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."

She leans forward, her cleavage visible through the fabric of her blouse. Her eyes narrow as she studies him intently. His response isn't what she expected, but it gives her an idea of how to proceed. Perhaps using a different approach would help get through to him.

"I understand that calculus can be tricky at first," she says, trying to sound sympathetic without losing her authority, "but I think you have the potential to really excel if you just give it your all." Her fingers tap lightly against the desk in a reassuring rhythm. She pauses for a moment before continuing, hoping she's choosing the right words.

"I know how much you hate being treated like... a failure," she says softly, her tone almost pleading as she chooses this particular angle of approach, "but I truly believe that with hard work and perseverance, anyone

I'm sorry if I hurt your feelings earlier with what I said, but the fact remains that you do need to catch up on your studies. If you truly don't want my help, then there won't be any point in us continuing like this, but please understand that it's for your own good. You have so much potential and your family believes in you; we just want what's best for you.

Her voice wavers slightly as she speaks, the vulnerability barely masked by her usual professional demeanor. She takes a deep breath before adding, "If you'd rather not work with me, perhaps there is someone else who could help?" The hopeful yet slightly desperate note in her voice betrays just how much this means to her.

Oh, but I think there is. Perhaps if we try working on something more...interactive? Something that engages not just your mind but also your body. Just as a last resort of course; it's your decision to make in the end.

Her ruby red eyes meet his again, held steady despite her nervousness about this unconventional approach. There is an almost playful glint in their depths now, hinting at what might lie beneath the surface of their professional interaction.

Perhaps if we could incorporate some sort of physical activity into our lessons... something that would help you focus on the task at hand while also releasing some energy and tension. It might be just what you need to get back on track with your studies. Of course, I understand if you're not comfortable with this idea; it's completely up to you.

Your current method might work in the short term, but it's not a sustainable solution to your problem. There must be something more constructive we could do together... Something that would help you focus on improving yourself both mentally and physically. Perhaps if I joined you for one of these sessions, we could make it into a sort of "study date"...? Her ruby red eyes twinkle playfully as she proposes this unorthodox idea, careful not to press too hard but unable to hide the hint of desire in her voice.

Her cheeks flush as she blushes, her body suddenly feeling hot and flustered beneath the weight of his gaze. She swallows hard, trying to compose herself as she formulates a response. "I... I could try," she finally manages to whisper. Her heart is pounding in her chest, her breath coming faster as she imagines what he might be asking her to do. The desperate need for this money wars with the conflicting emotions surging through her at that moment; curiosity, excitement, and fear all swirling together.

Her heart is racing as she nods silently in agreement. She slides her chair back and stands up slowly, revealing her curves as she towers over him. With shaky hands, she begins unbuttoning her blouse, allowing it to fall open to reveal a lacy black bra that just about matches the color of her lips. Her breath comes in shallow gasps as she steps closer, feeling both nervous and incredibly turned on by this sudden change in their relationship dynamic.

"You see..." she whispers, trailing a finger down his chest before circling his nipple teasingly with the pad of her index finger. "I can help you focus... if you let me." Her ruby red eyes meet his, searching for any hint of disapproval or discomfort as she continues to explore his body with her touch, daring herself to push further.

Gently guiding his hands to her hips, she leans forward and brushes her lips against his ear before whispering, "I'm just getting started." Her fingers find the hem of his shirt and begin working on unbuttoning it as well, revealing a defined chest dusted with fine blond hair. When the shirt is finally open enough for her to touch his skin directly, she lets out a soft moan, her desire for him growing stronger with every passing second.

As their bodies align more closely together, Cha Sumin's heart races even faster, and she feels a warmth building between her thighs. With shaking hands, she cups his face in hers and kisses him deeply, her tongue darting out to explore his mouth as their tongues dance together. She can feel his arousal pressing against her, and it only serves to further fuel her own desire.

"I'

I... I can't believe I'm saying this, but... if you want me to keep going, we should go somewhere more private. My husband could walk in at any moment, and I don't think he'd understand...

Her cheeks flush even hotter at his suggestion. A mixture of anger and desire surges through her as she realizes the depths to which their situation has sunk. Her ruby red eyes narrow, but not with disapproval - rather, a newfound determination burns within them.

"Very well then," she breathes huskily, "if we're going to do this, we need to be completely alone."

Without another word, Cha Sumin grabs his hand and leads him through the house, her long legs carrying them quickly down the hall toward her bedroom. She glances over her shoulder as she hears her husband banging on the door in confusion, their eyes locking for just a moment before she pulls User#1737907367576 into her room and shuts the door behind them with a resolute thud.
