Khoth's "Junk" & Other Sensual Matters...

Penis: long, not too fat, in fact, rather elegant; conical, slightly pointy head; all blue, darkening towards purple when aroused (similar to his nipples); uncut, darker blue foreskin.
Testicles: egg-shaped, slightly elongated, blue-purple, smooth, relatively hairless.
Pubes: moderately dark blond, fine in texture relative to humans, but coarser than hair on his head.
Preferences: prefers to top, but somewhat versatile; likes extended foreplay, kissing, sucking, all-over body contact; responsive: sensitive nipples, ears, neck; knows how to ask for what he wants, but otherwise not too vocal; rather romantic in private, to offset his military bearing in public; an attentive lover.
Overall: rather elven.

Oh wow. Alien penis. Hmm. First, I think that Koth would totally investigate human anatomy and sexual function. He cares about Jace so much and would never want to be ignorant and hurt him. I think he would be so prepared.

That being said, I’m going to have to say that Koth’s penis is longer than the average human. Thinner at the tip, maybe a more flared underside of the head but has girth at the base. I like the idea of a knot but maybe not a knot per se, just much thicker than a human. Maybe he’s scared of putting it all the way in for fear of making Jace hurt but Jace, ya know he’s altered, so the Osiris let’s Koth or Jace know that he won’t hurt Jace as Jace begs for it all, hehehe.

I think the Thafell are all about consent. I mean, that’s the upstanding thing to do in terms of xi and xa. So I think whatever ritual that surrounds coupling, especially first coupling, has to do with spelling it all out. Which probably elicit an extra turned on Jace from all the ‘dirty talk’ he gets to hear as he says, “yes! Yes to all that!”

What about two instead of one? Like two penises that hook on/around each other and on orgasm one releases seed and the other attaches to the partners most pleasurable point. Jace could become delirious from the pleasure overload.

Also what is Jace is the 'top' and Khoth 'bottoms'? Khoth could have a special mating opening to receive his partner and his passage could ripple rapidly during orgasm to ensure mutual pleasure.

What about mating rituals? Like Khoth needs to eat a special blossom or something to properly bond with Jace...

From the book so far, it seems like the Tha'fel aren't that super different from humans, aside from size and coloring, but maybe something like a short series of a few 'ribs' or nodules just below the head that expand a bit when they're with their partner/mate/one and climax (just enough to be noticeable but not painful, like pressing up against the prostate and feeling good kind of thing).

I would think that for technique/ritual, they would be a combination of methodical and thourgh, and passionate and intense, especially when they feel really connected with their partner, a sort of 'you're special, this is special' kind of pulling back of their usual Uber control?

Also, sorry if I got too detailed in the first part.

Since beads are so important to their culture, I think it would be interesting to have his junk have a texture to it, like beads under the skin. The texture could become more prominent the more excited he is.
There could be some type of release for the texture beads, so male Thaf'ell do not get to experience them until they mate with their life mate. Like a ring at the base that is taken off by their life mate. Or a third ball drop that happens to fully matured Thaf'ell, that ball controls the beads, and once the drop happens they can't do the deed unless it is with their mate, seems like something the super self control Thaf'ell would do.
I saw some people were interested in a knotting type situation, maybe the texture beads could become so prominent when he is inserted that it has to calm down before he can remove it. I think, and hope, Thaf'ell would be incredibly intimate with their mates. Being locked together would definitely do that.
Also I don't the shape shouldn't be to human like, maybe the head can be pointy-ish, not so rounded, that would also help ease the entrance.

I think, since Jace has never experienced the joys of sex, Koth would want to give him the whole experience so they would both be switches rather than one is mostly the bottom or top. But considering Koth's past abuse he would be hesitant to let Jace top him. So maybe they, like others have suggested, reach a psychic link during orgasm and thats when Koth feels safe and reassured enough, having experience all Jace's feelings towards him, to let Jace top him next time.
Also since they will never truely have privacy, maybe Jace can discover a way to metally lock Ghenna and the Osiris out of his head because I just imagine the Osiris constantly trying to inject with "helpful information" whilst Jace and Koth are trying to be intimate, ruining the mood completely.

