Conner strained against his restraints as he witnessed a couple of aliens have their way with the love of his life, Carmen. He was chained to a simple metal chair in a large room with metal alloy walls covered in paint that was peeling. While the space did have a table with a mattress on it, the graxlians didn't bother using it right now.
Carmen was half naked and pinned up against the grimy metal wall across from Conner. Her eyes were half closed and her face was flush with excitement. The pink haired girl with blue eyes was whining and moaning as the graxlians groped and licked her soft body. The two kissing her were humanoid aliens that looked similar to horned lizards. Their skin was covered in sharp bumps and their eyes moved independently. Rather than human legs, graxlians were digitigrade, with their knees bent backwards and standing on their clawed toes.
With a pinch of a finger and thumb, a graxlian unhooked the bra that was holding back Carmen's large bust. Both soft orbs fell for an inch or two before bouncing. The aliens laughed with low raspy sounds.
"Don't touch Carmen!" Conner yelled impotently. "She's my girl!"
The tallest alien grinned, showing his row of razor teeth, and said. "Let's see if she's liking the attention." He dug his bumpy hand into Carmen's panties and pushed a finger into her pussy. Carmen gyrated and bit her lip as the alien stimulated her. He pulled his hand out and showed it to the restrained man, it was glistening with Carmen's sticky moisture. "Looks like she's enjoying what we're doing."
"I'm so sorry Connor!" Carmen called out. "I don't know what's happening."
The boss alien looked back at Carmen, and said "Accept that your body knows better than you do. Prore and I will simply teach you how superior graxlians are at making human females orgasm. You women are such pushovers." A girthy thick tongue extended from his mouth and traced her pink lips. At first she turned her head away, only for the boss to extend it further and press her lips apart. Carmen stopped avoiding and started sucking on the veiny muscle.
Prore, the boss's subordinate stomped towards Connor. "What do you think of aliens like us using the last breedable woman for our sexual pleasure? The human race will be wiped out because we will fuck her for years until she is no longer fertile. She will be our companion for decades and love every day of it. How long will it be before you are driven insane by this thought? Captain Shleex, how long did it take the last human male to fall into despair?"
The boss took back his tongue and said, "he only lasted a week before he lost his mind, we had to space him for his own good. It was really a mercy." Shleex ripped off Carmen's panties and knelt, his muzzle probed her crotch before his phallic tongue shot out and penetrated her.
"Fuck!" Carmen cried out. Her body tensed and she convulsed.
Prore said, "Ha! A first penetration orgasm! Carmen is a truly perverted woman. Connor, you must not be satisfying the poor girl."
"Shut up you graxlian pig!"
Prore slapped Connor and made him spit blood. "Watch your tongue or you won't even last a week. I'll have you know that Carmen was the one who approached us. She told us that she wanted to know what it was like to make love to a graxlian. Isn't that right Carmen."
"Carmen! That can't be true, don't tell me you asked for this!"
Carmen couldn't look at Connor and simply lifted one of her legs to let the Captain better access her shaved pussy with his girthy tongue. The alien pinned her thigh to the wall and drove his tongue deeper. "I'm sorry Connor, you were just so busy every day. I got lonely."
"I was sacrificing for us Carmen! How could you betray me? How could you throw away what we had?" Tears started to trace Connor's cheeks.
Prore took a finger and collected up a tear from Connor's face and licked his finger. He laughed and bore his teeth. "I don't know what is sweeter, Carmen's willing pussy, or Connor's tears."
"Get away from me!" Connor growled. "I'll kill you."
"Heh, you should be begging for mercy and asking us to let you go. You can live out the rest of your pathetic existence, only without your precious Carmen. We will savor her human flesh, and she will know carnal ecstasy every night. It's only a shame that our sperm cannot impregnate the bitch."
"AhhhhH!" Carmen orgasmed again as Shleex traced circles around her cervix while he ate her out. She reached down and grabbed a pair of horns on his head and pulled him closer.
The captain pulled his mouth away and his tongue made a popping sound as it retracted from her gash. "I think it's time we too show our friend Connor what Carmen was really looking forward to, what she asked for specifically. Get on the table woman!"
Carman stumbled from the wall to the padded table and got up on it on all fours. Prore approached and started to pull down his pants but the captain stopped him.
Putting a hand to Prore's chest. "Captain's prerogative, I get first breeding."
Prore growled but backed off.
