As weeks passed, Tony started to grow accustomed to teaching, he was even starting to like it, but what he enjoyed the most were the meetings with his favourite student. Hermione was a clever woman, and an excellent witch, she had a clear idea of what had been wrong in the program and what was necessary to change, and for wizards to know. On another part, he loved the bickering, she could also be incredibly stubborn and really opinionated, just like him, although usually he only fought to rile her.

In general, life in Hogwarts was something he could definitely get used to, and yet, the most he learned from the magical world, the most he wanted to just go out and see it. For now though, he was just happy to share the whole thing with her, even when their late night meetings were actually just class related, they were still teasing each other, fighting a lot or just talking about a bit of everything. Last few nights, they always ended goodnight with a hug or an innocent peck in the cheek.

"I'm telling you, they've been ready for fight club for like two weeks, you haven't even told Steve about it, have you? Unless you're planning on doing it all by yourself. It's almost time for winter break..."

"Fight club? Don't you know first rule it's not to talk about it?" He knew his students were aching to play with some fist violence, even most of those nasty purebloods, but they were the reason he had not started it yet, he was afraid they would only learn to beat the young students physically.

"For Merlin…" Hermione's neck was starting to turn red with irritation as she rolled her eyes. He just liked too much that -I'm like this short of punching you- look, her hair got even a little more wild, presumably something to do with her magic, her skin got a bit red and her eyes glowed almost gold. Also, she tended to get closer to him the angrier she got, in case he actually decided to punch him.

"Okay, okay, don't fret, I'll tell him this afternoon. I'm thinking Nat and Clint would be good professors too, seeing they are basically Russian army." He said touching her arm his hand. They were in his office, yes, he actually had an office, all classic with a fireplace and everything and a door that led to his bedroom, not that he would mind having their meeting there, but he would have to do with the sitting room in front of the fire, which was already a bit enhancing by itself.

"That would actually be a good idea…"

Dum-e ran into the room, being chased by a bewildered Dobby, still trying to get him to talk. It had been a whole achievement to even get him to work inside the castle, but he had been working for days with Bruce, studying the dynamics of magical functioning around electricity, and surprisingly professor Snape. Sure, he was bitter as hell, but mostly it was just part of a sarcastic personality, something he could resonate with. He was also fan of annoying him, but they were too much of a science/magic person to let the opportunity of figuring it go, it helped that he was of a muggle upbringing in part, so he was familiar enough with both worlds to get the basics of their interaction. Actually Hermione had been really interested in it too, well, she was interested in anything she could get knowledge from, and she did was a walking library, which was useful. So they had been able to make Dum-e work inside the castle so far, he even got him to talk, a bit like Jarvis but no so quite intelligent, since he didn't wanted another Vision case, but for some reason he refused to communicate with Dobby. Steve had thought it had to do with them both being 'assistance' type of beings, and he felt kind of jealous, Tony didn't think he was that intelligent yet, so Hermione had talked to him, and it turned out he just enjoyed making Dobby run after him, like a brother.

Hence, Hermione burst into laugh with the sight of the little elf running behind the robot.

"Fucking human robot! I just want to talk to you! You iz stop running!" Now that made Tony laugh, if only Steve could see.

"Dobby!" Hermione reprimanded, stifling the laugh, not even her could not find the elf swearing amusing.

"Dobby is just wanting to know what color of the person robot in his favorite, so he can knit him a scarf, just like Miss Hermione knitted to Dobby." This time, the elf actually pouched. It was one of the weirdest interactions he had had in this world yet.

"Dum-e, cut Dobby some slack and get out there-" There was a squeaky metal sound as the robot collided with the shelve next to the couch he was hiding behind. "Dum-e…" He said warningly.

The robot came out his hiding spot and turned to the elf but said nothing. It wasn't necessary, Dobby's eyes glistened in relief, the mere fact of him acknowledging him was a whole event.

"Sir Dum-e, Dobby is not wanting to bother you, Dobby is just wanting to know what Dum-e favorite color is."

There was another squeak, almost like a sight from the robot before he spoke.

"I don't think I have a favorite color, Sir Dobby, but Sir's suits colors are red and gold, I would wear that."

Why would the elf and the robot call Sir at each other was out of Tony's comprehension, but Hermione had a radiant and amused smiled, proud even. She had knitted a lot of garments for Dobby and Winky (the one elf Dum-e didn't seemed to mind following so much that if was not a robot one would think he had a crush on) in the past, and the fact that Dobby wanted to knit him something only meant he was just a fond of the robot as he was of the elf.

