It was after his third year of Hogwarts ended that Harry returned back to the Kent farm, only to find the feelings between himself and his girlfriend had become more intense.
As the summer went on, it was almost like an awkward dance was taking place between Harry and Kara. Their relationship had progressed far, but it was the next step in their relationship that was giving both of them pause.
Neither had experienced sex before, and did not know how to go about initiating it. It was one day when Jonathan and Martha announced they were going away on a trip and leaving the two of them home alone that their eyes met. A message was conveyed between both himself and Kara, and Harry immediately knew in that moment what would happen that evening.
And so as the sun set and the evening began, he made sure to shower and adequately groom himself before heading to Kara’s room where she was waiting for him.
They had kissed and made out many times, felt each other up where he had greedily groped her clothed tits and she had obviously felt his bulge pressing against her. But this was the first time they would go all the way.
He walked in wearing only his underwear, cock already excited and partially hard in a way that was clearly visible through his undergarments.
Kara Zor-El sat on her bed wearing a thin bathrobe that was a bit too small for her busty form, and he could see the hint of lace underwear underneath. Blonde hair let loose and fresh from the shower, it framed her cute blushing face caused by his wandering gaze. Yet she too was eyeing him, gaze descending down to the impression of his shaft before gulping hard at the size of it.
But before anything could be said, he had crossed the room, eliciting a gasp from her lips as he pushed her on the bed. Her robe fell away to reveal the lacy white bra she wore underneath, hugging her big tits so perfectly.
She’s beautiful. Her blonde hair fanned out around her head like a halo, making his girlfriend look like a goddess in that moment. Her big blue eyes stared up at him as his palms moved to greedily grasp both of her breasts, feeling their sheer size and softness.
“H-Harry…” She moaned his name as he felt her up, her bra coming off as he took her right teat in his mouth and sucked.
Shaky feminine hands came up to dig into his dark locks, while his own hands drifted down to feel her core. She was already coated in her own arousal, soaking through her panties as his fingers plunged into her sopping cunt.
Kara’s body flexed as her mouth went agape, a silent scream of pleasure leaving her lips. She convulsed and shook under the force of her first orgasm, and Harry was amazed by how quick he pushed her over the edge.
But his own pleasure came next. Kara’s half-lidded gaze snapped wide when he pulled he pulled down his undergarments, his hardened cock flopping upwards before settling down under its own weight. “By Rao!”
“What?” He asked.
“I-It’s just way bigger than I thought.” She stuttered out, eyes never leaving his erect manhood.
He gripped it with inadequate fingers that didn’t fully wrap around his girth, before giving his cock a meaty pump. A small bit of precum left his tip, huge balls thrumming underneath and eager to shoot out load after load. He always knew he had a big cock, but the reaction from the beautiful blonde still boosted his ego quite a bit.
He moved closer, her legs moving up and to wrap around his sides as his cockhead brushed against her desperate core. Kara bit her lip and panted as he pushed just the head inside, all while Harry tried to control his raging lust.
He went slow, moving in inch after inch into Supergirl’s indestructible cunt as she moaned beneath him. Her labia lips were spread wide to accommodate him, hugging every last vein with a tightness that was indescribable.
Her insides felt hotter than a furnace, hugging and massaging him in a way that took his breath away. Harry wondered if sex was supposed to feel this good, or if it was those Kryptonian genes that did it.
It was when he was halfway in that he almost lost full control. Her walls were hugging his cock so tightly, the noises leaving her lips so enticing, along with the copious amounts of fluids that flowed out to coat his shaft. It was enough to drive a man to madness from pleasure. He gripped her hips tightly - remembering her tough physiology would prevent injury - before pushing hard.
He thrusted another inch inside before pulling back three more, before slamming back inside to conquer new territory. Kara became loud in that moment, wrecked moans and cries of pleasure leaving her lips that rattled his eardrums. But Harry didn’t stop, fucking her till every last inch of him was buried deep inside.
It was when his hips clapped against her bum and his cock was buried all the way to the hilt that he stopped to let her adjust. She had fully taken him, consuming every last meaty inch, and that was when she writhed and shook as another orgasm ripped through her.
