The Fitness Instructor, Part 1
By Madcat
A man makes a bet with the wrong woman.


Missy tepidly walked into Adam’s office. He owned the small health club where
Missy worked as a Fitness Instructor. She still could not believe what she
intended to do. Adam’s wife had a few hours previously told her of a
conversation that the couple had over the weekend. The more Missy thought
about it, the more it pissed her off. She finally decided to talk to him about
it.

"Hi, boss." Missy said in her usual cheery voice.

"What’s up?" Adam replied in an irritated tone. His numbers for yesterday
refused to add up despite his best efforts. After looking at Missy in her skin
tight, black exercise outfit he knew he would have to start over. He could not
understand his strange attraction for this athletic woman. She looked like a
white version of the tennis star, Serena Williams, heavily muscled but well
rounded in all the feminine places.

" I heard what you said about me this weekend. I just wondered if you wanted
to put your money where your mouth is."

"What on earth are you talking about?"

"You told your wife that no girl could ever take a man in a fight. I think
your wrong."

Adam remembered the conversation now. His wife was singing Missy’s praises as
she was prone to do. She told Adam that Missy was bigger, stronger and faster
than he was. His wife also told him to be careful around Missy because she
could probably kick his ass. Adam vocally dismissed her entire claim
especially the last part.

"Are you challenging me to a fight?" he asked.

"I thought a wrestling match would be better."

"Impossible."

"You’re not afraid of me are you?" Missy teased.

"No, I’d hate to see you get hurt." He replied. "You’re just a girl."

"How about this: we arm wrestle first. If you win its game over and I go tell
your pretty little wife what a macho stud you are. If I win, then we head
downstairs and wrestle."

Adam thought for a second. He never thought he could lose even though Missy
was an inch taller and probably 10-20 lbs heavier. Adam had played baseball in
college and worked out religiously. While not a bodybuilder, he considered
himself to be in excellent shape. Boy, it’d be great to go home and brag to
the old lady that he had defeated her pet amazon.

"Sure, OK." He said.

They cleared and spot on his desk and locked hands. Missy had a strong grip
and her bicep grew enormously as she prepared for battle. Adam barely noticed
since he was busy looking down at Missy’s low cut top. He wondered if her
enormous breasts were real or improved.

"Ready, go." Missy said. Both man and woman started cautiously. Neither wanted
to over commit. As Adam ratcheted up the pressure he finally noticed Missy’s
massive bicep. The first doubts crept into his mind as the fitness instructor
showed no signs of weakening..

Missy noticed that Adam appeared to be really straining. She decided to go to
full power to see if she could overcome him. Immediately her hand began to
force his to the desk. A big smile crossed her lips.

Adam about lost his bottom jaw when his hand started to descend. He redoubled
his efforts and managed to get back to neutral. He looked and Missy, saw the
smile, and knew she was toying with him. His hand began to fall again. This
time it stopped only an inch from the desk.

"Did you forget to eat your Wheaties this morning?" She teased. Just to add to
the humiliation Missy fixed her hair and read something on Adam’s desk all the
while holding his arm in place.

"Just, end it." Adam admitted defeat.

"Yes, sir." Missy added sarcastically as she dropped Adam’s hand the rest of
the way. "You ready for that wrestling match now?"

"I still don’t think it’s a good idea. Lets just drop it. I’ve got work to
do."

"OK. I’ll just go tell the rest of the girls about our arm wrestling match.
And I’ll tell them you are scared to go toe to toe with me."

"Man you are tough bargainer. I’ll be along in a minute."

"See you in the studio. I’ll get the mats out."

Adam sat in his chair trying to finish his number crunching but his mind
remained focused on his arm wrestling loss. It was painfully clear the match
wasn’t even close. How could he lose to a girl? How did Missy get that strong?
Wrestling with her did not seem like a good idea but he had no choice. He
headed down to the studio with building anxiety.

Missy passed the time waiting for Adam by stretching. As an ex-gymnast she had
amazing flexibility. Her easy victory over Adam had built her confidence. She
was ready to complete her conquest. Missy began to visualize herself
dominating her boss. He lay at her feet trembling and naked. She stood over
him, tall, proud and strong. Much to her surprise, she felt the unmistakable
tingling of sexual desire.

The door opened and Adam jogged in doing his best to show off some macho
swagger. Missy chuckled at Adam’s minor league bravado and went over and
locked the door. She did not want any interruptions. When she turned around,
Adam had removed his tee shirt revealing his well defined chest.

"Why do you take off your shirt?" She asked.

"First rule of wrestling: don’t give your opponent anything to grab."

"Oh, really. Good idea." She responded. Missy followed suite by peeling off
her own top leaving her in just a pair of black spandex shorts.

For the second time today Adam’s jaw fell open. He stared at Missy’s large,
gravity defying breasts. Her large brown nipples looked like giant eyes
staring back at him.

"What’s the matter? Never seen a girl before?" Missy joked as she ran her
hands up and cupped her breasts. "They do look nice don’t they?"

Adam nodded.

"Maybe you’ll get a better look at them in a minute or two." She said as she
started to advance towards him.

Adam circled looking to avoid taking her head on. He had trouble tearing his
gaze away from her awesome chest. Twice he had to spin away to avoid her
grasp. Then he saw his opening. Missy was standing too tall and failed to keep
him to her front. Adam grabbed her right leg and dumped her unceremoniously to
the ground.

He scrambled on top of her and for a fleeting second thought he would win. But
Missy had other plans. She grabbed his arms and wrapped her powerful legs
around his torso. Missy started to squeeze. Her legs crushed the weaker male’s
chiseled ab muscles. Adam struggled for freedom but had few options. Missy
controlled his arms and her legs made it harder and harder to breath.

