The Irish Igloo
You begin by cutting a hole through the center of a potato. Following the excavation, you allow the potato to freeze in the wilderness (under no circumstances use a freezer). Once the potato has solidified, insert gravy into the cavity that you have created. Finalizing the work, force your cock into the potato until you have reached a point of ejaculation.
The boys were feeling a little frisky one night and decided to get The Irish Igloo going until everyone used a potato to finish.
