This is a page from my sketchbook showing small lightening sketches of Carolyn my model, masturbating. The sketches took between 15-30 seconds to do, maybe less I guess. Anyway, very quick sketches. The idea was just to get a general feel of my subject before I do more involved work.
I didn't ask her to masturbate, she just did. I had serious intent as I was making some preliminary studies for some print work. It took me by surprise. After a brief hesitation, I just kept on drawing. I thought it might be interesting to show action sketches, since I have complained several times about work being too posed and overworked.
