Klaus had his hybrids secretly follow Elena everywhere around, when he heard Elena was spotted with Katherine inside of her house, he drops everything and rushes to her. Elena's door was already open as Katherine just left handing her the grimoire and translating the first page in it. He stands at her door and demands, "Invite me in."

Elena was sitting on the dining table staring at the grimoire when she heard his voice. "No" she answers

"You trust her but not me. Of all people you could have been spending your time with you chose to spend your time with her."

Elena gets up and walks towards him slowly while talking to him, "See, Katherine must have done a lot of bad things but you know what she didn't do." Elena stands at the threshold of the door, matches him eye for eye and says, "She didn't faked an engagement with me. She did not sleep right next to me, pressed to me half naked and she did not take advantage of me while I had an accident and took a chance to peep into my body, change me into a patient's clothes and perform a surgery on me which could very well have been performed by a medic."

Klaus grimaces, with inhuman speed he picks up an iron rod shoves it in her stomach and pulls her out. As soon as she is out, he throws the iron rod away speeds away with her, when he stops it is at the rooftop of Tyler's house. Carol had already told him that this was always abandoned only workers would clean it up on the holidays.

He lays Elena down keeping her head on his lap and both her hands locked with his one hand, her legs folded and his one leg over her feet locking her legs in that position.

He bites into his free hand and shoves it on her mouth thus healing and gagging her with it at the same time. "You really have a low opinion of me, don't you Elena?"

"Well let me tell you then, that night when you came to me to make a deal to keep your friends and their family safe and I drained four bags of blood from you. After that you were not quite in the right form love. I did give you my blood to heal you but turned out that you were emotionally breaking from inside."

Elena stops struggling and now is curious to listen to him as he continues further.

"When I came to the room an hour later Elena Gilbert you were murmuring about so much suffering coming on your brother and Bonnie, my blood healed you physically but you were emotionally and psychologically damaged, it was as if you have given up on life, your blood pressure was very high and you were miserable, you could have gotten a stroke by that kind of tension or much worse. They was a fair chance you would have died and I didn't want another human doppelganger, so I called the doctors and they told me they ran out of stock for the meds that could deal with it and the next stock was to arrive by tomorrow evening."

When Klaus notices that now all her attention is on him and she isn't struggling anymore he removes his wrist from her mouth.

"I called doctors and asked for advice and they said that you were falling into depression, seeing your age, the lack of antidepressants and all, the doctors suggested that sometimes cuddling helps cure depression in case of women. You just have to cuddle to her, make her comfortable, make her feel safe, make her feel loved and she will get better and that's exactly what I did."

"So no, I wasn't pressed to your body because I was interested in you sexually, seriously Elena I have seen this face and body for a thousand years what do you have that the others don't." His tone was insulting at the end part.

"Anyway, if I were the monster you claim me to be, I would have compelled a human to take full advantage of you so that I may soon have Petrova babies but I didn't. I didn't trust my female hybrids to control their blood lust while cuddling to a human, all my family was daggered and stolen and your friends were not to be involved in my plans so I cuddled to you all night whispering sweet little things to you, which actually made you better and made you fall asleep. Then my hand touched your vervain bracelet and I got burned. So I took it off of you."

Elena is still lying on his lap, she hasn't noticed that he has removed his leg from over her feet. She hasn't noticed that she has stretched out her legs. She hasn't noticed that she is lying with her head on his lap, the shadow of his face, the only thing preventing the scorching sunlight to hit her face skin and giving her a heat burn. She is too lost in him to notice that his hold has become gentle on her. With one arm behind her shoulders and the other stroking her hair they give the picture of a perfect couple.

He takes a lock of her hair in his hand and plays with it. "You didn't want me to leave Elena, you wanted me to stay. You were the one who insisted that I be with you all night."

Elena has first time notice how beautiful he is, she takes in all his features and has a realization he is more beautiful than any man she has ever seen.

"Well I have a habit to sleep shirtless so I removed my T and slept with you the way you have wanted."

Elena brings her hand up and gently caresses his cheek, Klaus is surprised, "What are you doing?" he asks.

"This" Elena sits up on his lap, cups his face and crashes her lips on him. Klaus is shocked at first, it is the first time Elena has made a move on him without any compulsion involved. It takes him time but he cups her face and kisses her back. They fight for domination lips, tongues teeth collide there is a war for who will dominate the kiss.

It is only when Klaus gets more aroused being a werewolf his hands move down touching her, feeling her, massaging her breasts. Her hands roam his body too to feel each of his toned muscles just as he touches her every curve.

It is only when his hand reaches the hem of her top and he pulls it over does Elena come to her senses and backs away. Realizing what has she doe, she has kissed Klaus, she made out with Klaus on rooftop of Tyler's house.

Klaus stares at her, just as shocked, they both knew they were faking the engagement, they both knew the role Klaus wanted for Elena. He could smell her arousal just as she could see his erection through the bulge in his pants. They look at each other for a minute, Klaus blinks. Throws her top at her and speeds away.

Elena catches the top and looks at the direction he has disappeared to. She wears her top and walks towards the stairs. She swears neither to tell her friends or in this case, her enemies, that what happened between her and Klaus. 'That was just a moment', she thinks, thinks, 'It'll pass.'

Then Stefan's voice echoes in her head, 'Moments are all we've left.'

She breathes three times then tells herself, "Okay, Elena, this was a mistake, I will careful next time, I won't repeat it again." She walks out of the Lockwood Property.
