 MPAs in public life - vignettes

   Mum, widow 36 Alice Husband: Thomas.  Died 2 years ago Daughter 17
Fran(cine) Son 15 Mark

   Widow, 36, has teenage son 15, and daughter 17.  Mum has been without
sex for 2 years.  She signs herself and kids up for the MPA program.  By a
paperwork error, she's given her own remote, as opposed to them being
enroled in a community program due to being a household without husband. 
She's an unadmitted submissive, never having met a dominant man.  Was
always very prone to masturbation, and secretly longed for a man to 'take
charge' of her.  She also finds herself having fantasies of her daughter
being subjected to sexual domination by the same dream man, and him making
the two of them 'do things' to each other.  Several times in the last year
she has spied on her daughter masturbating, then deliberately waited till
just before the girl was about to orgasm before bursting in and lecturing
her.  Somehow it gives her a sinful thrill to rouse at the girl, all the
while knowing she is achingly frustrated.  She forbids daughter to lock her
door, takes bedroom key away.  She's also often seen her son with an
erection in the morning, and at other times.  Somehow she never felt
confident to burst in on him when she knew he was masturbating.  Instead
she goes to her own room and fantasises naughtily about forceful men and
what they do to helpless women.

   When she finds herself with the family MPA remote, she tries to do the
right thing.  She isn't very technically minded, and finds the remote's
operation confusing.  So she just sets it to do the one thing the publicity
materials strongly recommend - prevent female orgasm, since both she and
her daughter are single.  It doesn't occur to her to disallow masturbation,
and it's some weeks before she's even aware it's possible.

   Of course she (and her daughter) start to become really frustrated. 
After about three months she can barely think straight, and her daughter is
showing signs of strain though she won't say why.  Mum finds it's becoming
dismayingly common to catch her daughter playing with herself.  Her own
fantasies become more intense.  She reads the reports that it's best for
male teen genital development to have frequent erections but only
infrequent ejaculations.  She becomes very centered in her fantasies on the
frequency of her son's erections, and ways of increasing them but
preventing him from orgasming 'too often'.  But she's too timid to actually
do anything about this.  She takes to sending son off to ask daughter
something, or fetch something from her, when she knows daughter is
masturbating.  Mum tells him there's no need to knock since it's a good
thing if he catches his sister being naughty.  Naturally he's happy to
follow her advice.  He often catches the girl, and becomes quite good at
sneaking up on her, and watching quietly.  Of course this gives him a
rock-hard erection every time, and for a while mum does nothing about him
going back to his room to beat off.  She waits till he's left, before
walking in on daughter herself, and berating the girl.

   Then mum finds a way to spy on her son masturbating, and her fantasies
take on a new dimension.  She decides she _has_ to reduce the number of
times he ejaculates, any way she can.  So now she sets up scenes where son
'catches' daughter maturbating, and leaves him to watch a while, then just
before she thinks he'd go to jack off she bursts in on daughter.  Then she
calls son in, and tells him to stay and watch as she punishes daughter. 
Subjects naked daughter to humiliating lectures, examination of daughter's
'naughty pussy', lengthy spankings, and other punishments such as ordering
the girl to remain naked when inside the house.  All the while requiring
son to stand and watch, fully clothed and unable to relieve his aching
hardon.  Which she openly acknowledges but does nothing about.  She
comments that she's read it's best for young men to have erections often,
but to mostly avoid ejaculation.  Then she makes son stay in her sight for
rest of the day whenever possible.  While making a very poor secret of her
own arousal, thus prolonging his erection.

   She knows she could use the MPA remote to regulate her son's
ejaculations, but somehow feels reluctuant to do so.  It feels deeply wrong
to her to prevent her son's sexual spurtings, and she also strongly
suspects that if she was confronted by her son, erect and demanding she
stop controlling his orgasms, she wouldn't have the strength of will to
resist.  Not to mention that she very much enjoys spying on him jerking off
and jetting his seed.  This goes on for weeks, with her torn between her
own ever-building desires and her motherly wish to do what the documents
say is best for him.

   Finally things come to a head when Fran finds Mark masturbating in his
bedroom, and runs to tell mum.  It ends up with her and her daughter
bursting in on him just as he's spraying up into the air.  He'd been
reaching for a tissue but they interrupted before he could get it.  So they
are standing by his bed, with him lying there naked on his back, stomach
covered with sticky streaks of semen, and reddened erect cock in his hand.

   Daughter seems to expect some kind of equivalent to the punishment she
gets for masturbation, but mum reads out the sections of the MPA user guide
which explain that female and male sexuality are acknowledged by the State
and law to be different, and males do have an overriding phsyological
requirement for periodic relief.  Without which various medical and
psychological harmful effects are strong risk factors.

   Daughter insists that she knows he does it several times a day, and
that's surely too often?  Mum, very embaressed and knowing where this is
going, reads on.  She's certain Fran has no idea what she's getting herself
into by pushing this.  Alice does, and the thought that finally she's going
to have to go ahead with these things she's been afraid to for months is
making her weak in the knees.  And wet in the crotch.

   The manual states that for 15 yo boys, recommended frequency of emission
sessions is ideally and absolutely not more than once a week, and no less
than once per two months.  Further, that emissions must be personally
monitored by an adult guardian.  Induction should be via stimulation
provided by a female rather than self-masturbation by the subject male. 
Also, genital stimulation sufficient to induce erection and arousal but
without orgasm should be applied frequently at other times to exercise and
maximize erection quality and size, as this benefits penile growth
potential and ejaculate volume increase.  Erection induction, orgasm
blocking and other MPA functions may be used as adjuncts to the genital
exercise program.  Where feasible, the guardian may provide additional aids
to arousal in association with the emission and/or exercise sessions.

   There are further point form notes on the page, which she also reads
aloud.

   (See 'MPA User Manual' - Table of recommended emission session frequency
- Male - Footnotes.)





   Mum and daughter look at each other.  Mum is again thinking that if she
was to perform his 'frequent genital stimulation', she'd be sure to lose
control and permit him to orgasm the moment he insisted.  Then she'd be
sliding down a slope of failing resistance to anything else he might
demand. But if she orders her daughter to do it, she won't be tempted to
get out the remote and enable orgasms...

