Cumflation
Cumflation, also known as cum inflation, is a fantasy fetish that involves a bottom taking in so much cum that they begin to inflate. The fetish generally centers around anal, vaginal, or oral sex, but sometimes includes the urethra, nose, or navel.
Because actual cumflation isn't physically possible, this term is most often used in pornography and hentai.
Origins of the Term
Cumflation appears to have developed within online body inflation communities during the early 2000s. Stories tagged as "cumflation" on the site bodyinflation.org data back as far as 2003, suggest the fantasy existed by this time.
By 2010, the term cumflation was being used more widely, and was entered into Urban Dictionary. Google Search data suggests the term gained wider traction in 2012, and that online searches for the term continue to grow.
Cumflation became and established hentai tag in 2019.
