 Jim Helms had taught Social Studies, Civics, and History for fifteen years.
Since he had started his teaching career, right out of college, he had
accomplished a great deal and had seen a great many things.  He had gotten
married, gotten his Master's degree, gotten divorced, served as advisor to
several clubs and groups, chaperoned school functions, and had an affair
(that did not cause his divorce) with a seventeen-year old girl who thought
like she was thirty-five.  He thanked his lucky star that the Board of
Education never found out.

   The teens always surprised him.  They were witty, charming, bright,
intelligent, and inquisitive.  The inquisitiveness, however, sometimes
drifted to the negative.  He had caught both boys and girls drinking and
drugging in the parking lot, having sex, fondling each other on the dance
floor, and playing with each other on school trips.  In short, they were
crazy, normal adolescents.

   When he first started teaching, the girls used to rattle him.  Wearing
too-short minis, and sitting in the front of his class, they would let the
skirt ride up so he could catch a glimpse of their panties.  Sometimes the
girls would not be wearing panties.  They enjoyed his startled reaction
when he got a peek.  After a year or two, Jim learned how to look and not
get caught.  It amused him when the girl got a bit frustrated because he
did not seem to catch her show.  In reality, he took advantage of any peek
that they let him have.

   The past two years, Jim had lived a fairly quiet and sedate life.  He
had dated a few times, and partied with friends.  There was the occasional
visit to a strip club, which he enjoyed, and some Internet porn.  Other
than that, he rode his bicycle, did some counseling at a summer camp, and
developed into an excellent teacher.  When the next school year started, he
was totally unprepared for the double shock he would get.

   Both shocks hit him full force on the same day.  It was the first Friday
of the school year, and the first football game.  The school had a pep
rally in the gym to close out the school day.  The cheerleaders wore their
uniforms to school all day long, in order to boost school spirit.  What
hammered him, and woke up his libido in a huge way, was a student in his
class who happened to be named Sabrina and was a cheerleader.

   The first shock was the new cheerleading uniforms themselves.  They were
really more than a bikini with a very tiny skirt.  The top was a crimson
jog bra (the school colors were crimson and white) that was very tight. 
The front was white with the school nickname across the chest and the back
was crimson.  With some of the larger-breasted girls, you could see the
outline of the nipples.

   The skirts were flared, so they would flow out as the girls cheered. 
They were crimson with white panels, and barely covered the girls red
panties.  The panties did not look like the usual tights a cheerleader
would wear but looked like a regular panty, although of a somewhat heavier
material.  How the school board, let alone the parents approved this
uniform, escaped Jim.  But the girls seemed to like wearing them, and the
boys loved them.  No one complained.

   The second shock was Sabrina herself.  She was a petite, five-feet
one-inch blonde with big blue eyes, fair skin, and an engaging smile.  She
had thin legs and a thin waist, which the uniform showed.  She also had a
nice rounded bottom and c-cup breasts, which made her look top-heavy.  With
those breasts poured into the cheerleading uniform, she showed a bit of
cleavage.  She was in Jim's second period World Cultures class, and sat in
the front row in the seat Jim had assigned her.  And the minute he saw her
take her seat, and caught a glimpse of the panties as she swiveled forward
on her desk, he knew he was in trouble.

   Jim settled in and began to teach.  Every time the girl moved a bit, her
top jiggled and he got a glimpse of her panty.  The worst part of the
situation was that Sabrina did not appear to be flashing.  She was a good
student and acting like a good student should.

   Jim went to the pep rally at the close of classes.  The cheerleaders and
the band had the student body hopping, and the football team sat at one end
of the gym, dressed in shirt and tie, and tried to look humble.  There were
more than a few who had their eyes glued to the girls.

   There were twenty cheerleaders in all, ten girls and ten guys.  The guys
really didn't do much except help the girls with their lifts and jumps. 
The girls did most of the cheering, dancing, and gymnastic routines.  Jim
smiled at the scene.  He was a bit envious of the guys.  They got to touch.

