INTRODUCTION

Justin Rogers was born with something special - a 
complete functional set of female sex organs.  Eventually 
he found they didn't really belong to him but to his twin 
sister Tina who spent much of her early life sharing his 
body.

Since she is able to emerge from and rejoin him, they 
share their memories, their experiences, and their sexual 
desires.  They shared each other and later the delectable 
Kaitlyn, or Katie, Norton.

*********************************************************

PREVIOUSLY

Katie's brother David had unexpectedly "satisfied" two 
sisters and as a result had appealed to Justin and Tina 
for assistance learning more about the ways of pleasuring 
women.  Tina had agreed to teach him, and his friend 
Douglas.

*********************************************************
    Continuation from Chapter 22 while the
    events of Chapter 23 have taken place.
*********************************************************

Doug had tasted pussy!  And like it.  Given every 
suggestion that muff-diving was being considered for an 
Olympic event - at least in this house - Doug had no 
reason to think he wouldn't.

Still, as the saying goes, "the proof... is in the 
eating"!

In this case the eating showed how delicious Tina was, 
and that Doug was more than just a fast learner.  Tina 
had complimented him on his technique - and none of the 
comments had been in English with the exception of a very 
clearly enunciated "YES!".

Of course David wanted to claim credit for laying the 
groundwork and Tina couldn't entirely discount his 
efforts.  Though she had stopped David before reaching 
orgasm and had rested between contestants, Tina lost only 
a little of the edge David had created.

They had both been given high passes and both felt Tina's 
guidance had been invaluable in understanding where, when 
and a number of hows - how long, how hard and 
(conversely) how soft.

Tina let her body relax, recovering before her next 
challenge for them, something neither youth had expected 
and which Tina herself had only decided upon after 
viewing the material at hand.

And not it was, if not at hand, at least in hand.

Tina carefully held a penis in each hand; she was careful 
in the same way in which she would delicately handle a 
loaded pistol with no trigger guard or safety - the 
simplest jarring might set it off.

Tina wasn't quite sure what to do with the two boys.  She 
WANTED to feel Doug's prick inside her, to be able to 
compare it to her own - well to her brother's.

It was strange for Tina.  Sometimes she would reach down 
to shift her balls or her prick, some sensation 
triggering Justin's response.  She knew he similarly 
reached up at times to adjust his non-existent bra under 
his equally missing breasts.

She wondered how these two young men would react if they 
found her with a penis.  Probably with some dismay!  
Katie had certainly learned to live with and make love to 
the odd juxtaposition of organs when Tina was "hiding".

Still it wasn't as if she suddenly had a penis, it was 
rather that Justin "grew" a vagina when they merged.  He 
was fortunate that her breasts only made his pecs a 
little better developed when they were together - instant 
workout!

Justin had been subjected to stories of how size mattered 
even though simultaneously it didn't matter and didn't 
know what to believe.  This of course meant Tina had 
similar opinions or rather doubts.  Doug's "endowment" 
gave her an opportunity to finally make up her mind.

Tina WANTED Doug inside her but she would then have to 
extend the same courtesy to David if she wasn't going to 
be a thorough bitch.  It wasn't that she wouldn't screw 
him as well but if Doug went first would David rattle 
around inside?  If she blew Doug while David fucked her 
(or even if Doug just watched them while he waited for 
his turn) Tina felt sure he would come - and was quite 
unsure if he was up to a third attempt, the first being 
the "friendly" hand job he and David had shared in the 
shower at her instigation.

She wasn't doubting Doug's stamina, merely her luck.

No, David would have to wait this time.  It was only fair 
(at least for her) that Doug have some opportunities to 
go first as well as David.

For Tina it was a time of firsts as well.  It was not 
only her first time with TWO males, it was also the first 
time she had fucked a male other than Justin.

Tina started explaining about condoms.  Though she had 
made sure her diaphragm was securely fitted and she was 
not in the more fertile part of her cycle, she had 
forgone the use of spermicide since the boys would be 
licking her out.

She wanted a little extra precaution in case her 
diaphragm moved around but also because she only had 
Doug's word that his prick hadn't been anywhere nasty.

