Professor Potter
Chapter 1
When Harry first arrived in this new reality, he thought it was pretty strange. Dumbledore didn’t exist, some of the men he knew in his former reality were women here, and you didn’t get to start Hogwarts until you were eighteen. If that wasn’t bad enough, he hadn’t had a galleon to his name. Luckily, Headmistress McGonagall was very eager to hire him as the Defense Against the Dark Arts professor. Truthfully, she probably would have hired the first person to apply.
Today’s topic was Shield Charms, but the only thing being projected was a whole lot of incompetence. Harry got to his feet and pointed his wand at the blackboard. “The incantation is Protego,” he said, enunciating for those in the back row who thought they were too cool to listen. “You’ll notice it’s a nonverbal spell once mastered, but for now, let’s focus on getting the basic wand movement down.”
He broke off when he saw Hermione Granger in the front row, as always, staring up at him with stars in her eyes. There wasn’t a question on her lips for once. She just stared at him with a dopey expression.
Behind her, Parvati Patil whispered something to Lavender Brown, and they both snickered. Hermione’s shoulders stiffened, and she flicked her hair over her shoulder in defiance. It was as bushy as ever, sticking out at wild angles like a bush no one bothered to prune.
“Now, let’s try it together,” he said. “Wands out, everyone.”
There was a flurry of giggles, even from the Slytherins. Dean Thomas yanked his wand so hard from his robe that he nearly stabbed Seamus in the ear. Hermione’s hand shot up, but Harry ignored it. If given the chance, she would go on for half the class. Instead, he wandered the aisles, correcting a grip here, adjusting a wrist there, and pretending not to notice the lustful gazes from the female population.
Lavender was holding her wand with both hands, mouthing the spell with exaggerated lip movements, and glancing every so often at Hermione. Parvati blew a bubble with her gum and let it pop loudly. Harry flicked his wand at her, and her gum shot out of her mouth and hit the inside of the metal rubbish bin with a loud ping. Lavender thought that was particularly funny.
He heard a quiet, frustrated sigh at his side. It was Hermione. She was twirling her wand and biting her bottom lip. He tried not to look at her mouth. Her two front teeth were still prominent, and he knew she was sensitive about it. She was muttering the spell to herself, and Harry bent closer, lowering his voice.
“Try a gentler flick at the end,” he said, demonstrating the proper movement. “It’s about focus, not force.”
Hermione’s face flushed a dusky pink, and she adjusted her grip. “Thank you, Professor,” she murmured. Her hand was trembling.
Once their time was up, Harry dismissed the class and was nearly trampled as everyone stampeded for the corridor. Only Hermione lingered, straightening her bag and shuffling her parchment, as if she wanted to make this time with him stretch just a bit longer.
“Er … thank you, Professor,” she said again. She pressed her lips together, and her cheeks flushed pink. Hermione then darted for the exit.
As soon as she left, Lavender and Parvati swooped in, arms linked, chattering and glancing back toward the door. Harry started gathering his own things, only half listening as Lavender whined about how if there was even one more week of snow, she’d go positively mad.
They didn’t notice Harry watching them. Perhaps they did, Harry thought, because Parvati’s voice dropped and she said, “Did you see the way Hermione was practically drooling?”
Lavender cackled. “She’s so pathetic. I bet she doesn’t even …”
Harry coughed, and the girls spun around, suddenly acting prim and proper. “Good day, Professor,” they sang in unison, smiling prettily.
He rolled his eyes and watched them leave, the echo of their laughter trailing them all the way down the corridor.
Professor Potter
That night, the Gryffindor common room was crammed with people. The first-years were playing wizard chess. The fifth-year boys were huddled around the wireless, groaning at the news that Puddlemere had lost again.
Hermione sat alone at the far end of the Common Room, huddled behind a wall of books. Her quill scratched feverishly against the parchment. She’d been there since dinner. Lavender and Parvati were lounging by the window with their feet up on a velvet cushion, sharing a package of Ice Mice.