Hermione a Tony looked at each other, both with an amused smile after the absurdity of the whole situation that they, him as a muggle and her as a muggle born, would never thought to see.

"Just like Gryffindor colors! Dobby is making you a Gryffindor scarf!" Exclaimed the excited elf and disappeared with a pop. As soon as Dum-e got out of the room in search of something to do, they both burst into laugh.

"An elf, wants to knit my robot a scarf." Said Tony seriously, and then broke again, it was just too much.

"He means well." Hermione said still laughing a bit as she sat right next to him and slapped him in the arm. She had been so excited when they made the robot work she screamed, jumped and hugged him, she clung to his neck and he spinned her in circles, and then they just rest there in each other arms. They knew it was… what it was, but it was getting harder to contain, and as time passed, it was also getting harder to remember why should they.

"I know, and I'm sure he got it from you." He said, lifting a hand to stroke a curl on the side of her face. "You're a sweetheart."

"A sweetheart!" She almost yelled with indignation. "I am not a sweetheart, I am a powerful witch thank you very much."

"I know you are, relax witch." He said amused. "I meant that as a compliment. You do know what a compliment is right?"

"And you know you are a very…obnoxious…man, right?"

Tony laughed, that was getting to be their routine, but it never got old.

"Then you most like obnoxious men. And here I thought you just had good taste." He said as he got so close to her that she could feel his warmth trough the clothes, were their legs and arm touched.

"Well, I did dated a famous world class quidditch player, so I guess you are right." She smirked, hoping to get a reaction with that. And if Toy didn't felt a pang of something he didn't show.

"Oh, well then. I have a good taste too." He whispered that last in her ear. She felt his breath in her neck causing goosebumps in her skin as the tension flew rough her body, that known energy she felt that first night the danced at the club settling in her chest.

They stared into each other eyes, no longer able to even dissimulate how much they wanted to kiss. She inhale in anticipation, and that was all sign he needed to close the distance between them, she closed her eyes and moved forward too, parting her lips and touching them to his. They kissed, slow but passionate, all the energy they had been containing all those weeks pouring from their lips. She touched his lower lip with her tongue and he let her in, caressing it with his own in a sensual rhythm. Her arms went around his neck as she pressed to him, one of his hands moved to her waist, circling her and pressing her to him and the other went to her head, fingers deep in her hair.

They breath was starting to get heavy, but they didn't had any intention to stop. They kissed like that, only getting more passionate for what felt like seconds but was really almost 20 minutes, but a small whimper of satisfaction of her ignited something in Tony and the kiss got harder, faster, he set her on the couch and over her, her legs wrapped around him. Hermione's hands started to roam his back and his chest as hi undid his tie and tossed it aside. He then started to undo her cloak when the space of the couch just was not enough, he knew he probably should stop but he didn't wanted to, and neither did she. They separated just a bit to breath, and locked eyes, silently deciding whether to stop or just toss the rules. He knew what he wanted, although he felt a bit responsible, so ultimately it would be her decision.

"Would you… care to… show me your chambers?" She finally managed to say, because fuck the rules, she had been adequate all that time and had only gotten her frustrated, she had even gotten to the point where she woke up agitated from wet dreams and had to relieve herself.

She didn't had to tell him twice, he took her in his arms, her legs still wrapped around him. "Hold tight." He said as he lifted her and walked to his room, setting her on the center of his bed. She waved her hand to lock the door and sit in the bed. Gulping down what she hoped was a discreet lungful of air, she looked around the bedroom. The bed was large, with four-poster, like all the other beds in Hogwarts, and dressed with heavy dark, deep red curtains and canopy. It was larger than the students beds, maybe because they were meant to always sleep alone, and this was a faculty bed, who was to sleep comfortably and with whomever they wanted, and he wanted her.

They must've look funny, she in her school uniform, and him in his casual suit (minus the tie) twenty year older than the woman that was currently untying her school robes in his bed, followed by her tie and sweater, yet it had never felt more perfect. She slided to the edge of the bed, and he walked to stand above her, lowering to brush her lips with hers. She was completely nervous, but utterly aroused, even by his mere physical presence, despite having shared a close space during meeting for weeks. But right now, with his nose brushing her as they kissed, she didn't care, she just knew she needed him.

"Are you sure you want this?" He said in a last demonstration of chivalry, hoping for Thor and all the gods existing she didn't backed off, cause would surely kill him.

