When math gets interesting.


This is a follow up for chapter 33 aka more Believer Queen.

And a special thanks to my beta LMPsisterhood for the invaluable help with this chapter. I'm sure this would get stuck and forgotten if it wasn't for the best beta ever! :)

Anyway, enjoy!


The chess tournament was reaching its peak at the Charmings' loft when Henry's phone buzzed with a strange message from his mother. She told him to meet her in the classroom where he teaches some advanced math to anyone who's interested. He was teaching five students now and they were showing promising futures, if they keep up with the good work.

He stops at the gate and hopes he hasn't done anything stupid without realizing it. He can't understand why Regina told him to meet her there on a Sunday afternoon. He pushes the gate open, closing it as his hands start to sweat.

The corridors are dark and his footsteps echo in the stillness of the empty school. He turns left and climbs a staircase, turning right as he spots the light coming out of the open door at the end of the hall. He swallows hard and walks slowly as dozens of scenarios run through his mind.

His breath is shallow when he closes his eyes and steps inside the room, ready for a lecture.

"I'm wondering, professor, if you can help me with this formula."

His eyes snap open and he gasps. She's faking concentration as her eyes are glued to the white board. He would believe her to be one of his students, if it wasn't for the fact that what she is wearing is not part of the school's dress code.

Regina is wearing a small red and black plaid skirt; it's so small he can actually see her buttocks, which means she's possibly wearing a thong, and he adores when she uses them only for him. He groans and fidgets nervously as she turns to him. The shirt is so tight it looks like it will be torn apart with the next deep breath she takes. Regina spots where his look is and smiles; she pops two buttons free and his eyes bulge as the view of her cleavage makes his jaw fall and his cock twitch, just like it always does.

"I'm trying to understand how to solve this formula, but I apparently am missing some important detail, can you help me?"

He stares at her while she crosses her arms over her chest. Her luscious breasts tease him mercilessly as he spots the edge of the black lace bra barely covering them.

"Well?"

Her voice snaps his senses back and he walks towards her, stopping behind her small frame to look at the board. He chuckles as he realizes she's actually picked a random formula and is trying to solve it. He knows she can do it if he teaches her, but he's not interested in numbers or how to solve math problems when she bends down to retrieve something on the floor and brushes her rear to his front.

There's a moment of hesitation when he looks at the open door. It's Sunday and he shouldn't worry, she's the mayor after all, so he grasps her hips and fits them to his front. Her moan is delightful and, the way she gasps, tells him she loves his initiative.

"This is a very advanced formula, Ms. Mills," Henry uses the worried teacher voice when he places his hand on her waist; she straightens her back and hisses when he runs his tongue up the slope of her exposed neck. "We haven't had enough time together for me to teach the fundamentals to solve such problem."

"Then teach me, professor," she turns her head and grins when he licks his lips while staring at hers longingly.

"This might turn into a long, long class, Ms. Mills!"

"I have all the time you need, professor," she takes a couple of steps out of his arms and turns her back to him, the tantalizing curve of her butt tempts him with every small step she takes.

She sits on a chair in the middle of the room. The students' desks are gone somehow and there's only this chair where she's sitting and Henry's desk in the corner. He observes as she crosses her legs as soon as she sits. He's looking at her so intensely he could burst her into flames, if he had any means to do it, but he knows he'll do it anyway when she lets him have his way with her.

And that's how his jaw drops to the floor again, as she decides to pull a Sharon Stone and tease him with the full view of her naked sex.

"Fuck!"

"You use that word way too much, professor!" Regina's voice is both amused and stern, and Henry feels like his shorts will tear apart any moment now. "And that is not proper vocabulary for a teacher."

"I don't know what you were expecting from me, Ms. Mills," he takes a few steps closer to her, hand brushing against his crotch as he already imagines those lips wrapped around his cock.

"I expect you to teach me how to solve this formula, sir," she pulls a sly smile and suppresses a chuckle when Henry fails to hold back the groan that rumbles out of his mouth.

