| Rob looked up at the eighteen-year-old blonde stood in front of him,
"This is just not good enough Rebecca."
She gave him the well practised "I don't care" look of teenage girls the world over and began to inspect her nails.
"I know all you're interested in now is having a having fun, boys and looking good..." and boy did she look good... Kind of short, about 5'2" he reckoned, blonde hair just a little past her shoulders, and in that school uniform! Wow! The short navy skirt showing off her shapely, lightly tanned legs, a white blouse, unbuttoned as far as she could get away with, with just a hint of her bra showing through the material, and her school tie hung loosely around her neck hanging down over those perfect, firm, young breasts. Rob forced himself to remember what he had been saying
"... But this is a very important year for you. You need to do well. I know you're capable of it, you just need to put in the effort. Now, I've spoken to your mother and we've agreed you will be staying after school every Thursday for extra tuition with me." Her face was thunderous...
"But, sir!" "No buts... It's final" With that, Rebecca turned round and stormed out of the room. Rob watched the way her skirt swung over her firm, round arse as she walked away.
Two days later it was Thursday, Rob was waiting in his room for Rebecca to turn up. She was already 10 minutes late. He heard footsteps along the corridor, the door was flung open and in she came, slammed her bag down on the table and sat down, slumped in her chair. Rob wondered if she realised her skirt had ridden up when she slouched, and he could see the tops of her soft, smooth thighs. He struggled to tear his eyes away, and when he looked up, she was staring at him. Did she know he'd been trying to look up her skirt? He coughed...
"Right Rebecca. We better get started then..."
He explained the work to her and set her off doing a task whilst he carried on with some marking at his desk. The room was silent apart from their breathing and the sound of pens on paper, then he heard her shift in her seat. Glancing up he couldn't believe what he saw. Rebecca's skirt had ridden up further, and her legs were slightly apart giving Rob a perfect view of her black, lacy thong. He felt his cock stiffen. He looked up at her face and she was looking back, grinning.
"It's a bit hot in here isn't it sir?" She said, taking off her tie and unbuttoning her blouse still further, just letting Rob see that her bra was a matching black lace. "I don't think I understand this question sir. Can you help me?". Taking a deep breath, he walked over and stood behind her to explain, leaning over her and looking down her top. Those breasts were just so perfect, he could imagine holding them, stroking them, sucking on them.
"Are you OK sir?" Rebecca asked, looking up at him and grinning. "Only, you look a bit..." She glanced at his crotch and licked her lips "flustered."
That was it, Rob couldn't take anymore. "You dirty little bitch..." He grabbed her out of her seat and pushed her on the table, his hands groping at her, his mouth on hers, ripping open her school blouse.
"Sir, stop it! Stop it!" She pushed him off her looking shocked. "What are you doing?"
"You come in here and show me your knickers and bra, flirting with me and now you ask what I'm doing? I'm going to give you a damn good fucking that's what I'm doing!"
"Please sir, I was only messing around, trying to wind you up. Please don't hurt me, I've... I've never had sex before."
"I find that hard to believe, a little slut like you." He grabbed hold of her neck, "I bet you show your panties to all the boys, you little cock tease. No, you can't come in here and act like that, and not expect anything to happen. I want to fuck you. I want to suck on your perfect little tits and make you wet. And then I want to stick my big cock up your tight little whole and make you cum. I bet you'd like that wouldn't you..?"
"No sir...." She said but she didn't sound so convincing...
"You wouldn't like me to lick, and bite your nipples and play with your little clit, then stretch you wide open with my huge cock? I don't believe you..." He traced his finger up her leg, under her skirt and inside her thong. "Just as I thought, your tight virgin pussy is all wet." He kissed her again, and she kissed him back, their mouths wide open, pressing together. He unbuttoned her blouse and took it off, playing with her tits through her bra before that. Then she froze.
"What now?" He exclaimed, taking a step back and drinking in the sight of this schoolgirl, sat topless, with her skirt up round her waist in front of him.
