Marie is my little sister, but she's incredibly cute and has an amazing capacity for understanding! I can't help but feel lustful towards her... Even though I'm supposed to be the older brother, it's pathetic, and that's absolutely not okay! Just when I was lost like this, a female transformation drug came into my life. If it's between women, it should be fine, right? But once I transformed, I found out how good a woman's body feels...
