Harry ran into his professor's office, he was about to be late to his career meeting. He shook his head as he busted through the door only to see his professor behind her desk drinking from a glass of wine.

"Oh" Harry took several deep breaths "Professor, sorry for being late, Ron and Hermione held me up with these stupid questions about house elves" he said as he sat down in front of the woman, also that was a lie.

He was late because he was trying and nearly did get into Daphne Greengrass knickers, he completely forgot about this meeting and had to rush over. He switched his focus over to his professor quickly after she cleared her throat.

Professor Mcgonagall stood about 5'5" tall. She was in quite good physical shape, likely from regular exercise and being an avid quidditch fan. Her eyes were bright and sharp, and her face was slender with strong cheekbones and full lips. She had long legs, though she was not busty. Her hips however had some real curves to them.

She was wearing a long skirt and revealed her shins. She had the typical professor robes on which left much to the imagination.

"Mr Potter" Her sharp voice but a pause on his wandering eyes "If you could not stare at my legs and instead show up on time, that would be kind" Harry blushed slightly in embarrassment and nodded in response to her statement.

"Now we are her because you want to be an Auror, now, I need to ask a few questions" she paused and let Harry absorb her words before starting again "As you know an Auror has a lot of power, so to any aspiring Auror in school we need to ask them a few questions, very simple stuff" McGonagall said with a stern look on her face.

Harry was listening but was bored, he was thinking about what he could be doing with Daphne right now and regretting coming here. His daydreams were interrupted by a cough, he looked up towards his professor quickly and blushed once more in admonishment.

"Sorry Professor" he said while averting his eyes.

"Now Potter, first question. Why are you becoming an Auror" she asked bluntly while having a notepad at the ready with a quill held tightly in her nimble fingers.

"Well why else?" He asked without expecting an answer "I want to save pretty witches like yourself professor" he said with a teasing grin.

McGonagall was not impressed "Potter be serious, these notes will go to your future boss" she said while shaking her head. "You're too much like your father at times."

Harry grinned even more at that, he loved being compared to his father. "Mr Potter you could do better following your Mothers example" she said with a sigh "Now what are your favourite spells?"

"Well I would say my favourite would have to be Ducatus professor" he asked with a grin not expecting his professor to know the not known spell.

"Really Potter…the lubricant spell?" She asked, now she was thoroughly annoyed.

However Harry was simply shocked, the Ducatus spell is an offshoot to an offshoot to the main Lubricant spell, which means she knew one of the least known lubricant spells, which also means she probably has searched for it purposely…and given this version of the spell was invented 8 years ago meant it was recently Harry's mind was spinning.

Said thoughts sent more than his mind for a ride, the image of a naked McGonagall suddenly entered his mind, a lot of blood rushed from his head to his other head leaving a tent in his school trousers.

The transfiguration professor saw the tent given it was fairly obvious and sighed in annoyance, she thought back to a time she went through a similar experience with the boy's father.

Back when James was 15 and pulling the exact same thing Harry is doing now. McGonagall shocked James by sitting in his lap and daring him to touch her, of course James was frightened of the prospect and logical thought took over, leaving James to scurry from the office without much hesitation.

So McGonagall did as she did 21 years previous and stood up, she sauntered over to the stupefied Potter and carelessly dropped herself onto his lap.

She wrapped her arms around his neck and grinded her arse against his throbbing member she could feel through her clothes. She put her mouth against his ear and whispered "Now Mr Potter I, dare you to touch me the way you are thinking about right now" she added in a single gentle sigh into his ear at the end hoping the boy would copy his fathers actions and scurry away.

The problem with that logic is hoping that Harry Potter is afraid of anything including female interaction.

So when Harry squeezed McGonagall's arse with his right hand, McGonagall was quite shocked and released a sharp breath of surprise.

This only egged Harry on, his left hand went to her thigh and started to make its way to her waist all the while he dug his face into McGonagall's neck and started to kiss his way up her jaw.

McGonagall released a soft moan into Harry's ear, she bit her lip to try and hold in anymore sounds while a red tint took over her cheeks. She closed her eyes as Harry gave her arse another light squeeze.

She wanted to run her hands down his back but the back of the chair interfered with that so she ran her right hand up his shirt letting her feel his stomach. Her left hand kept its place on Harry's neck holding him against her.

She slowly started to grind her arse against his throbbing cock to which Harry released a groan and bucked against her. Quickly Harry stood with her in his arms and he placed her on top of her wooden desk.

She giggled and laid back down against the desk.

He pushed her so that she was laying down on the desk with him in between her legs, in a rush he started to pull her skirt off her legs while McGonagall was working on removing her robes.

Quickly her skirt was removed while her robes were now on the floor with her shirt revealing her black bra which was suddenly torn off with a spell from Harry.

Harry took a long look at his Professor's tits, one of his hands squeezed the surprisingly large pair of tits. He ran his fingers over her nipples, McGonagall responded with a moan.

McGonagall grabbed her wand and threw a spell at Harry that removed all his clothing in a flash, McGonagall quickly sat up so they were now face to face. She looked Harry in the eye while she spat into her hand.

She was still looking him in the eye while her hand made its way down to his cock and took it into her hand. She was still looking into his eyes as she whispered in a sultry tone.

"You like that big boy" Harry's expression answered that perfectly, his eyes were almost completely closed and fluttered closed when McGonagall slapped his cock against her pussy.

Quickly she pulled out her wand "Ducatus" Harry and McGonagall both felt a cold sensation that they both knew from experience "Now push baby, just push" she whispered while holding his member against her pussy.

She used her other hand to pull him into a searing kiss, they both pulled away with moans when Harry pushed forward into her tight cunt. He groaned at the feeling of her muscles almost pulling him in while she moaned at the feeling of his hard cock filling her.

"Fuck" her Scottish accent seemed stronger as she moaned out the word. "Fuck me Mr Potter" her words worked on Harry who grabbed her and started to pound her into the table.

McGonagall leant her head back and watched the ceiling as she was being fucked by her star quidditch student and Harry was watching her tits bounce while he was fucking his favourite teacher.

Her occasional slurred or murmur had Harry going twice as fast, she tilted her head forward and looked into Harry's eyes with her hair now in a messy bun with strands flying about her face.

"Cum on my tits" her breathing was heavy causing her to pant "cum on my fucking tits" she moaned nearly incoherently with want.

They were both groaning and moaning as the sound of skin slapping against skin echoed in the large room. McGonagall could feel her climax coming soon, she hadn't had a good fuck in a while afterall and she knew Harry would cum soon, he was good yes but he was only 16.

So when her legs involuntarily started to twitch and shake, and Harry's strokes got faster she started to furiously rub her clit while being fucked.

She quickly came with a long drawn out sultry groan that had Harry cumming as well, he quickly pulled out and came all over her. The white ropes of liquid landed straight on her face and slowly dropped down onto her tits.

She watched his balls twitch as they released the last of what they had all over her and smiled softly. She grabbed her wand and conjured a bed, she half limped over with Harry's hand in hers.

She collapsed onto it with Harry falling besides her, with her wand she used an obscure locking charm on her door.

"I think, we may need to have another…meeting later tonight Mr Potter, you should probably just wait for it while you are here"