"You shouldn't be doing this to me, you're my teacher!"
"Don't try telling me you don't want it you little slut. I can feel how wet you are" and he slipped his finger back inside her thong, searching out her engorged clit and gently rubbing it.
"Oh god" she moaning, thrusting against his hand.
"Do you still want me to stop?" He asked.
"No! Please, no..." She begged him. "Fuck me, please, fuck me!"
Rob didn't need telling twice and he removed the girl's thong in a second, and unzipped his fly, and pulled out his thick, hard cock. He began wanking himself off with one hand and watched her. Her eyes were wide.
"That will NEVER fit inside me!" She exclaimed.
"It will, and you'll fucking love it." With that he positioned himself at her entrance and in one, hard thrust he was inside her.
"I thought you said you'd never had sex before?"
"I haven't..." She said, breathlessly... "But I have been playing with myself. Fucking myself with my fingers, imagining what it would feel like to have a prick inside me."
"And what do you think?" Rob asked, slowly thrusting in and out of her tight, wet hole.
"It feels so good, I feel so full, so stretched, but I want more, still more..."
He thrust harder and deeper into her and she cried out like she was in pain, but the look on her face, and the way her hips thrust back at him said otherwise. The dirty little slut was loving it!
Suddenly he pulled out of her..
"Why did you stop?"
He walked over the his desk, pulling her by the hand, and he sat down at his chair.
"Take off your skirt, I want you naked. Now, kneel down and suck my cock."
"But I don't know how to!"
"Just lick it and suck it, make sure it's wet, and be careful of your teeth. Now kneel down and suck!"
And suck she did! Looking down Rob couldn't believe his luck, here he was, sat at his desk, while a naked, blonde, student was sucking him off! He grabbed her hair, forcing her to take all of him into her mouth, her throat... He felt himself about to cum and pulled her off, yanked her up to her feet.
"Lie face down on my desk."
She climbed up and lay there... He admired her perfect, round arse, kneading her cheeks, pulling them apart to see her little puckered opening. Moving his hands in smaller and smaller circles he massaged her arse, moving closer and closer to her anus, then massaging her there with one hand, he began to frig her clit with the other. Soon she was rolling her hips, writhing around and moaning, and he pushed his thumb into her arse. She groaned loudly. He pushed further and further into her, feeling her loosen up, then, still with his thumb in her hole, he pushed his cock into her pussy and began pumping her. The little cow was loving it. Her hips were bucking up to meet him and her groans were getting louder and louder, then, with a shudder, she came.
"Liked that did you? Well, there's plenty more where that came from...."
And with that he pulled his cock from her pussy, all wet with her juices, and thrust it into her arse. She moaned and arched her back, he manoeuvred her onto all fours and reached his hands around to play with her tits and clit... Teasing her body while he fucked her from behind.
He still couldn't believe he was stood here, in his classroom, fully clothed, fucking one of his students up the arse on his desk! And the filthy little cow was loving it! Rob needed to cum, and soon. Taking out his cock he sat down on his chair again, and pulled Rebecca onto him.
"Now it's your turn to fuck me. Fuck me and play with yourself. One hand on your clit, the other on your tits. Show me what you do on your own" and he sat back while the little, blonde schoolgirl bounced up and down on his cock, with one hand on her clit, the other playing with her bouncing breasts. She looked so dirty, she was loving it so much, her eyes were closed and she was moaning loudly... Rob needed to cum NOW.. He grabbed her by her hips, forcing her down onto his cock, harder and harder, and she was moaning louder and louder, he forced one of his big hands over her mouth to keep her quiet while he pushed her down hard onto his cock... He felt her muscles tighten around him as she came and it tipped him over the edge making him spurt hot cum inside her no-longer-virgin hole.
Rob pushed the girl off of his lap, zipped up his flies and stood up.
"I think you should get dressed before someone catches you Rebecca" he said, walking over to the desk where she had been sat, picking up her soaked thong and putting it in his pocket before heading for the door. "I'll see you next week. Don't be late."
