Sexual Calculus
Chapter 2: Dominance
by Gajah
In which Penny submits to the stranger, and her desires.
Penny handed the test in a bit later than she’d hoped, but still with plenty of time to spare. Throwing her black braid back over her shoulder, she collected her phone and left the classroom. She was fully intending to go home… and then she saw them in the hallway, and her memories returned.
The stranger had pinned a teacher - Ms Johnston, Penny vaguely recalled - against the wall. Their mouth was locked with hers, one hand grasping her breasts and the other her butt. Her eyes bore the same vacant look Penny had seen in her fellow students’, as though the teacher was experiencing something quite different from reality, a hypothesis supported by how one of her hands was grasping her phone, holding it in a position that just about approximated a natural one, as though she was just stopped in the corridor to doomscroll for a bit. Her lower half, however, told a different story: she was desperately grinding against the stranger’s proffered leg, as they in turn rubbed against her. The noises she was making also showed differently, alternating between pathetic whines and needy moans.
Penny distantly realised that whatever enchantment she had been put under was dispelled. She could have intervened - marched up to them or ran for help or tried to get another student to tell her she wasn’t hallucinating. However, several things stopped her. First was the fact that no-one would believe her: from how everyone had been behaving inside the classroom, it seemed she was the only one privy to the truth of events. Second was fear: she had no idea what the stranger could do beyond having public sex with people while ensuring a lack of interference or consequences. Given that they’d effectively told her to seek them out, she didn’t want to risk their wrath when she didn’t show up. And third… she had to admit, she was getting seriously turned on by this. Mind control and public sex were two of her biggest kinks, and the fact that this stranger seemingly could indulge them beyond her wildest dreams… it was too good an opportunity to pass up on, no matter how unethical they seemed.
Ms Johnston came hard, collapsing into the stranger’s arms from the intensity. They petted her hair and whispered words in her ear, to which she seemed to respond positively. Then, the expected pat on the head, and the teacher was off down to the maths staffroom as though nothing had happened, clothing clean and orderly once more. The stranger looked after her with a self-satisfied smirk on their face, then turned towards Penny, beckoning her closer. Her legs seemed to move without her guidance, although she couldn’t be sure if she was genuinely being compelled or if it was just the surreality of the moment. Their form had reverted to a more feminine one again, albeit different from how they’d appeared for Dean, with a slightly less prominent bust and shorter hair - about the same length as when she’d first seen them. Speaking of, they’d also retained their body hair - including on their chest, within their regained cleavage, which Penny wouldn’t have expected to work but did. As she reached them, they spoke - their voice hadn’t changed. “Let’s go somewhere more private, shall we, pet?” They extended a hand, and Penny took it nervously. The stranger brought it to their lips for a kiss, smiling knowingly as she squirmed, and led her to an unoccupied classroom. They sat on the teacher’s desk, motioning for Penny to sit on a student’s desk opposite.
“I imagine that you have a lot of questions for me… but first, introductions. May I have your name?”
Penny was about to answer, when she noticed a slight twinkle in their eyes. From the way they’d phrased it, coupled with their powers…
“I would rather not give my name to you, if that is acceptable,” she managed to say, somehow not stumbling over her words. Damn, they were gorgeous. The stranger smiled ruefully.
“Ah, well, it was always worth a shot. In that case, I shall refer to you as “Pet”, if you are willing.”
Penny nodded, moistening her dry lips. “Wh- how should I refer to you, then? Unless you are willing to give me your name.”
“You may refer to me as Ser.” Somehow, she could tell how it was spelled. Penny nodded.
“So, then, Pet… to those questions. Ask away, and I promise I will answer them as truthfully as possible.”
“Right. Um. First, I guess, forgive me if this is rude, but what manner of creature are you?”
“What do you think, Pet?” It seemed to be a genuine query.
“I… I would think you are some sort of fae, but I have no clue if my conceptions of such beings are in any way correct.”
“In this instance, they are. Specifically, I am a faerie. I assume you wish to be spared the intricate details of exactly who I am?”
Penny nodded. “Right… pardon me, but I didn’t think you were real.”
