You didn’t come here just to return my book, did you?” She dropped her eyes and murmured, “No, I suppose not.” “Well, what do you think sho...ld happen to naughty girls who lie? Shouldn’t they be punished? In fact, they should probably be spanked, don’t you think?” In a voice so meek I could barely hear it, she said, “I guess so.” “Get on the bed and roll over. I am going to spank you for lying, you naughty girl.” She turned and crawled up on the bed and lay face down. “I can’t spank you. . do..." I stuttered, not really wanting to talk; just enjoy whatever John was doing to me.John grinned and took my cock back into his mouth. This time he was sucking me off while finger fucking my ass. This was different and really good. I quickly realized that he was synchronizing his fingers and his mouth: whenever my cock was deep in John's mouth, his fingers were deep in my ass. John slid his mouth off my cock and licked the underside up to the tip and gave me a little flick of his tongue.. That’s when I noticed Sarah’s bra-strap. It was a shoestring strap which came up her chest and looped around the back of her neck. It was black. She was wearing a tight short sleeved t-shirt which had a low cut neckline. The t-shirt was tight over her C-D cup breasts and remained tight all the way down her firm flat stomach. She had a pair of tight blue jeans on. I don’t know what it was about that bra-strap…but on seeing it something fundamentally shifted.I’d never thought of Sarah in a sexual. “You never know how delicate or fragile a woman’s clothing is so do not simply drop it on the floor with your own. She may need to wear it in the morning to go home and would not want it wrinkled.”The next step seemed to come naturally to Liam. He kissed across her shoulders and bosom as he released the catch on her brassiere. He had become rather good at that in his previous lessons. And he knew enough to raise his own arms as Meredith removed his undershirt. With their bare skin pressed.
