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. Her mother was one such centaur, several feet of legs that supported a voluptuous torso with tits half the size of Holly's whole body. All that said, she didn...

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.

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. No one had denied her like that, or at all, since this ridiculous growth spurt start...

Light from the tavern spilled out into the muddy road. An old villager, drunk and half asleep, leaned against the wall beside the door. The old man didn't want to make the ten minute walk down the hill to his home where an angry wife awaited him. The sounds of cheer from inside the tavern kept his spirits up and helped him ward off the encroaching specter of...

Humor & Satire

Nevar was getting restless inside Jordan's perpetually on computer. Jordan had gone for the whole body modification thing pretty willingly, even when it had been pretty damn disruptive, but since he'd found a willing slut in Dennis, things had pretty much stagnated.

Fetish

Will and Tamara both mustered up the energy after their morning love-fest to get dressed for Will's 6th and final appointment. Will could only watch as Tamara propped herself up and jumped off of the edge of his bed. The vicious bouncing of her head-sized boobs sent Will into a trance, as it took several seconds for her chest to stop bouncing and settle into...
