Andy's Little Sister Grows Up
By San KirkpatrickPicard.

It had been two years since Andy had been home. He'd skipped returning home last college 
break because, well, he needed a break. A break from home anyway. His parents always had 
something to say about him when he was home. He needed to help out around the house 
more. He needed to watch how much weight he was putting on. He needed to be nicer to 
his little sister. Actually, that was the most annoying thing about home, that little sister of 
his.

Cassie could do no wrong in his parents' eyes. Sure, she worked harder around the house, 
studied harder at school and she worked out incessantly, but it wasn't like she did it out of 
the goodness of her own heart. She worked around the house to please her parents. 
Worked hard at school to please her teachers. And worked out for the attention of boys.

He'd always seen it as his place to put her in her place. He was 6 inches taller than her and 
four years older. At 5"10 he thought himself average but still had no trouble giving her the 
occasional sibling bump or slap. His favourite move was coming up behind her and giving 
her a bear hug around the chest and not letting go until she said he was the stronger sibling. 
He felt creepy when as her brother, sometimes his hands or arms would brush her large and 
firm tits as she struggled.

She was attractive. He'd grown up working out with her in the garage gym. He was in there 
maybe every second day. For her it was every day. A day for her arms. A day for her butt. A 
day for her core. A day for her legs. She was so vain. No matter how hard she worked out
though, he was a man and she was just a girl. He was just stronger. He would always start
his workout after her and leave as she was still going. Andy pinched his flabby tummy. Walking
into the house, he thought he'd head to the garage.

He heard a dull clank as he approached. As he walked in, he saw a girl he didn't recognise. 
Four plates drifted up and down as a tall girl made effortless work of a set of bench press 
reps. When the barbell made the familiar clunk on the stand he saw that the plates were 
forty five pounds each. This girl was a beast, whoever she was. She got up and saw him. 
Andy did a double take. This girl was his sister.

She'd grown in two years. She was possibly an inch taller than he was. Her shoulders were 
wider. Her biceps hung from her arms. Her thighs were thick. Her calves bulged.

"Andy? You're home? How are you?" She asked. 

"Fine," he answered. He couldn't think what else to say.

Her blonde hair was a mess. Her melon sized biceps rippled as she redid a pink scrunchie. 

"'scuse the sweaty top." Cassie pulled her top off. She wore a crop top underneath. It 
hugged her broad frame. The loose top had been hiding wide hips and the same tits he 
remembered her having all of her teenage years. They spilled out of a tight crop top. Deep 
crevices framed out the rocks that were her abs.

"How about a hug for your sister?"

Something about her tone made him nervous as she skipped over to him. She seemed 
surprisingly light on her feet given how heavy she must be despite being so slender.

She wrapped him up in a bear hug and lifted him off his feet. The ease with which she did it 
caught him off guard.

"Oh how I've missed you," she whispered in his ear and squeezed tighter. "Remember the 
hugs you would give me?"

"Are mum and dad home," he asked nervously.

"Nope, just you and me. I've been waiting for this."

She jerked a squeeze. It knocked the wind out of him.

"I know you were trying to cop a feel when you used to do this to me you fucking creep." 
She repositioned the bear hug so that the cleavage of her tits brushed against his chin. He 
wasn't sure if she'd meant it or not. At least with the new position he was able to regain his 
breath.

"C'mon, cop a feel, I fucking dare you."

"Ok Cassie, jokes over, let me go," Andy groaned. "It was just a brother sister thing. We 
were just kids."

"You're certainly more than a kid now," she said. She stuck her hands under his shirt and 
traced rough calloused fingers over his stomach. She pinched his belly painfully. She 
wandered back to the bench.

"Ok flabby, let's work." She added two plates to the barbells and lay down. "Spot me 
flabby."

Andy couldn't think what else to do or say so he went to the head of the bench and cupped 
his hands under the bar. She grabbed the bar and panted through 8 reps. His hands never 
touched the bar. She never looked like missing a rep.

"Ok flabby, your turn."

Andy was nervous. This had to be over 300 pounds. He had never attempted over 250. He 
wiggled himself into the best position he could find under the bar and pressed. The bar 
wouldn't move. He pressed with all his might and suddenly the bar gave way as his sister 
pulled the bar up for him, taking about half the weight. With a smirk she slowly lowered the 
bar as Andy pressed with all his might. He tried to fight it back up but he was helpless under 
the weight. The bar touched his chest as Cassie slowly let the weight off the bar.

"Oh brother, you shouldn't have let me get so much stronger than you."

"Cassie, what are you doing?" Andy whimpered.

"What do you need to say?" Cassie amused.

Andy racked his brains for what she was on about. The weight was hurting his ribs. Suddenly 
it came to him.

"Ok, ok you're stronger," he stammered.

Cassie yanked the bar back up onto the stand. Andy tried to gather his composure but 
before he could get up, Cassie flung herself on top of Andy and straddled him. She slapped 
him hard in the face. 

"Remember when you used to do that to me?"

"Ow, stop," Andy whimpered again.

"Remember when I would beg you to stop?" 

She slapped him even harder. His face stung and his eyes watered.

"How many times do you think you've hit me when I was smaller than you?"

Andy didn't know what to do. She slapped him harder still. He grabbed for her but she 
swatted his arm away and slapped him a fourth time.

She grabbed his wrists and wrenched them over his head. He struggled to see through the 
tears that had welled up in his eyes.

"You were basically molesting me, you know that? Every time you were grabbing me. You 
were praying for a bit of tit. Do you know what it feels like to be molested?" 
 
She let his hands go and fished her hand down his pants. She wrapped a hand around his 
balls and squeezed.

"Aargh" Andy screamed. "STOP STOP STOP! Remember I used to stop when you said stop?" 
he begged.

"I guess you did" she pondered. "You should have stayed at college little brother. I grew 
little brother. About half a year ago I looked in the mirror and I just knew I was taller than 
you."

"You've made your point," Andy attempted his firmest, most adult like tone.

"No I haven't actually. You're so fucking lazy. You never did shit around here. Just left it all to 
me and mum. You're just like dad. Dad is such a dog I make him act like one when he 
misbehaves. He'll be home soon. You'd think he'd leave but he's too scared to. I know how 
to make men obey. You'll see."
