Chapter 4

It was earlier than Nate had cared to be awake, but his escort had already lost another 2 days when they had to make the detour to help Goodneighbor. Nate had gotten up to shower, leaving Cait and Magnolia still intertwined in the bed. The room, and Nate had smelled so much like sex that he simply couldn't justify skipping a shower this morning. Cait had grudgingly woken up in his absence and joined him in the shower. Thankfully she was not in a playful mood so they were able to shower relatively quickly. As a matter of fact, Nate had just stepped out of the shower and was dressing when he heard a knock at the door. "Come in!" He called out. He was busy fastening his belt when he heard her cheerful voice, "Good morning monsieur." Nate froze and looked up, standing in the doorway sporting her trademark shorter hair and smile was Curie. "Curie! It's so good to see you, how are you?" The last time Nate had seen Curie was when she had asked him to help her become human. Dr. Amari had been able to transfer her consciousness into a discarded synth body (much to Cait's disgust), but it had taken so long for Curie to learn some basic motor and societal functions that Nate had been forced to leave her behind when he was still fighting the Institute. She had also developed a bit of a crush on Nathan which had only exacerbated Cait's animosity towards her. Now here she was, smiling at him while he was half naked, next to a bed where Magnolia was completely naked and visibly showing the signs of her treatment the night before.

Curie however, seemed oblivious to everything in the room, but Nate. "Oui monsieur, it is very good to see you again. I am well! Dr. Amari 'as been kind enough to teach me much about 'ow to be 'uman. As a matter of fact, I was 'oping to ask you for a favor." Nathan finished dressing and asked, "Yeah sure what do you need Curie?" Curie looked at him with almost child-like innocence. "Well I was wondering, if I might accompany you on your journey to ze Castle. It 'as been some time since we traveled togezzer and I zought I could benefit from anything you could teach me about being 'uman." Before Nate could answer, Cait burst into the room from the bathroom, completely naked. "Oh no ya don't!" She rounded on Nate. "Don't ya dare tell me ya'd actually consider taking this tin can with us! She can barely function, how would she fight if we needed her to? What does she know about being human??" Throughout Cait's outburst Curie had been a silent observer. She had not reacted to Cait's aggression or the fact that she was naked. In fact, if Curie had not spoken up now, Nathan might have thought she was somehow oblivious to the whole exchange. "'Ello madame Cait. On ze contrary, my abilities 'ave improved since we last met. For example, I am aware that you are currently naked. Nathan was also naked just before my arrival indicating that you two were bathing togezzer just moments ago. By Magnolia's current state, and ze smell in zis room, I would say zat Nate and Magnolia engaged in ze 'uman mating ritual of coitus eizzer with your permission or per'aps your active participation?" Cait looked furious but Curie continued. "Additionally, I 'ave also been equipped with advanced combat capabilities. I am proficient with ze pistol, rifles, shotguns and most laser weapons. I 'ave also been programmed to 'arm no 'uman unless ordered to do so by Nathan."

The silence in the room was almost deafening. Although Nathan knew he would suffer endless grief for it later, there was only one answer he could give. "Sure Curie. We leave within the hour though so hurry and pack and meet us outside the State House okay?" Curie beamed, "Oui monsieur, zank you very much!" She turned to leave the room but paused and looked back at Cait. "You 'ave very symmetrical breasts and buttocks madame Cait. I can see why Nathan would choose you for his sexual mate. I 'ope we can be friends given time." With that, Curie turned on her heel and left, while Cait stomped back to the bathroom fuming. It's going to be a long journey to the Castle he thought.

"PUNY HUMANS!" Nate had to duck as the super mutant fired his laser rifle. The laser missed his head by inches. "Cover the General!" Lt. Hale called out. There was a burst of gunfire, and Nate heard the super mutants cry out in pain and anger. He took that as his cue and dashed quickly from behind the burned out vehicle he had been hiding behind and ran as fast as he could for the corner of the next building. He had only just made it when a mutant hound appeared as if from nowhere and clamped his leg in its jaws. Pain radiated all up and down his leg, and he found himself howling in pain. Cait stepped forward and fired her shotgun into its head twice, "C'mon you stupid bastard!" The hound released its grip with the second shot, and Cait and Hale both dragged Nate behind the building. Blood was pouring from where the hound had bit Nate, he felt as if he would pass out any minute. Two of the Minutemen provided covering fire while Curie applied a stimpack to Nate's leg. The group retreated further down the alley, carrying Nate and trying to give him a few minutes to rest while two of his Minutemen stood guard at the corners, firing every so often to keep the mutants at bay.

