Measuring My Cum

My problem started soon after I had just turned 18. My
name is Jacob and I'm just a regular kind of guy. Or so
I thought. Ok, so I had a few issues back then, but
doesn't everyone at 18? For me most of these issues
revolved around my mom being temperamental and
difficult, and the way I had been brought up.

My mom, Margaret Addington, or Marge as she liked to be
known, had divorced three years back, and now at 55, in
the prime of her life, she had become a bit of a
recluse. She'd given up on men, 'I'm not giving myself
to another man' she would say angrily, when I'd suggest
she maybe try meeting someone. 'Not after all the
trouble your father gave me' she would continue. 'One
man in my life has been quite enough'.

My mom had a tough life until she divorced. She'd
married quite late compared to others in her generation
at 35, been my father's second wife and it seemed he'd
only married her to have someone cook and clean and
provide some carnal satisfaction. They had argued a lot
- as far back as I could remember, and enough for me to
get sick of it.

Anyway, it all finally ended with a divorce and with me
as an only c***d. And now mom just wanted to stick to
working in her job of many years as a librarian until
she retired, enjoying her garden, and the occasional
women's institute gathering, a few female friends and of
course taking care of her only precious c***d -- yours
truly.

The problem for me in all of this was that I had been
over protected, and mom had a fiery temper, and would be
very controlling. She was also quite prudish and
straight laced. Now, at the age of 18 when I just wanted
to break free and experience life, I felt guilty about
leaving her alone. We had no other family close by, so I
felt obliged to stay on at home and go to my local
college rather than move away. And that meant losing my
freedom, and having to cope with mom's controlling ways,
and her moodiness and temperament.

This was not easy. Sometimes she would fly off the
handle over the smallest thing. I'd argue back and then
she'd sulk or not talk to me for ages until I came round
to her way of thinking. And mostly, I would give in. I
wanted a quiet life. It was either that, or the guilt I
would feel by moving out. So I decided to stay. Looking
back, I think that was a mistake in some ways, but as
this story unfolds, you might think otherwise.

Before I go on, some descriptions. I was 5'8" average to
heavy build with dark hair, and I wore glasses. I didn't
think I was bad looking, but I had never really made it
with girls up to then, and never had a girlfriend. I was
still a virgin at that stage.

Mom at 55, was 5'6", with dark hair, which she liked to
keep in a bun, and a dress size of between 12 and 14.
She had filled out, so to speak, as many women do in
their late forties and fifties, but she did still have
curves and a figure of sorts. She had quite a voluptuous
frame with largish boobs that definitely filled out
anything she wore (I found out later she was a size
38DD), and a good-sized rear end -- not gross, but quite
a nice full, curvy bottom.

And if you were going to ask me 'Did I ever fantasize
about my mom sexually?' my answer would be yes, of
course. Many a time. Don't most sons' at one time or
another? This story is actually about how those
fantasies, quite unexpectedly became a reality.

So back to the story. I had just turned 18. Like most
guys I had been masturbating for some years. I had what
I thought was a reasonable stash of porn -- magazines,
videos and DVDs. Then for some inexplicable reason I
started to develop a regular ache in my balls which I
had never experienced before. It would start gradually
in the mornings and then build up to an uncomfortable
feeling by the end of the day.

The only way to relieve the discomfort would be to bring
myself off and get rid of my cum when I got home in the
evenings. I'd have to do it at least three times during
the course of the evening. By the end of my third wank,
I'd be fine and comfortable again. And the funny thing
about this was I always seemed to have plenty of semen.

I never seemed to dry up or produce a small quantity,
even after the third time of the evening. After a few
weeks of this I decided I needed to get some medical
advice. There was surely something not quite right.

I felt embarrassed about going to our family doctor. I
had never really discussed anything sexual with mom
before (as I said before, she was quite a prude and
didn't approve of 'modern girls' behaviour), but I felt
as this was a health issue, I should ask her advice on
it. I didn't know who else to turn to, in all honesty --
I didn't really want to discuss it with my friends.

