The person in the middle of a threesome penetrating a person and being penetrated by another person.

The first person must receive, the second gives and receives, and the third only gives. To be a real dongle, there must be penetration with either a strap-on or penis.
Kevin didn't have a good time being the dongle last night when he didn't finish in sync with the others.
