"The Cumcium" is when you fill a turkey baster with milk, and insert into a woman's vagina, squeezing out the contents. Then the male proceeds to cover his erect penis with chocolate syrup. Next, the man has intercourse with the woman, thus mixing the milk and syrup. Then, as a treat, the man ejaculates into the woman. The woman then squirts out the chocolate milk-cum into a cup. Finally, the two drink it together. It's chocolate milk with a hint of sperm!!
Henry and Diana love to perform the cumcium every school night.
