Popping corks.

As Jess was blowing me, I leaned back and sighed contentedly. "Man. I have the best girlfriend. I can't believe she's okay with this."
Jess made a popping sound as she took my cock out. "Well, I guess she figured you deserve it, you know?" She gave me a look. "For what you're putting up with."
I looked down at her bobbing head. "What do you mean?"
Jess gave me a puzzled look, rubbing my balls. "You know...." suddenly her eyes went wide. And then she gave a little smile, and a little shake of her head. She said something under her breath, sounded like "...don't know..."
"What was that?"
"I mean, putting up with her flaunting herself in front of your friends. I know that she asked you if you thought they would fuck her."
"Well, I mean... I had to tell the truth, right? She's a fine piece of ass and she loves me. Of course my guys friends would try, but I trust her." Truth be told, I was worried a little, but my angel was mine. I knew it.
"Stand up, John." Jess grabbed her phone and started jerking me fast. "Time to pop this cork."
With one hand, she expertly pleasured my cock while typing with the other. "Wha...oh fuck...What are you doing?"
"Letting them know we're almost done. And I want something to remember this by." She smiled, and I tipped over the edge. Shooting a big rope of white cum in the air that landed square on her face, from forehead straight down to her chin.

Jess laughed as a second and third rope hit her face. "Good boy. Such a good boy. Thank you, John."
Once I was finished, she took a selfie. "A little souvenir for me..." she stood up and kissed my cheek, leaving a smear of my own cum on my face. "I'm going to wash off."
