As Jeff wrapped his hands around his mother and she wrapped her hands around him, and then the chronivac went to work. His mom was slightly shorter than him, but she shrank a few more inches Jeff was able to look down at her a lot easier. The lines in her face vanishing, her hair color becoming more vibrant. Her body was turning into that of a cute girl around Jeffs... no slightly younger than Jeff's age. She looked up at Jeff as they embraced and Jeff could see her face was considerably different. It was almost like she was a different person. The clothes she wore also changed a bit, the robe shrinking a little and the pajamas turning into a cute pair of panties and bra that were ocean blue and a little frilly. Jeff's mom smiled up at him, but Jeff could feel that wasn't the end of her changes. Mostly because they were in a tight hug and he was feeling something pushing into his torso. As he looked further down it seemed like her face was getting a little further away as her breasts seemed to grow larger and larger. The bra containing them obviously growing, but her robe seemed to be shifting. The neckline retreating showing off more and more cleavage. Her breasts turning from perky small things, to small hills with a small plane in-between, to two large hills with a small valley in-between, and at this point they were mountains with a canyon in the middle. Jeff wondered about something and let his hands drift lower and he coped a feel for the girl who was his mom's ass. The girl let out a small moan, and the flesh was taught, a little soft, but basically nothing when compared with her boob flesh. Jeff however could feel her ass flesh growing in his hands, filling up his palms, and turning nice and jiggly.
"If you're feeling a little frisky how about we go back to bed?" asked the soft sweet voice of the girl. Jeff obviously felt a little hard, but realized this was just supposed to be a test and he didn't want to fuck his mom... Although the longer he looked and gropped the less he could realistically call this individual his mom. Especially as she seemed to be trying to angle his errection with her thighs towards her crotch. Jeff let go and turned around as he said "I think I've got to get to the bus stop soon!"
His mother's voice called out "Alright, well have a nice day at school." the really busty young girl having yielded her existence to the woman who had come before.
Jeff with his backpack went out the door hoping soon his erection would calm down by the time he would get to the bus stop.
