*******

Sian and her twin sister; just two siblings of five, Sian always found that getting noticed by her parents was difficult. Trying to get some time were she wouldn't get interrupted and could just have some peaceful time to herself would be even harder. She hated it. With her annoying little sister who had just turned fourteen constantly bugging her all the time, her older sister just existing to make her life a living hell and she didn't even want to think of her older brother... the arsehole.

Sian always wondered what it would be like just to be living on her own. Ok maybe that wasn't quite true, her twin is her best friend, so living with her is what she always wanted.

It is the beginning of the summer holidays and Sian had been looking forward to no school. It was always the one time of the year when it was almost like she lived on her own with her twin. Everyone else had work or summer camp as in the case of her younger sister and this year is no exception.

"Yeah this is the life!" Lilly her twin said, mimicking Sian's own thoughts exactly. They were using their first day of the summer holidays well, relaxing out in their back garden on the sun loungers that faced the back of the house. Between them and the house a nice, clean pool.

Sian couldn't help but smile, the sun is warm and they would get a nice tan in no time. Sian opened her eyes to look at her twin when she spoke and couldn't help but lose her train of thought about summer. They are both eighteen and are alike in countless ways apart from their appearance. In fact they could easily be mistaken for being unrelated. They're fraternal twins, as in they do not look identical. Sian always did wonder how they look as different as they were, even for fraternal twins they should have a lot more likeness with each other than they do. Only their noses are similar. Were Sian has beach blonde hair, Lilly has luscious dark brown, Sian has sea blue eyes and Lilly has mesmerizing hazel eyes.

Their bodies are alike in height and size however Sian always thought her breasts were smaller. Sian couldn't stop her eyes from wondering over her twin as Lilly's eyes were closed. Lilly had a nicely proportionate body, they were both around 5'7 however Sian always like how her twins body was slim but not overly toned and had a modest hour glass figure. If Sian had to describe the perfect female body she would simply get a picture of Lilly's. Her travelling eyes drew an outline of Lilly's breasts in all their B - C cup glory contained in her white bikini top. Sian could even see the bumps of her nipples which were surrounded by a darker silhouette of her areola. She watches as a bead of sweat trickles from between Lilly's breasts to her belly button, following the slight indentation between her ab muscles. Her eyes kept traveling down her navel to the tip of Lilly's matching white bikini bottoms...

Sian once again caught off-guard and blushes at how she always had some kind of attraction towards her twin sister and tears her eyes away, closing them as she settles her head back down to laying on her sun lounger, sunning her front. She just couldn't help it; she always knew that guys didn't do it for her, and that the idea of being a lesbian was alluring with the naughty taboo, or so she thought of it as; but she lately noticed more frequently how she was noticing her own twin more and more as a woman and not a sister. "It's wrong, but, but she is so, sooo..." She couldn't finish the thought. Sian loved her twin as a sister but these new feelings were too powerful to ignore and were always confusing. She was so lost in her own feelings that she fell asleep in the warm sun at some point.

Sian started dreaming about her twin sister! In particularly, her twin sister rubbing her hands all over Sian's naked body! Sian could feel herself getting wet from the sensation of it, her nipples hardening and her breath coming faster. That's when she realised that Lilly was rubbing her and that it was real! However it was only her legs and Sian still had her two piece bikini on.

Opening her eyes Sian look down in alert for a second to see Lilly rubbing in sun lotion on her legs as she squatted on her haunches next to Sian's sun lounger.

"Aheh! It's just me, you are starting to get a little red so I thought I would get some lotion on you, sorry to wake you." Lilly smiled warmly after a little giggle at Sian's reaction, reminding Sian of an anime character the way Lilly smiled with her eyes closed for a second.

Relaxing Sian said, "That's alright, feels nice."

"I am glad you like it; want me to do your upper body as well when I've done your legs?" Still smiling Lilly asked as she returned her attention back to Sian's legs. Gently but firmly enough to make sure the lotion was rubbed in properly and spread evenly, Lilly had a very cute concentration look as she continued to rub the lotion in. Sian almost missed what she said and it was a moment or two before she could trust her voice not to betray a sudden giddiness she was feeling. She was almost lost to Lilly's touches for a moment.

