Tonks' Guard Duty (Ch. 2 - Staining The Couch) (Patreon)

Disclaimer: The characters in this story have been aged up. Hogwarts start at the age of 15, making Harry and all characters Harry encounter 18 or older.

Harry growled at the sight of the practically naked vixen on her knees in front of him, still dripping with his cum. The horny beast inside him took over, unwilling to let go of this sudden chance to get better acquainted with this mysterious Tonks. He reached down, grabbed her by the arm, and hauled her up, throwing her over his shoulder in one swift motion.

"Let's take this inside," he growled as he slapped her bubbly ass playfully, his voice deep and husky with lust. "Wouldn't want to disturb the entire neighbourhood now, would we?"

Tonks squealed as he threw her over his shoulder, but she wrapped her arms around his waist and held on tight, grinning from ear to ear. This was way more fun than guard duty!

Harry carried her inside, kicking the door shut behind him as he made his way to the living room. He tossed her down on the couch, making her squeal again as she bounced on the cushions. Harry stood over her, his cock still rock hard and throbbing with need.

"Now where were we?" Harry asked himself, reaching down and stroking his thick shaft slowly, making sure to give Tonks an eyeful of his impressive length.

Tonks watched hungrily as Harry started jerking off above her, feeling her pussy clench with desire. Her fingers wandered between her legs, teasing her swollen labia and soaking wet folds.

Tonks saw Harry's eyes flicker at the sight of her half-naked body on display. Her nipples had been rock hard and erect for some time now, begging to be fondled and sucked. Her pink pussy lips were swollen with lust, her slit already moist and inviting.

Her skirt, which did little to hide her moist pussy anyways, slid off easily, revealing her bare lower half. Harry groaned at the sight of her smooth, hairless mound, her pussy lips already glistening with her juices.

"Fuck, you're so wet," Harry growled, his voice low and husky with lust.

"What did you expect? I've been wanting you all morning," Tonks said with a smirk, spreading her legs wide and flashing her glistening cunt at Harry, inviting him to come closer. And while Harry enjoyed the view, she took the time to discard her bunched-up top, finally leaving her completely exposed.

Without warning, Harry lunged forward, diving face first towards her spread eagle form. His tongue snaked its way across her thighs, tracing patterns along her skin until he found what he wanted - that sweet spot between her legs. With a satisfied sigh, he dove into her depths, tasting her tangy nectar while exploring her hidden crevasses. As he feasted upon her womanhood, he heard her gasp and whimper under his ministrations. It wasn't long before she came undone beneath his oral assault.

"Oh... oh fuck!" Tonks screamed, thrashing her head side to side as wave after wave of pleasure rolled through her body.

But Harry wasn't done just yet. He kept going, relentlessly lapping at her sopping wet pussy, teasing her entrance with his tongue. He couldn't help but smile when he felt her trembling below him, knowing full well how sensitive she must have been after such an intense orgasm. But even then, she seemed insatiable, demanding more from him.

"Give me your cock, Harry!" Tonks demanded, pulling at his shoulders, urging him to mount her. She didn't care if they broke the damn sofa; she needed him inside her, filling her to the brim.

Harry's emerald eyes flashed with primal lust as he positioned himself between Tonks' quivering thighs. His cock, still slick with her saliva, throbbed eagerly, ready to claim its prize. He rubbed the head of his cock against her drenched folds, teasing her entrance, making her whimper and buck her hips in desperate need.

"You want this, don't you?" Harry growled, his voice thick with desire. He revelled in the power he held over her, the control he had over her pleasure. He loved seeing this woman like this, writhing beneath him, begging for him.

"Yes, please, Harry!" Tonks begged, her voice hoarse with need. "I need you inside me, now!"

With one swift thrust, Harry buried his cock deep inside her, making them both groan in unison. Her pussy was like a velvet vice, gripping him tightly, worshipping every inch of his shaft. Their bodies melded together, becoming one as they began moving in rhythm, driving each other to new heights of ecstasy.

Their bodies moved in a rhythm as old as time, a dance of passion and lust. Their moans filled the room, a symphony of pleasure that echoed off the walls. Harry's hands roamed her body, groping her breasts, pinching her nipples, making her cry out in delight.

Tonks had never felt so full before. The thickness of his cock stretched her walls wide, pushing her to her limits. Harry's pace quickened as he claimed her body, his cock pounding away, demanding more from her.

It wasn't long before Tonks' nails dug into Harry's back, scoring their length as another orgasm made its way up her spine. This time it hit harder than ever before, causing her entire body to shudder violently as waves of bliss washed over her.

"Fuck! Yes, Harry!" Tonks cried out, losing herself in pure ecstasy. "I'm cumming again!"

Harry grunted as he continued plowing into her, listening to her screams and whimpers. Soon enough, he too reached his limit. Feeling his balls tighten, he knew he wouldn't hold much longer. One final push sent him spiralling over the edge, triggering his release.

