   Summary

   “Would you bend over Father’s desk for me, I wonder?”

   My desk, Ciel thinks childishly, even as he gets wetter at his brother’s taunting. Everything in this bloody house belongs to me. Including you…especially you.

   “Would you beg for more when I was done?” Then that silver tongue flicks at his left nipple, his brother taking it into his mouth and inflicting a vicious bite.

   Ciel’s spine bows, his fingers twisting into storm-colored locks. “Nuh—oh!”

   “Liar.” He laps at the blood beading around Ciel’s areola, his moan guttural. “I hear you most nights. You and that dog. When you scream for him. When he makes you hurt. Will you sound just as sweet for me, baby brother?”

   Or: The twins learn how to cohabitate after years apart...one disagreement at a time.