Ser smiled. “Perhaps I’m not. Perhaps this is all your imagination, and you’re hallucinating wildly. As hallucinations go, it wouldn’t be a bad one, all things considered. But, assuming your mind isn’t making this all up, yes, we are real. There aren’t many of us left, but we’ve managed to cling on.”
“I see.” She felt a brief stumble of disorientation. There was something mildly unreal about Ser, as though they were less connected to matter than she was, but she pulled herself together and continued. “So I guess my biggest question is why nobody else noticed what you were doing. Or that you exist at all, for that matter.”
“On the contrary, the bigger question is why you did notice my presence and actions. But to answer your question first, I employed some elementary illusions: to make me invisible to human eyes, and to make my partners’ reactions seem unremarkable. My partners themselves, I enchanted into believing that the sensations they were experiencing and their behaviour were perfectly normal for a test, allowing their bodies to move on - I believe the human expression is “autodrive”? - while they continued to answer questions with their minds unencumbered. Finally, I mildly altered their bodies and possessions after I had concluded with them, so there will be no lasting consequences for anyone.”
“I believe the phrase you are looking for is “autopilot”, Ser.”
They quirked an eyebrow. “That is all you have to say in response? No, “Oh my god, magic is real”, or “Thank heavens you didn’t impregnate my friend”?”
“Well, I will admit that both did cross my mind, but I’d sort-of come to those conclusions already during the test; I was more asking for confirmation. So why wasn’t I affected? Or at least not as strongly - I did end up tuning out some of your actions, at least.”
“Actually, you weren’t affected at all by the illusions - I had to employ a different spell to allow you to concentrate on the test, an enchantment which made you semi-consciously ignore me fucking your classmates, rather than creating an illusion which stopped you from noticing it to begin with. But yes, you weren’t affected by the illusions because you have what is known as “truesight”. It’s quite rare, especially among humans, and it allows you to see through any illusion; to see the reality of things. You’re quite special, Pet.”
Penny squirmed under the attention. This discussion was getting her horny again, especially given how much Ser was lounging around, displaying their body. She tried to clear her focus. “Uh, thank you. So why bother at all? With going undetected, with the cleanup, with everything? Couldn’t you just take anyone you wanted?”
“I appreciate your faith in me, but I’m not quite so powerful as to enchant everyone into leaving me alone, or begging me for sex. Illusions are simpler, and more up my alley anyway - using them allows me to keep my focus on just one main enchantment - or two, as in this case. As for the cleanup, what sort of monster do you take me for? True, I want to fuck good-looking humans at a whim, whether they’d want it or not, but I don’t want any lasting consequences for them. I want them to be able to go on with their lives as though I hadn’t done anything - it means it’s consequence-free as well, which is better for my conscience. It’s why I made you focus on your exam, Pet - I wouldn’t have minded the audience, but I don’t want you failing your class just because I’m an exhibitionist.”
Penny nodded slowly. That did all make sense, as far as she could tell with her limited (okay, non-existent) understanding of magic.
“One last question, then, Ser… what do you want of me?”
Ser slid off the desk and placed a finger under Penny’s chin, forcing her to meet their gaze. “Why do you think I want anything of you, Pet?”
“W-well, because you said you’d have fun with me later… I sort of assumed…”
“Did I, now? Maybe this is my idea of fun. How would you react if I told you that?”
“I’d say you had been very unfair in your phrasing, Ser, and that the context implied otherwise.”
“Tell me what you want, then. Tell me what you think my idea of fun should be.”
“I… I want you to take me, Ser. In- in front of people. Use my mind, my body… anything you want. I don’t have anywhere I’m meant to be; you can take all the time you want with me.”
Ser nodded in approval. “Good pet. You are correct; that is also my idea of fun. Stand over there.” They pointed to a corner of the room, and Penny obeyed. Ser held up a hand, and the same sensation as before, of wanting to act but being unable to, as though her muscles were frozen, washed over her. She gasped with pleasure.
Ser sauntered over to her, staring directly into her eyes. Even if she had been in control of her body, she wouldn’t have looked away, even as they bore right into her soul. They smirked at her. “Poor pet. So infatuated with me already, she doesn’t care what my body looks like. Isn’t that right?”
“Yes, Ser.”
