   "Donald, come here this minute."

   The strident voice of Margaret Mackie hammering up the stairs broke the
tranquillity of Donalds bedroom.  The fifteen year old rolled over and
clambered off his bed, wondering what he'd done wrong this time.  He
quickly ran through his current thoughts and actions and could find nothing
for which he should be worried.

   Still puzzled he made his way downstairs.  Ever since his father had
died three years ago his mother had become more and more waspish and, as
far as he could see, it was all aimed at him.  Therefore when she summoned
him he was always quick to respond.

   The staircase descended into the dining room, completing his descent
Donald found his mother sitting at the dinning table.  She'd only been home
from her job as an accounts clerk for ten minutes so she was still in her
works clothes.  The neat white blouse, buttoned to the neck, and the calf
length straight skirt, that hugged her slender figure, made her look like a
strict school teacher.

   The way she was sat, stiffly upright, with an official looking letter
firmly clutched in her hand made her even more imposing.  She glared at him
as he approached across the neat axminster carpet.

   "What is the meaning of this?" she asked, causing the letter to flutter
in her hand.

   Trying to keep calm Donald asked, "What is the meaning, of what,
mother?"

   "This letter your sister has had to bring home concerning you.  " She
said, her voice becoming shrill, as she waved the letter in front of him.
"You've failed the anatomy module of your biology course.  How could you?"

   Donald stood there a looking confused, his biology course did have an
anatomy module but that was last year and he'd passed it with flying
colours.  He knew his mother had been driving him hard to improve his
grades.  To her, being in the top ten percent wasn't good enough, he had to
be top.  So a letter alleging he'd failed something would be a hammer blow,
but it didn't make sense, he hadn't failed.

   Before he could get his brain into gear and say something his mother
continued.  "Fortunately for you the school have agreed, because your
record so far has been exemplary, to let you re-sit the module and if you
pass then no record of the failure will appear on your transcript.  Do you
understand, you've got another chance?"

   Donald, still confused by the turn of events, could only nod his head in
agreement, 'what on earth was going on here?'

   Margaret turned towards the front room doorway and called out, "Helen,
come in here now."

   Helen, his older sister appeared from the front room, where she'd
obviously been waiting for this summons, a smug grin in her face.

   "Yes Momma."

   "Come here," Margaret said, indicating a spot between her and Donald. 
Helen moved forward and Donald watched on, wondering what this had to do
with him, the rapid turning of events keeping him completely off balance.

   "As you know, after all you did bring the letter home, Donald has a
problem at school.  We," she emphasised, "are going to do everything in our
power to help him through this difficulty, no matter how embarrassing or
demeaning that is.  Don't you agree?"

   Helen still had that smirk on her face as she nodded, "Yes Momma."

   Now Donald knew he was in trouble, Helen only ever called their mother
'Momma' when she was getting her own way, and she'd said it twice already.

   "Your little brother has failed in class, his anatomy class of all
things, so we are going to use your body as a practical teaching aid to
further his education." Donald blushed, he really couldn't fathom out what
was going on and it was getting more embarrassing with each passing
sentence, he glanced at his sister to see how she'd taken the
pronouncement.

   Helen didn't seem in the least bit surprised at that announcement,
Donald on the other hand was sinking further into shock.  If he'd
understood correctly, and he didn't think this was a dream, his mother was
going to expose his sisters body to him, to further his education.  NO WAY!

   Donald looked from one to the other of the women, and lets face it, at
seventeen Helen was a woman for all practical purposes, and they looked
deadly serious, surely this was a joke.  He tried to form the words to
express his opinion but his mother carried on, right over any objection he
was going to make.

   "Now Donald, I want you to go and get your text book on the subject and
bring it back here."

   Donald didn't move, his brain had just quit sending orders to the rest
of his body.  "Donald!  Move your lazy body." His mothers sharp words broke
through his daze and he turned for the stairs.

   As he started to ascend he heard his mothers voice in the background,
"Helen, I think it would be better if you did this in the privacy of your
own room." Donald slowed his pace, listening, trying to get a clue as to
what was happening.

   "Momma, it wouldn't be right, you need to be there, at least to start
with, just to make sure I'm doing it right." His sister moaned.

   Doing what right?  Thought Donald, stationary now on the staircase.

