They lay in the grass among the rubble of the Wayland Manor. Jace lay over her, his body flat against hers, his heartbeat loud in her ears. As debris finally stopped raining down on them, Clary gasped for breath.
"Jace," she said softly.
He drew back slightly, propping himself on his elbows, and looked down at her. Even in the darkness she could see herself reflected in his eyes. "Are you hurt?"
"I'm fine." Without thinking, she reached up, her fingers brushing lightly through his golden hair. She felt him tense, his eyes darkening.
"There was grass in your hair," she said. Her mouth was dry; adrenaline sang though her veins. She rested her hand against his cheek.
Jace just continued to look at her. After a few seconds, Clary asked, "What are you thinking?"
"About my feelings for you," he replied softly, almost to himself.
Her eyes widened, shocked. "What do you mean?"
He was silent for a long moment, staring down at her. "You're my sister," he said finally. "My sister, my blood, my family. I should want to protect you- protect you from the sort of boys who want to do with you exactly what I want to do."
Clary's breath caught. "You said you just wanted to be my brother from now on."
"I lied," he said. "There are some kinds of wounds you can get when you're a Shadowhunter- internal injuries from demon poison. You don't even know what's wrong with you, but you're bleeding to death slowly inside. That's what it's like, just being your brother." His voice turned lifeless. "God knows I tried, but I don't want anyone but you. I don't even want to want anyone but you." He trailed his fingers lightly through her hair, fingertips brushing her cheek.
Clary's voice sank to a whisper. "I don't want anyone but you either."
She was rewarded by the catch in his breathing. "No more pretending," he whispered. "I love you, and I will love you until I die, and if there's a life after that, I'll love you then."
Clary's hand slid along his cheek. "I love you, too," she breathed.
At her words, his expression changed- there was a look on his face she'd never seen before, a sleepy, almost deadly light in his eyes. He let his fingers trail down her cheek to her lips, outlining the shape of her mouth with the tip of a finger. "You should probably tell me not to do this," he said.
She said nothing. She didn't want to tell him to stop. She was tired of saying no to Jace- of never letting herself feel what her whole heart wanted to feel. Whatever the cost.
He bent down, his lips against her cheek, brushing it lightly- and still that light touch sent shivers through her nerves, shivers that made her whole body tremble. "If you want me to stop, tell me now," he whispered. When she still said nothing, he brushed his mouth against the hollow of her temple. "Or now." He traced the line of her cheekbone. "Or now." His lips were against hers. "Or-"
But she had reached up and pulled him down to her, and the rest of his words were lost against her mouth. He kissed her gently, carefully, but it wasn't gentleness she wanted, not now, not after all this time, and she knotted her fists in his shirt, pulling him harder against her. He groaned softly, low in his throat, and then his arms circled her, gathering her against him. All that existed was Jace- all she felt, hoped, breathed, wanted, and saw was Jace. Nothing else mattered.
She could feel the heat of him burning through his clothes and hers. She tugged his jacket off, and then somehow his shirt was gone too. Her fingers explored his body as his mouth explored hers: soft skin over lean muscle, his scars like thin wires, a map of a life of endless war.
Jace unbuttoned her coat, his fingers trembling. Pulling back for a moment, his tawny eyes met her green ones. Sliding his hands slowly up her sides under her sweater, he brushed his lips over hers, lightly at first, and her own opened automatically beneath the pressure. With a soft moan, she twined her arms around his neck, her hands knotting in his hair, and the kiss stopped being gentle and became fierce, all in a single moment like tinder flaring into a blaze.
Her sweater bunched beneath her breasts as Jace softly slid his hands over her bra. The front clasp came free on the third try, and Clary gasped when he grazed her distended nipples with his fingertips. His mouth moved over her jaw to her throat, leaving a trail of fire in his wake. Clary moaned, her nails raking gently down Jace's back, making him arch against her, his middle meeting hers unexpectedly.
They both stilled as their breath stuttered out on gasps. Jace was pressed intimately between Clary's legs, her ankles locked at the base of his back, his hands still beneath her shirt.
Pressing his forehead to hers, Jace murmured, his breathing ragged against her lips, "If we don't stop now, I don't know if I'll be able to later."
Burying her hands in Jace's golden curls, she pulled his mouth to hers. "I don't want to stop," she whispered. "I want to be with you. Forever."
How could he deny her? He didn't care if she was his sister- he'd fallen in love with her before they'd ever been told. He had his doubts about the truth of it. After all, he looked nothing like Valentine, nothing like Jocelyn. Clary looked exactly like her mother, with her red hair and emerald eyes- where had his tawny hair and eyes come from? They couldn't be siblings.
Unable to take the torture of her against him, he parted her lips with his tongue, kissing her passionately before ripping his mouth from hers and asking between clenched teeth, "Where?"
Clary pulled his stele from her back pocket. "At home."
