Amy, Pt.4  Little Sister Tina  Heather Pt.   
by Musclehead     



Frank awoke to a lot of noise going on out by the garage door. Sitting up and
wiping his eyes, he looked down and saw that he was still erect the next
morning. Only it wasn't the next morning, it was three days later, he just
didn't know it yet. As he sat there on the bed, feeling the aches and pains of
having spent an afternoon with a sexual cyclone, she walked into the room. "Hi
Frank. Man you slept a long time." Just the sight of Amy standing there, even
though she was dressed somewhat modestly in a loose fitting long sleeved shirt
and knee length shorts, still caused him to start ejaculating wildly. "My, my,
little man, you really have no control when I'm around."

Frank suddenly remembered with alarm that his fianc� was due back from a
weekend trip. "Amy, what are you doing here? You have to leave."

"You want me here, Frank. Now that you've been with me, no other woman will
ever do."

"You have to go."

"I'm not leaving. After you passed out from too much sex, I looked around
before I left. I've figured out that you're independently wealthy. I like this
place. I'm moving in. You're my new Sugar Daddy, or should I say Sugar Little
Man?"

"You're a crazy bitch. I'm engaged to be married."

"Not anymore." He froze as the voice of his girlfriend, Wendy, could be heard
from the other room. As she glided in, Amy turned and smiled at her. The
twenty-eight year old woman was a slightly taller than Amy. She was very fit,
obviously looked like she did more than just aerobics, clearly showing some
muscle tone. But she had never touched a weight in her life. She was just
naturally muscular, although she looked like a frail waif next to Amy. "Frank,
I've been back for a full day. It's Tuesday. You've been sleeping for three
days. I've become, shall we say, acquainted with this muscle goddess. She must
have really done a number on you."

Wendy came up behind Amy and started fondling her muscular arms as she talked.
"I'm just fine with her moving in here, Frank. And you're going to put an
addition on with one huge room and twelve foot ceilings. It's going to be a
gym, and Amy's gonna train me and she knows this guy who will provide me with
some of the supplements that he gets for her. I don't know if I have as
perfect genetics as she has, but I'm willing to bet that they're way better
than yours for building muscle. Imagine, two muscle women under one roof
sexually abusing you day and night."

"Abusing me?" He looked over at Amy. "Why? Amy, why? I showed nothing but
respect for your awesome superiority."

"You cheated on your fianc�. If I had known you were taken I would have had my
way with you anyway, but if you were honorable you would have at least tried
to resist me."

"And Amy's going to help me become superhuman too since she said she can't
believe how many muscles I have for not having lifted weights before. And she
dominated you simply because she can and she likes it. I'll be able to
overwhelm you also soon enough, and I have an axe to grind since you cheated
on me, motherfucker."

Just then, Jason backed into the room struggling with his end of a large
trunk. "Some of my clothes," explained Amy. There was a girl bringing up the
other end of the trunk seemingly lifting her end with little effort. "Frank,
this is my little sister, Tina. Wendy met her earlier. She's going to be a
tenth grader this year, four years younger than Jason here. And he weighs in
at about one-fifty-five at five-eight, to her five-two and one-thirty. Yeah,
one-thirty is a lot at that height, but you see, she took to weight training
and crossfit like a duck to water. And yeah, she did gymnastics from a young
age, just like me."

Amy stopped talking for a minute and walked over to Jason, grabbing his tee
shirt and ripping it right off his body. "Now, Jason here has been lifting
weights for almost two years. Hard to believe, huh? That's because he is
rather average." She looked over at her diminutive little sister. "Tina's been
lifting for six months. How about a little entertainment, sis?"

"Sure. Since you told me your new boy toy lives at the beach, I wore my new
bikini. It's very tiny, but I want to wait 'til we're by the beach. I'll just
take off my sweatshirt." She pulled it over her head, and she was wearing a
sleeveless t-shirt. Her shoulders were wide and round and her arms were as
muscular as her legs in her short cut-offs. She then proceeded to wrestle
Jason into submission so easily it looked like he wasn't even trying, although
he was fighting back as if his life depended on it. At the end, Tina put
Justin in a classic backbreaker hold, the same hold that Justin had found
himself in during his first encounter with Amy in the Reynold's pool a few
months back.

Amy looked over at her amazing kid sister. "Ya wanna go for it, babe?"

"Piece of cake." And then little Tina pressed Justin over her head, and it
really didn't seem like it was much of a struggle for her. She held him for a
few seconds and then unceremoniously dropped the poor guy behind her as she
sauntered over towards Frank, who had had the wherewithal to cover himself up
when young Tina had entered the room with the trunk. He had also lost his
boner when Wendy commented about having an axe to grind.

