Night was falling, the crimson glow of a flaming sunset shining through the window.
Kristen was too distracted though to even notice how the sky seemed to be spectacularly ablaze. She was totally focused on the open spiral notebook that lay in front of her, it's blank and empty pages seeming to cruelly mock her. Lying sprawled on her belly atop her bed, propped up on her elbows and with her chin resting on her clasped hands, she couldn't help but marvel over how evil this seemingly innocent book really was.
The pile of crumpled up wads of paper on the carpet next to her had been growing steadily all afternoon and was a testament to just how much trouble that notebook had been giving her.
Still, the nineteen year old had resolved to do this come hell or high water and was determined not to stop until she'd finally defeated her new nemesis.
So focused was she that the soft sound of footsteps out in the hallway was not quite enough to make her look up. No, it was not until she heard them pause that she was tempted into looking back over her shoulder at the open door to her bedroom to see who might be out there. It proved to be her sister and a smirk put in an appearance when she saw how intently the younger girl was studying her butt.
"Hey, Ruthie," she greeted. "Where have you been? I haven't seen you since supper."
"Hmm?" Ruth had been so interested in the other girl's seat that she almost didn't catch what had been said. "Oh, dad gave me a little . . . dessert."
Kristen shook her head with a sigh.
It had been almost a month now since that wild weekend where she and her family first started practicing incest and it didn't seem like it was going to stop anytime soon. If anything, they seemed to be getting crazier and crazier about each other by the moment! Considering some of the things they were getting up to nowadays, crazy was a pretty good word for it, too.
"Say, have you heard? Dad's gonna take mom out for a romantic dinner this Friday. Just the two of them! He said it'll be their first real date night in years!"
Kristen smiled. "I bet they have a good time. They might not even come home until the next day."
"I have a feeling that's what mom is planning." Ruth had a wicked smile on her face, reaching out to play with her big sister's hair. "I wonder what we'll find to do when they leave us all alone for a few hours here at the house? Do you think we'll be able to find some way to keep ourselves occupied?"
The other girl chuckled softly. "Don't you ever think about anything but sex anymore?"
"Nope." Ruth pulled her sister's hair back, leaning in to plant tender little kisses on her neck.
"Good." The grin on Kristen's face was every bit as evil as the one on her sister's.
Kristen's nose twitched, catching the scent of her father's cologne on the eighteen year old. Where once he had only worn that stuff on special occasions, he was now wearing it a lot more often than ever before, clearly hoping it would make him smell more manly and irresistible to his women.
Bent forward as she was, Ruth took advantage of the opportunity to have a look at the notebook lying on the bed, surprised to see the pages blank. "So, what have you been doing up here? Still working on your homework?"
"No, that's all done. Actually, I've been trying to write a story."
That surprised Ruth. "A story?! What for?"
"Well, I got on the computer the other day and did a search for incest. I guess I was just wondering if there were any other families out there where sister's were having sex with each other, or moms and daughters, or fathers and daughters, or whatever. Nine tenths of what I found was just really crappy porn of course, but eventually I stumbled onto this place called Literotica. I was looking for real-life experiences and all this place had were fictional sex stories and so I almost dismissed it and moved on, but then I decided to read a few of the stories. There was plenty of weirdness in those things and some of them really stank, but I was pleasantly surprised to discover that there were a lot of really good ones in there, too."
"So, you just suddenly decided to write a story of your own?"
"And why not? I'm as smart and creative as any one else." There was a defensive tone to Kristen's voice, Ruth noticed.
Ruth sat back up. "Okay, okay. I didn't say there was anything wrong with it. So how's it going?"
Kristen slumped a little, wordlessly jerking her thumb towards the pile of paper wads beside the bed.
"It's a little harder than you thought it would be, huh?"
The defensiveness was back in an instant. "I can do this, Ruth. I can write a stupid little story."
"Would you relax?! I never said you couldn't write a story, Kris. Like anything else though, I'm sure it takes a little practice to get good at it."
Kristen nodded. "Sorry."
"So," Ruth ventured after a moment, "Have you figured out what you want to have happen in your story?"
"Well, you remember that I told you some of the stories there were a bit weird? I thought I might stand out from the crowd more if I did a story about something a little out of the ordinary."
"Yeah?"
"So, here's what I came up with. It's about this woman who is divorced or widowed - I haven't decided which it should be yet. There's hardly any money coming in and so she lives in this little tiny apartment all alone except for her innocent teenaged daughter. Normally, she and her daughter have a perfectly ordinary relationship, but everything changes at night. The daughter sleepwalks, you see, and becomes a raging nymphomaniac. And how does she satisfy her overpowering, yet unconscious need to get laid? By slipping into her own mother's bed, of course. Mom is a little weirded out by the fact that her sleeping daughter is ravishing her once or twice a week of course, but it's the best sex she's ever had and so she isn't doing anything to try and stop it."
Kristen waited for her sister's reaction to her story idea, but the look on the girl's face told her everything she needed to know. "You don't like it."
