When I had seen the vista previa for The cena Guest, I couldn't resist playing on it, but instead of Katherine always mimicking Elena I decided that Elena would try to pass herself off as Katherine for a change. And passing herself off as Katherine she would give in to getting together with Damon.
dado the content of some of this I would have to rate it MA. Hope tu enjoy :)

Elena Gives in to Her Naughty Side

Elena came into the study to catch Katherine doing her best impression of her. As Katherine, Damon and Stefan caught sight of her the all fell silent.
“Wow. I’m getting really good at this,” Katherine mused.
“Yes, and aren’t we all just the happy little family? We put the fun in dysfunctional.” Damon sneered.
“You’re not helping here, Damon. Shouldn’t tu be off compelling some helpless girl?” Stefan snapped.
“Oooh, touchy are we? What’s the matter, Stefan, jealous that tu could never compel anyone as well as I can?” Damon taunted.
Stefan dicho nothing but gave Damon a hostile glare which bought out a sharp, sarcastic laugh from Damon.
“Boys, boys. Come on, we need to go through these old journals if we want to defeat Klaus. Oh, and there are a lot of things Damon’s good at. A LOT.” Katherine dicho emphasizing the latter part of her statement while looking directly at Elena, who blushed furiously and looked away.
Elena snuck a glance in Damon’s direction and found his eyes boring into hers like blue lasers and raised his brows and smirked suggestively at her.
As the group delved into the boxes of journals, Elena left the room to get herself a glass of water. She was annoyed because Katherine constantly pretended to be her and now she saw first hand how she played the two men into her hands. Angrily she clattered around the glassware and grabbed a glass filling it with water. She didn’t hear Caroline slink in behind her.
“You know, two can play at that game,” Caroline dicho which caused Elena to jump and turn in her direction.
“What?! Pretend to be Katherine?!” She asked feeling a amargo, amargos taste in her mouth from the mere thought of pretending to be a manipulative perra like Katherine.
“Yeah, why not? She’s always pretending to be you. Why not do the same? Have some fun with it,” Caroline dicho matter-of-factly.
“How do I do that?”
“Study her. Study her manner, the way she moves, and how she talks. Just get in touch with your inner perra and your inner slut,” Caroline dicho with a wicked grin. “Come on, Elena, tu know it’ll be fun. Besides, if the worse happens with Klaus at least tu will have had some adventure.”
“Oh, come on, Caroline. I could never…,” she started.
“Oh, yes, tu can! And don’t tell me that tu haven’t ever wondered how Damon was in between the sheets. I’ve seen the way that tu two look at each. It’s so obvious!” Caroline burst out.
Elena gaped and turned red but as she was about to protest that it wasn’t true she knew that it would be a lie. Ever since she had gone to Georgia with Damon and heard Bree’s comentario about Damon’s bedroom performance she was más than curious.
“Fine,” she said. “I’ll give it a go, but say nothing to Stefan. NOTHING!”
“Mum’s the word. I know nothing.” Caroline grinned and sauntered off.
The siguiente night she decided to enact her plan. She took off her vervain collar and replaced it with a lapis lazuli one Caroline had found for her. She went to the boarding house and found no one there at the moment and thought, ‘Here goes nothing’ and headed up to Damon’s room.
She stripped off all of her clothes and went into Damon’s shower. Just as she started to revel in the feel of the hot water on her skin, she heard the bedroom door close. She turned and saw Damon standing there gaping at her. He didn’t seem at all surprised but in fact, almost looked annoyed. She closed her eyes for a moment and thought, ‘Courage’ and willed herself to play the part of seductress.
“Ah, Damon, so nice to see you. Care to registrarse me? The water’s still hot and it would be an awful same to waste it alone. Come on, tu know tu want to and so do I,” she purred in her best Katherine impression.
He hesitated for a moment but then stripped off his clothes. She looked at him feeling her blood run hot. ‘God, he was hot! And huge!’ she thought as she trailed her eyes down his body. He came in the ducha, ducha de and wrapped his arms around her nuzzling her neck. Elena gripped his arms and forcibly pushed him up against the muro and gave his neck a little playful nip. She also boldly reached down and fondled his long erection which only grew harder in her grasp. He let out a growl and with vampire speed he switched positions pushing her up against the muro and brought his mouth down firmly and possessively on hers.
“Mmm, you’re eager tonight, Damon,” she drawled seductively. All the while her corazón was pounding a staccato in her chest.
“Always. tu should know that. That’s why tu always came running back to me,” he smiled against her mouth.
“Oh, yes, and don’t I know it and amor it?! Take me! Take me now, Damon!” she demanded as she gripped his butt feverishly.
He gave a little chuckle and said, “As tu wish,” and lifted her up por her butt and impaled her onto his erection. Elena gasped from the shock and his size but dicho nothing that would blow her ruse.
“Oh, yes! tu know how I like it!,” she screamed , running her hands through his hair.
