Opinions are divided on this matter, but he does not plan to grow it any further.

I sure hope so. What are brothers for afterall if they cant help their little sisters.

I feel like his body should stay small but his cock and balls keep growing because his little sister has been mixing her milk and cum with some of his food without him realizing it

I prefer brother to stay small. He is too big as it is already 😅
犬帝国
Her brother will probably help out.

I'm thinking about how big to make Futanari-chan's brother.
犬帝国
Thank you! She's growing bigger and bigger.
Nazrax
Hopefully he needs to help her with her boner
qwerty
Hope big brother keeps growing but he's still not even close to his little sister in size
