Jennifer squealed and snorted, "For your transformation, you will transform into whatever shape you most desire OINK! and for your dare, I SQUEAL dare you to immediately ask me 'transform or dare' and SNORT transform me into the shape I most desire 'cause I'm you're OINK! sister!"
Megan stood there then suddenly felt her shoulder broaden as she grew taller and her breasts shrank and she reached down between her legs and shrieked, "Omigod, I have a penis!" as her voice dropped three octaves. She then looked into the mirror. "I'm Morgan Beech!"
"Who's that?" snorted Jennifer.
"This hunky guy in my chem class and-- Transform or Dare?" she said as the curse suddenly stopped her from babbling.
"Transform!" snorted Jennifer.
"Become whatever you most desire!" Morgan said and watched in horror as his sister began to morph into what she, as a flatulent pig woman, most desired: a giant hot fudge sundae.
