Sci-Fi & Fantasy

Each step I took down the hall was a little less sticky as the eruption that just took place began to dry. Really I wasn't this stupid, but there was something exciting about what I had just done and no one would really get to know about it but me. I smiled a little to myself.

Author's Note: Requested by Shironomi. Holly wasn't like most centaurs. Most in her age group stood head and shoulders above her, almost torsos above human girls, with some that nearly doubled others.

Sci-Fi & Fantasy

If sleep could be defined as broken, that would not even come close to how terribly I slept last night. I had a massive headache and couldn't somehow get the dull ache in my head to subside as I slowly opened my eyes. There was an odd weight on my stomach and I felt the gut wrenching sensation that every dream I had the night before was real. Every last deta...

Growing Needs Ch. 13

Sci-Fi & Fantasy

She had fucked it up. Mia trotted through her home, ducking to avoid the 'low' doorways, and settled before her tv. She couldn't settle on anything and left it on a random documentary, though her mind stamped any information out, too caught in what had transpired with Rhona.
