Naia had gotten used to the taste throughout all the times of trying oral sex, but she couldn't drink it down. His glans could slide deeply past her tonsils without any issue, a sexual skill she had discovered with research, but the thick sticky substance itself made her gag uncontrollably if it climbed down her esophagus at all.
After that discovery, there were times where she had to pull back as it exploded because he was still too deep… and the rest of his semen would cover her lips and chin as she violently coughed because of what went down. She wasn't a fan of that, so they worked out the signal.
It was very thick and accurate this time, spraying entirely onto where she angled it. Another sign of her long practice with the man. She let it pour back out of her mouth onto his shaft as she caught her breath. Now that she had seen it, the feeling of its heat spraying deep into someplace else was the only thing her body craved.
