Since she was an elf, Kara would have a lot to give to the two demons, and so wouldn't have to worry about becoming weak for a very long time yet.  Being tired on the other hand would be something she'd be having to deal with for a few hours as Jacob gasped, putting his hands to her head to keep her there as he finally released his load deep into Kara's throat.  Women had been known to become addicted to his cum, Jacob knew from past experience.  Their bodies wouldn't take normal food without his seed to keep them satisfied after he had had his way with them after a long enough time.  One helping would at least stir up that particular hunger as he emptied his seed into Kara's willing mouth.  Yes, they would have to keep her around so that she would help rule over the mortal races of this pathetic world.<br/><br/>Kirith started fisting the girl, sliding her whole hand into Kara's body.  The taste of her soul, dark and yet rich at the same time.  The heat of the mage's fire powers was infusing the demons with a strength they hadn't known before as they started to glow a deep red, a fire glyph appearing on their stomachs as Kirith smiled.  "Come my pet.  Come and be our slave as long as you serve us faithfully!  The rewards heaped upon you will be grand indeed!."