   She says to daughter "So you see what we have to do, if we're to stop
his naughty masturbation?  Well then, the genital stimulation will be your
job." Sister goes bright red.  She's looking at her brothers cock, which
has suddenly gone stone hard again.  He's looking back at his sister, no
longer looking at all shamefaced.  He's grinning as if he's won a lottery.
"But muuuuum!  I'm his sister!  You can't..." "And I'm his mother, and the
only adult here.  Aren't you listening to this?  This is the law now, and
it seems quite sensible.  Males have to regularly release their semen, and
the whole point of all this is to ensure he doesn't need to masturbate
himself to do that.  We're his family, so that means we have to do it.  As
his legal guardian I'll be doing his emission sessions, so it's your
responsibility to handle the exercises.  Now no more complaining, or
*you'll* get a spanking!

   Mum reads on, to the section that gives MPA remote command sequences to
control male erection, orgasm, ejaculation, wet dreams and masturbation. 
Fran gets terribly excited about the idea of making him have erections all
the time but disallowing everything else.  Mark is now glaring at her, his
stiff and still reddened cock bobbing with an irregular rythme.

   Alice reaches across him and pulls a couple of tissues from the box. 
She proceeds to wipe up the gobs of his cum from his stomach and chest, as
she says "Mark, I know Fran is right, and you've been masturbating twice or
more times a day recently.  Now we've all got MPAs to help us with these
out of control desires, only I've been reluctant to take action about your
habit.  I'm aware a healthy young boy like you feels a strong need, and
really does need an orgasm regularly to release the buildup.  I guess
that's why I didn't put a stop to this sooner.  But I'm afraid I'm going to
have to do something now, it's really getting to be too much.  Apart from
the moral harm of your frequent masturbation, everything I've read about
this indicates it's actually bad for your development to be doing this to
yourself.  I know it feels good, but that doesn't mean it is good for you."

   She wads up the sodden tissues and throws them in the bin.  Pulling
another one, she hesitates, about to take a major step.  There's a long
pause.  Then she takes a deep breath and reaches one hand to grasp his
stiff upright erection, using the other to wipe the remaining semen formed
in runs down his purpled glans and shaft.  There's still a line of the
perly fluid slowly seeping from the eye of his swollen glans.  He grunts
softly, tensing his bum as she pulls the skin down firmly to expose around
the flare of the glans, wiping the tissue around there as if pollishing a
knob.  She can feel his rigid shaft twitch, and imagines he could probably
come again fairly easily.

   "I'd like you to admit to me that you've been doing this way too often.
Twice a day, sometimes three of four times even!  There's no point denying
it, I want to hear you say you have, and that you should stop this.  Right
now."

   There's still more semen leaking from the tip of his cock, getting the
glans wet again whenever she stops wiping.  So she reaches a hand down
between his legs, to below his heavy testicles, and pressing a couple of
fingers against his urethra just above his anus, slides her fingers firmly
up across his scrotum, then up the bottom of his shaft, squeezing out the
fluids still remaining in his passage.  There's a swell of the sticky white
thick stuff from the opening of his dick, and she repeats her
knob-pollishing.  He grunts again, louder, his hips thrusting more openly
to slide his shaft through her fist that she has wrapped around it, midway
up the shaft.  She frowns, catching his eyes with what she hopes is a stern
expression.  But she doesn't remove her hand.  Can't.  He's thrusting
regularly now, and the feel of his inner firmness sliding through her fist
under the softness of his skin against her palm...  she's losing
concentration...  He's really quite thick, perhaps a slightly longer and
solid cock than her dear Thomas had.  Two years since Thomas died...  since
she's felt anything like this...  She shakes her head to clear the fog.

   "Mark!  Pay attention.  I asked you a question, and I want an answer! 
You don't need to be afraid, we'll take care of your needs.  You see..."
She waves her other hand at her fist still tight around the center of his
faster-thrusting cock.  "I know what you need, poor boy.  The pressure, the
need to spurt your stuff, I know it's very strong.  Even when you already
came so much just a moment ago.  But we're really going to have to get a
bit more control, aren't we?"

   She suddenly lets go of him, leaving him hunching his stiffness into
air, the member waving like an upside down pendulum.  He gasps, almost a
whine.  He looks at her face, wordlessly pleading.

   Folding her arms Alice contemplates him calmly back.  "Aren't we?" She
insists he speak.

   He bites his lip, barely able to resist grabbing his cock with his own
hands and continuing.  He was getting so close, the idea of fucking his
mother's hand, let alone the first time he'd fucked _any_ hand but his own,
had been such a powerful aphrodesiac.  He guesses the consequences of now
beating his own meat would be dire, so manages to resist.  Looks like he
can't get out of this confession.  Plus there's all that interesting
hinting that mom *and* sis would have to 'help' him...  Is that for real?
Only one way to find out.  But this is hard to say, in front of both mom
and sis.

   "Uh...  mom...  I guess...  I uh...  yeah, I have been...  umm...  ma...
masturbating too much.  S...sorry."

   "There, that wasn't so difficult, was it?  Good boy.  Now, just one more
thing." She reaches unfolds her arms and again grips his shaft, this time
working her fist up and down in a slow undulation.  "I want you to ask me
to take you under control.  I'm going to anyway, but it will make me feel a
lot better about it if you ask me.  And if I feel better about it I'm sure
I'll be a lot nicer.  You do want me to be nice to you, don't you?  I'd
hate to have to come down hard on your arse." She's still firmly stroking
him, now in time to his renewed thrusting.  "Go on, say it.  Say 'use the
MPA to control my urges and stop me masturbating'.  Say it...  say it..."

   As she ends she's shifting to hard, fast jerks down his shaft.  She can
tell he's near to coming, and again she stops, this time just loosening her
grip, letting his shaft slide lightly, frustratingly inside the tube of her
hand.  "Say it..."

   He moans.  "Unnnnhh!  Oh...  mum...  don't..." "Say it..." "Uhhhh... 
will you...?" "Say it!" "Mmmmmfff...  oh...  use the MPA to control my...
my urges, and stop me...  " He pauses, thrusting his cock hard up into her
loosely wrapped hand, as if in a last try at coming, and cheating her of
her deal.  But it's no good, not enough.  "...and stop me ... 
masturbating. OK?"

   "Thank you Mark.  I knew you'd do the right thing.  Now...." She grips
high tightly again, stroking.  "Would you like to cum now?"

   "Oh yeaahhh mom, oh, that's nice, yes, don't stop..."

