Ruby turns around to face you, her expression playful and teasing. "Come on, it'll be fun," she says with a wink. "I promise not to tell anyone." She pauses for a moment before adding, "And if you're really good... maybe I'll even help you feel better about school." Her voice is low and sultry as her gaze lingers on your crotch.

"I want you to take off my top," Ruby says softly, her voice barely above a whisper. "And then... we'll see." She takes a step closer to you, her chest heaving slightly as she exhales slowly. The air between you seems charged with anticipation and desire.

Her fingers dance over the buttons of her blouse, opening them one by one. With each button undone, more skin is revealed; her breasts pushed upwards by the lacy red bra she wears beneath.

Her heart raced as he pulled a small white pill from his pocket and held it out to her. "Take this," he commanded, his voice steady despite the look of lust in his eyes. "It'll make you unable to orgasm even with the vibrator inside you." Her brow furrowed in confusion, but she didn't dare disobey him.

She swallowed the pill dry before taking a shaky breath. "What if I can't..." she started, her voice trailing off as she realized what he was implying.

"Nothing," she stammered, feeling heat rise in her cheeks. "I just...thought maybe you'd want me to..." Her words trailed off as he gave her a look that silenced her completely. The thought of disappointing him was enough to make her stomach twist into knots.

"Good girl," he murmured, his hand moving up to cup her cheek again. "Now get to class."

She gasped, her fingernails digging into your shoulders as she fought to maintain control. Her hips bucked and twisted against the bed in time with the vibrator's movements, seeking release from the building tension. "Master," she whispered his name like a prayer.

You leaned in closer, kissing her neck and earlobe as you watched her lose herself to pleasure. Her skin flushed red beneath your touch, and beads of sweat formed on her brow.

With a sharp intake of breath, she froze, her body still quivering from the sensations that had been coursing through her just moments ago. You smiled down at her, satisfied with the display of submission and obedience. "That's my good girl," you murmured, pressing another kiss to her cheek. "Now get some rest. Tomorrow's going to be a long day."

She nodded meekly, her eyes already growing heavy as she surrendered herself to sleep.
