The succubus smiled as Niarra took the potion.  "Good girl.. I'll be back," she said as she stepped out of the cell again.  She left for a moment, going to a small trunk sitting just outside of the cells, and taking out a metal rod.  It was about a foot in length, with a wooden handle on one end, and a vaguely heart-shaped design on the other, resembling a branding iron.  She smiled at Lyla, entering her cell, and holding the iron above her.  "Lie on your back and hold still, dear," she said, once more enchanting her orders, as she leaned down to place the pattern over Lyla's belly, directly over where the markings in her virgin blood were made.<br/><br/>Immediately, magic sparked out of the device, and Lyla instantly felt incredibly aroused.  The sensation lasted for only a moment, then faded away again, leaving her exhausted from the spell.  When the succubus removed the iron, a pink stylized heart design was left on Lyla's belly, the mark practically humming with magical energy.  "Now, you are mine, girl.  For as long as that mark remains on you... and it will remain for quite some time," she said with a smile.  "Please me, and you may come to think of it as a gift."
