Kat lay on the bed idly playing with herself, her hands roaming freely but gently, barely touching her soft, pale skin. She toyed with the cups of her lacy black bra, smiling as her already aching nipples responded, becoming even harder. She knew he loved her nipples and how sensitive they were.
Her fingers roamed further. No panties to check. She smiled; it was rare that there were, these days. She knew better than to touch her pussy yet. He would know somehow, he always did, and then there would be trouble. She checked the seam on her stockings. Mmm nice and straight. Hopefully he would enjoy seeing them when he bent her over to spank her. She smiled again, knowing it was almost certain that he would spank her.
It had already been a fun evening. Kat had been looking forward to seeing Sir tonight, although they had not spoken and barely touched so far that night. He had invited her to a concert, to hear him play, casually mentioning that there was a room booked in their usual hotel for afterwards. She had jumped at the chance, they were never together enough, and it had been nice to see what he did with himself when she wasn't there.
The evening had begun well. As usual, Sir had chosen the outfit. Black hold-ups, nice heels and a lacy bra that complimented her beautiful young breasts. Her going out collar, too. The lacy one he had bought her the night he had collared her. She felt a tingle as she thought of that night, and of what it had meant to both of them. Her fingers traced the elegant, high collar, making her moan a little in pleasure as she remembered.
The outfit, as such it was, had been finished off with a mid-length black coat and a silk scarf. She had felt such a slut going out like that, especially to a smart event, and had worried that she would be discovered somehow. Even driving there had been incredibly erotic, but then Sir seemed to have a way of turning so many of her daily routines into something sexual that would leave her gasping.
At the concert, he had seen her immediately she walked in. Kat could tell from his smile that he was pleased with her, and pleased to see her there. He had given her the choice of just meeting him at the hotel after, telling her that he didn't want to force her to sit through an evening of him talking and playing. Silly Sir, she thought. Of course she would want to, and she hadn't been disappointed. She didn't usually listen to classical groups, but they played so beautifully and it had been interesting to see and hear Sir in a whole new way. She just hoped that she wasn't going to be given a test, because... well, because she had been focussing on very different things during the evening, and her imagination had fuelled her already aroused state.