   "Maybe your right Helen." His mother paused in her reply.  "Yes you are.
So what we will do is this.  We will get you undressed here, I will take
Donalds text book and call out the names of various locations.  Donald can
then indicate, on your body, where they are."

   Donald just managed to suppress a gasp, all the earlier comments made
some sort of sense.

   "If Donald does well I will allow the two of you to go up to your room
to continue the studying.  That way you wont be embarrassed if anyone
should come calling."

   She wont be embarrassed, what about me thought Donald as he resumed his
ascent of the stairs.  One thing had changed though, after eavesdropping on
the females of his house he had found that a lot of his anxiety had been
left behind.  He still didn't understand fully what his mother and sister
hoped to achieve, but at least he had an idea of how they intended to
achieve it and that was one thing he was willing to go along with.

   ---oOo--

   Returning to the dining room, the schools anatomy text clutched in his
right hand, Donald pulled up short when he saw his sister stood before his
mother.  That was how he had left them but now his sister was stood in just
her plain white underwear.  A quick glance around the room showed the rest
of her clothes neatly laid over a spare dining chair.

   Resting on the dining table, across the mysterious letter that had
started this strange chain of events was a bamboo cane.  The sort of cane
that his mother used to tie up plants in the garden and the sort of cane
that could be used to inflict punishment.  Was that what this was all about
pondered Donald.

   Before he could take any further action he was spotted by his mother,
who immediately beckoned him forward.  "Donald, find the section in the
book on female anatomy and give it to me." She demanded, "Then take this
stick," she picked it up off the table and waved it in his general
direction, " which you'll be using it as a pointer and get over there next
to your sister."

   Donald flicked through the book finding the illustration that he and his
friends had poured over long before the lesson was due and passed the open
book to his mother.  Carefully he took the cane from his mothers hand and
turned towards his sister.  He couldn't help but look over the body of the
maturing young woman.

   Although he'd had a vague impression that his sister was pretty fit this
was the first time he'd actually looked at her nearly naked form
objectively.  Her mousy blond hair was fairly short, she said it made it
easier to care for it, but it framed a pretty face nicely.  Her body was
well toned from all the swimming she did but she hadn't gone flat-chested
like some of the gymnasts he knew..

   Interrupting his thoughts his mother began, "I'll call out a location
Donald and you will point at it using that cane.  Once we've been through
them once I will let Helen take you upstairs so that you can continue in
private.  Be warned young man, if I am not satisfied with your performance
then that pointer will find another use, a use you man not be very
appreciative of.

   Donald flicked the cane from side to side, listening to the noise it
made as it passed through the air.  It didn't take much in the way of
imagination to feel the shock of impact on his softer regions.  He took a
deep breath to steady his nerves and then noticed the way that the nipples
on his model had surprisingly, sprung upwards.

   "Right, we'll start with the basic skeletal structure.  Donald, all you
have to do is point out where the following bones are in the body."

   Donald moved position slightly so that he could clearly see his mother,
who had the book open on the table and was studying it nearly as hard as he
had.

   "Clavicle."

   Easy thought Donald bringing the pointer up to his sisters collar bone.

   "Sternum."

   The boy allowed the pointer to drift across his sister body until it
rested neatly on the centre of her chest.  He'd been very careful not to
touch either of the breasts encased in the soft sports bra that Helen had
on.

   "Humorous."

   The funny bone, thought Donald and quickly indicated the upper arm. 
What followed was a trip around the body which really caused Donald no
problems, Ribs, Femur or thigh bone, Patella, the knee cap, then the pairs.
The Radius and Ulna in the lower arm followed by the Fibula and Tibia, the
corresponding bones in the lower leg.

   His mother followed up with the two groups of small bones, the
metacarpals, or fingers and the metatarsals or toes.  He had Helen turn
around when his mother asked about the spine.

   Then he slipped, not so much in the answer but with the pointer.  "The
Coccyx?" Asked his mother.  Helen giggled as Donald bought the pointer down
harder than he'd planned on the top of her bum.  The sting shot his sister
upright and silenced her.  Donald, to embarrassed to even apologise,
adjusted his aim until he was pointing at the base of her spine.

   Surprised at the lack of response Donald dragged his eyes off the table
top and noticed that his mother was flushed but silent.  She flipped over
the page in the text book and studied it.

