Memoirs of a Kinky Academic

by IoDyne on Sep 17, 2017
BDSM

This is a work of fiction. The relationships portrayed in this story are also a work of fiction and any resemblance to a person is purely coincidental. Names are removed due to the sensitive nature of the text. Preface I've always had a thing for authority. Any authority will do: police officers, teachers, popes, et cetera. This kink is the quiet passenger...

Fingered at the Game

Exhibitionist & Voyeur

In school I was a cheerleader and what better way for people to look at you than to be cart wheeling, leaping and jumping in front of hundreds of people. Though I hated Home EC I made use of the Susie Homemaker sewing skills. One of the first things I did was make my cheerleading uniforms tighter. Then there were those tights. We had to wear tights under o...

As the senior biology class filed off the bus for its Spring field trip to the city zoo, 18-year-old Brian Swinford found himself surrounded as usual by adoring female classmates. Tall, handsome, athletic, the blond high school student smiled indulgently at the swooning girls; but Brian had a surreptitious eye on someone else. Miss Katherine Limestall stepp...

Serendipity

Romance

Rheumatic fever started it all and set the stage for what ultimately happened. While rare in the United States, the fever still managed to overtake me early in the fourth grade. Complications from the disease proved serious enough that much of my school year was sidelined and my family decided it was best to hold me back a year. Being a year older than ever...

Promises, Promises Pt. 02

Loving Wives

This is a prequel to, and assumes you've read Promises, Promises pt. 1. My thanks to Bad Hobbit for his insightful comments on the original draft. ***** She was perfect, and I hadn't expected that. I was looking for something specific: a straightforward explanation of how enzymes use quantum tunneling to transfer electrons. I wasn't expecting to meet the l...

Markus Haverhill was a man used to getting what he wanted. He was the son of Leonard Haverhill, founder of Haverhill Enterprises. He was heir to a multi-billion dollar fortune. On top of that, he happened to be a six-foot-two, 200-pound, black-haired, blue-eyed Caucasian male in his late twenties. He had it all. He lived in a million-dollar mansion in Los...

It's Friday night and you're staring dumbly at your laptop screen. Jeff and Trip left an hour ago for some party off campus. You can hear drunken yelling coming from somewhere outside your dorm followed by the sound of a bottle smashing against the pavement. Five minutes earlier, you're pretty sure you heard someone throwing up in the dorm bathroom. You shou...

It was her nipples that got me. Of course, I found her breasts themselves interesting enough, but it was truly her nipples that sealed it. The stripper’s tits jostled and cavorted upon her chest like fleshy grapefruits. She was tall too; yikes! the girl must be 6’ 5! As appealing as her toned and Amazonian physique was, ultimately it all came down to her ti...

Group Sex

Andrea was thought to be a very prestigious girl. She was intelligent, quick, smart, yet also sexy, and borderline slutty. She had black hair and almost always wore a maroon tube top and jeans. Anybody with an eye could see she didn't wear a bra, and she liked that. There was a sort of line that nobody dared cross; they were in a university, after all. She f...
