggles
and remember any significant puppy fat.

   "Oh that's not fair John" scolded his wife "But you could do a little
more exercise young lady" she finished, spreading the retribution evenly.
Colleen glowered at her parents.

   "Whatd'ya say Jamie?" asked John Walters "Would you take her with you on
the occasional ride?"

   Jamie appeared to think it over.

   "Yeah, ok" he finally said "do you have a bike Coll?"

   Her mother answered for her.

   "Well no, not one that fits her properly.  But we could get her one.  I
think it would be good for you Colleen, and nice for you and Jamie to get
to know each other a bit better now that you go to different schools."

   Colleen looked from parent to parent.

   "Well?" snapped her father "Do you want to go for a ride with Jamie or
not?"

   "Yeah, ok" she replied quietly "As long as I won't be in the way."

   That settled the Walters family trooped off early on the Sunday morning
and came back a few hours later with a sparkling new mountain bike,
rucksack and a lycra cycling suit in Red with a helmet to match.

   Jamie almost fell off his bike when he saw Colleen wearing the outfit
the following Monday morning.

   The suit was figure hugging to say the least.  One piece short sleeved
top and shorts that stopped a few inches below the tops of her thighs with
a single zipper running from the base of her shorts to the crew neck of her
collar.

   "Put your tongue away Jamie Bennett" the girl snarled "Where are we
going anyways?"

   Jamie's mind raced.  He had planned on a gentle ride, a long lunch break
and plenty of time with the girl.  Now he wanted to get to the time with
the girl as fast as possible.

   "Follow me" he almost squeaked as he mounted his own bike and set off at
a gentle pace.

   After a while he dropped back and rode alongside the girl for a while.

   "Nice suit" he yelled

   She glared at him with her eyes but the smile playing across her lips
said that she was glad that he had noticed.

   Jamie dropped back just a little further, urging the girl to continue
pedalling, and witnessed the tautness of that bright red lycra stretched
across her firm young buttocks.  Only the outline of her panties spoiled
the view.

   Pulling ahead once more he took a quick left through a bridleway,
slipped from that to a narrower path and emerged at the rear of a large
supermarket.

   Leading Colleen around the front he pulled up outside the main doors and
held out his had to take the bike from the girl.

   "What do we need?" she asked stepping brightly off the bike.

   "We don't actually need anything" the boy grinned "But I'm struggling
with the small details"

   She was clearly puzzled.

   "Go into the ladies and get rid of the bra and panties" he smiled

   "Jamie!" she hissed looking around her.

   "Go on" he urged "they're pretty obvious under that suit."

   Colleen looked at her shoulders and could clearly make out the straps of
her bra.  She looked at the bottom end and, pulling the material taut, she
could also see the outline of her panties.

   She sighed theatrically and, leaving Jamie with bike, bag and helmet,
she trooped inside.  She was back in seconds to collect the bag!

   A few minutes later and she rejoined him, mounted the bike and set off.
He pedalled to catch up, taking the time to admire the new and improved
rear view as he did so.

   By 11.00 his revised itinerary saw the youngsters arrive at a local
reservoir.  There was a bundle of activity around the activity centre and
loads of people using the water for kayaking, wind surfing and the like.

   He led the way around the waters edge on a well worn track.  They passed
by fishermen and family groups out walking and then, on almost the opposite
side of the water from the activity centre, Jamie slipped off the path,
down a gully and around a bend.  Colleen raced to keep up with him.

   When she did find him he had discarded his bike and was opening his
rucksack.

   Colleen took a moment to look about her.

   They were in a man made gully through which one of several water courses
idled through to the reservoir.  Over the years the water had formed a
rounded bottom and what might have been described as a beach.

   The gully was 10 or 12 foot deep and the grasses growing around the edge
added another 2 or 3 foot of privacy.

   "Is it safe?" she asked quietly

   "Probably not in heavy rain" the boy replied "reckon it gets pretty deep
in here before it hits the reservoir proper."

