Pulching means: Fisting is the sexual act of fisting your anus until you have a wide enough opening for you to add the three main ingredients to trifle. You can make jam, custard or sponge. After committing to anal sex, the “pulcher” then makes the “pulchee” eat the mixture. After excretion, the ‘pulchers’ consume the mixture via a combination felching and excretion.
