I have always wanted to try it..
I knew these 3 girls in college that went to a store once in a while together and they said that the would go in a booth sometimes and suck, taking turns - egging each other on and having fun - but i was scared to go when they invited me. i was a pretty dumb 19 year old... so that being the case - they could have been fucking with me the whole time, except i felt that they were being genuine.