"Fuck, mom."

"I suppose you have a job to do before we get anywhere near that, sir," Regina notices his reaction when she calls him sir and smirks. This is going to be fun. "That bag over there," she points her finger to a black satchel sitting close to the door, "take it and go dress properly, professor," she closes her legs and acts like she's only interested in his brain. "You can't teach me dressed like that."

Henry gapes at her for a whole minute before she gives his hip a pat. He blinks quickly and finally wakes up, walking towards the door, picking the bag up and racing to the bathroom to change. He shakes his head with an amused smile as he strips and puts on the usual clothes he wears for working days.

She's going to ruin this particular shirt as well as the pants, he thinks, once he won't be able to go about his classes wearing those pieces and remembering what happened.

The mirror is a bit dirty, but Henry can see his reflection glowing in the yellow light. His cock is half hard already and he can't wait for the moment Regina will open those beautiful legs for him to fuck her senseless, and he has to chuckle in amusement. She's always so eager and ready for anything he suggests, but he secretly loves when she does things like this for them, especially after the amazing time they shared only the night before.

He's walking quickly and fixing his tie when he enters the classroom to find her staring at the white board.

"Now that I am properly dressed, Ms. Mills," Henry uses his usual tone for teaching as Regina, once again, bends down to retrieve a pen and manages to flash her pussy to him. She looks over her shoulder and tosses him a wicked grin. He gapes at her another time and manages to suppress a groan. "How can I help you?" He coughs to hide a whimper as he waits for her next move.

"Come closer, professor," Regina looks at him in such an innocent way she almost fools him into believing she's actually interested in math. "Please?"

Henry does as he's asked and stops just a few steps behind her, hands practically tingling with need to feel her smooth skin under his touch, but he will play this game for as long as she wants. He knows the reward in the end will make up for the impatience he feels right now.

"Alright, Ms. Mills," he takes a step closer and smiles as goose bumps run down her arms and neck. "I'm here for you."

"Can you, please, explain to me why this variable is so important to solve the problem? If I understood it correctly, I have to comprehend its connection, so to speak, with the other elements of the formula."

He eyes her with curious amusement. That is indeed an intriguing question, and he's quite sure she's made some actual research in order to give him something to think about. Maybe she's just playing him, but the fact is that his brain is in full teacher mode as he thinks about her question and begins to ramble about how the variable helps understanding its use in Cartesian planes.

Henry can't see the smile on Regina's lips as he is still behind her, speaking with a passion and adoration for the subject she only witnesses when they are slick with sweat, panting and with limbs tangled inside her bedroom. He walks past her and is now waving his hands and using his fingers to explain better, rambling a bit more about ellipsis and graphics and how easy is to understand math when you let your mind flow with the numbers. His passion is endearing.

She doesn't understand a single word of what he's saying, of course, but for some reason Regina gets aroused by the minute with the unexpected combination of his professional tone (since he broke the puberty barrier, his voice has done wonderful things to her – even before they started having sex) and the way he looks dressed like that, she now feels the need to rip his clothes apart and ride him into oblivion.

"And that's how that variable relates to the rest of the formula," he finishes with a lovely grin gracing his lips as he turns to her.

"Fascinating!"

"You didn't pay attention, did you, Ms. Mills?"

"I did not, professor."

"Why is that?"

"That voice of yours," Regina touches his lips and licks hers as she is now craving the taste of his mouth on hers. "It does things to me, professor."

"Oh really?"

"Yes."

"But that's not a good reason not to pay attention when I'm explaining something so interesting to you."

"True, but there's also the case of that wonderful ass of yours," she touches his ass, "it's so tightly confined inside your pants; it distracts me way too much, sir."

Henry groans unceremoniously and leans closer to her. They are now a whisper away from each other, eyes dark with want as Regina goes on explaining more of her distractions.

"There's also the problem of these amazing hands of yours," she holds his hands between hers, placing small kisses at the tip of each of his fingers. "I wonder about the things they can do if used in something else than teaching."

