Chapter 1: It Seemed Like a Good Idea

“Back again so soon, boy?” Harry’s friend and occasional mistress purred as she greeted him at the door to her modest cottage. The young man shuddered as a submissive thrill ran down his spine, tied knots in his stomach, and then caused his cock to stiffen just the slightest bit. Her calling him boy always had that effect when he was in his submissive mindset. Luna said it was nargles, whereas he was pretty sure it was some weird psychosexual thing left over from Vernon’s abuse.
Luna gave him a devious little smile that he knew promised wondrous and terrible things and any thoughts of his uncle vanished from his mind.
“I, uh, I know it’s a bit earlier than normal. We just got together a few days ago.” The twenty-two year old blushed, thinking back to the debauched things he’d done for her during that particular session. “I guess I’m feeling it a bit sooner than normal,” he said, looking down in shame.
Harry had a problem. Not long into his relationship he had discovered an intense love for giving up control and being utterly dominated by his partner. Ginny, much to his dismay, was totally repulsed by even the slightest suggestion of anything non-vanilla in the bedroom. The salvation of his relationship had come in the form of a bizarre comment from Luna one day over tea. Apropos of nothing, she’d declared, “It’s a shame more men don’t like being being dominated and humiliated.” They had been talking about potions.
Her peculiar lack of propriety had been the spark that ignited a three-month-long affair filled with kinks and sexual acts Harry had never imagined.
Keeping all of this from Ginny was not his problem. As an auror, he had a very busy and chaotic schedule and his girlfriend never bothered to ask questions when he had to leave and return home at odd hours of the night.
His problem was that as soon as he ejaculated, his interest in submitting evaporated. In fact he would end up feeling slightly repulsed and even ashamed of what he had taken part in. Luna did her best to be understanding, but he knew it hurt her when he left in a hurry after cumming. They had tried prolonged orgasm denial, but he could only take so much before the frustration forced him to use his safeword and end their time together.
The eccentric blonde before him, dressed simply in a summer dress patterned oddly with creatures he was pretty sure did not exist and a pair of hand carved wooden clogs, stepped to the side and gestured for him to enter.
“I'm not about to complain,” Luna said happily. Her obvious cheer at his arrival made him feel even worse about his difficulties. She deserved better than someone who was only interested in matching her desires every once in a while. He knew she wanted something more fulfilling, and hated that he was basically using her to get off.
But he may have found a solution.
“Before we get started, I want to talk to you,” he said. She looked at him expectantly. “I was looking at some, uh, adult literature and found this.” He pulled a torn-out page from a magazine and handed it to her.
“‘A Guide to Seducing Muggle Women’, Harry? I don’t get it.”
Harry chuckled. “No not that, turn it over.”
The blonde domme looked at the other side and her devious grin returned in full force. “‘Libidus Maximus: Harder, Better, Faster, Longer.’ Oh Harry.”
“You probably can already tell, but it’s a spell meant to, uh, solve men’s problems in the bedroom.”
“But you’ve never had issues getting it up, Harry. It’s your emotional reaction after your arousal fades that spoils our fun.” Perfectly calmly, she added, “in short, you become a moody little bitch after sex.”
From anyone else, Harry would have been deeply offended by that phrasing, but he knew Luna meant nothing malicious about it. She just had zero tact sometimes. Besides, he probably deserved it.
“Well yes, but I think if I cast the spell with the Elder Wand it would be far more powerful and the arousal would last even after I cum. I wouldn’t become a, uh, moody little bitch. At least not right away. I could be your, um, boy, much longer.”
Luna’s eyes lit up with delight. “That sounds amazing, Harry! Have you tried it out yet?”
Harry shuffled his feet awkwardly. Making her smile like that did funny things to his insides that he hadn’t felt since he was a teenager.
“Well… not really. I tried it with my phoenix feather wand and it worked fine, though. I didn’t want to use the Elder Wand on myself without someone else to fix things if it goes wrong. It should be fine, though. It’ll just be a bit more powerful.”
Hermione, or probably just about any other witch or wizard would be a lot more hesitant to condone this without more precautions, but Luna’s father had never really taught her the meaning of the word ‘careful’.
“Sounds brilliant!” the blonde declared with a dazzling smile as she took him by the hand and pulled him toward her bedroom, clearly not interested in putting things off.
