The next day Jill woke up around ten o'clock in the morning. Nobody was home. Jack must have gone out to Sara's. The parents would have left for work early that morning. Jill wanted to spend time looking for apartments. Although her and Jack were in their twenties both were still living at home while they went to the community college here in town. She had a computer of her own, but decided to use Jack's. His was better for net-surfing anyway. She had uploaded about a million and one games onto hers and it slowed everything down. She opened the door to Jack's room dressed only in a t-shirt and panties and felt a little kinky. She tiptoed over his dirty clothes and sat down at his desk. She turned the computer on and opened the browser. She began her apartment search. Having worked at McDonald's for four years now she had saved up a good amount of money. She found three or four that looked pretty good, printed out the pages and was about to leave when she got that kinky feeling back. She wanted to snoop around on his computer and see what dirty stuff might be on it. She began by checking the history - but everything seemed normal there. Then she checked the cookies. Jackpot! There were thousands of sites listed that all sounded dirty. Recently he had been to a site called TeenSex69 about twenty times. She clicked it. Immediately about five pop-ups all came up advertising adult dating sites and sex toys. She closed those and saw the real teensex69 site. It was a giant grid of kids licking, sucking, and drinking each other. She was pretty amused, but simply scrolled down the site taking it all in and almost getting bored. She had been to a few sites like this one. They looked good up front, but really it was the same thing over and over again. If you looked carefully you would see the models repeat, and even the pictures themselves started to appear over and over again. It grew tiring pretty fast.
She opened up the "cookiejar" again and scrolled down to find something more interesting. Most of the porn sites looked the same - then she saw a site called IncenceOfIncest101. Was Jack trying to say something here? She opened the site. Amazingly there were no pop-ups for this one. The front screen had the site's title in large print, and it looked like it was dripping with cum. She clicked the title and it took her to the main forum. It was organized like a blog with separate frames that held a picture in the upper left corner, and then began with a story about the user's incestuous relationship. Upon clicking on the pictures Jill was taken to whole galleries. Some of them only contained the one photo, but others had hundreds of pics that supposedly showed the people's incest acts. You could tell some of them were fakes (probably most of them were) because the actors looked too much like...actors. But upon reading the stories she found that they were very erotic, and seemed to leave out very little detail. She got caught up in the first story and began imagining the characters to be Jack and herself. She started fondling her pussy and made herself wet.
Dan and Danna had been brother and sister for 25 year and that was far too long to go without taking advantage of their special situation. Both had equally strong and sensual bodies that perspired at the mere thought of having sex...
This story was poorly written, but nonetheless it was turning Jill on.
On their 25th birthday they decided to have sex. They confided in each other - it was what both of them were wanting, what both of them had dreamed about for years now. Their sexual fantasies could cum to life - any time they wanted. Dan had his own apartment now. Danna said she would cum over any time he wanted. Dan agreed. They had sex three times that first night. First on the floor, then on the bed, then in the shower. They loved it so much they did it again the next morning in reverse order. After the last sex act they had to take one more shower. They didn't have sex then, but simply admired each other's bodies in the steaming little bathroom.
"Boy this story sucks." Jill said, but she had come into her hands anyways. She was about to close the window when something else caught her eye. An add for "incense of incest", it was only 5.99! She clicked on the picture of a little incense burner. It claimed that it spread an aphrodisiac aroma and that any siblings in range of this powerful odor would become like putty in your hands. They would want you more than ever. (implying they already did). She thought it was stupid and closed the window. Before Jack got home that morning she had gotten back on to the web (on her own computer this time) and placed an order for the stuff - rush delivery.
Later she wondered if she had gone completely insane. This was JACK she was thinking about. Jack, who she was thinking about fucking. It made her mad. She spent the rest of the day in her room confused and mad at herself - but even more so at Jack and Sara.
Jack went to class that next day in a daze. He felt like he and Sara were moving in a new direction. Moving "up to the next level" in their relationship. They had been dating a while now, and they had never really had sex like that before. Before this week he had a kind of obsession, imagining what it would be like. He had seen lots of porn on the internet, but was too scared to ask Sara for anything like that. He figured she would tell him when she was ready. He was glad she did - he wasn't sure how much more he could take. Missionary style had gotten so dull it felt like they were just holding hands. After class he met up with Sara for lunch. He wanted to talk to her about it.
