Earlier, Cassian had been so eager to reach his orgasm that he hadn't paid much attention to the finer details. But now, as he slowly pushed his finger in and out of Katherine's anus, he noticed the subtle reactions—how her muscles would tighten and tense whenever he touched certain sensitive spots.