When Harry entered Luna’s bedroom for the first time, it had not been much out of the ordinary (as ordinary as a girl like Luna could possibly be). Over the course of their affair it had gradually transformed into a sort of half-normal bedroom, half-freaky sex dungeon. Implements and restraints of all sorts--many of which Harry had never found the courage to try--lined the walls and filled the drawers alongside the young woman’s everyday clothing. The closet, he knew, was enchanted: turn the knob one way and it opened to an ordinary space filled with dresses and shoes, turn it the other and one would encounter one of Luna’s biggest fantasies. A fantasy that Harry just couldn’t fulfill unless he could maintain a submissive headspace longer.
“You’re a bit overdressed, boy,” Luna giggled. One thing that Harry greatly appreciated about ‘Mistress Luna’ was that she never really put on an act. She always seemed like herself, even when she was paddling his backside raw. Harry had seen a couple muggle femdom pornos and the women in those were always sneering and acting like they hated their sub. Luna brought none of that, always sunny and playful, keeping Harry at ease.
Fingers trembling with a familiar anticipation, Harry took off his robe, then undid the buttons of his shirt and slid his arms out of the sleeves, allowing it to drop to the floor. As he began undoing his belt, Luna moved close and started gently tracing her hands along patterns across his back that only she seemed able to see. Harry’s trousers dropped to the floor and he stepped out of them, then removed his socks. He spread his legs slightly and put his hands behind his head, fingers interlocked. He left his boxer shorts on, knowing that his mistress preferred to remove those herself.
“Mmm, gooooood boy,” the young domme purred when she saw the sizable tent in Harry’s underwear. She grabbed Harry’s body and pulled it tightly against her own. Harry looked straight into her blue eyes, just as she liked, and saw an intense lust that mirrored his own.
“Thank you, Mist-” Harry began only to be cut off when Luna attacked his mouth with her’s in a searing kiss that left neither person unsure of who was in charge. Her hands reached up and laced themselves through the his hair, pulling hard enough to make the young man cry out.
Still smiling like a cat who’d caught the canary, Luna stepped back and dropped to her knees. Some might interpret it as a submissive gesture, but Luna’s dominating presence still filled the room, a sort of aura that made it impossible for Harry to see himself as anything but her helpless thrall.
“Do you remember your safeword,” she asked, putting her thumbs in the waistband of his boxers. The proximity of her mouth to his throbbing member was making it hard for Harry to think straight.
“Y-yes, Mistress. It’s ‘Horntail.’”
She began tugging his underwear down, ever-so-slowly. “And what happens when you say the safeword?” The boxers came down just far enough for his cock to spring free and bob happily in the air. Harry gasped.
“E-everything, oh, everything stops, Mistress.”
“Good boy,” Luna said as she wrapped her hands delicately around his shaft, barely applying any pressure at all. A small bead of precum had formed on the head and the young woman removed it with just the lightest flick of her tongue, making Harry groan.
“Oh my dear boy, you look almost ready to blow! We’ve barely begun!”
“Sorry Mistress, I’ve been on edge since I read about this spell.”
Luna released his cock and stood. She searched through his robes and retrieved the Elder Wand. “Well you better hurry up and use it!”
With a gulp, Harry accepted the wand and held its tip to the base of his penis. In as clear a voice as he could muster, he incanted, “Libidus Maximus!” and slid the tip of the wand up along the shaft of his member. At once, he could feel the difference from his phoenix feather wand.
Both wands gave him a slightly larger and firmer erection than normal, but the Elder Wand elevated his arousal in ways he couldn’t have imagined. His entire body seemed to throb with lust, and his desire to completely submit to the gorgeous woman before him increased tenfold. Overcome with sensation, the young man fell to his knees.
“Harry, are you alright?” Luna asked with obvious concern. She crouched down and took his face in her hands.
“Y-yes, Mistress,” Harry panted, trying to sort out his thoughts through the sexual haze that was coursing through him. “I-I just got a little overwhelmed. The spell worked better than I thought.”
“How do you feel?”
“Very, very turned on. Oh Merlin I’ve never been this horny in my life!”
Luna giggled. “Good to hear. Is that all?”
“N-no. I also… I really need to submit.” His eyes met hers with a pleading look. “Please, Mistress, please take control of me! Do whatever you want to your boy!"