As little Tina stood in front of him with her hands on her hips, her muscular
body pumped from her systematic destruction of poor Justin, Amy bragged a
little about her kid sister. "I guarantee you, Frank, there's not too many
little tenth graders out there like my sister. I told you before that I don't
bench anymore, but Tina does, because she loves it. Hey Tina, how much are you
doing now at one-thirty?"

"Two-ten, give or take."

Amy looked over at Frank with a smug grin on her face as Tina continued to
stand there in front of him in a very confrontational manner. "Huh, two-ten.
Isn't that what you do, Frank? A little tenth grade gymnast is as strong as
you, pound for pound way stronger? How does that make you feel?"

"Pretty average, and I thought I was sort of strong, ... ... ..jeeze."

"Just think about it, Frank. When I was her age, I was about the same height,
and I was pretty strong from gymnastics. I didn't start weight training and
Crossfit until less than a year ago and I think you could say that now I'm all
but unstoppable. And here's my little sister, with basically the same
spectacular genetics and she's got a four year head start on me. She's already
twenty pounds more than I was at that age, all additional muscle, and she
already benches more than I did when I started working out. And she's not yet
taking that stuff that Fred, my boy toy trainer, gets for me. Imagine what
she'll be like in four years. "

"I don't wanna wait four years to beat the crap out of this guy," yelled Tina
as she took two quick steps, lowered her shoulder into Frank's gut, stood,
turned around and dumped him on the floor. She then leaped on him. She had
taken him somewhat by surprise, but no excuses for the guy. He outweighed her
by fifty pounds and she was tearing him a new one. Tina was like a wild animal
and Frank had no chance. She was much faster than him, and she had that
gymnast's flexibility, coordination and balance. Plus, she should have been
the one wearing the shirt that said "extremely aggressive" on it.

While Tina relentlessly pursued all kinds of pain inflicting holds on Frank,
Amy laughed as she told him, "Frank, I forgot to tell you, I assumed when you
said you benched around two-ten, that you meant one time. Tina here does it
about twenty. She just never runs out of energy."

"GET HER OFF ME," he screamed.

"Come on, wimp, fight back."

"Tina, I think he is trying, you're just too awesome. You can give him a break
now." She had been sitting on his back, leaning forward with both of his arms
behind him, one of hers holding them in place. Her other arm was behind her,
pulling one of his legs up farther than it had ever gone before. When she let
go, his limbs flopped down in exhaustion. Tina bounced to her feet, moved away
and started doing this thing where she would basically jump to a handstand and
then bounce up to her feet, going back and forth, back and forth as if it
required no effort whatsoever.

While Tina put on this show of skill and stamina, Amy went over and nudged
Fred with her foot. "I'll bet you never thought that a fifteen year old tenth
grader would kick your ass so easily. Imagine what those high school boys
think. You know, a lot of boys in ninth and tenth grade haven't hit puberty
yet and she clearly has. So under normal circumstances it wouldn't be fair. At
that age there's lots of girls, just average girls, who are bigger and
stronger than boys who are just that, boys. So just imagine how unfair it
would be with our little superstar here."

The whole time that Amy was bragging about her sister, Tina continued to do
those handstand to feet to handstands, but still was able to talk in a normal
voice, interjecting, "Sixteen. Thanks for remembering my birthday, Sis."

"Sorry, Babe, I think I was here on your birthday, showing Frank what it's
like to have sex with a superior human." Frank was sitting up now, indeed
feeling very inferior, which, compared to most people, he wasn't, but ... ...
"So, anyway, regarding boys her age, we don't let her mix it up with any of
them, but they do have this one thing that she does with some of the
neighborhood kids. She lies on her back and then two guys, one each, get her
arm and four guys, two each, her legs. And then they try to hold her down.
They never succeed. Okay, break's over."

Tina went from her handstand, pushing off and crashing directly into Frank. He
was on his back in a split second and she was sitting high up on his chest,
his arms captured under her muscular little legs. Arching her back, she
grabbed his ankles, sat back up and folded him in half as she stared down at
him. Amy was a wild, aggressive woman, and she knew that Tina was following in
her footsteps. But she did want to keep this image in her head of a baby
sister, so she diverted her eyes for a moment, not wanting to see what was
going to happen next. But there was so mistaking his muffled snorts and slurps
and her squeals were certainly not from pain.

After she and Justin left, "Why did you let her do that to me?"

"Did you just hear yourself? What a whiner. You're asking me, why didn't I
protect you, big hundred and eighty pound football player, from a hundred and
thirty pound girl? Ha, ha, what a wuss."

"She attacked me when I wasn't ready."

"Hold that thought. Go take a shower and get something to eat and then meet us
out on the beach."