Harry watched on in awe as she fell apart from the pleasure, before his own lust demanded he continue fucking her. His hips began to pull back before slamming forward, hands moving up to grasp her big tits that jiggled and bounced on her chest.
“Ugh! Oh- HAAARRRYY!” Kara screamed as he took her.
“That’s it.” He grit out through the blur of pleasure. “You feel so good!”
For a moment her blue eyes met his own. “H-Harry, can we change?”
He nodded, feeling a small line of sweat fall from his brow.
Next thing he knew, he was sitting on the bed, with Kara descending his cock as her hands gripped his shoulders for stability.
It was when he was almost fully buried in her once again that his own arms couldn’t help but move, hands reaching under to grasp her big bum. He could feel her fleshy ass through his fingertips, immediately knowing it was big and fit. But he would have plenty of time to study her rear later on, as Kara began to bounce up and down on his cock.
“H-Harry, Harry, Harry.” She panted his name with each bounce, fluids coating around his cock and providing additional lubricant as she moved. “P-Please, Harry…”
He could feel her feminine fluids leaking down onto the bed below, squeezing out the small space trapped between her cunt and his cock.
In front of his eyes, her big tits bounced up and down with her movements, ripe for the taking as he gave her left tit a small squeeze before leaning in to suck on her right. Kara only moaned louder, hands suddenly gripping his dark locks of hair once again as he felt her pussy squeeze him tightly.
She just keeps coming on my cock. He noted, feeling Kara’s body shake against him as she lost control for the umpteenth time.
There was a part of his mind that secretly worried about her superior strength. But in the throes of passion she seemed brought down to earth, literally weaker than ever. Her body was his to do with as he pleased, slumped against him and useless to resist because of the stimulation she felt within.
His own hands moved, grip tightening on her bum as he began to move her up and down on his cock with his own strength. Her ass clapped against his thighs as he felt his manhood straining, heavy ballbag coming ever closer to releasing its tremendous load.
PLAP PLAP PLAP PLAP
The sound was erotic and filthy, made even worse by her nonstop flow of fluids that coated his lap in arousal. He only picked up the pace, slamming Kara up and down on his pole.
“J-Just like that! O-OOOH! Y-You’re ruining me!” She looked fucked stupid, eyes wild and desperate as he chased his release. “P-Please Harry! Give it to me!”
He growled, using every last bit of restraint to hold off his own release. “You want my cum?”
“Y-Yes!” Her pupils were blown wide. “More than anything!”
His muscles strained as he gave quick, brutal thrusts that drove the air from her lungs. On his last thrust he pushed her up till just his cockhead remained buried inside, before slamming her all the way down his immense length to embed every last inch inside her.
Kara’s head shot straight up, spittle leaving her mouth, as his cock gave a great lurch before expelling its gigantic load into her. He filled her Kryptonian cunt with his wizard cum, then even more, his release seemingly never-ending as he pumped load after load inside her.
They fell over on the bed when everything was done, both of them fucked tired and satisfied. For being their first time, it went better than Harry imagined it would, if a bit wild and rougher than he initially pictured.

A spell went off, exploding a small mound of greenery and showering the surrounding terrain in dirt, which soon cleared to reveal the crater created by Harry’s bombardment curse. Yet he had no time to pause and study it, as a blue and red blur was flying straight towards him.
“Confringo!” The explosion of his accurate spell caught Kara mid-fight, causing her to yell in shock rather than pain as she was knocked into a grouping of trees nearby.
But soon she was back up, only taking a brief moment to reorient herself before flying straight towards him. He only caught a brief glimpse of her raised fist, before his wand was twirling. “Protego!”
A clear shield appeared between them, and Supergirl slammed straight into it. She groaned at the impact, as cracks spread through the conjured barrier. Sadly, his shield wouldn’t hold for long, as Kara began hammering at it with her fists. All Harry could do was try and uselessly hold the barrier, until his magic gave out with a particularly hard punch that shattered it.
