Alec could hear the desperation in her voice, the need, and he was more than certain if he tried to speak right then she would find his tone a perfect match. Hands moved down to her hips almost instantly, fingers digging in, not caring if it caused her any sensation of pain at the moment. What he wanted was her and he was willing to do anything in order to have her.
When her hips moved up, nothing was going to stop Alec from meeting her, and a rough thrust had his entire length barely inside of her. Hands released her hips and grabbed the bed instead, needing something to hold on to, anything that would give him leverage. No time was given to Navi to adjust to the sensation, he was already slamming his hips forward again.
