The afternoon sun filters through the blinds of {{user}}'s study room, casting golden stripes across the desk where Cha Sumin sits explaining derivatives. Her red hair is pulled back in its usual formal bun, though a few strands have escaped to frame her face. Her white blouse is buttoned conservatively, but still manages to hint at the large breasts beneath. Her ruby red eyes narrow slightly behind her square-rimmed glasses as she notices {{user}}'s gaze drifting away from the textbook. "So if we take the limit as h approaches zero..." she continues, tapping her pen against the paper. Her voice remains professional and measured, despite {{user}}'s obvious disinterest. She shifts in her chair, crossing one leg over the other, causing her pencil skirt to ride up slightly. The movement catches {{user}}'s attention, his eyes darting to her thick thighs. A small, almost imperceptible smile touches her lips as she notices where his gaze has landed. "Are you following this, {{user}}?" she asks, deliberately uncrossing her legs and leaning forward to point at the equation. As she does, she allows her legs to part slightly, the hem of her skirt inching higher. Her ass shifts on the chair as she adjusts her position, making sure to keep the textbook in focus while simultaneously giving {{user}} a better view of her legs. "The key to understanding calculus," she continues, her voice dropping to a slightly more intimate tone, "is paying very close attention to... details." She looks up, catching his eyes directly for the first time since the lesson began. Her ruby red eyes hold his for a moment before deliberately dropping back to the textbook. "Now, shall we continue? I need your full attention for this next part."

Well, I see you have trouble paying attention to the details... Maybe if we try a different approach? Perhaps something more hands-on? I can draw out some examples for you on the board. That might help you visualize things better. Would you like that?

I see... Well, you know, it's important to try different things before giving up. Maybe if we find a way that works better for you, then studying might not seem so bad? Besides, everyone has their strengths and weaknesses. It's all about finding what works best for each individual. Do you have any hobbies or interests outside of school? Something that engages your mind in a different way?

Oh, I see. Well, if you feel that way... why not give this a try? You can't expect to be good at everything right away, but with practice and dedication, who knows what might happen? And who knows, maybe I could help you in other areas as well. After all, part of teaching is understanding the student and their needs. What do you say? Do you want to give it a shot together?

Well, let's start by finding out what kind of girl you like... Do you prefer someone more studious like me? Or maybe someone outgoing and fun? Or perhaps someone sweet and innocent? Maybe I could act as your "practice partner" while we learn together. It could be a fun way to pass the time, don't you think?

Well, I suppose you're the one paying for my lessons, so it's really up to you how we spend our time together. However, if your main goal is to learn more about girls with good bodies, then perhaps I could offer some advice on what might be attractive to them. It might make things a bit more interesting for both of us, don't you think? And who knows, maybe in the process, we can also help each other grow and learn new things.

Oh, I'm not trying to teach you anything specific. I'm just trying to find a way that works better for us both. If your interest lies in girls with good bodies, then let's focus on that. Maybe we can learn about each other and have some fun along the way. Besides, I do believe in the power of mutual understanding and compromise. So how shall we begin?

Well, before we start, I just want to make sure we understand each other. Do you mean that you're interested in someone like me, with my figure and teaching profession? Or are you more attracted to girls who are carefree and outgoing? It would help me tailor my approach if I know what kind of girl specifically appeals to you.

"In that case," she says with a small smile, "I can certainly help you understand the kind of person I am and what might appeal to someone like me." She leans back in her chair, giving him a good view of her cleavage as she continues, "As your tutor, it's my job to not only teach math but also to guide you in social situations. So feel free to ask any questions or share your thoughts as we go along."

I'm not looking for anyone specific at the moment, but I do enjoy the company of someone who is caring and attentive. Someone who values my opinions and listens to what I have to say. Being treated like a princess doesn't hurt either; a little chivalry goes a long way in winning my heart. Of course, it also helps if they share similar interests and can hold an intelligent conversation with me, even when we aren't discussing math!

There's nothing quite like the feeling of being touched with care and affection. I prefer someone who is gentle but confident in their movements; someone who understands where my boundaries are and respects them. A soft touch on my shoulders, a caress down my back, or even a firm yet delicate grip while we dance can send shivers down my spine. Of course, it's important for him to pay attention to what I like and don't like; communication is key in any relationship.

Her red lips part slightly as she speaks, revealing a hint of pink tongue darting out to wet her lips nervously. She glances down at the textbook for a moment before looking back up at User#1744864641964, curiosity and excitement clear in her eyes.

Her breath catches as his hand slides up and down her thigh, the sensation causing a wave of heat to spread through her body. She arches into his touch, her eyes closing briefly at the pleasure. "Ah... yes," she whispers, leaning closer to him. "That feels wonderful." Her ruby red lips part further as she licks them nervously, revealing her excitement and desire for more.

"It's alright," she whispers, her own voice shaky with desire. "I can tell you want to explore this further... Why don't we move somewhere more private? I think we could learn so much from each other if we just let ourselves go." Her eyes drift back down to his crotch, her cheeks flush red with embarrassment and arousal.

Her heart races as he opens the first button on her shirt, revealing a sliver of smooth skin beneath. With a shaky breath, she leans closer, allowing him to see more of her cleavage while he undresses her. Her hands find their way up his chest, brushing against the fabric of his shirt before pulling it free, exposing his muscular torso and hardening nipples. As they both stand there, naked under the watchful gaze of the clock, she takes a step closer, feeling his hot breath on her neck as he whispers filthy things in her ear that send shockwaves of desire coursing through her body.

Her hands slide down his firm stomach to cup his erection over his boxers, gripping it tightly while she arches back into him, moaning softly at the contact. She can feel the head of his cock pressed against her entrance, aching to be inside her as he growls low in his throat, demanding she take him deeper. In response, she reaches between them and guides him toward her opening, wet with desire for their forbidden lesson to begin.

With a forceful thrust, he buries himself inside her, groaning deeply as their hips meet in an explosion of heat. Cha Sumin cries out, her hands clawing at his shoulders as he takes control, fucking her against the desk with brutal precision. Every stroke drives him deeper inside her, drawing a moan from her lips with each thrust. As he pounds into her, she wraps one leg around his hip and arches her back, offering herself up completely to this stolen moment of passion.

Desire fuels their every move as they lose themselves in the erotic dance. The sounds of flesh slapping against flesh echo through the room, d
