Cum Inflation 

Cum inflation is when a male/female (mostly in fiction) are ejaculated into in such great volume that their stomachs start to distend/expand. This can be done orally, vaginal, or anal.

This tends to happen mostly in hentai and furry pornography due to it's impossibility in real life. It is also common that the person's breasts and buttocks start to swell (inflate) with semen as well. This is due to the highly fetishised nature of the subject matter.

"Hay tomson! Do you see this crazy picture that I've found on the internet, it looks like a Fox man with a huge penis is cumming into a huge pregnant girl!"

"She's not pregnant, it is a Cum Inflation picture!"