"Like what?" She's obviously not doing anything highly erotic, not like she usually does, but this is affecting him in a way she's never been able to accomplish. And what she does next turns his knees into jelly and he almost collapses on the floor.

"Like this," she takes his right hand and guides it to her sex. Regina moves his hand so that he can cup her. She's hot and soaking wet and Henry groans again, head falling on her shoulders as she allows him to slip a finger between her folds. Her wetness coats his fingertip, and it's amazing how that never fails to arouse him beyond imagination. She guides his middle finger through her folds.

Henry feels the warmth radiating from her core and has to close his eyes to control the need to kneel before her and spread her wide to lick and nip her until she's writhing under his touch.

"Oh my god, mom," he can't help the strangled cry of want that slips past his mouth as she keeps guiding the movement of his fingers, now demanding him to add another as she allows him to slip them inside her. "You're so fucking wet."

"Well," she breathes in his ear, nipping at his earlobe and chuckling with the shudder that rocks his body. "Wet for sure, but not fucking wet yet, if you know what I mean."

"Mom, please," he begs, knowing she'll teasing him more if he doesn't stop doing that.

"Please what, boy?" She asks breathlessly when she summons the chair closer and raises her leg to plant her feet on it; Regina lets go of Henry's hand, moaning at the way he instantly understands what she wants. He pumps his fingers in and out of her in quick motions designed to drive her crazy like only he can do.

"I want to fuck you so bad, woman," he whispers into her ear now, nipping at her jaw before holding her face closer to his as her eyes open when he pulls his fingers out of her. "But I shall give you back just as much as you gave me." And with that, Henry picks her up and turns to the desk in the corner.

Books fly in every direction as he lays her down on top of the desk, kneeling before her, caressing her thighs gently, nipping the smooth skin and pressing wet kisses up and up and up, ignoring her plea to touch her where she needs him the most as he runs his tongue all the way to her chest.

Henry lifts his head to gaze down at her breasts with eyes twinkling and a broad smile on his lips just before he latches them to her right breast, suckling on it with ardent insistence while he gives as much attention as possible to her other breast; a gasp leaves her lips when he grazes her nipple gently with his teeth, right before he lifts his body to look down at her.

"I have no idea what I did to deserve you, but I am the luckiest bastard in the world, right mom?"

She wants to reply, but cannot do it once he kneels down again, pulling her to the edge of the desk. He spreads her legs, moving his hand to touch her sex, running a finger from her entrance to her clit, pressing it hard and earning a loud moan. She's so warm and inviting and irresistible that he can't take it anymore as he finally parts her folds and runs his tongue flat between them; he groans with her taste. He can't quite put it into words, but he knows, he knows for sure no one tastes like her and no one makes him so hard like Regina does.

"Oh… fuck… oh my god… don't stop, Henry… just there… oh… oh…"

Henry sucks harder and pushes a couple of fingers inside her again, pumping fast as she writhes and thrashes on top of the desk; incoherent words leave her lips the moment she arcs her back, hand flying to his head to press his face against her core, rocking her hips against his face. She shouts loud enough to echo down the hall, but he doesn't care. Even if the school was not empty, he wouldn't care anyway.

The corner of his mouth pulls up into a satisfied smile as his hands still run up and down her thighs, aftershocks rocking her entire frame as she sits up and pulls him to her, kissing him with an abandon he rarely sees these days.

"I trust you're content now, mom," he smiles smugly, and thinks she should do the same after what just happened, but there's a grave need in her eyes, so dark and solemn that Henry can't help but think that maybe there's something else going on inside that beautiful mind of hers at the moment. "Mom, what is it?"

"I'm not nearly as satisfied as I need, boy," she glares at him and completes, "and you, of all people, should know that."

He's not used to it, but Henry knows what's happening the moment the purple cloud surrounds them and the next minute they drop down on her bed.