Hermione snapped her book shut and quickly stuffed everything into her bag. As she rose to leave, Parvati elbowed Lavender and called out, “Big plans for tonight, Granger?”
Hermione hesitated. “I have a meeting with Professor Potter,” she said. She tried to sound casual, but her voice came out a little too excited.
Lavender rolled her eyes. “Of course you do.” She did her best Hermione impression while using a simpering voice. “Oh, Professor, I simply must discuss my assignment with you … alone … after hours!”
Parvati’s voice dropped to a fake whisper that just happened to be loud enough for Hermione to hear. “You do realize he’s not going to, you know … notice you, right?”
Hermione’s lips thinned. “I don’t know what you’re talking about,” she said and walked briskly toward the portrait hole.
As soon as she left, Lavender said, “It’s sad, isn’t it?”
“So sad,” Parvati replied, shaking her head. “She has no friends. Not even the boys like her.”
“Why would they? She’s such a prude. She’s probably never even held hands with a boy.”
They giggled loudly and kept stuffing their faces with treats.

Hermione navigated the empty corridors, shivering from the chill. She clutched her bag to her chest and picked up the pace. Her heart thudded in her chest as she neared. When she reached the door to his private quarters, she hesitated a moment before knocking.
The door swung open immediately. Harry stood on the threshold, his shirt slightly unbuttoned and the cuffs rolled up to the elbows. He smiled at her, which made her tingle down below.
“Good evening, Hermione,” he said. “Come on in.”
She squeezed past him, inhaling his scent. The room was small and cluttered. Textbooks were stacked high, and there were various magical instruments scattered throughout the room. Hermione hovered by his desk, unsure where to perch.
Harry shut the door and turned to her. “Let me get changed,” he said. “You can … make yourself comfortable.”
He disappeared into the attached bathroom, and Hermione was left alone. She slid off her cloak and folded it neatly.
Professor Potter
Harry emerged from the bathroom with his hair damp and tousled. Stubble was shadowing his jaw, and he was wearing only a faded bathrobe that did very little to conceal the rest of him. The sight made her breath catch in her throat.
He padded to the center of the room and stopped. He looked her up and down, smiled, and nodded.
Hermione had discarded her uniform entirely. Her white cotton blouse and skirt lay in a careful heap on the floor. Her plain, white panties and bra were draped over the back of the chair. Hermione was completely naked, standing with her feet a shoulder-width apart. Her skin was glimmering in the lamplight. It was smooth, pale, and dotted with goosebumps. Her breasts were large enough to spill out of his hands, and they were impossibly perky, capped with light pink nipples that stood stiff and proud. Her ribs sloped down to a narrow waist, but his eyes were locked on her wide, fertile hips.
She’d turned away from him, propped her elbows on the desk, and arched her back so that her ass was the first thing Harry saw. Her two wonderfully jiggly cheeks were round, smooth, and parted just enough to reveal her pink, puckered asshole and the taut, hairless cleft of her pussy that was glistening wet. Her inner lips were light pink and slightly puffy, and her clit peeked out from between them, swollen with arousal. The outer lips glistened, almost trembling with anticipation.
Hermione looked back over her shoulder, and her cheeks were flushed a furious red. Her full, pink lips were parted in a faint, hungry gasp. For a moment, Harry could only stare. He then grinned, shrugged off his robe, and let it drop to the floor. His cock was as hard as a rock.
Harry approached her, and every inch of him was straining with desire. He stood behind Hermione and ran his hands across her lower back, tracing the small dimples above her hips. Her body trembled beneath his touch. She looked back again, desperate for approval.
“You arrived early tonight … I take it you enjoy our late-night conferences?” Harry said, caressing her delicate skin. Hermione shuddered and nodded.
“Yes, sir,” she answered with a trembling voice.
“Good,” Harry said approvingly. “Shake your ass,” he told her in a commanding voice.