The gang could only relax together knowing the five of 
them remained "faithful".  Tina effectively had a 
dispensation to fool around that night but that didn't 
mean she could carelessly bring back an infection.

Finally, though the other issues meant it was never to be 
a consideration, Tina doubted either boy would be as 
comfortable fucking her if she was filled with the 
other's semen.

David watched Tina unfurl the rubber over Doug.  It might 
have been a case of one size fits all but there was a lot 
of difference between a tight t-shirt and a loose blouse.  
Tina had to ROLL it down the full length of Doug's shaft.

Doug wasn't sure which was worst - the feel of Tina's 
hand, the anticipation of losing his virginity or the 
fantasies of fucking that his curious mind kept bringing 
up.  None made it any easier to hold back his own 
release.

In recognition of his size and inexperience, Tina opted 
for a position where she had more control and traded 
places with him.  She then straddled his hips with the 
organ she craved poking up in front as though it was HER 
erection.

"Don't worry if you come - you'll stay hard for a while; 
long enough I hope."  Tina smiled at Doug.

She lifted herself and positioned his prick beneath her 
body then let her weight slowly impale her on the rigid 
stake.

Tina was right on two counts.  Doug DID come, and very 
quickly, and he DID remain firm enough for both of them,

As her opening stretched over his prick Tina could feel 
the sudden relaxation as the head passed through, though 
the shaft was only a little narrower.  It was a 
duplication of what Tyler had experienced but far less 
extreme and Tina felt nothing but pleasure as the veined 
surface rippled by.  Doug's prick reached the end of her 
vagina before Tina came to rest against his legs and she 
was forced to reverse her movement, once again slowly 
sliding over the surface.

It was too much for Doug and Tina had no way of avoiding 
the movement of his hips that lifted her above the bed.  
Doug HAD to get back inside her, had to feel the friction 
of her body over his, had to fulfil his own body's urges 
to impregnate her.  It was pure instinct and Tina, 
impelled by similar feelings, was loving every minute of 
it.

Had Doug been on top she may have found the piston-like 
movements overwhelming but his ardour was tempered by an 
inability to overcome the constraints of his supine 
position.

The "worst" of his release passed and he lay quieter 
while Tina resumed her previous slower fucking.

For Doug, each moment had been exquisite torture.  He 
WANTED to hold back, to show the obviously experienced 
girl that he could be a competent - hopefully excellent - 
lover but his body had betrayed him.  To one who, before 
that evening, had only known the embarrassment of waking 
soiled from a delicious dream or the caress of his own 
hand it was the best and worst of times.

He had fucked (F-U-C-K-E-D!) a girl (AND it was still 
happening!).  He had watched her naked body - was there 
anything better? - watched it engulf his turgid organ; 
had felt her wetness sliding over the most sensitive part 
of his body; had touched her very depths.

And then had spoiled it all, (despite what Tina had said 
he just KNEW she would be disappointed), spoiled it by 
exploding as she had lifted herself up again; far too 
quickly.  Would he ever have a chance to show her he 
could be more?  Or was he cursed with as short a fuse as 
he was supposedly blessed with a large organ?

Tina suspected he might feel that way.  After all, she 
had experienced every doubt Justin had had when they were 
first learning about love and lust.

"Just work with me.  It feels lovely and if you just wait 
you'll find yourself getting ready again."

Justin had no trouble coming three times, could manage 
four when the need arose, and had even performed very 
weary five times on one extended night - Doug should be 
good for a third.

Doug had not increased in size much when he had gotten 
hard which was probably good for his sexual future as 
well as for Tina.  It meant that when he softened there 
was little difference and, since there was not enough 
room under Tina for it to curl around snakelike, his 
penis was nearly as satisfying in its weakened state.

Tina decided, since she was no longer being madly bounced 
around, that she could employ other means to bring Doug 
back from the not quite dead.

"Put the other condom on David."

The other boy had been intently watching, a much better 
spectacle than he had ever seen before.  His prick had 
only had a the briefest chance to droop when the 
expectation of getting his own chance to fuck the 
delectable Tina had reversed THAT trend.

