CHARACTER RECAP:

Andy - An average looking 16 year old, decent results in school. He is
of average height and is a bit skinnier than most guys his age.

Elsa - Andy's 14 year old sister. She is a mere 142 centimeters (4"8)
and has long blonde hair. Her breasts still haven't grown that much,
but she has a tight body with an unusually round ass for her age.

############################################

A few days later Andy came home from school unusually early. It was
Thursday afternoon and his parents wouldn't be home until 6, which was
more than three hours away. Andy knew Elsa would be home, since she went
to another school, which somehow seemed to always end their days before
his. He had been gathering his courage all week to ask her for another
'cuddling session'. He decided this would be a good time.

When he got upstairs, Elsa was laying on the couch with her macbook.
She was facing away from him, so he saw that she was looking at online
shopping stuff, which wasn't exactly a huge surprise. She was wearing a
white blouse and and a pair of flowery soft shorts.
"Hi", she said without turning her head from the screen.
"Hey", he replied and sat down on the couch behind her.

"So uhm..", he started but lost track of how he had planned to say it.
A few seconds of silence went by, then just as he was about to try again
Elsa opened her mouth.
"39 bucks", she said, making no effort to turn around when she talked to
him.
"That's a lot, I mean it's more than last time", he said.
"Well this Victoria Secret bra costs 39 bucks and I want it.", she said.
Andy thought about it for a while but finally let out an "okay".

"Should we go to..", he started.
"You can do your thing here, I'm not done shopping", she said. She was 
so bold about it Andy thought. Was she really that confident or was she 
as insecure as him? If only she would turn around from her screen he 
could read her face, but she hadn't faced him even once since he came 
home.

At first Andy thought it would be kind of impractical with her laying 
down flat on her tummy, but then the thought struck him, this room 
wasn't dark. This time he was in perfect daylight, meaning he would be 
able to see everything. This made him so excited he didn't even know 
where to start.

"You sure now is okay?", he asked.
"Yeah", she replied while browsing yet another clothing website.
So he carefully put down his hand on her ankles. They were so small he
could reach all the way around with one hand. Slowly he started to move 
his hands up, feeling her smooth skin with his palms. He massaged her 
calves a bit as he was passing. Soon he came onto her thighs, but kept 
moving up until he came to the bottom of her shorts. Surely he was 
allowed to take them off he thought, so he continued moving his hands 
up, past her lovely butt and onto the top of her shorts. 

He grabbed the edge and started pulling them down. No reaction from 
her. Good he thought, pulling them down all the way over her feet. 
Underneath she was wearing a pair of pink panties, which he believed 
was from Victoria's secret as well. She really had a good butt he 
thought, as he for the first time was able to study its shape up close.

He put both of his hands on her butt cheeks and squeezed gently. He 
loved how squishy yet firm it was. After massaging it a bit he moved 
his hands up to her waist. Grabbing her waist with both hands you could 
almost reach the entire way around where it was the slimmest. Her small 
size was one of the sexiest things about her Andy thought.

Grabbing her waist he pulled lightly, as a gesture for her to lift up 
her butt. To his delight she followed his instructions and lifted her 
butt up, standing on her knees with and arched back while still having 
her shoulders and face on the sofa. Andy leaned over and kissed her 
panties by one of her butt cheeks. Then he kissed the other. He was in 
complete worship of her beautiful body.

He kissed the first butt cheek again and started repeatadly kiss her 
while slowly moving towards her pussy. When he got there he could feel 
through the fabric how squishy she was beneath. Her pussy lips must be 
really plump. He continued kissing her by her pussy for several 
minutes, all the while her panties were getting wetter and wetter. It 
was impossible to tell if it was only his saliva or her pussy actually 
getting wet though.

His cock was really twitching now. He decided it was time for his usual 
routine with her thighs. So he pulled down his pants and took out his 
cock. Holding it, he lowered down to get in between her thighs. The 
height difference turned out to be too large though, so he couldn't get 
down between her thighs. So instead he started stroking himself slowly 
while caressing her butt.

