Surprised but not deterred.

The man's cock bumping your nose startles you, causing you to fall backwards onto your ass.

Amidst the tension you are feeling at the entire situation, you are suddenly struck by the absurdity of your current predicament.

Muttering a soft prayer, you close your eyes and lean forward again. When you feel the cockhead brush your cheek, you correct your aim, bringing it to your lips. Without further encouragement, you open your lips in a big "O," taking the tip of his cock into your mouth. With your lips wrapped around his crown, your tongue moves tentatively, to lubricate the vile intruder you reason, but secretly, a part of you just wants to taste the man's cock.
