When two or more unwilling individuals are forced to participate in sexual acts with each other. 
This might be because of being [[bound together]] by restraints, being coerced, or because of being under (apparent) duress, such as being held [[at gunpoint]] or other [[threat]]s.

If any (but not all) of the participants [i]are[/i] willing, you should probably use the [[rape]] tag instead.
Avoid using this tag when the participants are merely under [[hypnosis]] or [[mind control]], unless their powerless "inner selves" are also portrayed witnessing the scene.
