Tethys -- Growing the Tribe
Part 2
This is the second part of the second of a series of tales of and by Tethys, a friend of mine.
Most of the characters are introduced in the first series, "Gesso".
Sorry for the long delay between stories.
There are definitely more coming.
Hope you enjoy!

I've made this trip dozens of times. I know how long it takes, I know how it feels, I know the bumps and textures and turns of the route, and I know just what to do to keep this precious cargo bottled up inside me. It's only a couple of tablespoons, but it's thin and slippery, and gravity is pooling it just above the narrow, muscular section of my tunnel. What sperm was mixed in with the semen is slowly swimming the other direction, still energized in its futile quest to fertilize the egg that will never arrive. I concentrate on keeping the muscles tightly closed, not letting the roughness of the road open me up for even a second. I don't want to lose it, yet.
There are those who believe that Carl's fascination with sloppy seconds, his desire to feel another man's cum coating his cock as he forces it out, stroke by stroke, is a symptom of repressed homosexuality, or maybe some weak acknowledgment of submission, the acceptance of cuckoldry, the humiliation of being the afterthought. But Carl doesn't see it that way, and neither do I. As Carl sees it, it's an act of dominance, of taking something from another man and making it his own, displacing the competing seed and overwhelming it with his own. It's an act of power, of triumph, but it's not one that can be delayed.
I've spent some time musing on it, especially during these trips between two lovers. It's about twenty minutes of thinking each time, and I've even done some research online. I've arrived at an explanation which satisfies me, and meshes perfectly with my own vision of my place in the cosmic order. It's the most primal but fully human expression of our evolutionary development, a behavior that precisely matches our anatomy. It's sperm competition, promiscuous mating, ambiguous fatherhood, and the foundation of tribal loyalty.
Our closest primate relatives, I reason, are chimpanzees, bonobos, and gorillas. They each have some nearly-human traits, but each have very different reproductive styles. Gorillas live in harems, in which a single silverback protects and watches over a group of females and their young. The odds are high that he is the father of the great majority of the offspring. He doesn't worry much about competition. Consequently, gorilla sex is nothing to write home about. The male gorilla has the smallest testicles of all the great apes, the penis is small, and sperm volume is low. Mating is perfunctory, and not done with much urgency. The noncompetitive environment makes for a benevolent and tolerant male, and the youngsters are safe, unless the silverback dies and the harem is invaded by a stranger, outsider male with no possible relationship to the offspring. Then there's a real danger of infanticide.
Chimpanzees, on the other hand, have a no holds barred approach to sex. A receptive female might mate with dozens of males in a single day, as often as 50 times. Chimpanzees fight about a lot of things -- territory, food, power -- but not access to females. Everyone gets a shot. There's no individual competition between males, but sperm competition is fierce. Chimpanzees have the largest testicles and the greatest sperm density of all the primates, and a penis twice as long as that of a gorilla. For all that anything goes behavior, though, it goes fast. Sex in chimpanzees only lasts about ten seconds, then it's off to the next partner. Any individual male chimp is unlikely to be the father of any particular infant, and infanticide is an occasional result.
We humans do it very differently. Women don't advertise their ovulation, yet we're always receptive, so a man can never be certain whether sex will result in pregnancy or not. Human males produce copious amount of semen, but the sperm density is low, another reduction in the chances of conception. For a man to have good odds of impregnating a woman, he's going to have to fuck her frequently. And if she's been fucking another man? He needs to remove the other guy's cum from her pussy and replace it with his own. The human penis is great for that kind of task. It's big and fat, and fills up the vaginal space, squeezing out other fluids. The head of the glans makes a nice reverse scoop, catching any semen in the canal and drawing it out with the withdrawal stroke. And if the guy knows what he's doing, he can take his time, thrusting repeatedly until the vaginal tunnel is thoroughly swiped before depositing his own load inside. Just the kind of motions that make a woman want to come back for more, that make a man a fantastic cocksman and lover, are those that also tend to most efficiently remove the sperm from potential rivals. It's sperm competition, but but a type unique to humans.
