'He is enjoying...it...' Katherine observed Cassian's expression as he breathed heavily, his satisfaction evident. She followed his instructions carefully, creating suction with her lips as she moved them along his length, her actions slow and deliberate, occasionally making a soft sound as she worked. She added her own touch, moistening him with her saliva.
Cassian couldn't help but appreciate the improvement. At first, her efforts had been clumsy, but now, she was far more skilled. He let out a quiet praise, his voice full of approval, "You're a fast learner, my lady."
Katherine didn't particularly enjoy his praise. She hadn't intended to be good at this sort of thing, but seeing that he was clearly enjoying himself, she found herself willing to improve, even if she didn't fully understand why. In some way, she even found satisfaction in pleasuring him.
