When you blow your load in your partners ass, then stuff your fist up their ass and scrape the linings for the load (like when you carved a pumpkin). Take any shit and cum up there and put it in a bowl and make your partner eat it.

A cum-pumpkin is a large pumpkin with six holes so six guys can fuck and have cumgasms which they all eat afterward.