"If you like, thank you" Sian said.

Sian continued to watch as Lilly rubbed the lotion in to her right lower leg and right foot. Lilly taking her time would rub the lotion in her hands briefly before spreading her fingers wide to rub up and down Sian's lower leg and finished with a little short foot massage. She then repeated the process on Sian's left lower leg and left foot, every touch sending tingles and shivers up through Sian's body which she made sure not to show in any movement at all.

Sian's Breath caught a little when Lilly moved her hands to Sian's lower thighs, only now she was doing both legs simultaneously, with one hand on each. Sian hadn't noticed that Lilly had repositioned herself so that she had gotten partially on the sun lounger with her left foot on the floor and sitting on her right knee which was now between Sian's calves. Lilly was almost straddling Sian's right calf. Sian had closed her eyes as Lilly seemingly inched her touches up Sian's thighs slower than she was moving her hands before. She was doing all she could not to let out a moan because of how good it felt. Despite that she couldn't help but let out an audible rush of air as Lilly's hands rubbed the inside of her thighs only a few inches away from her bikini panties for a second before they moved around to the outside out her legs.

All too soon, for Sian; Lilly's hands left her legs altogether, however before she could find the strength to open her eyes to look to see what happened to Lilly, Sian felt her soft hands once again on her bare skin but on her stomach this time. Both hands, one either side of her belly button, Lilly's hands started to roam in small circles down to just touching the top of Sian's bikini bottoms and then only her fingers and very top of her palms could be felt as she traced around the top of the bikini bottoms. Usually Sian would writhe and wiggle around because of her ticklish sides but as Lilly's hands traced up her sides she could only feel the soft hands on her skin and the sensual feelings they created. Lilly's fingertips met the string straps of Sian's bikini top and traced around the very bottom of her breasts until they met in the middle touching the connecting strap between each of Sian's bikini cups.

Her hands left Sian's skin again but quickly returned to each of Sian's wrists. Simultaneously, Lilly's hands traced every contour and fine muscle on Sian's slim arms up and around her shoulders to her collar bone. Sian's bikini had no shoulder straps, just the string tied around her to her back holding it to her frame. Lilly's hands seamlessly traced around above Sian's breasts, gently rubbing the lotion into the upper parts of her breasts which showed above her bikini cups. The pressure causing the bikini cups to slide a bit lower and every Millimetre of skin that was exposed was rubbed with Lilly's fingers. Lilly's palms were almost cupping Sian's tits. Lilly rubbed the lotion up and finally around Sian's neck and briefly around Sian's facial features.

Once again all too soon, for Sian; her body suddenly felt cold in the warm sun of the summer day as Lilly's wonderful touch left completely. She kept her eyes closed as she bathed in the sensations she had felt thanks to Lilly's hands. Her skin kept tingling, her breath coming quick and irregularly. Sian couldn't help but feel incredibly turned on. She was dripping wet and her palms were sweating.

"Do you want me to do your back too?"

Sian's eyes snapped open; she had almost forgotten Lilly was still there.

"Uhh, umm, No!" She almost shouted it at her twin. "I think I have had enough of the sun today, thanks, err, I'm going to get a shower." She wasn't sure if all she said was understandable but before Lilly could say anything, Sian was already heading into the house and out of sight.

Once up in her bedroom, which she shared with Lilly, Sian quickly locked the door and tore off her bikini to furiously masturbate on Lilly's bed.

Down stairs Lilly was all smiles, she had been lusting over her twin for a while now and couldn't resist rubbing her hands all over Sian as she lay out in the garden all sweating and teasing. At least that is how she felt, she had thought "the hell with it, I need to feel that toned body, to hell with the consequences!" Sian's body was athletically toned, but not too much, just how Lilly loved it. She had spent a couple of minutes just staring at her sleeping twin on the sun bed, using the time to build up the courage to go through with her plan to use the lotion as an excuse just to feel her. Sian, with her perfect B - C cup breasts and beautiful face framed with her blonde hair. Lilly could tell she was having an effect on Sian from the very beginning of the impromptu massage, she could see how wet she was from the darkening patch of Sian's dark blue bikini bottoms between her legs. Lilly could even smell her arousal when she leant over her twin, which just encouraged her even more.