   She stood, hands on hips.

   "That's not quite what I meant" she mumbled

   "Oh, you mean are we likely to be disturbed?"

   Colleen nodded

   "No.  I've been spending hours here some days and I've never had anybody
come close.  I've heard people walking on the path if they've been loud or
had kids with them but that's about it."

   Colleen smiled

   "You come here a lot?"

   "Only this year.  I knew that I'd need to find somewhere"

   "Somewhere for what?" she asked

   "Somewhere to undress you, to play with your tits, to fuck you." He said
casually

   "oh really!" she said with a slight hint of indignation

   Jamie laughed

   "Difficult to play hard to get when your nipples have turned to rock" he
grinned

   Colleen looked down at the giveaway bumps pressing through her suit.

   "I told dad this was too much" she whined

   "Much too much" he agreed moving closer

   His fingers reached out ad took the zipper, lowering it gently and
steadily.

   "Are you sure J?" she asked even as her breath faltered

   "Sure about fucking you?" he replied as the zipper slid past her belly
button

   "Sure we won't get caught!" she hissed as the zipper stopped just above
where her neatly trimmed pubes started

   "Pretty much certain" he whispered as he pushed the material off her
shoulders.

   He bent to take a nipple between his lips, shoving her suit down her
thighs as he did so.

   Gravity didn't quite have enough pull on the clingy garment but, as he
moved his mouth from one nipple to the other, Colleen came to the rescue
and wriggled enough so that the red suit pooled around her ankles.

   He pulled away and held out his hands so that she could step forward and
out of her clothes.

   "Gorgeous!" he hissed as his hand came into contact with her mound and a
finger found a secret place of its own.

   "Ohhhhhhh" the girl managed as her knees buckled and he helped her down
to the warm sandy soil.

   He toyed with her with one hand whilst the other undid his own jeans and
she watched out of one half open eye.  As soon as his jeans slipped down
she parted her legs and he needed no more of an invitation.

   That first time was slightly savage, almost brutal, and she grunted and
gasped her way to orgasm as Jamie throbbed and pumped before finally
releasing his warm persona deep inside of her.

   He tugged his jeans back into place and watched the girl as she
recovered.

   "What?" she asked as she noticed his stare

   "Slut, gorgeous, but a definite slut" he grinned

   "I am no such thing!" she stormed.

   "Really?"

   "Really" she confirmed as she moved to gather her little red suit.

   "No getting dressed Coll" he announced "you can stay like that until we
leave"

   The girl looked at the clump of material in her hand, looked again at
the boy and tossed the clothing to one side.

   "Slut" he hissed

   She giggled.

   They ate, they played, they talked and, of course, they fucked again. 
Pretty soon Jamie announced that it was time to go.

   Almost reluctantly Colleen picked up her lycra suit and slipped back
into it.  Jamie waited for her to finish zipping it up before reminding her
about underwear and laughed at the girl as she was forced to strip naked
again to put on her panties and bra.

   Finally they set off on the trail home.

   For three of the next four days they repeated their outing.  Colleen no
longer wore the tight red suit having convinced her father that it really
wasn't necessary for the kind of leisurely riding that they did.

   The jeans and tee shirt combinations took little extra time to discard
and Colleen found herself developing a decent all over tan as the week
progressed.

   On the Friday they were joined at the reservoir entrance by Daniel and
Elaine.  Jamie led the larger group around the water to the entrance to
their little hideaway which greatly impressed the twins.

   Jamie was a little taken aback when he realised that Colleen was talking
to Elaine rather than removing clothing.

   He went up behind her, wrapped his arms around her and cupped her
breasts through her tee shirt.

   "Shy?" he whispered into her ear.

   He thought that she did blush just a little as she tugged the tee shirt
over her head but she quickly moved on to unbuttoning her jeans and he
turned his gaze to Elaine.

   Elaine delayed until Colleen tossed her bra to one side but she too
started to remove her clothing without further coercion.