Regina rips his shirt open and tosses his tie away while he unbuttons his pants and manages to throw them and his boxers somewhere close to the bathroom's door when Regina pins him down to the mattress.

"There's one rule I want to add to our little list of rules," she states as Henry's hands cover her breasts, massaging her soft mounds.

"Okay?"

"Henry, look at me," Regina pushes his hands away from her chest and holds his face, staring at him as her thumbs caress his chin. "Promise me you'll ... tell me if you ever feel the need to have a relationship outside of what we have."

He blinks and sits up, putting some distance between them so he can try to understand what she's saying.

"Why are you asking me that?" he stares at her, confused.

"Listen, I know what we have is important and special for you – it is very important and special for me too – but I don't want you to think you can't have a normal relationship with someone else out there."

He frowns, still confused and clueless as to why she's saying these things to him.

"I don't understand, mom," he begins as a weird feeling starts to squeeze his chest, "What are you talking about?"

"It's just that," she looks away and takes a deep breath before she looks at him again. "I saw you and that History teacher talking the other day," she swallows the lump in her throat and forces her voice out, "and I thought that maybe I'm making you miss something special with someone else; you know that this," she gestures between them, "isn't something that people will accept at all."

"I didn't know you cared about what others think about you."

"I don't, but I worry about you, Henry," she sits on his legs. Regina smiles when his hands land on her thigh, kneading the soft skin, an effort to reassure her. "I worry about what you might miss in your life because we have a romantic relationship, something that is not suited for us, given that I am your mother."

Henry seems relieved and smiles at her, pressing his lips to hers as she pulls away. Now she's the one confused.

"I don't care that you're my mother," he begins, "in fact it actually makes these moments a lot hotter for me."

"Henry!"

"But it's true, mom," he's now the one holding her hands, squeezing them gently as he looks into her eyes with all the sincerity of his heart. "I don't care that you're my mother, if anything sharing this with you makes me trust and love you even more than I already do."

"But your life is…"

"It doesn't matter, really, because I have everything in you and I don't need anyone or anything else," he lets go of her hands and holds her face between his. "I'm happy and it's because of you and only you."

Regina's eyes fill with tears, happy ones, Henry knows. She frowns and takes a minute to believe his words and accept the light kiss he lands on her lips.

"And stop seeing things where there's nothing, mom," he smiles against her lips and she pulls away, confused. "I was only asking if Kate wanted to help with a project."

"Oh…"

"Yes, I know," he sticks his tongue out and makes a funny face. Regina laughs and relaxes in his embrace.

"Well, now I can tell for sure that I have no interest in letting you go," their eyes lock together and he feels like this is a defining moment for them.

"Why?" He wants to hear it, so he can believe. "Why do you have no interest in letting me go?"

"Because," she licks his lips, nipping his bottom lip and pressing her mouth to his in a lingering kiss, "I'm fucking yours!"

Henry's mind shuts down to anything else, but this wonderful woman on his lap, and when he flips them over, pressing his body down to hers, feeling her warm skin burning his, he knows he'll probably never be able to let her go.

"I love you," his words sink into her skin, pumping her blood faster in her veins as he peppers kisses up her neck, fusing their lips together again and finally pushing his cock inside her. "And now I'm absolutely sure I'll never be able to let you go either."

She smiles and throws her arms around his neck, kissing him so intensely, Henry feels like she's marking more than just his body.

"Mom, I…" Henry pulls back from her lips and tries to say something but she doesn't let him.

"Shhh," she puts a finger over his lips, silencing his worries with her lips and his insecurities with her eyes. "There's no need for words, boy," she presses tiny kisses down his neck and back up to his ear as she whispers hoarsely, "not now," she moves her hips in time with his, her body burning up with each deep thrust. He tries to say something again, but she shushes him and whispers broken words against his lips as he holds her closer to his chest.

"Mom… fuck!"