Of course, Doug's first thought when he heard Tina's 
instruction was that he had blown his chances as well as 
his load.  That changed when Tina kept up her slippy-
sliding motion and pulled David closer by a hand on his 
butt.

If someone had bet Doug at lunchtime that by 9 pm that 
night he would have jerked off his best mate, been jerked 
off by him in turn, showered with a lovely young lady, 
eaten her pussy, fucked her *OR* watched her give said 
best mate a blowjob, Doug would have lost an awful lot of 
money on each and every item.

And it would have been worth every cent!

How could he NOT stiffen again at the sight of David's 
prick disappearing between her lovely lips.  It was 
something he figured might never happen to him 
considering the monster that hung between his legs.

In this he had the poor view that teenagers quite 
commonly had of their own bodies.  That was one reason 
why he was interested in learning alternative means of 
providing them pleasure.

That Tina had fitted snugly around him did little to ease 
his self-doubts.

But David's prick; well, that obviously fitted nicely 
into Tina's mouth in its orange jacket.  Doug's own prick 
was sheathed in green.

As he watched Tina bobbing her head along the horizontal 
pole Doug could feel her moving up and down his pole as 
well.  He tensed his muscles, moving his body slightly in 
opposition to her oscillations.

"Mmm."

Was that Tina or himself?  He had gotten harder but Tina 
was still rubbing her body against his.  She hadn't been 
able to fit him in before - had she shrunk?

Tina had relaxed enough to accommodate the extra length 
with little discomfort.  Now she felt full while her clit 
could still bump along Doug's pubes.  She was getting all 
the right touches she normally got when fucking her 
brother but now she had a balloon swollen inside her, 
rubbing ALL the places at once.  She was glad she hadn't 
missed this opportunity - maybe the others would like to 
try him too.

They didn't come together though one event triggered off 
the next.

David came first.  He had enjoyed feeling other mouths on 
his prick when he had been blindfolded; he had come in 
Ainslie's mouth while busy eating her younger sister's 
pussy; and now Tina felt the pulsations as he filled, not 
HER mouth but the thin rubber sheath.

David decided that the condom had its pluses and minuses.  
He had certainly felt more when Ainslie had blown him but 
she had stopped as soon as he come - Tina worked every 
last drop from his prick until he was nearly ready to 
scream for her to stop.

Tina released him and looked at the bulb on the end.  
Apart from a bubble it was full and the excess, a 
transparent liquid that coated his knob, showed David had 
ejected a generous quantity of semen.

Doug could see it too and the evidence that his friend 
had come in Tina's mouth inflamed his own desire; he 
began to push up harder into Tina's body.

"Roll with me", Tina instructed and she gripped Doug's 
shoulder.  Doug's prick slid out as they swapped places 
but it had a long way to go and he remained inside her.

The loss of a few centimetres only meant he had a run up 
when it was time to bury it once again.  Despite the 
urging of his body he was careful on his first stroke, 
more enthusiastic on his second and up to full steam on 
the third.

Tina had heard of "nailing her ass to the wall" - she 
felt she was being jack-hammered to the bed.  The 
mattress was certainly flexing and the springs were 
singing.

After all her efforts to keep things slow it was a 
welcome change and she let Doug know she was about to 
come.  It was obvious to him when she did - her reaction 
was to colour his outlook and it was quite a while before 
he was convinced a girl had come as a result of his 
efforts; he thought, no matter how much they expressed 
their satisfaction, that he was just missing the mark 
somehow though he couldn't work out how.

With Tina writhing underneath him, clawing his back and 
making enough noise to disturb HIS parents blocks away, 
Doug had no chance of avoiding his third release for the 
night.  At least he felt this one should win him some 
accolades!  It did.

---

Tina needed a rest; the boys needed a clean up.  She sent 
them on their way with one parting instruction.

"David, can you please have a word to Katie?  Just say 
'Two more please if you can spare them'."

David, not believing his luck, nodded, turned and 
grinned.

...

When David got back with the condoms he found the others 
hadn't waited for him.  Doug was on his back with his 
legs over the side of David's bed and David could see the 
crown of Tina's head as she sucked on Doug's prick while 
he ate her.