Despite the effect she knew she was having on her twin, Lilly knew she couldn't rush Sian. She didn't want to ruin their relationship as it was already so she must be patient. She loved her twin as more than just a sister and wanted more than anything for her to know it. Even if it meant Sian didn't see her the same way. But if there was a chance that Sian felt something, anything for her, then Lilly planned to take it.

After multiple orgasms and a shower which had included another, Sian was relaxing watching TV in their bedroom when Lilly finally came in from sunbathing downstairs. Sian was contemplating what had come over her, why she had needed to release some sexual tension by fantasizing over her own twin sister!? The house was quiet, being the only ones in for most of the day Sian heard Lilly from all the way down stairs to the kitchen.

"Want a drink!?"

"Yeah! Coke Please!" Sian responded, although she had no idea why she asked for a coke, all Sian and Lilly drank was Coca-Cola. Lilly would have known to grab a coke anyway.

"Ahhh they are lovely and cold" Lilly was saying as she came in their bedroom looking slightly red from her sunbathing.

Their bedroom is quite big, but then again it had to be, they are the twins of their family and the house wasn't big enough for all the siblings to have their own bedrooms so the twins had always shared. The door is in one corner of their rectangular bedroom; to the immediate right a set of Chester draws with their TV on top which is in the centre of their bedroom against the wall. Directly opposite against the opposite wall is a bed side Chester draw which has an alarm clock and a lamp on top. On each side of the centre of their bedroom are the beds; Sian's bed directly opposite the door and Lilly's bed on the other side of the centre, they both only having single beds. Their bedroom is easily big enough to be able to walk around all three sides of their beds with their head boards being up against the furthest wall from the door and TV. Their only window is on the wall furthest from Sian's bed which overlooks their garden and finally opposite Lilly's bed is their pride and joy, mess of a walk in closet/wardrobe.

Sian was laying reverse on her bed on her front with her head towards the TV with her legs curled up and feet in the air when Lilly handed her the coke can on her way to her own bed.

"You should have a shower hun, before everyone comes home later" Sian said.

"After this" Lilly indicated her coke, "Is there anything good on TV?"

"Too early for anything good. Do you want to do something?" Sian asked, she could never stand to watch TV, always preferring to play a game or go out shopping or anything really.

It was the anything that always leads to Lilly asking sceptically "like what?"

"Shopping!" Sian decided at random.

*******

It was getting towards dinnertime when Sian and Lilly came back from their sudden shopping trip into town, however they didn't buy anything except a late lunch, having left to go into town at about one in the afternoon.

All the family was home for the evening with the exception of their younger sister who was at summer camp and their older brother who had moved out. Their younger sister is fourteen and only just had her birthday recently, Sian and Lilly being both eighteen, their older sister being twenty-two and their older brother being twenty-six.

The twins coming through the front door were greeted by an almighty row coming from the living room which is on the other side of their kitchen. It was easy to hear the shouting since their kitchen had no doors other than to the wash room. Coming in the front door the stairs leading upstairs are on the left and to the right, a big open archway in the wall lead into the kitchen. Running in an L shape around the right wall to the furthest wall of the kitchen were the counters, sink, cooker and refrigerator. A largish dining table with chairs in the centre and behind that on the left wall of the rectangular kitchen another archway lead into the living room. The door to the washroom is tucked away to the immediate left as you enter the kitchen coming from the front door and stairs.

"I HAVE HAD ENOUGH OF THIS SHIT!"

"WHAT SHIT!? AND WILL YOU STOP SHOUTING!"

The shouting quickly became white noise to Sian as she led the way inside. The shouting was coming from her mother and older sister. Their Dad was just casually carrying on making dinner in the kitchen as though he was deaf. He didn't even notice the twins stealthily make their way upstairs.

"They are at it again." Lilly simply said as they entered their bedroom. The shouting was still quite audible even from their bedroom until Sian closed the door behind her. Their room was surprisingly soundproof.

"They are always at it" Sian said with a yawn.