"Ahhh... fuck!" Harry yelled, feeling his cock twitch as rope after rope of hot, sticky cum spurted forth, coating her insides with his seed.

As Harry filled her up, he watched as Tonks' hair changed colour rapidly. It went from bright pink to a fiery red, then to a deep purple, then to a dark blue, and finally to a vibrant green.

"Yes, yes, yes!" Tonks squealed, her body shaking as she rode out her latest orgasm. "You're filling me up, Harry!"

And to think, just moments ago, Harry was miserable and bored, working alone in the garden, suffering through the Dursleys' unfair treatment. Now look at him, buried deep inside this enchanting witch, enjoying every ounce of her.

When they finally finished, Harry pulled out of her, leaving her panting and sweating on the couch. Her body glistened with sweat, and her chest rose and fell quickly as she caught her breath. Harry looked down at her, taking in the sight of her exhausted form, covered in a mixture of their juices.

"You're a dirty little slut, aren't you?" Harry asked, smirking down at her.

Tonks grinned up at him, her eyes sparkling with mischief. "What can I say? I've always had a thing for bad boys."

Harry chuckled as he flopped down on the couch next to her, reaching over and stroking her inner thigh gently. "Well, I guess I'll have to keep you satisfied then, won't I?"

"Oh, I certainly hope so," Tonks replied, winking at him playfully.

Her hair shifted colour once more, turning back to its original shade of bright pink.

Harry, still catching his breath, couldn't help but be mesmerised by the kaleidoscope of colours that Tonks' hair had just gone through. "What... what was that?" he asked, his voice still thick with lust.

Tonks grinned at him, her chest still heaving from their exertions. "That, my dear Harry, is a little thing called Metamorphmagus," she said, her voice filled with pride. "I can change my appearance at will."

Harry's eyes widened in amazement. "Really? That's... that's incredible," he said, his mind racing with the possibilities. "Can you... can you change into anyone?"

Tonks shook her head, her hair shifting to a deep red as she did so. "No, not anyone. I can only change into people I've spent some time around," she explained.

Then, with a mischievous glint in her eye, she stood up from the couch, and her body began to shift and change before Harry's eyes. Her hair grew longer, and her face became a little more angular. Her breasts seemed to shrink slightly, and her hips widened. Her ass, which had been toned and fit before, now seemed to fill out more, becoming rounder and softer.

Harry gasped. Standing before him then was his best friend, Hermione Granger, complete with her bushy brown hair and freckles. However, the baggy jumpers and jeans he had become so used to seeing her in where nowhere to be found, revealing her full, luscious figure.

Harry's jaw dropped as he took in the sight of his best friend standing before him, completely naked, his cum dripped down her thighs. He gulped, his throat going dry as he tried to swallow the sudden lump that formed there.

"Hermione?" Harry asked, his voice hoarse and scratchy.

Tonks - or rather, Hermione - smiled at him, looking more seductive than Hermione ever had. "Hello, Harry," she greeted him in Hermione's voice, batting her eyelashes innocently.

Harry's cock twitched at the sight of his best friend standing before him, her perfect tits bouncing lightly with each step she took towards him. He swallowed hard, trying to calm himself down. But it was no use; he could feel his erection growing harder by the second.

Where had Hermione been hiding those fantastic tits all these years? And why hadn't she told him about them sooner? They were magnificent! So big and plump, yet firm enough to hold onto without fear of falling apart. His hands itched to reach out and grope them, feeling their weight against his palms.

And then there was her ass. It jiggled seductively with every step she took, each movement causing Harry's heart to race faster and faster. The thought of grabbing onto those cheeks while pounding away at her tight pussy made his mouth water uncontrollably. He promised to fuck the real Hermione silly the next time he saw her.

But for now, he would make do with this magical version of her.

Tonks giggled at the look on his face, her eyes sparkling with amusement. "Like what you see?" she asked, her voice teasing and playful.

Harry had never heard Hermione's voice sound so sweet and sultry before. His eyes wandered over her body, taking in every inch of her stunning form. And when his gaze finally met hers again, he nodded eagerly, unable to hide his excitement any longer.

Without another word, Tonks climbed onto Harry's lap, straddling him and rubbing Hermione's moist folds against his aching shaft. Harry groaned at the sensation, feeling her wetness coat his cock. She leaned forward, pressing her perky tits against his chest as she whispered in his ear, "Let's give you a taste of what you've been missing out on, shall we?"

Harry couldn't resist the temptation as Tonks, disguised as Hermione, ground herself against his throbbing cock. He reached up and grabbed her luscious ass, pulling and playing with her plump cheeks as he moaned in delight.

She leaned in closer, her lips brushing against his ear as she whispered in Hermione's voice, "You want me to ride your big, fat cock, don't you?"

Harry shuddered at her words, nodding frantically. There was something incredibly erotic about hearing Hermione talk dirty like that. It sent waves of pleasure coursing through his veins, making him grow impossibly harder as he pressed up against her.

"Say it, Harry," Tonks urged, her breath hot and heavy against his ear. "Tell me how much you want to fuck Hermione's tight little cunt."