Luna didn’t require any further imploring. She left Harry kneeling on the floor and retrieved a thick black leather collar from her dresser. Upon seeing it Harry’s body throbbed with a yearning to wear it so powerful that he nearly began to cry. Gently but firmly, the domme wrapped it around his neck. When the two ends met they merged together seamlessly, then the whole thing tightened just enough for Harry to be constantly aware of its presence.
“Mistress?”
“Yes, boy?”
“May I ask that you please restrain me? I don’t think I can keep my hands away from my cock much longer.” Indeed, he was literally shaking with the effort and only his inflamed submissiveness kept him from wanking himself off right then and there.
Luna stood him up and guided him over to her large four-poster bed where she had him lay down on his back. Then, with a simple snap of her fingers, manacles lept out from the four corners of the bed and latched themselves firmly around his wrists and ankles before pulling back until he was stretched out tightly.
“Thank you, Mistress,” Harry said. “I really don’t want to disobey you, but this spell...”
“I understand, boy.” Luna sat on the side of the bed and gently slid one hand along his torso, clearly admiring the way his stretched position brought out his muscle tone. “So now I have to decide what to do with my toy today,” she said brightly. “Do I want him to hurt.” She pinched one of his nipples hard and Harry gasped as the sensation seemed to go straight to his cock. “Or do I want to pleasure him to the edge of madness.” She slid one fingertip along the underside of Harry’s shaft, making him buck uncontrollably. “Or maybe I should do something far worse…” The blonde took her hands off his body and brought them to her own, fondling a breast with her left and sliding the right under her dress. Harry knew she wasn’t wearing panties. She never did.
“P-please,” Harry gasped as the young domme began to slowly pleasure herself, paying him no intention at all. In his current state, the young man couldn’t imagine a worse torment. Luna actually did stop, but only so she could lift her legs up onto the bed so Harry could see everything under her dress. The world’s most famous living wizard, the Man-Who-Conquered, Harry Fucking Potter, could do nothing but watch as the beautiful woman played with her body, teasing him masterfully. She would spend a minute or two sliding her fingers in little circles around her clit, then another minute or two plunging them in and out of her soaking wet pussy before returning to languid little circles.
Finally, after what could have been ten minutes or ten hours, she stopped and looked at Harry with lust-dazed eyes. “I meant to keep going until I came, but then I had a wonderfully mean thought!” The black-haired man gulped at her cheerful tone.
“Wh-what was that, Mistress?”
“The whole point of this spell is to keep you nice and obedient even after you come, right?”
“Well, I guess so…”
“So let’s test that! There’s something I’ve always wanted to do to a man, and I knew you would never go for it, but that was before you drove yourself all crazy with submissive lust. Will you do it for me?”
“What is it, Mistress?”
“It’s a surprise! Old moody bitch Harry would never agree to something without first knowing what it is, but I bet new and improved sub slut Harry won’t have any objections!”
Harry felt as though he should have a problem with it, but he just couldn’t find any concern within him. He was acclimating slightly to the spell, but still felt an intense need to submit. “No, Mistress. No objections. I’ll do whatever you want.”
Luna grinned wider than he’d ever seen at that. “We’ll see about that, boy. But for now, let me show you your surprise.” The woman leapt off the bed and went over to the dresser, casually stripping off her dress along the way. On her return, Harry pulled his eyes off her magnificent body just long enough to notice she was carrying a bottle of lubricating potion.
“Is it true that every straight guy fantasizes about fucking women in the ass?”
Harry blinked. “Uh, I-I guess. Every bloke I know at least.”
Luna nodded and to Harry’s amazement applied a small drop of the pale-lavender lube to her finger and began carefully stretching out her backside. “This stuff is nice because it only takes a tiny amount and it makes the sensations more pleasurable for the woman. Also vanishes any fecal matter.” Apparently satisfied in her preparations, the domme straddled Harry and positioned the man’s throbbing member at her rear entrance.
“Do you want to fuck my ass, boy?” She asked, looking down and clearly relishing the worshipful look on his face.
“Yes, Mistress! Oh yes!”
“Wound up as you are, you’ll probably cum very quickly no matter what I tell you. What do you think will happen after that?”
“I...I’m not sure, Mistress. Hopefully we’ll be able to keep going.”