   She slows down, loosening her grip again, teasing.  "But Mark, you just
came already a few minutes ago.  And I'm pretty sure that was at least the
second time today.  Three times yesterday I think wasn't it?  And about the
same the day before?  Now this is the point.  Did you listen to me reading
that stuff about emission intervals for fifteen year old boys?  Our
govenment says you should only come once a week at most, and they base that
on a lot of very careful medical research.  All that protein and vitamins
and stuff, your body is spurting out instead of using to grow big and
strong, and stretching out your glands so they get bigger and bigger and
can spurt a *lot* more when you do come.  Your poor penis too, look how red
it is, you've been masturbating so much you've nearly rubbed it raw.  Time
to give it a rest just now, don't you think?"

   She's doing a good job of pretending to be firm, but inside she's really
anything but.  She's a churning mess of conflicted feelings.  Firstly
there's the uncertainty she's always felt - a deep uneasiness about the
idea of denying her son's urges.  She knows that if he chose to push back
strongly now, she'd fold like an origami crane.  Then there's the problem
of her own frustrations - she's having to fight very hard against the heat
in her own sex, the primal urge to keep jerking her hand on his lovely
shaft till he spasms and pumps gouts of his seed under her stroking fingers
and out into the air as she watches.  She didn't get a good view of that as
she charged into the room as his dick pulsed and spurted earlier.  She
badly wants to see it happen again, in closeup, and feeling the waves burst
up inside his shaft under her fingertips.

   But the surprising, unexpected element of the mix, is finding she also
gets a dark thrill from the actual process of leading him into sexual
bondage.  Reading out the text of the DHM booklet, to Mark lying naked and
dripping semen on the bed, and Fran standing watching looking oh so aroused
and needy, had forced it home to her in a way she hadn't experienced when
reading the texts alone previously.  Reality.  Her own son, a virile, sexy
young man, literally entering into sexual thrall to her - total master of
his body's sexual functioning.  She would be managing his every sexual
action.  She'd be taking on the duty of regularly bringing him to orgasm.
She'd be directing her own daughter to service his sexual needs,
repeatedly, routinely, day after day.  She'd be doing all this while also
preventing her beautiful, highly sexed 17 year old daughter from ever
achieving orgasm, while having the girl engage in numerous incredibly sexy,
horny-making 'sexual exercises' for her son.  And all of this while her own
sexual pressure grows and grows, so many stimulations and no relief so long
as she can resist the temptation to disoby the morality laws, and allow
herself orgasms.  Which she's determined to do, since she doesn't believe
she actually deserves any relief, and...  has to admit to herself, that she
loves, *loves* this feelig of burning, hot, undiluted *need*.

   She could totally get used to this new role.  She plays it a little more
now, once more tightening her grip on his shaft then slowly, carefully
stroking him, watching and judging the signs of his nearing orgasm. 
"Still, I suppose one last one before we begin a propper schedule wouldn't
hurt.  You're so close aren't you?  It's amazing how quickly boys can
recharge, I bet you'd spurt even more this time than I wiped up.  What do
you think Fran, would you like to watch Mark spurting gobs of his thick
cream again?  You might not get another chance, even though you'll be
exercising this big stiff cock of his every day, he won't be cumming for
you.  I'll be...." She pauses suddenly, hand drawn back from his urgently
jerking cock.  "Oops.  You're right on the edge, aren't you Mark darling. I
can feel it.  But not just yet.  Hold it a bit longer." She runs a finger
tip feather-lightly up along the side of his cock, then tapping softly on
the straining swollen purpled head.  "Right on the edge...  can you just
*feel* that doing good, dear?  Look how big it is!  Feel how inside your
spoof is stretching the tight little sacks, such an urgency to spurt it
out. But while it stays in there it's doing you good, making you grow
bigger.  Do you enjoy the feeling, right there on the edge?  You know...  I
hope so, you're going to become very familiar with this feeling."

   She runs her hand up his abdomen, palm flat against his muscles tight in
his straining arch as he tenses motionless, hips thrust up in the air, arse
raised off the bed.  Straining, one cock-stroke away from exploding.  She
tickles him on the side of his chest, high up in his armpit.  It breaks his
almost-orgasm stasis, and he falls back limp on the bed, gasping.

   "As I was saying, I'll be draining your love juice once a week, making
sure you're satisfied *enough* but not too much.  I think Fran, that I
probably won't require your assistance with that.  Wouldn't want you to
develop an unheathy attraction to watching your own little brother spurt
his juices, would we?  How are we going there?"

   She grips his shaft again, motionless.  "My goodness Mark, it's *so*
hard!  You must be feeling like it's about to explode!  Look at this, I can
barely even bend it!  It's just beautiful how tightly swollen the head
gets, like its a ripe plum or something.  Here, I'll stroke it some more,
do you like that?  Mmmm, you do huh?  Just a little more...  come on,
that's it....  are you going to come for me darling?  One more stroke,
there...  now you're just dying aren't you?  Right...  on the tippy toe
edge...  and...  now I'm stopping again."

   She lets go again completely, picking up the MPA remote.  "Just a sec
Mark, I'm going to make some adjustments.  Now remember, no touching
yourself!  I'll get back to you in a moment."

   On the remote's screen she selects Mark's MPA from among the three, logs
in with her password, and enters the controls page for basic features.  She
ticks the checkboxes to block everything but erections since these are
recommended to be allowed.  The upload verify dialog takes only a moment
more, and it's done.  She switches to the page with bar diagrams for his
bodily functions, and smiles to herself.  As she expected his 'arousal' bar
is barely short of the 'orgasm' indicator.  Only now there's a red dashed
line surrounding the orgasm indicator, and a red word adjacent to it -
'BLOCKED'.  A few of the other bars now have BLOCKED flags too, but they
are not her concern just now.  OK...  moment of truth.

   She puts down the remote, and grabs his spasticly jerking cock again. 
He's apparently trying to boost himself over the edge by tensing his pc
muscle repeatedly.  Wasn't working.  She starts vigorously sliding her fist
up and down his member, gripping firmly.  He wails, in a tone of pleasure
and anticipation.  "Ohhhhhhh unnnnhhhhhhhh....  yessss......" His hips
thrust in counterpoint time to her hand, up as she pushes down...  She
smiles, watching his naked body tense in expectation.  She looks across at
Fran, who's standing close now, flushed and panting, her legs pressd
tightly together, hands clenching intermittently.  Another glance down at
the screen of the remote, and her smile widens.  Yes indeed, she is
definitely going to grow accustomed to this.  These two are in for a
surprise.

