Science Affair



Chapter 4

I woke with somebody knocking on the door and Kathy was saying, "Yes
mother! I'm awake! I sat bolt upright. I looked at Kathy and tried to
gather my wits. "Get into your room!" She whispered as if she was
telling an idiot. I suddenly realized what was happening. I hopped out
of bed and ran through the bathroom into my room. Mom was knocking on my
door and she was peeved.

"Mike! Answer me this minute!"

"Sorry Mom, I'm awake." I was trying to sound sleepy, not out of breath.

"I swear! The older you get the harder you are to get up!" She stomped
off down the hall and I sat on my bed to calm down..  Kathy stuck her
head through the door and asked me to wash her back. She had started the
shower and we got in together. She wet her hair and I rubbed her shampoo
in. It was neat washing her hair. It seemed such a personal thing to do.
She was humming as I did it and once in a while her slick soapy ass
would brush against my cock. It started getting hard and Kathy felt it.
She pushed her ass against it and wiggled against it. It rose up between
her legs and she wiggled her thighs. I was still soaping her hair, but
it was getting harder to concentrate. I pushed my cock forward against
her pussy and she spread her legs a little. My cock slipped between her
pussy lips and I started stroking in and out. Kathy spread her legs
further apart and placed her hands against the shower wall. My cock must
have been stroking her clitoris directly because she got real slick
fast. After a couple of minutes I pulled back a little further and it
found her hole. I grasped her hips and pushed it in further. She bent
over further and kept her hands against the wall. I started stroking
faster. I reached under her, cupping her slick tits in my hands, then I
started pinching and pulling her nipples. She responded with a groan and
pushed back against me as I pushed in. We were going pretty well now. I
brought my left hand down her belly and through her bush to the top of
her slit. Her clitoris protruded and I rubbed it lightly with the tip of
my finger. She pushed back harder when I thrust into her. I set up a
rhythm of brushing her clit when I pushed in. Several more strokes and
she was starting to shake her ass against me when I was the in. The
shaking caused my  finger on her clit to  rub it harder. She was telling
me to push harder. I was more than ready and I really started pounding.
My cum was rolling in my balls and Kathy was shaking hard now. I gave
two more thrusts and I started blasting into her. Over and over I pumped
cum in her and it finally stopped. Kathy raised up and my cock popped
out of her. She turned to me and threw her arms around me and kissed me.
Her warm slippery tits rubbed against me and I started having thoughts
of round two. Then I realized we had school today and Mom was getting
dressed down the hall.

"We had better hurry."  I said into her wet soapy hair.

"Darn!" She must have felt the same as I about round two. She stepped
back under the spray and I rinsed the soap out of her hair. I soaped her
tits, back, ass, pussy and legs. Then I got to run my hands all over her
slick soapy body as I rinsed her off. I got a few kisses and licks to
her tits in the process. She laughed when she slapped a slick breast
against my lips. It was fun but it had to stop.  She stepped out to dry
and I finished quickly. I stepped out to dry as Kathy sauntered by
giving my now limp cock a little pat. I shaved and brushed and went into
my room to dress. Kathy had closed the door to her room. I gathered my
books and papers and went down to breakfast. Mom was dressed for work in
a smart suit and conservative blouse. She would show no jiggling tits
for the office today. Her eyes were sparkling and she gave me a cheery
kiss and hug. She looked like a new woman. The wonders of good fucking!
Kathy came down as I was eating my cereal and toast. She was sparkling
eyed too. Mom gave her a cheery kiss and hug too. "Boy Mom! You look
great today!" Cathy smiled at her.

"Oh I feel great!" Mom was as enthusiastic as I remember her ever being.

In a reserved voice Kathy warned. "Better cool it a little today Mom.
Somebody might wonder what's up."

Mom looked at us inquisitively. "Does it show that much?"

Kathy and I looked at each other and we both chorused a loud, "Yes
Mother!" We all laughed and settled back into the routine of breakfast
and cleaning up. Mom reminded us to come right home after school. We
chorused. "Yes mother!" She kissed us and we headed out the door. On the
way to Chuck's I suggested we act normal with him and if the subject of
Mom or sex came up we would be honest with him. Kathy thought we might
suggest to Chuck that he and Kathy date each other once and a while.
That was a really good idea. I thought we could double date or
something.

