"I's really the rest of me that's the weak spot, here. I mean, I can go on for a long time, and this thing doesn't seem to get tired, but... the rest of me is only human, so eventually I'll be too tired." She smiled happily. "I'm willing to give it my all, of course. Anything my beautiful princess desires, even if it means you have to summon help to carry me out when we are finished."
