Krynienne's eyes flashed when she met Zeph's gaze. Her serpentine pupils were visible for less than two seconds, and Zeph could not be sure if it was a reflexive response or something she did deliberately, as there was no way she should be getting hungry enough for it to be a warning.
Because how could she be hungry when his cock was still between her lips and poised to give her another helping of her liquid lunch.
Granted she had to wait for his return to have her lunch making it later than usual, but that would have just made her more eager to enjoy her meal.
Feeling the increase in suction on his tip as she closed her eyes and moved her hands up along his spine as far as she could reach, Zeph was inclined to believe that she had flashed her eyes at him to tell him that she had eaten her fill, but was still horny and wanted to keep going and pleasure him as he sat there in his Captain's chair.
