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. 

Faelyn, A mage from a faraway kingdom, came to the remote city-state of Idosa to extradite what she perceives as a criminal, but she has a surprise waiting for her.

Mark and Carol have been boyfriend and girl friend for a few years, and are getting ready to go as a couple to a Halloween Party. This year they decided on some themed costumes, but with a little of Carol's magic to spice things up. However, when they arrive they discover that Carol is not the only magic user having some fun tonight, and so Carol and Mark get to experience a number of different reactions to the odd situation.

Bridget always thought having a titanic knight to protect her kingdom would be the way to go. So when she met one she did her best to enlist them...

Sometimes the eyes look where they shouldn't... but what's the harm if both sides don't mind! 

Jasalean and Murack have been travelling together for a while. When Jasalean catches Murack staring at her backside... she offers to let him stay there for the rest of their trip!

How will our hero answer?

You try to sneak into your girlfriends room late at night for some fun role play. You're nervous because you've never done anything like this before.  Before you know it, a flash of light hits you and you find yourself zapped into a new world of monolithic structures and mountainous beings roaming around you.  

Will you be able to get to her in time?

A shrinking story told from the perspective of Billy Little. An odd character, that happens to stumble into something that will dramatically change his life forever. It's an extremely detailed depiction of his nightmarish episodes. This is just the beginnings of something so much bigger than Mr. Little. Because, before he realizes what's actually happening, the entire world has already changed into a completely different humanity.

Here's a bunch of short giantess thmed stories that I wrote in under 30 minutes. Most of the stories will be based around foot fetish stuff so if you're not into that, here's a quick warning. 

(The first story is a multi-parter btw)

In a cold night, a young man comes across the tent of an alluring fortune-teller. Unaware of the danger, he is about to come across a mystical world of magic that will forever change his life.
