Chapter Four

ISABELLE POV:

Isabelle sat up in bed thinking about love. What did it really mean? She didn't really understand the flutter in her chest when she saw Simon. She didn't understand the movement of her stomach inside. Her heart ached for him constantly, and she couldn't stop thinking about him.

Simon was always on her mind. And the way they had kissed in the alley in the pouring rain made a smile stretch across her face. Yeah, he was a "downworlder" but for some reason, none of that mattered anymore. None of those stupid little details mattered. He was a vampire? So what? Who cared? Not her for sure.

He kisses brought warmth in her heart and his embrace made her feel safe. He brought out the soft and vulnerable side of her and she enjoyed it, but felt weak. Weakness wasn't in her vocabulary and she hated feeling or being weak. Was Simon changing her? She shivered at the thought, but Simon completed her in so many ways. He made her happy and she felt wanted. Yes, she had friends, but were friends enough?

Isabelle sighed and thought about her life with Simon. Vampire/Shadowhunter babies? She chuckled at the thought. Isabelle was getting way too ahead of herself. Her and Simon were dating a hugging and loving.

"Iz, got a second?" Clary said popping her head in the door.

She smiled, "Clary! You stayed!"

She chuckled, "Yup".

"Well don't stand there silly! Get in here".

"I uh... have a favor to ask you...," Clary said blushing.

"Oh my you need something for Jace don't you?" Isabelle said grinning.

"Uh, yeah," she said.

Isabelle squealed, "Let me get dressed!"

CLARY POV:

Clary had never seen Isabelle get ready so quickly. She seemed very excited to help Clary finally gain some confidence and confront Jace.

"Are you planning on tonight or today?" Isabelle asked excitedly.

"Is there an option for a year?" Clary chuckled.

"No! Jeesh, sex is written all over you and Jace. You need to make it happen! Make time. I'll even help you out. I'll get everyone out for a few hours".

" A few hours?" Clary asked semi-excited. A few hours with Jace sounded amazing and the fact that some of it would be taken up by him being her first, and last.

"Yeah, I don't know how freaky you guys will get! I'll take them out to the movies or some crap!"

They reached the store and Clary was embarrassed to even look at it. Isabelle didn't seem to care that they were walking into a lingerie shop. When they walked in a nice lady greeted them and asked if they were looking for anything in particular.

Clary would rather take Isabelle's advice. She grabbed her hand and led her to a corset section.

"I don't know if this is exactly what you're looking for, but maybe you should get a couple. Tease him when you two are fighting," Isabelle said and they both laughed.

"This one is cute," Clary said holding up a white corset that had buttons and lace all over it. It was definately a push up and would drive Jace crazy. White panties were attached to the bottom.

"Ooo that'll drive him nuts! But don't wear it today wear a sexy bra and panties today," she said and walked over two isles, "Oh, over here Clary!"

Clary walked over to her and saw there were rows of sexy, revealing bras and panties. She looked through several and didn't find many she thought would drive him crazy.

"Oh. My. Angel. Look at this," Isabelle said holding up a red bra and panties. It was outlined with black lace and looked like it would push everything up and drive him wild.

Clary decided on that and the white corset. Isabelle got a couple outfits too to surprise Simon after the movie.

"I'm nervous," Clary said as they walked back to the Institute.

"Eh, don't be. You love him, and it'll mean everything later on, trust me," she said smiling.

They got back to the institute and Clary rushed up to Jace's room. Isabelle said she would distract Jace, then say Clary was sick and that he should stay home. Everyone agreed to go see some stupid movie. Simon and Isabelle left together and behind them followed Magnus and Alec. Maryse was already out, she had traveled to Idris to look into something. It would be her, Jace, and their special time. Yeah, she was nervous, but it was for her and Jace and she wanted it to happen. She wanted him to be her first.

JACE POV:

"Where is she?" Jace asked Isabelle.

"Everyone go ahead of me," she said and Jace looked at her in confusion, "She's in your room Jaaaace," she exaggerated his name at the end.

"O...kay," he said and headed for his room. What did she mean by that? Clary didn't feel good, and he was going to hold her and hope she felt better.

When he reached his room he peeped inside and saw she wasn't on the bed, he called out her name, "Clary? You there?"

He heard a rustle from the bathroom and he stepped inside and sat on the bed, "Clary?"

Suddenly, she stepped out and his eyes went wide. His mouth dropped and he couldn't help, but stare. More flesh was showing than usual. She was in a deep red bra that had black straps and was outlined in lace. The top of her panties were right below her waist line, revealing more skin than she usually would have shown him.

She had one arm leaning against the door frame and a leg was crossing the other. She had this sort of sexy smirk on her face, "Hey there," she said and winked at him.

He couldn't manage anything to say and she chuckled. He didn't know if he should get up and go to her or if she was going to come to him. Before he could decide what to do she walked over to him kneeled down him in front of him. She stretched her head up and softly kissed him, "Hey you," and she winked.

He smirked, "Well what a surprise this is," he said.

