Leaving such a lovely wife alone, and moreover at my sister's wedding with many guests, is reckless. The sense of celebration, alcohol, and temptation would do the trick. The negro noticed the bored girl and was rewarded for his attention and concern for the beautiful stranger. She thanked him like the female the male had chosen for the day. Now her body will remember this unforgettable encounter.
Seems like the Asian man walks around day and night with only one thing in his head, how to talk his girlfriend into letting her cum in his mouth. That's why he came in his dreams - he didn't have the courage to do it in real life. And he got lucky!
