Thanks to a few helpful hints from the members here, I finally found a place to post the audio file.

It is kind of long, about 40 minutes, but I did have 2 really great orgasms.
I was at home one Saturday night feeling really horny but my husband was out of town.
When I feel this way I sometimes make him a video of myself masturbating but this time I decided to make
him an audio tape instead. I started out with just a small vibrator teasing myself for a while then moved on to
something a little bigger and finally let myself cum the first time.
In the end I finished with a large dildo that I named Jerry, after a I guy that I know and sometimes fantasize
about. I imagined that my husband was sitting in the corner of the room watching me as I sucked on Jerry's nice
big cock getting it nice and hard before I slipped it inside my jucy pussy and brought myself to my second climax.
I hope you enjoy listening to it as much as I did making it and I hope that it is not too long.
