Bio:

As someone who loves both creative writing and the giantess fantasy, I hugely enjoy contributing to this community.  My works vary wildly from the pleasantly gentle to the fetishistically cruel, and I hope to explore everywhere in between as well.  The most prevalent subgenres in my stories are feet, mouthplay, and taboos, those being my favorites, but I try to add variation to keep them entertaining.


Want to commission me for a custom story? I can write your ultimate macro fantasy, from a wide range of genres and lengths. Read details here: https://thejacksmith.deviantart.com/journal/Story-Commissions-698491757


I also have a side-shop for miscellaneous pre-written & discounted goodies, such as flash fiction, unfinished tales, and deleted scenes from series like Time-Out and A Little Blackmail. Check it out here: https://www.deviantart.com/thejacksmith/journal/New-Special-Stories-Shop-802615692