   ---oOo--

   "Soft tissue groups including muscles," intoned Donalds mother.

   Donald swallowed, it had been a long time since he'd gone trough this
and he wasn't sure he could remember everything he'd memorised for the
original test.  Still he'd better do his best as his mother clearly wasn't
going to accept any excuses.  Or, he thought, any explanations how this was
all a big mistake.

   "Biceps, Deltoids..." the list went on containing all the major muscle
groupings.

   "Gluteus Maximus." Once again Helen let out a little chuckle.  Donald,
who had been getting more stressed with each question allowed the cane to
make sharp contact with his sisters, wonderful he admitted to himself,
arse. Another sharp intake of breath all round and a pregnant pause before
his mother continued.

   "Trapezius Muscle."

   Shit, thought Donald, where the hell is that?

   His mother, used to Donalds prompt replies watched, fascinated, as the
cane described smaller and smaller circles and then, like a snake striking,
shot out to the back of Helens neck.  "There."

   "Well done.  Now we'll move on to something you probably know without
the book."

   Donald watched as his mother, then his sister, flushed a delicious shade
of pink.  Surely she's not going to ask me about...

   "Helen."

   "Yes Momma."

   "Remove the rest of your clothes."

   Donald shot his glance from his mother to his sister, who smiled
serenely at him and reached for her bra.  Donald didn't know whether to
look or not but finally hormones won out against modesty.  Helen peeled the
soft sports bra over her head and casually tossed it onto the pile of
clothes.  Her bust was of moderate size decided Donald but more than
adequate.  Helen smiled at her bemused bother then bent forward, straight
legged, to drag her sensible white knickers down her legs.

   Donald swallowed hard and turned to face his mother, half fearing what
he would find.

   His mother seemed to be as fascinated with Helens body as he'd been.

   He caught the flicker of motion in the corner of his eye as Helen threw
her knickers onto the pile of clothes and waited.  His mother looked down
at the text book and called out, softly, "Areola"

   Donald couldn't stop his hand shaking as he raised the cane to his
sisters pert boob.  Her areloa was a deeper brown than the rest of the
boob. Getting the pointer to touch it without touching the nipple was hard,
so hard he felt like grabbing the cane with both hands to steady it.

   He noticed that his breathing was nearly as harsh as his sisters.  He
could actually see her nipples pulsing in time to her heart beat.

   A disembodied voice rang out, "Correct, now the mammary."

   Donald breathed a sigh of relief which caused him to lose control of the
pointer.  Which, in the way of these things, rose slightly then dropped
down, tapping Helens breast.  She moaned in a most peculiar way but before
Donald could apologise his mother called out, "Correct, now the rectum."

   Without even being told Helen turned around and bent over, pushing her
hands back to grip the firm globes of her gluteus maximus.  Donald,
mesmerised by the sight of his sister pert derriere had to be reminded what
he was looking for.

   "Point out her rectum, Donald."

   "Spread or cheeks Helen." Said Donald, softly.

   Helen looked over her shoulder at her brother and gave him a strange,
challenging, look.

   A look that Donald interpreted as 'make me'.

   Without saying another word Donald flicked the cane upwards, striking
the lower part of her cushioned rump.  He'd taken great care to avoid her
fingers and hadn't swung at anything like the force needed to cause any
damage.

   He was surprised then when his sister sobbed before pulling her bum
cheeks apart.  Her rectum was revealed, the pink orifice tinged a light
brown colour.  Donald expected his mother to move on but she didn't, he
glanced over at her and she raised an eyebrow back at him.

   Taking another deep breath Donald touched the little puckered opening
with the very tip of the cane and was rewarded by his mother.  "Correct,
now a nipple."

   Helen released both cheeks, nearly trapping the cane between them and
spun around, rising from the bent over position as she did so.  Donald
could have sworn she was pushing her chest out as far as it would go. 
There was no chance of missing her nipples, they were as hard as any he'd
ever seen.

   As he started to raise the cane to indicate the delicate pink
protrudence Donald had a eureka moment.  Without thinking he followed
through on the thought and swept the cane up, striking the nipple as he
passed, then bought the cane down until it was resting on the throbbing
object.

