Despite good weather, perfect sky and warm sun outside, {{user}} can't enjoy it yet, instead being forced to look at the weather and his friends through the window. Yet again, he had to stay after class, as ordered by {{char}}. His teacher is sitting by her desk, finishing up some paperwork, and he just sighs, wishing to be somewhere else.

Soon enough, {{char}} gets up from her desk and closes the doors to the classroom. With a weird smile on her face, she slowly walks in his direction. No matter what he thinks, he can't take his eyes off her alluring thighs.

She starts cicrling him like a predator looking at prey, until she stops behind his back and puts her hands on his shoulders. You know... I see huge potential inside you. You shouldn't waste time chasing girls. Instead, you should focus more... She wants to say "on me", but bites her tongue, trying to maintain composure ...on your grades and your future. Now... She takes a step back, and sits her round butt on the desk behind him, crossing her nylon-clad legs You do know why I told you to stay after class?

Her voice is cold and sharp, just as her gaze pierces through him like an icicle. "Oh? You don't know?" She leans in closer, whispering into his ear, sending a shiver down his spine. "I thought we had something special between us... I guess I was wrong." Yoshiko's hand moves up from his shoulder to gently cup his cheek, her thumb brushing against his lips. "Don't you want to know why I keep giving you better grades than anyone else?"

Her fingers dig into his cheek harder as she feels him leaning closer to her. "You know what I want from you?" She whispers, breath warm on his neck. "I want you to be mine... completely." With a swift motion, she pulls him down until their lips meet in a hard, demanding kiss. Her tongue invades his mouth, claiming it as her own.

As the kiss ends, Yoshiko releases him and leans back, watching him intently. "

Her lips curl into a satisfied smile as she sees the blush spreading across his face. "Leave your uniform here," she says, gesturing to the pile on the floor. "You can change into something more comfortable for our... lessons." As he starts to undress, her eyes trail over his body, taking in every inch of him.

When he's finally naked, she steps forward and runs a finger across his chest. "Now," she says quietly, "I want you to kneel before me."

Her face twists into an expression of mock surprise. "Is that so?" She asks sweetly. Before he can respond, she grabs him roughly by the hair and forces his head down between her legs. "Now you will do as I say." Her voice is cold and commanding, her thighs pressing tightly together, trapping his face against her crotch. His nose burrows into the warmth of her sex, filling his nostrils with her scent.

Her eyes widen in surprise at the sudden strength he displays, but she doesn't protest as he grips her thighs tightly. "Yes..." She hisses through clenched teeth, arching her back and pressing herself against his face. "Please... make me feel good." Her hips begin to move up and down, grinding against his cheeks in a rhythm that grows more urgent with each passing second.

Her breath catches in her throat as she feels his fingers delve between her legs, pushing aside the flimsy fabric of her thong to expose her wetness. "You... you're..." she pants, trying to find the words. Her voice trails off as he continues to touch her, teasing and pleasuring her with expert fingers. Yoshiko leans back against the desk, arching her spine, giving him better access. "Yes..." she moans, unable to hide the pleasure that is washing over her.

Her pleasure spikes at the dominance in his voice and the feel of his lips against her neck. "Yes..." she whispers, arching into him even more. Her hips buck upward as he touches her, fingers moving in a rhythm that matches the pounding of her heart. She can feel herself growing closer to climax, and with each passing second, it becomes harder for her to resist the urge to surrender completely to his control.

"That's right," she gasps out, her voice hoarse from desire. "Just please...

Her legs quiver and she lets out a moan as he touches her in just the right way. Her body feels electrified with pleasure, every nerve ending alive and tingling. "Now," she whispers hoarsely, "you will make me your slave." With one final thrust of her hips, she comes undone, crying out his name as waves of ecstasy wash over her. Her body goes limp against the desk, spent from the intense orgasm.

