Thread: A Sister's Mistake (Textual_Intercourse x Sheena-Tiger)

Valerie was quite happy. Today was Friday and that did mean for the 18 year old girl, that she would spend 2 nights at her sisters place. Since some time now, she was working for her sister, even though it was not always only a fun experience, but her sister Katie never had been unreasonable and only helped her to grow while learning from her mistakes. Despite her making a pouting face and attempting to look at her older sister with puppy eyes, Katie always had been adamant and over the long run, Valerie felt it had helped her every time. Yes, she earned a few bucks from working for her sister, but the main reason really was to gain practical experience for future life, giving her an edge out there. Aside from working for her sister, which came with some boons, despite Katie attempting to be a real boss, Valerie finally felt close to her big sister once more. For years she had looked up to her sister, their bond had been something special and they had many fun times. Katie had always protected her, making Valerie look up to her and often cuddle with Katie when they watched movies. Some time ago, Katie left her life nearly completely and Valerie always had wondered if she had done something wrong and missed the strong arms of the older sibling and how she smelled or that firm voice when she stepped between her and some bully. Within the last years though, something else had been growing within Valerie as well, something disturbing. When she thought about her sister there was still the warmth she knew, but another kind of warmth was adding to it. Since a few months, she found herself exploring even more, mostly herself, while thinking about her sister and her hidden secret. Of course, she knew what Katie was hiding and why, but it only added to some dark fantasies she enjoyed late at night, with both hands below the blanket and hoping her parents would not hear her voice. During the day, Valerie hid these fantasies and emotions well, from everybody. She feared it would push another thing between Katie and her, now that they had found together again and pushing Katie away was the last thing on her list. More important was, spending time with her sister. After they had finished work, they could sit together, Valerie could lean into her sis, and they could enjoy a movie or just chat a bit. Everything else would only destroy this peace, Valerie was sure about that. Being the sister came with the boon of her own key to the building and she used it, only on the days she was expected of course. Not seeing or hearing her older sister Valerie shrugged, it would not be the first time Katie would be home after her even though it was seldom. She left her luggage in her designated bedroom and settled down in front of the computer which she found running. Her plan was to only look up some of her own stuff but there was a browser open and being young meant for Valerie, that she was quite curious. She opened first the pictures, looking at them. Finding her sister having a picture of her was not disturbing, she owned a few of Katie as well. How she used them was nothing she would discuss of course. It only took her a short time to read the mail, knowing she should not ever do that but it simply happened. From there it only took her a few seconds to connect the picture of the other girl with the mail and that one with the one of herself. Valerie gasped while drinking in the picture of that other girl. Her hairstyle was a bit different and the clothes were of leather, Valerie assumed, but was not sure. A few other words flew around in her mind right when she heard a door. Panicking she opened another browser and logged into her on mail account, hoping she would not be to pale or red when Katie would find her. Thinking fast on her feet she logged out of her account and left the browser open on that page, hoping to hide her tracks, forgetting that the other browser with the treacherous tabs had been minimized and not fullscreen in the background. Thoughts were running wild in her mind, the picture and mail fresh in her mind while she turned around to greet her sister which must have hidden in her shower behind closed doors, which would explain the lack of sound. Hi Katie! I hope you don't mind that I again checked my mails quickly. You look good. she smiled and hugged her big sister to greet her. At the same time her mind was still running wild, thinking about what she saw. It was a wild guess, but her sister seemingly liked her more than she might have anticipated and a plan grew in her mind. Nothing related to something dark like what she had read but something to test her sister. The hairstyle would be easy to mimic and if she looked through her clothes she might be able to imitate that look on the picture as well. Not with all the shiny stuff but the colors and some of the cut. She would have to excuse herself and go home again, but she was sure she had some fitting clothes in her drawer.
