He decides to mention Rachel

"I have a girlfriend," David informed Ms. Myers, though he probably should have been thinking of Rachel more when he made these changes to her with the curse. Thinking of how to outsmart Ms. Eveline Myers was a difficult task, given she was rather smart and normally rather sadistic herself.

Ms. Myers raised an eyebrow, her full, plump lips curving into a slow, knowing smile.

"You do?" she purred, leaning in so close that her breath ghosted across his mouth, her knee-length cherry-red hair spilling forward like a silken curtain around them both. The scent of her — warm, faintly floral, and unmistakably aroused — filled the small space between them.

Leaning in closer, Ms. Myers deliberately let her newly perky breasts brush against his chest. She tilted her head, studying him with sparkling, mischievous eyes that still held decades of sharp intellect.

"Mmm… how very responsible of you to mention her now," she whispered, her voice low and velvet-smooth, dripping with mock sweetness. One manicured finger traced a lazy circle on his collarbone, slow and patronizing. "Tell me, David… does your little girlfriend know what you’ve been doing in this office? Hmm?"

Titling her head, Ms Myers’ eyes sparkled with amusement as she looked down at him. "Does she know you just turned your strict old professor into… this?

She stepped back just enough to let him look.

Tracing slowly down her sides, her hands followed the sharp inward dip of her waist before flaring out over full, rounded hips. The unbuttoned blouse hung loosely open, framing the smooth, heavy swell of her breasts as they rose and fell with each breath. Knee-length cherry-red hair spilled down her back in thick, glossy waves, the silky strands brushing teasingly against the backs of her thighs with every subtle shift.

A slow, deliberate twirl of her heard sent the heavy cascade of red swinging dramatically behind Ms. Myers like liquid silk. Then she closed the distance again, pressing her warm, curvaceous body firmly against his.

"Or have you been keeping all these delicious little secrets to yourself?" Her smile turned wicked. "I’m not asking you to leave her, sweetheart. I’m not that cruel." She leaned in again, lips brushing the shell of his ear as she added in a conspiratorial whisper,

David almost laughed. Oh, if only you knew, he thought smugly. Rachel wasn’t some oblivious girlfriend he had to hide things from. She remembered every single change he’d ever made with the curse. She had literally volunteered to be his test subject. Trying to play the “secret affair” card on him was almost cute in how badly it missed the mark.

"But you did give me this body. You made me feel young and hungry again… and it would be terribly rude to leave a lady in this state without at least letting her thank you properly, wouldn’t it?" She let her hand slide down his chest, fingertips teasing the hem of his shirt.

"Think of it as… extra credit. Private tutoring. No one has to know. You keep your sweet little girlfriend, and I get to help my very favourite student work off all that terrible stress the curse has been causing you."

Ms. Myers pulled back just far enough to lock eyes with him, her expression a perfect blend of playful innocence and blatant desire.

"Besides," she added, voice dropping even lower, "I’m still your professor. It’s my job to make sure you’re… thoroughly satisfied with your education."

Before David could respond, Ms. Myers closed the distance in one smooth, decisive motion. She cupped his face with both hands and pulled him into a fierce, hungry kiss.

Her lips were soft, full, and insistent. They pressed against his with surprising heat. The moment their mouths met, something instinctive took over in David. Thanks to his earlier impulsive curse about being an expert lover, he kissed her back with perfect skill and confidence. He tilted his head just right, teasing her lower lip with his teeth before deepening the kiss. His tongue slid against hers in a slow, sensual dance that drew a soft, needy moan from deep in her throat.

Melting against him, Ms Myers' newly youthful body pressed firmly into his. One hand slid into his hair while the other gripped the front of his shirt, holding him exactly where she wanted. She kissed him with decades of pent-up hunger, deep, wet, and commanding. Long cherry-red hair cascaded around them both like a silky curtain, brushing against his arms and shoulders.

When she finally pulled back for air, her lips were slightly swollen and her breathing was ragged. Her eyes gleamed with lust and triumph.

"Mmm… very impressive," she purred, still holding his face. "That curse of yours clearly knows what it’s doing."

She leaned in again, this time brushing her lips teasingly against his as she whispered:

"Now… make the room soundproof for me, David. Say it. Make sure no one outside this classroom has any idea what your professor is about to do to you."

Fingers tightened in his hair, pulling him closer. She gave him another firm, possessive kiss. This one was shorter but no less demanding. Her lips claimed his with hungry urgency, tongue sliding boldly into his mouth as she pressed her body flush against him. Deep and intense, the kiss savoured the way his skilled response matched her own, drawing a low, satisfied hum from her throat.

Pulling back just enough to look at him, her lips slightly swollen and breathing ragged, she kept her body pressed tightly against his. Warm and insistent, it dared him to resist.