Lilly got up then turning towards the door, she said over her shoulder, "Just going to ask Dad something" and with that she left, closing the door behind her.

Sian just flaked out on her bed, her shoulder blade length hair splaying all over her pillow around her head. Closing her eyes she remembered that morning on the sun lounger, why had it felt so good? Yeah she liked a massage as much as the next person but it had felt like so much more than that. It was... sexual. Sian kept repeating several questions over and over in her head. Did Lilly know what she was doing? Did she know how turned on I was? What does this all mean?

So consumed in her thoughts she felt like she must have drifted off to sleep. Next thing Sian knew Lilly was shaking her gently awake. Behind Lilly on her bed was two trays, both with the dinner dad had cooked on plates.

"Hey sleepy, I asked Dad if we could have our dinner up here and he said yes. Do you still want it?" Lilly was asking.

"Hmm yes please. Thank you sis." Sian yawned out as she sat up and crossed her legs while rubbing her eyes awake.

"There you go." Lilly handed Sian one of the trays, which Sian carefully placed on her crossed legs. It was essentially a roast dinner but with a lot of gravy.

Lilly likewise sat on her bed crossing her legs just like Sian had done with the dinner on her lap. They sat eating their dinner while watching their TV quietly for a while.

Lilly was wondering how to broach a topic so wasn't paying attention to the TV. It wasn't until Sian had to say her name for the third time that Lilly finally surfaced from her thoughts.

"Sister to Lilly!"

"Hmm what?" A barely registering Lilly replied.

"What's with the lost look?" Sian was gazing at her curiously.

"Oh never mind, was just thinking, what's up?" Lilly said.

"Well I was trying to ask you, are you finished with your dinner?" Sian's smirk at her cute sister couldn't be hidden. "Do you want me to take it down for you?"

"Oh yes please." Lilly's smile was very cute how she closed her eyes when she did.

Sian hadn't been gone five seconds before Lilly was lost in her thoughts again. All she could think about was how to kiss her own twin sister and talk to her about her feelings.

It was getting late as the twins relaxed in their bedroom. They had barely seen or talked to anyone else in the family today and Sian was as content as she could be. Having had enough of TV, which they rarely watched anyway, they had turned it off in preference for some music. Lilly was busy on her laptop while Sian was laying on her back playing with her phone with her head on her pillows.

They had a very large playlist of music but they both had only a few favourites, which they shared of course. So when 'Give me everything (tonight)' by Pitbull started playing, which is one of Lilly's top favourites, she couldn't help but start moving to the music. Even lying on her front facing towards the end of her bed with her legs curled up into the air she was still able to wiggle her hips and dance her feet in the air in such a way that Sian's vision was torn from her phone to her sister instantly.

The fact that they hadn't changed for bed yet meant that Lilly was still wearing the cotton peach pink short skirt that she'd worn to town. When standing it had barely come to within a couple of inches of her knees but now, with her lower legs dancing up in the air, the skirt had flipped back showing everything. With the angle Sian had she could see Lilly's long, softly toned, tanned legs leading up to her darker pink French lace panties. Sian was practically drooling at the sight; she could even see the darker skin of her twin sister's vulva through the panties! Lilly's panties were drawn tight pulling her vulva apart giving them a distinctly darker shade from the wetness of her pussy!

Her own body was responding to the sight too, Sian was practically a burst dam with how quickly she was dripping wet between her thankfully tight jean covered thighs. Sian couldn't stop staring and absentmindedly licked her lips. She had no idea that Lilly had tilted her head down so she could see, through her dangling hair, the effect she was having on Sian. Even with the upside down view Lilly had, it was clear how attractive she was to Sian. That thought made Lilly even wetter and the fact that Sian could see it as well made it all so much more of a turn on for Lilly.

It got to the point that Lilly could take no more and suddenly dropped her legs back down to her bed, turned onto her side and looked Sian squarely in the face.

Sian knew she had been caught looking, no, staring at her twin. She was immediately panicked with fear that her sister would think her a pervert or a freak or something. Sian couldn't think what to say or do and felt like bursting into tears. She had ruined their friendship in one moment! There was no way Lilly would even feel comfortable being around her now!
