Her eyes were already closed as they kissed, but once she felt him bury himself inside of her entirely, they squeezed shut as she took a sharp inhale through her nose. There was indeed pain, a sort of ache that she'd never experienced before, and just from her reaction alone, he had to know this was her first time. A part of her cringed at what his own reaction would be, if he would be angry that she'd lied or if he would take extra care to cause her more pain as he continued, but neither happened. He didn't stop, didn't lash out, didn't even give her any kind of look. He kept going, pulling out and then re-entering her body as he moved his mouth down to her throat once more.
Her head tipped back to give him enough room to work at her throat, her pulse thrumming wildly beneath his lips. Every movement he made inside of her pulled a strong whimper from her, as well as caused her to slide her hands down his back again and leave long red lines with her nails.
