Pausing momentarily before continuing with his lesson, his eyes drifted over to where Denise Corby was sitting. He was shocked at how much of her naked thighs were exposed under her hiked-up skirt.

"One of the most important things in speech is the way you sound your vowels, and now I want each of you to individually say them to me."

Glancing to the back of the room he noticed the sultry smile on Denise's face as she re-crossed her legs.

"Denise," be said, walking toward her desk. "Please stand up and go through your vowels for me."

The girl slowly rose to her feet and her deliciously big tits straining out against the front of her tight sweater. There was a warm teasing glow in her eyes as she smiled at the teacher standing directly in front of her.

"Now remember," he said. "I want these sounds to come from your diaphragm, not your throat."

"From here?" she whispered, thrusting her big tits up and out at him.

"Yes, Denise," he stammered. "From there."

She began uttering the sounds of the vowels in a surprisingly soft, resonant voice, clear as a bell.

"That's fine, Denise," he smiled. "This time, form the letter 'O' with your lips before you make the sounds."

Watching the sultry teen form her lips in a moist circle, the teacher suddenly thought how wonderful they would feel around his cock. Still looking the teacher straight in the eye, she teasingly darted the tip of her tongue out and slowly circled her lips with it, her eyes half-closed in an expression of ecstasy.

Seeing the excitement on the teacher's face, she brazenly repeated the sensual gesture two or three times before she finally sounded the vowel, pleased that she was able to turn him on so easily.

"That's fine, Denise," he smiled, resting his hands on her shoulders. "Now repeat it again."