"Can you walk General?" Lt. Hale asked him over the gunfire. Instead it was Curie who answered. "Lieutenant, I do not recommend ze General walk for at least anozzer few minutes while 'is leg completes its healing." Lt. Hale looked simply furious. "We do not have another few minutes woman!" He yelled. "Those mutants are eating us alive with that minigun. We need–". Whatever else Hale was going to say was lost as one of the Minutemen at the corner yelled, "Suicide mutant!" The group turned just in time to see the Minuteman fire his rifle a split second before the corner of the building came crumbling down under the explosion of a plasma grenade. The dust had not even cleared when the mutant with the minigun appeared at the end of the alley and opened fire on the group. Nate, Hale, Cait, and Curie were already kneeling and were able to dive into cover, but the remainder of his escort was quickly cut down by the minigun. Each time Hale or Cait tried to return fire, a hail of bullets threatened to tear them to shreds. "Excuse me monsieur." Curie was annoyingly calm about the life or death situation they were currently in. "Would you like for me to activate my combat protocol at zis time?" Nate hesitated. He didn't want to risk Curie's life, but the thought of losing Cait was even greater. Curie at least could be rebuilt if something went wrong, couldn't she? Nate had to choose, "Yes!" He yelled, "activate combat protocol!"

He turned to face Curie but she had disappeared. He only had a few more seconds before his cover was completely torn to shreds. All of a sudden, the mingun stopped firing. Nathan, Cait and Hale poked their heads out from behind cover to see that the mutant's head was now rolling down the alley. His brethren stood frozen in shock before another one of their own went down, his brains now on the outside of his skull. "STUPID ROBOT!!" The mutant had at last spotted Curie and was trying to engage her in hand to hand combat. Curie swung her sword at his arm, but the mutant knocked it away and then lifted Curie up by her neck. "I am. In need. Of assistance." She choked out. Nate took aim, but before he could fire a shot, Cait had taken down the mutant with a single blast of her shotgun. Curie fell to the ground. Her clothing was torn and she had huge hand marks around her neck but she appeared otherwise unhurt. "Zank you madame Cait. I very much appreciate it." Cait helped her to her feet. "Nice moves for a tin can." she said. Finally able to feel his leg again, Nate stood up with Hale's assistance. "C'mon General," he said somberly. "Let's get you home."

The next week went by in a blur. After arriving at the Castle, the Minutemen had sent a group back to the Brewery to retrieve the bodies of their fallen comrades. On the second day, Nate had met with his council, who told him what the Minutemen and Commonwealth needed from him in order to solidify the Minutemen's position of power in the Commonwealth. They wanted to launch an assault on the town of Quincy and liberate it from the Gunners. Quincy was where the Minutemen had been betrayed and fallen from grace in the eyes of Commonwealth. Only then, the council had said, would the Commonwealth see that the Minutemen's strongest days were ahead of them and not behind. Nate had reluctantly agreed, and even now, his council was going over battle plans and strategies to present to him the following day.

Nate had just returned to his private quarters after such a meeting. Cait was taking a nap in their bed but stirred when he entered the room. "It's sooo boring here." She sighed. "When can we return to Sanctuary? Ya know I hate being here." Nate kissed her. "I don't know why you're being so whiny, we're planning to take Quincy. Next to fighting the Institute, it'll be the largest firefight we've had yet. I'd think you were up for something like that." Cait snuggled closer to him. "I'm always down for a fight ya know that. I just wish we had more time alone together. Fightin' and fuckin's the way to live, but lately I haven't got to do either!" She pouted. "Well I'm sure we have time to fix at least one of those right now," Nate suggested. Cait smiled and kissed him before disappearing under the covers. He felt her unzip his pants and then her lips were around his shaft. He had just settled in to relax for a few minutes when there was a knock at the door. Nate hesitated, but from under the covers Cait said, "'s'alright darlin', I don't mind an audience. Besides I'm under the covers." Nate shrugged. "Enter."