One evening after our dinner we were in the living room.
I was reading a magazine and Mom was knitting (I was
only allowed a TV in my room as mom rarely watched TV,
refusing to have 'those awful shameless programmes with
semi nudity and v******e mixed with commercials ' in her
living room).

"Mom, I've got a bit of a problem," I said.

"What's that dear?" she said, not looking up at me.

"Well," I replied rather awkwardly, "It's a little
embarrassing."

"Come on Jacob, speak up," she replied rather sternly
this time, and giving me a cursory glance.

"Well, it's a little personal," I continued again,
hesitatingly.

She stopped her knitting, straightened up her body a
little and looked at me rather seriously. "Tell me young
man," she said keenly, "Have you got a girl in trouble?"

"Err... no mom," I replied. "It's more of a personal
health thing."

"Go on then," she said relaxing a little and starting up
her knitting again. "Don't be shy."

"Err... well it's about my... err," I hesitated,
"...private parts," I said squirmingly, and in a low
tone.

"About what?" she said loudly.

"Well, it's about my testicles," I said not looking at
her but the carpet in front of the sofa.

She stopped knitting again.

"Go on" she said, more gently than I had expected.

"Well, I seem to have some aches and discomfort there. I
was wondering if I should se a doctor."

"Are you sure you've not been with a girl and caught
something?" she replied accusingly.

"No mom, honestly," I said.

She thought for a moment. "How long has this been going
on?"

"A few weeks," I said.

"A few weeks?" she replied questioningly. "Why didn't
you say anything before?"

"I was embarrassed. And I thought it might clear up by
itself."

"Oh," she said, looking concerned. "Well, I'm not sure
what I can do except get you in front of a doctor. I'm
not too keen on you seeing our family doctor Jacob
because our health center is full of gossips and I
wouldn't want my son to be thought of in a funny way --
they'll probably think you've caught something off
someone."

I felt a bit horrified that mom would think like that,
but I could sort of see her point.

"I'll have to take you to a private clinic," she said
after another pause.

***

Two days later we were both sitting in the reception of
a private sexual health clinic. Don't ask me how mom
found out about it, but she had been busy making phone
calls after I raised my little problem.

We went in to see the doctor together. As we entered the
consulting room I saw a desk behind which a largish
looking lady in a white coat was sitting. There were two
chairs in front of the desk and to one side of the room
a standalone curtain rail on castors, behind which was
an examination table. Mom and I both sat down on the
chairs.

The doctor was a mature lady -- she looked liked she was
around 50, chubby and buxom, and with greying hair. She
wore glasses, but had quite a pretty face and wonderful
deep blue eyes.

She looked at mom and then me, smiled and then said in a
quite matter of fact way, "Hello. My name is Dr Taylor.
It's Jacob isn't it?" she said, looking directly at me.
I nodded.

"Your mother contacted us about a problem you are
having," she continued. "I know you are 18, and old
enough to see me on your own, but she wanted to sit in
on our little consultation." She briefly glanced
reassuringly at mom and then back at me. "Is that ok
with you Jacob?"

"Err, yes, sure... I guess," I replied, a bit timidly.

"Now, what appears to be the problem young man?" she
continued.

I explained the problem like I had to mom previously,
only with more embarrassment. The doctor listened
patiently and took some notes as I spoke.

"As you are just a young man, there could be many
reasons for your condition," she said looking at me then
at mom. She spoke quite confidently and without any
embarrassment. I guess she dealt with sexual problems
all the time.

"It may just be a phase and nothing to be too concerned
about, but we do need to do some tests," she continued.

"Firstly, I need to examine you," she said. "Come over
to the examination table."

I had been expecting this with a bit of trepidation.

I went over to the table and lay on it. "Undo your
trouser button and belt," she said, as she drew the
curtain rail around us so mom could not see.

I had undone my belt and top button of my jeans and
lowered the zip a little. She put on some latex medical
gloves which were cream coloured and tight fitting on
her hands, and pulled down my jeans and underwear in one
yank, as I moved my hips up to help clear the way for
the material.

I was exposed from the waist down, my private parts
showing.

"Just relax," she said.