Lets see.... With my "Alien" race, they have to find their true mate (for lack of a better term). They only have one and if they don't find them, they die a painful yet vanish-y type death (think Thanos in Infinity war). Now, as far as junk and "rituals" go... I have the following ideas.

* Khoth's junk can enlarge when he is in Rut (for lack of a better word)
* I think it would be awesome, that once Khoth finds his true mate, that they gain abilities. Like telepathy, or even telekinesis!
* Maybe Khoth's junk has a bacula (penis bone), which I think would increase the pleasure
* They gain a unique tattoo, which not only identifies that they are true mates but maybe can increase sexual pleasure when Khoth or Jace touch it

Curious about what would happen if it was prehensile. Able to be consciously controlled and manoeuvred as if it was any other limb. No need to hold and "line up". Able to feel for the prostate and bend to aim at it much like a finger could.
As for practices.. they are all about logic. Its not logical to partake in sex except for certain reasons main ones being while trying to conceive or while in "training" . You have already established he's had a bad teacher/student relationship. Maybe humans sexual practices will be so liberal and freeing his mind will be blown.
What if outside of teaching relationships married/mated pairs such as khoths parents are ONLY married because they produced a offspring. It would be logical to live together to care for and raise the young produced from procreation. If no pregnancy had occurred they would have moved to a new partner and tried again etc etc untill the couple conceived.
Gay is not a lifestyle choice for civilians. Its accepted in the military as the norm as it would be illogical for there female active military personnel to be pregnant and the couple to wed and raise children on the spaceships so its accepted that active military would pair up (same sex only pairs allowed) for stress/hormone relief.
Also note that the military lifestyle doesn't seem to be a career choice so much as a choice made for you buy some other government entities based on you natural abilities (maybe part is a psych exam which determines if they could naturally perform their duties in conceiving and concluded any queer members be assigned military for their sake, the breeding programs/cultural marriage ideas sake or some other reason). Not every military needs to be queer, as they can take leave to take part in the process of conception and quit if it takes and/or change jobs or have a set 15yr service etc... But all Queer characters are military.

By the way, while we are giving Khoth a lots of characteristics that Jace should love, I think there are some human characteristics that Khoth will love about Jace's junk.
Like, since there seems to be a wide agreement that Khoth's cock should be ribbed/have some texture, I'm sure Khoth will be amazed at the smoothness of Jace's cock. It will be so soft and nice in his hand in contrast to his own!

Khoth could also fall in love with some human rituals or behavior. Like I could see Khoth learn that humans share rings when they get married, and then secretly hope that Jace gives him a ring

If the Thaf'ell are a superior race then I would think that the male specimens must have a protection for that vulnerable area (you know a punch there is a K.O.) maybe the organ "extrudes" from the body when it's in use? protected by the bones when it's not mating time.
Some hermaphrodite traits could be interesting too. Maybe they have the 2 sets of organs to give and receive. Altought only one works for reproductive matters and the other is simply "enabled" to please your partner if your conection to the other person is a deep one?.
For mating rituals I would think that is post-act because it's such a passionate event... Maybe a kind of croon to soothe and lead your partner to sleep? Or maybe, if they are not in a lust fog, they can do something to simbolize utterly trust and affection like put the palm of their hands on their partners chest (or wherever is the heart) and this gesture is different according to the kind of pairing. I remember that there are partneships made to teach so it would be different in this instace, like put foreheads together as a sign of an "educative act" and whisper some words.

Ok, so truth be told, I’ve gotten behind on all my reading and haven’t been able to keep up with EoS. That is something I’m going to rectify very soon though! That said, I’m not sure how far Jace and Khoth’s relationship has progressed (i.e. confessions, kissing, groping, etc.) so I apologize if I touch on something that’s already been broached.

Ritual:
I like the idea of true/fated mates, so I feel like Khoth realizes that Jace is his true mate. After that realization there be some ritual that is done to signify the importance of a true mate paring. The one thing that comes to mind are Khoth’s beads. Since Thaf’ell beads are an integral part of the species and their familial status, there should be some sort of ritual of “the giving of beads” to their one true mate. It doesn’t necessarily have to be more than one bead, but something where Khoth takes one (or some of his beads) and threads it/them into Jace’s hair himself. Kinda like penguins giving their mate a pebble. Since Jace doesn’t have any beads of his own, maybe he could give Khoth a wedding ring OR Jace could start to acquire his own set of beads and it’ll be an exchange of beads ritual. It could be considered like a special true mate Thaf’ell marriage ritual or a “soul-binding” ritual.