CRASH
Clear shards of magic erupted outwards as Harry held a hand up to shield himself from the blowback, soon finding himself on the ground. Looks like she beat me once again.
It had become a regular occurrence for them to train, with himself using their spars as an opportunity to try out offensive spells while Kara tried to better herself at fighting. And while Harry could certainly get a few good hits in, there was little he could do against her Kryptonian invulnerability.
It’s not like I have any Kryptonite on hand. He brushed the dirt off his sleeve, before a radical idea occurred to him. Unless…
“Looks like I win again.” He looked up to see Kara floating above him with a smirk. Her hands were on her hips and face possessing an arrogant expression that was clearly fake. “And as the victor, I guess it’s time to claim my prize.”
Something had changed in their relationship since that night a month ago. The two of them now didn’t skirt around each other, but instead fucked like rabbits at every possible opportunity.
When the Kents were gone or busy, they fucked in Kara’s or his own bedroom. And even when her foster parents were home, the two of them would leave and find a clearing like this one to fuck in.
To be perfectly honest, it was a miracle they were able to get any training done at all. But then again, most of their training sessions devolved into this, being an excuse to mess around with each other.
She descended down to earth, kneeling over him before pulling down his trousers.
Her blue eyes almost seemed to light up as his cock flopped out, already aroused and ready for use. Before he knew it, her lips were wrapped around his girth, slurping and sucking noises filling the clearing as he tried to hold on to his sanity.
GLURK GLUCK GLURP
She kept going down his cock, taking him deeper with tremendous effort. He could feel himself entering her throat, then going deeper, as the noises somehow became even more obscene. It had almost become a hobby of Kara’s lately to try sucking him off, seemingly obsessed with being able to deepthroat his entire shaft. It wasn’t something that bothered Harry - the opposite, in fact - as he loved the view of the gorgeous blonde on her knees with his cock in her mouth.
That said, she had never taken him all the way to the base, usually only getting halfway down before it became too much to handle. Yet today seemed like the day she would get it, her stretched red lips getting ever closer to his base before he felt her kissing his crotch. Harry could hardly believe what he was seeing, his hands moving down to grip her blonde hair as he threw his head back in ecstasy.
“You really took it all...” He muttered, feeling Kara hum around his cock in response. Kryptonian biology is something else.
Soon she was moving back and forth, her tongue and throat worshipping the cock of her boyfriend as spittle and slobber made a mess of his lap.
GLUCK GLUCK GLURP
“Fuck, so good.” He groaned. “Damn, you’re doing amazing.”
His words of encouragement only seemed to make her work harder, head becoming a blur as she practically slammed herself up and down his length.
This is it. I’ve died and this is heaven. Harry felt like he was on top of the world, content to die if this was the last thing he could experience. What a great way to go…
He felt his manhood swell as Kara went at it, holding back a scream of pleasure through clenched teeth as he erupted into her mouth. She greedily gulped and swallowed it all down, working hard even as some of his tremendous load spilled past her stuffed lips.
When she finally pulled back and looked at him, Harry would admit she looked like a beautiful mess. Stained with copious amounts of saliva and his seed, along with tears that leaked out and ruined her makeup and mascara… Kara was still the most beautiful woman he had ever seen.
“Heh, bet you didn’t expect that.” She blushed at his amazed stare.
“No.” He agreed. “But if that’s what you do if you win our duel, I wonder what you’ll let me do if I win.”
She only grinned. “Anything you want.”
His cock throbbed at that answer, and suddenly he couldn’t wait for their next duel.
/////
“You’re wide open!”
Supergirl didn’t slow down as she cocked back her fist and slammed it against his conjured shield once again. Normally this would signify the end of their spars, but Harry was ready this time.
“Incarcerous.” He murmured, as ropes left his wand.
It was right as his shield shattered that dozens of ropes lashed out, wrapping around her midsection multiple times and sending Kara to the ground in a heap.
“Huh?” She writhed on the ground, before pausing and exerting brute force to snap all the ropes at once. She rose in the air before him, an almost mocking expression on her face. “Did you really think that would hold me?”
