* * * * * Click Here to listen. (9 min/mp3) * * * * * It was nine at night and I had just gotten out of the shower, my body still wet with beads of fresh water. I was feeling refreshed and looked forward to just relaxing the rest of the night. I was contemplating going on the net to my favorite erotic story site. I had a tingling in my nuts and going on L...

Submissive Futanaries Pt. 01

Transsexuals & Crossdressers

AN: This story is purely fictional and fantasy. This is all from my mind, though I know of a futanari's libido and such after lots of googling and doing old roleplays with a few actual futanaries. In my stories, don't call their extra appendages 'cocks'. I use 'futa' since I am more comfortable with that. If you don't like it, then stop reading. And complain...

To all My readers out there thank you for the response. I do wish I had an editor even just for the spelling I have run it through spell check and picked up a lot but as I read it and try to pick up the mistakes I get lost in the story and my mind sees what is not there. If any of my readers would like to take on the spelling i would appreciate the help. **...

Maria's Good Turn

by IgneousRocks on Sep 13, 2017
Mature

Not much sex. It happens. A straight forward story of how one person may have dug deep to discharge her sense of obligation. This is a product of my imagination. Any resemblance of characters living of dead is purely coincidental. Maria "Hi, Bro!" "Hi, sis. Twice in one day. To what do I owe this honour?" "Remember Dad's old laptop? I took it after he di...

Pop Star's Brother

Bryan Spears stared at the computer screen and made a fist. How could anyone be putting fake naked pictures of his sister Britney all over the internet? He went from one website to the next looking at countless numbers of fake Britney pictures. "Damn assholes," he said under his breath. He stepped away from his computer and went to lie down on his bed. It...

Exhibitionist & Voyeur

My (now ex-) wife and I used to visit her sister Kathy quite regularly. If either her son or daughter's bedroom was available, she and her hubby would let us have their bedroom and sleep in one of the kid's rooms. Such was the case on this particularly memorable visit. I knew she and her hubby were into porn, as he invited me to check out some of the video...

Erotic Couplings

Ok second story. Going for a multi-chapter one this time. Hope you enjoy! (The crack will become more prominent as the story progresses.) EDIT: Turns out I fucked up on perspective towards the end. Edited to at least all be in 1st person. My bad! There's a crack in my bedroom wall. It's not obvious, mostly hidden by my headboard, but it's there. It's not w...

Goodbye Sis, Hello Bro

by Deborah on Sep 16, 2017
Humor & Satire

("Goodbye Sis, Hello Bro” is yet another true episode in the sexual story of my life. I am purging my soul. Telling of my past "sins" is part of my repentance.) "Goodbye Earl" by the Dixie Chicks made it big at the Country Music Awards. "Goodbye Sis" is my favorite tune. Kevin and I met online. We both frequented a certain erotic bulletin board. Soon frien...
