The Flaming Lipton

This procedure is performed by a male and female couple, the only feminine requirement being unusually large labia (or 'Mud Flaps' for a better visual). Prior to engaging in a female-on-top '69', the female sprinkles copious amounts of her favorite habanero sauce on the 'Mud Flaps'. As soon as the Male engages the 'Mud Flaps' with his mouth, she presses into him and locks her knees around him, holding on for dear life.
If the female is feeling paticularly spiteful, she can dust the inside of her sphincter with chili powder and fart or 'tear gassing.'
The unusually large labia requirement is keeping with the spirit of the definition, i.e. 'Lipton' implies teabagging and large labia would be a prerequisite for female teabagging. The requirement is not necessary for performance of this act.
