Susan's body was responding to far too much sensation as he seemed to have found that spot over, and over again. She knew that feeling now - having just experienced it before, but she was close to another orgasm.
But this time it was different. It wasn't his tongue, but his cock and the way it brushed up against her with each relentless thrust. So lost to the feeling of him filling her, that she didn't expect her orgasm when it came, and she cried out in surprise, his cock filling her as she trembled with pleasure again through it all. A string of cries escaped her lips, his name lost somewhere in the words.
