Katherine Pierce hated disguising herself as her boring doppelgänger Elena Gilbert. She had far too frequently, and wasn't particularly looking forward to doing it again, but curiosity got the better of her.
See, not only was sweet little Elena now a vampire, but she had broken up with Stefan and was keeping both Salvatore brothers at arm's length, which begs the question, why? Had she become bored with them?
Katherine could understand that, if it was the other way around, but she was genuinely surprised by this turn of events. And it made her wonder, was it possible that vampire Elena wasn't so boring? The answer was yes, and Katherine could never have guessed why.
Now Klaus was dead and the surviving Originals had left for New Orleans Katherine was free to stalk Elena without any hassle. Unsurprisingly she seemed like the same old boring Elena, at least until she broke into her doppelgänger's home and found a very surprising, and delightful, sight waiting for her in Elena's bedroom.
Namely Bonnie Bennett kneeling on the floor with her head lowered and without a stitch of clothes on, unless you count the cute little dog collar, which Katherine didn't. Katherine stared with disbelief at this sight for a few long seconds, then Bonnie lifted her head and gave her a searching look.
"M, Mistress Elena?" Bonnie murmured cautiously.
Mistress Elena! Wow, this was better than anything Katherine could have possibly imagined, a wicked grin crossing her face as she tried to imagine how this could have possibly happened.
Then she realised she was giving away the fact that she wasn't Elena, and quickly change the expression on her face while beginning to look Bonnie up and down like a piece of meat.
No stranger to the role of 'Dom' Katherine then started slowly circling the tasty morsel in front of her, fighting the primal instinct to dig her fangs into the soft flesh on display, satisfy her craving for blood and leave Elena the dead body of her friend and apparently sex slave as a gift.
However even if she could do that, and that was really debatable given how powerful Bennett Witches were, Katherine had a much, much better idea.
Yes, she thought to herself as she came to stand directly in front of Bonnie, Katherine would have her way with this little morsel and leave Elena a gift all right, but it wouldn't be a dead body. It would be a well fucked one. The only question was, what to do first?
Well, Katherine was also wondering whether Elena had any toys laying around to amplify the fun and thinking of all the wicked things she could do to Bonnie, but mostly she tried to decide what to do first, ultimately going with the most obvious answer, because she just couldn't resist.
"Have you been a bad girl Bonnie?" Katherine asked.
"Yes Mistress Elena." Bonnie quickly replied.
"Well then..." Katherine said, slowly walking over to Elena's bed and sitting down on it before patting her knee, "I better spank you."
"Yes Mistress Elena." Bonnie replied, slowly crawling onto Katherine's lap.
Bonnie was at least 90% sure this wasn't her precious Mistress Elena, but her Mistress's evil doppelgänger Katherine Pierce.
However they had all known it was inevitable that when The Originals were gone, and maybe even before that, that Katherine would return, and they had come up with various different ways of dealing with her over the past year or so that she had been absent from Mystic Falls.
Mostly involving killing her for what she did to Jeremy, but now thanks to Bonnie the youngest Gilbert was back in the land of the living, so Mistress Elena came up with a more mutually enjoyable plan for dealing with her evil twin.
One Bonnie didn't really approve of, but Katherine was no threat to her and she wouldn't dream of disobeying a direct order from her Mistress.
So Bonnie pretended she wasn't suspicious and crawled directly onto the lap of 'Mistress Elena'. Nothing happened for maybe an entire minute, then the doppelgänger went for obviously admiring Bonnie's butt to sliding a hand over it, squeezing and groping it like a butcher inspecting a piece of meat.
Which wasn't exactly telling, as Mistress Elena did this all the time, although Bonnie could easily imagine that Katherine would do the exact same thing.
Likewise for the first smack, which came after a little groping and was wonderfully hard, the sound of flesh on flesh echoing throughout the room nearly as loudly as Bonnie's cry of delight and anguish.
More of those cries came as the woman who certainly looked like her friend got into the kind of steady and confident rhythm that Bonnie imagined that could only come from experience.
Not that she could say for sure, after all she had only been spanked by one person before, now may be two, but Bonnie vividly remembered the first time that Mistress Elena had spanked her and she had been more unsure of herself.
Now she was far more confident, but maybe not this confident. And her smile wasn't quite as sinister, and it was suspicious when she tried to hide that smile whenever Bonnie look back at her. But most suspicious of all was the way that she spanked her.
Normally Mistress Elena gave her more of a playful spanking, unless Bonnie had earned herself a harder butt beating, which wasn't uncommon as Bonnie actually really liked it when Mistress Elena was rough with her.
But then it seemed there was Mistress Elena rough, and then there was Katherine rough, Bonnie crying out louder than ever and tears falling from her eyes as she received the most brutal ass beating of her life.
The doppelgänger wasn't even groping her ass in between spanks, and although she had done that initially she had given it up much sooner than Mistress Elena, which made Bonnie anxious to use her magic to stop this. However she had promised Mistress Elena she wouldn't do that unless she absolutely had too, and Bonnie fully intended to obey that order.
