I jill at work
I play with myself at work and it is not like I have a lot of privacy. There are cubicles and I am on a corner one at the end but there is a lot of walking traffic in our department. Sometimes I just simply play with my nipples but I have gone as far as a dildo up under my skirt and even had to carry on a conversation one time with it halfway in me and my legs together holding it against my chair.
I have had some really tremendous orgasms from what seems like hours of teasing myself, luckily for me I am not one to have loud ones.