His hand moved in a circle over one of her butt cheeks, squeezing it 
every once in a while. As time went on, his circles got larger and 
larger, until his hand started passing over her pussy each lap. The 
fabric really was quite moist and warm. Soon he felt an urge to be 
really close to her again and bowed down with his face against her ass 
again.

He began kissing her pussy through panties again, while also caressing 
her stomach and back with his hands. Then slowly he started moving his 
hands along her body towards her panties. When he got to the edge, he 
grabbed it and waited for a reaction. She gave none.

Encouraged by that, Andy pulled lightly downwards, exposing her butt 
inch by inch. Still she made no attempt to stop him. When he got down 
to her knees, she laid down flat on her stomach and lifted her knees up 
so that he could pull them down further. Then she lifted her ankles, 
allowing him to take them off completely. He threw the panties on the 
ground and turned to her again. Apart from her socks, she was 
completely naked hips down.

He grabbed her waist and got her up on her knees again. He could see 
that she was arching as much as she could, which resulted in her pussy 
being well visible to him. It was the most beautiful pussy he had ever 
seen, with two very symmetrical and plump pussy lips and no hair to be 
seen. Watching closely he could see a thin glaze between her pussy 
lips. She must be at least a bit wet he thought.

He leaned forward and kissed it. It tasted salty. He kissed it again, 
pushing his mouth against it. He started using his tongue to gently 
explore it, tasting the slimy but lovely wetness coming from his own 
sister's pussy. And he had been the one to cause it. Her tasted better 
than he could ever have imagined. He pushed his head more against her, 
burying his face in her pussy. All he could taste now was love and 
youth and sexiness.

Her breathing started to get really intense. He moved his hands towards 
her breasts. He realized she wasn't wearing a bra and figured it was 
because her breast were so small. Coming to think of it he had never 
seen any of her bras in the laundry. Perhaps the one she was going to 
order would be her first one.

As he started playing with her breasts he loved how small they were. He 
hoped she wouldn't grow older anytime soon.

After a while Andy just couldn't wait anymore, he had to get some 
stimulation for his penis. So he got up on his knees and whipped out 
his cock again. If he couldn't get between her thighs, his only option 
would be her pussy. He wouldn't be trying to get inside of her or 
anything that would scare her, but perhaps she would be okay with him 
just grinding the tip against it a bit.

So he grabbed his hard cock and steered it towards her wet pussy lips. 
This was the moment he had dreamed of since he fell in love with his 
sister, and now it was happening. When the tip first touched her pussy 
he got a rush like nothing he had ever felt before. Elsa didn't resist.

Andy could feel the intense heat coming from her opening. As he started 
to slowly move his tip up and down her mound, he realized how wet she 
actually was. Some of her juices even poured out, running along the 
underside of his shaft.

Up and down he slid it a couple of more times, and then paused with his 
tip pointing straight towards her pussy hole.

"If you want to...", Elsa suddenly started.
A few seconds of silence went by.
"...you can put it in just once...", she continued.
"..if you buy me this shirt.", she finished. She pushed the laptop to 
the side to let Andy see. It was a Gucci shirt priced at 29 dollars.

Andy was so horny he would have done literally anything in the world to 
be inside of her, so he instantly responded.
"Yeah whatever you want"
"Okay, go ahead then", Elsa said.
Then she went into an even deeper arch, which angled her ass and pussy
even more up towards him. Andy couldn't believe how hot she was.

He took a few breaths and grabbed the shaft of his penis. The tip was 
already at her opening, so he started to push forward a bit with his 
hips. Despite how wet she was, the hole was really tight, so Andy's 
penis wouldn't go in. He applied some more force, but still he couldn't 
get in.

So he grabbed her around the waist with both of his hands and used the 
grip to force his hips forward. Slowly his penis started to enter her. 
It felt absolutely amazing. She was so tight she must definetively be a 
virgin he thought. Part of her tightness probably came from how small 
she was, her pussy hadn't yet grown into its full size.