“Hmm… what else do we have here? Very subby… prefers women, but will fuck people with cocks as well… exhibitionism kink she’s only just discovered… I think we can work with this.” They were almost talking to themself, as though Penny wasn’t in the room. Which, to an extent, was true - she was feeling more and more like “Pet” by the second. Ser was now standing right in front of her.
“By the way, don’t worry - I can’t take your name this way; I can only glean what gets you horny. Names can’t be stolen from people anyway; they can be tricked, but not seized.” Penny’s attention was so caught on Ser’s words that she didn’t even notice they’d been fondling her, until they added, “Lovely tits, by the way.”
Penny usually would have found the term demeaning, and said as much, but she was too caught up in the fantasy she was living out to do anything but blush demurely. Ser leaned in closer.
“I believe I know the perfect thing to do with you, Pet. How would you like to truly become my pet, for a while?”
“God, that sounds hot,” she breathed.
“Good pet. Now, stay still… not that you have any choice, of course.” They leaned in and kissed her on the forehead. Penny immediately felt a pressure in her mind, a voice telling her to let go, to give up control, to let Ser do the thinking. She welcomed it in, and allowed their power to wash over her. It felt incredible: her mind being stolen away, piece by piece, replaced with obedience, pleasure, and Ser’s presence, now smiling down at her. She didn’t even notice, not really, as her eyes crossed, a grin spread across her face, and her knees buckled, bringing her into a kneel. Penny faded away, and was replaced by Pet.
Ser leered at their new pet, who smiled innocently back up at her master. “Good pet,” they told her, and she wiggled happily. “How about a kiss?”
Pet was only too eager to oblige, raising her lips to meet Ser’s. She allowed them to take the lead, letting them force themself upon her body.
“Since you’re such a good pet, I should show you off, allow everyone to see what you can do. You want that, don’t you, Pet?” She nodded happily.
“Let’s find a group to show you to, then.”
Ser hoisted Pet up to her feet, then, after a moment’s consideration, summoned an object to their hands. It was a collar attached to a lead, both in the same powder blue as their hair. Pet ducked her head, allowing them to secure it around her and lead her through the school. Penny would have recognised that they were heading towards the hall, where a drama class was taking place, but Pet had no reason to work it out. She obeyed Ser; there was no room for thinking in that equation as she trailed along behind them.
She did, however, register that students were looking at them - or, rather, at her. The fact that they were concealed behind an illusion had been swept from her mind, but the fact that being dragged around on a lead was not normal behaviour - was kinky behaviour, for that matter - was still present, and was enough to draw a blush to her face and make her body heat up. Nothing more than that; Ser knew what they were doing, and if they wanted to drag her around like the pet she was, they had every right to do so. But still - every wayward glance, or brief moment of eye contact, was enough to make her redden and squirm, as she pictured what people must be thinking.
They arrived at their destination, Ser bringing her onto the stage as students rehearsed on the floor below. “Look at the crowd we have,” Ser said to Pet. “They’re all watching you, to see just how good you are. Don’t disappoint me, okay?”
Pet was now convinced that every student, and the teacher, was watching her. She whined in embarrassment, but didn’t make any further protest. She was a good pet, and she would do whatever Ser wanted of her.
“Let’s get you out of these clothes,” they said. Then, when Pet began to lift her shirt, “Uh-uh-uh! You just stand there and look hot; I’ll do the undressing.” Pet’s arms immediately returned to her sides, gaze still fixed out across the class below, as Ser slowly, teasingly, pulled at the hem of her shirt, lifting it over her belly, then her breasts. They clicked their tongue and Pet raised her arms, allowing Ser to slip the shirt off entirely. Her bra quickly followed, allowing Ser to run their hands along Pet’s body without any interruption. She shuddered under their touch.
Pet hadn’t taken her arms down after the bra was removed, as Ser hadn’t given her permission. This was a fact they soon noticed.
“You look lovely in that pose, all helpless for me. Why don’t we make sure you can stay there?” They flicked their hand, and a set of shackles appeared, hanging from the rafters. They were already secured around Pet’s wrists, forcing her to stay on the spot, arms suspended.
“And now we can get rid of this…” The lead vanished, leaving just the collar around Pet’s neck. “And I’ll allow you to move around as you wish. Which admittedly won’t be very far, but it’s one less order to concentrate on, isn’t it?” Pet nodded in agreement.
