To be honest, Dominic hadn't heard much about her previous relationships. Probably because he had never bothered to care before. He didn't think she was insufferable or too serious. Probably because he was becoming rather accustomed to knowing this specific side of her.
As for her laughter, it was infectious to him. He managed to let out a laugh as well before smiling softly. He really didn't notice the difference in her tone or her laughter, actually he thought it was fantastic. The sound to him was wonderful and he wanted to hear it more often. He would be sure to remember that.
He was terribly happy when they kissed again, and made sure this time to put more behind it. He let some of his pent up lust and passion leak out, pulling her closer to his body. He liked the feeling of her soft body and Curves pressed aganst him. He wasn't ashamed to say it turned him on to no end. He shivered where her fingers were tracing circles on his back and he made sure to wrap up her soft hair in his hands again. This was so fantastic. But the thought still lingered in the back of his head that he shouldn't be doing this. She was too good for him and he would ruin her.