A few moments later, they walked out of the portal and into the courtyard on the side of the Institute. When Jace hesitated, Clary took his hand and led him to the front door. Pressing her hand against the wood and meeting his eyes, she whispered, "In the name of the Angel, we ask entrance-"
The doors swung away from her hand, opening to the dark foyer. With a smirk, Jace took the lead, starting the elevator as soon as they were inside. Clary leaned against his side, content, confident in her choice. There was no going back now. She had made the decision to be with Jace, no matter what, and she was going to follow through.
When the elevator stopped, Jace wrapped his arm around her shoulders and led her down the hall to his room. He opened the door and Clary sighed. It was still spotless and bare except for the furniture.
"What?" Jace asked as they entered, shutting the door behind them.
"I'm going to take some pictures and put them in this room," she said thoughtfully. "It's so impersonal in here." She shook her head and smiled up at him sheepishly. "Sorry."
He said nothing, just cupped her cheek while his eyes showed how deeply he appreciated her attempt to make his room homier. He leaned down and kissed her lips softly. Leaning his forehead against hers afterward, he stroked his hands into her red hair. "I want a picture of us by the bed. Otherwise, I don't care."
"I'll get a camera as soon as everyone gets back from Idris," Clary breathed against his lips, distracted. She felt him tremble as she stepped closer to him.
When their bodies touched from shoulders to toes, Jace knew he couldn't take any more. His hand slid over her hip as the other tangled in the curls at the nape of her neck, pulling her mouth to his roughly. His tongue parted her lips, mimicking his desires, the sweet sound of Clary's elated gasp swallowed by his passionate onslaught. Clary wound her arms around his neck, pressing herself as close to him as possible. His hand slid under her shirt again, shoving it out of the way as his mouth left hers to travel down the column of her neck. Gently massaging her breast, he walked her to his bed.
Clary disentangled herself from him long enough to shuck her coat, sweater, bra and shoes, discarding them into a pile on the floor before she crawled onto the bed, lounging against the pillows patiently.
Jace quickly followed suit, his clothes and footwear joining hers. Clad only in his jeans, he lay down next to her and pulled her back into his arms.
Their tongues fought for dominion as they explored each others' bodies. Clary moaned against his mouth when he weighted her breast in his hand again, flicking his thumb over her nipple. When her hand came dangerously close to his top button, he grabbed her wrist and pinned it above her head, laying half over her. His eyes warned her that his control was slipping.
Biting her lip, she rolled until she was straddling him, the delicious heat of his arousal pressing against her womanhood. Jace growled, gripping her hips.
Curious, Clary shifted, rubbing her femininity against his manhood. Jace reacted accordingly, his hips lifting to grind against hers. Her eyes fluttered shut at the sensation of having him beneath her like this.
Her power, however, was short-lived. Before she could guess his intentions, Jace was completely over her again, fitted snuggly between her legs. He kissed her, hot and hard, before his lips traced a trail down her neck, over her nipples- both treated to a wicked tongue lashing- and lower. Clary threaded her hands through his hair, the curls twisting around her fingers.
Jace kissed along her pant line as he undid them. His tongue dipped into her navel as he pulled the offending garment down her legs and off, leaving her in a plain pair of boyshort panties.
Breathing raggedly and barely holding on to his tattered wits, Jace looked up at Clary. Her eyes were half-lidded, the movement of her chest erratic. She was the most gorgeous thing he'd ever seen.
And she was his.
Holding her gaze, he slid his hands up her thighs. She gave a stuttered moan in anticipation. Using his thumbs, he parted her folds and blew a stream of air along her slit. Clary arched in reaction, her grip on his hair tightening. He did it again, a cocky smirk curving his mouth as Clary's eyes rolled back in pleasure. Finally, he moved her panties aside to see her treasure.
She was pink and swollen, her labia shimmering with juices. Unable to suppress the urge, he slid a finger into her, biting down hard on his lip when she arched up, her paradise hot and tight around his digit. He slowly stroked her, gritting his teeth against his own need. Without any coaxing, she began to move her hips as he added another finger, riding his hand with abandon.
The mental image of her riding another part of his anatomy proved to be too much. His digits moving faster within her, Jace lowered his mouth to her most intimate place, his tongue teasing her clit as his unoccupied hand undid his pants and slid them off.
Needing her painfully, Jace sucked her clit into his mouth, flicking it with the tip of his tongue. Clary's moans became sobs of ecstasy, her hands gripping his hair.
"JACE!" Clary screamed as her walls contracted around his fingers. He watched her in fascination as she came, noting her clenched eyes, flushed skin, and her erratic breathing.
When she was done, Jace crawled up her body to kiss her. "I love you," he whispered tenderly against her temple, feathering kisses over her face.
"I love you, too," Clary answered in a soft, breathless voice. Then her hand slid down his chest and between them, her fingers curling around his erection…