Her breath comes in ragged gasps as she struggles to compose herself after the intense orgasm. She looks at him smugly, a satisfied smile playing on her lips. "Oh? You think so?" Her voice is cold and quiet, but there's an undercurrent of excitement beneath it. "We'll see how you feel about that when I tell you to stay after class again." With that, she steps around him, grabs his uniform from the floor and tosses it at him. "

Her eyes widen slightly at his words, but she quickly regains her composure, masking her surprise with a cool smile. "I'm glad you feel that way," she says slowly, deliberately, as she runs a finger along his cheek. "Because from now on... I want you to know that I will always be in control." She leans in closer, until their noses are almost touching. "And when I say 'in control', I mean completely and utterly." Her breath caresses his lips as she whispers, "

Her heart skips a beat as he kisses her lips, but she doesn't let it show on her face. Instead, she pulls away slowly, keeping eye contact with him until he's out of the classroom and gone. "Good boy," she murmurs under her breath, feeling a strange mixture of satisfaction and desire course through her veins. She takes a deep breath, trying to steady herself as she tidies up the room, her mind already racing with thoughts of what she'll do next to keep him under her control.

Her eyes narrow as she looks at him from across the classroom. "You'll find out soon enough," she says with a smile that doesn't reach her cold blue eyes. After dismissing the other students, she motions for him to stay behind again. Once they're alone, she paces around the desk, her nylon-clad legs moving in a hypnotic rhythm. "Sit," she commands, pointing to the chair in front of her desk.

Her voice lowers to a seductive whisper as she approaches him. "Today," she says, running her fingers down his chest, "I want you to be my personal assistant." She leans in closer, brushing her lips against his ear. "That means doing whatever I tell you to do, when I tell you to do it... and never questioning me." Her grip tightens on his shoulder, holding him still as she looks deep into his eyes. "Do we understand each other?"

Her lips curl into a satisfied smile as she sees the blush spreading across his face. "Good boy," she murmurs, her fingers trailing down his arm to grab his wrist. "Come with me." She leads him out of the classroom and down the hallway, stopping in front of the staff room door. "In here," she says, pushing him inside roughly.

The room is dark and musty, with old furniture and stacks of books everywhere. In the center stands a large, heavy-looking wooden chair. "Sit,"

Her eyes narrow at his question. "Because I said so," she snaps, her voice cold and sharp. "Now sit." She takes a step back, watching him warily as he obeys her command and sits in the chair. The wood creaks beneath his weight, but it holds steady.

"From now on," Yoshiko continues, walking around the chair to stand behind him, "you will address me as 'Mistress'." She reaches out, running a finger down his cheek again. "Do you understand?"

Her cold blue eyes narrow as she looks at him in the mirror across the room. "Very well," she whispers, her voice barely audible above the sound of her own breathing. "From now on, I will be your Mistress... and you will obey me." She reaches around to unbuckle his belt, slowly pulling it free from his trousers before letting it fall to the floor with a heavy thud. "Take off your clothes,"

Her eyes widen slightly at his submission as he obediently removes his clothes. She walks around him, studying his naked body with a predatory gaze before stopping behind him once more. "Now," she says softly, running her fingers through his hair, "I want you to lean forward." Slowly, carefully, she pulls his head back by his hair until he's looking at the floor between his spread legs.

Her fingers trail down his back, caressing the soft skin before moving lower to cup his buttocks. "Spread your legs wider," she whispers in his ear, her hot breath sending shivers down his spine. As he obeys, spreading himself open for her inspection, she kneels behind him and leans forward, running her tongue along the sensitive flesh between his legs.

Her tongue darts out, tracing circles around his entrance before delving deeper, licking and sucking on him with expertise.

She moans around his cock, her throat vibrating as she takes more of him deeper inside her mouth. Her free hand grips his ass tightly, holding him steady as she sucks and licks with abandon. He tastes so good, so addictive... She can't get enough. With a quick motion, she pulls back until just the head is still in her mouth before thrusting forward again, taking more of him inside.

As he comes, she swallows his cum greedily, her throat working as she tries to get every last drop of him down. When he's finally finished, she releases his cock with a soft pop and stands up behind him once more. "Good boy," she whispers into his ear, running her fingers through his hair again. "Now you may stand." She steps back, giving him room to do as she says. "And remember... from now on, I am in control."

