HEATHER
By Amazonfan
What happens when Tom meets his new stepsister and discovers she's far bigger and stronger?


Tom's widowed dad was transferred to California, met a rich 
woman out there, and the next thing Tom knew his dad went to 
Vegas one weekend and got married.  Tom was away at his 
senior year in college so the first time he was to meet the new 
wife was during break.  His dad had moved into his wife's ritzy 
house.  She had one daughter, a college freshman.Tom will 
never forget the first time he met her.  His new 'sister' was 
catching some rays by the pool.  This gorgeous blond started 
up off her chaise and just got taller and taller.  Stepsister 
Heather was six feet tall - and big!  But not fat, even though 
she probably weighed 175.  One look and you knew she was 
solid and in incredible condition.  He asked her to give him a 
tour of the house.Heather wasn't too friendly.  She came to one 
closed door and said "That's the gym.  It's got everything.  If 
you use it, there's one rule.  It is absolutely positively off limits 
to you when my girlfriend Claire and I work out."  She stared 
coldly at him and then looked contemptuously at his 5'8", 140 
pound body.  "No one will believe you're my 'big' brother," she 
laughed.Human nature being what it is, you tell someone 
something's off limits, they only want it more.  So Tom had to 
find out what was so special about the girls' workouts.  First he 
saw Claire.  She made him feel smaller than Heather.  Claire 
was 6'3" and 190 pounds.  He hung around outside the gym 
during their workouts.  After he figured out their schedule, he 
went into the gym before they got there.  They walked in and 
Heather told him he'd have to leave.  As Tom was protesting 
that it was his house too and she couldn't just kick him out he 
felt two arms grab from behind.  Claire picked him up and 
carried him out of the room.  The door slammed and locked 
behind him.  The girls laughed uproariously.The next day Tom 
hid in the shower room adjoining the gym.  By standing in just 
the right place he could look in a mirror and peer into the gym, 
minimizing the chance of being seen.  He waited until he 
thought they were well into their routine before daring to move 
into position.  He peeked into the mirror and gasped.  Claire 
was stark naked, bench pressing 200 pounds!  Heather's back 
was to him.  She was doing barbell curls.  He couldn't see how 
much she was lifting, but it looked heavy.  She was topless, 
with just a thong bikini on.  Then she turned and put down the 
weights to go spot for Claire.  He couldn't get over how 
muscular they both were - everywhere.  Their arms and legs 
were so huge compared to his.  And their breasts!  So firm they 
just stood straight out.  Tom got an instant hard-on.Claire 
finished her set and sat up.  She glanced into the shower room 
right at the mirror.  Their eyes met for a millisecond.  Tom 
ducked out of the line of sight.  He didn't hear anything from 
the other room, except for the door open and close.  Maybe 
she hadn't seen him.  He peeked back in the mirror.  Heather 
wasn't visible.  Claire was sitting on the bench doing dumbbell 
curls.  Her biceps would balloon and harden into a huge mass 
of muscle as she did her reps.  He heard the door open and 
close again, followed by the unmistakable sound of the lock 
clicking.It was Heather, carrying two beers.  "I was right," she 
said,."Nobody's home."  They both laughed and then chugged 
down the brews.  "Ready?" Heather asked.  Claire nodded.  
Heather raised her voice, "Get your sorry butt in here or we'll 
come get you!"  Tom ducked in a corner and froze.  He heard 
footsteps coming behind, followed by Claire's laughter, "You're 
little.  You think you're invisible too?"  Two hands grabbed the 
back of his neck, pulled him up and spun him around.Claire 
bent over and hoisted him effortlessly over her shoulder and 
carried him into the gym.  She dumped him in the middle of the 
floor.  Both girls stood over him.  "I told you never to come in 
here," Heather intoned, "because we like exercising in the 
nude.  We don't want a horny geek gawking at us, clothes or 
not.  Besides you'd only get in our way.  You chose to break 
my rules.  So now you pay the price."Tom scrambled to his feet 
and bolted for the door.  But it was a key lock.  He was 
trapped.  He turned around and the two of them were just 
standing there smiling.  Heather held the key in her 
hand."Looking for this?" she asked,  "It's right here."  Claire 
went to a weight stack and pulled down on a lat bar, lifting the 
full stack.  Heather put the key underneath and Claire let the 
weights back down.  Heather said, "Now you know where the 
key is.  If you can get it, you can leave."He walked over to the 
machine and grabbed the lat bar and tried pulling down.  He 
could barely budge what Claire had lifted.  With all his might he 
raised the stack up, but then he realized he'd have to be able 
to lift it with just one arm in order to pick up the key.  Tom gave 
up and let the lat bar go.The girls laughed.  Claire said, "His 
brain's as weak as his body.  Let's do it."  They spread apart 
and started coming towards him.  He had to try to stall."I'm not 
lifting a finger against either of you," he said, "You're both 
girls."Heather proudly thrust her 42 inch chest out and 
chuckled, "Oh did you just notice that?"  Then she flexed one 
massive biceps.and asked, "Or are you afraid of this?  
