Never - never - never had a woman pressed herself against him in this manner! And although it was a part of a dance, and although he knew that his kitten was a dramatic one, he could not convince his body that its reaction was foolish and should be stopped. His mind knew better; she was not the one for whom his desire flared. But despite the years of living as a creature reviled by humanity, Erik was indeed still just a man with a man's cravings and a man's responses. When he finally closed his arms around her, when he finally seized her wrists and held them tight against her chest, his grip was harsher than he'd meant.
He knew it, too. Enigma may not have understood fully, but Erik did. A moment later, he was relieved to fling her far from his body, if only to give himself a momentary respite from the unfamiliar responses. It reminded him too much of the odalisque who had been gifted to him in Persia -- the same young girl who preferred to die than to share a bed with him for a single night. And die she did...screaming and terrified and bloodied, she died.
The memory effectively killed his reaction. He was not so pleased as he would have first guessed he might be.
