Testing his sister’s limits. Part: 4

Andy’s 14-year-old sister turns out to be an evil temptress.

CHARACTER RECAP:
Andy – An average-looking 16-year-old with 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 centimetres (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 lying 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 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, and 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 over her feet. Underneath she was wearing a pair of pink panties, which he believed were from Victoria Secret as well. She 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 her butt. To his delight she followed his instructions and lifted her butt, standing on her knees with an 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 repeatedly kissing 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 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 getting wet though.
His cock was 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 on each lap. The fabric was quite moist and warm. Soon he felt the urge to be 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 did not attempt to stop him. When he got down to her knees, she laid down flat on her stomach and lifted her knees 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 intense. He moved his hands towards her breasts. He realized she wasn’t wearing a bra and figured it was because her breasts 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 dick. 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 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 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 dick. 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 tight, so Andy’s dick 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 dick started to enter her. It felt amazing. She was so tight she must be a virgin he thought. Part of her tightness probably came from how small she was, her pussy hadn’t yet grown to its full size.
When he had gotten the tip in he stopped for a second and realized he was so horny that he would come from just a few pumps. After a few seconds of rest, he continued pushing in. When he was halfway in he realized she hadn’t given any sign of pain yet. Either she must 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 dick 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 dick 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 would 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 world’s 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 she repeated the same thing, 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 every time 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 cum inside of her. Her moaning was 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.
Cum was pouring out of her pussy by now. As Andy’s pumping came to a halt, Elsa collapsed onto her stomach, and Andy laid down on top.
For several minutes they just lay there, breathing heavily 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 cum 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 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.
