The male wlko is now sexually fully developed, and upon being sodomized for the first time ("opened") is fully capable of erection, intromission, ejaculation, and fatherhood. However, wlkon of such an age perform procreative functions only very rarely indeed. Rather, for three to six years their sexual activity–which in healthy boys is practically continuous–consists of sodomizing one another. During this period they attain full growth; the mane lengthens, thickens, and darkens, as does the neck-stripe; the testicles increase in size; and there is a marked increase in the length and thickness of the neck. To the untrained eye, ten-year-old wlkon look like large, mature, and even impressively male animals–unmistakably so during the sexual act itself. But a wlko of 13 or 14 years is almost a different species: tall, rangy, well-knit, and masculine in a way that shows up their ten-year-old selves for the boys they were.

Sec.5.2 Females. Female puberty is less apparent physically. There is nothing like the breast or vulva development of certain species, or other types of dimorphic specialization (such as the shedding of the tail at puberty of the females of the felids of 3-Tau-Ceti, or the darkening of the vibrissae as among the Red Wolf morphs of this planet). However, there are some outward signs, which appear a year or two later than in the male children. The lesser is a change in the appearance of the throat-lines; while these were present from the age of perhaps two months, at puberty they become notably more pronounced. The major change is in the eye color, which passes from the pale blue of youth–a beautiful color itself, as has been commented on in the literature–to a striking deep green of sparkling chatoyance. (Perhaps half of the field reports on the wlko available to me inject personal remarks to the effect that they know few creatures more beautiful than adult female wlkwim. An opinion of this nature is out of place in a morphologue, which is not to say it can be quarreled with. I might add that the adult females have a natural grace which is fully equal to their physical charm.) As in the males, the "horsy" elongation of the female neck occurs during the eighteen months or so following sexual maturation as signaled by the change in eye-color. It is however less pronounced, and the neck is significantly less thick and more graceful.

Sec.5.3 Opening: an Important Social/Physiological Rite of Passage.

"Opening" adolescent sons, that is, penetrating them anally for the first time. This is a parental duty. Early field workers naturally assumed it was a form of incestuous homosexuality, that the older males derived special pleasure from coupling with adolescent males, or perhaps to reinforce social dominance, and even referred to observed phenomena as "sexual abuse of juveniles".

Sec.5.4 Sexual responsiveness: a comparison.

A chance remark by a wlko co-mate in a family group I was studying prompted further, casual, investigations on my part, leading to findings unlike any hitherto reported in the literature familiar to me.

Wlko are friendly creatures but somewhat bland of personality; "Jasper", a young co-mate, differed from the norm in being notably bluff and hearty. One conversation with him, to my surprise, turned into a case of the investigator investigated, when he started to ask me questions about the sexual requirements of my species. He was understandably perplexed by my explantion (in substance, that most males coupled exclusively with females, though a substantial minority of both sexes preferred a form of sexual contact similar to linking). He undertook to commiserate with me for what he misunderstood as some kind of ascetic self-denial, since, as he put it in so many words, the experiences were completely unalike.

This naturally led me to inquire further.

He explained, in substance, that the first penetration of a male’s anus was a "beautiful" experience, "when you can feel his tail with your purse [scrotum]", i.e., when fully-inserted. Every "pull", he continued [in Wlko, "pull" refers to the insertion of the penis], was "beautiful", but your mane really stood up when his "[third] hand" gripped your black. Then the "beauty" came in intense rushes, "pull by pull", and (he said) his testicles would swell to the bursting point before they "snapped". Then it was all over. At a wlkatar, he added, he’d withdraw right away, but when linking to "Ryan", his co-mate, he was too exhausted to do more than just lie there for a while, "and let my black slip" (allow his penis to withdraw into its sheath).

As for vaginal copulation, that was totally different. The only similarity, he suggested, was (in effect) psychological–the "comfort", as he put it, of sensing the "beauty" that was kindled by the sensation of his "peg" as it slid into a "snatch" or a "socket", respectively (these terms translate Wlko words for the organs that are of the utmost vulgarity for "penis, vagina, anus/rectum"). He explained that you could tell, and easily, and it was a "beautiful" feeling, though nothing like the "beauty" that "fills your whole body" a moment later. And even that was different, since the "beauty" his intromission provided the female came only as he "filled up her snatch", whereas he could sense a male wlko’s response from the first probe. Also, he added, while it "felt beautiful" to "pull" a wlkwy–by which I gathered he meant to insert his penis fully–it wasn’t nearly as definite a sensation as "pulling" a male. This accords with the anatomy of the innervation of the penis (Sec.4.2.9, above).

There was no "rushing" of "beauty" through his body when he copulated with a female, Jasper said. Rather, at first there was mostly the satisfaction (which he indicated was very satisfying indeed) of sensing the "beauty" in the female’s body. Then, as copulation proceeds, and after the female purrs loudly (i.e., experiences orgasm), he feels a slow but steady increase in "beauty" in his whole body. Surprisingly, "Jasper" characterized the experience as being similar to being sodomized, which apparently also involves a gradual increase in erotic pleasure ("beauty"), especially after you feel the male’s penis "getting big inside you" [a common way of characterizing the "third hand" effect, from the point of view of the male being penetrated], when each "pull" [thrust] adds to the erotic sensation. In both cases, said "Jasper", the feeling of "beauty" became almost unendurable, but with different dénouements: "Every time my nuts snap into a cunt", said the young man, "I think I’ve died. I really do. It’s so draining. I just about faint from the beauty. Nothing like that when Jason ["Jasper’s" co-mate] snaps into my gut. Then it’s mainly a relief. I love it. It’s so intense you can’t hardly stand it, can’t catch your breath, and then he snaps and you’re so relieved by the wonderful soothing feeling that comes then" [a reference to the phenomenon elsewhere translated here as the "bliss" following sodomy].

I asked him if he felt anything like the vaginal orgasm (for that is what it plainly was) when being sodomized, and he pondered the question. No, he said, in substance; sometimes his own eggs "spilled", but that was never as beautiful as "my nuts snapping into an ass or a cunt". But he was emphatic that being sodomized was a "beautiful" experience, from the first penetration (which, he indicated, was a unique sensation: "taking black, well, it fills my whole body with bliss"–remarkably enough, he used the same word normally used for the post-ejaculatory euphoria universally reported by sodomized males).

On the basis of this account I subsequently asked other wlkon to compare the experience of male/male vs male/female copulation. The men didn’t always feel like talking about the matter at all, but when they did, their accounts generally corroborated "Jasper’s". The subjective facts as described fit well with the details of the innervation of the wlko penis and its interaction with the anatomical features of the vagina and the male anus/rectum.
