All Boys Private School

Part 9

Male Physiology 301
Sperm production
First Month of the Quarter

My name is Brent.  I'm your typical athletic 16 year old.  I'm 5'9" 155
brown hair, hazel eyes.  Lean muscled because I work out and like the look.
My third year in an all male private high school is great.  It's not that I
am huge; it's that I am fit, active and involved.  At 16 life is great.  I
lived with my Dad and enjoyed everyday.

Mr. Hardwood our Male Physiology teacher had a theory about sperm
production and it's relation to stimulation of the cock.

He wanted the class to use the quarter to gather data and come to some
conclusions.  We were to keep detailed measurements of sperm and document
our findings.  Using skills used last year again this year.  Mr. Hardwood
also wanted us to measure the flaccid penis and then the fully erect penis,
hopefully right before orgasm.

Dad was always happy to assist me in my education and this class was no
different.  That night I explained the class assignment, its duration, and
what we needed to do.

My Dad was a well built guy who took care to stay in the best shape he
could.  Lean muscled, defined, hard body, but not over done

The first month of the quarter I would bring my Dad to orgasm once every
three days; regardless of the day of the week.  The first load would be
taken Monday, 3 days later, Thursday, the second load would be taken; three
days later, Sunday, the next sample and so on.  The loads would fall on
different days of the week. Eventually taking in ever week day.  We had to
report what our family member had eaten in that time period, the size of
his cock at the session start and end, and the resulting load.

The second month I was to take a sperm sample once every fourth day
starting on Monday (I know this would be hard on Dad to not shoot his load
for 3 full days days).

The third month, however we where to get a sperm sample once a day for the
entire month if possible.  I know this would be a challenge.  But since
last quarter I had been learning stimulation techniques to bring any man to
a hard and fast orgasm, I was pretty confident Dad would come through.

Every Friday in class we would present our findings.  At the end of the
quarter the information would be crunched and final report made.  Each
student would be dealing with the male member of his family of his choice.

We were to collect the sperm sample at the end of the day, or in the
morning.

First Month's Sperm Loads from Dad

In the morning after breakfast I documented what Dad ate, and I knew what
he took for lunch as well.  Both protein packed meals with the right mix of
carbs and fiber.  Dinner was lighter fare, heavy on the veggies with some
multi grain bread.

That night when we were getting ready to get to bed I reminded Dad of the
sample I needed to collect.

"Dad, I need to collect that sperm sample for Mr. Hardwood's class.  Is now
a good time?"

"Sure Brent" Dad said from the bathroom, as he brushed his teeth.  "Ready
when you are."

I walked down the hall and stood in the bathroom door watching my Dad brush
his teeth with the bath towel warped around his waist.

His lean muscled body was a joy to look at.

"Don't go anywhere Dad" I intoned as I headed quickly to my room to collect
the things I would need to gather the sample.  Fabric Measuring tape, Lube
and sample container.

When I returned to the bathroom Dad was flossing.

First I need to take a measurement of his cock while soft, so speed was
important; I knew as soon as I touched his cock it would start to expand.

Removing his bath towel, I took his flaccid cock in my hand and with the
other holding the tape measure recorded the cock at 3.5 inches.  Even as I
took the measurement his cock pulsed and grew some.  I measured the
circumference at 3 inches.

I now moved up behind him and told him to continue with what he was doing.
I placed a small amount of lube on the tips of my fingers, positioned
myself behind Dad and reached around to his front and gently touched the
head of his cock with my lubed fingertips.

Dad's response was immediate; a small shudder ran though his muscled body
and his cock throbbed.  He paused for a second and closed his eyes.

When Dad composed himself I started my gentle stimulation of his glans with
my fingers.  Reaching around with my left hand and holding the base of
Dad's now fully firm cock, my right hand fingers swirled around his cock
head.  Each swirl of my finger tips would cause Dad's cock to throb and
pulse.