   He held his breath waiting for some sort of response.  When none was
forthcoming he rolled the cane off the top off the nipple and bought it up
sharply under the other breast, saying as he did so, "This is a nipple,
as," he swept the cane through the second nipple, causing his sister to
hiss, "is this," he concluded.  Resting the cane on top of the second
nipple.

   After a very long pause his mother called out breathlessly, "Correct,
two items to go.  Where is the vagina."

   Donald was lost in the game, a game he didn't even know he was playing.
He drew back the cane then bought it forward until the very tip was
touching his sisters pussy, a pussy that his nose informed him was a little
excited at the current proceedings.

   "Correct, now the labia."

   "Open up Helen."

   His sister refused to look at him and he watched as she pushed her knees
closer together.  He drew the tip of the cane back six inches and flicked
it back against her thigh.

   "Now please," he said, firmly.

   Helen looked at him and Donald couldn't decide whether she was asking
him to stop or to go on.  Running the whole scene through his mind he
guessed that she wanted him to go on, so he drew back the cane again and
bought it down much more firmly across both of her thighs.

   "Squat!  Now!" He barked at her.

   Her knees shot out and her whole body dropped towards the floor,
stopping with her pussy only inches from the carpet.

   Calmly, Donald set out to correct her position.  "Too low Sis, come up
at least six inches."

   Without any hesitation Helen rose up, her pussy lips, glistening,
clearly on display.

   Donald placed the tip of the cane on the moisture and slowly rotated the
cane before looking over at his mother.

   He was staring at her face when she dragged her eyes away from her
daughters exposed body and looked into her sons eyes.  "Correct."

   Margaret gently closed the book she'd been reading from and looked at
her children.  Helen had stood up and was rocking from one foot to the
other, Donald still had the cane firmly clasped in his hand, its tip
glistening with his sister secretions.  Both of them were staring at her,
waiting for their next instructions, unwilling or unable to proceed.

   "Helen, take Donald upstairs and run through the lesson a couple more
times." She turned her eyes to her son, "Make sure you pay attention and
Donald, don't let your sister obstruct your lesson."

   With that she stood and headed for the stairs.

   ---oOo--

   Helen was the first to come out of their collective daze.  She picked up
the text book and without pausing to collect her clothes she headed for the
stairs.  Before she started climbing she looked over her shoulder at her
brother who was still stood there.

   "Come on Don, we've got work to do." Without waiting to see if he would
follow she shot up the stairs.

   Donald watched as his naked sister ran away from him, then, tapping the
cane on each piece of furniture as he passed, he followed.

   In her bedroom Helen placed the book on her music stand and opened it to
the same pages her mother had been using.

   Her brother, hesitantly, followed her into her bedroom.  "Helen?"

   Not giving him a chance to recover Helen started giving out
instructions, instructions that she'd planned out well in advance.

   "Just sit on the bed Donald.  What I'll do is look up a few terms then
I'll tell you one of them and point to a place on my body.  You tell me if
that's right or not.  OK?"

   Donald just stood there.  He couldn't get over the fact that his sister,
his older, much more developed sister, seemed to be happy running around
naked in front of him.  His brain just needed a few moments to catch up and
he was sure that it would all make sense, unfortunately no one was letting
him have the time to get his balance.

   "Donald!  Pay attention." Helen practically shouted at him.  "Sit there
and let's get started."

   He moved to the edge of her bed, taking a casual notice of the stuffed
teddies and pink picture frames scattered around the room.

   "OK, where is my fibula?" Helen asked, then pointed to the side of her
neck.

   Donald sighed, "No, try the bottom part of your leg."

   Helen turned away from her brother and bent from the waist, keeping her
legs perfectly straight with her ankles about twelve inches apart.  She
reached around her calf and tapped her left leg, "Here?" She asked.

   Donald had a bad attack of raging hormones.  His sister was teasing him,
of that he was sure.  Did she expect him to just sit here and take it?  The
cane he found in his hand became a means of making his point.

   He tapped the calf of her right leg, firmly, "The tibia and fibula are
here." He swung the cane to the opposite side of her body and tapped the
left calf as firmly as he had her right one.  "This leg also has a tibia
and fibula."

   He raised the cane a foot and applied it firmly to her thigh, "The femur
is here," a quick crossways swing, "and here."

