She was the first to arrive, as normal, and sat down at her seat, waiting for her friends to arrive. Maths was her favourite lesson, because she was OK at it, and she had an amazingly good looking young teacher.
Gemma had always wanted him, and she made sure he knew that. Every lesson she'd torture him, until at one point he'd stop in the middle of the class trying to control himself.
He was a married man, and almost twice Gemma's age, but she didn't care. She knew what she wanted.
Maths was as normal. Gemma waited to get Mr.Williams attention, and carefully and slowly applied her lip stick. This did get her noticed. Then, half way through the class, she took out her pencil and stroked her hot and wet pussy, making sure he had full view. She slipped the pencil in and out, until she shook out her orgasm. She took her pencil out of her dripping cunt and sucked on it. Mr.Williams couldn't help but stare. Suddenly the bell rang for the end of school, making Mr.Williams jump. The students were half way out the door before Mr.Williams could say anything, but he managed to call Gemma back.
Gemma walked slowly to Mr.Williams' desk, trying to hide the grin on her face. As she approached she noticed the erection in his pants. The fact that Gemma could turn her Maths teacher on, turned her on. "Your behavior in my class this afternoon has been appalling young lady," Mr.Williams said. Gemma still couldn't wipe the smile off her face. "You liked it though sir." "What? No Gemma, you're my student, you're only 17 for Christ's sake." "Well, your pants don't say that do they sir?" Quickly without letting Andrew reply, she grabbed her teacher's erect hard dick through his trousers.
"Oh God Gemma, what are you doing?!" "Ssh, or someone will hear us, keep quiet." Andrew, even though still wasn't a hundred percent sure, nodded his head and did what he was told. Gemma descided to get straight to it, she ripped off her 30 year old teacher's trousers and boxers, and out sprang a very big hard erect penis.
