I prefer to lay on my back to get licked. If I kneel and straddle his face, when the feeling's too intense I can't hold myself up. When I'm on my back I like to take both of my hands and pull the hair/skin of my pubic area tight (up toward my belly) so that the head of my clit is as exposed as possible-I like to hold my head up and look at the connection of his tongue with the head of my clit until the feeling's too strong and I have to throw my head down on the pillow and close my eyes.