I felt her hands first touch and lift my limp cock,
squeeze it gently along its length, and then feel around
my balls, cupping each in turn. Then she pulled back the
foreskin of my penis for a moment, taking a look at the
skin there, and then let it go back to normal.

"Any pain when I touch your penis or testicles?" she
said, looking at me for a moment.

"No" I replied. But I do still have a sort of ache in my
ba... I mean testicles," I said. It goes away when I...
err... you know.. .masturbate," I said meekly.

"I see," she said, still looking at me and then licked
her lips. She seemed to linger her tongue around and
outside her lips a little longer than I would have
expected. Or maybe that was my imagination.

"Ok, Jacob" she said finally, "Get you clothes back on
and come back to the desk when you are ready. She took
off her gloves, apparently satisfied, washed her hands
in a sink next to the table, and walked around the
curtain back to her desk.

I made myself decent and joined her and mom a moment
later. I was still thinking about the way she had licked
her lips.

"Well," said Dr Taylor, "Everything appears normal on
the physical examination. What we need to do in a case
like this is take some blood tests and samples of your
semen."

"Ok," I said, rather timidly. Dr Taylor then looked at
mom and said firmly, "Mrs. Addington, I assume you are
happy to go ahead with the tests?"

"Yes, of course" replied mom.

"Good. Now, I'm going to ask you a few questions Jacob,"
said Dr Taylor looking back at me. "Don't be
embarrassed. Firstly, do you have a regular girlfriend
at the moment or have had one in the past year?"

"No," I replied.

"Have you been with a prostitute in the past year?"

"No," I replied.

"Have you had casual sex with anyone in the past year?"

"No," I replied.

Dr Taylor ticked some boxes on a form as I gave my
answers.

"Right," she continued, "As I mentioned before, this is
not something to be embarrassed about -- it could just
be a phase you are going through as many young men do at
or around puberty. Some boys develop later than others
and everyone can have slightly different experiences."

"For the blood test please see the nurse outside, who
will take some samples, and I will let you know the
results of those in one week."

"Now, the other thing is samples of your semen. As you
are describing an unusual amount in quantity, what I
need from you is a record of how much you are
producing." She looked at mom and then me.

"Now, it is very important that we get an accurate
record as possible. So what I need you to do is use
this."

She opened a drawer of her desk and pulled out what
looked like a clear plastic beaker, about 5 inches in
height and 3 inches wide at the open end, and with some
measuring lines on the side.

"It's better that you don't use a condom to masturbate
into as much of your semen will get stuck to the insides
of it and so we will lose the accuracy of the
measurement. This beaker has been specially treated on
the inside so that all the semen flows to the bottom and
then you can take a measurement using the lines on the
side," she continued.

She looked at mom again and then me, making sure we
understood. "Is that ok?"

"Err, yes," I said, and mom said the same.

"Now, Jacob, when you masturbate you need to aim the tip
of your penis at the centre of the beaker and make sure
your cum goes into the beaker. Make sure you don't spill
any. After every session of masturbation, measure the
amount produced and write it down on this form." She
gave me a couple of sheets of paper with grid lines on
and columns marked 'date', 'time' and 'quantity'.

"In order to get an accurate sample, I need to know how
much semen you are producing everyday for 2 weeks. I
will arrange an appointment to see you again in 2 weeks
time, and depending on the results, I may ask you to
continue to keep a record of how much semen you are
producing for a further two weeks after that. Is that
clear?"

Mom and I both nodded.

"Now one last thing, is that when we ask for samples
like this, we normally find from experience that most
men require the help of their partner, girlfriend or
wife in collecting the samples, because it can be quite
awkward for a man to catch all his semen when he
masturbates into this beaker. In this case," she said,
looking at me directly, "I hope you will be able to
manage, but if you have difficulty," she continued, now
looking at mom, "Perhaps your mom will be able to help.
It is nothing to be embarrassed about as we are dealing
with helping to resolve your condition for medical
reasons."

Dr Taylor paused for a moment, still looking intently at
mom.

