"I wonder what Kathy looked like when she was my age", thought Tim as he pulled up Kathy's age list and selected 16, keeping Jenny at a 5 month old fetus.
While Kathy rested, she began to grow younger going from middle age to college. Her breasts firmed up and became slightly smaller. Kathy's nose started to turn upwards as she reached her teenage years and her hair became a brighter blonde color. Her maternity dress changed to a more teenage look. The wedding picture besides the bed changed from Kathy being the bride to a woman who looked a lot like her mother besides her former husband now father.
Back in the guest room with Tim, some more changes were happening. The room was turning into a teenage girl's room. Posters of bands that Tim knew his fellow classmates listened to appeared on the walls. A picture appeared besides the computer on the desk. Tim got a shock when he saw the picture.
"That's me next to that blonde hotie," Tim said quietly.
As Tim stared at the photo, the room's door opened and in walked the girl in the picture with a slight change, she had a 5 month pregnant belly sticking out.
"I do not know why I was in my parents bedroom," questioned Kathy. "Timmy thanks for comng over, but it's a good thing my parents are out of town until tomorrow, my dad is still mad at you for getting me pregnant."
"Your beautiful Kathy," Tim said looking Kathy up and down with his eye's. He started feeling his penis growing stiff while he was looking at his dream girl come alive.
"Your just saying that, look at me, I am fat and ugly," cryed Kathy.
"No your not, your still just as beautiful", Tim said while he started sporting a huge tent in his pants.
"Really, you still like me", sniffed Kathy. She then glanced down at her boyfriends huge boner. "Too bad that I have this belly in the way or we could have some fun", sighed Kathy.
With his hormones flooding his mind and not thinking striaght, he reached for the computer to make things easier for them to have sex.
He clicked on fetus Jenny's list and selected 0 by mistake instead of 1 month. Tim did not notice his mistake because he turned to look at Kathy. Her belly bcame smaller as her dress got shorter. Soon her belly was flat and she was wearing a short dress.
"Stop playing with my computer, I am very horny and we have the house to ourselves", said Kathy while she dropped her dress to the ground exposing her firm breasts and silk panties.
Withour another thought, Tim got up and kissed Kathy on the lips while his hands moved down to her firm buns on her rear. Kathy started to unbutton Tim's pants while Tim slid his hands under her panties and pulled them down. They only broke their kiss for Tim to remove his shirt while Kathy pulled his pants and boxers down. Soon two very horny and very nakeed 16 year olds were fondlings each other on Kathy's bed. After a few minutes of foreplay, Tim moved his erection towards Kathy's very wet bush. Meanwhile inside Kathy's womb, a very small embryo of Jenny grew even smaller. Soon Jenny was just a fertilized egg, but that changed as Tim and Kathy approached orgasm. The fertilized egg spilt sending a sperm into the darkness of Kathy's womb. Kathy was now not pregnant anymore, but that was gong to change very quickly as both Tim and Kathy orgasmed. Tim shot his load deep into Kahty, and one sperm out of millions made it's way toward the unfertilized egg. Kathy became pregnant again as the sperm merged with the egg and began life anew for a future girl named Jenny.
The two lovers basked in the after glow of there love on the bed. After about 10 minutes Kathy realized something.
"Timmy,I forgot to take my pills, what if I get pregnant, my dad will kill me", panicked Kathy.
"Oh no.., I am not ready to be a dad yet," thought Tim as he jumped out of the bed and went to the computer.
"What are you doing Tim?," questioned Kathy
"I am going to fix this," Tim answered back.
