This is a bad idea 

It was very carefree. This moment, she was laughing at him and he was laughing at himself as well. She was sitting on him casually like she did that often. Never mind the fact she was naked on top of him. He continued to let his hands trace along her body and kissed her back. Rory glanced at her and fuck, he hated her at that moment. The way she made his heart race, even after two years he couldn’t control that feeling she gave him. His own hips lifted to meet hers and he watched as she slid onto him. His hand moved to her cheek as she lowered herself down, his eyes screwing shut at the feeling. She was tight and it was feeling that he was focusing on so he wasn’t to end things too soon. He didn’t move, his hips were lifted up to hers, but he didn’t move. He waited until she was ready and let her relax against him for a second. “Okay?” He asked as his fingers ran down her back slowly. He kissed the side of her head and waited until she was ready.

Harmony let out a small breath, moving her hands to grip his shoulders as she lifted her head. “Yea, I’m good,” she nodded, smiling and then kissing him again, rocking her hips experimentally. There was a small twinge of pain, but it faded quickly and Harmony’s breath caught in her throat, thrown off slightly. It wasn’t as though she was totally oblivious, she knew the mechanics, but she’d never imagined it would be this… acute. She opened her eyes again, given that they had fallen half shut, and was astounded by how surreal this was. Harmony contemplated for a second why she’d given in here, and now, though the thoughts were fleeting and disjointed, and she realized she hadn’t really given in, she’d made the decision herself. “Rory,” he’d been the one to give her that choice, and she grinned at him again before kissing him, inclining her head to press her lips to the underside of his jaw as she rocked forwards again, doing her best to keep, or even start, some semblance of a pace.
