"Hard Fast Dirty Talk Makes My Girlfriend Squirt" by Adam Lanzar is an instructional porn for all men of all ages, from pre-school to twenty-five years old. It will teach you how to talk dirty to a woman so that she squirts in bed, not only with your fingers but with her clitoris as well. There are many methods to achieve this kind of a quick turn on, and I recommend using the "brush on hair method" if you're not experienced. This method requires that you use something such as a soft clean brush, apply it to your girlfriend's hair and move it in a circular motion until your girl has her first orgasm..