“We’ll see.” And with that, Luna lowered herself onto her boy’s rod, and Harry nearly blacked out from pleasure. The woman wasted no time and began bouncing wildly atop him, awash in her own pleasure. Sure enough, it was only seconds of this before Harry began experiencing a climax like no other he had felt before. His entire body seemed to implode with pleasure before bursting outwards from the tip of his cock. Spurt after spurt of cum shot into Luna’s body, so much that it could only be an effect of the spell. The world spun around him and he was only slightly aware of Luna’s continued fucking. Blackness started to tug at the edge of his vision and he would have passed out had a sharp slap to his face not brought him back to reality.
“Boy!” Luna barked. Harry stared blankly up at her, still not entirely aware. Another stinging slap cleared his mind a bit.
“Ah! Sorry, Mistress! I came…” Luna finally stopped bouncing.
“I noticed. I couldn’t not notice. It was liking riding a bucking horse. But I haven’t cum yet and your cock is still rock hard… So the question is, do you want to use your safeword like always?”
Harry thought as hard as he really could, but the answer was already obvious to him. Thanks to the spell his arousal had faded only the barest amount and a desire to submit and obey still burned within his chest. He felt no shame, no revulsion. “No, Mistress, do what you want!”
Smiling brightly, the blonde did just that. Riding him for nearly half an hour as both experienced several thunderous orgasms. The special lube meant no chafing or loss of sensation, and it was only Luna’s exhaustion that forced her to stop and crash down onto his chest. She cuddled into him and Harry desperately wished he weren’t tied so that he could wrap his arms around the woman who had just taken him into another dimension. His cock had gradually lost some of its firmness and he didn’t feel quite as maddeningly horny, but he was still consumed by a deep arousal that went far beyond the physical. Most importantly, he felt no desire to call a stop to their time together. The spell may have made things more intense than he had anticipated, but it still had the desired effect.
“That was wonderful, boy,” his Mistress whispered into his ear. “You did so well.”
“Thank you, Mistress. I’ve never felt anything like that. Ever. It was…” he floundered, unable to put his feelings into something as small as words.
“I know,” Luna said contentedly, snuggling into his chest. They laid there quietly for a while before Harry broke the silence.
“Mistress?”
Luna looked up at his face. She had dimmed the lights so it was hard to tell, but he swore there was a look of sadness. “I know, the spell wore off and you want me to let you go. Here, I-”
“No!” Harry cried, startling them both. “I don’t want to be let go. Not yet. I just wanted to ask something.”
“What is it, boy?”
“You said you were going to do something I never would have agreed to before I used the spell. But anal sex with you doesn’t seem that out there…”
Luna giggled. “Oh, that. No, the anal wasn’t what I made you agree to. I knew you’d like that no matter what.”
Harry gulped. “So what did I agree to?”
“Well,” Luna began, seeming suddenly nervous. “There’s something I’ve always wanted to do with a man. You see, I think you must have shot around half a pint of your cum into my ass. Probably thanks to the spell. Normally I would just pass it out the natural way, but I’ve always had a fantasy about making a man clean me out. With his mouth.”
Harry’s eyes went wide. “You want me to eat my own cum?”
“Yes,” Luna replied.
“Out of your ass.”
“Correct. There’s no shit in there, thanks to the lube.”
“I, uh, wow.”
“You want to safeword don’t you? I knew it would be too much. Don’t worry, Harry, it’s fi-”
“I’ll do it.”
Luna paused. “Really? Are you sure?”
Harry nodded. “You’re right, Mistress, I never would have done this in a million years without that spell. But as I am now… I can’t think of a single good reason to say no to anything you want. And honestly… I think it’s kind of hot.”
The weight on his chest shifted and he felt Luna’s lips meet his own in a softer, but no less passionate, kiss than the one they had shared earlier. She pulled back and he saw a brilliant smile that shown in the low light. Any hesitation vanished with the fluttering of his heart. Still bound tight, he could only watch as Luna positioned herself over his face. Though it was dim, he could just make out a slight sheen of cum that had leaked out between her cheeks.
“What do you say, boy?” his Mistress asked softly.
“Please, Mistress, let me clean you.” Harry could hardly believe that these words were coming out of his mouth, but at the same time it felt completely right.
Luna lowered her body down and shuddered as Harry’s tongue went to work, first licking around her hole, then gently probing into it. She pushed slightly, allowing his seed to trickle out.
“Good boy,” she moaned. “Suuuuch a good boy.”
Both Harry and Luna knew, in that moment, that something had changed between them. They had gone much further than ever before. And while both revelled in the delightfully depraved act, they also worried where things might be headed beyond this. In the back of their minds was a question: what happened when the spell finally wore off?