   Her fist is still gliding up and down the boy's stabbing rigid member.
There's a jerkiness developing in his hip movements, and he's not making
any sound at all now.  His face is screwed up in a tight grimace of effort.
She speaks to the girl in an idle tone, as if nothing much is happening.

   "Fran, after today I want you to assist Mark with the recommended
genital stimulation exercises whenever he requests them.  There's no set
limit on these, the documentation says a boy of his age should have them
whenever he feels the physical need, and for as long as he feels
comfortable to continue.  In a few moments I'll have you start with a
practice session, to get you started.  After Mark here realizes what's
going on now.  Poor boy.  I wonder how long it will take him?  Here, look
at this."

   She gestures at the remote unit's screen, drawing Fran's attention to
the 'arousal' bar.  Fran stares at it, open mouthed.  "Oh mum!  He's.... 
Oh.  Wow, that's...  "

   "So, so hot?  Yes, isn't it.  He still hasn't figured it out though. 
Still trying.  God, his dick feels so hard!  Here, you hold it.  Grip it
tightly, yeah, like that.  Don't worry, there's no way he can, you can pump
it hard if you want, or just let him try to fuck your fist hard enough. 
Isn't it awesome, you can feel his whole body vibrating like a bowstring.
Hmmm...  he really should take a breath soon, he's going to start turning
blue."

   At that point Mark exhales suddenly and takes another quick lungful of
air.  Then he's back to his singleminded attempt to fuck the heck out of
the fist wrapped around his shaft.  But you can tell from the way his
movements have become a succession of rapid bursts of hard thrusts with
intervening tentative slower movements and even pauses, that he has an
awareness of something not right.  This continues for a few more minutes,
then all of a sudden he goes limp, and opens his eyes.  He looks up at the
two faces above him, a questioning look in his eyes.  Then he looks down at
his still hugely erect cock and the enclosing hand, still stroking him.  He
doesn't seem to particularly care that it's his sister's hand rather than
his mother's.  There's a more important problem on his mind.

   "Unnnh!  That's...  uuuuhhhh!  you can't imagine uunnnoooooo what that
feels like.  It's...  uuuuh incredible.  Hard to describe, uhhhhh like I'm
way past the point I should have come, but it doesn't...  just doesn't...
what the fuck did you do to me, mum?  Ohhhhhh...  fuuuck, it doesn't
stop....  oooouhhhhh!"

   "I set your MPA to no orgasm, no ejaculation.  Few other things like no
wet dream too, but they're not your problem now.  See, look here." She
shows him the screen of the remote.  "See your arousal level is way up over
the usual orgasm threshold.  Intense, is it?  Don't worry, it's not
harmful. If you remove the stimulation it will fade back to normal.  I'm
not sure how quickly, apparently it's quite variable with different
individuals.  Let Fran know if you want her to stop.  You OK there Fran?"

   "Yeah, good.  His cock feels so nice, I could do this for hours!" "Well,
you might regret saying that eventually.  He probably will have you do it
for hours sometimes you know.  So, Mark.  Today is Friday.  You came
earlier, so lets set your schedule for friday evening relief times. 
Starting next Friday.  Fran will take care of you during the week, but no
cums other than on Fridays.  That's if you are good.  If there's any
trouble we can always switch to a longer interval.

   With the codes applied, mum 'tests' the operation.  She has him try to
touch his cock or balls - when he attempts anything other than a very light
unmoving two-fingered touch at the head, as required to direct his stream
when urinating, he jerks his hands away with a sharp 'Oww!'.  He describes
the feeling as like getting a strong electric shock in his fingers.  Yet
there isn't any corresponding sensation in his genitals, and his erection
remains unaffected.  The MPA very effectively identifies any kind of sexual
self-touching, and induces painful sensations into the appropriate branches
of his nervous system.  She has him experiment, and the MPA is quite
clever. No matter how he tries, he can't fool it.  No part of his body can
be used to stimulate himself.  Trying to use objects, such as a cloth
between his hand and penis, triggers the avoidance response very quickly.
Even thrusting his erection against the bedclothes soon induces a sensation
he describes like his penis is touching something unbearably hot and
spikey.

   She has him try this a few time, and other ideas like drawing a cloth
across his penis like a bowstring.  More 'Oww!', the MPA is very
discerning, almost as if it can read his mind.  Which in a way it can.  By
now his erection has almost completely softened, and they discover that
while his penis is soft he can touch it normally with no MPA response. 
Only when he squeezes himself a few times and starts to get hard again does
the 'no touch' effect reappear.

   Alice decides to move on to new tests.  "Well Fran, that seems to work
well.  Apparently Mark won't be playing with himself any more.  Now let's
see how it responds to stimulation by someone else.  Mark, lie back.  Fran,
just try holdng his penis.

   %%%% Has Fran try jacking him.  Works fine, he's hard in 2 seconds flat.
Uses the MPA to inhibit erections.  He goes soft like someone pulled a
plug. Alice has Fran strip, and pose infront of Mark.  Still no erection,
though he's paying very close attention.  Has Fran, still naked, suck him
with her mouth.  Fran refuses at first, till Alice gives her a sharp
spanking.  The girl is dripping wet, sex swollen and red.  Giving him head
still has no effect, no erection.  She lets him put his fingers in Fran and
play with the girl for a while.  Fran is panting and hunching desperately,
but he still has no erection.  Alice uses the remote to allow erection
again, and his cock springs to hardness instantly.  As a final test of his
orgasm block, Alice has Fran lie over him, sucking and jacking his rigid
cock while he fingers her cunt just above his face.  Both the teens become
wildly excited, humping at each other and nearly screaming with arousal. 
They both sound like they are on the very edge of cumming and work
franticly, desperately to reach release.  But it just doesn't happen. 
Alice is overcome herself, and steps back out into the hallway, to lean
against the wall and thrust both hands into her panties, frigging herself
like a madwoman.  Her own gasps of abandonment blend into the sounds from
the room of her son and daughter caught up in the passion of
not-quite-cumming sexual gale.  In a few moments she's at that point
herself, the months

   They leave him.  Mum is incredibly turned on, but goes and spys on
daughter - who she catches masturbating.  Mum throws a fit (frustrated
herself), brings in son, says "we've just been through all this!" and
grounds daughter, confined to house for a forthight.  Removes clothing
privelige.  Son gets solid erection again at sight of naked daughter.  Mum
has son spank naked daughter, then makes daughter practice masturbating
son. Says she should practice till she has it right for next Friday.  Also
to check that his orgasm block really works.  it does..  She orders
daughter to do that any time he wants - he says it feels very nice despite
not being able to cum.  It leaves him extremely swollen and hard.

