The First Squirt

After being married for a few years I discovered how to make my wife squirt before I had even heard of it.
I am talking 40 years ago and there was no internet and porn was very vanilla - the most daring things were anal sex and toys.
I loved using lube an my wife in fore play and fingering her - this particular time I had my thumb in her pussy and my index finger was rubbing her anus. I could tell she was turned on alot so I pushed my finger deep into her ass. The angle I was at was a bit awkward so I rolled over on my back with my thumb and finger still in and she was kneeling and half sqatting.The angle of my finger changed as we moved and it went deeper into her.
I started to move my hand so I was moving back and front and as she moaned I went harder and faster She was really feeling it now and started to shake and gasp and then it happened - she just started squirting and I stopped to let her to calm down and then started again and she had another sqirt. We did not call it squirting we called a tinkling orgasm.It became part of our regular sex lives after that.
