Sci-Fi & Fantasy

In the end, our first day of work together turned out to be a mix of relief and frustration. The relief came when Nancy was able to interact with my coworkers without any embarrassing flubs.

Fetish

Like most women, I was never entirely satisfied with my appearance. I had always wanted bigger breasts - not huge, but... bigger. C cup. Maybe a D. And while I wasn't exactly 'fat', I had always been envious of slender women with narrow waists.

Erotic Horror

Moonlight bathed the forest, a cool breeze rustled through the dense canopy causing the ancient trees to sway eerily in the night. A small deer inched out of the tree line into a small clearing and began to graze on the ground, pulling the roots and grass up with it's mouth then munching slowly. A noise behind it caused it to look around quickly, it's radar...

Erotic Horror

"All sins tend to be addictive; the terminal point of addiction is damnation." -- W. H. Auden * * * "Is this what you want to do?" Once his cum erupted deep within her she fingered and gripped at her cunt and with that all his tautness fled from his body.