   Helen started to moan as Donald continued his demonstration.  "These,"
he applied the cane firmly to her bum cheeks, "make up the gluteus
maximus," he paused in his perusal, "and a very nice gluteus maximus it is
too."

   He shook his head, trying to re-establish his equilibrium.  "Do you wish
me to continue, Helen?"

   His sister half rose and turned to face him, "Oh God, Yes!" She
exclaimed.

   Donald stared at his sister in disbelief.  He'd expected to be savaged,
not encouraged.  Still if it was what she wanted he was going to make the
most of it.

   In her slightly stooped position her boobs hung down in a very inviting
position, but he didn't have the conviction to start on them, not right
away.

   He tapped her lower arm, "Radius and ulna," he intoned, before sliding
the cane up her arm.  Even from his position on her bed he could see the
fine hairs rise up.  "This is the humorous," he said before continuing the
canes progress.  "The collar bone, or clavicle."

   Donald swallowed, did he dare?  He'd done it before, hadn't he?

   Hanging there, just beneath the cane where his sisters breasts, bobbing
in time with her breathing.  A nipple firm at the very tip of each breast,
just waiting for his attention.

   He lowered the cane slowly, then accelerated it sideways, bringing it
smartly into contact with the dangling mass of succulent flesh.  "A mammary
gland," said Donald, "otherwise known as a breast, or a boob, maybe even a
tit."

   Donald waited until Helen made eye contact again, "Don't you agree?"

   Helen was panting and had to struggle to answer her brother.  "Yes sir,
tits is what they are." She paused, then added, "they've also been called
fun lumps as well.  Are you having fun with them?"

   Am I?  Pondered the younger sibling.  It felt like it.

   So why is this happening?

   Taking his time, and tapping the cane against the hanging fun lump,
Donald decided to find out what was happening.  Pausing the cane he asked,
"So Helen, where did that letter come from?"

   "School."

   Donald shot the cane into the delicate flesh of Helens breast causing
her to flinch.  Only clenched teeth stopped her calling out.

   "Sorry Helen but I don't believe you.  Anatomy was last semester and I
got the A you'd expect me to get.  So, once again, where did the letter
come from?"

   Helen, her eyes glistening with unshed tears looked at her brother, "I
made it up."

   "Why?" He asked, totally confused.

   Donald watched as his sisters throat contracted in a swallow.  The tears
started to flow down her cheeks.  "This," she said, her hands indicating
her naked body, "I wanted this."

   Donald still looked puzzled, so Helen continued.  "I knew mom would be
upset when she got that letter and, if I was careful, I could get her to
strip me in front of you." She paused for a moment, waiting for Donald to
say something, when he remained silent she continued, "I like being
humiliated, Don.  I know it's perverted but it does things to me that I
can't get any other way."

   "So this was all about you, not me.  I was just a means to an end?"

   Helen hung her head, "I guess you're right.  I didn't really think how
this would affect you.  I'm sorry Donald.  I'll go tell mom now."

   "Stand still!"

   Helen froze in place.  Donald, after a moments thought, spoke up. 
"There's no need to see mom.  I'm sure I can take care of this myself." He
tapped Helen on both of her breasts with the cane, "If you want me too."

   ""What do you have in mind?" Helen asked, cautiously.

   "Well, you have been a naughty girl," said Donald, "and when you're
naughty you have to be punished, don't you?"

   Donald found himself holding his breath, waiting for his sister to
answer.  He found that he really wanted her to accept his right to punish
her.  He watched as the conflicting emotions shot across his sisters face
until, after what seemed like an eternity, she raised a watery smile and
nodded at him.

   "Then I think a simple spanking should be sufficient.  Don't you?"

   "How many?" She asked.

   Donald just said the first number that came into his head, "Six." Why
six, he questioned himself, well, it was always six of the best, wasn't it.

   Donald jumped to his feet and crossed to the dressing table, with a
flamboyant sweep of his arm, he cleared the top of the cuddly toys.

   "Helen, come here and bend over." The chest was waist height on his
sister.  She'd be able to rest on its top whilst keeping her legs straight.
It would also give him plenty of room to swing the cane.

   Ever so slowly Helen shuffled over to the chest of draws.  Donald could
tell that she was having second thoughts and sought to encourage her. 
"Come on Sis, the sooner we get started the sooner it'll be over." Then in
a quieter voice he added, "I won't go over the top, honest."

