I am wondering. In other writers opinions what is the ideal number of people one can add into a sex scene and it not feel to jumbled or confusing for a reader. I kind of like four myself. Me personally three seems like you always have someone who isn't getting fucked but it can lead to more intimacy in the scene. With four you can end up with really just two people fucking while the other two or fucking and there is no interaction. Just curious on other peoples thoughts.
A gangbang can have multiple people but have one MC. It could be the whole city debauchery survivor style type. If characters had prior development, you could still have, let's say seven on the bed. odds and even just opens up a new possibility. anyways that's just how I imagine it.
IMHO, scenes with multiple people are more WORK, both in RL and in fiction. Organization seems to help in both. However that's accomplished is up to the individual author. Some folks narrow it down to one character's perspective, which makes the larger scenes more understandable because you're only seeing one perspective. Others TRY to cover everyone's thoughts and actions, but that is a hell of a lot of work. I don't think I'd ever try to write above Six participants. That's my personal limit. While that makes it officially an "Orgy" I don't think I could keep track of too many more thoughts, emotions, turn ons, turn offs, and general needs in bed. Hell, above three and you're already getting into the embarrassing situation of mistakenly calling the wrong name in orgasm...
I've done a few in Lois Lane's Night Out. So far, this has mostly been threesomes or a general orgy situation. For the threesome, it's important to know where everybody is and what they're doing - even if the focus is only on the interaction of only two people at a time, the third one is still there and participating in some way - even if it's only slowly masturbating as they watch the other two have a moment. Readers, I think, like the spectacle but also the sensory overload of people interacting together. Three people just opens up more possibilities as far as available holes, hands, mouths, etc. - but it also opens up considerations of complex emotions, and just how to get everybody together, and how they affect each other (remember each of those bodies has mass and inertia!) More than anything, threesomes are generally about exploration, showcasing the different positions and possibilities which those involved with might never have experienced before - and which the reader can experience vicariously through them. The general orgy scenes, for me, always involve a single character as the point of focus. Usually, I go for a sense of overwhelming sensation; there are just too many people for the individual to focus on or control at once, and so they end up almost in a public use kind of scenario - and it's the letting go as much as the individual positions and maneuvers of the fucking which is the mental stimulation for that kind of scene. Hands emerge from nowhere to grasp, fondle, and grab; fingers, toes, tongues, and cocks prod and poke, taste and tickle; but it's all about the perspective of what the individual is doing and what is being done to them. However, I feel there's often a limit to such human mating balls, and the scenes usually break off in either some kind of mini-climax and/or with an individual or individuals breaking away from the main group for a piece.
