When a man who is right hand dominate masturbates with his right hand to ejaculate into his left hand. He then uses the ejaculate as lubrication to masturbate a second time with his left hand.

I downloaded this awesome donkey porn last night and I had to use a left handed screwdriver to finish watching it.