"Would that arrangement be ok with you Mrs. Addington?"
I glanced a look at mom, who looked a little perturbed,
but then composing herself said, "Well it's going to be
a bit of a nuisance, and inconvenience to my routine,
but yes I'll do it Doctor, as it's for medical reasons,
and to help my son," replied mom. "As long as it gets
him sorted out."

She sounded a bit annoyed, but that was what she was
like when she had to do something out of the ordinary,
usually.

"Good," replied Dr Taylor, now looking at me and
smiling. "Don't be shy of your mom and ask her help if
you need it," she continued. "In fact, I would recommend
your mom helps you collecting your semen and doing the
measuring from the start as that way you will avoid any
mistakes and little accidents that may affect getting an
accurate result. I do need accurate measurements to be
able to make a proper diagnosis."

"Err, yea sure," I replied, a little stunned by the
implications of what she meant.

Dr Taylor stood up, indicating the consultation was
over. She handed mom the semen beaker and we shook hands
and said our goodbyes. On the way out I gave a blood
sample, whilst mom waited in the reception area.

There was a bit of a silence in the car for a while as
we began our drive home. I guess it was because of what
the Doctor had said. I didn't know quite what to think
and mom must have been having similar thoughts about it.
What she seemed to have said was mom would help me
masturbate into the beaker!

It seemed bizarre! Mom would see my erect cock and then
see me spurt my cum. God! That was a private thing to me
in my life so far, but now I was supposed to wank off in
front of mom! I felt a mixture of embarrassment and
excitement at the same time.

Mom eventually broke the silence. She spoke firmly and
without any embarrassment. "Well this all a bit of a
pain Jacob, but we must do what the doctor has
suggested. I will do my best to help you. We need to get
your problem sorted out and get back to normality. It is
going to be very inconvenient for me, but it has to be
done." She sounded ok about it but she also seemed a bit
pissed at me.

"Thanks, mom" I replied, a little awkwardly, and trying
to sound grateful.

"We'll talk more about this when we get home and how we
make arrangements for collecting, err, you know... your
semen. We'll have a chat after dinner. We probably won't
be able to start properly getting your samples until
tomorrow, so if you need to relieve yourself when you
get home you can do, but we might do one test run
tonight, so save yourself for a time with me when I will
be present when... you know... you masturbate."

I'd never heard mom talk like that before and my cock
stirred. I was semi hard when we got home and had to
cover the front of my pants with my jacket until I got
into my bedroom and wanked off. I came a bucket load.

I came again about an hour later thinking about mom
touching my dick. The ache in my balls had eased as
normal after cumming a couple of times, but I knew I
could still cum once more, which mom had suggested I
saved myself for.

We had dinner in front of the telly. Nothing more had
been said about how mom would help get samples of my cum
since we had got home.

After I finished my plate, mom said, "Finish the dishes
and then come back in here so we can have a talk."

I disappeared and did my chores.

Finally, when the last plate and spoon had been washed
up, I dried my hands and went back into the living room.
My heart was beating fast.

"Come and sit here." We had a three-seater sofa. Mom sat
on one end and she beckoned me to sit next to her on the
middle cushion.

"Now Jacob. This is going to be quite inconvenient for
me but we have to do what the doctor advised. Firstly,
as some people might not understand what we are doing
and that it is for medical reasons, whatever we do must
never be discussed outside this house except with Dr
Taylor. Do you understand that?" she said in a very
stern tone.

"Yes, mom" I replied meekly.

"Now, the other thing is that we need to discuss some
very personal things, and there is no point in getting
embarrassed with me about it. I have seen your body many
times before when you ********** and growing up,
although I haven't seen you naked for many years or in a
sexually aroused state. Whatever we do or discuss now,
you must remember it is for medical reasons, so don't be
shy with me."

"Ok, mom" I said. My dick stirred again.

"Firstly," she continued, "You'll have to tell me how
you masturbate normally, and what you do to arouse
yourself." She spoke in a schoolmistress sort of tone.

"Err... well," I paused, trying not to be embarrassed,
but not succeeding.

"Come on now, don't be shy," said mom encouragingly. "I
know most boys of your age have magazines of some sort
with pictures of naked women. Do you?"