What was nice about this position is I could see Dad's face and body
respond.  As my hand gently moved down the shaft of his cock, he'd close
his eyes.  As my hand move up the shaft and swirled around the head, his
abs would flex and bulge.

As my fingers moved over the smooth head of his cock, my left hand could
feel his cock grow firmer.

I kept this up for a few minutes and noticed Dad had stopped his flossing
and was standing with his hands supporting himself on the sink, his eyes
closed and his legs spread apart.

Knowing that Dad had been eating a high protein diet for the last several
days, that it had been three days since his last orgasm, I felt this load
would be sizeable.  Probably fill half the sample bottle.

My fingers kept moving over Dad's cock head and I knew he would not be able
to hold out for very long.  We both needed to get to bed, but prolonging
the stimulation would also result in a large load being shot.  I learned
that from the last class.  The longer the stimulation, the greater the load
delivered with the orgasm.

To speed things along I began to work first the top of Dad's glans and then
the frenulum area.  Swirling one finger then two around the ridge of his
cock head.  Round and round my fingers went.  First one direction then the
other.

With each swirling round of my fingers, Dad would clench his butt and I
could feel his cock swell in my left hand.  Precum soon flowed from his
cock and I knew how to make use of it.  A soft moan of pleasure issued from
him.

I noticed his breathing was speeding up and I could feel his cock pulsing
stronger and more frequently with each touch.

With plenty of my Dad's precum now available, I gently spread the clear
liquid all along the shaft of Dad's firm pulsing shaft and then took it
firmly in my right hand.

I began to slowly move my hand up the cock shaft until I reach the glans
where I swirled my palm over the cock head.

"Oh Brent that's good son.  It's been a few days since I had an orgasm."

As my hand moved up and down Dad's slick cock, his balls began to pull up
and the sack tighten.  I knew that soon he would not be able to hold back
his orgasm.  I let go of his cock with my left hand and readied the sample
jar to catch every last drop of his sperm.

I began to stroke his cock faster applying gentle pressure to the head on
the upward stroke.  Each downward move was slow and steady.

"Brent, I'm gunna cum if you keep this up."

At this point I had to stop and measure Dad's throbbing cock.  As quick as
I could, because I knew he could shoot now, I measured his cock; 7.5 inches
head to base, and 6.5 inches circumference.  Amazing tool.

Dropping the tape measure and committing the figures to memory, I grasped
Dad's cock once more and gave it three quick strocks.

"Ahh Brent, yeah keep that up, I'm gunna blow my load."

That was my cue that ejaculation was immanent.

With my chest firmly against Dad's muscled back, my left hand holding the
sample jar to collect his sperm, my right hand stroking his thick cock, my
Dad began to shoot white ropes of sperm into the sample jar.  Six blasts in
all flew into the jar.

Dad's entire body went stiff as he shot his loads into the jar.

When his orgasm was over he relaxed, "Wow Brent that was amazing.  It's
been a few days since I last shot a load.  Thank you I needed that before
bed."

"Sure Dad.  I'm glad you're so willing to help me with my class work.  And
look at this, you filled the jar to the half mark.  That's a large amount
of sperm.  I wonder if the high protein diet accounts for that."

"Don't know about that Brent, but what I'll do is eat more fruits and
vegetable for the next three days and we'll see what happens."

"Great.  That will be a good comparison."

Dad cleaned up and made his way down to his bedroom.

"Good night Dad, see you in the morning."

"Good Night son."

Over the course of the first month, I collected the sperm samples as
directed.  Each orgasm my Dad had was better than the one before, at least
in terms of his enjoyment.

The best sample I got was when I used my tongue on Dad's glans while at the
same time stimulating his prostate with my finger.  His arched his back and
I was just seconds ahead of his sperm flying down my throat.  Fortunately I
was able to collect the sample.  Maybe next time I'll not be so lucky and
the spunk won't make it into the sample jar.
