I'm writing a story in which two of a woman's friends help her get revenge against her cheating boyfriend and his lover. Now that I've reached the big revenge scene, I'm having difficulties writing a scene that has five characters in it.

During the scene, the main character is tormenting her boyfriend, who is handcuffed to the bed, while her two friends work on the gagged girl. It helps that both of the prisoners are gagged, but I'm still having difficulties managing the scene.

Any advice for keeping the scene exciting? Should I frequently cut back and forth between the two victims, or should I tell most of one thread before jumping back chronologically and describing the other half?
