When Kate entered in her son's bedroom she found him sitting on his bed and looking up to her, she then noticed that something was wrong with her son when he stand on on his bed, he looks smaller, usually Jake is like 4ft and half but now, he looks like 3 foot tall, not only but when stood up on his bed his shorts and briefs fell down to his feet and since he only sleeps wearing only that he was now naked in front of his mother and not only that, Kate look down to his crotch and saw that he was fully erected.
"Jake are you ok?" asked Kate looking at her son.
"Mom what happened to me?..." said Jake scared looking at his mother. "Why I'm smaller?!" exclaim Jake trembling not even noticing that he was naked.
"Oh baby is ok..." said Kate as she walks to her son and lift him in her arms as she took a seat on his son's bed and sitting Jake on her lap. "Is ok baby, mommy is here, don't be scared." said Kate caressing Jake's back with her hand, trying to calm him down.
"Mom." said Jake as he rest his head on his mother huge boob, for some reason it feels so nice being on her lap.
"Strange, I thought that he was going to grow not the other way around, he looks so cute, so defenless and not only that, it seems that he is still shrinking, I can feel him getting smaller on my lap, this feeling is so nice..." thought Kate as she looks down to her son's penis. "My my what a interesting side effect we have here." thought Kate looking down to her son's erection as she smirks licking her lip.
"Mom..." said Jake as he looks up to his mom's face and he noticed that she was smiling to him. "Why did I get small, what is happening to me?" asked Jake concerned to Kate.
"Is just one of my experiments honey, a size formula, don't worry about it, we just have to keep experimenting with it." said Kate.
"What do you mean mom?" asked Jake.
"Well baby if you haven't noticed it yet, the formula is still working on your body, you are more smaller than a moment ago." said Kate smiling to her son.
"What?..." said Jake as he looks at his body and noticing his change, he was more smaller than before, he was like 2 foot tall now, he then look back up to Kate. "Mom we have to do something, I don't want to shrink anymore!" exclaim Jake now scared with his voice acute.
"Now baby, don't be like that, don't you want to help mommy with her experiment?" asked Kate in a motherly tone.
"But what if I get too small?" asked Jake concerned.
"Come on Jake..." said Kate as move her free hand to Jake's crotch, caressing his erected penis in a slowly manner. "Don't you want to help mommy? I promise that I can give you whatever you want, you just have to listen to mommy." said Kate in a seductive tone.
