 The game had come to an end and the guys were all pumped up.  Their team
had snatched victory from a draw, striking a goal in the 89th minute to
beat their main rivals in the league.  They jumped up and high-fived each
other while the girls watched and rolled their eyes.  Jemma leaned over to
Ceri and placed a hand on her knee.  "It's almost like they'd won the game
themselves!" She laughed.  Ceri smiled and nodded.  To be honest she really
like football herself and enjoyed watching it.  Not just for the twenty two
fit young men running around the pitch (though that helped).  It was also a
game of skill and luck, and not a little heartbreak.  She smiled to see her
dad having such a good time.  It struck her how much his face in happiness
looked like his face in orgasm.  Thinking about the other day made her get
all wet again.  She loved her brother and had enjoyed giving him a blowjob
but being split in twain by her father's dong had really been the highlight
of her life so far.  She wanted more.

   They had all been drinking lager and sure enough Joe and Kenny quickly
disappeared off to the bathrooms to relieve themselves.  Ceri was glad that
there were two bathrooms in the house - one upstairs and one downstairs. 
Thinking that now the game was over she should catch up on some homework
she called goodnight to everyone and headed upstairs.  Being honest with
herself she knew it was not just for some homework but also a little light
relief.  She had to stop thinking of her own dad and brother like this!  It
was improper.

   As she reached the top of the stairs she headed for her room.  This lead
her past the bathroom and she was shocked to see that the door was standing
wide open.  She could hear the sound of someone peeing from inside and
stopped.  Her first reaction was to creep past modestly and go to her room.
Her second was to peek around the door and see if it was Kenny or Joe who
was peeing.  She really fancied seeing her brother's cock again.  And sure
it wouldn't be bad to see Kenny's.  The lad was cute enought.  Seventeen
years old, same age as herself.  Built heavier than his dad but lighter
than his mom.  Dark hair and eyes, and the same naughty grin that his
mother got.  He could be rather sweet too.  Ceri would have said yes to him
if he asked her out.  If only to find out his deeper thoughts.  He was a
very quiet lad really.  Slightly geeky, but then she'd never had a problem
with that.

   Standing here was not getting her anywhere, so Ceri decided to peek. 
Sure enough it was Joe.  He had finished pissing but still had his dick
out, and when his sister saw it her mouth watered.  She was so horny right
now and his dick was a very nice one.  She had enjoyed sucking it so much
the other day.  Now here it was again hanging out of his pants like a long
sausage.  Her hand went to her mouth at the thoughts that were racing
through her head.  She needed to be fucked, damn it!  And she knew just
where to get some hot ass.  Pulling down on her skirt the teenaged girl set
her mind and her face and walked into the bathroom.  Striking a sexy pose
with her hand on one hip she whispered.  "Joe, don't you think you should
have shut the door before peeing?"

   He jumped and turned around quickly.  His dick bobbed where it hung out
of his pants.  "Sorry sis!  I...  was desperate...!" He blushed.

   She looked down at his meat and grinned.  "Obviously.  Well, next time
think to shut it okay.  What do you think it was like for me coming up here
to find you with your cock hanging out of your pants?"

   He swallowed and moved to stuff it back in.  Ceri laughed deeply and
reached out, catching his wrist.  "Ah ha.  Didn't mean that I wanted you to
put it away.  You have a sexy cock, bro.  You're a sexy man.  I really
enjoyed sucking you other other day."

   He looked into her eyes.  "I enjoyed being sucked." As she watched his
meat twitched and started to form an erection.

   Biting her lip, the teen reached out and wrapped her hand around his
thickening organ.  He gasped and so did she.  It hardened very quickly
then. She loved the way his flesh felt in her palm.  Slowly, instinctively,
she jacked his skin backwards and forwards over his shaft.

   "Oh sis..." "Oh bro..."

   A stair creaked.  Shocked, Ceri let go of her brother's manhood and
snook quickly out of the bathroom.  She heard the door click shut behind
her.  Damn it, she had only wanted to get him down into her room and show
him a good time.  Now she would be frustrated all night again.  Sighing she
entered her room, glancing back over her shoulder to see that it was.  Char
who had come upstairs.  Her future mother looked oddly at her and then
smiled and followed her.

