The die stopped on number 2. Nate flipped to the second sheet to check the number key and was surprised by what he saw.
"Change sex to female? Hah, that might be fun if this thing worked," he said to himself. He picked up the die again, and then dropped it as an intense shiver ran through his body. He gasped for air, and felt himself convulse under his clothes. He decided to follow the advice from the note, just in case, and when he pulled off his shirt, he saw that the die definitely worked.
His chest was normally pretty average for a man- a hint of tone and muscle on an otherwise flat frame outlined with chest hair. All of a sudden, it looked very different. His skin was clearer, softer, and hairless, and his figure seemed to curve inwards subtly towards his navel. But what stood out above all this was his chest- his nipples had swelled up and felt sensitive, and he heard himself pant while seeing large soft mounds of flesh expand around them. His newformed breasts hung heavily off his chest, and he stared at them in amazement.
Soon he managed to draw his focus away from the tingling sensation running down his body long enough to look at his face, and saw a distinctly feminine one- his lips were puffier, his hair longer, his cheeks softer and the bulge of his larynx absent in his narrower neck. Even his arms and legs were shorter and more petite, he noticed. He dropped his pants and removed his underwear, seeing he had developed soft thighs and curvy wide hips, and whined in a high-pitched voice as the changes reached his manhood.
Before his eyes, his manhood turned to womanhood. His penis shrank and shrank, gradually reforming into the tiny nub of a clitoris. His testicles tugged up inside him, altering to form her ovaries. His scrotum sank inwards and split to form the labial lips of her vagina. She barely noticed herself switching from using he to she to describe herself; it felt as natural and right to be female to Natasha as it had felt to be male to Nate.
Natasha picked up the die as she felt the changes finish, and rolled it again...
