Changing the rules a bit

After experiencing such a growth suddenly, Tom thought maybe it’s best if he altered the rules a bit. As much as he loved the idea of him being absolutely hung, he’d prefer if he knew about it…

Maybe if he made it so the added rules are ‘old rules’? That way he’ll have new memories of the changes. He’ll make it so he always has had a huge cock like now, it’ll also make his sisters not be as shocked when they see him.

Yea! That sounds like a great idea! Tom reached for his pen and added something to the rule he wrote:

New rule: "Any kink that Tom's family member share will write itself into the Rulebook, if at any moment any of the family members (implicitly or explicitly) want to undo the rule, it will remove itself from the Rulebook" “rules written in this way are old rules”

Tom smiles as his plans come to fruition, he sees the new rules he got change to old rules. The text shift and reforms in front of his eyes. This rulebook rules!

He remembers how his cock grew so big once he hit 18, explained away as ‘second puberty’. How his first time with his moms made their bond tighter, how the triplet’s first time ended with them flooding the whole house and got in trouble
