Her eyes shimmered, and before he could wonder for more than a moment whether it was with tears, he had leaned forward and kissed her. This time it wasn’t awkward. This time she leaned into him, and he was suddenly under her, rolling her on top of him. Her long black hair fell down around them both like a curtain. She whispered to him softly as he ran his hands up her back. He could feel her scars under his fingertips, and he wanted to tell her he thought of them as ornaments, testaments to her bravery that only made her more beautiful. But that would have meant stopping kissing her, and he didn’t want to do that. She was moaning and moving in his arms; her fingers were in his hair as the two of them rolled sideways, and now she was under him, and his arms were full of the softness and warmth of her, and his mouth with the taste of her, and the scent of her skin, salt and perfume and… blood.
He stiffened again, all over, and Isabelle felt it. She caught hold of his shoulders. She was luminous in the darkness. “Go ahead,” she whispered. He could feel her heart, slamming against his chest. “I want you to.”
He closed his eyes, pressed his forehead to hers, tried to calm himself. His fangs were back, pushing into his lower lip, hard and painful. “No.”
Her long, perfect legs wrapped around him, her ankles locking, holding him to her. “I want you to.” Her breasts flattened against his chest as she arched up against him, baring her throat. The scent of her blood was everywhere, all over him, filling the room.
“Aren’t you scared?” he whispered.
“Yes. But I still want you to.”
“Isabelle—I can’t—”
He bit her.
His teeth slid, razor-sharp, into the vein at her throat like a knife slicing into the skin of an apple. Blood exploded into his mouth. It was like nothing he had experienced before. With Jace he had been barely alive; with Maureen the guilt had crushed him even as he had drunk from her. He had certainly never had the sense that either of the people he had bitten had liked it.
But Isabelle gasped, her eyes flying open and her body arcing up against him. She purred like a cat, stroking his hair, his back, little urgent movement of her hands saying Don’t stop, Don’t stop. Heat poured out of her, into him, lighting his body; he had never felt, imagined, anything else like it. He could feel the strong, sure beat of her heat, pounding through her veins into his, and for that moment it was as if he lived again, and his heart contracted with pure elation—
He broke away. He wasn’t sure how, but he broke away and rolled onto his back, his fingers digging hard into the mattress at his sides. He was still shuddering as his fangs retracted. The room shimmered all around him, the way things did in the few moments after he drank human, living blood.
“Izzy… ,” he whispered. He was afraid to look at her, afraid that now that his teeth were no longer in her throat, she would stare at him with revulsion or horror.
“What?”
“You didn’t stop me,” he said. It was half accusation, half hope.
“I didn’t want to.” He looked at her. She was on her back, her chest rising and falling fast, as if she’d been running. There were two neat puncture wounds in the side of her throat, and two thin lines of blood that ran down her neck to her collarbone. Obeying an instinct that seemed to run deep under the skin, Simon leaned forward and licked the blood from her throat, tasting salt, tasting Isabelle. She shuddered, her fingers fluttering in his hair. “Simon…”
He drew back. She was looking at him with her big dark eyes, very serious, her cheeks flushed. “I…”
“What?” For a wild moment he thought she was going to say ‘I love you,’ but instead she shook her head, yawned, and hooked her finger through one of the belt loops on his jeans. Her fingers played with the bare skin at his waist.
Somewhere Simon had heard that yawning was a sign of blood loss. He panicked. “Are you okay? Did I drink too much? Do you feel tired? Are—”
She scooted closer to him. “I am fine. You made yourself stop. And I’m a Shadowhunter. We replace blood at triple the rate a normal human being does.”
“Did you…” He could barely bring himself to ask. “Did you like it?”
“Yeah.” Her voice was husky. “I liked it.”
“Really?”
She giggled. “You couldn’t tell?”
“I thought maybe you were faking it.”
She raised herself up on one elbow and looked down at him with her glowing dark eyes—how could eyes be dark and bright at the same time? “I don’t fake things, Simon,” she said. “And I don’t lie, and I don’t pretend.”
“You’re a heartbreaker, Isabelle Lightwood,” he said, as lightly as he could with her blood still running through him like fire. “Jace told Clary once you’d walk all over me in high-heeled boots.”
“That was then. You’re different now.” She eyed him. “You’re not scared of me.”
He touched her face. “And you’re not scared of anything.”
“I don’t know.” Her hair fell forward. “Maybe you’ll break my heart.” Before he could say anything, she kissed him, and he wondered if she could taste her own blood. “Now shut up. I want to sleep,” she said, and she curled up against his side and closed her eyes.
Somehow, now, they fit, where they hadn’t before. Nothing was awkward, or poking into him, or banging against his leg. It didn’t feel like childhood and sunlight and gentleness. It felt strange and heated and exciting and powerful and… different. Simon lay awake, his eyes on the ceiling, his hand stroking Isabelle’s silky black hair absently. He felt like he’d been caught up in a tornado and deposited somewhere very far away, where nothing was familiar. Eventually he turned his head and kissed Izzy, very lightly, on the forehead; she stirred and murmured but didn’t open her eyes.
