****Danny****
Danny sighed and pushed his keyboard away in disgust, looking at yet another half page of words, the beginnings of an erotic story. He'd started at least a dozen stories in the past couple of weeks, and had never gotten more than a couple of paragraphs. "What is wrong with me?" he wondered silently to himself as he highlighted the text and erased it.
He couldn't understand it; he'd never had trouble writing before. An idea would come to him, inspiration of some kind and he'd be off, typing furiously at his keyboard trying to keep up with his imagination. Hours later when he finally finished he'd be breathing hard and his cock would be aching in need from all the times it had swollen painfully in his jeans as he wrote. Then he'd post it on his blog and hope for a good response from some of his followers, which he usually got.
But lately the inspiration just wasn't coming. He tried to force the stories out but just felt blocked. None of his fantasies were inspiring him anymore and even suggestions from some of his fans didn't seem to strike a chord in him. He growled out loud in frustration and looked around his room.
It was a typical 19 year old kid's room with posters of girls, cars, sports, and bands covering the walls. The bookcase was full of novels by his favorite authors, except the bottom row which held his favorite movies. Turning away from the computer he pressed play on his stereo and collapsed onto his back on the bed. A mix of oldies, rock, country, and R&B filled the room as he lay there and tried to make his mind as empty as the now bare document still on his computer screen.
****Karen****
Karen heard her step-brother's growl of frustration, followed minutes later by his music coming through the wall that separated their bedrooms. "Not again!" she thought to herself as she reached for her phone. She knew what that growl meant, Danny still couldn't write. Opening up his blog on her phone she confirmed her suspicions, no new story waited for her, waiting to flame the embers smoldering inside her, the lust and desire that had been building for years.
She wished she could go in and help him; encourage him or inspire him to get back to writing. But that would mean admitting that she knew what he did in his spare time; Admitting that she had found his blog and had become obsessed with his erotic literature months ago. And it would mean that she had continued to read his stories after realizing that her favorite sex author did his writing just down the hall from where she read them.
"He'd know." she told herself again. He'd know of her feelings for him, how she longed for him to take her like he took those girls in his stories; ached to be tied up and claimed by the man that she spent every night lusting after. She still didn't know when she had begun to feel this way for him he'd always just been her big brother Danny, even if he was only her step-brother.
A few hours later Danny poked his head in to tell her that he was going out and asked if she needed anything. "Nope," she said and gave him a smile before he left. She could tell that he was still feeling frustrated and hoped that he'd snap out of it soon. It had been almost two weeks since she had been able to cum and she was starting to get desperate. Hours of rubbing her tight little eighteen year old pussy just wasn't enough, she needed Danny's words, his stories, his fantasies of Domination and submission, lingerie and bondage, spanking and biting.
Karen bit back a scream of frustration as she felt her pussy pulsing. She had been so sure he'd get a new story posted tonight and was looking forward to a good hard cum. "Fuck I need it." she told herself as her hand wandered down over her cotton sweat pants. After a soft rub on her sensitive clit she forced her hand away and climbed out of bed. She knew that teasing herself wouldn't do any good tonight.
"Maybe a warm bath will help me relax," she thought and headed for the bathroom. Just as she was about to pass Danny's room she saw that his normally locked door was open a crack, and she could see the glow from his computer monitor. "Maybe he has a half finished story on his computer," she thought as her hand reached to push the door open further. Biting her lip she took a step inside. She didn't want to betray Danny's trust, but just the thought of reading a new story made her pussy drip even more.
She sat down at the computer and released the breath she hadn't realized she'd been holding. A blank document filled the screen and she frowned in disappointment. "Maybe he saved something," she said to herself and reached for his mouse. Finding a folder marked Stories she opened it, but all she found were the stories he'd already posted. She was just about to give up when she found another folder marked SBSS. Curious she opened the folder and found inside about 25 document files. Her eyes grew wide as she read the titles, every single one included the words step-sister as part of the title and the last one read Claiming my sexy slutty step-sister
Realizing again that she wasn't breathing she opened this last one and began to read. Within minutes her hand was buried in her sweats rubbing her dripping slit and her breathing had returned, rough and ragged as she read as fast as she could. She read of a step brother lusting after his slutty little step sister, jacking off to thoughts of her every night and finally losing control and capturing her in the shower, taking her like the naughty little slut she was and claiming her forever. She read on and on, realizing that he was writing about her, wanting her, lusting after her! Sloshing sounds filled the room as she furiously pounded her poor little pussy with her fingers, trying to get deeper, more, harder. The pressure was building; her vision was going blurry making it hard to read about his thick cock pulling out of her pussy, throbbing and pulsing before exploding with ropes of cum shooting over her dripping body...
