by Adrian_Harper on Sep 25, 2017
Exhibitionist & Voyeur

This is Chapter two in my ED Chronicles series. Although it can stand on its own I recommend that you read chapter one to fully enjoy the buildup for this part. All characters are over the age of 50. ***** It had been several weeks since my first visit to the urologist that led to an injection that resulted in a rock hard erection that lasted for over two...

Fetish

Jason told me to fuck his arse while Sarah went to get Kelly changed. When they returned, Kelly had a studded collar around her neck, had her nipples pierced and was dressed in a similar bustier to the one I was dressed in. She'd also let her nose and tongue be pierced. Sarah sat in the armchair opposite us and opened her legs to Kelly's tongue. "So Kelly...

Luanne Ch. 04

Mature

I wrote three chapters of the Luanne story and figured I'd just continue describing individual sexual encounters, but that all changed four months ago -- that's when she ran into Quint.

But suddenly she stopped talking. So I gave her a couple of hundred to tell me more about what went on at that place, and she proceeded to tell me the story of scienc...

Erotic Couplings

I love everything about my job, the uniform, the people, and most of all the sexy guys who have to come in to hospital for one reason or another. I was working in the department where the guys were in for erection problems. This one guy was so good looking you would never have guest he had trouble rising one. His wife was a right bitch saying things like h...

My Korean Hottie Ch. 08

by TheKeith on Nov 7, 2017
Interracial Love

To my readers: the 'cure' for impotence described in this episode actually does exist - I was diagnosed with this condition about 12 years ago - the injection of bi-mix takes place along the side of the penile shaft, which is not nearly as sensitive at the glans of the penis - I have therefore had between 80 to 90 injections per year = just over 1,000 inject...
