Reciprocation

30 minutes ago....

BANG!

Private Rebecca Snee expected to find at least one Luxrn hiding in the command center behind the reinforced door when her superior Sergeant Liza Makarova kicked the obstacle down in order to restore communication and reclaim the colony Zeus from the Luxrns and regain foothold to mount a counterattack against them and the terrorist group known as the Black Tigers.

What she wasn't aware of was several Black Tiger soldiers hiding in the room and having two mind-controlled Luxrns in their control nor the flashbang that appeared right in her superior's face. Both female marines screamed as they dropped their rifles as they were disoriented form the attack. Rebecca is lucky enough to be far away from the blast but Liza took the full brunt of the flashbang.

Her vision recovered faster and managed to see several figures coming out of the door. But before she could take action, she saw a dark figure appearing from her field of vision and knocked Rebecca and her superior down to the floor, knocking the air out of them. She barely had time to react before she felt teeth pierce through the flesh of her right shoulder that caused her to scream in pain as she was then dragged away from Liza.

"Sergeant!" She cried out to Liza who was quickly being surrounded by Black Tiger soldiers and a Luxrn which has a collar around its neck which quickly pounced on the Russian Sergeant's back. She wanted to save her but first she needed to get free and kill the Luxrn dragging her off. She was obviously outmuscled but Rebecca wasn't going to go down like a total wimp.

"Get off me!" Rebecca screamed as she beat her free arms against the the hardened skin against the alien wolf, hitting it as hard as she can. The Luxrn felt the blow, but that only served to anger it as it bites down harder that earned another cry of pain from the private.

When they were back to the cafeteria area, the Luxrn the throws Rebecca into the air, causing he to collide with tables and chairs that were sent flying as she screamed in surprise. It didn't help that she landed on her bad shoulder that further caused pain. She got to her hands and knees but the Luxrn rams its head into her side, making her wheeze out in pain as she slid across the floor and slam into the table as the alien wolf lunged at her with claws out to rip her into shish kebab.

Rebecca raised both her feet and held the Luxrn at a distance. But the Luxrn proved relentless its claws had managed to shred the Private's front military vest which exposed her skin and her bra-covered chest as Rebecca also sustained cuts now and then. She gritted her teeth as she felt her strength fading fast and the Luxrn's claws being a few inches away from ripping her into pieces.

With what strength she felt left, she took a knife from her pocket and waited for the inevitable death as she decided to go down fighting the Lxurn. "I'm sorry Sarge." She whispered to her superior as Rebecca is prepared to make a valiant sacrifice.

But just as the female marine was about to accept her fate, a shrill screech echoed through the area which prompted them to pause. The Luxrn's eyes widened as it whipped its head around as if it was trying to sense where it came from, giving Rebecca some space. Soon, an air vent flops down from their right side as a black figure drops down to the floor, giving a predatory hiss.

"No way....." Rebecca gasped as she saw none other than a Xenomorph coming into view. She remembered in the history books that humanity had waged war with the Xenomorphs two centuries ago and while they suffered hundreds of thousands of casualties, the Xenomorphs were driven off and haven't been seen since.

The Luxrn had no time to react before the Xenomorph pounced on the the alien wolf and the two aliens began to brawl. Despite the sheer brutality being displayed by the Luxrn, the Xenomorph's ferocity and superior range via his tail gave it the upper hand as the alien wolf was now howling in pain from being stabbed multiple times

With the Xenomorph was bust mauling the outmatched Luxrn, Rebecca used her good arm to drag herself away and to find Sergeant Liza Makarova, hoping to God she'd still be alive. "Gotta find Sergeant. Gotta find Sergeant." She muttered to herself as she winced from the cuts she'd sustained earlier, each movement greatly increasing the pain. But she moved forward nonetheless as the Luxrn is being mutilated.

She was halfway from her destination when she heard hissing behind. Rebecca turned her head and felt her heart come to a near stop when she saw the Xenomorph crawling towards her. "No, no, no." She panicked and began limping faster hoping to reach Liza in time. But her hopes were dashed when the alien decided to leap in front of her and confronted her. Rebecca stared at the alien's eyeless face with fear as his tail raised up, posing to strike her.

