Harry Potter was hard at work in the Dursleys' garden over the summer before his fifth year at Hogwarts. The Dursleys had tasked him with keeping their garden pristine and in perfect condition over the summer months. Harry, who was feeling at an all-time low mentally after just having watched Cedric Diggory die a few weeks prior, found the garden work to be a welcome respite.

He was toiling away in the midday sun, sweating profusely and wearing nothing but a pair of well-worn shorts, his t-shirt having been discarded long ago. He wouldn't normally dress like this with the Dursleys around, but they were all away at a Grunnings conference, so he didn't particularly care what they thought to his current indecency. His bare chest was glistening with sweat, and his muscles were rippling as he worked. He was using a pair of garden shears to trim the hedges, and he was doing so with a great deal of precision and care.

While he was working, his mind was wandering, as it often did these days. None of his friends had written to him all summer long, and he had been feeling very angry and isolated as a result. He had even considered just running away from it all, but he knew that would be irresponsible and foolish. He had to become a better wizard if he was going to be able to protect himself and those he cared about. And to do so, he knew he had to return to Hogwarts.

His only respite from these dark and destructive thoughts was to be found in the garden work. The physical labour was a welcome distraction, and the focus and concentration it required helped to keep his mind at bay.

He did wonder, however, what Dumbledore was thinking, leaving him alone with the Dursleys over the summer months. With Voldemort returned, what was stopping the Death Eaters from coming to Privet Drive and attacking him? The least he could ask for was a bodyguard, he thought. Someone who could protect him from the Death Eaters and keep him safe until he could return to Hogwarts.

What Harry didn't know was that Dumbledore had already made arrangements to ensure his safety over the summer months. And that those arrangements were currently keeping a very close eye on him. In fact, the bodyguard Dumbledore had assigned to protect Harry had decided she needed to protect him from as close a distance as possible. Which meant that she was currently watching him work just a few yards away, under a powerful Disillusionment Charm, her fingers buried deep inside her sopping wet pussy.

Nymphadora Tonks had been assigned to protect Harry over the summer months, and she had taken her job very seriously. She had been watching him closely for weeks now, but nothing much had happened. And while she took her job seriously, she had to admit, she was getting a little bored.

Harry throwing off his shirt and working topless in the garden was perhaps the most exciting thing that had happened all summer. And she had to admit, she was enjoying the view. His muscles rippling and glistening with sweat in the midday sun was a sight she could have watched all day. And as she watched him, she couldn't help but feel a little aroused herself.

Which was why she had decided to take matters into her own hands, so to speak. Protected by her Disillusionment Charm, she had snuck into the Dursleys' garden to watch Harry work. And as she watched him, she had found herself getting more and more aroused. It had just been all too easy to slip her fingers under her skirt and into her panties and start rubbing herself as she watched the show.

To Tonks, Harry was a sight to behold as he worked topless in the garden. His broad shoulders tapered down to his narrow waist, and his flat stomach was covered with a fine sheen of sweat. His arms were long and powerful, with well-defined biceps and triceps that rippled as he worked. Tonks was practically drooling as she watched him, her juices running down her thighs as she worked herself into a frenzy. So distracted was she by the sight of Harry's glistening muscles that she didn't even notice the fleeting glimpses Harry was throwing her way, as if he knew exactly what was going on despite the invisibility charm, but just waiting for the right moment to pounce.

Before Tonks knew it, her panties were around her ankles, and she was rubbing herself furiously as she watched Harry work. She knew she was putting a lot of trust in the Disillusionment Charm, but she couldn't help herself. The past few weeks had been so boring, that she had been desperate for some excitement. And watching Harry work topless in the garden had been just the thing to get her juices flowing again.

While one hand was buried deep inside her sopping wet pussy, the other was reaching up to pull down the straps of her top, exposing her breasts to the warm summer air for better access. But just as she was about to reach her peak, her left hand tweaking one of her nipples, a low moan escaped her lips, and she realised she had made a fatal mistake. Harry had heard her, and his eyes were now fixed on her invisible form, as if he could see right through her Disillusionment Charm.

Tonks froze in place, her heart pounding in her chest as she realised that she must have been caught. But before she could do anything, Harry had dropped his garden shears and was walking towards her with firm steps.

In her panic, she reached down to pull up her panties while simultaneously trying to move away from him his path, in case he couldn't actually see her, all the while hoping that the Disillusionment Charm would hold. But Tonks was a clumsy woman. In her haste, she tripped over her own panties and fell to her knees in front of Harry, landing hard on the grass between his legs. Her face was mere inches from his crotch, which left no doubt as to where her attention was focused when she lost control of her Disillusionment Charm and suddenly became visible in front of the Boy-Who-Lived, her naked tits out on display between his legs.

Tonks looked up at him sheepishly, her cheeks flushed red with embarrassment. She tried to play it cool, not doing anything to cover her nudity. Instead, she stuck out her hand to greet him, "Hi there, I'm Nymphadora Tonks, but you can call me Tonks."

Harry raised an eyebrow as he took in the sight before him. Mere moments before had he been praying for some contact with the magical world, and before he knew it his saviour had arrived, practically naked and kneeling in front of him. He glanced down at her exposed breasts, which were perfect in every way. They were full and round, with small pink nipples that were already hard and erect. He felt himself growing hard in turn as he looked at them, taking in every detail of her perfect form.

Then he looked down at her hand, the one she had presented in greeting. It must have been the same hand she had just used to pleasure herself, for her fingers were still slick with her own juices. Tonks seemed to realise this at the same time, for she quickly pulled her hand back, deciding instead to lick her fingers clean than try to make him shake them.

