From the other side:
He looked at her as the stood, squirming and spread-eagled against the wall. He pussy juices glistened attractively where she had been spanked, and her pert, tight ass was so red and inviting right now. Every time they met, he thanked his lucky stars that they had got together the first time. She was just what he had been looking for - a dirty, submissive mind - but still far more innocent than she believed, and able to still be shocked by his desires and demands.
He was pleased with Kat tonight. She had come to the concert, even if she had clearly spent the evening on the verge of cumming from excitement and need. She had, as always, dressed perfectly and was clearly ready for whatever he felt the need to give her. Smiling, he decided that he would step it up a gear or two this evening. After all, her face was so prettily made up, and it would look even better when her tears started to make the mascara run.
He took hold of her hair, his balls tightening with pleasure as she gasped and looked into his eyes. He adored that look, lust and worry combined. The awareness that she would do anything he wanted, yet trusting and pleading that it would not be too hard or unpleasant for her.
He smiled at her and kissed her passionately, their tongues seeking each other out, exploring their mouths. He moaned as she bit at his lip, her hands, still behind her, reaching back to caress the now aching bulge in his trousers. She was learning well, but he was not going to let her distract him into fucking her. Yet.
He pulled her away from the wall by her hair, and dragged it down so she fell to her knees, giving a little squeal as she did so. He loved that, it sounded so innocent, one of the reasons he had chosen her. They were by the door now, a long way from the bed. He picked up the flogger from by the door. "All fours, girl," he commanded.
She pouted, knowing from long experience what was coming next. Her big puppy eyes pleaded for something different. "Haven't I pleased you, sir? Please can I suck daddy instead?"
Oh god, it was tempting, and she knew it. Her oral skills were excellent, and he never tired of it. No man would, he thought. Her lipstick glistened as she licked her lips, looking into his eyes, making him want it so much. But it hardened his resolve even more than his cock. She would not top him this evening, and would be made to realise that she shouldn't try.
"Why are you not on all fours yet, girl?" he barked.
She dropped to the position, ass pushed up towards him, back arched to present her tits prettily, hair falling sexily over her shoulders. He watched as her breathing quickened, ready for what she knew would come next.
"I won't flog your disobedient ass all the way to the bed, as you were expecting, dear," he said gently. He saw her breathing ease a little as she relaxed. "No, I am going to make you crawl round the room twice, and flog your ass and pussy the whole time. You will NOT try to get your own way with me. Understand?"
He was pleased to see that she gasped. Whimpered a little, then took a deep breath. "Thank you sir. Yes sir," she answered.
"Off you go, girl. And if you go too fast, I will wait until the end, then make you do the whole thing again. And again. And again, until you have got it right." He smiled as she set off at a snail's pace, crawling around the room, her ass wiggling provocatively, her legs just far enough apart. Weighing the flogger in his hand, and keeping close behind her, he started to flick her pert ass, enjoying her little gasps and yelps as he made contact. It was a nice warm up for her, but not nearly enough, and she knew it, but he knew that waiting would torment her even more.
