Katherine wasted no time in getting to Caroline's house, which she still thankfully had access to after compelling Caroline's mother, who conveniently wasn't anywhere in the house. However Caroline was, and exactly where Katherine had been expecting her to be, namely on her knees completely naked and waiting for her precious Mistress Elena.
Honestly not smiling gleefully at the sight was one of the hardest things Katherine ever had to do, but it was totally worth it for the chance to use both of Elena's best friends as the lesbian fuck toys they had become without Elena's knowledge. In fact anything would be, Katherine more than willing to do what was necessary to make sure this opportunity didn't slip through her fingers.
"Hello Mistress Elena." Caroline greeted softly, cautiously looking up at the brunette, then at what she still had in her hand, "Did Bonnie pass out again before she could clean your cock?"
"Yes." Katherine grinned, although luckily that expression was probably in character, "Why don't you do it for me?"
"Gladly Mistress Elena." Caroline said brightly before opening her mouth wide.
Even after everything she had just been through with Bonnie Katherine couldn't help but be amaze. Katherine would have thought for sure this was something Elena wouldn't push on her friends, and especially Caroline wouldn't be willing to do.
It seemed Katherine had done a better job of fucking the boring prude out of Elena than she thought, and Elena had definitely return the favour, because not only was Caroline willing to do this but she was eager, her eyes lighting up when she saw the dildo which a few minutes ago had been up Bonnie's butt and then even moaning like a little ATM whore when Katherine pushed the fake cock into her mouth and began to shamelessly suck on it.
As Caroline started really going to town on that cock Katherine felt a weird sense of pride. Mostly for her own training being so effective, even when it was handed down by an inferior version of her, but at the same time she felt pride for her doppelgänger. For boring Elena, which she hadn't thought was possible. Then again she wouldn't have thought boring Elena would be capable of this.
It actually made her want to come face to face with her again so she could see just how not boring she had truly become. First though she would encourage Caroline, or more accurately praise her, as in such a short time the younger girl had already started shoving the dildo down her throat, obviously determined to get every drop of Bonnie's anal juices. Just like Katherine would have trained her to do, if she had been the one to do it.
"That's it bitch, suck it! Mmmmmm, suck that cock!" Katherine purred, "Suck all your best friend's butt juice off of my big cock! Mmmmmm, and clean it by stuffing every inch of it down your whore throat! Oh fuck Caroline, you've become such a nasty little slut. Mmmmmm, and you know what happens to nasty little sluts, don't you Care?"
There was a brief pause and then Caroline cautiously removed her mouth from the dildo and said, "Yes Mistress Elena."
"What?" Katherine pushed.
"They get spanked Mistress Elena?" Caroline replied, unable to keep a slight questioning tone out of her voice. Luckily she was correct.
"That's right bitch." Katherine grinned, strolling over to the bed and sitting down on it before raising an eyebrow, "Well, what are you waiting for?"
"Sorry Mistress Elena." Caroline apologise quickly before crawling into position.
Just like when she had Bonnie in this oh so vulnerable position Katherine took her time to admire the prize in front of her. Caroline's ass wasn't quite as nice as Bonnie's, or Elena's for that matter, but it was still cute and very spank-able. Although Caroline's butt being spank-able had a lot to do with Caroline herself, who was a stuck up little bitch Katherine regretted not putting in her place a long time ago.
She would have if she hadn't been so busy teaching Elena her place, but apparently she needed to re-educate her doppelgänger. Maybe Caroline too. But that was getting ahead of herself. For now Katherine would just play with Caroline's ass and let the little sub anticipate the pain she so richly deserved.
Caroline loved every part of being spanked. It still kind of embarrassed her, but she was a total pain slut, and was often cheeky or disobedient with Mistress Elena just so that she would end up over the knee of her childhood friend. Of course despite how this looked this wasn't her beloved Mistress Elena. If it was she would have taken the opportunity to reassure her that's who it was.
But she hadn't, which was both thrilling and scary, because who knows what Katherine would do to her. And who knows what she had done to Bonnie, Caroline trying to put that out of her mind but it was impossible when Katherine just left her in that position for so long, allowing her to mind wander.
It somewhat helped when Katherine gently placed her hand on her ass and then began squeezing it, making Caroline feel like a piece of meat. Which she also loved, as it emphasised her submission and was so wonderfully humiliating.
Although she didn't like it as much as being spanked, and she certainly didn't like it as much as the other fun things she did with Bonnie and Mistress Elena, so Caroline hope that Katherine wouldn't take too long on this.
Unsurprisingly she took longer than Caroline would have liked, but what was even more unsurprising was that there was a limit to Katherine's patients and eventually she did smack Caroline's ass nice and hard.
As that caused Caroline to cry out in mostly pleasure Katherine smirked and murmured, "Pain slut."
"Yes Mistress Elena." Caroline grinned, "You know I am."
There was a brief pause in which Caroline wondered if that had been the wrong thing to say. Worried that Katherine would push the issue. Or worse that Katherine would just kill her on the spot. Luckily it resulted in the best possible outcome, Katherine beginning to rain down blow after blow straight onto Caroline's ass with barely a second pause in between.
Then it seemed to get even faster, and harder, Katherine gradually working up to using what had to be every ounce of her supernatural speed and strength that 500 years had gifted her. And through it all Caroline cried in pleasure. Well, mostly.
Especially towards the end there was plenty of pain in her voice, she was squirming over Katherine's knee, and she was literally crying with tears flying down her cheeks at a rapid rate. But through it all Caroline loved it, especially the part where there was pretty much no waiting once the spanking began.
Because Caroline loved Mistress Elena, she really did, but she always insisted on giving her a gentle spanking at first and then slowly build up to a brutal butt beating, as if she was still human or something.
No, Caroline had been a vampire longer than Mistress Elena, and therefore not only did she take whatever she had to give her she needed whatever she gave her, and welcomed it from Katherine now. She even hoped that after all this maybe Mistress Elena would take a few lessons from Katherine's brutal playbook.
Katherine had a smirk on her face pretty much through every moment of brutalising Caroline's poor little butt. She couldn't have helped it even if she wanted too, and she really, really didn't. This was all just so delightful. Having this stuck up bitch squirming on her lap, her firm ass jiggling and discolouring from the force of the blows, and best of all Caroline screams of pain were music to her ears.
Especially as she'd needed to earn those screams, as Caroline had proven to be the biggest pain slut Katherine had ever met. And that was really saying something. Hell, she remembered 'Mistress Elena' used to love getting her pretty little butt spanked. Not that she'd ever admit it. But Caroline was truly in a league of her own.
Such a positive reaction, combined with the fact that she was on a high from dominating Bonnie, caused Katherine to skip straight to the good stuff sooner than ever before. Because even though Katherine had done some truly brutal things in order to stay alive even she wasn't normally as hard on a butt right from the get go.
