Ciel may be naive when it came to romance, but he had seen enough of the steamy romance movies his mother (and his father, though Vincent would never admit it) liked to watch. This was a scene meant for two adults to have sex.

Ciel was neither an adult, nor particularly interested in sex, unlike many of his peers who were beginning to learn what their dick was for. Why the creature had done this he had no idea. Surely it wasn’t interested in him that way, right?