She noticed Adam’s eyes starting to fog over and decided to back off on the
scissors hold. Missy didn’t want a quick win. She wanted to physically
dominate her boss over and over again. By the she was done with him, Adam
would know who was in charge. Missy also found the wrestling to be very
sexually stimulating. Adam was a good looking guy with a great body. The fact
that she could over power him so easily just added to the excitement.

Missy released the scissors and rolled on top of Adam. Much to her delight,
Adam rolled with her and struggled to stand. She liked the fact that he still
had some fight left in him. Missy allowed Adam to get to his feet while she
entangle his arms in a full nelson.

Adam was elated to be out of the scissors and back on his feet. He incorrectly
assumed he had used his skill and strength to escape his female adversary. Now
he concentrated on breaking the full nelson. But this time fate intervened
against him. As he wriggled to free him self from her powerful arms, Adam’s
shorts fell to the ground. They had been partially dislodged during his
"escape". With his arms trapped uselessly over his head, Adam could do nothing
about his wardrobe malfunction. Fortunately, he had a pair of briefs on to
hide his modesty.

"Hey." Adam said breathlessly, "My shorts fell off."

"What do you want me to do about?" Missy answered as she woman handled the
smaller male towards a wall. The fact that she had Adam partially undressed
made her even more aroused.

Missy positioned Adam in front of the south wall, released her hold, and spun
him around. He immediately tried to push her back but that was a mistake.
Adam’s severely drained muscles lacked the strength to push his female
opponent anywhere. She simply grabbed his arms and pinned them to the wall.

Adam took the opportunity to rest for a second while his mind frantically
looked for away out of this mess. Missy’s arms seemed to be impossibly strong.
He decided to use his legs. He raised his right leg and attempted to push/kick
her back. Missy simply pushed forward so that her entire body pressed against
his.

The full body physical contact between the antagonists lit a spark. Adam could
feel her firm breasts pushing into him. Her soft abdomen rubbed provocatively
against his manhood. Her hot breath washed over his face. Despite his best
efforts, he began to get very aroused. It was bad enough to be defeated by a
girl, but to be visibly turned on by it was too much. He launched a
desperation attempt to free himself from this vixen.

Missy easily contained the weaker male. She never felt more alive and in
control while he appeared fatigued. This differential added to her already
sizable strength advantage. Adam’s futile escape attempt served only to
increase the friction between the two. Missy succumbed to a wave of sexual
desire and kissed Adam full and hard. He resisted for a brief second and then
submitted to her probing tongue.

When Missy finally pulled away, both the antagonists realized their wrestling
had turned into something else.

"What are you doing?" Adam asked with false innocence.

His female conqueror ignored him. She placed both his hands under her right
hand to provide at least the illusion of control. Then she used her left hand
to remove his briefs. Adam’s massive tool sprang to attention as it was
released from confinement.

Missy pushed Adam to the middle of the mats. He watched in fear and desire as
she removed her exercise shorts. The sight of her nude body stifled Adam’s
protests. Strong legs, wide hips, flat stomach and huge breasts encased in
thick female muscles. Her musculature had a soft and feminine quality.

"Fight me." She commanded. Missy wanted to best him one last time.

"No, this has gone too far. We’re both married and need to respect that. Lets
get back to work." He said with as much authority he could muster.

"Hah, you didn’t respect that with Chelsea."

He was stunned. He didn’t think anyone knew about his torrid affair with the
horny hussy working the front desk.

"Now get over here and fight like a man." Missy said.

Adam moved forward knowing what awaited him. His new appendage made movement
awkward. Missy attacked as soon as Adam got within range. She slipped one hand
between his legs, picked him up and threw him to the ground. The hard landing
knocked all the remaining resistance out of him. He quickly surrendered.

"Please, no more." Adam pleaded.

Missy stood proud over the pathetic male. Her breasts heaved with excitement.
The last battle had been disappointing. She wanted more sport.

"Kiss my feet." She ordered. He prostrated him self and complied. She enjoyed
the sight of this once proud young man now paying homage to her.

"Kiss my pussy." She ordered next.

"No, please. Not that. I don’t do that." He pleaded. Adam found it disgusting.

"Too bad." Missy replied as she used her foot to push Adam backwards. She
mounted his shoulders as he lay on his back. "Doesn’t it look good from down
there?"

Her pussy was just inches from his face. Adam could feel her hair on his lips.
Strangely, his inhibitions started to melt away. Before he knew it, he plunged
forward with his mouth. Somehow, it just felt good to be performing this act
of oral devotion on this powerful female.

Missy grabbed the captive male’s hair with one hand to lend support and
guidance. Her other hand found her proudly erect nipples and began some gentle
squeezing. She had never felt this good before. It didn’t take long for the
first climax to shuddered thru her body. Still she felt the need for more.
Missy forced Adam to service her over and over again.

When she finished, Missy slid back a little and looked down at her boss. His
face was covered with her wetness and he gasped for air.

"What about me?" he wheezed. Adam was beaten and broken but still very
aroused. He needed relief.

Missy didn’t hesitate. She slid down Adam’s lean torso and impaled herself. He
felt good inside her. The male reached up and rubbed her giant globes.
Amazingly, she reached the finish line just as he exploded inside her. Both
lay on the ground, gasping, for at least 5 minutes. Then Chelsea paged him to
the front desk.

"I better go." Adam said not knowing what to expect.

"Sure." She replied. Noting that he now needed her approval to leave. Missy
was satisfied in more ways than one.