When he had gotten the tip in he stopped for a second and realized he 
was so horny that he would basically come from just a few pumps. After 
a few seconds of rest he continued pushing in. When he was half way in 
he realized she hadn't given any sign of pain yet. Either she must 
really be holding it in, or she must be insanely horny not to feel pain 
despite him stretching her pussy so hard.

He continued to push forward more and more until his entire penis was 
inside of her. He was amazed that the entire thing fit into her. His 
tip must be somewhere in height with her belly button by now. The 
sensation he felt in his penis now was almost more than he could 
handle. The warmth, the wetness and just the thought of being inside 
his lovely sister right now, had him on the brink of coming. Her 
breathing was really heavy now, he noticed.

He held it in there for at least a minute, not wanting to pull out as he 
was only allowed to enter once. Then Elsa opened her mouth:
"If you want to be the best and most amazing big brother in the 
world...", she said.
"..You could get me this dress for my prom", she finished, showing the 
computer screen to him. Andy looked at the screen. The dress was priced 
at 229 dollars. He only had about 300 dollars in total, so adding the 
other expenses this would basically render him broke.
"Cause if you are the best and most amazing big brother to me..", she 
began.
"...then maybe I could try to be the best and most amazing little 
sister to you."

That was all Andy needed to hear. Fuck those savings he thought, 
whatever she meant by that thing, it was surely worth all the money he 
had.
"I'll do anything", he said
"Thank you", she said. A few seconds of silence went by.
"So what exactly happens now", he said.
"Well...", she started.
"...I guess the worlds most amazing little sister would let her big 
brother do whatever he wants to do.", she finished.
"So can I?..", Andy started.
"You are allowed to do whatever you want", she repeated.

It took a while for Andy to realize, then he couldn't stop himself. 
With a firm grip around her waist he started pulling out of her slowly. 
When he was almost out he began thrusting into her again. Then her 
repeated the same thing again, a bit faster, then again even faster. It 
felt almost too good, so he knew he wouldn't be able to keep
this up for long.

With every thrust he went faster and pushed harder into her. She began 
letting out feint sounds everytime he thrust into her. Harder and 
harder he pumped, all the while her moaning was getting more and more 
intense. He was beyond the point of no return now.

And then it happened. He started cumming inside of her. Pumping harder 
than ever he just kept emptying more and more semen inside of her. Her 
moaning was really loud by now. Just a few more strokes until she comes 
as well, he thought.

Pumping a few more times, her moaning almost turned into screaming. Her 
body was shaking as she arched and pushed her butt and pussy towards 
him. Then her orgasm subsided and Andy's pumping slowed down.

Semen was pouring out of her pussy by now. As Andy's pumping came to a 
halt, Elsa collapsed down onto her stomach, and Andy laid down on top.

For several minutes they just laid there, breathing heavy as if they 
had just finished a marathon. Then eventually Elsa wiggled her butt a 
bit, as a gesture for Andy to pull out and let her up. As she got up, 
Andy still didn't get even a glimpse of her face. She put one hand over 
her crotch to stop the semen from dripping everywhere and ran to the 
bathroom.

Andy heard her sit down and pee. Shortly thereafter he heard her flush 
and then the door opened. As she came out she was looking at him. 
Finally he got to see her face. And what a face it was.

She was smiling in a naughty and almost devilish way as she walked up 
to him. Andy was sitting up when she stopped right in front of him, 
completely nude for him to see. Then she leaned over towards one of his 
ears and whispered.
"I'm not on any pill", was all she said. Then she giggled and bit him 
quickly in the ear and ran then off to her room.

As her door closed, Andy just sat there and stared. He was completely 
mentally done. This had been the best day he had ever experienced, and 
would probably ever experience. Then the front door opened downstairs 
and Andy woke from his state. Lucky they didn't come home ten minutes 
ago, he thought.
