Although he had told her to use him, and she really was going for it, he didn't feel used in the slightest. He felt amazing, he was on an absolute high. She might have been very much in control of the situation, but it felt incredible to have her want him so badly, to be pressing herself against him so hard he could hardly breathe.
He desperately wanted to please, and her movements and demanding words just spurred him on, repeating motions that seemed to get the biggest reactions over and over, drinking her in, letting himself get absolutely lost in the moment as she overwhelmed his senses. He could feel it right down the rest of his body, he was aching for her. Not just for a release, but for her. She was the only one who could do this to him, she was the only one who was allowed. They both had history, but she was only one who would ever have him again. His mouth belonged to her.
He gasped and moaned against her as he ate her, his fingers gripping at her hips even though they didn't restrict her movements in any way - she was absolutely riding him. And he loved it, he wanted to please her, and God he was trying.