That took a little getting used to.  Not the act of 
watching his best mate being blown or any of the rest of 
the evening's pleasant activities but rather the contrast 
in size.

At least Tina had given no indication that she found him 
in any way inadequate though she *HAD* seemed extra 
pleased when Doug had built up some speed.

David didn't think to wonder how much of that had been 
real, how much his subjective outlook, and how much was 
simply his freedom - as an observer rather than as a 
participant - to pay more attention to what was going on 
rather than having the distraction of his own orgasm.

Tina looked up.  "Have you washed?"

David had freshened up on the way to his sister's room, 
not minding that he appeared naked but preferring not to 
be dripping cum onto her carpet.  "Yes."

"Well stand over here where I can suck on you too."

David moved closer and Tina guided him into place between 
Doug's knees.

Tina put one hand on Doug's prick and took David's in the 
other, pulling the foreskin back so the bare heads 
touched.  It was weird to have his prick held against his 
friend's, their balls dangling together with a tickling 
touch - Did Doug feel the same way?

Tina ran her tongue sideways back and forth across the 
border between the aligned dick heads then circled them 
as she linked her fingers to clamp both organs together.  
Fortunately Doug's extra length allowed her to align them 
part way down the length rather than being limited to 
just holding colliding knobs.

She opened her lips and ran her tongue around them so the 
soft red surfaces glistened wetly.  Tina moved her head 
sideways so that she approached from the side with her 
mouth stretched wide.  Doug felt a lick before Tina's 
lips made a firm contact; then they slid along as she 
tried to ease David's prick in as well.

Tina worked her way over the smooth surfaces, gradually 
making a little headway each time she moved from one side 
to the other; it wasn't long before she decided she 
*COULD* do it.

It wasn't comfortable; in fact it was downright painful 
for both her jaw and the sides of her mouth.  Tina felt 
as though they were splitting at first but the pain eased 
as she worked things around until they fitted more 
comfortably.  Then she started sucking and licking the 
"things" in earnest.

There was no head bobbing - her mouth was too full for 
that!

Doug and David were appreciatively silent; but they 
relived every second afterwards as they discussed it in 
great detail.  It was almost as if they needed to 
reassure each other that such an incredible event had 
actually occurred.

Doug missed the sight that David was getting though both 
could feel the other's prick rubbing against his own and 
the difference inside Tina's mouth.  It was only his 
ongoing state of recovery that stopped him (either of 
them) from flooding Tina's throat as she continued to do 
wonderful things to him.  He did what he could to return 
the pleasure she was giving him, reinforcing the lessons 
she had so recently been teaching him.

Reluctantly calling a halt to a novel experience - she 
couldn't wait to share the story with the others - Tina 
wanted to give the boys yet something else to consider.

She had been the bottom slice in a Katie sandwich while 
Justin pounded her pussy over Tina's face; she wondered 
how Doug would cope - his tongue had been doing wonders 
so far.

"Suit up", she told David and, when he had slipped a 
condom on, put her hand out for another.  "I think I'd 
like to see how good a fuck you can give me now you're 
calmer."

Tina then ignored David as he walked around the bed, 
wrapping Doug's prick before she started blowing him 
again.

Doug's head was just over the side of the bed so he could 
see his classmate approaching.  He relaxed so his head 
dropped and, with an "Excuse me" from David, he watched 
his friend's colourful entry above his face.

The whole evening had been a lust filled fuck fest that 
Doug would never have imagined in even his wildest 
fantasies.

It wasn't a case that he *COULDN'T* have imagined it - he 
did have a pretty active imagination when it came to 
matters sexual since he had little opportunity to do 
other than think about it.  No, he *COULD* imagine such 
fun; he just wouldn't have combined the events in one 
session and he had never imagined sharing them with 
another male.

Still, given a choice of sharing the adventure or missing 
out, Doug accepted the proximity of his friend's prick 
while enjoying the feel of Tina's mouth once more 
engaging his.

As David eased himself inside the young woman, 
unnecessarily careful since she was both wet and willing, 
the lubricating juices were expelled to run over Tina's 
pussy and to fall, a sweet and scented rain, onto Doug's 
face.  He licked his lips and chin and then raised his 
tongue past David's swinging balls to once again rub the 
tip over Tina's moist furrow.