Kathy warned me, "Don't stick my cock in some whore."

"I love you alone babe." I meant it! I kissed my fingers and touched her
lips.
We pulled in front of Chuck's and he came running to the car. Kathy slid
over to the middle and he got in.

"Morning stud!" Kathy's greeting caused him to smile and she hugged him.
As we drove to school Kathy told him that maybe they ought to date once
in a while to divert attention.
Chuck smiled and thought it was a cool idea. We parked and walking into
school, Kathy held his hand. Several heads turned at that sight. Chuck
and I parted with Kathy and we went to Miss Monroe's room. She still
looked hot to me and I was wondering if she came like Kathy did. We gave
her the drawings and a brief explanation. She was excited about it and
gave us both an excited tits in the chest hug again. This time I hugged
her back.

"Let's discuss it further during Study Hall." She was smiling and I
could see the gears turning behind her eyes. We gave the servers a quick
look and made it to class on time. Study Hall was the next to last
class. Chuck and I got our passes from Mrs. Aronson and went to Miss
Monroe's room. Miss Monroe came around to the front of her desk as Chuck
and I sat in front of her. She leaned her butt against the desk and put
her arms down for support. Her breasts were thrust against her blouse
and the nipples were clearly outlined. She talked as if we weren't
staring at her tits, but her nipples were getting hard. She knew and I
knew. She had a twinkle in her eyes and I'm sure I did. She told us to
determine the accuracy of our measurements by calculating the deviations
in measurements of the same subject. We needed to know the repeatability
of the measurements. She suggested we measure the subject three times
and if there were significant deviations we had to refine the accuracy.
She also suggested we measure as many unrelated subjects as those that
were related. I asked if we should include different body types and she
pondered that for a minute. During the pause I looked closely at her
tits and I saw her stomach ripple. Was Miss Monroe getting turned on? "I
don't think seriously overweight subjects should be used. The extra body
weight could distort the measurements." She wiggled her leg in and out
as if she was squeezing her thighs together.

I had been thinking about a way to sort the measurements to determine
mathematically those that were genetically similar. I brought up the
idea and Miss Monroe clasped her arms under her breast and squeezed them
together a bit. Her nipples were definitely hard! I picked up one of the
drawings and stood to show it to her. I was getting a hardon and she may
have noticed it. I stood to her side and pointed at the lines connecting
the coordinates.
"If we summed the lines or summed the angles we might get a significant
deviation between unrelated subjects. " I was leaning toward her. She
placed her hand on my arm. It was very warm and she squeezed it. She
smelled like my wet dreams.

"That's a wonderful idea Mike!"  Her hands were back on the desk now and
she seemed to be pushing her tits toward me. "You might be able to
determine probabilities of random subjects being related." She was
excited by the idea and her thighs were definitely squeezing
rhythmically.

I gathered my courage and asked the question I was dying to ask. "Miss
Monroe, would you be one of our subjects?"

Her forearms came back to squeeze her tits and she smiled at me. "Sure,
I'd be honored."

"Should we take your measurements here?" I was hoping she would say no.

"Why don't we do it at my home? It's convenient to school and we won't
be disturbing your parents." She leaned forward a bit and crossed her
ankles. The free foot was wagging back and forth like a metronome. It
must have been keeping time with her pussy squeezes. She gave her
address to us and we settled on tomorrow after school. We would meet her
there.
Chuck stood and Miss Monroe kept her hands on the desk. My dick was
tenting my pants pretty good now. I didn't try to hide it. If she was
proud of her tits, I was proud of my dick. We walked out and she was
still leaning back, watching with parted lips, when I looked back. God!
She was hot! Out in the hall Chuck was laughing about her tits. I don't
think he had understood the hidden agenda.