Whether you defend yourself or not, I'm still gonna trash you.  
So you might as well try."Tom stood still, hands at his sides.  
Heather stood before him, bouncing lightly on her feet.  "You're 
a wimp," she said beginning her verbal assault, "A skinny little 
chicken shit wimp."  SMACK!  She slapped him hard across the 
cheek.  SMACK!!  She backhanded him.  She had such power 
he almost lost his footing."You're nothing like you're father," 
she continued, "He's old, but at least he looks and acts like a 
real man.  Were you a little mama's boy?"  The mention of his 
dead mother infuriated Tom.  He leapt at Heather to strike her, 
but her hand grabbed his wrist and blocked him in mid-
swing."So much for not lifting a finger," she smiled.  She 
wrenched his wrist around behind his back, twisting his poor 
shoulder socket.  She pulled up so high she had him on 
tiptoes."AARGH!" Tom grunted, "Take it easy!""Oh, so you 
think you can give orders here?" asked Heather, "You want 
anything, you'll have to beg for it!"  Tom reached back with his 
free arm to try to grab her head and flip her over him.  But 
Heather was much too strong and heavy to fall prey to that.  
She applied a tight full nelson, lifted him off the ground and 
began swinging him from side to side.  Tom was afraid his neck 
would snap.Heather kneed him in the center of the back and let 
go.  Tom slumped to the floor in pain, feeling like he'd been hit 
with a battering ram.  Claire took over from Heather.She 
reached down and grabbed the collar of his shirt.  RIP!!  In the 
blink of an eye she had reduced it to a rag on the floor.  "My 
what an impressive physique," she said mockingly, "I can't 
describe the fear I have when I see you."Claire bent down and 
picked Tom up under the armpits.  She wrapped her immense 
arms around his middle and began to squash him with a mighty 
bearhug.  Tom didn't know which was worse - not being able to 
breathe or knowing he was a nearly helpless toy in her 
arms.What he didn't anticipate as he struggled to break her 
potent grip, as his hands fought against her rock-hard muscles, 
were the pleasurable sensations in his groin.  He looked down 
from his precarious perch in her arms to see her firm 46 inch 
breasts pressing against his crotch, obliterating it from view.  
Looking down was a mistake.  Seeing what was happening 
only intensified what Tom was feeling."Oh God you're hurting 
me, please put me down," he pleaded.  Claire dropped him to 
his feet and shoved him backwards - right into the waiting arms 
of Heather.  She scooped him up around the waist and bear 
hugged him again, this time from behind.  Tom's stomach felt 
like it was being squeezed against his backbone.  Claire 
spotted the bulge in his shorts."Heather, you won't believe 
this," she exclaimed, "But the little pervert is enjoying this.  
Looks like he's ready to rip through his shorts.""Well then, let's 
just rip them off and see what all the excitement's about," 
replied Heather.  She nodded to Claire to come forward, since 
Tom couldn't do anything to stop them.Claire came a couple of 
steps forward and Tom kicked out at her to try to keep her 
back.  But she was so fast she caught his foot in mid-kick.  She 
twisted his ankle until he screamed."You seem to forget there's 
two of us here and either one of us can break every bone in 
your scrawny body," Claire said, "So cut the kicking crap."Tom 
stood still, knowing it was foolish to try stopping her.  Claire 
stood before him and slipped her fingers inside the waistband 
of his shorts and underpants.  She gripped them firmly and 
stared right into Tom's eyes, enjoying the fear she saw there.  
Then she yanked them off.Heather watched Claire step back 
and look down.  The surprise registered clearly on her face as 
she muttered, "Who'd have guessed."  Tom wasn't hard 
enough to be erect, but he was swollen enough to show Claire 
he was very well endowed.  Heather turned Tom around so she 
could make her own inspection.  She was quite surprised too.  
And turned on."Well this changes things, doesn't it," Heather 
said, "All I wanted to do was kick his butt, but now it's obvious 
we can use him for more than just a punching bag."  She 
stepped out of her panties.  "Listen wimp," she addressed Tom, 
"Just so you don't get the wrong idea.  Anything Claire or I 
choose to do with you is solely for our pleasure, not yours.  
