"Splutter...gulp, gulp..."
Perhaps hearing the praise from her master, the number one beauty subconsciously felt excited and honored, as she made an effort to swallow the almost endless semen in her mouth, while actively using her tongue to lick the fully erect penis.
From the foreskin to the tip, blocking the ejaculatory opening, the mischievously smiling beauty then changed tactics, thoroughly licking even the coronal sulcus with enthusiasm.
As she had to ensure her master could ejaculate comfortably without obstruction, she had to be attentive to swallowing the semen and constantly use her mouth to provide more stimulation during ejaculation.
The kneeling beauty, having almost exhausted all her knowledge of oral sex, kept her nerves taut without a moment of relaxation, fully focused on everything above the neck, while continuously making the sound of swallowing semen.