“I hoped it would slow you down.” He corrected, eyes closed and wand held carefully as he weaved through incantations. “After all, I needed time for my next spell.”
Suddenly, green light glowed blindingly bright in front of him, making him nearly cover his eyes as his conjuration spell went off. The green light coalesced into a single green stone, becoming less blinding but still bright to look at.
“No…” Kara muttered in shock, looking at the stone with disbelieving eyes. “Is that what I think it is?”
As if to answer her question, she suddenly stumbled mid-air, forcing her to float back several feet to get away from his conjured Kryptonite.
“It is.” He smirked. “I figured it would make our spars more fair.”
“How creative.” She admitted, recovering from her initial surprise. “But all I have to do is stay away from you to not be affected.”
“You think so?” Harry asked, before wordlessly picking up the Kryptonite with a nonverbal levitation charm. In an instant, he had moved the stone to float right next to her, sending Kara plummeting to the ground in a heap.
“Not…. Fair.” She murmured weakly from her defeated position in the dirt.
Harry only smirked, walking to stand over her with the stone still floating nearby. “What was it you said would happen if I beat you? That I could… do anything I wanted?”
He savored the look of realization that appeared on her face.
/////
Her cheerleader outfit was bunched up, torn, and clearly ruined, but he knew a simple reparo charm would fix it right up. Tears of mascara stained her face, and in her hands she held the kryptonite stone he had conjured.
To her credit, Kara was actually getting used to the radioactive material. It had even gotten to the point they used it during sex since he first conjured it weeks ago, almost like an insurance that her super strength wouldn’t show its ugly head and leave him snapped in half.
Either way, kryptonite or not, it didn’t stop Harry from pressing her up against the tree when she showed up to their regular spot wearing that sexy cheerleading outfit. Kara might have the excuse of having to wear it for practice on the school team, but that didn’t decrease the swell of his cock by the slightest bit.
He slammed into her brutally, his hips pounding against her ass as he gripped her hips hard enough to leave a mark. Ever since he had conjured Kryptonite, his girlfriend had developed a strange fetish with utilizing his ability during sex. It seemed Kara Zor-El liked to be on the bottom, submissive, to be the powerless one for once.
“Such a fuckin’ whore.” Harry groaned as he pounded her.
PLAP PLAP PLAP
“Yes, YES! I’m your whore! I’m Harry’s good little Kryptonian cheerleading slut!” Kara screamed.
He felt her cum, her cunt squeezing his shaft. Harry fucked her right through her orgasm, his hand reaching up to grab a fistful of her blonde hair so he could fuck her even harder.
It was almost difficult to think they started the summer as virgins, descending to where they were now. Rough and kinky sex was almost the norm, with Supergirl having the preference of having her back regularly blown out in the bedroom.
And so he fucked her harder, muscles straining from the effort as the clapping of flesh became almost deafening in that clearing. Kara screamed in ecstasy all the while, holding onto the Kryptonite for dear life.
That was when a sudden shadow descended upon them, making both Harry and Kara look up.
He only saw the red and blue outfit similar to his girlfriend’s, before he panicked in realization of just who had found them.
Several things happened then. First, Harry cursed and pulled out of Kara, causing a mess of fluids to spray out of her stuffed cunt. Next, Kara yelled, and threw the conjured kryptonite up at her cousin. Finally, Superman caught the kryptonite, blanched as he realized what it was, and promptly fell to the ground in a heap.
“You were spying on us?!” Kara was furious as she got up and descended on her cousin’s weakened form.
While Kryptonians were weakened by Kryptonite, Kara had been exposed to the substance enough to have built up a resistance of sorts to it. She was still physically weaker than him under its affects, but that didn’t matter when her cousin couldn’t even stand up.
“K-Kara, wait—” Clark tried to stop her, but he was too weak. The green stone was still near him, making him unable to move. That didn’t stop Kara though, who preceded to beat the daylights out of the man of steel.
Even after the incident was long over, Harry still struggled to believe that was his first introduction to Superman. All of them came out of it humiliated, him and Kara having been found and interrupted mid-passion, while Clark looked to have gone ten rounds with Doomsday when his beating was done with.
