Evelyn – my gorgeous teen sister

I have a sister, Evelyn. 19 years of age, Evelyn is two years younger than me. She is a good girl, always getting high grades, not at all the party-type. She and her geeky friends usually hang out in one of their rooms on weekends, doing who-knows-what.

Evelyn is a very pretty girl, too, although she doesn’t realize, and definitely doesn’t act like it. I don’t know how she does it, but she’s always had this amazing body. Now, I happen to be a sucker for bodies.

It has taken me a while to accept the fact that she turns me on. At first, I tried killing any unholy thoughts right when they popped into my brain, and succeeded most of the time. But the older Evelyn got, and the more her body started to look like that of a woman instead of that of a girl, ignoring her looks wasn’t so easy any more.

As soon as I realized I couldn’t resist, I became obsessed. I would look at her for hours on trips to the beach. I’ve taken hundreds of pictures while she was getting a tan in the garden. And it became worse. I snuck into her room at night to look at her wearing pajamas, or, in summer, just underwear. I spied at her when she was taking showers, climbing on a chair to be able to look through the tiny window. I searched for hidden folders on her laptop when she was out, hoping to find the slightest evidence of her having a naughty side, but failed every time. I had to be happy with my own observations. But I wasn’t.

One very hot week in summer, when my parents were on vacation, I decided I had to take matters into my own hands. Obviously, I couldn’t just ask her if she was interested in not being brother and sister for one night. I needed to persuade her with something more tenacious. I got online and ordered something I never thought I’d ever order.

The day the package arrived, Evelyn and I had pizza together. After we were done, I went to the kitchen to get us something to drink, before we would clean up. I took the little tube out of my pocket and emptied it in her glass, then brought it to her. She drank all of it, thirsty as she must have been.

After a while, she started to look tired. She didn’t feel so good, she said. I let her lean on me and brought her upstairs, to her bedroom.
