Background: Autofelletio is the act of performing fellatio on one's self.
The assisted autofelletio is achieved with the help of another person. As one person attempts autofelletio the second person pushes down on the shoulders in unison with the up and down motion of the first person.
The first person can use a free hand to increase stimulation during assisted autofelletio.
Bill: "Last night Jackie didn't want to give me a blow job but she helped me blow myself"
Rob: "You got her to give you assisted autofelletio?"
