Smell-Check 

A check done by men during foreplay to see if a chick is clean enough to eat out. The guy fingers the chick's pussy and then he gets his fingers back into range of his nose to sniff without the chick noticing. It is easily done behind her back while kissing the side of her neck

Porn stars do not do the Smell-Check; 'Regualr' guys do.

"Yes."