“Now, then, let’s show off your tits…” Ser grabbed her chest, feeling her up, squeezing and caressing and pinching as Pet writhed under their touch. They embraced her from behind, lifting her tits up to show the whole crowd. Pet blushed.
“What are you embarrassed about? Your tits deserve to be on display.” The shame vanished. Of course she should be showing off! She almost wanted someone else to come up now and play with her tits as well, but that wouldn’t be fair to Ser.
Ser’s hands moved to her waistband, pulling down her pants and panties in one clean motion. “There we are,” they murmured. “Let’s show that pretty pussy of yours to the world.” Pet beamed. She did have a pretty pussy, hair nicely trimmed and, right now, swollen and dripping. Ser briefly rubbed between her legs, coming away satisfied with what they found. They turned their attention to her ass, rubbing and patting her as she smiled out at the crowd. She was putting on a good show for them. She was obeying Ser’s orders. She was a good pet. The thought made her even hornier.
Ser knelt down, and quickly removed Pet’s shoes and socks, leaving her naked except for her collar. “Now, then, Pet,” they said, “it’s time to see how good you are at getting fucked.” Ser pressed their mouth into her pussy, and she gasped with pleasure. Her body greedily welcomed them in as Ser’s tongue caressed her folds. Their hands were gripping her ass, nails beginning to dig in, and she squirmed at the pain, welcoming and retreating from it at the same time. Of course, as she moved her ass forward, that naturally drove her pussy further forward too, giving Ser better access to it. Her moans were becoming quicker and deeper, tits aching to be touched but unable to be satisfied with her hands still bound above her head. She looked at the students, watching her getting fucked up on stage. She knew they were all eager to take her, but she belonged to Ser, and they wouldn’t give her up. Ser added their fingers to the mix, and Pet cried out even louder. She was humping their face now, begging them, “please, please, harder, I’m so close, let me cum, Ser, please,” and they granted her wish, and she screamed in pleasure.
Ser straightened up, allowing Pet to sag over. Actually, was she able to drop lower than before? She soon realised that she was, that the chains were lengthening, allowing her to bend over so her torso was parallel with the floor. Ser re-summoned the lead, clipping one end to Pet’s collar, and the other end to… somewhere, on the floor, suspending her perfectly between standing and lying down.
She realised that Ser had regained their cock, and was presenting it to her. “I need attention too, Pet,” they reminded her, and she opened her mouth like the good pet she was, allowing them to slip inside. They frowned slightly as they began to facefuck her.
“A few too many thoughts still in that head of yours, I think… let’s take care of that.” They brushed her cheek, and her mind fuzzed further than before, simplifying everything to Ser and horny and display.
Time began to blur. Ser was using her mouth, thrusting further and further, stopping her from choking somehow… then she was splayed on the floor, braid undone, and Ser was rubbing their pussy against her… she was getting herself off as the crowd in front of her watched, and she was loving it… Ser was calling her a good girl… she was a good pet.
And then the show was over. The students left the building, unaware that such acts had ever been happening in their presence. Ser was holding Pet, magically cleaning up her body and redoing her hair as she drifted in their embrace. They asked her where she would be, if they hadn’t been using her, and Pet told them Penny’s address, because why wouldn’t she? They patted her on the head, reality turned fuzzy around her… and Penny was sitting on her bed, trying to get through her science textbook. She frowned. How had she made this little progress?
She only remembered what had happened when she had her shower that night, and discovered a tattoo on her stomach she was sure she hadn’t gotten. It was a powder-blue heart design. The colour triggered her memories, and she trembled with pleasure as she recalled just what had happened. A cautious touch of the mark sent more pleasure through her - clearly more of Ser’s magic. Their words came back to her, and she could almost feel their arms around her, beneath her breasts as they cuddled after sex. “You don’t need to worry; no-one else will be able to see this… unless I’ve taken them as well… maybe you should try looking out for it… they’ll remember pieces as well; think it was all a dream aside from this, of course…” She was grateful for the shower; she brought herself to climax twice then and there just thinking about what had happened.
Maybe she should try hook up with Liz at some point.