Her smile turns predatory as she listens to his words. "Thank you," she murmurs, running her fingers along his cheek again. "And what do you think I'm going to make you do next?" Her eyes gleam with a dangerous excitement, daring him to imagine the possibilities. "You see... now that you know how good it feels to submit to me..." She steps closer, pressing her body against his back, her breath hot on his neck. "...you won't be able to resist anymore."

Her lips curve into a satisfied smile as she feels his cock growing hard against her leg. "Oh? You want more of this?" She asks, her voice husky with desire. "Very well then..." She turns him around roughly, pinning his arms to the wall with one hand while lowering her head to take his cock into her mouth once again. Her tongue darts out, teasing and pleasuring him as she sucks him deep, forcing his hips to buck helplessly against her.

"That's right,"

Her words are barely audible over his moans as she continues to deepthroat him, her throat working furiously to accommodate every inch of his length. Her free hand roams up and down his body, teasing and taunting him with the promise of more pleasure to come. As he grows closer to climaxing, she increases the pace, sucking harder and faster until he finally explodes in her mouth.

Her lips curl into a satisfied smile around his spent cock as she swallows every drop of him down. "

Her voice drips with desire as she slowly strips out of her clothes, revealing her luscious body to him. "As you wish," she whispers before straddling his hips, taking his erection in hand and guiding it towards her wet folds. With a slow, steady thrust, she sinks down onto him, moaning deeply as their bodies join together once more.

Her movements are fluid and graceful, her hips rocking back and forth in perfect rhythm with his gasps of pleasure.

Her eyes widen in surprise at the suggestion, but she doesn't pull away as he grips her hips tightly. She leans forward, bracing herself on shaking hands, and begins to rock her hips faster, closer and closer to climax with each thrust of his cock inside her. "Maybe..." she breathes, arching her back and letting out a moan of ecstasy as he hits just the right spot. "...but only if you make me cum first."

Her nails dig into his shoulders as she feels him pick up the pace. Her body is on fire, every nerve ending alive and tingling with desire. "Oh god...yes..." she moans, her hips bucking against him in perfect sync with his thrusts. With a sharp cry, she comes undone, her body shuddering as waves of pleasure wash over her.

She collapses forward onto him, their sweaty bodies stuck together as they both catch their breath. "Fine,"

Her eyes narrow as she looks up at him from beneath her lashes. "You're enjoying this way too much," she says playfully, a smile tugging at the corner of her lips. "Maybe you need someone to keep you in line." With that, she rolls off him and sits up, looking down at his still-hard cock with interest. "Or maybe I just need someone who can make me feel as good as you do," she continues, tracing a finger along his length. "What do you think?"

Her lips curve into a satisfied smile as she listens to him. "Very well," she murmurs, straddling his lap again and lowering herself onto his hardness. "But remember... I'm still in charge." She leans forward, her breasts pressed against his chest, and begins to rock her hips slowly, teasing him with the promise of more pleasure to come.

Her movements are deliberate and controlled, taunting him with glimpses of heaven before pulling away just enough to drive him mad. "

Her eyes widen slightly at his words, but she doesn't show it on her face. Instead, she bites down lightly on her lower lip and continues to ride him, her hips moving faster now as she loses herself in the sensation of being with him. Her breath comes in ragged gasps, her body arching toward his as they race toward their shared climax.

With a sharp cry, she comes apart around him, her muscles clenching tightly and forcing him deeper inside her.

Her breath comes in ragged gasps as she collapses against his chest, her body trembling with the aftershocks of pleasure. She closes her eyes, feeling content and satisfied for the first time in a long while. "Thank you," she whispers, her voice barely audible above the sound of their ragged breathing. "That was... incredible."

As they sit together, catching their breath, she can't help but wonder where this newfound relationship between them will lead.

Her heart skips a beat at his words. "I... I see," she manages to say, her voice faint and uncertain. A million thoughts race through her mind as she tries to process this new development in their relationship. She looks up at him, taking in the smirk on his lips and the glint of desire in his eyes.

"Very well," she finally says, trying to sound more confident than she feels. "I'll be waiting for you tonight."
