auto cum inflation

post #1504007 post #4426726 post #3147736 post #4541407

An off-shoot of the cum inflation fetish, in which a part of a character's body expands due to the amount of their own cum their body is holding, as opposed to a separate character's cum being the cause of the expansion as it is seen in regular cum inflation. This is most commonly caused by a character orgasming while performing autofellatio, but can be caused by other means of masturbation, sometimes including a character's use of portals.