   Result on daughter is also impressive.  She's panting, her sex swollen
wet and red.  She tries to head off to her bedroom, but mum says no, stay
here with your brother and keep him company.  I'm going to have a nap,
don't want to be disturbed.  She goes and masturbates for hours.  For the
rest of the week, son has an almost permanent erection, getting even more
urgent looking.  Mum decides to start taking measurements each day, which
gives her an excuse to handle his organ.  She seems to find a slight but
perceptible increase in size over just one week!  In the first few days he
has sister stroke him almost non-stop (to her great frustration), but
towards the end of the week he stops this, saying it makes the feeling of
pressure too uncomfortable.  Nonetheless, his erection remains, and springs
to fullest rigidity any time he sees naked sister.

   On Friday evening, mum calls them into the dining room at 8pm after
dinner.  She spreads a sheet on the dining table, and asks son to strip and
lie on his back on the sheet.  His cock is really hard and reddened.  it
looks like he's had sister pleasure him recently, and when mum asks he says
yes, he had her do it several times that afternoon because knowing he was
going to come soon made the pressure feel good, instead of unpleasant.  He
says it feels like he's going to explode if he doesn't get to empty himself
soon.  But he quite likes the feeling, so long as relief is soon.  Sister
says vindictively that mum should make him wait another week.  Or two.  Or
two months.  Mum finds the idea of tormenting him like that extremely
arousing, but knows she shouldn't do anything so extreme to him.  She
pretends to be angry with the girl for suggesting it, and as 'punishment'
orders her to next week, masturbate him at least four times a day every day
for the whole week.  She quotes from the manual, that his 'uncomfortably
full' feeling is beneficial, showing that his glandular reservoirs in the
prostate and vessicles are being enlarged by the secretions.  The manual
has a chart, showing gland percentage expansion rates over time given known
semen volume output, frequency of stimulation, and intervals between
ejaculations.  It is colour coded into bands of 'discomfort levels'.  It
gives her a strange thrill to see that '4x stim /day, 1 ejac/week' is coded
as the second discomfort level up on a scale of ten, if his output is
average.  She decides to measure his volume tonight.  The idea of
increasing his 'discomfort level' in future is clearly going to stick in
her mind.

   She has sister begin masturbating him now, while mum goes and gets a
measuring cylinder big enough to fit over the head of his penis.  Her own
permanent orgasm block makes her want to see him squirm a little too,
before he gets his relief.  This whole business of females forcing a male
to do sexual things seems really wrong to her, but somehow because of that,
it's deeply exciting.  Again the thought crosses her mind that if she had a
man in charge of her, he'd at least someties be allowing her orgasms.  She
wonders what her son would do to her, if he was in charge.  This *really*
makes her shivver with desire.  A 15 yo boy, totally controling his
mother's sex...  And his horny, naughty, sassy sister too, she thinks. 
God, that turns her on even more.

   She takes her time in the kitchen.  When she returns, he's panting and
groaning, thrusting his loins upwards vigorously to drive his rigid,
reddened prick into his naked sister's two handed grip around the shaft. 
The girl's own sex is swollen spectacularly, dripping fluids down her
thighs and with a hard little clitoris sticking out a couple of cm at the
top of her slit.  The idea of having the girl sit herself on his cock goes
through her mind, but she dismisses it.  She does wonder though.  Both
hugely turned on, neither able to cum...  Perhaps if they are both very
very naughty some day...  Or she is....  the idea of his rigid, cum-blocked
cock thrusting in her own heated cum-blocked vagina..  ahhh....god, it
could be hours and hours of sweet torture!  Do some horny single mothers do
that with their young sons, too young to assume the manhood of the
household and so control the mother?

   She picks up the remote and the manual, looking up the commands to
enable orgasm and ejaculation.  Wait a minute...  why are there two
different commands, she thinks.  Is one possible without the other?  She
reads footnotes, and finds that indeed it is, with the MPA's detailed
direct control of sexual nerves and muscles, and linkage to the brain
center involved in orgasm.  But it isn't recommended as prolonged use like
that can have 'imbalancing' effects on natural reflexes.  Mostly used for
specific purposes in correctional facilities.

   Her daughter is still pumping his rigid member, as he moans and thrusts
back at her.  Mum tells daughter to stop now.  She does, reluctantly, then
seems to be suddenly struck by the intensity of her own arousal.  Her hands
fly to her sex, and she stands bent forward, clutching at herself,
shuddering, working her fingers in her slit.  Mum strides across and gives
her a sound spank on her bum.  "Fran!  Stop that" Oh mum!  It's so strong,
I can't help it!  It's not fair, all men get to have orgasms and single
girls don't!"

   "Now Fran!  You know that desire is really a pleasurable feeling for
girls.  Strong yes, but not a torment.  It makes us desire men, and want to
be kind to them, which is why nature makes us feel that way.  For men it's
different.  For them desire builds up into a truly painful, unbearable urge
as their fluids accumulate.  In small amounts it makes them loving, in
large amounts it turns them into desperate violence-prone beasts.  It's our
duty as females to prevent that, if we want to have loving men in our
lives. In a way this is their burden, programmed in by evolution as a last
ditch drive to ensure men will do _anything_ to ensure the perpetuation of
the species.  Which means that in situations where relief is impossible,
they will suffer terribly.

   She puts a hand on his still thrusting stomach.  "How's that pressure
now, dear?  Did Naughty Fran make it worse?  He grunts.  "Mum, this once a
week thing is going to be bearable.  Interesting.  I've never felt like
this before!  But it's scary - I really can't imagine what it would be like
with longer intervals.  God!  I thought it was bad before, but after Fran
did that now, it feels like there's something inside so desperate to get
out that I'd go crazy with much more of this.  Oh god, god I need to cum so
bad!"

   She smiles down at him.  "Poor, poor dear.  But you know, I've been
watching Fran do this for you all week, and I have't had a chance to
practice it myself.  You have such a lovely, big, hard cock.  Look how
swollen and purple the head is!  My dear boy, you are going to make some
girl so very happy some day.  Already so big and you are only 15!  I can
see why this MPA stuff is organised to make cocks grow bigger.  Wow, if you
grow much bigger than this you are really going to make the girls scream in
joy when you shove your monster cock inside them.  Wouldn't you like that
dear?  Don't you think that's worth some discomfort now and then?"