A little while later, Frank had showered, shaved and eaten something and he
felt refreshed. While he was in the shower, he pondered everything that had
happened since a certain amazon had asked to play football. He beat off while
he was showering, marveling that his cock was indeed now bigger than it had
been three days ago. And while he shuddered at the idea of being sexually
abused by Amy, and sometime in the future by Wendy if Amy's hunch about her
genetics was right, he also knew that his experience with Amy was the most
exciting thing that had ever happened to him. There wasn't even a close
second. Wendy was a great fuck, the best he had ever had, until Amy. So if
Wendy started working out and doing crossfit, it stood to reason that she
might become as sexually awesome as Amy. He was feeling much better about the
whole situation as he made his way out to the beach to find them.

Having masturbated in the shower, he figured that his cock would calm down for
a bit. He was wrong. When he met Amy several days prior, she was wearing that
leotard top and running shorts, and yes, he had seen her bare breasted and
with her running shorts all bunched up, but everything was moving so fast the
night. Today, though, she was wearing another one of her animal skin suits,
the tiniest suit possible, just patches of material covering her pussy and a
little triangle above her muscular glutes. The top only covered her nipples,
and made her breasts seem to jut out even farther than when she had nothing
on. Firm tit flesh was exposed on all sides. She had done a killer workout
before she had come over that day and she was even more pumped than the first
time he had seen her.

Amy was so beyond perfect that she looked like one of the women in those
websites where they had been drawn by artists, that's how far beyond any other
body hers was. Even though she had an extremely well developed core, every row
of abdominal muscles full and rounded, the line down the middle pronounced,
her wide lats, thick upper back, broad round shoulders and those tits blasting
off those pecs, her upper body looked twice as big as her waist. The package
was completed with amazing arms, a thick vein running over her rounded biceps
and full defined triceps. Plus she had those powerful legs that could propel
her close to five feet out of the sand, every head of her quads quite
separated, hamstrings looking like steel cables. She was truly unbelievable.

Actually, there was one body that could match hers. Her little sister, dressed
in a matching suit was just a smaller version of Amy, fully a woman's body at
sixteen, as so many are these days, but with all that muscle. Having breasts
at that age, even big ones, is not uncommon, but for her to have that much
fully maturely developed muscle was even more amazing than the older sister.
Wendy looked spectacular in her bikini compared to any other woman out there.
But she looked like a weak boy next to Amy or Tina.

The crowd that had gathered was watching intently as Amy stood like a statue,
her powerful legs spread to shoulder width, one muscular arm down, but
slightly out for balance and the other straight up over her head. Mighty Mite
Tina was doing one armed handstand pushups on top of Amy's hand, with her legs
slightly flared out and moving around as she cranked out one after another,
with an arm that while not as big as Amy's was proportionally just as thick.

"Jeeze, they really are superhuman," Frank said out loud, though he thought he
was just thinking it.

Some guy standing next to him overheard him. "Man, you got that right. A
little while ago, the smaller muscle chick laid down in the sand on her back,
and eight guys, all somewhat bigger than her, tried to hold her down, two on
each leg and two on each arm. They couldn't do it. Even though they weren't
really fighting, ya know, they were just trying to hold her down and she was
just trying to get away, when her big sister said go, she was so wild in her
efforts to get free that when it was over and she was standing there smiling
triumphantly while several guys were on their hands and knees looking like
they were ready to puke. More than a few of them went away pretty battered up,
bruises all over them. They should have added two guys to try and control her
torso, but even that might not have helped."

Just then, Amy saw Frank. Smiling broadly at him, she spoke loudly so everyone
could hear her, "Hey, everyone, see that handsome, buff guy over there?" Amy
lifted her other arm and pointed at Frank, steady as a rock, Tina up to
probably thirty one armed pushups just since Frank had arrived, and who knows
how many before that. As people looked over, she continued. "He's five ten and
about a hundred and about one eighty, fifty pounds more than my little sister.
Obviously, he works out, though just as obviously, not as much as me, or my
sister. A little while ago, she had a little wrestling match with him and had
an easy time of it. He claimed she had taken him by surprise and that he had
just woken up and was hungry to boot. Well, he's wide awake now, showered and
fed, so she won't be surprising him this time."

She looked up at her sister. "What are you going to do for a dismount, Sis?"

"I'll need both your hands, Amy." Amy extended her arm as Tina brought her
other down. Doing another pushup, coming way down, Amy looked up and gave her
a peck on the cheek, and then Tina blasted off backwards, doing a double flip,
landing perfectly.

Amy came over to Frank. "Are you ready?"

"I'm not doing this."

She turned back to the ever bigger crowd. "Frank says he's afraid. God, he's
half again as big as her." As everyone laughed, she looked to him again.
"Maybe you need some persuading. If you don't wrestle my sister, here and now,
I'm going to strip you in front of all these people, put you in a back
breaker, one of my favorite holds since it's so totally humiliating. I'll
alternate pulling down until you scream and then pressing you over my head.
You know how turned on you get by my awesomeness. Eventually you'll erupt
without any direct stimulus other than knowing that you're completely and
totally under the power of an advanced human being."

"Okay, okay."