Harry didn't need any further encouragement. "Fuck yes!" he cried out, gripping Tonks' ass tightly. "I want to fuck your tight little cunt until you scream my name, Hermione!"

Tonks giggled, in a way that he had never heard Hermione do before. She wiggled her hips, grinding her slick folds against Harry's member, teasing him with every tiny movement. Finally, she lined up the tip of his head with her entrance and impaled herself upon him, her walls clenching around him.

"Oh, fuck!" Harry yelled, throwing his head back as he felt her heat envelop him. "Your pussy is so fucking tight, Hermione!"

"Mmm, that's right," Tonks groaned in Hermione's voice, sliding slowly down on his cock. "I've been saving myself just for you, Harry. Waiting for the day you'd finally push that big, fat cock of yours inside me."

Harry grunted as she slid down the length of his shaft, loving every inch of her hot, tight hole. Her warm flesh clung to him, holding him deep within her soft folds. Each surge pushed him deeper into her depths, touching places no man had ever touched before.

He groaned as she bottomed out, her ass resting against his balls. Harry couldn't believe how tight Hermione was, and he loved every moment of it. He wanted to stay buried inside her forever, relishing the feeling of being fully enveloped by her tender embrace.

But as much as he enjoyed the sensation, he knew that this wasn't the real Hermione.

Impulsively, Harry brought his hand down on her perfect ass, the smack echoing throughout the room. Instantly, the image of Hermione morphed back into Nymphadora Tonks, his Guardian's recognizable traits shining through as bright as ever. It seemed she couldn't maintain the illusion while under such intense pleasure.

Tonks yelped at the sudden pain, but she didn't seem mad. Instead, she grinned at him mischievously, her hair turning a fiery red colour. And Harry found he liked Tonks better this way; honest and true, and not hiding behind other faces.

"You like that, don't you?" she asked, her voice dripping with lust.

Harry answered by slapping her other cheek just as hard. His palm left a red mark on her milky white skin, standing out starkly against her pale complexion. It was such a turn-on seeing his handprint imprinted on her lovely round butt.

"So round, and so plump," Harry said, his voice dropping low with desire. "My perfect ass."

Tonks cooed, wriggling her curvy figure playfully. "You can have me whenever you want, Harry," she offered, arching her back so that her breasts jutted out provocatively.

Her nipples were still hard and begging for attention. Harry couldn't resist a moment longer. He leaned in and sucked one of them into his mouth, swirling his tongue around the bud.

He continued his assault, switching between her breasts, loving the way they bounced in his hands. His cock was still deep inside her, and he couldn't ignore the itch, the urgent need to thrust.

Harry lifted her up by the ass, only to slam her back down, causing Tonks to cry out in pleasure. He did it again, and again, each time with more force than the last.

Tonks moaned, her eyes rolling back in her head as she revelled in the sensation. "Yes, Harry! Just like that!"

Her hair changed colours rapidly, shifting from pink to purple to blue to green and back again. With every change, her pussy squeezed tighter around his cock, trying to milk him dry.

It was too much for Harry to take. He felt his orgasm building, threatening to spill over. But he held on, determined to make this moment last as long as possible. He wanted to remember this moment forever. Knowing he could make a woman this sexy come undone on his fat cock felt empowering.

He started pounding into her harder, their bodies slapping together with each impact. Sweat dripped off their brows as they both fought to reach their peaks.

Tonks screamed as her orgasm hit her hard, sending her over the edge. Her pussy tightened around his shaft, pulling the trigger on Harry's own climax.

"Ahhh... yes... fuck!" Harry yelled, feeling his cock twitch as rope after rope of hot, sticky cum spurted forth, coating her insides with his seed once more.

When they finally finished, Harry pulled out of her, leaving her panting and sweating on the couch. Her body glistened with sweat, and her chest rose and fell quickly as she caught her breath. Harry looked down at her, taking in the sight of her exhausted form, covered in a mixture of their juices.

Tonks grinned up at him, her eyes sparkling with mischief. "Well, that was fun," she said with a wink.

Harry chuckled, shaking his head. "You're insane, you know that?"

Tonks giggled, her eyes sparkling with mischief. "And proud of it," she replied, sticking her tongue out at him cheekily.

It was then that post nut clarity suddenly hit Harry. "Wait a minute," he said, narrowing his eyes suspiciously. "How come you could change into Hermione? I thought you said you could only become people you've spent some time around?"

Tonks shrugged nonchalantly. "Well, Hermione has been staying at the order house lately. So yeah, I have seen her quite a bit recently."

Harry gaped at her, his eyes wide with disbelief. "You're kidding, right? Hermione has been living with the order? Why didn't anyone tell me?"

Tonks froze, her eyes widening in realisation. "Oh, shit. I wasn't supposed to tell you that, was I?"

If the gleam in Harry's eyes was any indication, Tonks was in big trouble. "I am going to fuck every ounce of information out of you before the day is over," he growled, his cock stirring once more.
