Surprise her by pulling out and jerking off on her face
From Create Your Own Story
As Kara continues to bob up and down on your cock, you feel a cumshot building up inside you that you know you won't be able to hold back.
At the last possible instant, you pull your cock out of her mouth. With one hand, you grab Kara's hair so she can't move her head, then jerk your cock with the other. Surprise fills Kara's face- she has time to get out a quick "What..." before your first spurt of cum makes a line across her mouth and nose. You stroke yourself in time with your cumshots, coating Kara's face with hot, white semen, until you are spent and your cock hangs limp. You came buckets. Kara's face is screwed up, glazed like a donut, her eyes closed tight.
"Why did you do that?" she demands.
