He walked over and sat down on her bed, gesturing for her to walk towards him. When she was a few steps away, he held up a hand to stop her.
"OK," he said, his voice already deepening in his excitement, "that's far enough. Now I want you to take your blouse and skirt off for me while I watch."
He was pleased to note that she immediately lifted her hands to start undoing the buttons of her shirt. He wasn't so pleased though when she started swaying awkwardly, in a very bad impression of a stripper.
"No," he snapped, "don't undress like you're being paid to turn me on. Undress like you normally would, just a little slower."
Looking slightly relieved that he wasn't expecting her to dance she did as he asked, unbuttoning her shirt and slowly pulling it open, exposing her perky tits and dusky pink nipples. As he had already noted, they were pebbled and erect with excitement. She slowly slid the shirt behind her, allowing it to slip off her arms and fall to the floor.
"Now the skirt," he said. He saw her shiver slightly at his words. The room was warm, so he realised she was getting excited.
She unzipped her skirt and pushed it down past her hips, then gave a little wriggle to encourage it to slide down and pool around her feet. He didn't know why, but that wriggle really turned him on. Maybe it was the unconscious way in which she did it, like it was something she did every day.
She stood in front of him wearing just her knee high white socks, and a tiny scrap of white panties, so lacy and flimsy she might as well have gone without. But the contrast of those sexy panties against the childish knee high socks was startlingly erotic. His cock throbbed hard within the tight confines of his pants, and he took a moment to adjust himself, noting with satisfaction how quickly her eyes were drawn to his movement, and how her pupils widened just slightly.
"Okay," he said, "that was really good and very sexy. Your beautiful little body makes me so hard and achy. Come here baby girl."
She stepped towards him, pausing briefly to shake her feet free of her skirt, and paused a step away. As he was sat on the bed her head was slightly higher than his. Not by much though, compared to his six foot she was really tiny. He mouth was lined up perfectly with those lickable nipples of hers.
"I want you to put your hands behind your back," he said, "and clasp your hands together. I know you might want to touch, but if I'm going to teach you properly I can't have any distractions. No talking either. Understood?"
"Yes sir," she said, immediately clasping her hands behind her, which had the added bonus of thrusting her tits forward towards his face. He genuinely couldn't believe his luck with this girl. She had been so naughty and disobedient in class, he was convinced he had a brat on his hands. But she was turning out to be so perfectly submissive. He had a feeling he could do anything he wanted to her, violate her in every way imaginable, and she would still come back for more.
Deciding to ease her in slowly, he leaned forward and started to give her nipples the attention they so clearly craved. Holding her still with one hand on her hip, he used his other hand to tweak and tug at one erect bud, sucking the other one into his mouth and torturing it with his tongue. She started to moan almost immediately, and he could tell she was squeezing her thighs together a little tighter.
Excited at the thought of her arousal, he grew a little rougher, and nipped at her swollen nipple with his teeth. It wasn't much of a bite, he barely grazed her, but she leapt backwards in shock, and blurted out "ow, you bit me!"
Quick as a flash he was up off the bed and towering above her. He clapped one hand over her mouth, and grabbed her throat with the other.
"Did I not just fucking tell you no talking?" He roared, leaning close to her face for emphasis. Her eyes grew impossibly wide, and tears immediately sprang out of them. He could feel her lower lip quivering under the palm that was stopping her from speaking.
He stepped back towards the bed, pulling her with him. Getting so close to her face he could see his reflection in her wide eyes, he said "you need to remember your position young lady. You are the pupil. I am the teacher. I give commands, you obey them. I tell you not to talk, you stay silent. I tell you to suck my dick, you choke on it. I tell you to jump, you ask me HOW FUCKING HIGH."
These last words were so loud and so forceful that she flinched away from him. Tears were pouring down her face now, and he realised he could feel her trembling under his hands. He slowly removed his hand from her throat, but kept the other hand over her mouth.
"Now," he said, his voice deep with the arousal that scaring her had caused. "I'm going to take my hand away from your mouth. You will not say anything, or make any sound at all. Understood?"
