Cum has a few definitions - it could be a man's ejaculate, a female's vaginal liquids, or, the act of orgasming. Cum is a warm, thick, milky substance that tastes different depending on what you eat.

For instance, if you ate watermelon prior to a blowjob, it would taste really sweet, but if you drunk some vodka, look out.

1) Ah, yes... I am cumming...
2) He then squirted his load of cum right down my mouth