She took the top button of her blouse and slowly undid it, and then the second, until she reached the last and let her blouse fall in the bed behind her. "I'm sure…" She said, barely making a sound from pure desire.

It was all Tony needed as he kissed her, leaning her fully onto the bed and accommodating between her legs, they kissed long and wet while he undid his own buttons trying to get out his shirt. With another wave of Hermione's hand his shirt, shoes and trousers flew away, making him laugh. "A little too anxious, are we?" He teased her, and she just kissed him harder, like he wasn't just as turned on as she was, if not more. He stared sliding down her throat, kissing a licking and biting, tasting her perfect skin, while his hands roamed all over her body, caressing her sides, her legs and her perfect stomach. Her hands in his head, intertwined in his hair as he slowly kissed further down her canal, reaching for the clasp of her bra and unclasping it. He took the now offensive garment aside and turned to see her, she was stunning, aroused and more beautiful than he had ever seen her. He started to slowly kiss around, never quite reaching his goal, like the tease he was, so she yanked his hair in frustration. "Tony…" she moaned, he couldn't have his girl unsatisfied now, did he? With just the tip of his tongue he started to circle her right breast, and then flat out licked her nipple eliciting a gasp of pleasure from Hermione. He did that a couple of times more before taking it fully in his mouth and start sucking, this time she let out soft moans and sights. When he was sure it was enough, he started to kiss between her breasts to give his left nipple the same treatment. Without even thinking Hermione started to rub her thighs together looking for friction. At the movement, Tony slided a hand down her side, tempting her, caressing her legs and the inside of the thighs making her more frustrated. He slide his hand up her skirt, and toyed with her underwear, she was so hot by now she didn't even bother vanishing her clothes, and Tony may felt a bit of guilt for bring with one of his students, but would be lying if he said that the school skirt didn't turned him on.

He slided a finger on one side of her panties, testing the field first and finding her quite wet and ready, he moved his finger up and down a few times to finally start rubbing the little nub and she exhaled in relief. He continued to lick and suck her nipple and bite her breast while rubbing with his thumb and his middle finger went down to circle her entrance, what made her push her hips, Tony laughed low at this and kept his ministrations until one finger was inside if her, by then she was moaning and crying in pleasure not as loud as he thought he could make her. By the tightness of her body and her temperature increasing he knew she was close, he let her nipples and stop rubbing, but she wasn't even protesting yet when she felt his tongue circling her clit and his finger entering her again, finding her g spot, it didn't took long, just a few seconds later her body clenched and a thin layer of sweat appeared as she let out the most erotic form of his name he had heard. He stayed there until she completely came and got back from the clouds. The room got almost silent, only their agitated breaths disrupting it. When he thought she was calm enough again, he went up to kiss her, Hermione tasting herself in his lips and finding out that turned her on even more. This time, all clothes flew across the room, not a single barrier left between them while he positioned between her legs. "Wait." She said, posing her hand over her belly and whispering some words. "Contraception." She just said, and continued to accommodate him on top of her. Usually, she was a bossy and controlling person, but when it came to this, she liked to have someone in control, leading her, controlling her even. She was about to have sex with her teacher after all, she liked to have a figure of authority in bed.

When they were ready, he leaned in and kissed her as he slowly pushed inside her. As soon as that happened, both felt a jolt of energy pass thought them, like this was so much bigger. They kept on occasionally kissing while he started to pump, slow and at first, but as it was building for both of their releases he got faster, fasters and harder, Hermione couldn't kept the moans and cries of pleasure. Tony himself was grunting an occasionally moaning, but he couldn't hold it much longer, seeing he had desired so bloody much, and felling something magical pass between them with each thrust. She scratched his back and clenched herself, and at the feel of her nails in his skin from her pure pleasure and his dick being choked with her clenches, he came, pulsating inside her as he pumped as deep as he could. Hermione came again, from her own movements and Tony's noises and movements and the whole experience where she could feel her magic intertwining with something else, she came, joining Tony in a kiss.

They laid there together, members all over each other, comfortably from a Tergeo Hermione casted to clean their mess, as they were too spent to take a shower and refusing to get apart.

So they just, laid there, looking at the starred ceiling, Hermione wondering how did he got a starring ceiling and thinking that Dobby most probably did it, since she just had the most amazing night and didn't wanted to think anyone else entering in her….what, bedchambers.

Her what?

Tony was marveled, he had never felt like this, and even thought he knew his feelings for the girl had been growing over the weeks, it wasn't nealy just liking her anymore, it went beyond being in love. But could he?
