There was one thought that Ciel would never allow himself even a moment to contemplate. Only one feeling that he would continue to deny himself. For to do so would mean losing his revenge and his life. He couldn't allow himself to slip even for a second or Sebastian would turn on him instantly. Demons knew nothing of loyalty, and especially of love. Sure they loved exploit both for their benefit but they would never understand either. Ciel did and that was why he had to bury all the unnecessary emotions, the intruding thoughts under a screen of lust. Because demons understood the ecstasy of intertwined bodies and it was the only time he could truly forget what he was forbidden to think about.
