N.V.S.S.
N. V. S. S. is when you’re about to cum and you smash your face into your partner’s face and blast your cum straight up her nose like you’re trying to make her smell your sweaty sock.
I did N. V. S. S. in the car and my friend asked if I was trying to give the driver a headache.
I did N. V. S. S. at a restaurant and the waiter asked if I needed a napkin or a mop.
I did N. V. S. S. at school and my teacher sent me to the office like I was trying to start a fire.
