Hey Stewart, remember that loud drunk bitch at the party last night?
Well, I went fishing with that ho and I caught the largest cum mouth bass ever.

mouth-cum is the blob of jizz that a guy can get when he's jacking off and part of his cumshot splurts in his opened mouth.
I wanted to taste my own cum, so I put my heels on the wall and jacked off so that when I blew my load - - I'd get a good amount of mouth-cum to swallow!
