Always vocal, Lara was moaning and writhing on top of Ella, and showing her appreciation as her tendril of power explored. At least until she felt Ella's nails on her behind, which was enough to drive her over the edge and she came screaming with the force of the orgasm being just enough to break her control and make the tendril vanish.

Of course when she was able to think again she'd realise that it meant that Ella had broken her bonds; there would be no relief for the vampire in the near future.
