To Nasonex a girl. While receiving a blow job or having sex and you are about to nut, you release your jizz into one of her nostrils while holding close the opposite one.
I nasonexed my girl last night and now she has a sinus infection.
When one (man) is recieving oral sex from one (woman/man.) The reciever will then take his (penis) out of the oriphice of the giver and (ejaculate) in the giver's nose.
My girlfriend had a sinus infection, so i gave her a shot of nasonex and she felt much better, but she smelled like burntsalt.....and cum.
After receiving a blow job, holding a girl's mouth closed and blasting your cum up one nostril. Optional to make the Antonio Banderas bee voice while you're doing it.