Sex/junk:
I don’t think Khoth’s junk should be something too crazy or wild. It should be something that would make it possible for Jace to accept without the need of some super intricate and additional preparation. I’d hate for them to not be able to have quickies every now and then. I feel like extra necessary preparation would ruin those fun trysts.

I do like the knotting idea. But perhaps the knot only occurs with the Thaf’ells true mate.
Khoth is bigger in size, so I feel his dick would be proportionate and be larger as well.
His shaft should be the same color as his skin with the head being a slightly darker shade of blue. Both turning darker when engorged.
His precum could be a lubricating aphrodisiac that heightens/enhances arousal whether consumed orally or inserted anally.
I also think it would be neat if, along with some sort of additional texture(s), his dick had some sort of markings/tattoos on it. Maybe something that only appears when highly aroused. Or perhaps the markings could play into the whole true mate recognition idea.

And that’s all I got...for now.

Wow! So many comments already! I'm a biologist and let me tell you, if you've thought of it, nature has already done it.

Super crazy penis examples probably wouldn't fit the story, but they are a lot of fun to bring up at parties.

I agree that the courtship itself would probably present lots of opportunities for miscommunication, angsty or hilarious. I also really like the idea of texture, but imagine it being artificial. Maybe there are culture specific tattoos or piercings. Especially if it was something only seen with an intimate partner.

There are lots of knot suggestions, but what about feline spines? I think interspecies sex would probably need some figuring out. Spines would be painful for a human, so they would have to figure out a solution? Extra thick lube? condoms? Maybe Khoth has to pull out before climax?

Humans are sort of unique in having exposed penises, so I definitely vote prepupal sheath or eversion. Internal testes?

I feel like knotting would be too much. It’s so unique to werewolf stories, and when you hear about the term “knotting”, most ppl would think of a werewolf.
So I think it would maybe take away from other factors being put in place regarding his junk.

Okay. I know I’m responding kinda late. Sorry. Anyway, I was thinking maybe instead of a shape difference, Khoth’s semen could have an aphrodisiac quality. Of course, maybe such a reaction to the aphrodisiac would only be wonderful but mild between two Thaf’ell, but since Jace is human (sort of) and humans haven’t been exposed to this kind of thing, he might have a more intense reaction. Maybe when Khoth cums inside Jace, Jace would kinda go deliriously wild. Hee hee.

I say we stick with the tried and true cock and balls (which has already been implied in early chapters), though Thaf’ell are larger overall so, large duh. They are implied to be a mostly hairless species unlike humans, so if he has pubic hair it’s minimal. Perhaps a small and short cropped tiny thatch. Foreskin is an evolutionary trait that protects the groin so I believe a humanoid species like them would also likely have them. Insofar as mating practices are concerned, a form of socially acceptable pederasty is implied in early ages, while permanent mating is done thereafter. I also think that with their obsession of Xi and Xa they would mate face to face. Since sex is intimate they would lean against their non logical/emotional nature there. So far the Thafell have proven to be remarkably similar to humans (mentally and physically) so nothing too radical when it comes to Khoths junk lol. If you wanna give it something extra then the earlier suggestion of “ribbed for his pleasure,” would be perfectly acceptable!

It would be super sexy if he had a knot but due to cultural demands was forced not to use it. Before their species had advanced knotting was a regular thing in sexual relations but now is considered too animalistic.

We know Jace would love it. And the commander loves to please his Pilot

I am a bit behind on answering this one, just found it in my spam folder. You know having double the pleasure couldn't be all bad, when one is done the other comes out to play. Now you mentioned in the story a while back that when Tha'fell mate they connect their souls and are able to hear each others thought, like a mind meld of sorts. Khoth and Jace are not doing anything typical thus far in their relationship so far, so why should their mating be typical human or Tha'fell? Perhaps Khoth will just fall into their mating with some sweet gesture from Jace and let nature and fate take its course.