   She grips the rigid shaft and starts jacking her hands up and down. 
"Wouldn't you like to really stretch the girls and make them scream?  At
your age, just a year or two of effort can really enlarge it, they say." By
nows she's vigorously working his cock.  She can't believe how good it
feels in her hands, or how sparks fly from it into her crotch.  No wonder
Fran...  She look aside at the girl, and realises she is standing with her
legs tightly crossed, squeezing her thighs together rythmically as she
watches her mum masturbate her little brother's cock.  Alice snaps at her
"Fran!  legs apart please!  Come over here and pay close attention.

   Alice puts in a long session of jerking his cock, using all the tricks
she knows, teaching them to Fran.  She continues for several hours,
alternating between herself, Fran, and giving him short breaks to recover.
By 11pm he's almost whimpering in desperation to come.  His cock is still
rock hard and pulsing with his desire,



   %%%%%%







   One day, after such a session, in a heated daze of her own fantasies and
sexual frustration, she calls son into daughter's bedroom and tells son
that she (mum) can't seem to deal with daughter's naughtiness, and he
should try.  She reminds him that the whole point of the MPA program,
according to the published documents, is to prevent the sin of female
masturbation and excess sexuality.  She gives him the remote, and then also
the girl's bedroom key.  She mentions that she's lost her own key, which
was the same as daughter's.  So now he has the only two in the house, for
all the bedrooms.  She gets carried away, and says pretty plainly that
daughter isn't the only female around here that needs some discipline.  The
act of giving him the remote, and saying these things turns her on
extremely, so much that it's completely obvious, and it's obvious that it's
obvious to him.  She gets so flustered she has to flee to her bedroom,
where she's unable to stop herself stripping and masturbating wildly and
noisily on the bed.  The thought of him having the remote, and being able
to literally control her sexuality, and also her being unable to lock her
door, inflames her.  Then she wonders if using the remote it's possible to
actually tell when someone is masturbating?  (It is.)

   Suddenly she feels a change - her vagina starts powerful rythmic
clamping contractions that she can't change at all.  She's rubbing her
aching clit franticly, and sticks a finger inside herself, the feel of her
contractions against her finger driving her so hard that she's sure she's
finally going to cum at any moment.  But she still can't quite...  she
completely loses herself, moaning and threshing, desperate to cum.  Knowing
her son has used the remote to cause these contractions just makes it
worse.

   She barely hears the door open.  Son walks in, pulling daughter by the
wrist.  Daughter is gasping and panting too, and he proceeds to strip her,
while she's too aroused to put up more than feeble protests.  Eventually
daughter is sprawled naked on the floor, writhing, apparently having
similar vaginal contractions judging by the way her pouting cunt pulsates.
But now she doesn't seem to be able to touch her sex with her hands at all.

   Mark speaks to Alice: "That's interesting mum.  I see here in the logs
you've been masturbating several times a day, pretty much since we got our
MPAs done.  Mostly at the same time or right after Fran was masturbating."

   (Logs?  She didn't know there were logs.  Oh God, did he figure out she
masturbated after seeing his erections?)

   "You weren't kidding about both of you needing discipline!  Well anyway,
I think you should stop now." He enters some commands on the remote, and
suddenly Alice's fingers HURT where they touch her sex.  She pulls them
away as if burnt, and wails in her frustration.  Her pussy is still
pulsating.

   "That's better.  No more of that naughtiness for you or Fran from now
on, unless I say so.  No, don't get up.  Just stay lying there.  It's going
to take a while to learn how to use this thing.  Hmmmm...  that cunt muscle
exercise seems to be working good."

   He pulls a couple of jumbo size permanent markers from his pocket.  "I
read you're supposed to exercise those muscles every day, won't that be
fun? We'll get you something better than these to work with later, but for
now..." Sitting on the bed, he unceremoniously shoves one of the makers
deep into her cunt.  Still holding the end sticking out, he enjoys feeling
it jerk with her contractions, a big grin on his face.  Having the fat
cylinder inside intensifies the feeling of the contractions for her, so
much that she cannot help groaning sexily with each one.  "It's fun to
watch, that's for sure!  And now for Sis." He kneels down beside Fran, and
inserts the other marker in her pussy.  It seems to take a bit more effort
to force it in, and she yells in pleasure/pain as he twists it back and
forth, working it deeper.  Once only the cap is showing, he lets go but it
promptly starts sliding out again.  He stands up, with his shoe against it.
Starts stripping of fhis own clothes.

   Naked, his erection pops up and slaps against his stomach, hard as a
rock, bigger than the markers.  He sits down on the bed gain, bare toes
pressing the marker back into Fran, his left hand holding the marker in
Alice, right hand the MPA remote.  They are both still grunting and moaning
with each contraction, but slightly out of phase and frequency.  "OK, let's
try...  a bit of reflected induction." He thumbs away at the keys for a
couple of minutes, frowning.  "It's great all this command syntax is on the
net, but I've never had an actual remote to play with, just a simulator
running in Mame.  Umm...  this should..." Suddenly Alice feels the rate of
her cunt's contractions alter, as well as a number of other curious things
happening down there.  The first other difference she notices is that where
she was doing the frustrated thrusting of her hips, and desperate
tightening of her stomach muscles in an apparently futile struggle to reach
orgasm, now those seem to be imposed upon her beyond her will to affect. 
Just like the vaginal contractions.  If anything, the sensory effect is
even more overwhelming.  Her clit suddenly feels like it grew even harder,
and each contraction feels as if her pussy will rip loose of it's moorings.
She cries out with each one "Awwwwhhh!  Awwwwhhh!  Awwwuugh!  Awuunnhh!" It
takes her a while to realise through the haze that there's a kind of
leading echo to her moans.  Fran's cries are exactly matching hers, if
slightly preceeding her own.

   Mark chortles in glee.  "Yay!  It works!  Cool, I like this, you're
perfectly synched!  Your pussy is clamping exactly in time with hers!  This
scripting stuff is really neat!  OK mum, I'm going to leave that one
running.  It makes a lot of your body do just about exactly what Fran's
does, whenever she's turned on.  Same muscle contractions, same arousal,
and so on.  You'll get mostly her sex-sensations when they are strong, as
they'll override yours.  I guess that might be a bit confusing, but should
be OK.  If she cums, you will too.  Not that I plan to let her.  Does your
pussy feel really tight like hers now?  Feel this?"

