Have sex with Sildoria?

[MexiCali]

I have not been able to finish the intimacy battle in a dungeon with Sildoria. At present, I have 675 points in skill and 1800 EP.
Unfortunately in the first play though, the nun is missing so I cannot change my stats around. Since I have not yet slept with her, letting her burn through my EP only ends the encounter. Most of the time though, her arousal is maxed and it ends the encounter.
Is there a good way to raise her anxiety faster than arousal? Specific equipment, affection levels, patterns of seduction?
Thanks in advance.

Seems I needed to bed Kushina first. Then it worked first try.
