He shakes his head, slowly, as if he was denying a candy from a kid, in that gentle manner. "Spare you...?" His smile becomes wider, so sweet, so luring... "Not exactly..." His voice coming out with his breath, and he leans forward, admiring his prey in such tender way it'd be impossible to tell he was killing him.
"I just want to see the light disappear from your eyes when I have you all from my own..." His lips were so close to his other that they could almost brush lightly. Shadow didn't know much of what he was doing, just that he wanted to drink all of him, and that nothing would give him more satisfaction that taking his life for his own. Mephiles' dim breath mixing with his own was driving him a bit crazy, too bad it had to end...
Once again, he bit him, but not in the same place as before, but in his lower lip, and this time it didn't have the same strength, for he was being tender and carefully treated. He never took his eyes away from those serpentine ones, he didn't even blink. And he began drinking again.