The female marine closed her eyes and hung her head low, waiting for his tail or inner jaw to pierce her head. But she felt a prick to her neck and felt drowsy all of a sudden. She opened her eyes suddenly and saw the alien's mouth formed into a smirk as she closed her eyes once more and her head hit the floor with a soft thud.

(^)(^)(^)(^)(^)

A groaned escaped her lips as the private slowly opened her eyes, a burst of white enveloping her vision. Rebecca raised her bitten arm to block the light but they widened when she realized her arm the Luxrn had bit was no longer sore. After her vision cleared, she noticed that her arm had been bandaged and that she was lying on the couch in one of the offices in the abandoned facility.

Rebecca sat upright and noticed that her top had been removed, leaving her bra-covered chest exposed to the cool air. Her scratch marks healed but left scars in the process. "What happened?" She said as she rubbed her head, soothing the headache. But her head shot up when she heard some hissing at the other end of the couch. The Xenomorph who'd saved her from the Luxrn popped out and Rebecca yelped as the alien crawled forward while tilting his head.

She tensed as the Xenomorph sniffed her chest as his head moved up and down. But to her shock, the Xenomorph then lowered his head and laid his head on her lap, nuzzling. Stumped by the actions, she reluctantly reach forward and patted the Xenomorph's head, noticing how smooth the warrior alien's head is.

"Uh..... nice Xenomorph?" It was more of a question than a remark. But the Xenomorph purred as he enjoyed her hand rubbing his head. Despite their history in the past, it seems the Xenomorphs are willing to forgive them. Slowly, Rebecca let out a small smile as she relaxed and began to get affectionate with the Xenomorph, who were once their enemy and now is the same one who saved her from the Luxrn.

After removing her hand, the Xenomorph stretched its claws to reveal a a phone it'd taken from one of the Black Tigers. Rebecca took a look closer and her eyes widened from what she saw. On the phone was the Xenomorph Queen, chained and being pierced by tubes all over her body. And something clicked.

"Is that why you returned here? The Black Tigers..... have taken your Queen and began experimenting on her?" She questioned and the warrior Xenomorph nodded his head as Rebecca thought it over. Suddenly, it made sense on how the Black Tigers were able to take mind control the Luxrns, they'd been experimenting on the Xenomorph Queen and using her psychic abilities to create those collars.

"I don't suppose you know if Sergeant is still alive?" She asked the alien, to which the Xenomorph tilted his head at her question. Then, he nodded and began crawling on all fours and Rebecca was more than happy to follow him to where Sergeant Liza Makarova was being kept.

3 weeks later....

Rebecca tuned out the flashes as she fired her pistol at her targets with precision that only veterans could achieve as the cardboards were riddled with bullets. After emptying the clip, she ejected the magazine and quickly reloaded with another before taking aim and begin unleashing rounds to another batch of her target. Once again, she managed hit them in the head or dead center in the chest.

When she was done with her target practice, Rebecca sighs while taking off her ear muffs on placing them on the table next to her. "Nothing beats target practice to relieve stress." Rebecca chuckled and put the weapon on the table and began stretching her arms, until she stopped and started sniffing her arm, she then cringe from the foul smell. "Man, I really need a shower." Rebecca said took off and began heading to the shower stalls.

Upon being reunited with Sergeant Liza Makarova, who was also saved by the Xenomorphs, she told her surprised superior that the Black Tigers had taken their Queen captive and had been experimenting on her hive mind ability, hence why they were somehow able to control the Luxrns with their collars. Liza reported this to the council and despite their previous conflicts with the Xenomorphs, much like they did they did with the Zoktroks of today, they decided to put their differences aside in order to fight the greater threat, which are the Black Tigers and the mind-controlled Luxrns.

With the help of their former enemies, the UEEF ha managed to locate several Black Tiger bases in which they were manufacturing those collars that they'd experimented on the Xenomorph Queen. The coalition of the UEEF, Zoktrok, Vulkros and Xenomorphs are more than enough to overwhelm the terrorists and they began losing ground. Losing thousand of members to the alliance.

As Rebecca made her way to the shower stalls, she'd failed to notice a lone Xenomorph, the same one who'd saved her from the Luxrn, hanging from the ceiling, its head tilting as he focused his attention on the female human and begins silently following her. After their Queen had been rescued, the Xenomorphs were more than ready to repopulate their numbers with the help of their formers enemies, particularly the females as they were more than eager to taste and feel Xenomorph cocks after Liza had fun with hers.