   There were two large-breasted girls in the cheer squad; Sabrina and a
girl Jim did not know named Kate.  Several times, after several high lifts
or jumps, it appeared as though they were going to pop out of their tops.
Kate blushed every time that happened.  Sabrina, on the other hand, merely
grinned.  And she had come close on more than one occasion.

   The other sight to see was the action of the short skirts, flaring out
around the girl's waists every time they spun in a circle and flying all
the way up whenever a guy helped them with a lift and jump.  Everyone in
the gym knew the shape of the girls' legs and bottoms by the end of the pep
rally.  Jim watched Sabrina and noticed her panties rode up on several
occasions.  She would pull them down the first chance she had.  He was
correct in his guess.  These were panties, and not cheerleader tights.

   As Jim watched, he developed a raging erection.  He hadn't had sex in a
while.  And Sabrina was getting him overheated.  He had had an affair with
a student once before and gotten away with it; why not try again?  He was
pretty sure, however, that Sabrina was innocent.  He would have to approach
this one carefully.

   What Jim Helms didn't know was that Sabrina was anything but innocent.
She was a very sexually aware and knowledgeable girl.  She was sexually
active, but very careful of her partners, preferring older guys or men with
no objection to race.  She found black men very attractive.  And she had
also dabbled a bit in girl-girl sex.  She was very, very good at hiding her
sexuality and displaying innocence.

   Sabrina had started exploring her sexual side at age fourteen, during
the springtime of her freshman year.  It was very much kid stuff, but it
was a beginning.  She had let two fifteen-year old boys play with her
breasts.  The fondling took place in a secluded area of the town park or at
one of the guys' homes when his parents were out.  It was really pretty
harmless.  First it was over-the blouse, then over-the bra, and finally
under-the-bra.  Sabrina loved the sensations of having her nipples teased.

   By summertime, and the close of school, it had gotten a bit more
adventurous.  The boys were playing inside of Sabrina's panties.  Sabrina
loved the sensations, and the guys really watched seeing her squirm and
wiggle.  They didn't know it, but on several occasions they had gotten her
very close to her first orgasm.

   Roughly half way through the summer, the three got a bit more daring. 
Sabrina had let the two boys see her completely nude.  She liked it.  And,
quite by accident, she had her first climax.  She was nude at the one guy's
house.  His parents were away.  She was lying on the floor, a pillow under
her head, with her legs spread and knees bent.  One fellow was gently
tweaking her nipples, the other playing and exploring with his fingers
between her legs.  He accidently found her clitoris, and when she gasped
and squirmed, he continued to play.  When she gently cried out and wiggled,
her thighs quivering, the boys were both shocked and delighted.  They let
her come down from it and repeated it.  Sabrina responded by giving them
both hand jobs.

   This sort of play went on until October of Sabrina's sophomore year.  It
was then she decided that she wanted their cocks inside of her.  Her
orgasms were very intense, and she felt that a cock would be better than
fingers.  Her mother, assuming that the girl was sexually active, had
gotten Sabrina on the pill.  Sabrina had no fear of pregnancy.

   Sabrina's first penetration was, in effect, a gangbang.  Her hymen had
ruptured at age thirteen because of the gymnastics and cheering she had
been doing.  There was no pain, just an unusual sensation.  The boys,
however, had gotten better at controlling themselves and the hand jobs
began to take longer.  Sabrina decided she wanted them inside of her.  She
gently stroked the first boy, and guided his penis into her.  She did not
climax.  She did, however, adore the sensation of a penis in her vagina and
the brief tickle of the ejaculation.

   Sabrina would continue to have sex with the two boys throughout her
sophomore year.  Right before the end of the school year, the relationship
would end.  Over the summer, Sabrina would have sex with her first black
man and learn the joys of an oversized penis.  And during the fall of her
junior year, her first year on the cheer squad, she would experiment with
girl-girl.
   This was the "innocent" that Jim Helms had awaiting him.
