This is an incredible find! Two years ago, a squad of USCM marines were deployed to our research colony on REDACTED to investigate a complete communications loss. All hope seemed lost until we got in close enough to pick up live feed from one of the marines' helmet cameras, and it turns out the alien lifeform we call a xenomorph they've been studying had escaped containment, and turned the whole facility into a new hive. As horrifying as the outcome of the facility and it's staff is, what we found in the footage really shed some new light on this remarkable species' ecosystem. It really enlightens us as to what the xenomorphs use for sustenance in the hive. Like any normal life-form, it needs to metabolize some form of sustenance in order to function.

Typically, after being subdued by warriors and drones, humans that were captured were knocked unconscious and dragged back to their hive for impregnation via facehugger. But footage captured by one of the USCM detachments seems to suggest a whole new class of xenomorph in the hive's caste, and that some of the human hosts taken back to the hive might serve another purpose besides being used to spawn more xenomorphs.

At first the human (only male) is bound to the wall in a separate chamber with the same organic resin used to suspend the potential hosts for facehuggers, but his lower garments are removed or torn away, revealing his genitals, and often always in a seated or laying back position. We still do not understand what it is that determines who becomes a host, and who becomes a prisoner to these new xenomorph workers. After identifying some of the captured marines in the footage, they all held remarkable PT scores and clean medical histories. It seems they picked the strongest and healthiest males for this role.

Then come in these new workers. They can be distinguished by having bodies far more humanoid in appearance, with buxom and voluptuous features, such as wide hips, thick thighs and calves, semi-muscular arms, and rather enormous glands on their chests, in addition to a pair of rather large, succulent lips, all of which appear relatively soft, as they're seen jiggling in some of the footage. More importantly, they exhibit female genitalia, and chatter from the captives seem to also suggest it is often always tight, with upward rippling walls, and a constant sucking effect.

Interestingly, they act incredibly docile and we'd see these new feminine workers rigorously mating with the captive males on a daily basis, whether they're awake or not, be it riding them in a missionary or reversed position, or orally sucking on their penis, ever so eagerly trying to collect their sperm. When compared to normal members of the caste, their behavior is mighty unusual. When they're not briskly riding or sucking their captives raw, they still seat themselves on the captive's lap, penis lodged inside their nethers (sometimes slowly riding them). This new class of xeno also appears to exhibit maternal traits, as in this state, they'd smother the captive with affections - i.e. licks, kisses, playful bites, kneading and caressing their bodies and heads.

They'd continue to vigorously mate with the male captives days on end, but in between sessions (usually when the captive wasn't capable of climaxing anymore, or seemed to take too long to do so), they'd appear to slow down or stop to turn and face them to press those engorged, breast-like glands into their faces, making the captive breastfeed from them, and take in a strange, green syrupy fluid. It was unclear as to what purpose this served, but within moments of ingesting this strange fluid, the male captive was immediately fully erect once again, and biometric signs from captive marines' armor suggest it acted as a potent cocktail of nutrients and hormones that left the host fully energized and rejuvenated. The captives describe the fluid being either rich or tangy, with a sweet, syrup-like consistency, and dangerously addictive.

Again, we didn't understand the purpose of this until the course of the next week and a half, we'd notice the glands on their chests expanding, to the point where the soft plates covering them were beginning to gradually come apart, revealing the transparent chitin between, and the creamy contents within. The biggest they've grown to was perhaps twice their original size before they'd vanish for a few days, only for another one of these 'milkers' to take their place. Likely so the ones at peak capacity could feed the members of the hive, as they often return with their breasts reduced in size. One surviving marine suggests it all mostly goes to the Queen. Then the ones that appear to have shed their load will come back and relieve the ones that have filled their glands entirely. Rinse and repeat.

It would appear that the semen collected in their stomachs via oral or vaginal means, accumulates over time, and is converted into a protein and nutrient enriched syrup. It's unclear how this process works, but all in all? It seems they function and serve the same purpose to the hive as Honeypot ants do on Earth. Seems we won't truly know until we've obtained one of them.

Standby for further analysis...

UPDATE - 10/07/2159
Captain Rodriguez and his boys recently captured one of these new xenomorphs alive, and it strangely seems to take to the containment very well, it only passively-aggressively responds to attempts to make contact with it, but we know better... These are crafty and cunning creatures.

UPDATE - 10/10/2158
For the last three days, it keeps watching and following us through the glass, giving me and Riley both very inviting glares... Licking it's lips at us and pressing those swollen glands, or it's large, wide posterior back against the glass, and that glistening, virgin-like entrance toward us...

Riley put his crotch to the glass a few times, and it licked at the glass or pushed it's arse back against it. It's actually kinda funny watching him dryhump the glass... Though, in our case? It's perhaps one of the second best things we've got this far out...

UPDATE - 10/13/2158
It's been real hard getting any work done... With how it keeps teasing and seducing us over to the glass. Leading us over to the door, as if asking us to step inside or freed it... We know we can't, at least not without containment suits and restraining it...

It's appearance and behavior really isn't helping a man like me... The nearest lady that could really ease my growing frustrations is light years away... And this... Creature is right behind a glass wall I can get behind with the swipe of a card, and looks mighty eager to see me... I really don't know how long I can take this torture...

... I'll wait until my shift comes up, wait until Riley is asleep...
