Sexually suggestive hand motion simulating a handjob. You'll usually find three or four fingers bent in a circle or three fingers sticking out with the index finger and thumb together.
Should not be confused with fellatio gesture, as hand isn't in motion and tongue is usually visible due to open mouth and/or tongue out.
