Karyn stared down at her large, alien appendage in shock. "Jon!" she said.
...but her words were cut off when Jon knelt down and started sucking on her new cock. The experience was new to her, and highly arousing. She was overwhelmed with the new sensations, and couldn't concentrate on anything else until she spurted hot cum into Jon's mouth, making him gag.
Karyn collected herself as Jon couched and hacked, wiping his mouth in disgust. She thought for a second, trying to figure out a wish that would fix her pre-dick-ament. She knew that she couldn't make the penis go away, but maybe she could change things so that it wouldn't be a major problem.
She grabbed the stone out of Jon's hand and said "I wish that this penis will shrink down to a tiny size every time I come, so my genitals will look like normal female parts, and that it will only grow back to full size if I pinch my nipples twice and rub myself down there!"
Karyn looked down, hoping that the wish would work. She didn't want to spend the rest of her life as a freak with giant boobs AND a huge penis. She sighed in relief as the stone glowed briefly, and her penis shrank down and disappeared in the folds of her vagina. She dropped the stone on the ground to take a closer look - her clitoris now looked like a tiny penis, but she hoped that nobody would ever notice.
Jon said "Geez Karyn, I'm really sorry - I don't know why I wished that!" He picked up the stone and started to get dressed.
Karyn started to get dressed, too, and said "You need to be more careful with that thing, Jon! I think I might be able to fix my boobs and hair, though - let me think about it, but let me borrow the stone later, OK?"
Karyn gave Jon a kiss and headed back to the school. Jon straightened his clothes and headed back a minute later. Jon headed for his first period class, which was P.E. Just before he walked into the gymnasium, Mrs. Butterfield, the elderly school librarian, grabbed him by the shoulder. She whispered in a raspy voice his ear: "Jon, come to the library at recess - I have a sexy surprise for you!"
Jon's eyes widened. He hadn't meant for the wish to make the staff hot for him! He ran into the locker room and started getting ready for gym class. He pulled the stone out of his pocket, thinking that this was a good time to fix his earlier wish. He said "I wish... that this penis will shrink down to a tiny size every time I come, so my genitals will look like normal female parts, and that it will only grow back to full size if I pinch my nipples twice and rub myself down there!"
"No, wait!" he said, "where did that come from?"
The stone flashed and Jon felt a strange tingling feeling in his groin. He pulled out the waistband of his pants and saw what looked like a girl's parts down there!