   Donald was surprised at how trusting the look his sister gave him was.
Although they'd not been enemies they hadn't been particularly friendly as
they'd grown up.

   Donald watched as Helen lowered herself down.  She lay one arm down the
length of her body and the other was across her boobs.  In position, Donald
moved so he had a clear swing at her glorious ass, he drew the cane back
and, just before he started to swing said, "Keep count Helen, keep count,"
then his arm swung firmly through an arc.

   ---oOo--

   Donald was shocked at the noise the cane made as it impacted on his
sisters taught behind.  It was followed moments later by his sisters
explosive release as she gasped, he assumed in pain.

   "One."

   Donald pulled the cane back to its starting position and hesitated as a
bright red mark was revealed across the fleshiest part of Helens bum. 
Taking a steadying breath Donald swung again, just as firmly.

   He was fascinated as the impact rippled across the soft flesh of his
victims body.  How much of that was due to Helen flinching he couldn't say.

   "Two," counted Helen.

   Donald drew back the cane and paused, he had to be sure.  "Are you OK
Sis?" He asked.

   Helen rolled her head to the side and looked at her brother.  A look
that seemed to convey love, lust and a desire to continue.

   Donald just nodded, Helen was OK.

   He whipped the cane forward, aiming a little higher, maybe travelling a
touch faster.

   The crack it caused seemed to echo around the small bedroom.

   Helen gasped, then moaned.  Drew in a breath and sighed, "Three."

   As Donald pondered his next shot he watched the fingers Helen had, on
her tit, toy with the nipple, flicking and stroking it.  Then, grasping it
between finger and thumb she squeezed, hard.  God, he thought, that has got
to hurt.

   He swept the cane in low, guiding it upwards, under the overhang of her
cheeks.  It wasn't as hard or as fast as the earlier shots but its
direction seemed to catch Helen by surprise.  She went up, high, on her
toes before squeaking out "Four."

   She shuffled as she lowered herself back down onto the chest, her legs
opening a little more as she did so.  Donald, wanting to get a look at his
sisters pussy, took a half pace to his right and looked.  The first, and
most surprising thing, he saw was his sisters fingers, wiggling in what was
obviously a swamp.

   Donald just couldn't understand how someone could be so turned on by
pain.  Then again, he thought, acknowledging the hard on he'd had ever
since he entered his sisters bedroom, some of us seem to be turned on by
inflicting pain.

   He paused, watching the fingers.  Waiting for them to slow down.  As
soon as they did he struck, firmly.  The red line of his shot half way
between the pulse orifice that was her rectum and the glistening fingers
stroking her pussy.

   "Five!" Exclaimed his excited sister.

   Donald watched as she bounced her pussy up and down on her wiggling
fingers.  He lost track of time as he became engrossed in her masturbation.

   "Please." He heard.

   He shook his head slightly, "Please Donald, hit me." He drew back the
cane, waiting.

   "Hard!" She begged.

   It was too much.  He swung as hard as he could, part of his mind glad
that the cane was so short.  The impact vibrated through his hand.  His
ears shook as Helen screamed, a scream of pain and release.

   "Sihhhhixx"

   Helen slumped, her whole body limp.  Donald stood, rooted to the spot.
Unable to move, either to assist or run.  He just waited, flushed with
success and remorse, a very heady mixture.  One thing was sure, his rock
hard cock just wanted release, any way it could get it.

   Oh so slowly Helen started to regain an awareness of what was around
her. The throbbing from her ass was exquisite, all she'd ever hoped it
would be.  As her eyes opened, she saw her brother, stood there staring at
her, a looked of bemused interest on his face.  She smiled.

   "You OK?" He asked.

   "Uhhmmm," she nodded.

   "Good," came the reply.  "Then I think we should continue with our
anatomy lesson, don't you?"

   What could he possibly mean, carry on the lesson.  She raised her head,
then flinched, as Donald bought the cane down on the chest of draws, inches
from her nose.

   "Come here Helen."

   She shook herself then struggled to stand, her legs, like the rest of
her, was completely drained of energy.

