On MUSHes, MUCKs, and other text-based role-playing games, players may list Fade To Black (often shortened to FTB) as a preference. This means that the player does not enjoy tinysex, and would rather end a scene at a suggestive moment rather than writing out everything their characters proceed to do pose by pose.
The scene is presumed to proceed offscreen. If they like, the players can pose the PC's waking up the next morning and working cricks out of their necks, rubbing the rope burns on their wrists, or making a hearty breakfast; all FTB means is that they don't have to spend hours typing out every single detail of how the characters got to that point if doing so would bore them or gross them out. In this sense, FTB is very much like fading to black in television programs and movies.
FTB preferences and policies can apply to scenes of graphic violence and horror as well as TS.
