"Give me those, Severus! You know I can't see a thing without them!" Harry sounded almost panicked. 'A pity you can't see me smiling at you, then." Snape replied in his indolent drawl. He drew a line across Harry's chest with the hornrims, plucking the nipple as he drew across it. "Oww!" Harry squirmed, at batted at his lover. Snape grabbed the offending hand and pinned it to the wall. Harry struggled, but only a bit. He threw back his head, exposing his throat.
Snape growled and bit, feeling like such a predator. "Don't you dare break those, Severus." Harry murmurred, as the sharp teeth grazed his collarbones.
