The newspaper is taken and rolled up to resemble a funnel, which is then placed into the woman's upward facing vagina.
The man now adds the cake ingrdients to the funnel and mixes vigorously. When the mix is ready it is poured into a bowl with any that happened to enter into the woman. The mixture is then either eaten raw by the couple or baked and presented to unwitting friends and family members.
Warning: Can lead to intervention of social services and/or severe yeast infections.