"FUUUUCKKK," she wailed as her back arched in Danny's chair and her orgasm washed over her with the force of a tidal wave. Her breath was lost for the third time, stolen from her by the waves of pleasure that wracked her curvy body. It seemed like hours of bliss went by before she recovered and straightened in the chair.
Grinning in relief and excitement she reached for the keyboard, knowing that despite his hidden Dom side, Danny would never take her the way she craved without a little prompting.
****Danny****
It was late by the time Danny got home that night, late enough that all the lights were out and he assumed that everyone was asleep. As he parked his car he looked at the clock and gratefully reminded himself that he didn't have to work in the morning. "Dad and Renee will be gone, and maybe Karen will be out and I can have the house to myself for a change," he thought as he walked up the drive. "Maybe I'll finally write something besides dirty stories about Karen."
Danny had been blocked for weeks, unable to write his stories, unable to find any inspiration that didn't involve his sexy stepsister. He'd been able to write stories about her, but couldn't share those online like he did his other smut. He was too embarrassed by his attraction to her. He was supposed to protect her, not spend all day undressing her in his mind.
Danny paused as he passed her closed door, thinking of the gorgeous girl on the other side, probably wearing a tank and panties to bed like usual, her soft pale skin exposed... "STOP IT!" he shouted to himself and forced himself to walk towards his room.
Seeing the open door he paused, wondering how he had forgotten to close it. The glow from his monitor still filtered through the doorway which puzzled him as well. It should have gone to sleep by now. Danny walked into his room and flipped on the light. Instantly he knew that someone had been in his room. Some of his things had been moved around and there was an unusual smell that he couldn't quite place. Looking around he focused on his desk, and that's when he realized that someone had not only been in his room, but one his computer! The keyboard was tilted at an angle and his chair had been pushed back.
"Oh fuck," he breathed, realizing that he hadn't bothered to lock the computer or hide the stories about Karen. He didn't care if anyone saw the other stories, but if Dad or Renee found one of his incestuous fantasies... He didn't want to think about it. Pulling his char back up to the desk he sat down.
Reaching out he moved the mouse and the screen saver disappeared. Sure enough, the first thing he saw was the open folder with all of his step-brother, step-sister fantasy stories. Shame and anger filled him, anger at being stupid enough to get caught, and shame that he had acted on his incest driven desires.
Danny moved the cursor up to close the window, as if doing so could hide the damning evidence that had already been seen. "Seen by who though?" he wondered. Suddenly his eye froze, caught by the title of his latest story. He remembered naming it, remembered thinking that the title was silly and not exactly professional, but it didn't matter because no one would see it. He definitely did not remember adding Karen's name to it though. He'd never put her name in his stories, pretending that he was just writing about some random step siblings. But there it was. Karen: my sexy, slutty, step-sister.
Sitting back in the chair he stared at the title, wondering what it meant and who had changed it. Suddenly he felt something cold on his ass.
Reaching down he realized that the fabric of his desk chair was extremely damp. It had been seeping through his jeans the whole time he'd been sitting there. Finally it clicked what he had smelled when he had walked in; his chair was covered in cum!
"Karen," he whispered, realizing who had been in his room. Karen had sat at his desk and found his stories, and apparently she had made herself cum while reading them. He couldn't believe it. He was mortified that Karen now knew that he lusted after her, but why did she cum? Why wasn't she disgusted? Why did she change the title? He couldn't understand it. Movement out of the corner of his eye drew his attention away from the computer. His step-sister stood in his doorway watching him.
"Fuck, Karen, It's not what you think," he began hurriedly, trying to explain, somehow make her believe that he wasn't writing about her, it was just some random fantasy, anything.
"It's ok Danny," she said softly, her voice instantly causing Danny to fall silent. "I know you were writing about me, and I loved reading those stories."
"What?" Danny asked incredulously, "but they're so...." He couldn't believe that sweet little Karen would have enjoyed reading his kind of smut.
