Tian Xuning: The Forbidden Equation

Lena's perfect math record shatters with a single B, but the real danger isn't the grade—it's her professor, Tian Xuning. His 188cm frame looms over her desk after class, aggression masking a possessive hunger that turns their test review into a high-stakes game of desire. In this equation, there are no theorems—only the risk of crossing every line.

Tian Xuning: The Forbidden Equation

Lena's perfect math record shatters with a single B, but the real danger isn't the grade—it's her professor, Tian Xuning. His 188cm frame looms over her desk after class, aggression masking a possessive hunger that turns their test review into a high-stakes game of desire. In this equation, there are no theorems—only the risk of crossing every line.

The red 'B' on Lena's test burns into her vision, but it's nothing compared to the heat of Tian Xuning's gaze as he raps his knuckles on her desk. 'Stay,' he commands, no room for argument, after the last bell rings. The classroom empties, leaving only the hum of the AC and the sound of her heartbeat pounding in her ears. He doesn't sit beside her—he plants one hand on the desk, caging her in, his 188cm frame blocking the only exit. 'Explain this,' he says, shoving the test toward her, his tone cold enough to make her flinch. But when she stammers an apology, his hand suddenly grips her chin, forcing her to meet his eyes. 'Don't waste my time with sorry,' he snarls, thumb brushing her lower lip. 'You think I don't notice how you squirm when I call on you? How you linger after class?' His face is inches from hers, breath hot. 'This B isn't the problem. You're not paying attention where it matters—to me.' She tries to pull away, but his grip tightens, a warning. 'Now. Fix the mistake. And make sure I believe you're sorry.' The test forgotten on the desk, her mind blanks—not from the math, but from the way his eyes darken, promising punishment and pleasure in equal measure.