Hermione obeyed instantly. She swayed her hips left and right, and the soft cheeks of her ass bounced around. She gave a little extra jiggle before bouncing her hips. Her hands clenched the edge of the desk tightly as Harry watched her ass cheeks clap together.
He cupped her right cheek and squeezed it, and Hermione gasped. The flesh gave way so easily under his palm. He parted her cheeks further, exposing her pulsating, pink asshole and the glimmer of her pussy, already slick with her juices. Her clit was swollen to twice its normal size, and her inner lips glistened in the light, practically begging to be touched.
Harry knelt down until his face was level with her pussy, and he blew a gentle stream of air across her exposed lips. Hermione shuddered, and her knees nearly buckled. Harry’s tongue snaked out and flicked the hood of her clit. She squeaked so loud that it echoed off the stone walls.
He licked her slowly and thoroughly, flattening his tongue against her and working upward from her clit, all the way to her asshole. He alternated between long, slow licks and rapid flutters against her clit, and Hermione’s breath grew ragged, and her whole body trembled.
“Professor,” she moaned, her voice muffled in the crook of her elbow. “Please.”
Harry smiled into her pussy, and he spread her wider and brought his tongue to her puckered asshole, giving it a gentle, teasing swirl before returning to her pussy. Hermione bucked, and her whole ass clenched reflexively. He repeated the action, loving the way she squealed and writhed with every pass.
He stood up, grabbing his cock and pumping it a few times. Hermione’s forehead had dipped to the desk. She was breathing in ragged pants, her hair tangled and frizzy around her flushed face. Harry pressed the head of his cock against her opening, but then paused. “I want your mouth first,” he decided.
Hermione looked up, her eyes glassy with lust, and scurried around to kneel on the rug at his feet. She took Harry’s cock in her hand, her thumb and index finger unable to meet around the thick shaft. Hermione then opened her mouth wide. Her tongue flicked the tip and swirled around the head, and she leaned in further, taking him in inch by inch.
“I taught you well,” Harry groaned approvingly as her lips slid down his shaft.
Her lips stretched around him, her jaw straining, and Harry let out a guttural moan as she gagged herself on his cock. She used both hands, twisting one at the base, while the other stroked up and down in time with the bob of her head. Her hair kept falling into her face, and she shook it away, determined to keep her eyes locked on his. Her eyes watered as she pushed herself to take him deeper. Hermione got him all the way to the back of her throat, and then she kept going until her nose mashed against the wiry hair at the base.
Hermione pulled back, gasping for breath, then dove in again. She was relentless. The wet noises her mouth made were obscene as they echoed in the small room. Her saliva ran down his shaft and onto her hands. She reached down with one hand and cupped his balls, squeezing them gently while she stroked him and sucked.
“Bloody hell,” Harry muttered. “You’re going to make me cum if you’re not careful.”
Hermione beamed with happiness and pride. She popped his cock out of her mouth with a wet smack, then licked the length from base to tip, savoring the taste of him. She looked up at him with pleading eyes and whispered, “I want you inside me, Professor.”
“On the bed,” Harry ordered. “Get into the position I like,” he told her, and Hermione rushed to comply. She got to her feet and practically ran to the bed. She crawled onto it on her hands and knees. Hermione then pressed her naked chest flat to the mattress while spreading her knees wide apart. Her back suddenly arched, and she lifted her ass high into the air. Harry saw that the insides of her inner thighs were streaked with wetness. His eyes then went to her bare pussy. Her pink folds were shiny and slick, and a fat drop of arousal dripped off of her engorged clit. Hermione was impatient and wiggled her ass tantalizingly.
Harry climbed onto the bed and settled behind her. Hermione moaned when he dragged the head of his cock up and down the length of her drenched slit. He pressed the head of his cock to her entrance and slid in until his hips met her ass.
