This is my first fanfic please rate and review honestly and let me know if I should carry on. Will read all reviews and take suggestions.

I do not own VampireDiaries, nor the characters from it. I do not make any money from the writing of this story.

"What's going on here?" Stefan asked after his brain finally started working again. "Oh nothing really, I was just getting to know your girlfriend a little better, who knew she could be such fun" Katherine said standing up not bothering to cover her nudity. Elena on the other hand quickly seized up the soaked quilt and wrapped it around her body. "Stefan... I... I" Elena stuttered trying to think of something to say.

Stefan rushed into the room at vampire speed grabbing Katherine by the throat and holding her against the wall her feet dangling in the air. "You bitch! How could you do this?" he shouted eyes glowing and fangs bared. Katherine grabbed his wrist, breaking it with very little effort and tossing him across the room.

"Its been fun Elena, we should do this again." She said slowly letting it sink in before rushing downstairs collecting her clothes and slipping a note into Elena's jeans before disappearing out the door.

Stefan rushed over to Elena's side and put his arm round her shoulders, "What happened? Where is your necklace?" He asked concern written all over his face. The fact that he wasn't angry with her and was just concerned and worried about her made Elena feel even worse for what happened. "Urrrr, I don't know, I can't remember." She said acting like she was looking for her necklace. "She must of compelled me, last thing I remember I was in the foyer looking for you. I was worried."

Stefan stood up and started pacing, "I can't believe this, this is a new low even for Katherine. I'm going to kill her, I'm going to kill her" He repeated this over and over again while Elena sat there wallowing in self pity. Part of her was still tingling from the amazing orgasm Katherine gave her making it even harder to hate herself for it.

"I have to go, Jenna will be worried." She said slowly standing up and making her way downstairs. Stefan stood in the doorway to the foyer while Elena slipped on her clothes, "Oh damn she ripped my shirt. Can I borrow one of yours?" Stefan curious face suddenly became a scowl wrapped up in his own thoughts. "Sure" was all he said.

Elena walked into the bathroom turning on the shower before walking into her bedroom, slowly stripping off her clothes. She let out a small scream seeing a silhouette on her bed before quickly turning on the light. "Katherine" She let out a sigh glad she was in no immediate danger, shocked at how quick her opinion of her older doppelgänger changed.

"Hey sweet cheeks, did you get my note?" Katherine asked winking at her. "What note?" She asked twirling around the room looking for it. Katherine stood up and slowly sauntered over to her wiggling her hips seductively. Elena forgot to breath momentarily again expecting Katherine to kiss her as she stood in front of her breaching her personal bubble. Instead she reached he hand being her putting it into her back pocket and pulling out the note, not before giving Elena's firm arse a squeeze.

Elena's eyes fluttered, already getting turned on just from her proximity to Katherine. "This one" Katherine said handing it over before making her way back to the bed and lying along the edge.

Elena read through the note, distracted by the unbelievable beauty of the girl laying on the bed twirling her hair.

Well that was certainly interesting,

I promised I could make you feel things Stefan could never dream of and I always keep my promises.

If I'm not mistaken you never got around to returning the favour.

Another thing I always do is collect what is owed to me. See you tonight. Make sure you're alone.

The prettier doppelgänger.

Elena looked up from the note. Seeing the sly grin on Katherine's face making her angry and suddenly giving her a bout of courage. "Seriously? You expect me to return the favour? By that do you mean abuse you and almost break you up with the love of your life just for my entertainment? You really are a psychotic bitch aren't you" Elena shouted waving the note in the air.

Katherine smiled, slowly getting up and walking over to her. "No, I mean by making me cum like a busted damn while I ride your face like a bitch in heat" she said while Elena blushed a shade so red it could only be called tomato. "I...I...um" She mumbled, squeezing her thighs together trying to hide the obvious effect Katherine's words had on her.

Katherine grinned smelling Elena's arousal in the air. She leaned in and whispered into her neck, "God you smell amazing! Shame its your turn I would love to taste you again" suddenly she leaned back and put on a thoughtful face rubbing her chin "I suppose we could arrange a way that you can return the favour but I still get to taste your amazing cum again" she said in such a sultry way that it called forth a fresh bout of cream between Elena's legs.