"Let's go." They went over to where Tina was standing, rubbing her hands
together. The huge smile on her face conveyed absolute confidence that there
was no doubt about the outcome of this upcoming little wrestling match. She
knew it and he knew it. Frank was a reasonably big and strong guy. He was
pretty buff, but she was totally jacked. There was no comparison in
muscularity and conditioning. He wanted to know what the rules would be, and
would it end with a pin? "No rules for you Frank. You can try anything you
want. The only rule for Tina is that your dick and balls are out of bounds.
And no, the match will not end with a pin. It'll end with total surrender,
when you're begging her to stop, or you're unconscious."

"Or she's begging or unconscious."

"Yeah, right, Frank. Get real, will ya?"

Factoring in age, Frank understood that she was even more phenomenal than her
big sister and he had already felt her strength, whether he was taken by
surprise or whatever. They circled each other, each looking for an opening,
the smile never leaving her face, Frank becoming more unnerved by the second.
He came in a little high and instantly, one strong arm shot between his legs
as the other grabbed his arm. Her grip was so strong that it hurt his biceps,
but he didn't have time to focus on the pain because he was being lifted off
the ground. She straightened up, twisted and slammed him on his back. Before
he could react, she dove and somersaulted over his head, her lower hand
bringing his leg along, flipping him onto his stomach as she was again
airborne, back flipping and coming down on the small of his back, leading with
one knee. This fight was over, or was it?

She could have ended it right there, putting him in some devastating hold
until he screamed for her to stop, but she didn't press her advantage. She
jumped to her feet and strutted around the edge of the crowd with her thick
arms in the air shaking her hands back and forth as she went. As he slowly got
to his feet rubbing his sore lower back, Frank wondered what it must be like
to be so strong and so athletic that you know you can't be beaten, even by
someone quite a bit larger. Tina had that self-awareness in spades. She just
knew she was gonna' kick his ass and that it would be easy.

No rules, he thought to himself as he got to his feet and ran towards her. He
got her into a bearhug from behind as she was still focusing on the gathered
crowd. "Huh, now let's see how cocky you are," he thought to himself. Lifting
her off her feet, he started to throw himself and her back into a suplex, but
with that gymnast's flexibility, she looked over her head, and as they were
landing, she put her hands on the ground. She had simultaneously brought her
legs back and hooked her feet behind his butt, and then she exploded,
continuing the backwards momentum and flipping them completely over so he
landed on his back, with her sitting on his stomach, looking down at his feet.

She grabbed his legs, spread them out to the sides in a v shape and then went
into a handstand on top of his feet. And quickly as she had gone into her
handstand, she pushed off, spinning while upside down, again landing in a
handstand, still using his feet, but now facing the other way. Frank was
sitting up to try to get something going with his arms but she was just too
fast. Powering his feet out to the sides, creating a v with his legs, she
brought hers down and under, in a maneuver that's called "skin the cat", she
was suddenly flying at his upper body, feet first. He had one arm up, and her
legs went around his neck and that one arm before she fell to that side, on
her back, with Frank in a combination head-scissors/armbar. That took less
than three seconds.

He still had one arm free and she had both. But he was using his free arm to
futilely pull on her short, tremendously powerful legs, putting that arm
within her reach. So she sat up quickly, grabbed it with one hand, and the
opposite leg with the other. Showing brute strength far beyond anything he
could defend against, she yanked that leg up and under his arm that she was
holding, and then pulled the arm towards her. Reaching down to his free leg,
she pulled that up towards her and she quickly lay back down.

So she had one arm and his head and shoulders tied up with her legs, the other
arm and one leg caught with one hand and the other leg pulled up and painfully
across his body with her other. It was a dazzling display of skills,
flexibility, speed, coordination, strength and fighting skills that turned
around a disadvantage in seconds. It all happened with such blazing speed and
power that he didn't have time to do anything to counter her, other than his
unsuccessful pulling on her leg. Amy clapped with delight watching the little
dynamo completely controlling every part of his body. It was the most amazing
hold she had ever seen. Her little sister was not only frighteningly strong
and as flexible and coordinated as any gymnast, she was also an absolutely
devastating wrestler.

Frank was in immense pain, couldn't move and was getting weaker by the minute.
And in the back of his pain addled brain he knew that if she could get out of
a backwards bear-hug and have him in this totally locked up hold that easily,
there really wasn't anything he'd be able to do to stop her.

Like so many genetically gifted women, Tina was getting really aroused by her
superiority and as she got more and more turned on, she got stronger and
stronger. Since she had a sizable strength advantage when they started and now
that his pain was weakening him and her arousal was making her stronger, this
was not a pretty picture for poor Frank. Mustering all that power, she was
about to make it worse. Suddenly, she started pouring on the pressure,
squeezing with her legs and pulling as hard as she could with her arms, every
perfectly developed muscle exploding in detail, throbbing with unreal power.

