When you let a nose-pierced fatty suck your cock and just before you blow your load, you shove your dick up to the whore's nose hole and let loose. Then you watch as the sperm shoots out the whale's blow hole.
My fat neighbor kept on beggin' for some vitamin D and I hadn't nutted for quite some time, so I let the whale go down on Moby Dick. I filled the beasts nasal cavity with so much baby gravy, it shot out the whale's piercing hole and stained my rug! A new species of Sperm Whale has been discovered!....true story.
