shooting a shit ton of jiz into your partner's fun hole and filling them up until they either look pregnant or can't hole anymore of your jiz. this act is almost impossible due to the fact that a man cant produce enough to fill up their partner that much :L

The act of injecting ludicrous quantities of spooge (usually greatly exceeding the volume of one's own body) into a receptive sexual partner, causing their entire body to swell up like a balloon. It is a combination of sorts of hyper and inflatophilia. Usually seen in furry or other types of cartoon porn as doing this in real life would prove excessively difficult, regardless of one's confidence in his own manliness.
Don't you try to force your disgusting babyfur fetish on me! You know I'm only into perfectly normal, realistic cumflation scenes!