Frank started screaming in agony, but he wasn't surrendering, he wasn't
begging, and he wasn't out cold, he was just screaming, so the contest wasn't
over yet. After about ten seconds, she released all her holds and got up,
standing over him, straddling the poor guy as he lay on the ground, writhing
in pain. Bending slightly at the knees, Tina jumped and back flipped away from
him, curtsied to the crowd like a little girl and went to get a drink of
water. That was the only respite he got. He was sitting as she got back to
him, so she just jumped forward, landing on his chest as he fell again onto
his back. She was tempted to just slide forward and bury his face in her
crotch but that wasn't what she had in mind, at least not yet. No, the
onslaught was about to kick into high gear, with no more breaks for a while.

Gracefully rolling backwards down his body and onto her feet, she reached down
and grabbed his ankles, lifting them and then jumping forward, pretty far, to
above his head. This caused his body to flip end for end, so as she landed, he
was on his stomach. She crouched down, sliding his shins under her armpits and
then applied a Boston crab. Her flexibility was so advanced, that she went
back and back until her head was right next to his. Turning towards him, she
licked his ear and then kissed him on the cheek, laughing as she saw the look
on his face. Clearly he was not used to being bent that far.

Tina sat back up, relieving the pressure on Frank's back and as she did so,
his legs slid some so now the tops of his feet were under her pits. It seemed
like some relief until she reached back, grabbed his forearms and then stood
up pulling his arms back as far as they would go. What a sight, this big guy
being held upside down between this mighty mite's legs as she continued to
apply the pressure. And then she jumped, spread her legs to the side and poor
Frank crashed down on his belly with her dense hundred and thirty pounds on
top of him. As he gasped for breath, she released her holds.

As he lay there, twitching, Tina stood over him, and he could hear her talking
to her sister about how easy it was to destroy this big guy. It was hard for
him to reconcile in his dazed mind how that lilting southern accent was coming
out of the mouth of the brutal female fighting machine that was causing him so
much pain. He vaguely heard her say something about getting back to the
business of destroying this wimp.

Tina turned around, but as always, with a flourish, jumping high, straight up
and spinning one and a halftimes, landing once again straddling his prone body
before sitting down on the small of his back. And then Frank felt strong arms
wrap around his shoulders from behind, capturing one arm. He felt his upper
body being pulled up off the sand even as he was still struggling to catch his
breath. As Tina started to twist him painfully to the right, he felt her right
hand grabbing his ankle on that same side. It was mind-boggling that she was
generating that much squeezing and push/pull force with just one arm around
his shoulders, but she was.

Instead of her usual pulling the leg back, to arch his spine as she went, this
time it was pulled forward so she could bring it farther, all the way until
she was able to grab it reaching across with her left hand that was torqueing
his body in that direction. Now she had his upper body and his right leg under
her control with just her left hand. She clamped her knees to the sides of his
waist, put her right hand onto the ground, straightening her arm and lifting
herself into a twisting plank, her lower half in line with the ground, her
upper half to the side., holding his hundred and eighty pounds up off the sand
and basically twisting him in three directions at once.. She then flipped over
onto her back and started rolling, as she rearranged herself and Frank, so
quickly that no one saw exactly what happened, but as they continued to roll,
they ended up with Frank on his back and Tina sitting on his stomach.

"I thought you might have more of a chance if we were facing each other," she
taunted in that sweet Alabama twang, "even though you still have less than
zero." They grabbed at each other's arms and shoulders, Tina immediately
overpowering him, pulling his upper body up off the sand as her short, thick
legs went around his waist. His legs were free but that's about it. Then the
rolling and thrashing around continued, each time the action slowed for a
second, they were in a new variation in that basic position.

Finally, she had his legs in somewhat of a grapevine, hers being too short for
the whole thing, but still totally devastating due to the power they packed.
His arms were completely stretched above his head as she stared down at her
totally exhausted opponent. Pouring on the pressure put him under for a few
seconds, just from the sheer pain her brutal strength was causing. Now that he
was incapable of any resistance, Tina sat back up, lifting him up to a sitting
position. Then she quickly lay back on his lap, snaked her arms under the
backs of his knees, exploded back up and forward. Frank's arms were useless by
now, totally wasted from the various holds she had had him in over the course
of the slaughter.

As they hung limply at his sides, Tina wrapped her arms around them and around
his back as far as she could reach. Frank was completely folded in half, all
his limbs and his torso in a full body bear-hug. She couldn't generate full
power since she couldn't clasp her hands together, but her strength was so
phenomenal that she was able to elicit screams from Frank with a three
quarters hug. To make things worse, she rolled onto her back and started
flailing around. It was quite clear to Amy what was going on between Tina's
legs. Actually it was much more than that. It was a total body, head to toe
orgasm while taking Frank's poor body beyond totally beaten.

