The beginnings of an obsession

A week past until Harry had a real chance to get close to his Professor, in potions today they are making a..potion surprisingly enough. Everyone came in, sat down, Snape’s entrance, few instructions and off they went.
Harry’s partner was Ron, they both got quickly to work cutting and slicing their materials.
“Harry can you cut the bat tongue?” Ron asked squeamishly.
“Give it here” Sighed Harry.
Professor Snape was wondering around the room glaring at all his young students and picking on all the minor details * Oh no that girl’s potion is the tiniest bit lighter blue than is recommended*.
“Potter concentrate on your work” Snape said to Harry who had been staring over at the light blue potion.
“Oh sorry Sir” Harry turned around and acting with his cock not his head he ‘accidentally’ spilt all of the goat’s stomach acid into the potion, smoke filled the whole classroom which made everyone have a coughing fit. The potion master wasn’t happy, he reached into his pocket and pulled out his wand.
His spell cleared the room up instantly and left guilty looking Harry by himself at the cauldron that had made the mess. * Detention detention that deserves a detention*
“Potter! Detention!” Snape yelled.
* Yes! * Harry sighed then nodded pretending to be upset.

After dinner Harry set off to the dungeons where his big sexy Professor will be waiting to take him..to the sink to wash some dirty jars and things. Harry knocked on his chamber several times and entered when he heard Snape tell him to.
“Ok Potter seeing as you made such a mess of my classroom because you seem incapable to follow my instructions, I will have to make them a little easier for you, go over there to the sink” Snape pointed to a old little sink in the corner “See the empty bottles and Jars right next to it, wash them” He sighed then sat back down in his chair to finish marking.
There was a huge pile of bottles and jars piled up next to the sink because there was so many it looked like Snape had gone to extra trouble finding more for him to clean.
After about an hour of scrubbing Harry put down this washcloth and turned to face Snape. He was hunched over his desk, pen in his hand writing away. Harry smiled.
“Um..Professor?” Harry called.
Snape looked up and saw Harry looking very tried and the pile of bottles and jar considerably smaller, his big green eyes seemed to be begging for something but mostly likely not what Snape was hoping for.
“What is it?” Snape asked.
“Can I take a quick break, I’m so worn out” Harry said.
Snape was right, it wasn’t what he was hoping for.
“Yes alright but not for long” Snape said.
* Also would you like to put your dick in my ass? *
Harry sat down in a chair at Snape’s desk, crossing his legs because he was getting hard again. Being this close to Snape he just can’t help himself, that man is too delicious.
Little did Harry notice, Snape too had crossed his legs. Snape may hate Harry’s father but the thought of fucking his son was a huge turn on. Harry had grown since he’d come to Hogwarts he now had broad shoulders, a nice firm body from all the Quidditch, was quite a lot taller and those eyes, his beautiful big green eyes.

“Sir?”
Professor Snape had just realised he’d been staring at Harry for several moments with a look of lust upon his face.
“Thats long enough, get back to work” Snape snapped trying to hide his embarrassment.
* That look he gave me…he wants me too I know it*
Harry stood but didn’t go back to work, instead he sat up on the desk and leant over so he was inches away from Snape.
“Are you sure there isn’t something else you’d like me to do?” Harry whispered.
“Potter what on earth are you doi..” Snape didn’t get to finish his sentence because his mouth was pushed up into Harry’s. Harry kissed Snape’s lips then struggled to get his tongue into his Professor’s mouth, when Snape couldn’t take it anymore he allowed Harry’s entry. Their tongues danced together in each other’s mouth for a while before Snape pulled away.
“Harr..Potter I think.." Snape gasped " this shocking behaviour deserves another detention"
“Good” Harry grinned.
