Isabelle woke opening her eyes, only to immediately shut them due to the golden, blinding light that shined brightly through her window, indicating that it was morning. She was snugly wrapped in someone's arms. She turned to see it was in fact Simon. This is like the third time I have spent the night with the same person, she thought to herself watching as the light illuminated his skin showing very colored, very alive skin. Not surprised Isabelle realized that Simon was asleep. Whenever she watched a movie where a couple slept together it had always been the girl of the two to wake up first. Who knew that actually happened, she thought to herself. Though they both needed to get up for breakfast then, early morning training, she wanted to just lay near him and his soft steady breathing, and watch him sleep. After watching him for a few long minutes she began to move closer to him, still snuggled in his arms, to lay her head on his bare chest, until she realized that they were both still very naked. Almost instantly she jumped out from his arms and on to the floor searching for any scratch of her clothing to put on before someone saw her body. Too late. The shock from her quick movements from the bed caused Simon to jolt up right, eyes wide open, and see an embarrassed looking Isabelle on the floor. He realized what she was doing and snickered a little, waiting for her to find her under wear and put them on. She finally found her underwear and bra and began to stand to put them on when she saw Simon's big brown eyes staring at her intensely. She immediately closed her legs and put an arm over her chest and turned, "CLOSE YOUR EYES IDIOT!" Before she had turned Simon could have sworn he'd seen Isabelle blush. Confident it was just his imagination, he obliged and put one hand over his eyes.

"Okaaaay. They're cloooosed", he said jokingly and a little mockingly that made Isabelle furious. She proceeded in putting on her clothing that were sprawled out over her pink rug and under some of Simon's clothes. She finished and walked over towards Simon and instructed him to open his eyes. As he did she planted a right fist directly on to his nose, causing a screeching sound of pain protrude from Simon's mouth. "Why'da do that?", he grunted.

Isabelle simply smiled saying, "Let's just call that a preview of what training is going to be like today after breakfast", she paused, "since I am going to be the one training you. Oh, and if you ever mock me again, you will be lucky if that's all you get. OKAY?".

"Okay, okay", Simon said leaning his head back while holding onto his nose. He could not help but wonder if 'this" was just a preview how much hell he would have to suffer in actual training.

Isabelle looked down at him and crawled onto the bed, like a cat, and positioned herself over him, not caring that he was still exposed under her comforter. She removed her hands from his face and kissed his nose softly, then went down to his mouth. "You know I love you right?"

"You have a funny way of showing it", Simon said jokingly; which caused a laugh out of Isabelle. She loved the way he made her laugh. She stood and told Simon he should get dressed as she waited out in the hall for him to finished.

When he was done he walked out of the room only to find Isabelle and Alec in the middle of a conversation, which he thought was about the kind of body wash called Sandle Wood. Alec immediately looked up as he Simon walking out buckling up his belt that lay undone around his waist. The few seconds it took for Alec to realized what Simon and Isabelle had done, was like hours to Simon. He stood there frozen staring at Alec with his hands still gripping his belt anticipating what Alec was going to do. The next moments were a daze to Simon. One second he was anxiously standing up right and the next he was on the ground being strangled by and enraged older brother. He had guessed Alec had lunged at him at some point but could not recall when. Simon heard a mixer voices one yelling at Alec, trying to get him to stop, and the other directed towards him.

"WHAT DID YOU DO TO MY SISTER!" Alec screamed. Loud screams jumped out of his mouth, which caused both Clary and Jace to rush out of each others' rooms and towards the commotion in the hall.

"What the hell," Jace said pulling Alec off of Simon, causing a choking and coughing sound to escape Simon's throat. "I hate the guy as much as the next, but even I have the restraint to not choke the guy." Jace said almost laughing.

"This is not funny, Jace. He violated our sister. he made her have sex with him." Alec said glaring and pointing at Simon.

Fed up Isabelle yelled," He did not makeme do anything, no one can. And I was the one who pressured him to do it."

Surprised Isabelle heard a little gasp escape everyone's mouth almost in synchronization, which just annoyed the hell out her. She grabbed Simon by the arm, pulling him up, and carried him back into her room, into her bathroom. Out in the hall Jace was trying desperately to stop himself from laughing, for Alec's sake. Clary saw this and punched his shoulder, hard, dragging him into her room. Alec stood there in awe, then when he got his bearings he rushed into his room, grabbing a towel to dry his wet hair, and pulling out his cell phone.

Isabelle had a wet towel and was gently touching Simon's neck and nose with it attempting to ease the bruises that had already begun to form, in both places.

"You Shadow Hunters are something else", Simon said rubbing his throat, "I hope every morning isn't this exciting."

"Oooh, don't you," Isabelle said provocatively, and Simon immediately knew she was referring to the "way" they both woke up. Nuzzled together naked in bed.

"Well maybe that part wasn't so bad."

"If you want that part then you're going to have to accept all the other parts too, pleasure or pain. Is it worth it?"

Simon thought for like a split second then shook his head "yes", causing a smile to form across his face. She smiled back and kissed him on his now easily seen bruises, then on his mouth. The kiss was long and soft. Isabelle grabbed his hand and led him out of the bathroom and out of her messy room towards the steps.

"Let's go eat breakfast. I can make a mean omelet."

I have to stop this one here guys due to time. I will be continuing this story whenever I get the chance to. Keep reading and reviewing, really appreciate it. Thanks!
