Sean makes a noise that falls somewhere between relieved and ridiculously turned on, messily kissing her again as he shifts just enough to get a bit more leverage. He doesn't hesitate any longer, all his ability to take this slow having evaporated the instant those words were out of her mouth, and he's guiding himself into her from behind before the thought that he's doing it even really registers with him. When it feels this good, they should be allowed one little lapse in judgment.