Tina released his seemingly broken body and started walking around the edge of
the crowd again, totally relaxed even as her muscles remained pumped, the
veins so prominent that you could actually see the blood pulsing over swollen
biceps. Someone asked her to flex. "I don't flex. You can see how full my
muscles are without that silliness." Sauntering back to Frank, she started to
walk around his prone body on her hands, going to just one hand every once in
a while, feigning a yawn with the other, to taunt Frank, asking, "Are you
ready to continue, wuss?"

She left him lying there a little bit longer, going over to talk to her
sister. Seeing how utterly easy it was for Tina to destroy this big, strong
guy, Amy was becoming well aware that her little sister was even more
incredible than she was, indeed was a more skilled fighter and could probably
give her a really good match. But right now, this wasn't what anyone would
call a match. It was a rout. And she wasn't done yet.

Frank was just starting to get his shit back together again, kneeling, but
upright. Tina came over to him, standing with her hands on her hips in a very
confrontational manner. "Are you still going to use the excuse that you
weren't ready this time? Have you figured out yet that back at your house I
wasn't even trying that hard and that I am such an awesome fighter that you
have no chance, zero, none against me." This mocking infuriated Frank and he
lashed out and punched her in her rock hard abs. She barely seemed to notice,
just continuing to talk.

"And even if you've figured that out, you still can't understand just how I
can be so amazing. Well, I was strong from gymnastics, along with all those
other skills. And then, my genetics, just like my sister, are so superior that
as soon as I started lifting and doing Crossfit, my strength mushroomed. As to
my fighting skills, believe it or not, I just improvise, that's how fucking
incredible I am. Oh, yeah, I lied when I said I benched two-ten. What my
sister said was closer to the truth, two-ten for twenty reps. I can actually
do more than two-sixty, more than twice my bodyweight."

Amy's mouth dropped open at the last comment, not having known previously that
her little sister was almost as strong as her, probably stronger, pound for
pound. "So, Frank, you thought you were a pretty strong guy, benching forty
more than you weigh, but you are a weak pussy compared to me." While his mind
was still spinning from the realization that his hardest punch didn't faze
her, hearing the word pussy, and remembering that Amy said he had no rules, he
suddenly hauled back to punch her again. As she laughed, he slammed his fist
into her pussy and she doubled over in agony. Jumping to his feet, he brought
a knee up to her chin, knocking her backwards. She fell to the ground on her
back, clutching her crotch as Amy ran forward. Frank pointed at Amy, shouting
"You said I had no rules." She backed off as Frank jumped on Tina's hard
midsection, catching her arms as well.

Her eyes were open, though somewhat glazed, but in spite of her pain, she saw
the fist coming towards her face, and with that incredible quickness that only
the best athletes have, she moved her head and his punch only grazed the side
of her face. In the meantime, she had been massaging the pain in her vagina
with her trapped hands and suddenly the pain turned to intense pleasure and
power surged through her as she arched up lifting his weight off the ground
with her as she had an intense orgasm.

Still in the throes of her pleasure, she flipped to the side and instantly he
was on his stomach and she was on her feet. If she was overwhelming before, it
was about to get a whole lot worse for Frank. She was just having fun up till
now as she demonstrated her devastating fighting skills, but now she was mad.

Frank started to get up and Tina flew at him from behind, spreading her legs
and wrapping them around his head and neck, right above her knees as she
landed gracefully on her feet. Immediately, she threw herself backwards,
arching and going into a back handspring. She kept his head locked between her
powerful lower thighs and her hands went to his ankles instead of the ground.

When she completed her move, wrenching his neck and causing his back to arch,
she continued to roll until she was upon her shoulders. His shins were on the
ground, her strong hands still on his ankles, her legs were up in the air, his
head and neck still captured, and he was being bent backwards and stretched
out at the same time. As he screamed, Tina continued to bring her legs back
over her head into what is known in yoga as the plow position. He was totally
bent in half, the wrong way and screaming for mercy. But he would get none.
Simultaneously, she let go of his ankles, and snapped her legs even farther,
throwing him over her, releasing at just the right point so he went flying,
She kipped to her feet, leaped high and back flipped in his direction. He was
still aware enough to see her hovering upside down over him and he put his
legs up to protect himself.

In another incredibly athletic move, she caught herself in a handstand once
again on his feet. And then she brought her arms out to the sides into what
can only be called an upside down iron cross, pushing his legs out with her
arms. After holding that position for a few seconds, she finished off her
flip, landing on his face, looking at his torso and feet, her legs completely
out to the sides in a full French split. Leaning forward, she once again
grabbed his legs at the ankles, but with her arms crossed, so when she brought
them back to their normal position and towards her powerful torso, she brought
each leg to the opposite side, crossing them and causing his entire body to
twist. Once again he was screaming his surrender but it wasn't happening. No
one was intervening from the crowd. First of all, everyone there knew that
there was only one person who could stop this slaughter, and that was Amy. And
second, everyone saw him punch her in her pussy, so no one was feeling sorry
for him.

