Nasal Squirrel
A nasal squirrel is when a male is getting a blowjob from his partener while he/she is upside down. At the climax of the blowjob (during the ejaculation) the male attempts to seperate his balls and place them in his parteners nose, one in each nostril. This gives a tingling sensation to the testicals.
My friend reccomended me to try the nasal squirrel so I did.
