OP, you were making a mountain out of a molehill.
Your reaction would have been justified if she refused sex with you the night before too. But, according to your own words, she gave you great sex, she even got so wet you had to change sheets midway. She was submissive, femine, and into you the entire night (assumingly). And what did you do? You "purnished" her GOOD BEHAVIOUR by doing what you did.
It's OK for some girls to not like morning sex, because morning is when they normally wear makeup, get dressed, and ready to go out, that's why it's TOTALLY normal and healthy for some women to not want to have morning sex with you. Not everything must happen like that porn scene, you know?
You should have kept your cool, and offered to have some nice breakfast with her. After all you're the man, but you were acting like a spoiled child throwing a tantrum because he couldn't pursuade his parents to buy him that shiny toy at the store. Come on man!