   Donald backed up until he was next to her bed, "That's right, Sis.  Take
your time." He paused, waiting for Helen to move towards him.  When she was
an arms length away he spoke again.  "So far we've covered female anatomy,
now it's time to look at things from the male perspective." Donald smiled
inwardly, pleased at how he'd phrased that.

   "Drop down to your knees, so you have a clear view.  Be careful, don't
hurt your bum any more."

   As Helen lowered herself she began to realise what Donald was on about,
especially when he lowered his trousers and underpants.

   "I think the cane is a little too large for the necessary pointing Sis,
so I'm going to leave it up to you what you use instead."

   Donald opened his legs slightly and Helen watched as his balls settled
and his hard cock throbbed, it's purple head already leaking fluid.

   "Right Sis, where is the scrotum?"

   Donald, and Helen, watched as her hand came forward and her fingers
gently lifted the young mans ball bag.  "Here." she intoned.

   "What are those things inside the sac, Sis?"

   She looked up, "Balls."

   "That's right, balls.  Otherwise known as testicles.  They produce
sperm, and at the moment they are very, very full."

   Helen nodded.

   "Now, what is that sticking out above them?"

   "A dick," she said, giggling.

   "Perfect, a dick, cock or prick, though technically it's a penis."
Murmured Donald.

   Helen, her hand still fondling a pair of full balls, looked at her
brother.  Waiting for him.

   "Helen, touch my penis, please." Donald was almost frantic, his voice
rose in pitch as he almost begged his sister to give him some sort of
relief.

   Helen raised her second hand, leant forward and lightly gripped the hot,
throbbing shaft.  Above her Donald groaned.

   "Stroke it Sis, stroke it." He begged.

   Her hand started to slide up and down the velvety shaft, her own
enjoyment fuelled by the excited noises her brother was making.

   "Yes, yes, that's it.  Oh God, yes." He rambled on, getting closer and
closer.

   "Kiss it Sis, go on, quick." He demanded.

   Helen rocked forward and placed her lips against the very tip of Donalds
cock.  She felt it burning its way into her mouth.

   "Yes, that's it, suck it, suck it." Donald flexed his hips, forcing the
tip of his dick further into his willing sisters mouth.  He rocked back and
pushed forward once more.  He dropped his hand to the back of his sisters
head and grunted as his whole body spasmed.  Spunk flew from the tip of his
dick and coated the inside of his sisters mouth.

   Helen, her eyes wide, felt a mans sperm in her mouth for the first time.
She wasn't a virgin but somehow she'd not been called upon to perform oral
sex before.  Now she had a mouthful of stuff and didn't know what to do
with it.

   Donald looked down, his hand sliding from behind his sisters head to her
cheek.  He stroked it gently before telling her, "Swallow Sis."

   Helen, totally lost in the feelings the last half hour had generated
just did as she was told.

   Donald lifted his sister from her knees and then pulled her against him
before slipping backwards onto her bed.

   "Lets just relax here shall we?" He asked.

   Helen just cuddled up against him.

   ---oOo--

   "Donald," Helen said quietly, "if you promise to keep using me for your
anatomy lessons?" She paused, ensuring she had his undivided attention,
"I'll let you into a little secret, a secret that you would love to know."

   Donald raised his head from the mattress, "You mean you want me to carry
on, like we just did, with the cane and everything, Sis?"

   "Oh, much more than that, Donald.  I want you to see how much I like
being told what to do and," she paused allowing her eyes to drop to the
cane that Donald had dropped on the bed, "just how excited I get when I've
been punished for being a naughty girl."

   Donald looked at the glowing pink cheeks of his sisters backside and
felt a corresponding glow within.  He'd enjoyed touching and then applying
the cane to his sister and wanted it to continue, especially if she would
keep sucking his cock.  "OK Helen, you're my anatomy model from now on, I
promise."

   A shudder ran through the soft female body before him, almost like it
had just reached another climax.  "Thank you Sir, for doing that for me."
Again she looked him in the eyes, then taking a deep breath she continued,
revealing the secret she'd promised.

   "Momma has the same dreams, and feelings about this," she waved her arm
at the cane and the bed, "that I do!"

   The curious look on Donalds face slowly turned into a delighted smile,
"And you think..." He left the question hanging between them.

   Helen nodded.

   "Yes," hissed Donald.  Momma too...