   The first game was a straight forward orgasm race.

   The girls lay side by side as Jamie probed Colleen and Daniel focussed
on his sister to see who could drag out the quickest orgasm of the day. 
Jamie won easily.

   "Practise" he offered by way of explanation "I do her every day"

   "Jamie!" squealed Colleen

   "Well I do don't I?" he responded

   The girl nodded slightly and blushed furiously.

   "What about you two?" Colleen asked of Elaine as she got her breath back

   "Few times a week" the darker girl admitted "Just fingers of course" she
added

   " I do her mouth generally" Daniel added gruffly

   His sister blushed furiously.

   "We need another girl in the group" suggested Jamie into the slightly
awkward silence "Any ideas girls?"

   "Another girl?  What about more boys?" countered Colleen

   "trust me" offered Jamie "I can get as many boys as you want - all I
have to do is promise to let them between your legs"

   The girl fell silent for a moment.

   "Kristen might be up for a bit of fun" she finally decided

   "Kristen?"

   "Yeah she was at my party, loved it that night, not sure how she'd cope
in company though."

   Jamie smiled.

   "You organise for Kristen to join us on a bike ride next week and I'll
sort some boys."

   "I'm in" hollered Daniel

   Jamie grinned

   "Now then girls" he smiled at the naked teenagers "how about you two
have a race" he said as he unzipped his jeans.

   Daniel was alongside him in seconds, jeans and boxers around his knees,
erection bobbing in the breeze.

   Colleen looked at Elaine

   "You wanna?" Colleen asked

   Elaine bit her lip

   "Always" she hissed

   Keeping to their usual partners the race began.

   This time Elaine won, swallowing as much of her brother's seed as she
possibly could in the process.

   "Keep going Coll" urged Jamie "maybe you need a bit of help"

   He signalled to Daniel who grinned and moved behind the pretty blond. 
Soon two of his fingers were pumping into her and she was gurgling around
the cock in her mouth.  Finally Jamie held her head in place whilst he fed
her and the girl was allowed to slump to one side where Daniel finished her
off with his fingers.

   They ate lunch quietly but with the boys constantly eying their naked
companions.

   When food was finished and there had been some time for digestion to at
least start to do its thing, Jamie stood and slipped out of jeans and
boxers in one go.  His cock was limp and dangled between his legs like the
sleeping animal that it was.

   He grinned at each of the girls in turn before fixing on Elaine.

   "Crawl over here and make it live" he whispered.

   Elaine licked her lips without thinking and then did just as she was
asked.  She crawled the short distance, lowered her head into his lap and
slurped his cock into her mouth.

   She was awestruck at the change of texture, temperature and size at it
grew within her cheek and gurgled her pleasure when the boy reached around
to fondle her breast.

   Colleen watched in fascination as her friend fed on the cock that had
been hers for so long.  She noticed the beads of sweat in the small of
Elaine's curved back and, as the cocksucking girl continued with her task
and her legs parted of their own volition, Colleen noticed the moisture
leaking from her sex.

   She barely acknowledged Daniel when he slipped alongside her and
replaced her own hand with his between her legs.  She didn't complain.  She
complained even less when his head bent to lick and slurp at her breast
whilst his fingers probed her and when, finally, he pushed her backwards,
she lay back, legs wide apart, and waited patiently whilst he clambered
between her legs.

   Jamie waited for the rhythmic thrusting of Daniel's buttocks to steady
before pulling Elaine up from his own crotch.

   Her eyes were hooded and saliva mixed with pre cum dribbled from the
corner of her mouth.  He smiled at her and turned her around so that she
could watch her brother fucking Colleen.

   "Part your legs" he hissed

   Elaine parted her legs and was rewarded with the rod of steel, which she
had crafted in her own mouth, slipping into her.

   The girls were allowed to dress after that.  The foursome made their way
to the reservoir entrance and then went their separate ways to await the
initiation of Kristen.
   End of Part 6
