Enslaved by the Wolves

This is a choice I never wanted to make... I've never had a sense of purpose until now. I have my brother's three sons to raise. I vow to give them the childhood I never had. When Lucas and Kristoff claim me, I am helpless. The lust in their eyes gives me another purpose. A purpose to please them. They terrify me, but at the same time thrill me. Our passion is more than anything I've experienced before. But I can see danger lurking in their eyes. Something is coming to harm us. To harm the boys I've vowed to protect. Can I stop this dark force? Or will it mean severing the only bonds of family I have left?