Hermione yelped as her pussy stretched to accommodate his impressive size. Harry grabbed her by the waist and started thrusting. He didn’t bother starting out slow. He knew she loved it hard and fast. Her ass rippled with every impact, and the sound of damp flesh smacking together seemed to reverberate throughout the room. Hermione was incoherent, clawing at the sheets while babbling nonsense.
Harry leaned over her with one hand in her hair and the other around her waist. “Your pussy feels so good,” he groaned as her silky walls clutched his thrusting shaft.
Hermione could only moan in reply. She pushed back against him, matching his rhythm. She was greedy for every inch of his perfect cock. Her entire back glistened with sweat. He reached around and found her clit, pinching it between thumb and forefinger. Hermione wailed, and her legs wobbled as a shudder ran through her. Her pussy clenched tightly, and her walls fluttered in a hot, wet spasm. She came violently, and Harry nearly emptied his balls into her.
“Please, Professor … don’t stop,” she pleaded in a hoarse voice.
Harry gritted his teeth and pounded her harder, watching as her juices ran down her thighs and dripped onto the bed. He felt her muscles spasming around him as her orgasm intensified. He pulled out of her, and his cock was drenched and throbbing. “Do you want it in your ass now?” he asked, stroking his meat. Hermione had been nervous the first time he had taken her ass, but now, she loved having her tight hole fucked.
Hermione nodded, looking back over her shoulder. She reached back and spread her cheeks, exposing her tight, puckering asshole. “Please,” she begged. “I need it.”
Harry rummaged in the desk drawer, pulled out a little glass vial labeled “Lubrication Elixir,” and poured it over his fingers and cock. He lubed up his cock, then worked a finger into her asshole. Hermione whimpered and pressed back, forcing his finger deeper. He added a second finger, which made her moan.
“God, your body’s perfect,” he said, which made her blush deeply.
He pressed the head of his cock to her asshole and pushed in slowly. The little pink ring opened up, and his cock slipped in. Hermione shuddered and gripped the bedsheets tightly. She wiggled her hips, trying to take more of him into her ass.
He started with shallow thrusts at first, before going deeper. Hermione’s pussy was leaking, and a large wet spot formed on the sheet beneath her. Every time Harry thrust into her ass, she squealed and clenched tighter.
He reached around to her front again and rubbed circles around her clit. Hermione shrieked and started to tremble. She came instantly, her entire body wracked with spasms, and her asshole gripped his cock like a vice.
Harry fucked her harder as she babbled, “More, please, more … don’t stop, oh … oh god!”
Just as she said that, Hermione’s asshole squeezed his cock, and she squirted a jet of liquid that arced out from her pussy, soaking his thighs, the bed, the desk, and the rug. She did it again and again, every thrust milking another squirt from her pulsating pussy.
Harry felt his own climax building, and he knew he couldn’t hold on any longer. He pulled out at the last second and sprayed white ropes of cum across Hermione’s ass and lower back, spattering her with a sticky mess. Some dripped down into her ass crack and dribbled over her still-cumming pussy. He gripped her by the hips, steadying himself as the last tremors ran through him.
Hermione collapsed onto the bed, her chest heaving. Her lovely face was flushed and glowing with sweat. She looked up at him with cum oozing down her thighs.
She licked her lips and asked, “Did I do well, Professor?”
Harry lay down beside her and kissed her. Hermione moaned into his mouth and deepened the kiss. Her tongue instantly slipped into his mouth, and when she rolled onto her side, Harry took the opportunity to play with her sweaty, naked tits.
“I’d give you an Outstanding, with a chance to earn some extra credit,” Harry chuckled.
Hermione beamed and snuggled into his chest. Her hand was already stroking him back to full hardness.

Honestly? My only complaint about this new story (based on what I've read so far) is that the setup felt a little rushed so we could get to the age gap sex play...unless the Harry who is now DADA Professor at an AU Hogwarts is only a handful of years older than Hermione, due "our" Hogwarts starting at 11 and him being qualified to reach by age 21 or so makes more sense?

Hermione is an exceptional student in every subject including sex education.