   He lets go of the marker in her pussy, while shoving the marker in and
out of Fran's pussy with his big and first toe gripping the cap.  She lifts
her head and stares slack-jawed in sexual drunkenness, as the marker in her
pussy moves only with her own contractions, while she can FEEL it thrusting
firmly in and out of her pussy.  She looks over the side of the bed, and
watches the pen pistoning in Fran's cunt, exactly as she can feel it move
in hers.  Even her own hips are hunching in lockstep with her daughter's.
The feeling is...  indescribeably arousing.  To be so suddenly and totally
a plaything, a helpless, managed sex toy...  Her brain explodes in
fireworks of sexual confusion, humiliation, acceptance, joy...

   "Or how about this?" He slips down to kneel on the floor again, and
slides his fingers in Fran's slit, wetting them with her juices.  Then
centers on her erected clit, strumming it rapidly and firmly.  Both of the
females immediately scream with the intensity, forming a strange
counterpoint of two different voices, making different sex-cries, but as if
from the same strike aganst their most sensitive treasure.

   Alice: "WaaauuuUUUUUUUHHHHHHHHHGGGGG!"

   Fran: "OoooooooooohhhhhhhuuuuuuoooO!"

   Mark: "Beautiful.  Kinda sad it will only work within about 30 meters,
in MPA radio range, but I guess it'll do."
He lets go of Fran's clit and stands up.  He grips his erection and
strokes it several times, admiring the view of the two beautiful females,
both writhing on their backs in heat, a waggling marker protruding from
each cunt, breasts bobbing in near unison with their lockstep heavy

breathing.  "OK, let's rearrange here.  Sorry mum, I want you to lie on the
floor.  Fran, get up here on the bed." Neither one makes much of a move,
and he raises his hand as if to slap Alice on her thigh.  Then thinks
better of it, and bending down, slaps Fran on her inner thigh.  Both women
gasp, and open their eyes wide, looking at him in surprise.  "Heh.  Half
the work.  Come on, move it.  Swap over." He gives Fran another lighter
slap, and both girls flinch, but get moving grogilly.  Alice makes the
mistake of sitting up first, which drives the pen all the way into her. 
She barely seems to notice.  Then Fran does the same on the floor, and they
both gasp in unison, tilting onto their right buttock to allow the pens to
slip back out somewhat.  Both of them stand up, and the pens begin to slide
slowly out.  Both of them have a persistent pelvic twitch, short sharp
pubic thrusts, at the same tempo as their vagina muscles still carry on the
'exercise program'.

   "I want both of you kneeling, arse in the air, head and shoulders down.
Fran, up on the bed."

   They shuffle through the motions, with Alice seeming to have a lot more
trouble coordinating herself than Fran.  Parts of her lower body keep
twitching in identical motions to Fran's, which don't suit her own
position. She stumbles slightly as Fran steps up onto the bed, but
recovers. Mark watches her interestedly.  Once she is kneeling he pushes
her shoulders down as close to the floor as she can go, and taps her inner
thighs to make her spread her legs wider.  The half-out but still twitching
marker is now pointing near vertically from her up-thrust sex.  He pushes
it back, all the way in till it entirely disappears, then lets go.  Watches
as it rebounds a little, peeking the black plastic cap back out between her
lips.  It still jerks.

   "Heh.  I just had a nasty idea.  I wasn't going to let either of you
naughty girls come, not for a long while.  But this mirroring setup is
funny.  I wonder if anyone has ever tried this before?  I was thinking it
was time to finally fuck Sis here, and have you both feel it, but still
leave your orgasms completely disabled.  But it just came to me...  I can
leave _yours_ disabled, but allow Sis to come.  That means you'll feel
exactly what she feels, have all the contractions she does, you'll kind of
feel her cumming as if you were, but _you_ won't get the orgasm release. 
Isn't that neat!  I bet it's going to drive you completely crazy."

   He turns to Fran and pulls the marker from her pussy.  Then he
hesitates, and pushes it back in, and out, working it back and forth in
her, while glancing sidelong at Alice's butt sticking in the air.  Both
girls are panting and moaning heavily, still in more or less unison.  "Mum,
it's nice you're not complaining about any of this.  I'd have expected you
to be begging me to stop, or let you cum, or I shouldn't be doing this to
my mum, or something.  I'm starting to think you really want me to do all
this.  Not that I'd pay any attention.  You know with the laws now, this is
actually all fairly legal?  I may be a minor, but I'm still arguably the
man of the household.  Before you gave me the remote, it was a bit gray,
but since you *did* formally give it to me...  I'm _responsible_ for your
sexual management, and it's OK for that to include my own pleasures, and
anything I want so long as you're not harmed.  That's what it says.  Both
of you."

   He continues to work the marker in his sister's tight pussy, marvelling
at the feel of forcing it in against her regular muscular contractions,
enjoying how the thrusts make her moan and hunch her gorgeous butt back
against his push, and how his mum's equally sexy behind thrusts much the
same.  Her moans in time too.  Two for one!

   "I'm guessing both of you are just too drunk on sex hormones at the
moment to think much.  Sis, I thought you'd have been spitting nails.  But
instead you're just dripping girl juice and pushing back, even more than
good 'ol mum there.  Must be pretty desperate for it, huh?  These MPA
things sure are fantastic.  So right...  stop women from cumming whenever
they feel like it, and the whole world turns into a much better place. 
Turn off your ovulation, and you're safe to fuck anytime.  Turn off your
cums, and you're eager to fuck anytime.  Pure genius!  Fifteen years old,
and got my cute-arse sister and horny mum for sex anytime.  Isn't America
fucking fantastic!?"

   He pauses, pulling the marker completely from her and dropping it on the
bed.  Picking up the Remote again, he types for a few moments.  Suddenly
the regular vaginal contractions stop, replaced by a kind of twitchy
tension, as if the muscles want to clamp but are waiting for something.  It
feels as if she's horribly empty, unfilled.  "OK, don't answer that.  Now
there you go Sis.  We'll have a talk later when you _can_ talk, about when
you deserve to cum, and how much you want to and what you'll do for it. 
For now...  you're on triggered cum.  Same as before, you can't.  Except
while I press a button here, you're allowed to.  Isn't that nice?" He
presses one of the buttons, holding it down for a about three seconds then
releasing it.  For those moments Fran had felt like some monsterous storm
cloud was drawing together all the tensions in her belly, rippling with
lightning and menace.  Something...  going...  to....  And then as suddenly
it seemed to disperse, levelling back out to the merely insufferable
frustration she'd been feeling...  well for months now.  She wails,
descending to sobbing.  So desperate she forgets and lifts a hand to her
sex - and gives a short Eeeee!  as the masturbation prohibition jolts her
with a sharp burst of very unpleasant sensation.  Her hand drops back to
the bed, clenching sheets in a bunch.  Alice had given a very similar jerk
of her body and grunt as Fran hit her limiter.

