Hermione didn't mind that he needed to breathe, as silly as that might sound. She wanted to kiss him and never let go, but she needed to breathe as well so it worked out just being as close as possible. She did her best to keep her lips on his, or her forehead against his and she wasn't bashful about pushing his hair out of the way so that she could see his face. The closeness was the most important part in all of this and that included being able to see him. She didn't try to sensor the expressions of pure joy and wonder on her face and she was so thrilled to see him lose some control.
"Oh Merlin, Severus," she moaned, shifting her hips out of pure instinct. It shifted him to a different angle and she gasped, arching her back to press closer against him. He needed to only thrust a handful of times more before her entire body tensed, holding back the impending orgasm. "Come with me," she begged breathlessly. "Please." Her eyes were locked on his, and she knew she wouldn't last more than a few more seconds.
