pig heart 

When you half-wrap your cock under your ball skin and pop one ball out the side to make it look like a fat vein and chamber and proceed to squeeze it underneath to make it beat like a pig's heart

Your mom said she loved pork so I showed her my pig heart

Laura: Ugg Who cares she will always be a PIG AT HEART!
