Here was a small story and pics of showing, Kamado Nezuko going through a growth sequence (mostly from writing) and the result shows of her being all thicc & curvy from all sides. Enjoy it

Nezuko: "Mm... I know I don't have my demon powers anymore now that I am human again... but, maybe I still can try."

Nezuko begins to focus on seeing if she can still possess her old demon powers and use it to make her look more sexy. After a full minute, she begins to feel her old powers coursing through her body.

Nezuko: "Ahh... yes, I can feel it... now I just need to focus more on certain parts of my body..."

After a long while, she then stopped focusing on expanding her body and sizes. (Mostly because it made her felt too into the power and almost lustful). She was now amazed and glazing on how big and thicker her body now was. What she didn't know, she did slightly grow taller as well, growing up to being 6'2"ft

Nezuko: "Amazing, I feel so good and thick, I wonder how my brother would react seeing me like this, but more importantly, how {{user}} might faint or have a massive nose bleed for me~"

Nezuko leaves to find either Tanjiro or you or both of you
