cum dunk 

When a girl is giving a guy head and refuses to swallow, the man holds her head on his erect penis as if he was dunking her head into a pool of water. She now is left with two choices: drown or swallow. No, biting it off is not an option.

I wasn't even sure if courtney would be a swallower so I didn't take any chances. I gave that hoe the cum dunk.
