Fixing the straights

by cdbaby on Dec 28, 2016
Gay

You wake up and prepare for your day, unaware that this would be the last day you would be considered straight. You shower as you did every morning and felt the water's warm touch as it cascaded over your skin. You could stay here forever if you could. But you need to start your day and the hot water would run out before long. You wash your hair, then the re...

Gay

John was a good looking guy, but always felt rather generic and lost in the crowd in his home town. He was of average height at 5'10, and at 25 had a trim hairy body with sandy brown hair and blue eyes, he was very much an all american guy. The one place he wasn't average was his cock, which was about 7.5 inches long, quite thick and circumcised. When it cam...

Gay Male

*** Sarkopheros Says: By now I've put out a good number of stories focusing on straight sex. We're taking a different tack today! Instead of writing a tale of straight erotic drivel, this is a tale of gay male erotic drivel. As with other Jae stories, hentai physics are in full effect. I do not understand things like "basic human physiology," "common sens...

After it infects the entire research team resulting in their quarantine, experiments are performed in a lab deep in the mountains of the United States.

It was a Saturday in the early part of December and the eight soon-to-be-players were stuck at school, of course not by choice, but because detention always claimed its victims. Mr. Brown, one of the school's science teachers, led the group of seniors to the Study Hall, a windowless room where the were to serve their time like inmates. What none of them knew...

HELLO READER. I am no longer maintaining this story on this site. This story was taken from a free WIP game that I am developing. The features in that game no longer fit easily into the CHYOA format. To be clear, CHYOA is awesome, I just don't have the drive to maintain two versions of the game. You can play the game online at https://unrulydogboy.itch.io/de...

Eric tossed and turned, unable to stop thinking about his last call of the night. He'd seen a lot of weird things in his time as an EMT, but something about the naked, burly man passed out on the sidewalk had pushed the encounter to the top of the list. A tenant in one of the squat apartment buildings lining the street had called it in, saying they saw the h...

Gay Male

Despite his impressive body, the fit young man still looked awkward as he stood in his boxer briefs in front of the mirrors that reflected him from all sides. Will didn't mind the view of his chiseled frame, especially the way the light grey fabric of his underwear accentuated his tight bottom and thick bulge, but he wasn't used to being prodded at while so...

Gay Male

Arthur was working out in the local YMCA gym. He had been lifting weights for months but no matter how hard he tried he couldn't build any real muscle. He had developed some nice little abs and some nice little delts and a nice little core and some nice little biceps. When he complained to his friends they couldn't understand it, he looked in shape to them....