After school we dropped Chuck off at his house. I explained that Mom had
given us some errands to run before she got home. We went in the house
and the answering machine was blinking. It was Mom. She told us Kathy
had an appointment with a gynecologist at 4:00. It was with a Dr. Metz
and she was in the same building as our family doctor. On the drive over
Kathy was excited to be seeing a gynecologist. It was as if it validated
her sexuality. We arrived on time and after Kathy filled out the
necessary form we waited for a few minutes and the nurse called her
back. It was at least half an hour before she came out. She gave me her
perturbed look as she talked with the receptionist and out the door we
went. She was laughing with relief as she explained what had happened.
The doctor gave her a thorough pelvic exam, breast exam, blood pressure,
blood test (she showed me the bandage), weight, height and poked and
prodded her every where. But the worst part was the questioning. How
many sex partners had she been with? How long had she been having sex?
Had she had unprotected sex? Were her sex partners active with others?
Did she know her partner's sex history? Was she aware of the dangers of
unprotected sex? On and on it went. Then the doctor loaded her down with
brochures and explained how to take her birth control  pills. Since she
was already a week and a half into the cycle she should not depend on
the pills to effective until the next cycle.

I was appalled! "Does that mean we can't have sex until after your next
period?"

She laughed. "No silly, it means you have to use condoms! We have to
pick up my pills at the drug store. You can get enough condoms to last
us for three weeks."
We parked at he store and went in. While Kathy was getting her pills I
surveyed the condoms. I had not realized there were so many different
kinds. I picked out a box each of three different kinds and took them to
the checkout. The girl was my age and she flirted a little as she rang
them up. I paid and went to the car to wait for Kathy. She came bouncing
out of the store a few minutes later and hopped in.

"Did you get them?" She asked as she took the bag and looked in. "Oh
neat! Let's try one out when we get home!"

"We don't have much time before Mom gets home." I was sure we would need
more than a half-hour.

She pouted a bit then said, "OK, but I'll be really horny by tonight!"
Fair warning. I got hard thinking about tonight. We drove home and Kathy
chatted on about her doctor experience. She went into her room and I to
mine. A few seconds later, wearing sexy underwear, she came into the
bathroom. Without closing the door to my room, she sat down to pee. I
stuck my head through the door and watched her. She looked at me and as
she was finishing she gave me that evil smile. "Wanna wipe me?"

My cock sprang up quickly. "Sure!" I was in front of her in a second and
on my knees. Her panties were at he knees, so I pulled them to the floor
and off her feet. She spread her knees wider and there was that
beautiful pussy with a few drops of piss glistening on the lips. I
reached for the toilet paper and wound a few wraps on my hand.
Delicately I dabbed at the drops.

"Do it harder." She was smiling at me when she gave the order. I reached
to her cunt lips,  spread them apart with my free hand and gently wiped
from her cunt to her clitoris. "Did you get it all?"

"Here, let me find out." I pulled her toward me so her ass was on the
front edge of the seat and lowered my lips to her pussy. Holding the
lips apart with my fingers I lightly licked from her cunt hole to clit.
There was a faint smell of piss over-ridden by the wonderful smell of
juicy cunt. This required further exploration. I had never inspected her
pussy this closely before so I leisurely looked, licked, kissed and
sucked every point of interest from her asshole to her belly button.
Kathy was murmuring affirmatives when I touched a particularly sensitive
spot. Her clit was the definite favorite. My favorite was her cunt and
the delicate inner lips. A lot of her lubricant seeped from her cunt and
my lips smeared it around well. At one point I pursed my lips and rubbed
them from her cunt to her clitoris and back down. She held my head
lightly when I did that and quivered. Better do that some more. I began
a slow rhythm with my lips, up and down, slowly smearing her juice from
cunt hole to clitoris and back. Oh, she liked that a lot! I continued
for several minutes. Her finger were grasping my hair lightly after a
couple of trips. By ten trips she was pulling my face to her pussy a
little harder. After about twenty I stuck the tip of my tongue out
between my still pursed lips. She clutched me even harder. Know she was
getting close and I started watching her tummy on my upstroke. Sure
enough, the little ripples were starting. Her pussy lips were wide open
for me now. No need to hold them open. I slowly pushed two fingers into
her cunt with my palm up. I was feeling the inside of her cunt as I
entered. At the beginning it felt slippery smooth and the heat was
amazing. As I got a few inches in, there were a couple of soft ridges
that ran across my finger. About and inch after the ridges I felt soft
tissues that felt similar to the skin of an orange. I moved my fingers
around to measure the area and Kathy groaned loudly. "Oh yes! Again!" I
stroked the area again and she ground her pussy against my face hard.
Over and over I rubbed that strange feeling area and Kathy was grinding
hard against me. I sucked her clit hard and rubbed that strange tissue
harder and she blew up! My face was crammed to her pussy and she was
fucking her cunt against my fingers hard and fast. Deep guttural groans
and swearing were coming out of her as she was bounced on the toilet
seat. If she hadn't been pulling my head to her pussy so hard, I'd have
lost contact. Her orgasm lasted a long time. When she finally settled
down and released my head, I thought my lips must be bruised. She was
panting hard and sweat on her tummy was glistening. I looked up and her
tits above the bra cups were wet too.

