My story is actually a fun one I think. A bit ridiculous, but mostly fun. My name is Katrina, and this is how I found my sexual paradise. My young life was nothing interesting. I...

Gym of your Dreams

Fetish

Something about Goliath Gym is special. Whatever your goals may be, Goliath Gym is here to make them come to life. At least, that's what the billboards and TV ads say. The building itself is nice, but nothing out of the ordinary. Two stories of concrete and class in a regular strip mall on the decent side of town didn't exactly make it stand out as "spe...

Transsexuals & Crossdressers

I was never what anyone would refer to as the typical male. Standing only five foot five and weighing only 130 pounds, no one would ever use me in a he-man advertisement. I wasn't scrawny; my body was well formed with some muscle in my chest and legs. My physique hasn't really changed at all since I was 15. Getting girls in school was not the easiest since t...

A Stretchy Situation (Side A)

Sci-Fi & Fantasy

Warning: this sexually explicit story about three superhero spies having a relationship dispute is very skewed towards femdom as he finds himself in trouble with both of them. It features elastic ladies as well as breast, butt, clit, hip, penis, and vulva expansion, women's muscle growth, and some very intense facesitting. If any of that sounds like somethin...

Fan Fiction

In the quarters of Zatanna the Magician at the Hall of Justice, the woman sat at a table surrounded by trinkets and books that she had been collecting for some time, not for any dire situation really, just a hobby really. NONE of the items were dangerous, not by any stretch of the imagination but they were certainly powerful. One was a crystal ball that told...

Megan Ch. 02

Fetish

Ch. 2 The Bar We went to the nearest quite bar that I could think of in a hurry, attracting every single view along the way, which was not quite surprising. Obviously, Megan was an eye-stopper being as tall as she was. But, at 8'4" in her heels, it was over a certain psychological limit, not to mention that her body would be impressive at average height, sp...