That should have been the end of it, but she wasn't done. It must be
remembered that she almost never ran out of energy and was still going strong.
She was extremely worked up and her strength had increased to the point where,
over the next few minutes, Amy felt that in Tina's present state, the only way
Amy would be able to get the better of her sister was if she was just as
turned on.

Indeed, she was very aroused watching this little fighting machine, but not as
much as the girl who was doing all the damage to the big guy. Amy looked over
at Wendy and could immediately see that she was similarly turned on by the
awesome strength and fighting skills that little Tina was exhibiting. As a
matter of fact, Amy was considering, much the same way she forbid Tina from
fighting boys her own age, she might have to stop her from fighting even guys
as big and strong as Frank.

Frank was pretty much defenseless at this point, but Tina didn't care. After
all, she knew before they even started that she was going to kick his ass
without much fuss. So now the real brutality was about to commence. Still
holding his ankles, his body in that twisted position, she slid off the back
of his head, but remained in a split. And then she fell backwards, a yanked
with all her might, whipping him up over her, his body untwisting in the
process and crashing to the sand above her, face down.

She got up and walked over to him, a well-deserved swagger in her step.
Grabbing him by the armpits, she stood him up and quickly, since he was so
wobbly, she bent forward and lifted him across her shoulders in a classic
backbreaker. She pulled down hard, but he barely responded, he was so out of
it. So she decided to show off for her appreciative audience, pressing him
over her head about fifteen times, something she could do any time, but as
turned on as she was, she was making it look easy, because it was. Finally,
she dropped to one knee and at the same time, swiftly brought him down across
her thick thigh, effectively a six foot fall. That got the response she was
looking for.

But she was immediately up again, Frank across her chest. She jumped and
twisted, adding torque as she slammed him down with her concentrated weight on
top. Up again, and another twisting suplex. The next time, she went straight
back, completing a three quarters back flip with the same devastating results.
With each slam, she was getting a little farther from the crowd and a little
closer to Frank's beachside house. But the crowd started to follow, so amazed
to see a hundred thirty pound muscle girl not only lifting her hundred and
eighty pound victim, but actually jumping with him and twisting, spinning,
what have you, and crashing him to the sand. Doing it one time would be
unbelievable enough, but she was up to fifteen.

Finally, Amy, having figured out what was going on, turned to the gathered
onlookers. "Okay folks, show's over. I thought I was a bad ass, but my sister
is even more amazing. And I'm real, real aggressive, but I think this guy
found out to never fuck with the likes of her again." As the crowd dispersed,
everyone except Wendy, Amy turned around and caught the last glimpse of Tina
running towards the house with Frank slung over one of her shoulders.

When they got back to the house, Frank was lying on the bed naked, his huge
dick sticking up in the air, his hands and feet tied together with Tina's
bathing suit. She was taking a shower, and she didn't want him to wake up and
try to get away while she was still cleaning off. He was soaking wet because
she had dumped him in there and run cold water on him. Even that didn't revive
him.

Amy went into the bathroom. "What's your plan with our weak little stud here?"

"I'm gonna make him lick my pussy for about five hours. I shouldn't have
cleaned up. He deserves to have a salty taste in his mouth. But the way I feel
right now, I'm probably going to drown him in girl goo."

"Well, Wendy was so turned on watching you kick his ass, and she really likes
my body, so I might be giving her a large dose of feminine juices as well.
Course, I'll return the favor."

"Not me. He's getting no pleasure out of this."

"Well, I don't expect you to go down on him, but you might want to fuck him.
He's got a thirteen inch cock on him. Maybe due to the fact that you've proven
to him today that you're superhuman also, maybe it grew some while you beat
the shit out of him."

"Wouldn't he be getting pleasure out of that too?"

"Oh, little wild sister, I'm glad to see that there are some things that you
don't know yet, even though you're now beyond the age of consent. And once
again, sorry about missing your birthday. Just stay in here in the shower for
a few minutes more. I'll be right back."

Amy came back a few minutes got undressed and got in the shower with her
sister. "Tina, you were absolutely stunning out there. I could tell that you
were getting stronger and stronger the more turned on you got. At one point, I
was thinking that you could give me a run for my money."

"Let me start taking that stuff you get from that Fred guy and I won't even
need to be that aroused."

"Are you saying I have an advantage?"

"Yes."

"Okay, I'll get some for you too. What about my size advantage?"

"I think I'm stronger than you, pound for pound. I'll probably gain five or
ten pounds of muscle with that stuff and then I will clean your clock, Sis."

"Oh, you are one hot little momma." Amy moved so close that their breasts
touched since she was leaning forward a little to try to playfully intimidate
her sister, which was not gonna happen. And then her finger went to Tina's
pussy. She let out a moan and the juices started flowing.