The door opened and Curie stepped into the room. "Sorry to disturb you, monsieur but– oh 'ello madame Cait." Sure enough at the sound of Curie's voice, Cait had stopped her work and glared out from under the covers at Curie. "What do ya want tin can?" Curie did not react to the insult but stated, "well I 'ad a question concerning ze prototype of some new weapons for ze Minutemen, but it looks like you two were about to engage in ze act of reproduction, yes? I understand zis need is a vital one much like eating, but I 'ave very little data available to me on zis subject. Might I observe? I promise I shall remain silent." Cait stared pointedly at Curie until Nate said, "You did say you like an audience babe." Cait sighed, "True. I just need me some cock. Yer cock. So if robobitch promises to not be weird then fine, I don't care. Now take off yer damn clothes Nate, and YOU–" she pointed at Curie, "You do what I say when I say it, got it?" Curie nodded. It had been over a week since Cait and Nathan had been intimate so Cait wanted the full experience.

Nate slid her pants off, and pulled her to the edge of the bed by her legs, where he pressed his mouth against her lips. Cait moaned and her hand grasped a handful of his hair. He moved his tongue all around her lips until she squeezed his head between his thighs as she climaxed with a loud moan. She stood up and stripped off her shirt before dropping to her knees. Her head bobbed up and down as she worked, but she didn't wait for Nate to finish before she stood and turned away from him bending over the side of the bed and pulling her cheeks apart for him. "I want it in me arse. Do it now darlin'." Nate didn't need a second invitation. He slid himself in slowly as Cait winced, but then let out a soft moan. Even after as many times as he had taken her this way, her ass was still so tight. He thrusted into her, but had only gotten a dozen or so strokes in when all of a sudden the wailing of the Castle's siren could be heard throughout the fort. The Castle was under attack. "No don't stop!" said Cait. "Please don't–" her next words were interrupted by a very loud noise that sounded like part of the Castle's wall had collapsed somewhere. "Oh hell– go on!" Nate pulled himself free from Cait and dressed as quickly as he could. Curie watched him with interest. He had forgotten she was there. "Curie with me!" He yelled as Cait was still searching for her own clothes.

Nate and Curie burst out of his quarters and into the courtyard. Several large mirelurks, led by an even larger mirelurk queen were attacking the Castle. "Curie get to the armory. Get me something to take down that queen!" He yelled. "Oui monsieur!" and just like that she was gone again. Nate's Minutemen had managed to take out the smaller mirelurks but the queen was proving too much of a challenge. If it moved any closer inside the Castle, it would be able to bring down the radio tower the Minutemen used. Nate took shouldered his rifle and took aim at the soft undershell portion. The mirelurk queen let out a shrill sound when he fired before it swiped at him, knocking him across the courtyard. Then Cait was there with her shotgun, blasting away at its legs. She emptied a several blasts into one leg before the creature stumbled, losing its balance. Cait dodged when it swiped at her and she disappeared from sight behind the other side of its shell. Nate looked up and saw Curie aiming a rocket launcher, unaware that Cait was just on the other side of the mirelurk… "Curie wait!!" It was too late. Curie fired the launcher but it must have been modified because two rockets launched at the same time to hit the queen in the under part of her shell. Smoke and pieces of the mirelurk queen covered the area…

*

"I'm going to kill her when I get out. She's going to need a whole new body by the time I'm done with her." Cait was lying in the medical wing of the Castle where she had been for the past day. Nate himself had spent the night in the wing until Cait had regained consciousness. When the rockets had struck the mirelurk queen, it had fallen partially on Cait's leg breaking it. Thankfully, Curie had developed a treatment to cut the healing time down drastically. "She didn't see you Cait," Nathan said. "She already feels terrible, besides you need to rest. I'll come back to see you in the morning." He kissed her goodnight as she drifted off to sleep.