   "Whup!  You missed your chance there.  Well, I'll probably give you
another chance later.  Be good now.  Oh, and mum, if you can hear me at
all, later we're going to have a very long talk about what exactly your sex
life is going to be from now on, and why I'm going to enjoy the heck out of
never, ever letting you come.  Except in possibly a very few cases which
are so improbable I can barely imagine them.  Despite that with this I can
imagine _plenty_." He waves the Remote around to illustrate.

   "Well, too much talk." Taking up a kneeling position behind Fran's
upturned buns, he presses down his rock-hard cock to line up with Fran's
splayed slit.  He'd already slid the forskin back when stroking it before,
and now the purple swollen glans presses in between her damp, puffy labia.
He pauses there.

   "Hmmm...  wait, this is such a historic moment..." He hops back off the
bed and goes over to Alice's desk.  Opening a drawer, he picks out her
digital camera.  Back on the bed, he takes the same position, but holding
the camera to his eye, framing the shot.  "Definitely something to preserve
for posterior.  Ha ha!  Posterior - yours.  Getting fucked for the first
time." He takes several shots, holding he camera at different angles, all
with the head of his rigid cock pressed just far enough into her sex to
prevent it springing back up to vertical.

   He grabs the shaft again, swiping the head up and down her slit
repeatedly, concentrating on rubbing her erect clit.  "In some other time,
I'd be playing nice guy and seeing how many times I could make you come
before I did.  And after.  But that's not today, hey?" He keeps wiping her
clit, glancing towards Alice's arse waving in the air.  There's clearly a
lot of sensory connection going on, as she shudders and pushes back on thin
air at each of his swipes of Fran's love button.

   "Mmmm...  feels so nice to me.  Damn, I could almost cum already, I....
hmm" He pauses _again_, and swaps the camera for the remote.  A few
moment's consideration, and a bit of typing.  "Silly me.  We got the tools,
why not use them?  Correction, I'm absolutely not going to cum until I
decide I want to.  Oh this just gets better and better!  OK, where were we?
Oh yeah, first fuck of Fran, Take 1." With the camera again, he switches to
video.  Pans around taking in Alice on the floor and Fran on the bed, then
zooms in on his cock, as he sloooowwwly presses it entirely into Fran. 
He's quite a bit fatter than the pen, and longer too.  Fran moans loudly in
pleasure as he fills her, satisfying that empty-achy feeling.  His cock is
warm and hard-fleshy-ridged, unlike the cold, smooth marker pen.  She can
feel the larger head deepest within her.  His thighs come to rest against
her bottom and back of her legs, making her feel surrounded, warmly
enfolded.  She can feel his stiff organ throbbing with his heartbeat within
her.  It's at once the most fulfilling thing she's ever felt, and the most
frustrating.  It reminds her with razor edges how badly she wants to come,
how desperate she has become for an orgasm in the past months with none. 
Her body quivvers, shaking, urgent in need to rut hard on that shaft, make
it thrust in and out of her sex violently, instinct certain she could
achieve orgasm on *this*.

   But he has his hands pressed firmly around her arse cheeks, holding her
still.  He clearly wants to savour the moment.  She may be half out of her
mind with urgency, but she knows he won't let her cum at all if she doesn't
follow his lead.  Shivvering, she does her best to hold still, despite the
storm blowing through her body.  She can feel that twitchy tension in her
cunt growing, growing, nothing she can do to fight it.  Will he be annoyed
if her pussy clamps tight on him?  She doesn't know, wants to play safe. 
She tries to fight it, hopelessly.  The tension builds, unbearable...

   Meanwhile, on the floor Alice is having a rather different experience.
The regular clamping of her sex had ceased when Fran's cunt stopped its
'exercise' spasming.  She'd felt the same replacement feeling of itchy,
needing emptiness, only overlayed on the sensation of the marker pen still
within her sheath.  A strangely contradictory feeling, and one that had her
trying to clamp down on the pen to relieve.  With almost no success at all.
She'f felt Fran's 'brief cum-ban removal' intensely, but with a very
strange effect.  She'd felt the intense buildup and desire for relief, but
with zero sensation of actually being possibly able to cum.  The result
being that the feeling didn't seem to dissipate at all, just hung there
ominous and brooding of delerious torments withing her belly.  She'd been
free to throw her hips around in desperation, and had.  Gasping, out of
breath and virtually in tears from the impossibility of such torment.

   Then Mark's rapid stimulation of Fran's clit had hit her own clit
something like an excitement hammer.  She'd gasped, writhing under the
onslaught, drumming her feet on the floor in a frenzy.  Her poor pussy,
cruelly reminded of the pleasures of penetration by an unmoving metal
cylinder, and then...  the sensation of a cock's fat head pressing against
her labia, promising entry, promising glorious penetration to her depths.
Only that delayed, teased, withheld.  She sobbed in near delerium, waving
her buttocks in the air, pleading for someone, anyone, please please won't
you think of my poor abandoned starving child cunt?

   Then almost unexpectedly, the cock returned, and slid ghost-sex-like
deep into her.  The cock amd the marker, both within, both teasing her with
immobility.  Two years, nearly three!  It's been that long since she was
fucked!  Months since she came.  Come ON!  Her body screams for the old
familiar, long denied ecstatic pleasure.  It MUST have it!  MUST!  She goes
wild, gasping incoherently, throwing her butt around in the air as if
somewhere, somehow, she can connect it with a moving, pounding cock.  But
there's nothing.

   Mark speaks to Fran, though aware he's really just musing to himself. 
"Oh wow, looks like this idea is going to work out really well.  Heh.  It
might even be funny to let you masturbate *and* come, whenever you want,
just to make mum's life difficult.  Or maybe make her fool around with you,
making you come over and over, but all she gets to feel is the buildup and
*your* cum, but not her cum.