She ran her hand up his thigh and he smirked more. He couldn't take it anymore and he leaned down and kissed her deeply. It was passionate and loving. She leaned forward more in between his legs and she began to unbutton his shirt. He ran his hand down her back, but she back up, "No, no, no,"

He looked at her with confusion, "Sorry I-"

"No, I'm going to continue what we started yesterday morning. I never finished, you know," she replied and continued to unbutton his shirt.

He just sat there not knowing what to do. He had the love of his life, looking gorgeous and sexy was seducing him, "Clary you don't have to-"

"Shush," she said and put a finger to his lips. She slipped his shirt off and ran a hand down his chest, and stroked it along his pant zipper. She unbuttoned his pants and bit her lip. There was a small nudge from inside his pants. She smiled a little and he sat up a little so his pants would come off.

He sat on the bed in just his boxers and ran her hand along his slowly arousing length. She stood up and he wished she hadn't left. He was so ready for her and to see her. Her innocence mattered, but he wanted to be her first and her last. She stepped close to him and look down at him and smirked, "Wanna do the honors and take this off?" she said and ran her hand along her bra. He decided to play along. He slowly ran his hands along her side and reached around to her bra clasp. He unclasped it and she slid it off. Jace stared at her and wanted to touch her so bad. He looked at her for permission, "Jace, go ahead," she chuckled and leaned closer to him. He pulled her down and crashed his lips against hers his hands explored her body, but again she pulled away and she slipped her panties off.

Now, there was a naked Clary kneeling down and slipping his boxers off.

"I can? Right?" she asked biting her lip.

Jace could only form a nod.

Before he could even realize it, her tongue was slowly making it's way down his length. He leaned his head back and moaned. Just the fact that she was naked and stroking him made him hard. Her mouth slowly formed it's way around him and she bobbed her head up and down.

"Oh shit Clary... Feels so good," he said and moaned in between.

She continued to lick and suck and finally he came.

When she was done she licked her lips, "There, what we started is finished," and she stood up.

He grabbed her by the waist, "Whoa not so fast you,"

She strattled his lap, "Mmm you know, they're gonna be a gone a few hours".

"What if I said no?" he said and smirked.

"Fine I'll just get my clothes-"

Before she could finish he pressed his lips against hers. It was warm and deep, but it turned hungry fast, "I want you Jace Lightwood... be my first," and she whispered the last part. That was enough to arouse him again.

He reached his hand down and slowly rubbed her causing her to moan loudly. He sucked on her neck as he slid one finger into her. She began to scratch his back and it made him want her even more.

CLARY POV:

It felt so good. He had slid two fingers inside her and it felt skin was as close as they could get it and she wanted him. She was nervous, but ready.

He had flipped her on her back and he was on top kissing her deeply. She shuddered and Jace looked at her, "Clary if-"

"Don't I'm just nervous...," she said.

"I'll be gentle, I promise," he said and kissed her softly. It was so tender and loving and before she knew it he had slid inside her.

She winced in pain, "I'm sorry Clary we can stop if it hurts," he said stopping.

She shook her head, "No, don't. It's fine," she said suddenly beginning to feel some pleasure.

After several thrusts they both moaned together feeling the burn and feeling the pleasure tingling through their bodies. He was gentle, but as their kisses deepened he had sped up.

"Oh... Jace" she moaned his name loudly.

They came together and he flopped down next to her. When he caught his breath he said softly in her ear, "I love you Clary".

She kissed him softly and they fell asleep.

*Morning*

Clary woke up without Jace by her side so she headed down the hallway in yoga pants and one of Jace's tees. She was walking down the hall when she heard his voice with Maryse who had apparently gotten back last night.

"Jace, why do you insist on lying to her?" Maryse said.

"I don't want her hurt! One more week, please," he begged.

Clary was confused, but she had an idea on what was going on. Jace had been the one behind it all. He had been that one who coaxed Maryse into keeping her from hunting.

She listened closer.

"Jace, Clary can hunt now, and I will not lie to her anymore," Maryse said sternly.

"Maryse, she's fit to be a shadowhunter but-"

Clary stepped in, "But what?" She said, tears streaming down her face.

Jace just stood there, "Clary-"

"Jace, I'm going home. It's not over but... I need time away... from the liars," she said crying.

Isabelle walked up, "Clary? Go to my room," she said and Clary did as told.

Jace was going to walk after her but Isabelle stopped him, "Jace. Let her alone... Just... I can't believe you would do that..." she trailed off.

"Iz it's not what you think," he replied with sorrow.

"Oh, I know you care. I know you want her safe, but she went through all that training and you take it away from her? Be ashamed Jace Lightwood," and she walked away.

*Later on*

Isabelle walked Clary to the elevator, "You'll come visit me, right?"

Clary nodded with a smile, "Of course".

"And girl's night?"

"Every friday," she replied and hugged Izzy tight.

They exchanged sad glances and Jace walked toward them.

Her smile faded from Izzy and turned a frown toward Jace. She didn't bother saying goodbye, he didn't deserve it.