"Nice to meet you, Tonks," Harry said dryly, still confused and more than a little turned on by the situation. "Or should I say, nice to finally meet you. I take it you're the one who's been watching me all summer?" It was a wild guess, he hadn't actually known anyone would be watching him, but the pieces were rapidly assembling themselves in his mind. And in hindsight, it was obvious that someone would.

Tonks nodded, affirming his guess, feeling a blush creeping up her neck and onto her cheeks. She was so embarrassed, but at the same time, she couldn't deny the thrill she was feeling as she knelt there practically naked in front of the man who had just weeks ago won the Triwizard Tournament in an incredible show of magical prowess, her nipples rock hard with arousal and her cunt dripping onto the grass below. And better yet, if the bulge in Harry's shorts was any indication, he seemed to be enjoying the view just as much as she was.

Guided by her raging arousal, Tonks crawled further between his legs, reaching up to stroke the massive bulge that was forming in his shorts. "Well, since we've met now, maybe I can give you a hand with your gardening," she offered, looking up at him hopefully as she ran her fingers over the outline of what she was sure would be a massive cock.

Harry swallowed hard as he took in the sight of Tonks kneeling in front of him, her tits hanging free in the midday sun as she played with his ever-growing bulge. "Sure," he croaked, barely able to keep the lust out of his voice. "I mean, if you want to help, sure. That would be great."

He held his breath as she undid his shorts, letting them fall to his feet. His cock sprang free, slapping her across the cheek and leaving a bit of pre-cum behind on her skin. She looked up at him with wide eyes, then stared at the massive beast in front of her.

"Holy fuck, it's massive," she breathed, awestruck by its sheer size. While she was no stranger to sex, she had never seen such a big cock before, let alone touched one. And even though she was nervous, she couldn't deny the thrill she was feeling as she reached out to touch it, her hand shaking with anticipation as she wrapped her fingers around its girth.

She experimentally slapped it against her cheek a few times, getting a feel for how heavy and thick it really was. Then she leaned forward, opening her mouth wide and swallowing half of it whole. Harry gasped as he felt her hot mouth close around his cock, her tongue swirling around the head as she sucked him deep into her throat.

It was heaven. The feeling of her warm, wet mouth surrounding his shaft was almost too much for him to bear. He groaned as she started bobbing her head up and down, sucking him deeper and deeper into her mouth with each thrust.

Harry closed his eyes as he surrendered to the sensation. All the anger and frustration that had been building up inside him over the past few weeks seemed to melt away as he felt her mouth working him over. It was pure bliss.

Just as Harry was getting comfortable with the feeling of her mouth enveloping him, however, he felt her nails digging into his ass, pulling him even deeper into her mouth. He opened his eyes in surprise as he looked down at her, and he saw that she was staring up at him with ravenous eyes, her mouth stretched impossibly wide open around his girth as she worked to fit more of him into her mouth.

To his shock, she didn't seem to have a gag reflex. And while he had always known that he was packing a large package, he had never imagined that he could possibly fit it all into someone's mouth. But here he was, feeling her throat muscles contracting around his shaft as she pushed him deeper and deeper into her throat.

Harry's mind went blank as he gave himself over to the sensation. He moaned loudly as he felt her tongue swirling around his shaft, teasing his sensitive tip between every thrust. He couldn't believe how good it felt, and he knew he wouldn't last long like this.

And that seemed to be exactly what Tonks was after. Her mouth was slurping loudly as she worked to fit more of him into her mouth. Every once in a while, she would pull off his cock completely, only to plunge right back down again, taking him deeper and deeper into her throat with every thrust of her head.

Harry was getting close to his release, and he knew it. He could feel the tension building up in his balls, and he knew he wouldn't be able to hold back much longer. So he grabbed the back of her head and started thrusting his hips, fucking her face as she sucked him harder and harder.

Tonks moaned and hummed in satisfaction as she felt him thrust his cock in and out of her mouth, loving the feeling of his massive monster cock snaking its way down her throat. And with his hands in her hair, fucking her face, she finally managed to take all of him into her mouth, feeling his balls slap against her chin as he buried himself to the hilt in her throat. And that was what finally did it for Harry.

"Oh fuck, I'm gonna cum!" Harry cried out, his balls tightening as he felt the orgasm rushing through him. Tonks nodded her head on his cock, looking up at him with needy eyes, as if pleading with him to fill her throat with his seed. And Harry couldn't resist her, pushing his cock deeper into her throat as he shot burst after burst of cum straight down her waiting gullet.

"Take it all, you dirty slut," Harry growled, his voice low and husky as he hosed down her hungry throat with his seed. Rope after rope of cum erupted from Harry's throbbing cock, filling Tonks' eager throat as she struggled to swallow every drop. She moaned around his pulsating shaft, trying to drink down every ounce of his creamy load. Yet despite her best efforts, some still leaked out of the corners of her lips, drooling down her chin and dripping onto her breasts.

Finally, Harry pulled out of her mouth, his cock still rock hard and glistening with her saliva. He looked down at her, still panting heavily from his orgasm, and taking in the most beautiful sight of his life: Tonks, sitting there covered in a mix of his cum and her own juices, her breasts heaving with exertion and her eyes sparkling with lust.

"Wow," was all Harry could say, still too stunned to say anything else.

"I know, right?" Tonks grinned, wiping a strand of cum from her breast before licking it off her finger. "But something tells me you're not quite done with me just yet, hm?" she added, wiggling her eyebrows at Harry.

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!