He took her hard and fast driving into her with all of his pent up need. Elena began to swoon from the intensity of it. God, the sensations he was making her feel! She soon felt a sensation building within her and soon after felt her orgasm thunder through her with such force she screamed, yelling out his name.
Damon drove into her más demandingly and then bit into her throat taking her blood as he spilled his violent release into her. Elena moaned in pleasure again. She felt herself begin to drift in and out of consciousness until all went black and fell adelante, hacia adelante limply onto Damon.
Damon froze and withdrew his fangs and from between her legs and laid her down on the ducha, ducha de floor. Shock and fear consumed him. This was not Katherine; it was Elena. He had been so sure it was Katherine in his ducha, ducha de again that he didn’t pregunta it. She even acted like Katherine to the tee. God, he even made amor to her! Katherine would not have blacked out from his bite. They always bit each other during sex because it intensified the experience. It should’ve tipped him off when she didn’t bite him during her release.
Quickly, he bit his wrist and brought it to Elena’s mouth. “Elena! Elena! Drink!” he urged as he patted her cheek.
She stirred and came to and complied with his wishes. When she felt better she looked up at Damon who was hovering over her in all his naked glory. “Woo, boy!’ she thought groggily. Then she noticed the water was off.
“What sort of twisted game are tu playing, Elena?” he asked sternly.
“No game,” she rasped. “I wanted to get back at Katherine por pretending to be her for once.”
“Yeah, well, tu nearly got yourself drained dry because of it. And what was I; your test run?” he snapped.
“I didn’t hear tu complaining a little while ago,” she snapped back.
His eyes widened and his dark brows shot up but he quickly composed himself and dicho smugly, “If tu wanted to sleep with me, Elena, tu didn’t have to pretend to be anyone. Least of all, her.”
She gasped in shock and he grinned wickedly from her reaction and added, “If I knew it was you, I wouldn’t have been so rough.”
Her face instantly infused with heat and she looked away from him hearing him chuckle.
“I didn’t hurt you, did I?” he asked softly now.
“No, I’m okay. I was just surprised por your…I mean, when…,” she stammered because she was too embarrassed to tell him just where exactly she hurt. He didn’t believe her but didn’t press the issue. Instead he stood up grabbing some towels for them. After he wrapped one around himself he enveloped her in one and scooped her up into his arms and brought her to his cama setting her in the center of it.
“Does St. Stefan have any idea of this little charade of yours?” he asked. She shook her head. “Well, okay. I’ll go get tu some clean clothes.” Then he gently kissed her forehead and got up.
When he returned she noticed he was dressed and had some of Katherine’s clothes in his hands which he placed siguiente to her.
“What made tu do this? Why this whole charade?” he asked.
“Because I may die when Klaus comes and I wanted to know what it was like…to be with you,” she dicho softly.
Shock overwhelmed him. “Elena, tu never needed to pretend to be anyone else to know that,” he told her.
“Yes! Yes, I did! tu would’ve always done the honorable thing and turned me down to not hurt Stefan. You’ll deny that but I know it’s true. You’re better than tu think tu are. The only way you’d take me up on my offer was for me to pretend to be Katherine. She’s always pretending to be me, so it’s only fair. Besides, it was a lot of fun.”
“Elena, I would’ve taken tu up on your offer as yourself if I had thought tu were sincere. No game was necessary,” he told her.
“Well, I’m sincere now and if it helps, tu can pretend I’m Katherine again and do as tu will,” she dicho with a mischievous grin.
He made a grim expression and shook his head. “It’s not Katherine that I want.”
“Well, it certainly seemed that way a few minutos hace in your shower. No one makes amor to someone like that if they didn’t want that person,” she dicho saucily.
“Silly, Elena. Don’t tu know anything about me yet? That’s because I was pretending it was tu in my mind while I was using what I thought was her body,” he retorted.
“Oh!” she gasped. Clearly she could see in his eyes that he still wanted her. “Well, in that case, here I am. Do what tu will with me.”
“I don’t want a brief fling, Elena! Nor do I want pity sex! If I’m going to have tu at all, I want all of you. Not some part-time get togethers for illicit sex when Stefan’s not around! It’s all of tu o nothing at all!”
She sat up at that point and brought her hand to his cheek forcing his gaze on hers. “I’m not talking about a brief fling, pity sex o brief get togethers, Damon. Now, please, just make amor to me,” she breathed.
“I’m serious, Elena. No games. You’re either all mine o not at all. Not with Stefan and then with me when he’s not looking o around. I’m not going through this damnable pain again!” he dicho firmly.
In response to his statement she laid back on the cama and pulled open the towel baring herself to him. He looked at her and instantly felt his desire flare up. So without further hesitation, he stripped off his clothes swiftly and came over her positioning himself.
“Remember, no games, Elena,” he warned.
“No. No games. I want to be with tu as myself. I can’t keep fighting it anymore,” she whispered as she parted her legs for him.
