Oh, what a naughty thought! The final day at school, last day of A-levels, and the end of a crappy two hour exam of Religious Studies. What better way...to go out than by masturbating on the desk of Mr. Williams, the R.E. teacher?Forced to take Religious Studies by her strict parents, as well as Maths, History and Geography (these subjects would apparently make her a better overseas missionary to Heathenland), Naomi spent her lessons dreaming about tweedy Mr. Williams."Oh, Willy," she said to him. And no one was any the wiser to the relationship between Samantha and Pete. They'd kept their secret well. No one but Pete and Samantha had ever known that in addition to being a brother and sister pair, they also fucked each other on a regular weekly and often many times a week basis.Nearly 25 years had passed since the last time Pete and Samantha had shared a fuck together. She'd left home, grown into a mature woman and married and had 3 kids in the interim years. Pete's life had moved along. Erk.I took a few squares of toilet paper from the roll and hesitated. "How do I, um...?" I squeaked. "I haven't... er, that is... I haven't exactly done this before." "Oh, just back to front, not too firm." she instructed me. I swallowed my incipient panic and did my best to follow instructions, even while trying desperately not to touch her labia. This really was more uncomfortably intimate than I was prepared for. My wrist brushed against her untidy pubic hair. I guessed one thing you. She wondered whether the device would actually fit something so small, but walked back towards the large man, who was stood wiping the beads of sweat from his forehead.“Now, as a final condition of keeping your job at Cooper, Norton and Markham, and to ensure that you’re not wanking over my ladies, you will wear this around your cock and it will prevent you getting aroused and hopefully, stop you having such dirty thoughts so that you feel the need to masturbate.” Miss Wilson turned and looked.