The Xenomorph saw the brunette female soldier stopped near a door and headed inside. He simply crawled over and watched as Rebecca began stripping of her uniform, then to her underwear before becoming completely nude. She has a bodacious hourglass figure with E-cup breasts and perky nipples.

Unaware of her Xenomorph looking at her from above, Rebecca got into the shower and turned the faucet, letting warm water hit her dirty and oiled skin as she sighed in relief. After getting wet enough, she grabbed a nearby shampoo and began washing her hair, enjoying the scent as she cleaned herself after hours of non-stop action and recon.

The Xenomorph cautiously moved down the ceiling as Rebecca remained oblivious to the alien making his way towards her as she rinsed off the bubbles in her hair. It is when Rebecca's hand reaching for the soap that the Xenomorph made its move, closing the gap between them and wrapping his arms around her waist and his head against him as Rebecca yelped in surprise from the sneak attack.

"Shit!" Rebecca gasped as she turns her head, only to sigh in relief as she she sees the Xenomorph hugging her as he began massaging her nude body with his claws, caressing the female human as he nuzzled his face on her neck. "Ngh~." Rebecca moaned as the Xenomorph's hand moved to her breasts and started groping her her chest. The alien being careful not pierce Rebecca's tits as he groped her. Rebecca's body shakes in morbid excitement as she is molested by the Xenomorph as she placed her hands on the walls to prevent herself from buckling under the pressure.

After getting groped by her alien ally for a bit, Rebecca felt some disappointment when the Xenomorph's hands detach from her huge chest. But her eyes widened when something began poking her puckered asshole. She glanced over as the Xenomorph grabbed her waist and was in position to enter the female soldier's ass, his eyeless face looking for permission. Rebecca bit her lip as she contemplated for a bit before giving. "J-Just go slow for now." She requested as she turns back and took a deep breath, waiting for the fun to begin.

With a low hiss, the Xenomorph's cock slowly entered the female human's asshole, the anal walls stretching out to make way for the thick shaft and continued until all 11-inches of the Xenomorph is inside her. Rebecca gave a moan as she feels full from the cock. Her moans got louder when the alien got faster with his thrusts as her breasts bounced in his clawed hands.

Her legs clenched up repeatedly every time the Xenomorph's cock enter her backside. Rebecca's pussy on the other hand start leaking love juices from how she was getting turned on by having an alien fuck her asshole. Her arm reached for the alien's head and clutched it tightly as if hanging on for dear life as she was pounded.

The Xenomorph hissed with delight as his cock speared through the female soldier's tight asshole. His hands gripping her waist and pulling her back to him as he thrusts his appendage into that tight passage, Rebecca's smooth skin rubbing on the Xenomorph's hard carapace as the hot water skin their bodies. Her breath ragged as she was taking an alien cock up her ass. She's seen a lot of Xenomorph smut in fanfictions she'd read, but never would've imagined she'd get fucked by a real one.

The human-alien intimacy continued for a while, but then the Xenomorph began to hiss as his thrusts began to fasten before hilting his cock deep into Rebecca's ass and screeched as he explodes inside Rebecca. Her eyes widened and gasped as she felt hot alien cum enter her anal walls. "Oh!" Rebecca moaned loudly as she felt lightheaded from the climax, her body shaking and her hands clawing the wall for the Xenomorph's head as she rode her orgasm around. Sweat mixed with hot water as the female soldier is being creampied by her alien lover. His clawed hands squeezing her soft tits but never leaving a scratch.

This lasted for 30 seconds before the Xenomorph stopped cumming, though he still remained hard inside her. Rebecca panted as she planted her face on the wall, exhausted from the climax and the feeling of Xenomorph cock up her ass. She briefly closed her eyes for a moment, but they open wide again when something crawled up her leg and trying to probe her unoccupied pussy. She looked down and saw a yellow spider-like alien wrapping its tail around her waist. Rebecca immediately knew it was a Facehugger.

