The female version of a blowjob, giving oral sex to a female.
She never got off from sex, but she did get off when he gave her a clamjob. His clamjob technique was first rate.

Applying salt to the area surrounding your asshole and then having a clam lick it all off.
Dude, sorry I couldn't pick up the phone. I was getting a clamjob.
