I’d be happy to write something for you! I’ve been doing size-based written content for close to a year now (albeit moreso giantess content purely based off the website I’ve posted on before I found this forum lol. I’ve always loved writing giant content as well.) I specialize mostly in NSFW, but I’m more than open to SFW as well. You can see my info and examples below:
