A list of Giantess-focused manga that I have read, for anyone who wants suggestions. Feel free to leave a review with any series that I missed.

I'm planning on combining all of the chapters into one list at some point, but first I have to reformat/rewrite the first chapter

Diane becomes jealous and frustrated over Elizabeth's relationship with Meliodas. The giant woman wants her captain to take a sexual interest in herself but he is too focused on Elizabeth's boobs. Diane decides to take her human-sized doll out into the forest for some personal alone time. However, Elizabeth follows her and then accidentally gets mistaken for the doll when Diane begins pleasuring herself. She then continues to use her friend as a dildo completely unaware of the girl's struggles.

Actions that can't be changed are taken and all sides must adjust

Your Giantess Girlfriend sucks your cock! I wrote this story based on a picture inside and I thoroughly enjoyed every second of it.

(Formerly titled "Giantess/shrinking & farts - Spending time with 'Auntie' Sheila")

One day, for reasons that escape your comprehension, you shrink really small (ranging from about 1/2 inch to 1/10 inch or 1cm to 1 millimeters approx.), and you don't really know why. Did someone do it? Did something cause it? Who, or what? Unfortunately for you, you won't get many chances to find out, as you have to try your best and survive as you're not alone. The girls that you were just hanging out with or happened to be around are now seemingly impossibly gigantic. You might try to alert them of your presence, but that might not end up being the best idea.

[This story is sort of a spiritual successor to TinyMan0001's 'Giantess/fart shrinking' stories, though not intended to be a carbon copy of it. One difference is that whether farts shrink you is up to whoever is writing, though I at least chose to leave the cause of shrinking mysterious at the beginning, and also because it slightly contradicts some backstory (I also left open the possibility for a girl to intentionally shrink you). However, like it, it's largely focused on the shrinking side, though I guess I can leave a branch dedicated for a giantess/growth route if anyone's interested on adding to that. Also, similarly, the girls may be aware or unaware of your shrunken form. Usually, I'd say they should progress from unaware to aware, depending on the girl and the situation though.

This story is a more user-friendly display for the interactive I made at Writing.com, though here we have to do away with the ability to have other people directly add chapters, and instead I'll be posting the more relevant routes done so far.

PS: The Giga tag was just selected in relation to the main character's perspective, this is mostly a shrinking story, not growth focused, though a growth route may be done in the future.

Awake in a world of nightmares, Anton struggles to maintain his sanity against the creatures torturing the populace.

Do you understand the reason yet, rabbit?

A lady celebrates her 21st Birthday, her mother has given her the gift of 21 shrunken men to enjoy... and she wants to have a very special and diverse time with them. This story explores lots of different giantess/ shrunken themes ranging from gentle to violent. Enjoy!

This town had been a living hell for them both, so they returned the favor.