*

Nate opened the doors to his quarters and was surprised to see Curie there when he cut the lights on. "Curie? What's going on?" Curie looked as if she had been crying. "I 'ave 'ad some strange feelings since madame Cait was injured," she said. "I know it is my fault, and I 'ave tried to make amends but I still 'ave a strange feeling that drains my energy and clouds my judgement." Nate now understood what was going on. "Those feelings are guilt Curie. You feel them when you make a mistake, especially when someone gets hurt like Cait did. Just continue trying to make amends and they will go away soon enough." Curie nodded. "I believe I 'ave done much to make amends with madame Cait. My treatment 'as sped up her 'ealing and she should be ready to leave ze medical wing in anozzer couple of days. Is zere anything I can do for you monsieur? I know madame Cait is your friend and mate. I am more zan 'appy to accompany you as your bodyguard as she did should you need to travel outside ze fort, or fetch your meals? Per'aps I could clean your armor or perform madam Cait's mating duties?"

Nate had started working on cleaning and repairing his power armor while Curie was talking, but at her last words he dropped the rag, and wrench he had been holding. Turning to face Curie, Nate cleared his throat and said, "Look Curie, I-uh-appreciate the offer," he stammered, "but that's not really how our, 'mating rituals', actually work. Besides, I don't think you actually know how to do anything– do you?" His last question was more out of curiosity than anything else. Curie's face changed from passive to noticeably animated with the turn this conversation had taken. "Oui monsieur, you are correct. I do not know exactly 'ow zese rituals are done, but remember, you allowed me to watch you and madame Cait begin ze ritual a few days back. I know somewhat of what would be required of me, and I trust you to teach me 'ow to perform zese duties. I swear to do whatever you command me to and you may use me 'owever you wish. If it is a matter of concern to you, I shall tell you, my status as a synth allows me to remain free of disease, including zose of a sexual nature. Furthermore, if you allow me zis privilege of participating in such an important 'uman ritual, I shall store ze information in my memory processor which would allow me to create a separate protocol, much like my combat protocol, zat you could utilize at any time."

Nate had never felt more conflicted. He knew that Cait detested Curie and synths in general, but no one could deny the fact that she had enjoyed their group rendezvous with Magnolia back at Goodnieghbor. He himself wasn't sure about whether he saw synths as being truly sentient either. Curie certainly looked human, sounded human, but she still lacked much of the social interaction skills that would help her blend seamlessly with actual humans. Would he be taking advantage of her if he said yes? Would Cait be upset? More than likely Cait would be upset, at least initially anyways, but then again–maybe he could also teach Curie to be more like Magnolia… Nate threw down his cleaning rags, and took a deep breath. He crossed the room, and locked the door to his room. He had made his decision. "Remove your clothes Curie." Curie smiled, looking simply elated, and hastily undressed, while Nate did the same. Nate had crossed back to his bed, but when he looked up, Curie was still standing there waiting for his next command. It was then he realized he would have to give her very clear and direct commands.

"Come here Curie, stand in front of me." Curie moved to obey and Nate took stock of her body. He had never seen her naked before. Curie had a slim form not unlike Cait's and her breasts were slightly smaller, but perkier. Her nipples were also smaller, but a very similar shade of pink that was almost imperceptible against her pale skin. Her synthetic body lacked any pubic hair, a fact that Nate found interesting since Magnolia had also lacked hair. Maybe it was a synth thing? On the other hand, Curie's ass was surprisingly larger than Cait's. He had never really looked at it before, but now free of clothing, he saw how large and shapely it was. He ran his hand from her face, down her side and then grasped one of her cheeks. It was firm, and larger than his palm. He no longer had any hesitation.

