Her kiss definitely hurt, but it was a good ache. She was taking ownership of him, reclaiming him, marking what was rightfully hers. And he wanted her to, he wanted it to hurt. It was real and raw and he didn't belong to anyone else, and he never wanted to.
"I love you, too. I love you so much," he gasped in surprise as she ripped at his shirt. He moved with her, clinging to her like his life depended on it. He would not lose her, he couldn't lose her. He couldn't be without her now.
He nodded breathlessly, absolutely agreeing to everything she was saying. He knew she was serious, and he had come so close to losing her- he knew what that felt like now, and he was determined it would never happen again. He wouldn't fuck up again, his heart couldn't take it. "I promise. I love you, I never want to hurt you like that. I'm yours, I'm all yours. No one else's, never- I don't want anyone else. You've got me, every bit of me, all of it, always," he told her, breathless from her kisses but steady and determined and serious.
His hands moved under her shirt, fingers gripping and scratching at her skin as his lips crushed hers again, desperate and needy. He'd always felt trapped by commitment. She'd given him permission before to stray as long as he was honest, but now that it had been taken away he was surprised to find that he didn't feel trapped or panicked or suffocated- he felt safe, he felt secure. She loved him. Properly.
