Selturman knew that he could not relieve himself of this for long; it would take 10 or 20 releases to get it back down to its normal levels. That night, Selturma slept with Rex, to give him maximum exposure to her pheromones.
The next morning, Rex was very aggressive, and feeling very full, as if he had to release himself by a means other than squirting his seed; he was so full of it that if he didn't release it soon, some of it would come out by itself.
He could not even get his pants to fit on, so he had to go clad only in his loincloth.
