eve's plan

Phobe, Prue and Piper were working on a spell

It been a long day vanquish demons and fighting the good fight while trying to hold on to some sense of a social life. They were dressed in tight clothes. There wore leather pants and belly shirts. Their bodies were dripping with sweat from working on the spell.

Uknown to them Faith watch. She had waited a little bit for her power to get back up. A day feeding magic from an occasin demon that wander in San Fransico. Now she had her eyes on them

She had plenty in her Harem to stop them. Plenty of good little soldier but these witches were powerfull. If she wanted to sapped thier power she may have to take them one at a time but how.

Which one?
