I confess I used to have a 19 year old girlfriend when I was 30 that I turned into a real slut. First it started by making her wear short skirts without any panties when we went out which led to me finger-fucking her to orgasm while sitting in crowded restaurants.
Then I used to have her suck my dick while driving around in traffic so anyone driving next to us could see. That led to me fingering her in public like at the movies, in department stores, parking garages, etc.
One day we were at a scenic lookout by ourselves and I began making her suck my cock. Then a couple of cars full of sightseers rolled up so I started to pull my pants back up but kept going and proceeded to suck my cock until I shot my load in her mouth which she swallowed with a quick smile to the astonished group of retirees watching from about 30 yards away.
Then I started having her give some of my friends blow jobs, I told her I wanted to make a few extra bucks so I told my friends that I would let her suck them off for a fee. That led to me letting some of them fuck her too. She never even asked for any of the money I was getting for letting them fuck her.
Here are some pics. I had a whole shitload but I lost them in a computer that got fried. I thought I put them on disc in case that happened. I got to look around some more, I know they are somewhere...