Doug hoped he didn't offend David's sensibilities bit, 
sensing no hesitation in his rhythmic thrusts, figured 
any apologies could well wait until later.

Having someone else's scrotum and its pendulum-like 
contents striking the bridge of his nose was an unusual - 
he wouldn't *REALLY* call it interesting - experience.  
Though Doug later likened it to a wrecking ball knocking 
down the side of a building, it didn't cause him any 
discomfit, even when David began to really bury himself  
as a prelude for coming for the third and final time that 
night.

In fact, David's thumping against Tina's body caused more 
effect at Doug's other end.

Trying to keep the larger than accustomed organ in place 
as her body was rocked back and forth, it was inevitable 
that Tina caught her teeth on the collar of Doug's knob.  
Sometimes it was a pleasant difference, sometimes an 
exciting annoyance and sometimes a painful attack.  Doug 
could never be sure just when the soothing (No, 
definitely *ANYTHING* but soothing as his pulse rate 
rose), ...the soothing touch of her lips would be 
replaced by the grazing or jarring impact of her 
incisors.

After one particularly unpleasant incident, Doug leaned 
his head back so David's balls, instead of surrounding 
Doug's nose, slapped against his mouth.  Doug waited, 
judging their motion, and seized just the hairy skin as 
David receded.  Unable to stop just because he had 
registered a most unexpected attack on his person, David 
felt his flesh catch and then pull through his friend's 
gently clenching teeth.

There was no damage done, that was never Doug's 
intention, and David found the unexpected short burst of 
pain actually brought a rush of adrenaline that meant he 
needed to bury himself as deeply as possible.  He thrust 
once, twice, a more violent third time and then paused at 
maximum depth on the fourth as his seed was released from 
his body.

Doug's face was once again flooded and he too came from 
the pressure of Tina's mouth just as violently fucking 
him.  Tina let his organ escape from her lips, the rubber 
bulb barely filled with the lesser quantity of semen - 
all that his depleted balls had been able to provide.

Above his face, David carefully held the rubber around 
his collapsing prick before he collapsed over Tina's 
back.

Though his legs remained straight enough to support him, 
his penis had no chance of maintaining a similar 
rigidity.  It drooped down, right into Doug's face.

Doug, who had been trying to cope with the exudations 
from Tina's cunt without disturbing her now sensitised 
clit, now had to cope with a condom-coated prick resting 
against his lips.  He had bitten David's ball sack in an 
effort to get him to change his actions, maybe something 
similar would get him to move.  Certainly opening his 
mouth to complain would only result in David's prick 
dropping into the opening so Doug figured he might as 
well do something himself as just lie there.

David felt the movement of lips brushing over his prick; 
he felt the sensations of a mouth surrounding it and even 
a tongue brushing across the surface as Doug moved it out 
of danger.

Then he felt the insistent and increasing pressure.  
*NOT* a nice way to be asked to move.

Doug, sensitive to his own organ being potentially 
vulnerable if not currently in danger, only bit down 
gently and then paid careful attention to David's 
reactions as he increased the force applied by his jaw.  
When the noise changed from shock to complaint he stopped  
and relaxed.  David's prick slid past his lips and Doug's 
tongue made another brief contact as the prick 
disappeared.  It certainly wasn't an activity he had made 
any conscious decision about - it had merely been in 
response to the circumstances he found himself in.

As David moved out the way and Tina rolled off of Doug, 
Doug could taste the rubbery flavour overlayed with a 
slight hint of fruit.  Tina's own delightful musk was no 
longer registering with his taste buds - they needed time 
to recover as well before he would again appreciate her 
flow. 

It was an opportunity that he was not to have that night; 
indeed he did not know if he would ever get another 
opportunity to sup from her most attractive bowl.

He was in love - she *WAS* his first - and could only 
dream that she might be moved to seek him out again.

Fortunately, if there is one attribute that teenagers can 
have is almost as great a degree as their sex drive it 
can be optimism, however unfounded.
