To punish her.

She nods, her mouth suddenly dry.

The other students begin to file out of the lecture hall, their chatter filling the air. Bianca watches as Robert gets up from his seat, looking at her with a mixture of curiosity and concern. He leans down and whispers, "Want me to wait?" in a soft voice.

Bianca hesitates for a moment, feeling a pang of guilt at the thought of hurting Robert. But the promise of what's to come with Dr. Davis is too tempting to resist. "No, it's okay," she whispers back, giving him a small, apologetic smile. "I'll see you later."

Robert nods, his smile not quite reaching his eyes. "Alright, babe. Have a good one." He gives her one last look before walking away, the click of his footsteps echoing in the emptying lecture hall.

As the last students file out, Dr. Davis closes the door behind them, ensuring they are alone. He turns to face Bianca, his eyes darkening with desire as they lock onto hers.

Bianca's heart races, her skin flushing at his intense gaze. She can't help but notice how his shirt is slightly unbuttoned, revealing a tantalizing glimpse of his toned chest. The memory of their intimate encounter the night before floods her mind, making her body hum with anticipation.

Dr. Davis takes a step closer to Bianca, his presence dominating the room. "Dressed like a slut today, aren't you?" he purrs, his voice low and seductive. His eyes rake over her body, lingering on the slit up her thigh that reveals a tantalizing glimpse of her lacy lingerie.

Bianca swallows hard, her mouth suddenly dry. "I, um... I just thought you'd appreciate the effort," she manages to say, her voice barely above a whisper. She can feel the heat radiating off his body as he approaches, his cologne filling her senses.

Dr. Davis chuckles, the sound sending shivers down Bianca's spine. "Oh, I do appreciate the effort," he says, his hand reaching out to trace the curve of her jaw.

His touch is electric, sending sparks of pleasure through her body. "But I have to punish you because you're going to get me in trouble."

A smirk plays on his lips as he leans in closer, his breath hot against her skin. Bianca's heart races, anticipation building in her core.

Dr. Davis smirks, his eyes glinting with mischief. "I was going to fuck you again, but I think your punishment is no more orgasms until Friday," he purrs, his fingers tracing teasing patterns on her inner thigh. "Then after Friday after you finish classes you are going to come to my office."

Bianca gasps, her eyes widening at his words. The thought of going without release for days makes her core clench with need, aching to be filled by his touch. "Yes, sir," she whispers, her voice barely audible.

Dr. Davis chuckles darkly, his hand moving to cup her mound through the thin fabric of her panties. He can feel how wet she already is, his cum from earlier still leaking out of her. "Such a naughty girl," he murmurs, his fingers pressing against her slit. "Already so wet for me."

Bianca whimpers, her hips canting forward as she seeks more of his touch. "I'm sorry," she breathes, her eyes fluttering closed as she surrenders to the pleasure. "I'll be good, I promise."

His touch is electric, sending sparks of pleasure through her body. Bianca's legs tremble, her skin flushed with heat as he teases her sensitive folds. "That means, no boyfriend, no masturbating, nothing," he says, his voice low and commanding. His fingers slip under her panties, rubbing her clit in slow, tortuous circles. Bianca gasps, her back arching as she grinds against his hand, seeking more friction.

"Yes, sir," Bianca whispers, her voice a breathy moan. The promise of denying herself pleasure for days makes her core clench with need, aching to be filled by his touch. She can feel the heat building inside her, her body responding eagerly to his advances despite the punishment.

Dr. Davis smirks, his eyes glinting with mischief. "You're such a **** little slut, aren't you?" he purrs, his fingers dipping lower to tease her entrance. Bianca's eyes widen, a silent plea for more passing through her gaze. "So hungry for my cock."

Her teeth sink into her bottom lip as she nods, "I...don't know how I can go two days without you in me."

Bianca's admission seems to amuse Dr. Davis even more, his chuckle low and rumbling in his chest. His fingers withdraw from beneath her panties, leaving her bereft and aching with need. He trails his fingertips up her stomach, mapping the curves of her waist, and pauses to gently brush the underside of her breast. The caress sends sparks of pleasure coursing through her frame, her nipples pebbling against the thin fabric of her dress.

"No touching yourself," he reminds her, his voice firm yet tinged with playful authority. "Your releases belong to me now. Every single one of them." With those final words, he steps back, severing all physical contact between them.

Bianca shivers, a whimper threatening to spill from her lips as reality crashes down upon her. It takes considerable effort to tear her gaze away from the magnetic pull of his eyes, but somehow she manages, directing her sight downward to the floor. While nodding faintly in understanding, she inches backward, retreating from the overwhelming presence of her professor. Her shoulders slump ever so slightly, weighed down by the daunting task ahead – enduring two long days and nights devoid of his intoxicating presence inside her.

With a quiet resolve, Bianca turns to gather her belongings, her movements mechanical as she bends to collect her bag and notebook. The rustle of papers and creak of leather echo softly through the empty classroom, punctuating the heavy silence that hangs between them. As she rises, smoothing her dress with a distracted hand, Bianca readies herself to depart, steeling her nerves for the trial ahead.

Just as she pivots toward the door, poised to escape the charged atmosphere of the classroom, Dr. Davis' smooth baritone rings out across the space, halting her progress mid-step. "Where are you going?"

Bianca freezes, arrested in motion as though bound by unseen chains. A shiver runs down her spine at the resonant timbre of his voice, a thrill darting through her system as she registers the note of expectation implicit in his question. Tendrils of tension spread throughout her being, warming her blood anew and rendering movement impossible. For a beat, she stands suspended, utterly captive to the subtle currents eddying between them.

"I... I was just heading to the pharmacy," she manages to reply, her voice wavering slightly.

Dr. Davis' expression twists, his furrows his brows in a scowl that sends a shiver down Bianca's spine. "Did I tell you that you could go to the pharmacy?" he inquires, his tone low and commanding. Bianca swallows hard, a flutter invading her chest as she registers the displeasure etched on his features. She shakes her head, her ponytail swaying gently, and her reply barely above a whisper, "N-no, sir."

The air in the classroom seems to grow heavier, thickening with unease as Dr. Davis' intense gaze lingers on Bianca, scrutinizing her every move. His eyes, like two piercing orbs, bore into her skin, and she feels the weight of his disapproval bearing down upon her. The silence stretching between them is oppressive, and Bianca's skin prickles with anxiety, her fingers closing around the strap of her bag like a lifeline. She remains stock-still, her heart pounding, as Dr. Davis' expression seems to darken, his jaw clenched in disapproval.

Suddenly, Dr. Davis moves with fluid purpose, striding towards Bianca. His footsteps echo through the classroom, each step drawing him closer, more imposing. Bianca's eyes follow him, her breath catching in her throat as he closes the distance. He stops before her, his proximity sending a jolt of electricity through her body, and his voice is low and husky, "I didn't think so."
