Sometimes Bad is Good

Before he knew it, Harry was having to force himself not to shudder, either in pleasure or revulsion he didn't know although he was more than willing to bet that it was revulsion, as Malfoy leaned his slightly pointy chin on the top of his rapidly rising and falling shoulder and brought his mouth so close to the side his head, that Harry swore he could feel the fluttering of those surprisingly soft lips barely brushing the shell of his ear.

"What's wrong, Potter?" Malfoy whispered, catching Harry off guard with how breathless and excited his voice was. "Vampire got your tongue?"

And then he licked a tentative and long, fire-hot trail up the outer shell of Harry's ear with the tip of his searing wet tongue.

(Or, in other words, Harry is a unique and highly rare submissive creature/being and Draco is his dominant vampire mate. Enjoy!)