The captain approached the table and pressed a small switch that lowered the platform so the alien's crotch was aligned with Carmen's presented womanhood. Shleex licked his teeth as he pulled down his pants to reveal the two erect shafts of graxlian manhood.
Connor gulped and asked, "What? Graxlians have two?"
"Of course we do, puny human! Otherwise we couldn't do this!" The alien used a hand to align both members against each of Carmen's holes and then said, "Come Carmen, you have to do this to show your consent. Show me you want this."
"But…"
"Prore and I will let Connor go and we'll walk out otherwise."
"No!" Carmen started to push her rear against the two shafts. Her pussy lips spread easily, but her anus resisted. After a moment Carmen protested weakly. "I need help, Captain Shleex, please. I want it."
"Carmen! No!" Connor yelled.
"Connor," Carmen said and looked at him. "I was never the pure girl you thought I was. You put me on a pedestal I didn't deserve to be on."
"I will give you what you want sweet Carmen," Shleex said. He wrapped his horny skinned hands around her plump thighs and pulled her down on his shafts. Her anus strained before surrendering and Carmen let out a long and loud moan as she took all the meaty length of the alien cocks.
Carmen lifted a hand to her breast and started to pull and pinch her pink nipple. "Shit! I feel so full Shleex, I can't believe it!"
The graxlian double dongs aligned perfectly with her holes and he pumped her slowly and deliberately. After every few pumps he slapped her ass, making her squeal in delight. "There's a reason why all alien races love human pussy Connor, these women of yours simply crave cock. They want more than your paltry excuse for a reproductive organ. This puss is so tight and wet, I'll never get tired of it. It truly is the best in the galaxy. Women abandoned humanity and sought us out. It truly is a pity your species will go extinct with her as the last girl able to have a child. When we're done with her she won't even look at you. Isn't that right Carmen?"
"Yes captain! I love your cocks!" The girl with the pixie cut pink hair arched her back and stuck out her chest before crying out in another orgasm. "Do me until I'm filled with graxlian spunk!"
"I'm not waiting for my turn, when I hear a horny girl, I help out!" Prore walked around the table to her mouth and he pulled out two alien peckers. He grabbed her pink hair and shoved a cock in her mouth. Carmen moved her free hand from her breast to his free dong and stroked it until pre-cum drooled down her wrist. "Ah surely this slut must have fucked aliens before, she's so experienced!"
"Never! Carmen told me she was a virgin!" Connor said, his voice trailing off as he witnessed her gyrating body and eager oral she was giving the alien's pink prongs.
Carmen couldn't say a word with her stuffed mouth, she only shot him a derisive look before giving loving attention to graxlian cock.
"No!" Connor wailed.
The captain quickened and Carmen's body was soon wracked with the pleasure of another bone shaking orgasm. Her large tits swayed to the pounding she was getting from Shleex and Prore. The alien grunted and buried his penises deep in her round rump and started to twitch violently. Conor could see gouts of purple cream leak from her crotch down her thighs and off the table. Her moans became melodious, which made Connor suspect that she finally got what she was looking for.
"My turn! No more waiting," Prore shouted. He pulled out his cock from Carmen who gave a disappointed look to her new lover.
Now that she could speak, she turned to her boyfriend. "Connor, you're a good guy. I never meant for them to capture you to see this. I thought they would simply do it when you were working. I thought I would then be able to break it to you slowly, and make it less of a blow."
"And lose out on watching him suffer? Not a chance! You humans were destined to go extinct years ago, but to see the last human pair being cucked is so delicious. It will be put in the history books. Connor, your face will be immortalized!"
Prore pushed the captain away and flipped Carmen onto her back. Her entire pelvic area was covered in purple custard like matter. She laughed playfully as she was being manhandled. "Your so strong Prore!"
"Shut up and take my cocks." He thrust hard into her creampied holes and she screamed out in pleasure. He fucked her hard and fast and her tits bounced while he rocked into her.
Carmen's hands shot to Prore's muscular arms and then cupped his face. "Prore, you feel so good inside me. Will you really keep my belly filled with your purple cum every day?"
"I swear it, Carmen. The graxlian empire will do its duty to make sure you never go without cock again. We'll love you every day."
"Yes! The graxlians own this pussy now. You're rock hard!" She brought her knees up to her chest. "Bury your pricks deep inside of me and fill me with your spooge!"
"Bitch! Where were these words when I was fucking you!" The captain pulled her head back and shoved one of his dicks in her mouth while the other one dragged over the curves of her cheeks and cute nose. Her almond eyes crossed to see the free cock. She reached up and started to jack the penis, bending it off in a separate direction. The one plunging into her throat made her neck bulge on each thrust.