"God Mike! What did you do to me? That was the hardest orgasm I've ever
had! You can wipe my pussy anytime!" She pulled my head to her breasts
and hugged me hard. My knees were killing me, so I reluctantly pushed
away from her, and groaning I stood. My cock was tenting my pants. Kathy
leaned forward and kissed it through the fabric. Then pulling me against
her face she blew hard against my cock. The instant heat almost made me
cum. I must have gasped because she did it again. Damn! That felt
wonderful! She pulled back and started undoing my belt. In a few seconds
she had my pants and skivvies to my knees,then grasping my cock, plunged
it into her mouth. I almost came again. Her tongue circled it a few
times and she pulled back a little. Still grasping the base, she plunged
it back in as far as it would go. I started fucking into her mouth as
the cum built. Her tongue was pressing on the underside and her lips
were pursed tightly around it. A half dozen strokes and I came hard. She
was noisily slurping and sucking as my mind blanked and my knees turned
to warm Jell-O. When I came back to earth she still had it grasped
firmly and was kissing the tip with little smacks and licks. She was
murmuring something I couldn't hear. Little shivers were running from my
knees to my neck. The hair on my neck was standing.
"We may never need those condoms!" She said it emotion and I certainly
agreed. As I stepped back Kathy's phone rang. She jumped up to get it
and ran bare-ass into her room. It was Mom. "She's bringing Chinese for
dinner." It was fine by me. I was suddenly starving. We washed up and
Kathy dressed in T-shirt and shorts, no bra. She remembered the mess we
made in her bed last night and stripped it. I started the laundry while
she remade her bed.

We were studying in our rooms when Mom got home. Kathy and I went to the
set the table while Mom changed. She came down dressed just like Kathy,
no bra. I loved the way her tits jiggled and rolled. As we ate Kathy
described her doctor visit in great detail and with a lot of laughter.
I talked about the project and what Miss Monroe suggested. Mom was very
interested in the project and made a few suggestions on changing the
frame to make the readings more accurate. She knew what she was talking
about. She had been an engineering student when she married Dad and she
ran the construction company by herself.

After we finished and cleaned up I called Chuck and he came right over.
By cutting through the park he was only two blocks away. By car it was
two miles. When he came in he looked only at Mom. She smiled brightly at
him and walked quickly to him, tits jiggling and swaying. "Hi honey!"
She clasped his face in her hands and pulled him down for a short kiss
on the lips. They were both flushed when she stepped back.

I called Chuck to the garage and we started making some of the
modifications Mom suggested. We built slides from metal strapping and
two more guides. We attached the guides to the posts with the slides. We
made another slide to slip over the guides and we had to work for a
while to make it slide smoothly, while keeping the ruler at right angles
to the sides and horizontal. When we finished I went in to get Mom and
Kathy. They came jiggling out together. It was a wonderful sight. Kathy
sat first and we started her measurements. The coordinates were a little
different than the first time. It was probably due to the chair position
in the frame. Next we did Mom and when Chuck bent close to her face her
nipples got hard and he popped a woody. I had to remind them to stay
focused and we finished the readings. They were nervous and Mom giggled
a little. We had Kathy sit and we did her again. The readings were a
little different again. We did each of them three times and by the time
we were done with Mom, she and Chuck were staring at each other
constantly.

