Mandy was watching her son Cody grow up so fast. He was 18 and nearly off to college. He had a full long beard and wore tight black pants but wore them very low to make room for his manhood. Mandy had been feeling depressed seeing him grow so much, she couldn't bear to see her little boy getting older, moving on, and this part of her life ending. It didn't really hit her until just last week. She had come home early and her son was in the shower. She was walking past the bathroom when he swung the door open and stepped out, dripping with water. She stared in shock at the mass of muscles and hair, chest, face, then the jungle of pubic hair, and out of it sprouted a gigantic, leathery, shaft, 7.5 inches long and as thick as a beer bottle, dangling with a head that was thicker that the whole thing but pretty short, like the top of a muffin.
She expected him to cover up in shame and apologize, but he just said "sup, Mandy" and started to walk past her, not even calling her mom. She watched wide-eyed as his heavy cock flopped from thigh to thigh as he walked, it almost seemed like he was intentionally boosting it with his thighs so it would bounce and swing more. Maybe he just does that subconsciously. She remembered how loose and wrinkly the skin on the circumcised shaft was, you could tell it still grew a lot more and had stretched to that size many times.
That same night his little slut of a girlfriend Dani came over, she was wearing a mini skirt assumedly to remove one step of the undressing process and no panties for another. As Mandy lay in her bath trying to relax she heard her start to cry out from his room.
"Wait, stop, it's too painful!"
"But you've taken like every dick in our grade" Cody complained
"Yeah" Dani retorted "But you don't have a dick, you have a COCK, and it's the most massive, manly cock I've ever seen."
Mandy's face flushed red, don't they know she's home? she felt the head of her clitoris start to swell like a big juicy corn kernel. she started to rub it absent-mindedly.
"Don't you want to be the woman who can take the biggest cock? It'll be painful at first sure, but a real woman can take the pain and handle a real man. Leave the tight holes to the little boys"
Mandy realized that she could only fit two fingers inside of herself before it became painful. Did her own son just say she wasn't a real woman, that his father's 5 inch dick was that of a little boy? She defiantly tried to fit three of her fingers in, stretching her labia like a strained rubber band. She winced and gasped
"you're right, put it in as deep as you can!" she screamed "and when you get it up to your balls I want you to come inside me!"
Mandy wondered just how big Cody actually was up there, 9 inches? 10 inches? 11? Was it even possible to get it in to his balls? This slut thinks she's so hot just because she can take a giant cock? Well, mandy spread her fingers apart inside her vagina, trying to widen it more.
"What?! You could get pregnant!"
"I get off thinking that you might leave some of your huge cocked offspring inside of me!"
What an idiot, Mandy thought as she came, both of them. Confused by their adult bodies they don't realize that they are still immature little children, she thinks she's ready to bear children just because she can take a big penis? She realized what Cody must be doing, traipsing around nude, intentionally having loud sex. He was indirectly trying to tell his mother that he's grown up, done with her, and asserting his dominance and power by treating every space like his own and ignoring others. she hated that it had worked for a moment and she had gotten herself to climax thinking about her son as a real man, as if that's how a real man acts. This isn't adult behavior. It's the behavior of an arrogant child. Mandy realized that Cody was too confident in himself because of his giant cock and muscles and that the only way to make Cody see what a child he still was would be make his body like a child's again so he won't be able to trick himself and others into thinking he's an adult. Then she could continue to care for him until he's really ready to grow up. She ordered several products through the mail and waited for them to arrive. she could easily slip them into his meals. One treatment was designed to shrink the subjects genitalia, One is designed to shrink his skeletal system and make him shorter, one would degenerate his musculature, one was a brand new hormonal treatment that would shrink his vocal folds and adams apple, as well as undo the growth of his body hair. There was a whole smorgasbord of other amusing treatments in her order as well.
