Head or Brain:
The performer opens their mouth and the male partner inserts his cock into the opening. The performer then proceeds to suck on the head or “tip” of said cock. Slang terms include, but are not limited to, “getting some head” or “getting some brain” (if you’re the performer it’s giving head or giving brain).

Most men loOove to get head (or brain) and i find this the easiest sex act to get done out in public (like a restroom, parked car or in a dark corner of a party or rave).