Suddenly, Tina felt something being inserted into her vagina. "Oh, God. What
was that?"

"A cucumber."

"It's so cold. It feels wonderful. Move it in and out."

"Okay, but when I see that you're on the verge of coming, I'm gonna say the
word "now" and then as your hot little box starts spasming, I want you to
clamp down as hard as you can. It will intensify your orgasm." It didn't take
very long as Tina was already on the edge. A few seconds later, "Now."

"Eeeeewwwwwwwoooohhhhhh., For well over a minute. "Oh that was awesome. I'm so
wet and sticky."

"That 'cause you crushed the cucumber, and that's how you'll prevent Frank
from having any fun."

"Ha ha. I guess that'll hurt quite a bit, but I don't want to kill him."

"You won't, but remember he punched you in the crotch. The least you can do is
return the favor, pain-wise, while you make your orgasms even more exciting
than usual." The sisters came out of the bathroom arm in arm, two perfect
powerful bodies, one smaller but just as awesome. Frank was awake and as soon
as he saw them, he started spouting like a geyser. Tina turned to Amy,
whispering, "we can't have him getting any more pleasure, none."

An hour later, Amy and Wendy took a break from their girl lovin' to peek in on
Tina. She was half kneeling at the foot of the bed, one powerful arm holding
her up, her thick upper back arched, her round boobs sticking out. Her other
hand was pinching a nipple, her eyes closed and her mouth open in a silent
scream of ecstasy. Frank was on the floor beneath her, his head on the edge of
the bed, bent back and engulfed in pussy. His hands were on her muscular
thighs as he had already succumbed to goddess worship but he was getting
nothing out of it because she had her suit bottoms tied tightly around his
dick.

Amy laughed out loud. No, just like Tina said, he would be getting no pleasure
today. The women went back to their lovemaking and a little while later the
heard from the other room, Tina squealing with delight as Frank let out a
muffled cry. They were on the floor now. She was sitting on his face and
needing only one hand to hold both of his arms above his head. Her other was
tugging on one string of her suit bottoms as the other end continued to be
tightly tied around a cock that was so full of blood, it was purple and it
looked like it was going to explode.

Amy took a minute to look at Tina's fine body. Just like her, Tina's abs were
full and each row rounded, The way she was perched on Frank's face was causing
them to jut out, curving down to her detailed leg inserts and up and in to
gravity defying breasts that simply exploded off her chest. Her thickly
muscled back tapered down and in to pronounced dimples and then out to round,
hard glutes. Even though, as she had told the person down on the beach that
she never flexed, right now, holding his arms down emphasized the detail of
her thick triceps and pulling on the string suit bottoms tied to his dick
caused her bicep to bulge, the pulsing of the blood through the vein could be
seen from across the room. Her legs which were resting on either side of
Frank's torso looked so powerful they could squeeze in on him with very little
effort and break his ribs.

"God, she's so hot," thought Amy, "and she's so far beyond what I was at that
age. She sure knows how to use a guy for her own pleasure. I wonder if she was
sexually active before her birthday."

"Well, she's sure an expert now, isn't she?" Amy looked over at Wendy.

"Did I say that out loud?"

"Yup. Come on. Let's leave the two lovebirds alone. Ha ha."

A little while later, it started becoming really noisy between Tina's squeals
of delight and Frank's cries of pain, plus a lot of banging. Amy and Wendy
decided not to peek in anymore, as they were really getting into each other
and the sounds were enough to clue them in as to what was going on in the next
room. When it finally quieted down, a high pitched voice asked, "Why aren't
you guys checking up on me anymore?"

They quietly stole into the room. Tina was standing there with her legs spread
and her hands on her hips and Frank was literally hanging from her pussy, his
body limp, legs dangling behind her and the rest of him in front. He was
completely out of it but had a somewhat serene look on his face. "I think he's
had enough, don't you?" She relaxed her vaginal muscles and he crashed to the
floor, his cock covered with blood.

"Oh my God, Tina. You broke it."

Maybe, but that's my blood. Just lost my virginity to his monster." Just then
the unconscious Frank's dick started spurting like he had been holding back
for a year. "I guess it turns him on being used by a superior being. And I am
a superior being if there ever was one."

"And a little arrogant?"

"Oh, come on Amy, like you aren't?"

"Yeah, you're right. Well, fuck 'em. Arrogance with nothing behind it is
unacceptable, but us, US?"

"Anyway, I'm gonna wash this loser's fluids off me ... .?"

"What fluids, I thought you didn't let him come, well, until that last one."

"I didn't, but he was sweating up a storm and then there's all that saliva.
Anyway, I'm gonna wash up and then head back to the water and see how many
boners I can cause just by walking down the beach."

"No fighting."

"No, my next fight will be with you and you will do about as well against me
as Frank did today."

As Tina strutted off, Amy somehow had a feeling that she was right.
