"D-dare!" Kyle said, quickly.
Jennifer smiled. "Oh, I hoped you'd choose that. Are you paying close attention? Because this will get pretty complicated. First, all your shirts and pants will change into short dresses, going no lower on you than mid-thigh. Next, you won't be able to wear boy's underwear, you have to wear either panties or a diaper... which brings me to the next part. You will no longer go to the bathroom like a big," (She paused with a sly smile), "girl, you will lose all control of your bladder."
"Oh," added Jennifer, as an afterthought, still smiling at Kyle's expression of shock and horror, "and before you start changing, you will ask me transform or dare, and dare me to laugh in your face."
"T...transform or dare." Kyle said, trying to resist.
"Dare!" Jennifer said, confidently.
"I... I dare you to laugh in my face." Kyle said, defeat obvious in his voice as Jennifer's derisive laughter rang throughout the bathroom.