Nate rubbed his fingers between her legs, and Curie let out an involuntary moan. Once she was wet enough, he slipped his fingers inside her and moved them until her thighs squeezed together, and her hands moved towards his out of reflex as she climaxed. "Oh monsieur!" she breathed heavily. "Zat was amazing! Zat was ze female orgasm was it not? But you did not climax no? Please monsieur, what is your next command?" Curie was still breathing heavily, but her enthusiasm had not changed. "Get on your knees in front of me Curie." She did so without hesitation. "Now open your mouth." Nate placed himself insider her mouth once she obeyed, but Curie simply held it there waiting for further instructions. Nate decided to take matters into his own hands, and grabbed Curie's head with both hands and began thrusting himself in and out of her face. The sound of Curie gagging, filled the room, and when Nate looked down, he saw that she was staring up at him intently, waiting in case he had further commands. He noticed that semen and saliva were flowing quickly all down her front. "Use your tongue to stimulate it, Curie," he breathed. "Swallow it. As much of it as you can." Curie obeyed without hesitation and the sounds of her slurping replaced the gagging ones.

Nate felt himself getting close so he pulled Curie's head away from him, and watched as the separation caused more saliva and semen to drip down her chin and onto her chest as she gasped for air. It was time to teach her another technique. "Stand up Curie." She moved to obey and Nate moved her closer to the bed, placing her hands on the edge of the bed and spreading her legs slightly apart. He pushed her down so that her back arched, and he positioned himself behind her. "Hold this position until I say otherwise Curie." Nate hesitated for a split second. He knew he couldn't last much longer with Curie so he needed to choose where he was going next wisely. But then he remembered that this was Curie's first time. There was only one option for his current situation so he took it. "Okay Curie, where I am going next may cause you some pain, if the pain becomes too much I want you to tell me okay?" Curie's voice gave no indication of fear. "Oui monsieur!" Nate spread her cheeks carefully. He had been inside Cait so many times that he wasn't sure how gentle to be with Curie. He placed the tip against her lips and pushed, gently at first until the tip was completely inside.

Curie let out a gasp and flinched, but held herself still after recovering. Nate continued pushing until he was completely inside her. He felt Curie stiffen as she fought through the initial pain, but she remained quiet as Nate buried his shaft completely inside. Nate moved himself in and out slowly, before he started pushing himself more aggressively. He hadn't given much thought to how it would feel but he couldn't help but notice how Curie was very wet as he moved himself in and out. Still she remained silent, the only sound in the room was a soft squelching noise that came from between her legs every time he pushed in. As her legs started to shake, Nate slapped one cheek hard enough to leave a red mark. He placed one hand on top of her cheek and pushed his thumb inside her ass. Again, there was a slight tensing of her body, but aside from that she remained quiet as he worked. Realizing that Curie cared little for her own pleasure, and was doing this solely as a learning exercise, Nate decided it was finally time to take things up a notch.

He grabbed her roughly by the hips, and proceeded to thrust as hard as he could. He could see her eyes closed and her mouth open with pleasure in his mirror, but still she was quiet as he used her. Nate around to fondle her small breasts, and he felt himself getting close. He was breathing heavy now from his efforts, but he was so close he couldn't stop. Finally, with several last thrusts, he felt himself explode as he pulled her by the hips tight against his body. It was only now that Curie spoke, "Oh monsieur," she breathed. "I believe I can feel you relieving yourself inside me now. What a most fascinating and pleasurable experience!" Nate continued with smaller thrusts until he was completely spent, and as he pulled himself out he slapped her ass for good measure. Curie maintained her position as he withdrew. "Zat was quite pleasurable monsieur. Shall I reposition myself or would you like to use anozzer orifice? I believe zat you seemed curious about one in particular and I 'ave seen you use madam Cait's before." Nate took a deep breath. He was so spent he wasn't sure he could stay up much longer. "We'll save that lesson for another day Curie, but I do need to be cleaned. Come and get on your knees in front of me again." Curie did as told and with Nate's direction, she used her mouth to clean him from shaft to tip and back again. She was still covered in semen and saliva from his first use of her mouth.

When Nate was satisfied, he ordered Curie to stand and had her deactivate her newly named, "mating protocol". Nate laid down in the bed, and ordered Curie to lie next to him. Although her mating protocol had been deactivated, she still obeyed enthusiastically, and the two found themselves falling asleep in each other's arms. As Nate closed his eyes, his last thought was of how he couldn't wait to teach Curie so much more.
