Suddenly Dan grabbed his gut in anguish. "What...did you do to meeeEEEEE--", he spoke as his voice pitch suddenly started sliding upwards, along with his height decreasing. "I've always wanted a sister", Kat grinned, "especially one that I could tease more than a little bit. So, enjoy being teased by me for a long time to come...Danielle." She cackled evilly and watched Dan shrink, whose face and body had lost all muscular distinction, his teeth forming back into milk teeth. His nails grew out a bit, and hair flowed across his miniature shoulders. He was practically limping around now, feeling an unbearable twisting in his groin, which suddenly stopped as it felt like it shot up into his - now her - stomach. Kat watched "Danielle", who had now shrunk to the size of approximately a ten year old, with glee:"All the defining features to form your sisterhood are there...now let's just do something about the outer finishing. Danielle's old clothes shifted into a neat little dress, almost as if made for wearing to her sister's birthday party, and her shoes changed into little mary janes with white socks. Her hair flowed straight backwards, held in place what she felt was a big light pink hairband.
She ran out of the room crying, "I'm telling mom!", to which Kat idly replied:"Tell her what? There's as much memory left of the old you as there is of your room...which you may want to check out." Danielle clopped on her new shoes through the house, hysterical and unsure where to go.
