I Did Something Stupid, I Made Out With My Step Sister

So there was a big family party a couple weeks ago and I did something kind of

stupid. I made out with my stepsister. We didn't actually have sex or anything but

ever since my sister's been real weird. At first I shrugged it off as a phase

but then I found a pair of panties on my pillow and they were wet. Then I started

to worry. There she was my sweet stepsister. A real psycho.
