The sneaky Martineau

While having sex with a woman doggy-style, you, as quickly as possible, sneak your pinky into her asshole. At the same time, you reach forward and bat your hand over her mouth so she makes Ojibwa Indian noises. Practice makes perfect, repeat every time until you get the desired effect which is making her yelp out of suprise and pain at your finger in her ass, then the covering and uncovering of her mouth will create a sound not unlike an Ojibwe Indian way cry
