Having sexual intercourse while having the female bent over the counter making a sandwich for the male counterpart. Sandwiches may vary in complexity from ham and cheese to a full blown BLT (frying of bacon included). The product sandwich may then be enjoyed by the man either instantly or to be stored away for a later consumption. (Packed lunches, etc.) In addition, if the cutting of meats such as salami is required, the female may choose to hold the meat steady with one hand and allow the thrusts to power the slicing of the knife.
