Well you still can't force her to be submissive, unless she really wants to try.

I am a "wham, bam, thank you m'am" kind of girl.
I don't mind foreplay, but most of the times, I want an orgasm within the first five minutes, and then I'm satisfied, screw whatever the other person wants.
But I can be in situations where I can have that orgasm denied and prolonged.

Have you both seriously sat down and discussed this?
You could broach the subject with her and ask if the next time you are together, that you would like to try a longer drawn out foreplay, and not to give in to her need to have what she wants now.
You could tie her down with scarves, and tease her for awhile.
Start off slow, with small time frames and gauge how much she enjoys it.
After the fact, discuss what you and your partner enjoyed or did not enjoy and continue on from there.