He moved in between her legs poised but instead of giving her what she so desperately wanted he instead brought his mouth down tenderly on hers. She returned the kiss and grew más passionate and at the same time she trailed her hands down his back and cupped his butt. She tugged at him eagerly but he was immovable. He wanted it on his terms. After another agonizing minuto she felt him lower himself between her thighs pushing them further apart and entered her in a rápido, swift but gentle stroke. She cried out.
He then masterfully and tenderly made amor to her. She felt waves of pleasure building within in and couldn’t believe what an amazing lover he was. Bree wasn’t exaggerating! He was definitely rocking her world. Part of her almost felt guilty for not feeling this way with Stefan but that couldn’t be helped. Damon was por far a más superior lover than Stefan.
Damon kissed her with más passion and increased the tempo. Elena let out a loud cry and screamed out his name as her release roared through her. Damon followed shortly after her and groaned out loud giving her a kiss afterwards.
They fell apart panting and Elena snuggled siguiente to him resting her head on his chest. He wrapped his arm around her possessively and they lay peacefully for a while. He couldn’t believe what had just happened between them. Elena looked at him and rolled on parte superior, arriba of him bringing her lips to his. Her tongue delved in his mouth and she felt him respond with fervor and moved to straddle him. Just as she was about to initiate another gratifying round of sex they were distracted from their reverie por Stefan calling out for her.
The bedroom door opened and Stefan came in asking, “Damon, have tu seen…” but stopped abruptly when he saw Elena straddling Damon’s hips. He stood gaping at them.
Elena moved off and drew the sheets over them drawing close to Damon’s side. “Do tu mind? Damon and I were a little busy,” she dicho testily in her Katherine impression.
“Yes, Stefan, Katherine and I were otherwise occupied until tu rudely interrupted,” Damon dicho with annoyance.
“Katherine? Are tu so sure of that?” Stefan asked.
“Yes!” Damon answered.
“Really, Damon? Funny, since I’m right here with Stefan, so how can I also be in cama with you? Not that I would mind, of course,” Katherine dicho as she walked in behind Stefan.
“Damon, would tu care to explain yourself?” Stefan asked.
“What’s to explain, little brother? I think what I was doing should’ve been obvious to you. Unless, however, tu need me to teach tu all about the birds and the bees,” Damon taunted.
“Oh, come now boys. tu know that I was never able to choose between tu which is why I turned both of you,” Elena purred playing her role as she ran her hands over Damon’s sculpted chest and through his hair.
At that Katherine’s brows shot up. “Well, well,” she mused. “Who’s the good actress now?”
“Oh, tu tell me, Elena, dear?” Elena shot back.
Stefan’s head was reeling now. Which one was really which? Was it really Elena sleeping with Damon o was it Katherine? “Wait!” Stefan interjected. “What’s going on here? I’m pretty sure I was in the study with Katherine since she’s not wearing the locket, which I also see tu don’t have one either.” His brow furrowed in confusion.
Damon looked over at Elena in surprise. He hadn’t even noticed. She could’ve been compelled but he would never compel her because he wanted her feelings to be sincere. ‘Clever,’ Damon thought.
“Well, who is who?” Stefan demanded. Damon burst out laughing which got him rewarded with a nasty glare from Stefan.
“Well, there’s only one way to find out,” Katherine dicho and sped at Elena with vampire speed and flashed her vamp face.
When Stefan saw this he looked beyond angry, then distraught and walked out of the room.
Katherine recovered and said, “Wow! Kudos to you, Elena. Nicely done. That was almost convincing except for the not being a vampire part.” Then she looked over to Damon and said, “I hope it was all worth it, Damon. I know I’ve dicho it before but, when did tu get so hot? You’re so much hotter than tu were! Back then tu were so sweet, so tender, and so…human. What a bore! Now you’re más ruthless and so much más badass! That’s so HOT! Obviously tu and I have más in common than tu think.”
Elena looked shocked. Damon used to be más like how Stefan is now? Before she had the chance to really let that thought set in, Damon responded to Katherine nastily.
“There’s where you’re wrong, Katherine. I can truly amor someone. tu could never. You’ve never been able to amor anyone else but yourself. Besides, tu still want Stefan and told me that again más recently if tu recall. tu didn’t care enough about me then and tu certainly don’t now,” Damon spat venomously.
“Oh, nonsense, Damon. tu were gorgeous and obviously still are. I had to have tu too. If I truly felt nothing at all, tu wouldn’t be here now, you’d be long dead,” she told him.
“Well, why then? Why did tu turn me at all? So tu can eternally torment me?” Damon demanded.
“Well, besides being so hot. tu definitely knew your way around a woman. tu were por far so much better in bed. I bet you’ve dropped millions of panties in the last few centuries. And now, Elena knows that too,” Katherine purred.
Elena blushed deep to the roots of her hair and sunk further under the sheets and closer to Damon. He looked over at her and drew her in his embrace.
“Oh, once you’ve had a taste of Damon’s loving, Elena, you’ll forever be hooked on him. Why do tu think I came back? That was one reason,” Katherine dicho with a wicked grin before leaving.
