When your girl is on her knees in the hot shower ready to suck you off, and you stretch your nutsack out into the shape of a bowl to catch water inside it. Once full, you dump the holy water on her head to let her know she has been blessed to swallow your unwanted children.
Its time for your 7pm baptism. Get the shower hot so there is more room for the holy water...
When she's on her knees in the shower and ready to get the dick in her mouth, you stretch your sack out into the shape of a bowl and fill it up with water. Then you dump that holy water on that bitches head to let her know she is blessed enough to gargle your unwanted children.
That bitch wanted to choke down the pole in the shower, so I had to give her a baptism to suck down on this communion.
