Multiplicity

[Sonia]

So your fuckin this chick, right? And youve been with her a few times, so you say, you know what really turns me on? Sex by a window. And shes like, okay.
So you start fuckin her from behind so shes looking out the window, and you [slip out] a few times, but its cool, because you [get right] back in each time. Then in a closet or somewhere, you got a friend erect and all ready to go. So he comes up right beside you and when you slip out this time he slides right in, and she doesnt notice that [its not you]. You quietly leave the room and run outside, infront of the the window and walk away; make sure the bitch sees you though.

Also known as [Multiple Systems]; Related to Otherkin: People who describe themselves as [multiple systems] (also known as multiples, multiplicity, plurals, alts, and many other names) take the idea of headmates one step further by believing that they actually have multiple people who make up their multiple personalities. So a person who describes themselves as a multiple system will likely refer to themselves as they because they believe they are multiple people. When they are acting as the personality of one of their headmates, they call this fronting.
Some multiple systems will have headmates who are animals, otherkin people, and, of course, fictional characters. There are also people who believe they have galaxies, nebulae, universes, and other [space shit], either in their headspace or as an otherkin. So some people will believe they are actually galaxies.
