Treehouses are for experiments Part one by L King

This all started back when my mother split from our father given my father was involved in organized crime back in New York my mother probably rightly assumed he would sooner off her than allow her to leave. As much as sometimes me and my twin sister wonder at what kind of life we’d be living if my mother had opted to stay, he was very abusive towards my mother and had hit out at us from time to time. The last straw was when she miscarried due to the severity of a beating he had given her. He was always repentant after each beating but nothing ever changed. One night whilst dad was out my mother got us out of bed and into a car a sympathiser had given her for her escape.

She didn’t stop driving till we were on the other end of the country, some sweaty middle of the nowhere town in Florida where the flies outnumbered anything else, even grass. I say town but even then we were in a house just outside of it, giving us a slight walk to school for lack of a better term. I think there were about 8 kids at it but as we grew up we were then given a bus ride to a bigger town for school. My mother took a job as a cook at a bar which isn’t as bad as it seems. She was out of the way of the public for the most part and loved her job. She had plenty of money stashed away but really didn’t want to stash the cash for fear of the attention it would bring.

My sister Jane and me Mark were dark haired its hard to remember what our father looked like but we both remember the dark hair that was always slapped back. Given we spent most of our free time in the countryside looking after animals and my mother’s small garden as she referred to it, it was more of a mini farm. We were both strong and thin. Our free time was pretty much me and my sister messing about in the open country near the town. Nothing but climbing trees and playing silly games to occupy two teenagers during the time off.

Being twins we always got on and silently loved being in each other’s company. My sister was super adventurous and usually the first one to get us in trouble where I was more reserved but able to think our way out of it. It was her idea to build the treehouse and after a few shitty attempts I got the hang of it and we had pretty much the best den anyone could believe honestly, some people live in worse accommodation than that thing.

Anyway we hadn’t long celebrated our birthday finally 18 years old our mother allowed us to take some beers when we went camping from now on. This seemed like a great idea… until you were drunk 30ft up in a treehouse after the first time we made this mistake we saved the beers for the night when we were sure we didn’t have to come down. This gave us the added problem of drinking them in a short space of time… I guess right now i’m coming up with excuses but it’s pretty much inexcusable what we did… I still blame her though lol

We were drinking one night in the tree house at sunset and with the lamp set up in our room it was a great night. We read comics, talked about nothing really and even discussed the type of beer we were having it was pretty strong this time and we had more of it thanks to some left over birthday money. We were really easy in one another’s company you know?

Jane – Hey, uh Mark… uh

This was really odd for her and that grabbed my attention when i looked up, i got the impression she was building herself up for something.

Jane- uh.. Have you done anything with…. You know the girls at school yet?

She looked embarrassed and looked away taking a swig of her beer.

Mark- uhm… what girls do you mean. Theres only you and a buncha brats that i’d get arrested for looking at.

This wasn’t entirely true I was still referring to school as the little school we attended in town not the school they had been driving us too.

Jane- I mean at high school… the girls there are pretty

Mark- I guess… but we aren’t really given a chance we are bussed in, in time for class and immediately out or mum needs to collect us… when would we have time.

Jane- Still a virgin then?

Mark- Yup, and I suspect you are too, no?

Jane again looked away embarrassed but I decided to push her a bit

Mark- You ever even kissed a boy?

Jane- no, its kind of sucks. All the girls ever talk about is kissing boys and you know other stuff.

Mark- we’ll get out of this shit pit one day and you’ll be able to suck all the faces you want sis.

Jane laughed at that

Jane- you not worried you’ll suck at it when the time comes.

Mark considered this for a while. He hadn’t really thought of it until now.

Mark- I see where you’re coming from but like what can we do?

In my defense I thought she was gonna come up with a plan to get us into the city for a day or two and try to find a couple of hookups. Instead Jane came over, sat beside him and smiled.

Jane- this is gonna sound a bit strange but… if know one ever knows why don’t we… practice together.

Mark was shocked it took a couple of seconds to register what she was suggesting, in which time she was really close to him and he could smell her sweet perfume see her lips glisten.

Mark- you sure?

Was all he heard himself say before they came together in a kiss and it was a good kiss he put his hand up her back to her neck to the back of her long black hair, He felt himself stiffen and really wanted to do more but knew they were on thin ice. When they parted she looked at him, smiled and inhaled a bit. Mark could see she was flushed in the face but she looked like she always did before she did something… impulsive.

Jane- That was great, can we try with a little tongue next?

Mark- I… dont really know how…

Jane- Neither do I Mark… that’s why we practice

With that she brought her lips to his and they kissed and again but this time she flicked a little bit of tongue into his which was nice and he was sorry he missed it. The next time he met her in the middle it was a bit funny at first and then as they got more comfortable she went deeper and he did the same. They broke and she giggled a little excited giggle.

Jane- That’s actually really nice, I can see why the girls talk about it now.

Mark- I dont think you have anything to worry about, you kiss like that all the boys will be lucky guys.

Jane- you’re not so bad yourself kid (laughing)

Mark laughed along at it and then Jane stopped, seemed to decide on something, took another swig of her bottle then moved again towards Mark. She kissed his lips at the same time as grabbing his hands she guided him from her hips up her body slowly and before mark knew what was happening his hands were on her tits.