Elena gave into temptation and slammed her lips together with Katherine's. Katherine allowed her to be slowly guided over to the bed, Elena lowered her down to the bed falling on top of her never breaking the kiss. Katherine moved her hands down her back grabbing Elena's arse with both hands while Elena bit into her bottom lip so hard she drew blood. Katherine moaned feeling her bloody flowing out of her lip.

Katherine flipped them so she was on top and straddled her waist, quickly disposing of her jacked and top before crashing their lips back together. She undid the button of Elena's jeans and quickly shoved her hand in the opening underneath her panties feeling how wet Elena was. Suddenly this wasn't enough for either of them, both jumping off the bed at the same time removing all of their clothes. Neither took their time, they were too far gone for teasing they just wanted to get straight to it.

Elena shoved Katherine down on to the bed and wrenched her legs apart. Katherine gasped liking this side to Elena, this powerful dominant side. She quickly dropped to her knees and gave a long slow lick with her tongue. Katherine let out a low moan and let her head hit the bed, raking her hands through her hair.

Elena smiled against her pussy, Katherine's cream coating her tongue. She couldn't believe the thrill this gave her, having a powerful vampire at her mercy. Katherine didn't want to moan and didn't want to beg but Elena was doing magical things with her tongue and seemingly keeping her right on the edge of orgasm on purpose. She was shocked that she was showing so much skill for a beginner, but of course she didn't know about that summer her and Caroline spent together exploring each others sexualities.

Katherine let out a feral growl as Elena playfully bit into her clit pushing three fingers inside of her pussy. "Please Elena, please make me cum, please make me cum." She managed to get out between her moans of pleasure. Elena quickly adding a fourth finger and curling them up hitting her G spot. Katherine came instantly and Elena gave her clit a continuous lapping with her tongue.

She kept up the assault bringing Katherine to another orgasm, then another, then another. She couldn't get enough of Katherine's cum, if she had it her way she could of spent eternity on her knees worshiping the goddess in front of her. Which is why she let out a whimper of disappointment when she felt her head being pulled up by her hair, she quickly forgot all objections as Katherine crashed their lips together tasting herself on Elena's tongue.

As quick as it started Katherine broke the kiss and threw Elena back down on the bed, rushing over to her bag by the window. Elena was watching her, enjoying the view of Katherine bent over presenting her with the most beautiful arse imaginable. Then her eyes widened as Katherine turned around with a 10inch strap on dangling from one finger.

"We are going to have some fun tonight" Katherine said with a sultry grin on her face. And slowly began walking back to the bed.

"What's that for?" Elena asked apprehensive staring wide eyed at the huge toy in Katherine's hand. Katherine stopped next to the bed and bent down to slide the strap on up her legs. "What do you think? Its for giving you another orgasm you will never forget." Katherine explained with a mocking smile on her face.

Katherine noticing the look of fear on Elena's face decided to take pity on her. "Don't worry, I'll go slow. If you don't like it tell me and we can stop." Elena relaxed again and was feeling kind of excited to take the 10 inch toy. Stefan was a solid 8 inches, how much difference can 2 inches make?

"Come here" Katherine said kneeling on the bed giving Elena a cheeky wink. Elena just sat there gawking at the amazing beauty that was Katherine with a massive cock around her waist. Elena suddenly regaining her senses got onto her hands and knees and started a sexy crawl towards Katherine. "I forgot to bring any lube, why don't you get this monster ready" Katherine said a mocking smile on her face.

Elena suddenly wary again bent down and slowly licked up the entire length of the plastic cock. Before taking the head into her mouth. Katherine moaned from both the mental stimulation of Elena sucking her cock and the clit stimulator on the other side of the cock. Katherine bucked her hips into Elenas mouth causing her to gag and back off the plastic cock, looking up at Katherine, rubbing it like it was real. "Calm down Katherine, Jenna is round Ricks and Jeremy is at the grill. We've got all night"

Elena resumed the slow blow job swallowing 5 inches straight away. Katherine wrapped her hands into Elena's hair and began slowly guiding her further down. "Relax your throat, don't worry you can take it." Elena did as she was told and relaxed her throat, Katherine thrust in hard sliding another 3 inches down her throat causing Elena's eyes to water.

Elena slid it back out of her mouth resuming rubbing with her hand, "Almost there" She said with a sexy smile on her face driving Katherine crazy. Even though the cock wasn't really hers the blow job getting her unbelievably turned on watching Elena trying to take the entire length.

