Of course you do!

"Oh beast! Fill me! Fill me with your cum!" the princess exclaims.

Her moaning words push you to the brink of orgasm and you lower cock explodes with centaur cum. With your gigantic cock filling her pussy, there is no room for the huge amounts of cum that spray forth. At first, the cum begins to spray out of her pussy, around your cock but soon the pure volume of sperm causes the princess to be pushed off of your cock and onto the ground.

The princess rolls over to face up at you, her breasts exposed, her once tiny pussy stretched wide and flowing with your cum. She scoops up some of the cum with her fingers and then sucks them clean as she smiles at you.