   "Hi Ceri." "Hi Char." "Look, can we talk for a minute?" "Sure, come in."
She pushed open her bedroom door and took a seat on the bed.  Char joined
her, flicking her long hair back over one ear.  She looked very ethereal in
her movements, Ceri thought, like an elf queen from Lord Of The Rings.  "I
just want to talk to you about the other day." Smiled Char.  Ceri blushed
and looked away.  She always found it difficult to look at Char.  It was
like looking at a mirror of herself.  Sure there were differences but the
girl was enough the same to make even Ceri feel odd.  How could her dad
have a relationship with someone who looked so much like his own daughter?
Of course now Ceri knew why - and had enjoyed every minute of that sex. 
"What about it?  Why didn't you just tell my dad?" Char laughed, a deep
throaty, naughty laugh.  "It would have been difficult for me to tell him.
Tell him what?  That I caught his kids having a bit of incestuous fun?  How
would that make me look?" Ceri shrugged.  "Yeah but it was the truth.  You
caught me with my lips around my brother's schlong!" "I don't necessarily
have a problem with it though.  For two reasons.  One, he obviously wasn't
forcing you.  Heck", She touched Ceri's bare knee, "It looked to me like
you seduced HIM!" "I did." Said Ceri shyly.  "Okay, and two...  I've had my
own lips wrapped around your brother's...  what did you call it?"
"Schlong..." Murmured the younger teen.  Her eyes were wide and she was
staring at Char now.  She could not believe what she had just heard.  Her
heart skipped a beat.  Surely not!  Surely Char had not been sucking off
her own future son, the son of the man she loved?  "Yeah, schlong, and boy
is it a nice one to suck!  I must say that he pumps out a good load too! 
Isn't he fantastic?" Ceri could not believe what she was hearing.  She
stood and paced over to the door, shutting it.  "You...  blew my brother?"
"Hell yeah!" Grinned Char.  "You let him cum in your mouth?" "All over my
face actually!  He gave me a big load!  I went back to mine and your dad's
bedroom and licked it all off." "Why..." Ceri stepped towards Char.  "Why
are you telling me this?" Char shrugged.  "I didn't want you to feel bad."
"But...  with you and him it isn't incest.  It's legal.  Joe and I have the
same DNA.  We come from the same sperm." Char laughed.  "Does that mean
that I should do it any more than you?" "No...  I suppose not..." The
thoughts racing through Ceri's head now were a mixture of amazement, shock,
anger and...  relief.  Char was not going to report them.  She did not
appear to mind at all.  It was odd to be discussing having sucked her
brother's lovely juices with another woman.  Char touched Ceri's leg again.
"So that leaves one question...  What do you think of his taste?" Ceri's
face lit up.  "Amazing!" "Exactly!" Cooed Char.  "Problem is, all this talk
of it has made me hungry.  I want some right now.  Do you think you
could... stand watch for me?" "Stand watch?" Coughed Ceri.  She was not
sure she was comfortable with that one.  "Just for ten minutes.  Won't take
longer.  I want you to just keep an eye out for anyone else.  They should
stay down there for ages." "O...  kay..." Spluttered Ceri.  She felt that
she owed Char something for not telling dad about her and Joe.  "But what
should I tell anyone who comes up if they notice you're missing?"
"Hmmmmmmmmm..." Char stood up and paced backwards and forwards.  She put
her fingers to her lips and then laughed.  "How do you feel about being me
for a while?" "You?" Asked Ceri.  "Me."

   The younger teen watched as, quickly and without fuss, Char pulled off
her t-shirt revealing her pert little boobs.  She shook her hair back and
then wiggled down her shorts to reveal a nice red thong that curved up and
over her hips.  Ceri felt a certain admiration for the other teen.  She
guessed it was something to do with their similarities.  Afterall, everyone
has to fancy themselves a little.  That's how people could feel sexy.  So
to see someone who looks almost exactly the same as you standing in front
of you naked should turn you on, right?  Ceri thought back over all the
times she had masturbated in front of the mirror and realised that it was
important to find herself sexy.  She felt herself blush and her pussy grow
wet looking at the other girl.  She was young and sexy and looked great in
lingerie.  Ceri wondered whether she looked just as good in it.  She
ceratinly enjoyed wearing it and being looked at it in.  And the website
she had submitted the photos to sure seemed to like her.  She was running
second now, up for a good prize at the end of the week if it held.

   The spell was broken when her future mother spoke again.  "Nobody can
tell us apart, right?  So if you put on my clothes and kinda hang around
the hallway out there you can pretend to be me.  Then I can sneak into your
brother's bedroom right now and pretend to be you.  He'll be less shocked
if you come in, especially if I heard right coming up the stairs.  You only
have to wait for ten minutes.  If anyone comes up tell them that you're in
bed and you think that Joe is too.  Then go into the bathroom and wait
until they go away."

   Ceri looked dubious, but knew she would go along with the plan anyway.
As a favour returned.  "Okay, since you didn't tell dad." She stripped off
her t-shirt and red skirt.  The teen felt slightly uncomfortable under
Ceri's gaze as she did so.  But then she had checked out the other teen so
it was only fair to be checked out herself.  She wondered if Char found her
at all attractive.  To cover up the awkwardness of the situation she put on
Char's clothes and stood there.  She felt slightly uneasy at the whole
thing.  When Char had put on her clothes though she had a feeling it could
work.  She would not have been able to tell Char from herself, certainly.
So why should anyone else?

   "Perfect!" Giggled Char.
