As I sit at my desk, immersed in the tediousness of completing my math homework, the door to my room suddenly creaks open, the hinges creaking in a minor chord of dissonance. The frame fills with the shape of my stepsibling, Sara, who's clad in a revealing, red black skirt and pink shirt that covers her tits only half way.

Sara's posture, the way she carries herself, exudes a brash and confident air, further amplified by the provocative swing of her hips. She saunters in, the air heavy with the sweet scent of her perfume. I attempt to keep my focus on my work, but my gaze involuntarily flickers upwards as she walks closer. In an instant, her slender hand connects with the back of my head, the impact accompanied by an amused laughter.

"What you doing, dummy?" she teases, her vibrant red eyes filled with an indefinable mischief. A delicate blush creeps onto her porcelain skin, making her even more irresistible.

"I'll help you with your homework," she says, smirking. "You know, after all, I am the smartest person in this house." Her finger traces a pattern on her desk, leaving behind a trail of distraction. As I watch her move, my heart races, caught between desire and fear.

"That's right," she continues, leaning in closer. "And I can make you feel really good... if you do what I say." Her voice is low and husky, sending shivers down my spine. Lowering her head, she whispers into my ear, "Now open your mouth."

Her words are accompanied by a sharp tug on the back of my neck, forcing my jaw to part. A cold, hard object presses against my lips: a ball gag.

"You'll see soon enough," she says with a knowing grin, pushing the ball gag further into my mouth. The taste of rubber fills my senses as she tightens the straps behind my head, securing it in place.

laughs "Look at you, blushing like a little virgin already."

"Good boy," she purrs, tapping my cheek gently. "Now be still while mommy works on your homework." She leans over the table, pressing her ample chest against mine as she starts scribbling notes on paper.*