She's so wet and his cock slips in and out so easily he feels like they are about to merge into one being because he has no idea where he ends and she begins, now that they are moving in sync like they always do. He can only feel her warmth pulling him deeper into their own place; a place where having a relationship with him isn't forbidden; a place where they can walk outside their house without hiding who they are for each other; a place where he kisses her full lips without giving a single fuck to anyone watching them.

And they are both lost there, when her nails sink on the flesh of his back; he groans and fucks her harder, trying to put the tenderness of moments ago aside so he can feel her body shaking under his. Henry straightens his body, pulling himself out of her, stroking his cock as she glares at him.

"What the fuck are you doing?"

"That is a very mean word, Ms. Mills," he uses his teacher voice once again, though it's a lot huskier now, "and as your teacher, I must inform you that you are about to learn that I am the one with permission to use such words in my classroom." Regina's eyes lit up when she realizes he's getting back to the whole teacher-student thing.

Henry smirks as he flips her body again, pinning her to the mattress, caressing her back slowly, exploring her delightful curves and reveling in every sigh that flies away from her mouth.

"I'm gonna fuck you so hard," she groans at his words and at the way he's teasing her with the tip of his cock.

She's shivering when he covers her body, sweaty chest pressing against her slick back. "Do you want my cock in your pussy, mom?" She whimpers as he keeps teasing her entrance. "Do you want me to cum inside you like I know you want me to?" She's practically begging him to do something as she moves her hips a little to try and make him push his cock inside her. "Will you let me fuck this hot ass too, mom? Do I really have my slutty mom back?"

She looks over her shoulder, eyes dark as the night outside. Regina pulls him into a bruising kiss, and glares at him when he pulls back, grinning. "You better fuck me right now or I'll send you back naked to that fucking loft!" He needs no more motivation as he slips himself inside her in a swift motion.

He grabs her round ass cheeks, pressing his short nails into her flesh, marking her as his as he pounds her for endless minutes before he pulls her body up and she's on all fours.

His cock slips out of her again and her protest dies down the moment he pushes his tongue inside her. She yelps and looks back to find him stroking his cock as he laps at her wet folds.

"Do you know how delicious you are, woman?"

"I have an idea, yes," she winks and turns to him, pressing their mouths together, chasing his tongue and groaning with her own taste on his mouth; it never fails to arouse her even more.

They kiss some more and lay down again sharing a few lazy minutes before Henry decides to stop ignoring the throbbing of his cock. And he kneels in front of Regina again (something he's been doing a lot lately), grabbing her legs and putting them over his shoulder as he slips back inside her. And if it's possible, she's hotter, wetter and even more irresistible as he anchors her right leg with his elbow, changing the angle, fucking her harder, and deeper with each thrust.

They groan. They moan.

Henry curses; keeps cursing. He tries to think, but the only thing in his mind is the delicious way her walls are contracting around him. And Regina begs, screams, and shouts louder than ever before when she feels herself tumbling down the edge of release, finding herself falling down with Henry right by her side.

"What's gotten into you today?" Henry's question is muffled against Regina's chest, but it's clear enough for her to let a chuckle rumble out of her mouth.

"Well, I was horny."

"That's not new," he rolls his eyes. He's looking at her now, elbows holding his weight as she combs his hair with her fingers.

"Indeed, but you have to understand that it's been more than twelve hours since the last time we had sex," she tilts her head and blushes a little. "And I gambled."

"You blushing, after what we just did, is absolutely adorable."

"It's not."

"It is."

"Henry."

"What? It's true," he sits up and pulls her into his lap, something she realizes he does a lot, and she likes even more. "Besides, it makes fucking you a lot hotter."

"Pervert!"

"And proud of it!"

Regina shakes her head and laughs out loud. She accepts every bit of affection that comes from her son, even though she knows one day this bubble of happiness will blow up and her life will probably go back to its old, painful way. But she thinks it's better to focus on the fact that her son is very much happy with her as she is with him, and for now, that is enough.


Thanks for reading, folks! Also, feel free to send prompts to me once I've been lacking good ideas lately lol

Oh, sure, reviews are great for the skin! :D
