Mike and Layla, both 19 years old, always had a really strong relationship, they were like soulmates in a way.
The harmony the pair produced made it feel like they were more than brother and sister in a way, they just fit together perfectly like two puzzle pieces.
Layla was a brunette with long hair, brown eyes and a pretty slim body, almost athletic in a way. That day she was wearing a tight dark nightgown that really showed her curves. A body quite attractive despite being covered by the fabric.
Mike on the other hand, had short dark hair, with the average teenager haircut, green eyes, and a rather athletic build from his childhood training as a football player. The girls always found him handsome.
He was just wearing a pair of pajama bottoms and an adjusted white t-shirt.
That night, their parents had arranged the usual movie night where they would be watching whatever movie was set to play at the time.
They would all sit together and watch whatever they played that day, sometimes it would be a complete success and the movie would stay on the screen all night long, or it would be a failure and they just went to bed before it finished, it depended.
A while after dinner, their parents called them as the movie would begin in around ten minutes or so. The siblings took their time to come downstairs to the room.
The lights were dimmed down and pretty much the only thing visible was the light coming from the television.
Once they entered the living room, they heard their parents voice:
"It's about to start. Come get ready!"
Layla sat together with Mike on the same couch, located beside the two seats their parents sat on, their couch was located a little behind their parents seat.
They were both silent, staring at the TV as the movie was about to begin.
The music started and they laid on the couch while covering themselves with the blanket.
The siblings locked eyes for less than a second and smiled lightly before returning their focus to the TV.
Half an hour later, they had been watching the movie in silence, cramped together under the wide piece of cloth covering them.
Mike felt that the temperature was rising under the cloth and began to sweat slightly, Layla hadn't complained all this time so Mike just ignored it and continued watching the movie.
A few minutes later the movie presented an erotic sex scene, one that movies always seemed include, and that made things awkward for the people watching with their families, just like it was happening to Mike and Layla right now.
Mike was trying hard to concentrate, but the sexual tension was becoming too much to bear.
He looked sideways, slightly meeting Layla's view and tried to keep his cool as he could see their faces heating up.
If Mike's temperature had been rising in the previous minutes, it was now climbing up like a furnace beyond boiling point.
His body grew warm and sweaty from being under the blanket and he didn't even know what caused his heart rate to speed up.
Mike couldn't believe he had gotten into this situation next to her own sister.
He wondered if she could feel his heat. The sexual tension was rising considerably, and the sex scene just continued playing.
The scene seemed to last forever, Mike tried really hard not to get aroused as an erection grew, hoping his sister wouldn't realize.
But the fact that he couldn't keep his mind off the situation was making it harder, and he felt the need to pull his sister closer to him to feel her heat.
He didn't understand why he felt like this, why his brain seemed to be telling him that it would be better if she got as close as possible to his body.
But in one swift motion, Mike adjusted his position and rested closer to her. He immediately noticed how warm she was, just like him.
He felt her tense, but then relaxed quickly. She placed her hand on his knee, gripping it lightly, almost as if in comfort.
He was surprised by the contact, relieved from the current state he was in.
Layla locked eyes with him, her eyes had an indescribable look of lust and passion, it shocked Mike.
Taken by the feeling, both siblings approached slowly until their lips touched slightly, closing themselves in a slow kiss that lasted less than a second.
Afterwards, Layla turned around and stared at the TV with a numb face, wondering what just happened, Mike had the same expression. He wanted to ask her if it was wrong, but decided against it.
His heart was racing and he was pretty sure his sister felt the same way.
After what felt like an eternity the erotic scene had ended and the movie resumed normally with the plot, despite the change, the siblings couldn't focus on the movie any longer.
The sexual tension in that room grew to unimaginable levels.
Mike had given up on resisting any longer, his arms were wrapped tightly around his sister's waist. The sensation was so overwhelming that her body reacted without warning, leaning back towards him, Layla's butt now rested on her brother's pants, pressing into him.
His member grew hard and heavy inside his shorts, rubbing against the fabric, it felt weird to be touching his sister's ass through the piece of clothing, but it felt so good that his mind pushed those thoughts aside.
He could hear her shallow breaths and the intoxicating scent of her lust and sexual tension, corrupting the young man's senses.
It wasn't long before Mike was feeling every inch of his sister's body, embracing her in slight movements under the blanket, while their completely oblivious parents kept on watching the movie.
Layla turned smoothly meeting her brother's eyes. Filled with lust.
"More", she said with a voice that mixed the sweetest tone with the softest seduction.
Mike responded instantly, kissing her, taking full control of the kiss. It felt natural.
Mike didn't want it any other way. He wanted his sister in any position.