You're our slave and you'll serve us as long and as often as 
your performance satisfies us.""No fucking way!" Tom replied.  
He started for the door, forgetting it was locked."An amusing 
choice of words," Claire said smiling as she stood in Tom's 
path, hands on hips.Tom threw a slow short left hook at her 
stomach.  She made no attempt to stop the punch.  His hand 
thudded against the steel wall of abdominal muscle.  Claire 
smiled.  Tom spun around to retreat and there was 
Heather."Let's make a little Tommy sandwich," she called to 
Claire.  Both girls linked arms and pulled together, with Tom 
trapped in between.  As they pulled tighter Tom was squashed 
by the unyielding force of their hard muscles."Do you like slam 
dancing?" Claire asked Tom.  The girls pulled apart only to 
slam Tom from both sides.  They repeated this maneuver 
several times until a dazed Tom slumped to the floor between 
them.  Claire sat straddling Tom, bouncing all 190 pounds of 
female power on his chest.  Tom begged her to stop.She 
gazed down at Tom and could see the defeat registered in his 
eyes.  Proudly she flexed her prodigious arms and leaned 
forward.  "See my arms, Tom?" she said, "Yours are half my 
size.  These are the reasons you'll do whatever I say.  Won't 
you?""God they're so big!" Tom blurted out, surprised at 
himself that he'd admit his feelings to her.  He feared that she 
enjoyed his fear.  But her muscles were exerting a hypnotic 
effect on him.Claire stood up and Heather slid into her place 
on Tom's chest.  She rolled sideways and slid her legs around 
Tom's chest.  "And these are the reasons you'll do what I say," 
she said pointing to the stupendous mass of her thighs, "I'm 
quite sure I could end your life with these."  She tensed her 
muscles, using only half her strength.  Tom experienced a 
crushing force unlike anything he'd ever felt before.  He very 
nearly passed out.Tom grabbed at her thighs in a futile effort to 
spread her legs apart.  Her steel coiled muscles were so hard 
his fingers could hardly make an indentation on her skin.  She 
slid behind him and slapped on a full nelson.  Then she hook 
her legs over his and spread him apart.  Claire knelt down 
between his legs."Give him a couple of squeezes," she told 
Heather, whose thighs collapsed Tom's aching sides."So Tom," 
Claire said, "In lab at college they teach us about empirical 
evidence.  You know what that is.  Well the more you see and 
feel our muscles, the more aroused you get.  Is that proof you 
want to become our little slave and worship our strong, 
superior bodies or what?""No, it's not true!" protested 
Tom."Tom, stop trying to deny your true feelings," Claire 
continued, "Just take a good look at me."  Claire raised her 
arms up in a colossal double biceps pose, twin 18" peaks of 
power exploding in front of Tom's eyes.  "We're all muscle, 
Tom," she cooed, "All outrageous strength and endurance, far 
beyond your limits.  You'd do anything for either one of us in 
the hopes that we'd take you.""He's as erect as a flagpole," 
Claire told Heather, "and almost as big.  How'd such a wimp 
end up being so well hung?  I doubt he'll ever last long enough 
for the both of us?  What do you want to do?"Heather pulled 
back and pinned Tom to the floor.  "Talk about getting pumped 
up," she said to Claire, "You got him that big, you might as well 
enjoy it.  I'm just going to sit on his face and find out if he's got 
any other talents."  She pinned his arms between her thigh and 
calf and lowered herself onto Tom's face.  "Pleasure my pussy 
Tom," she ordered."Just don't smother him to death," cautioned 
Claire as she positioned herself above Tom's tool and lowered 
herself in one slow smooth slide.Each girl stared into the 
other's eyes and saw the rapidly increasing excitement and 
pleasure.  Moans filled the room as they used Tom for their 
intense, multi-orgasmic pleasure.  The powerful spasms of 
Claire's vagina eventually milked a powerful explosion from 
Tom.  But Tom felt nothing, having passed out from Heather's 
suffocating pressure.Sated, the girls dismounted Tom.  They 
retrieved the key and unlocked the door as Tom was coming 
back to his senses."Tomorrow.  You come back," ordered 
Heather, "Or I'll sneak into your room in the middle of the night 
and scissor you till I feel bones break.  Now haul your butt out 
of here.  We're going to shower."Tom grabbed his things and 
scurried for the door.  As he closed it behind him he heard 
Claire remark,"Fucking great workout."  Both girls laughed 
uproariously.
