As Tim and Jenny heavy into foreplay, Kathy started to become younger.
4 year old Kathy wondered what the noise was in the other room and started to get up. The computer error made Kathy even younger.
Kathy's panties turned into training pants while her sundress now had a picture of a teddy bear on it. 3 year old Kathy was almost to her big sisters bedroom when the computer error struck again.
The training pants turned into diapers and Kathy's sundress disappeared. 2 year old Kathy peaked into her big sisters room. She saw her big sister naked on top of a boy making funny noises. Curious Kathy waddled into the room to get a closer look. The error struck again.
Kathy's hair thinned out becoming wispy as she became 1 years old. No longer able to walk, Kathy continued by crawling toward Jenny's bed.
Jenny was just about to mount Tim when she spotted her baby sister crawling toward her. But before Jenny could do anything, the error made Kathy even younger.
Tim closed his eye's in pleasure as he felt his penis enter Jenny's vagina. Kathy disappeared and Jenny's belly ballooned out. Jenny was now 9 months pregnant with Kathy. The room that used to be Kathy's, turned into a guest room.
"I do not know if this is a good idea", thought Jenny, "I am close to my due date for the baby". But the feeling was to good to stop and continued to move up and down on Tim's shaft. Tim did not notice his girl friends huge belly because his eye's were closed.
As the two lovers moved faster towards climax, Jenny's belly got smaller going back in months of pregnancy. 8...7...6....5....4....3 months. Tim opened his eye's and caught a small buldge of Jenny's belly shrink away.
"Huh..what's that", thought Tim. He did not get to much farther with that thought as he reached his climax and started pumping streams of hot juice into Jenny.
Jenny felt her boy friends penis spasm in her and the hot fluid hit her insides. This caused her to reach her orgasm and she bit her lower lip and threw her head back as the waves of pleasure raced through her.
Inside Jenny's womb, the fetus that was previously Kathy got even smaller becoming a fertilized egg then a unfertilized egg as a sperm seperated from the egg. As the two lovers relaxed in the afterglow of sex, a sperm from Tim struck the egg that was Kathy and Jenny became pregnant once more. Jenny and Tim are now Kathy's parents.
On the computer screen it read, 'subject reached point of conception' reseting parameters. The error disappeared and the program was ready for more changes.
After about an hour of resting, Jenny spoke up.
"Tim you better leave before my mom catches us in bed", said Jenny.
"But what about the program", asked Tim. He was hopeing for more time with the computer.
"No buts, my mom is should be home very soon, we can play with the computer and each other tomorrow", explained Jenny as she started getting dressed.
Disappointed, Tim got dressed and left Jenny's house heading home.
Not soon after Tim left, Jennu's mom, Anna, arrived back from her trip.
"Jenny honey I'm home", shouted Anna grom down stairs.
"Hi mom", said Jenny as she went down the stairs.
"Did you have fun while I was gone", asked Anna.
"Lot's of fun mom, played with my computer while you were out." answered Jenny.
"That's good to hear, help me fix dinner before your dad gets home, okay", said Anna. "Strange it sort of smells like Jenny had sex", thought Anna.
"K mom", said Jenny as she headed to the kitchen.
After dinner, Jenny headed to the bathroom for a long bath. But before she entered the bath, she used a home pregnancy test just in case. "Please no..please no", thought Jenny as she waited to the results, But the answer came back that she was pregnant. "No, this is just great, now what I'm I going to do." ,thought Jenny. She thinks about what to do while soaking in the bath.
Jenny dressed for bed and headed down stairs to watch some TV before going to sleep. Anna headed upstairs and need to use the bathroom.
She spotted something in the trach when she finished using the toliet.
"A pregnancy test?, Jenny was having sex and now is pregnant", thought Anna as her anger rose. She then headed to the Jenny's room to check it out before confronting Jenny.
"What's this?", thought Anna as she spotted the computer. Jenny forgot that the computer was still on. Anna browsed through the program and thought she might be able to use it to teach Jenny a lesson.
