Desire to pleas (R-18)

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. Curious, he deliberately rubbed those areas, feeling her body respond even more strongly.

'Is this how women cum?' Cassian wondered, intrigued by the idea of making Katherine reach her peak through this method. Now that his own desires had been momentarily satisfied, his mind was clearer, and he wanted to give back, even if she was asleep and unaware of his efforts.
