Harry was leaning heavily against the castle wall in a rarely traveled corridor at Hogwarts school of Witchcraft and Wizardry.
This, in and of itself, was not all that unusual, as Harry was in fact a 7th year student at that prestigious educational establishment and if truth be told he did have something of a reputation for exploring the multitude of unused rooms and seemingly long abandoned corridors of Hogwarts Castle. He, along with his two greatest friends, had already had so many exciting adventures and many were had right here, in the dusty and poorly lit corridors of Hogwarts.
In fact Harry's very first adventure here had to do with the "out of bounds to all those that do not wish to die a horrible death" third floor corridor wherein He, Ron and Hermione ran afoul of a gigantic three headed Cerberus with the unlikely name of "Fluffy" in their quest to find and protect the Sorcerers Stone.
So no, Harry being in a dust filled corridor somewhere in the uncharted depths of Hogwarts was not at all unusual.
However, having his closest friend push him against the wall and drop to her knees while she pulled his cock from his trousers and attempted to deep throat his John Henry like some demented side show sword swallower, all without the slightest of explanations for her behavior, would definitely qualify as somewhat out of place.
Even Harry Potter, the "Boy Who Lived", Vanquisher of Lord Voldemort, Defeater of Trolls and Dementors and Friend to all manner of Magical Creatures found her actions to be highly unusual...fucking brilliant...but still, highly unusual.
"Eh, Hermione?" Harry stammered, "While I'm certainly not complaining, in fact let me be the first to go on record as saying 'oh God that feels good', it's just that I'm wondering what brilliant, noble or heroic thing I might have done to deserve such incredible treatment? Because, if this is some kind of reward for some action of mine, I really want to know what it was...so I can do it again...as often as possible."
While Harry was babbling, as all teenage boys are wont to do when they find themselves being well and truly 'sucked off', Hermione, with the greater portion of Harry's cock still firmly lodged in her mouth simply looked up and made eye contact with the young man receiving her ministrations and having garnered his undivided attention simply smiled and went straight back to her oral and lingual explorations of the truly tremendous 'boner' belonging to the young man she had decided to make hers, body and soul.
And even Hermione, Hogwarts brightest academic light and self avowed ' bookworm' knew that the old saying that 'the way to man's heart is through his stomach' was utter rubbish, and that the fastest way to a man's 'heart' was actually straight through the end of his dick.
As Hermione continued to bob her head up and down on Harry's cock Harry was rethinking his entire attitude with regards to the lovely,and apparently quite talented, Miss Hermione Granger. For years she had been at his side and through the good times and the bad times she had been his rock. His safe harbor in the perfect storm that had been his life ever since Hagrid had kick down the door of that small shack on the island that his Uncle Vernon had taken shelter in to avoid the barrage of letters from Hogwarts intended for Harry.
Hermione was not just one of his closest friends, she was in fact Harry's best friend. Ever since the nightmare that had been his fourth year she had replaced Ron Weasely as his 'best' friend as it was she that had steadfastly stood by him and believed him when he said he did not enter himself into the Tri-Wizard Tournament whereas Ron had refused to believe his claims and had gone so far as to accuse him of being a 'glory hound' and berated him for not including Ron on his newest 'adventure'.
While Harry's mind was lost in thought his body was urgently attempting to secure his prick even further in Hermione's throat. Harry's was pulled from his remembrances when he felt that tell tale tingling in his balls that he new indicated he was about to blow and being the gentleman that he was he felt it only fair to warn Hermione of that impending fact.
"Uh Hermione...?!" Harry gasped.."if you keep that up I won't be able to hold back!"
Hermione once again met Harry's eyes and increased her sucking and slurping in what Harry took as a clear indicator that she was ready and willing to have him release in her mouth.
So he did.
