Chapter 1: The connection

Sara was sleeping in her bed, under her white, fresh sheets, when it all began. It wasn't the first time and it would haven't been the last, that she knew for a fact.

Like always, it's started with the sensation of a little pressure on her lips. She was asleep so she didn't really felt that, but soon she started to stir when she felt a trail of warmth caressing her sides.

Her eyes fluttered open for just a second, just to be sure about what was happening, then she closed them again. She was used to this, even if at the beginning it was so strange and she felt so scared and she thought she was going crazy. How could it be possible? But after some times she simply got used to the feeling. Anyways, there was nothing she could do about it.

Her nipples hardened under a ghost touch. The feeling of soft lips closing around her left nipple was so strong. With the time things became so strong and real. She reached for her other breast with her own hand, caressing and squeezing lightly and teasing herself. Suddenly the feeling of another hand on her chest, fingers pinching her right nipple. Her hand went to cling on the sheets as a soft moan escaped her mouth.

Then she felt the pressure between her legs, she couldn't actually feel the weight of the other body on hers, but the feeling of the thigh pressing on her core, was clear.

"Oh God," Sara said, feeling the wetness increase. Her moans weren't muffled by the pressure on her lips even if the feeling of somebody exploring her mouth, was there.

She started to raise her hips when she felt the rocking back and forth of the other. Her eyes were still closed, focused only on the feeling. She knew she was just slave of the other, there was nothing she could do to get what she wanted and how she wanted. It wasn't about Sara, it was about the other. But she had learned how things were so she knew how to act, how to respond at those stimulations.

The pressure between her legs was replaced with the feeling of fingers drawing small and fast circles around her clit.

"Oh God, Lindsey," she said, and for a moment her eyes opened, just to be closed a second later. It was so strange to say her name, but she got used to that too, in the end, was Lindsey the one that was giving her pleasure, and that had pleasured her for years now.

"Please," she pleaded. But nothing change, Lindsey rhythm didn't changed, even if Sara wanted something more, something a little rough. But that wasn't about her, again. Lindsey was thinking about Tegan, her fingers were working to pleasure Tegan, not Sara. Lindsey was doing what Tegan loved. And that was driving Sara crazy, like always. But that was another thing she got used too. She knew she had to wait, but she was sure that in the end, she would have got her release.

She knew she was incredibly wet, she felt her own cum slip between her legs and on the sheets. She was teasing her breast again, but things were going painfully slow, so she started to slid her hand down. The moment her fingers found the pool between her legs, she felt it.

Two fingers entered her.

"Yeah Linds, like that," Sara said, even if she knew that her approve couldn't matter less. She arched her back, meeting the pace of the fingers that were filling her. Maybe Lindsey was thinking about Tegan, but that didn't mean Sara wasn't enjoying it.

Then the feeling of soft kisses placed on her jaw line, the tongue tracing her pulse point, and then down between her breasts. She knew was it was going to happen and her body arched and shook in anticipation. The feeling of the fingers thrusting into her, never left Sara as she felt a warm tongue joining the dance between her legs, teasing her clit.

"Fuck... oh fu-" the words died in her throat when lips start to embrace her swollen button. A light bite was followed by a soft lick before Lindsey started to suck.

"Oh fuck... I'm... oh fuck... FUCK," Sara yelled in the night as her body tensed for a moment and then went limp as she came. But that didn't mean Lindsey had finished. Lindsey thrust in her again and again, causing Sara to tremble and shake as her body was too sensitive. A few new waves of pleasure hit her before all came to a stop, when Tegan came too.

Sara opened her eyes.

"Fuck, I hate this," she said in the night, at no one in particular as she was alone in the room.

"I hate this," she repeated, reaching between her legs, but even if her words said so, a little smile lightened her face.

She turned on her side. She hoped this was one of that night where it was about just one of them. And it was.

How many years had passed since the first time? Seventeen.

Seventeen years since all began, since that fucking connection was established, since Sara started to feel every sexual encounter her sister had.

Now she could even say with who her sister was fucking. Yeah, now it wasn't much of a mystery, it was always Lindsey. Tegan's girlfriend from four years now. But even before Lindsey, she knew with who her sister was.

It was so strange to think that basically, Sara was having a relationship with Lindsey too. Like a sexual relationship without all the other problem that came with a real relationship.

Sara had learned every sexual habit in Lindsey and Tegan relationship. She knew what Tegan liked because Lindsey was always ready to give it to her. Sara knew every single thing her sister loved. It was so weird to think about that. She wasn't supposed to know what her sister liked under the sheets. But part of her was happy to knew, a little part that Sara had buried inside of her a long time ago, around the time when all started. She had buried those thoughts and feeling so deep inside that she didn't even know they existed anymore. The only times she felt different, she felt like those feelings were surfacing again, was when it wasn't Lindsey the one fucking Tegan, but when was Tegan herself.

It's wasn't something that happened very often, just when Lindsey left due to work for a long period. But every time Tegan masturbated, Sara felt something different, and special. And she hated that even more than the feeling of Lindsey fucking her. Lindsey didn't never mean a thing to her, or better, they were friends, but Tegan... Tegan was her twin sister, and even if she had buried those feelings so deep into her, she loved her so much, and she still loved her. And every time Tegan get herself off... for Sara was basically as her sister was fucking her, and that was so heavy in her mind and in her heart. Because every time that happened, she remembered that those feelings existed, even if she was trying to deny them.

She didn't know why, she didn't know how...

But she knew exactly WHEN it all started.