Katherine suddenly snapped back to reality feeling Elena's nose pressing against her skin. "Mmmmm" Elena moaned around Katherine's cock finally taking the entire length down her throat, she began bobbing up and down trying to get it as wet as possible.

"...That's...Enough.." Katherine said through raspy breaths, she couldn't wait anymore, she had to take Elena. When Katherine started this game she just wanted to cause doubt in Elena's mind about her relationship with Stefan, but now she found herself wanting this more than anything. She didn't care about Stefan, she didn't care about messing with Damon. She didn't even care about getting the moon stone, she just wanted Elena.

"Bend over, spread your legs" Katherine said her dominant side showing again. Elena was apprehensive at first, not wanting to turn her back on someone as dangerous as Katherine. "If I wanted to kill you, you would have been dead as soon as you walked into the boarding house. Now bend over!" Katherine said grabbing her by the hips and forcing her into the position she wanted her.

The ruff treatment only making Elena wetter, this was a side of herself she always repressed when she was with Stefan. She didn't want people to know how much she liked it rough, how dirty her mind truly is. She panted planting her palms onto the quilt and spread her legs even wider, the anticipation killing her. Katherine wasn't done teasing yet, she wanted to drag this out as long as possible, make this Elena's most mind blowing orgasm yet. She rubbed the plastic cocking up and down her pussy not yet entering her.

"Please...now...more" Elena moaned out, she didn't mind begging, not if it meant she would finally get her release. Katherine didn't want to give up that easy, moving it down to her entrance and applying a bit of pressure not yet entering her. Then began the sliding motion again. Elena growled low in her throat, "Please Katherine, please... Ohhhhh Fuck!" Elena screamed Katherine finally forcing the cock inside, pushing 6 inches in with her first thrust.

Elena grabbing fistfuls of the quilt and forcing her arse back towards the intruder. "Ooooh someone's a little eager aren't they" Katherine said with a chucking forcing another 2 inches inside. "Oh god!" Elena moaned. She was surprised by her own reactions, she could never take this much so quick without a little pain, but then again she had never been this wet before. Elena undeniably aroused started rocking her hips back and forth trying to encourage Katherine to move.

Katherine taking the hint set a steady pace thrusting into Elena, occasionally making a circling motion with her hips. Elena was in heaven, but this was too slow for her, she wanted it fast, and she wanted it now. "Faster...Faster" She kept repeating this through her moans of pleasure but to no avail. Katherine kept up the infuriatingly slow place keeping Elena on the edge. "Kath..." was all she managed to get out before she lost her breath letting out a guttural moan. Katherine suddenly picked up the pace and was moving close to vamp speed. She reached around and started playing with Elena's clit at the same time.

Katherine felt her damn break and the floodgates open. Cum started pouring out caking the plastic cock in her essence. Katherine kept up the assult, bringing Elena to one orgasm after another after another. All of a sudden Elena stiffened feeling a digit from Katherine's free hand breach her anus. She pushed it into the first knuckle then the second and started a slow motion bringing it in and out. Bringing Elena to her most powerful orgasm yet, causing her to crash down onto the bed exhausted.

Katherine retracted her hands and then removed the cock from Elena's soaking pussy. "Your not finished yet little Elena, time for you to clean up your mess" Elena looked at her confused until she noticed Katherine look at her mouth down to her cock then back to her mouth again. Elena getting the message slowly got back onto her knees and crawled over to where Katherine was perched and took the cock back into her mouth. She let out a low moan tasting herself on the plastic cock. A wide grin spread across Katherine's face seeing Elena submit to her yet again.

Katherine sat there looking down on her pinching and playing with her own nipples enjoying the view. Elena kept bobbing up and down trying to get as much of her juice as she could loving the taste of herself. After she was was finished and there was nothing left she got up and laid a passionate kiss onto Katherine sharing her taste with her doppelgänger.

Katherine got up off the bed and Elena crashed back down, completely exhausted and fell asleep. Katherine took the strap on off and inserted it back into her bag, getting dressed again before turning her attention back to Elena. She strolled over to the bed, she knelt down and gave Elena a sheepish kiss on the forehead. "Until next time" She muttered before disappearing out of the window.