"Well, yes, I do," I said, being up front about it.
"I've got some magazines and some videos and DVDs which
I read or watch, and then I normally masturbate onto a
towel on my bed. I keep a few towels only for that
purpose so as not to mix them up with the normal
laundry."

"I'm glad to hear that Jacob." replied mom in quite a
'matter of fact' way. "I'm glad you have the sense to be
clean."

"Well," she continued, "I certainly don't want to help
you when you're looking at such things. I don't want to
be in a room with you when you are looking at those
things, some of which are quite disgusting, I'm sure."

I blushed in embarrassment, and also felt a little
admonished about my porn collection.

"But," she continued, "I do have to help you masturbate
into the semen beaker. So I will have to see you naked,
and see your erect penis, hold it, feel it and stimulate
it, and make sure you cum into the beaker."

"You will also need some visual stimulation - we can't
really avoid that," she continued, again sounding very
schoolmistress like. "As you have told me some of your
personal 'secrets' so to speak, I will also tell you one
of mine.

"When your father was around, he liked me to dress up
for him in what you might call 'stimulating underwear'
before we had sex." She paused for a moment letting what
she had said sink in. "I did not mind doing that -- in
fact I used to enjoy it, as long as it was done
tastefully" she continued. "So what I am prepared to do
is stimulate you by dressing up in some suitable
underwear which will help you to cum more quickly."

My dick had turned rock hard as she spoke. I did not
quite believe what she was saying. So my mom had liked
dressing up in sexy lingerie for dad! Wow! And she was
prepared to do that in order to 'stimulate' me as she
put it! Fuck!

"Is that acceptable for you?" she continued.

Acceptable? Fuck, yea, I thought, but kept my composure
and acting a little, replied, softly, "Yea mom, if
you're ok with that?"

"Good," she said. "Now, a few other rules. Firstly, I
may let you touch me if I feel it may help you cum more
quickly. I don't want our sessions to last for ages as I
have my day-to-day routine to do, so it may help speed
things along if you are able to touch me. But, you may
only touch me by first asking my permission, or when I
say you can, and where you can."

I gulped.

"Secondly, and again, only because it may help to
stimulate you, we can use more normal day to day words
for our various body parts. I think it might be a bit
off putting if I used the word 'penis' all the time when
I was stimulating you, or if you said 'semen' instead of
cum. You may use normal slang word which men and women
use such as ass, bum, cock, pussy and tits, but, and
this is a big but, I do not want you to be very crude in
my presence unless I say you can. Do you understand?"

I couldn't believe I had heard my prim and proper mom
use such words. My cock was raging in my pants and
making me feel quite uncomfortable. All I could do was
nod in agreement and slight shock.

"Is there anything you want to ask me?" she continued.

My mind was still half in a daze, and all I could do was
say " I can't think of anything right now mom, but I
might later."

"That's fine," she replied.

"Now, the other thing is that it may be better to take
one sample in the morning and then the others in the
evening. How many times do you normally need to cum in
the evening?"

"Normally about 3 times," I said.

"That is a lot," she said. "Well, let's see what
happens. We'll both have to get up a bit earlier in the
morning during weekdays for the next two weeks if we are
to have one session in the morning."

"Ok," I agreed.

"Do you feel the need to cum now Jacob?" she said.

Fuck yea, I did, my prick was straining, "Yes that would
be helpful," I said, as coolly and politely as I could.

"Ok then. What I would suggest is you go to your room,
take off your clothes and lie face up on your bed. Oh,
and give yourself a wash down below -- I do insist on
cleanliness," she continued. "I'll go and change into
something suitable and come in with the semen measuring
beaker."

I got up. Mom must have noticed the tent in my pants.
She didn't say anything. I thought it didn't matter, she
would soon see my hard on in all its glory anyway.

I walked out of the room a little awkwardly, and almost
flew up the stairs, I went so fast.

I had my own bathroom attached to my bedroom so after
undressing, I gave my hard on and balls a quick wash. I
felt like I was going to cum quick.

I laid down on the bed on my back. I was now semi hard
as the washing had taken the edge off it.

