true understanding of how to make love to a woman. They went about it in the most brutal imaginable way. Firmness, yes—that was necessary. You had to be very strong and sure of yourself. The slightest doubt or hesitation could be fatal. In fact, you could develop what human psychologists called a complex in regard to one particular woman if you failed at the wrong moment, no matter how accomplished you were with other women. He had been on Earth long enough to understand these things, to realize that Martians were no different from human males in that respect. One failure, and a woman could be lost to you forever. And she might be the most desirable woman you'd ever known, and couldn't do without.

The warrior-caste brutes were taking unwarranted liberties with two of the captive women when they were under strict orders to do no more than clasp them firmly and carry them into the ship. It did not anger him too much, because the women the brutes had captured would probably soon become their mates. But what if it gave the warrior who was carrying the slender woman ideas?