Connor dropped head and started sobbing harder as Carmen's moans grew louder. The captain massaged her large breasts, squeezing them to the point where Carmen yelped, he would then roll her nipples between his thumb and forefingers. The pink haired woman's blue eyes became dull as her body surrendered and accepted the endless thrusting of four shafts from two aliens. She gave short little moans on each thrust.
After a few more minutes of furious fucking, the captain yelled out, "You feel too good Carmen. I have to come!" Thick purple ropes of cum filled her mouth and dribbled down her cheek, while strands from the other penis shot out into the valley of her glossy cleavage.
"Ha ha captain I win! Oh shit!" Prore arched his back and shuddered, his eight pack abs hidden behind orange bumpy skin contracted as more graxlian sperm entered Carmen's accepting bum and vagina. The two aliens let out a raspy mating call as their balls released the last remnants of sperm into their new pet.
The captain glowered down at Carmen's face, and said "Carmen, you're now the property of the graxlian empire. You know that right?"
Carmen coughed up a little purple stuff then replied, "Yes. Yes I do, please take care of me."
"Carmen you whore! There was hope that humanity could survive! You ruined it for some cheap thrills?! I hate you! I hate the graxlians! You're all a bunch of bastards! I want you to all fall into a black hole!"
"Say what now?" Captain Shleex said. "How dare you say that of our proud people?"
"Fuck you."
The alien pulled up his pants and walked to Connor. "Say that again."
"Fuck you." Connor then spat in the alien's face.
Carmen was busy slurping up the cum from every portion of her body. She turned and said, "Connor! Please don't make them mad, graxlians have terrible tempers!"
"I don't care! They should all get spaced."
The captain lifted up Connor by the neck and then walked him to the table, he spun him around and shoved his face near Carmen. "Do you see how in love she is with alien cock?"
"Fuck you! I hate you!" Connor yelled out gasping for air. He was about to say more when the captain snapped the human's neck and then extended talons from his fingers. In one swift stroke he drove the razor like claws into Connor with a crunching sound. He then flung the body into the corner. When it hit the wall, Connor's body seemed to spark and then smoke. A few seconds later Connor's body was on fire and the sprinkler system went off. An alarm sounded in the metal room and two aliens covered their small ear holes.
"Oh shit boss, you fucked up." Prore put his hand to his mouth.
The main hatch's seal opened and the round door opened. A husky man with a fire extinguisher came from the portal, his face red with rage. He ran to the burning man and sprayed him with the extinguisher. When Connor's body was no longer burning, he looked up and called out. "Dicia! I've put out the fire, you can turn off the station's sprinklers in the brothel."
A disembodied voice answered. "Fire threat eliminated, sprinklers off." The torrent from the ceiling stopped and the alarm went quiet. The man stormed up to Captain Shleex and pointed a plump finger in the alien's face and yelled, "Cuck droids can only take blunt force trauma, not a fucking graxlian talon you idiot!"
"I'm sorry Rowan, sir!" Shleex replied sheepishly. The alien put up his hands and shrugged. "What he said got under my skin. I'm sorry!"
"You paid extra for that! You were explicit. You wanted the cuck to have more spirit. Those were your exact words."
The alien's shoulders slumped and he looked down.
"You're losing the security deposit for one thing. And from now on your entire ship's crew is denied cuck play until further notice."
Prore walked up behind Rowan and said, "That's not fair! I didn't do anything! I think just the captain should be banned."
"I don't give a shit about what you think Prore, you graxlians need to be put in your place or we'll have so much repair work we won't be able to serve the other alien cultures on the station." He walked to Carmen. "Carmen are you alright? How are your systems?"
Carmen sat up and smiled, showing no signs of arousal. "All systems are nominal. I'll just need the standard irrigation and cleanup and I should be good to work tomorrow."
"Thank goodness, get yourself into the repair bay and I'll clean you up." Rowan said. He smiled and patted her shoulder and then pulled it away wiping his hand on his shirt. "I still don't know how we're going to get Connor back to work, he was the last functioning cuck droid in the sector. Shleex, Prore, get out of here, you'll be fucking blow up dolls for the forseable future."
The two aliens grumbled but backed away before turning and walking out of the room. The only sound left in the room was the ballast lighting buzzing and the drip of sprinkler water. Rowan kicked the table and screamed before slamming his fists into the table. "Fucking aliens!"