As I lay there waiting for mom to come in thinking about
what she might be wearing, I started to get a full pole
again. I stroked it gently once.

After a couple of minutes, I heard a knock on the door.

"Jacob, are you ready?" I heard mom say in a raised
voice from the other side of the door.

"Yea, mom," I said. My cock was still rock hard and
sticking up like a pole.

The door swung open and mom came in. I took in the
wonderful sight. She was wearing a black bra and
matching panties and nothing else. She saw my hard cock
sticking up already and it jerked up again at seeing
her.

I saw her draw a heavy take of breath. "So you are hard
already I see. You didn't really need much stimulation
today." As she walked over to the bed I got a better
look at her body, although I tried not to stare too
much. She had quite large boobs, but the bra and panties
were a little old fashioned with quite a lot of material
and covered most of her private parts well. She came and
stood next to me as I lay on the bed. I saw she had the
semen beaker in one hand.

"You've grown a lot since I last saw you naked," she
said, looking at my raging prick, and then looking at me
straight in the eye. I thought I saw a slight glint in
her eyes I had never seen before.

"Now Jacob," she said, "I'm going to stroke your cock
and wank you off into the semen beaker. I'm going to
bend over slightly. You may touch my bottom lightly if
you wish, and it helps you to cum.

She stood level with my chest and at about a 45 degree
angle so that her ass was a bit more accessible to me,
and then she bent over me, her head towards my legs, and
started stroking her right hand up and down my dick.
With her other hand she put the beaker between my legs
near my groin, but not so it was touching me.

I saw her bra wrapped boobs hanging over my stomach as
she touched me and realised they were probably much
bigger than I had imagined.

"Go on," she said, "You can touch my butt lightly, but
you must tell me when you are about to cum."

I looked at her ass, which was largish, but not huge. It
was quite round and shapely and her black panties
gripped the flesh of her buttocks sexily. Some of the
white flesh was visible, under the thinner material of
the panties where they covered her buttocks, but there
was a thicker, non-see through material that covered the
line of her ass and pussy area. I don't think this
underwear was very modern, but it sure still turned me
on seeing mom almost naked next to me and sticking her
ass out at me.

As mom touched my dick I felt like I was in heaven. She
started stroking it up and down ever so gently at first.
With my left hand with was nearest her ass I started
stroking her butt cheeks gently in circular motions,
feeling the flesh there.

Her ass felt wonderful. I wanted to grope it hard and
squeeze the flesh there much more roughly, but I dared
not, and was quite soft and gentle so as not to put mom
off.

Even so, I knew I would not last long this first time.
Within about a minute of mom starting to pump my dick up
and down, and me feeling up her ass curves, I moaned,
"I'm gonna cum mom."

She grabbed the beaker quickly with her free hand and
then, still pumping my dick with her other hand, she
pointed the tip towards the open end of the beaker.

I closed my eyes, and with my left hand still playing
and feeling up moms wonderful fleshy ass cheeks in wide
round circles as she pumped my dick even harder now, I
shouted, "I'm cumming... oh... oh... ohhh!!" and I
spurted a ton of cum.

Mom had directed the tip of my prick right into the
centre of the beaker and gently milked my dick into it,
managing to collect all my spunk as I came. As my dick
became limp, she wiped the tip with her fingers, and
then wiped them into the beaker to collect as much as
she could from them.

"That's good Jacob, well done. We have a good test
sample," she said, pointing at the beaker and showing me
my cum had reached the measuring lines marked on the
side. I think our little arrangement will work well. You
get yourself cleaned up and I'll do the same," and with
that she turned and walked towards the door.

I saw her hourglass voluptuous figure fully from the
back now, with her white smooth skin naked and bare,
except for the bra strap and panties. I couldn't take my
eyes of her wide full ass cheeks as they wriggled and
wobbled in her knickers as she walked. Her ass looked
really sexy to me, and I wondered if I would ever see
more of it than in just old fashioned black panties.

I looked up at the ceiling after she had left the room
and wondered just how good the next two weeks would be.

To be continue?
