*DRAGON PR0N BE HERE* (AU/chan warning: Harry is 17-18 in this fic)
Harry's heart pounded as he slipped into the public lavatory. He glanced around. Seamus was right. The place smelled foul, it looked worse and --
There it was.
The hole in the lav wall was empty, but as Harry crept closer, he could swear he heard the sound of someone breathing on the other side of it.
"I'm hungry," he whispered, just as Seamus had instructed him to say.
The hole glowed a moment, then began to wander up the wall. It paused, sparkled golden and expanded in size.
Slowly, a prick emerged.
Harry's eyes widened. Bloody hell, it was big! Not long, thank God, but thick, with a bulbous, purple head already gleaming with pre-come. He licked his lips, crossed the sticky floor, and knelt.
He fell in love with the flavour even before he'd completed his first, tentative swipe of the head with his tongue. Immediately, he did his best to engulf the monster with his mouth, remembering to pull his lips around his teeth to protect the delectable flesh so trustingly displayed for him. He suckled, jerked, sucked, licked and nibbled until he thought he'd go crazy with lust. Pulling hard on his own cock, he opened his mouth to its widest and plunged onto the exposed penis until his nose hit the wall, and sucked hard.
He was rewarded by a flood of come, too much to swallow, especially since he was coming himself, harder than he'd ever come before, making sounds that would have embarrassed him with their neediness except that he could hear the same sounds coming from the other side of the wall. Face and hands painted with come, he slid down the wall, panting, as the lovely prick he'd just sucked withdrew and the hole in the wall glowed gold and once again froze in place.
He managed to clean himself a bit in the rusted water that dribbled out of the faucet in a half-hearted drool. He stuck his head out of the door to the lavatory and looked around. Seeing no one, he slipped out.
"Mr Potter."
Harry went utterly cold. Only one man spoke his name with such venom. He swallowed and prayed that he'd managed to clean himself up adequately.
"Fifty points and a week's detention for frequenting a known sexual trysting spot."
"I had to use the loo." He winced; the excuse sounded lame, even to himself.
"For the past twenty-three minutes? Perhaps I should ask the House Elves to incorporate more fiber into your diet."
His face flamed. "May I be excused? Sir?"
"Report to me tonight at eight o'clock sharp."
Nodding once, Harry walked away, feeling Snape's gaze boring into his back until he rounded the corner. As soon as he was out of sight, he ran as hard as he could.
Still, he reflected as he slipped back into the castle, it had been worth the points and the detention to have blown such a lovely cock. He could understand Seamus's obsession with the act. Next time, he'd just have to plan better, that's all. Maybe he could learn a warning Charm that he could use...
****
Snape watched Potter walk down the hall, his arrogant head held high even with a flaming face. He smiled to himself when the footfalls turned into the sound of someone running for his life once Potter rounded the corner.
He adjusted his prick. He'd gotten half-hard again while watching Potter's panicked and pathetic attempt to excuse himself. Obviously, the episode had been Potter's first attempt. Still, the boy's mouth had been sweet, his excitement gratifying. Much better than the Finnegan brat's.
Remarkable, really, the amount of joy a man could derive from a simple patrol. Smirking, he followed Potter. The detentions should be - delectable. He wondered how many times he could work 'hole' and 'wall' into his conversation tonight, and imagined Potter's aroused squirming. Yes, he thought.