The Xenomorph gently clutched her hand when the female soldier's hand reached down to remove it, prompting her to look at his eyeless face. It clicked in Rebecca's head that he brought the Facehugger, but not to impregnate her with a Chestburster. "I-I see." She nodded and retracted her hand before spreading her legs, giving the Facehugger enough space before moaning as the spider-like alien thrusts into her pussy as she squirmed and moaned while being held by the Xenomorph.

Soon, they were back in action, this time the Xenomorph laid beneath Rebecca as she had her legs up in a full nelson position. "Oh yes!" Rebecca moaned loudly as she was being her holes were being abused by a Facehugger and a Xenomorph simultaneously as she was double teamed. Her jiggling tits bounced as her body rocked up and down while the Facehugger continued to thrust into her pussy.

His thick cock kept hammering away at her ass as her buttcheeks clapped against his hips, creating wet fapping noises as the Xenomorph rutted the female human's tight asshole, hissing whenever it squeezed his cock for its cum. The Facehugger kept thrusting its appendage into her cunt, making squelching noises as he was enjoying her pussy. Rebecca's eyes rolled into her her and her tongue hangs out as she was double teamed by her alien partners and she loved it.

Bits of her love juices flew as she bucked her hips against the two alien cocks in her holes. It was one thing to feel an alien cock in her, but two at once made Rebecca feel like she was on cloud nine. The threesome continued for nearly 10 minutes when the Xenomorph hissed as he and the Facehugger began swelling up inside her before cumming in Rebecca. Rebecca moaned heartily as she was creampied in her pussy and ass by their twitching shafts.

Cum leaked from her pussy where the Facehugger was positioned in and dripped down to the floor which was eventually washed away by the hot water. Meanwhile the Xenomorph's cum stayed inside her Rebecca's asshole due to her tight asshole preventing any from exiting. After a while their climaxes wore off and Rebecca gave a sigh of relief when the Xenomorph pulled out with a pop though the Facehugger was still attached to her. However, she felt the Facehugger still hard inside her with eh Xenomorph looking the same and she had an idea.

"Mm~" After a minute of two of resting and turning the shower off, Rebecca was on her hands and knees as she sucked the Xenomorph's cum-covered cock, humming in delight as she tasted her juices and his cum on it. The Facehugger, having his fill with her cunt, moved up to her ass and began thrusting away with his cock spreading her asshole once again. Both her holes were used by a Xenomorph and a Facehugger. Now that's something Rebecca can brag about to others who can barely handle either one solo, let alone both.

Her tongue swirls around the black shaft in her oral orifice while bobbing her head back and forth, enjoying the sweet flavor of her own fluid and the salty Xenomorph cum. as she suckled on his cock as the Xenomorph hissed in pleasure at the feeling of his female partner giving him a good blowjob. He moved his hips in the same rhythm so that his balls gently slapped against Rebecca's chin.

The Facehugger simply moved his cock in and out of the female soldier's ass in a slow and smooth pace, content on dragging it out to reach his climax for a second time. The tail wrapped around her waist as he rutted the human's ass to his heart's content. Sweat clung to Rebecca's brown hair and body as she was anally pounded by a Facehugger while giving a blowjob to the Xenomorph. She could've left the shower open to make it hot and wet but she wanted to avoid wasting too much water and getting scolded.

Eventually, both aliens reached their end and came inside. Rebecca gagged as warm salty Xenomorph cum was deposited into her mouth and down her throat while her ass was filled once again. Nevertheless she gulped down every load while wiggling her hips to prolong the Facehugger's climax, her pussy leaking cum now that there was nothing plugging the white substance in.

A minute had passed and their orgasms had finally calmed down. The two aliens pulled their cocks with out a pop and Rebecca could gasp for air once it was out of her. Rebecca assumed the W-sitting while licking her lips to catch any semen that she hadn't eaten yet and sighed once she was finished. But she then gasped when she felt hot water hit her skin again and saw the Xenomorph had turned them on again, having witness how it worked.

Rebecca sat on her ass with both holes filled with alien cum exhausted and dirty from the threesome, but ultimately satisfied. The Xenomorph got behind her and cuddled next to her as he nuzzled her neck, whereas the Facehugger crawled on top of her pussy and rest on her lap. Rebecca smiled as she turned her head to kiss the Xenomorph while caressing the Facehugger below her.
