With his face pressed against the soft cheeks of Katherine's butt, Cassian felt like he was in heaven. His tongue explored her intimately, tasting the heavenly sweetness of her body, completely forgetting that he was supposed to be massaging her, not indulging in this.
But how could he stop when there was no rejection from Katherine? Even though she was awake, she let him continue, silently enjoying the pleasure he was giving her.
Cassian took full advantage, his tongue teasing the rim of her anus before slipping inside, slowly lubing and relaxing the tight muscle. At first, it clenched around him from the sensation, squeezing his tongue tightly, but over time, it began to loosen, allowing him to explore deeper, making it gape slightly with each gentle movement.
