Okay I caved and wanna share the stuff about my space au that probably doesn’t need to be explained but I wanna do it anyway

Too much thought has gone into this o wanna talk about it. I’d prefer if this wasn’t rt’d but it’s not a big deal if so

How aliens bang I guess

Lets start with Jirou/bkg’s species which is currently unnamed (dw it’ll have specifics one day)

Basic anatomy is first things first !!!
I’ll add my shitty phone doodles on top of actual art because it’s cute LMAO just pretend they’re Deku’s notes or some shit

- Overview on anatomy and sexual dimorphism-

An exoskeleton like outerlayer cover’s this species body.

YES they do have bones under their real skin, but they’re fragile and only meant to support the body when in molt or intense physical activities.

Their ‘skin’ isn’t soft but it’s not entirely hard either. Slightly pliable and honestly, it feels like .... soft leather in a sense

This species is very very flexible ! Their bones CAN break, which acts more like fiberglass in a sense it splinters instead of snaps. Super rare

The feathers are for attraction (like birds of paradise and their funky feathers) and for feeling. Kind of like a cat’s whiskers!! The feathers do not fall out all at once, but one by one. They still have them during molt.

Skin is usually any color but mostly secondary colors.

Blood is BLUE!!! They bleed blue, their tongue is blue, their genitals are blue, etc. blue blue blue. The darker patches of their skin is very soft and fragile, the exo isn’t as thick here.

Any other fluid? Tears, spit, and semen/discharge is a light yellow.

They have exoskeletons. SO THEY MOLT. but instead of molting like a bug, they shed their molts piece by piece. So let’s say, the forearm splits off, then the leg. They’re very sensitive and vulnerable when molted and waiting for their exoskeleton to harden.
Molt every 4 months

Females stay soft when mothering a child. They’re soft for about 4/5 months, and are extremely reclusive and defensive as they’re easily harmed. Their baby feeds off of their breast, where the thinned layers of skin are able to be suckled on! Babies actually don’t eat too often

Lets get into spicier details now, shall we?

In molt? EXTREMELY SENSITIVE!
not only that, but genetalia is extra exposed in this form, there’s no exoskeleton protecting much. This is when a lot of the species mate because they’re so sensitive and fertilization is much easier

Feathers basically turn into clits LOL. Like on both species. If you touch that shit, they’re gonna squirm and moan. WHEN hardened, they’re still very sensitive, but even more so when the flesh is tender around the feathers

Molted skin has a sheen to it and mostly just feels like.... a really sweaty person. Not exactly sticky nor dripping, just moist

Very pliable, they’re basically jello like this, kinda cute.

They don’t really have ‘heats’ when molting!! It’s just a social thing!!

Like “oh we’re already sensitive and exposed, might as well fuck”

Females don’t carry for long, nor do the kids stay young and helpless for long either. Expect a female to carry for at least 5 months

TW // PEEPEE TIME!!!
Lets get into some gentalia !! I’m kinda shy about this stuff so I’m sorry if I am vague
I’m also really new to drawing dicks so this is kind of... uhh
I don’t do the dicks justice, use your imagination for the fun parts

- Males -
The shaft is soft and slimy, almost tentacle like but it holds form. It is flexible, but much like humans, once hard, it’s not that pliable.

Blue blue blue !!!

When sheathed, the little ‘claspers’ (not sure what to call them lol) stick out and hug the body.

The ‘claspers’ are little extra bits of flesh that stick out but have tons of uses !!

When not mating, the claspers kinda... chill out and exist. They hug the body when cold and lower when hot, but they don’t hold anything like semen.

They can also be used for feel around

They almost act as whiskers for the dick. Not particularly sensitive, can’t move too much by themselves. Doesn’t mean you can’t toy with them though ;)

The claspers secrete slick for the females. Small pores all along them pump out the runny fluid, which is also a pale yellow

Cum is very sticky, and there’s a bit of it each load. Also pale yellow. But, the slick from the claspers beats it by a long shot, as there’s much more of that than semen.

The males are the ones to get ‘wet’ with the species, actually, rather than the females.

Males CAN fit their claspers into a partner along side the dick. While they can’t pump out stripes of semen like the penis itself, it can still get quite sloppy.

Wanna know something fun???
Males orgasm WAYY more than the females do!

Male‘s bits are way more sensitive and often can produce more than one load. Therefore, males can get very messy... (sorry bout future messes kiri)

Not only that, but impregnating a female isn’t easy, so more than one load is super helpful in the long run

Males get super fuckin’ sensitive in molt so it’s more likely they’ll cum even more during it. Like, on average? You can milk out 4-5 orgasms in one session from a male. Now imagine molt sexies

Also, in case you’re wondering bc I have mentioned this whatsoever until now

Both genders have an anus so,,, yeah. Just thought that was an important detail bc I forgot about it up until now.

You can’t really put anything in male’s slits once the dick is out, there’s no use in trying to cram your fingers in there.

Onto the females !!
I haven’t drawn an awful lot on the females just yet, I hope to soon!! So here’s what I can offer for the time being

While I like to call the male genitals the ‘flower dick’ because of the cute little claspers
It’s only appropriate to call the female’s bits ‘butterflies’ lmao

So! With females, the labia actually opens up when aroused, otherwise it stays closed like in the dumb doodle

Female genitals are similar to humans but the labias close up. It’s very similar to a Venus fly trap in appearance, but still soft and fleshy. The clit is actually on the bottom half of the slit, this allows males to rub their claspers against it.

The folds are moveable but nothing crazy, females can only control opening and closing to an extent, buuuut can use it to clamp down on a males dick, so that’s cool!

Theyre quite dry, females to secrete slick, but not nearly enough to count as lube for penetrative sex

Females having sex together will often intertwine their labia for grip and rub the clits together. It’s... kinda cute tbh

Females don’t orgasm too often, maybe once or twice! This increases when molted of course.

They’re pretty fun to edge, at least—

The ‘breasts’ females bare aren’t too sensitive, only where the skin is thin. Only pliable in molt tbh

The thin skin heals rather quickly! When females have offspring, a substance similar to human milk will fill the breasts. Little baby aliens will break the skin with tiny teeth to feed, and that puncture heals/closes up fairly quick!!

Females take a little longer to harden up after a molt, but only by a few days. This is so the body can figure out if it’s going to harden up or stay soft if the females been fertilized

And uh,, that’s all I really have to offer for now for this species!! Feel free to ask questions or drop ideas under this thread ty for those who got this far in my ramblings