"Mom, why don't you and Chuck go talk? I'll help Mike." Kathy's
suggestion brought a startled look from Mom. She looked from Kathy to me
and I nodded. She looked at Chuck and he nodded.

"Well I guess, if you don't need any help." Mom's eyes were very bright
and her cheeks were flushed. She stood and gave Chuck a questioning
look. He licked his lips as Mom turned and headed for the door. Her hips
were swaying a lot more than normal and Chuck's pants were tented big
time, as he followed her out. Kathy smirked at me and she scampered to
the door to spy on them. I couldn't resist either. They were going up
the stairs side-by-side and their hands were on each other's ass.

Kathy chortled, "Mom is so hot!"

I added that Kathy came by it genetically. She gave me a quick hug. We
put everything away and went up to my room. We entered the coordinates
and I plotted each picture. The deviation from the first plot was up to
a quarter inch from the second, but the last three were within a
sixteenth when I referenced all points from the tip-of-the-nose
measurement. Kathy had gone to her room to study while I finished
adjusting the coordinates, then I went to work on my homework. It was
almost 10:00 when I heard Mom and Chuck leave her room. Mom had on a
nightgown and they were going down the stairs. I called to them and they
came back up to my room. Mom had that rosy satisfied look and Chuck just
looked dopey. He couldn't keep his eyes off her.  I showed them the
plots and when I put the three of Kathy together and put them up to the
light they we an almost perfect match. I did the same with Mom's and
they matched. Then I took one of Mom's and laid it over one of Kathy's
and held it up to the light. They were almost exact. Kathy's eyes were
about an eighth of an inch further apart than Mom's. The angle of the
eyes to the nose was exactly the same. It was interesting that Kathy's
left ear was a little lower than her right and so was Mom's. They oooh'd
and ahh'd over them for several minutes. Mom had sat on the edge of my
bed when she held the plots to the light and crossed her legs. Her
nightgown split open almost to her pussy. Chuck and I were both staring.
She didn't seem to mind. She had great legs and framed by the blue satin
they were hot! We talked about doing the other subjects and I told Kathy
I had to stay after school to do Miss Monroe. She would get a ride home
with Gina and that was settled. Chuck had to get home so Mom walked him
to the door.  Kathy smirked as they left my room, then made a fanning
motion to her crotch and mouthed the word "hot". I chortled and pointed
to my hard-on.

"Mom give Mikey a boner?" She asked innocently.

"Kathy's pussy get wet?" I promptly retorted. Her eyes opened wide and
she placed her hand over her mouth and nodded a big affirmative. She
started laughing loudly and dropped her arms and head to my shoulders,
laughing so hard she was crying. I couldn't resist and I was laughing
too.  We were like that when Mom came in.

"What's so funny?" She asked with a smile. Kathy raised her head from my
shoulder to look at her and started into a fresh outburst. I joined in
and tears were rolling down our cheeks while Mom waited patiently for us
to return to sanity.

Kathy finally calmed. Raising up, she turned to Mom and said with a warm
tone in her voice, "Mom, you and Chuck were so sexy when you were in
here we got turned on too! It was too funny!"

Mom's eyes got wide and her mouth dropped open. "You guys are too much!"
She was shaking her head, but smiling. She turned with a flip of her
chin and a flair of her nightgown and strode out the door like a movie
star. Kathy gave me a wide-eyed smile and went back to her room to
study. It was after 11:00 when I finished studying. I went to the
bathroom to piss and brush and looked in on Kathy. She was asleep on her
bed. She had her T-shirt and panties on, her books beside her. I stepped
in. put her books on the desk and covered her. She licked her lips and I
had to stop myself from kissing her. I turned the lights off and closed
the door as I went into the bathroom.