It was the first time Mark had stopped to think if this was going too far but that thought lasted only a second after their lips parted. He saw her face with her eyes close biting her bottom lip clearly enjoying the sensation. Mark took control of his hands again and began to really play with her. She opened her eyes and let his hands go as he continued. She lifted her top up over her head to reveal her perfect handful of boobs. Her nipples were pink and she had natural tan lines.

Mark- God they are beautiful!

He raised his hands back to them and she excelled as he felt them with his bare hands he felt her nipple stiffen at his touch and really began to wonder what it would be like to lick and suck on them Mark suddenly decided to take a little leap of his own and moved his face towards them her eyes shot open and she realized what he was about but she didn’t stop even biting her lip and putting bother her hands behind her back it was adorable to see her eagerness. Mark released his grip as he got close taking the opportunity to adjust his now bulging hardon and licking her first nipple he got a thrill when she shuddered from it and when he switched sides she even moaned a little. Mark, feeling confident now, took the opportunity to let his hands wander over her exposed flesh. It was a thrill every moment.

Jane- God that feels good Mark…

Encouraged Mark decided to move down and began to feel her ass through her shorts at this point Jane decided it was her turn and her hands tugged his shirt up over his head and just as he had done began to feel around eventually though she made her way to the bulge the she spotted earlier and began to pet it. It was bigger than she expected and she tried to grab it a little to get the idea that Mark at this stage had backed off from her boobs to look at her as she looked down at what she was doing to him. It was his turn to let out a moan as she touched the tip of his cock through his shorts.

Mark- God sis this feels too good…

She could hear the hurskeyness to his voice that betrayed his lust for her.

Jane- Can I see it?

She moved her hands to his shorts and began to pull them down. Mark was shy about this and thought about resisting but he was thinking about the fairness about it and decided he has more to gain by allowing her. Her eyes filled up with the size of it. I guess when you’re an 18 year old that’s never seen one in real life before it must have seemed enormous at 8inches. She was entranced by it for a few seconds giving Mark the chance to gather some thoughts…

Mark- Uh… Jane… Im loving this but

She looked up and they shared a bit of unsaid communication Jane however wasn’t for stopping and grabbed his cock in her right hand.

Jane- We cant have sex… but there is other stuff we can do.

Mark feeling her hand on his shaft lost all reason and what she done next was mind blowing to the young man. She sank down in from of him and licked the tip of his cock sending shockwaves all through him. Encouraged by a moan she licked some more she kissed the tip and licked it then put it in her mouth peeling back his skin as she did. When Mark opened his eyes the sight of his sister sucking on the tip of his cock almost sent him over.

Mark- wow, thats so good

His hips were eagerly pushing upwards but it was sheer wonderful frustration as her hand on her shaft remained static he released she wasn’t entirely sure what she was doing.

Mark- sis can you stroke it?

Jane looked up, still in her mouth unsure of what he meant which was an amazing sight in itself and Mark gestured with his hand, she got the idea.

She adjusted her position and began to work his penis whilst sucking on his helmet it did not take long and he warned her with his moans but she didn’t try to get out of the way of it and even took more of his cock in her mouth as he exploded in her throat. The best orgasm of the young man’s life she was feeling very pleased with herself.

She waited for him to recover but she wasn’t about to let him rest to long..

Jane- Ok, your turn as she took off her shorthand panties in one go revealing her shaved pussy

Mark for his part recovered at this and was worried about what she was asking, he knew roughly what she was after but… wasn’t sure of the how… he decided honestly was the best policy.

Mark- I will do my best but.. I’m not sure how

Jane- That’s fine i’ll teach you like you helped me.

Mark approached as Jane sat down on a bench they had built and spread her legs slowly he knelt in front of her kissing her on the mouth and all the way down her body until he got to her mound. There he felt her warmth and smelled her sweet scent and began by kissing around her slit.

Jane- That’s good, now if you gently lick down my slit it will open wider

He did as he was told and was rewarded by the bright pink of her insides coming into view.

Jane- God that feels nice, down at the lower part is my entrance please lick that

Mark didn’t hesitate; he loved her sweet taste and stopped only to have a quick look at her hole before licking it and even inserting it in there. She was soaking by this time and moaning. He was surprised when she talked again.

Jane- Thats great here comes the tricky part if you look at the top of the slit you should see a little hood with a round bit under it

Mark- I see it..

Jane- That’s my Clitoris be gentle with….. Ahhh

She was cut off by Mark gently lapping at it.

Jane- Oh god… yeah that’s it… uh try swirling it around with your tongue… yeah like that but don’t focus too much on it… its very sensitive.

He started going from her hole to her clit and she was loving every second of it. He looked up and she had one nipple in between two fingers playing with it as she gushed down below he could feel her building up and her hips began to raise to his mouth.

Jane- Lick my clit Mark … please… oh god

Mark sucked gently on her swollen clit and swirled it around violently with his tongue and when she came he was surprised at the shudder and sheer power of her orgasm. She pushed his head away and he took the hint. He moved up beside her and just held her as she shook. It took a bit but she came back and they just looked into one another’s eyes very pleased with their efforts.

The next day they discussed it and decided they would keep this in the tree house only and tell no one. They were going to do more research next week at the treehouse
