Obsidian gagged again as he thrust his hips more rapidly, and she was trying to keep up. She tried to shake her head, as her moans of reluctant pleasure came more and more frequently, escalating in volume. She was tempted to bite down, and severe his cock, but she knew that with her weakened condition it would not be wise. As he whispered that in her ear, goosebumps rose along her arms and legs, and chills rolled down her spine. She tried to pull away from him, but the collar held her firmly in place.<br/><br/>Obsidian knew it wouldn't be a good idea to try to fight him, in her condition she would be badly beaten. So instead she swirled her tongue around more rapidly as she sucked harder and faster, moving with his rhythm. She shuddered and gagged every now and then. Suddenly she felt his cock getting bigging as if he was about to cum, and it blocked off her airways, her eyes widen and she tried to pull away from him desperately.<br/><br/>Her wings snapped open again, but were extremely heavy as a side effect, but she pushed them forward, her forehead beading with sweat from the effort of moving them. As she pushed them forward, it made the chair scoot back an inch and his cock slide a bit back allowing her to breathe again. She gasped for breath, as her wings fell back and folded in. Her shoulders felt like their were on fire from the effort of that, but she needed to breathe. She shivered, tugging at the restraints as she caught her breath.
