Popular Post Greatsword812 Posted May 19, 2018 Popular Post Share Posted May 19, 2018 Hey all. Obligatory disclaimer, long time luker, first time poster. This prompt came from a write thread on /y/ and is as follows: "Requesting a story about a young man receiving his own GroBot in the mail, and continuing to have fetishy sex with it after activating it. The GroBot should have total sentience, but be submissive to his owner. The owner should just be happy to get his dick wet with his growing android hunk. The only requirement is that theirs lots of growth and sex." Constructive criticism is appreciated. I normally don't write smut (or write at all, tbh) so please let me know if you like it. According to the anon on /y/ the prompt was inspired by rippedsaurian's character. ****************************************** “I didn't fucking order this.” The Amazon guy just stared at me. He clicked his pen again and repeated, “Ya gonna sign or what?” I huffed and scribbled my signature and he bolted out the door leaving me with a gigantic six-foot package sitting in my empty living room. Again, I scratched my head. There was no way I drunk ordered anything THIS big, even drunk me would have balked at the price. I cut down the sides of the package and revealed the inner box that just reeked of expensive production value. Light gray with gold-yellow trim and a shiny matte finish overlay the word GRO-BOT plastered on the side in large sleek lettering. Still puzzled I discarded the front of the fancy box and let out a small gasp of amazement. Before me stood a lean and average sized human looking robot. Much like the color of the box the GROBOT was colored dark gray around the torso and thighs and a dark yellow-gold in the shoulders, upper back, calves, crotch posers and head. The robot had no visible face but did have a V shaped colorless slit on the face that simulated eyes. The bot was also very clearly defined, each muscle group separated and distinct with no body fat to be seen at all, much like an anatomy mannequin. My eyes trailed lower to a small plastic sign affixed to the crotch that said “Please BOOP eyes to initiate start-up.” Following instructions, I pressed my finger to the plastic V shape and the eyes lit up with a cool white light. A small chime signaling start up rang and I watched as the operating system stimulated the GROBOT's muscles in a visible shock wave that ran the length of the body. A few moments later the head turned and fixated on my face. “Initiating Operator Mode. Please specified desired vocal auditory output. Press left pectoral for lower vocal pitch and right pectoral for higher vocal pitch.” The robot cooed. I stared a moment before complying and placing my hand on the left pec. The robot repeated the same phrase in a slightly lower and sexier voice. I immediately repeated and pressed the left pec again several times resulting in a smooth and rumbling base and pressed the eyes to continue. “Growth-based Regenerative Organic-synth Battle-bot for Offensive Training or GRO-BOT.” The bot did a small bow with his hands behind his back before continuing. “Thank you for your purchase, Master.” I stared at the robot, dumbfounded. Taking a few steps back I slouched in my favorite armchair and placed my head in my hands, letting out a great big sigh. The bot had tracked my movements with its (his?) head and said nothing. I saw another bolt of stimulation travel down the bot from head to toe as it stepped out of the box and followed me to the chair, planting its feet exactly a foot from me. “My sensors have detected that your blood-pressure, pulse and respirations are elevated. It appears you are in acute distress. How might I be of assistance, Master?” “Why do you keep saying Master?” I groaned back to the bot. The eyes flashed twice, apparently processing my query. “I am your product. You are my Master.” That did not exactly clarify the situation. “Who bought you?” I inquired, “I do NOT remember ordering something as expensive as you probably are.” More flashing eyes before the bot replied, “My subscription information lists you as the sole and primary subscriber. I am your product. Payment information is restricted.” I stood up and poked the bot hard in the cleft of the pecs with my finger. The bot registered the abuse with a few flashes of its V shaped eyes and fixated its face on mine. Each word was punctuated with another jab to the pecs as I demanded to know, “What. Do. You. Do?” “My original function was to serve as an opponent to humans training to engage in hand to hand physical combat. My architects have determined that I can provide other, more sensitive, uses to non-combat civilian personnel.” The bot replied, coolly. “In summary: I am a sex bot. Do you wish to initiate customization?” That immediately changed my tune. “YES!” GRO-BOT hummed a moment before replying. “Please specific desired height.” “Six feet and four inches.” GRO-BOT began to hiss slightly, like the sound of hydraulics expanding, and his body began to stretch upward slowly. The increased height did not pad itself out however and once completed growing the bot looked too lanky to be attractive, so I decided to up the specificity of my requests. “More weight. Wait! More muscle.” GRO-BOT flashed a moment before requesting, “Please specify body type. Average. Athletic. Olympian. Fitness Model. Body Builder.” “Fitness model!” Cables of new muscle stretched and snapped into existence across the robot's entire body. The sounds of stretching nano-flesh filled the room and GROBOT began to fill out in all the right places. His already defined torso swelled into two slabs of define pectorals complete with an eight-pack of washboard abs and shredded lats. The shoulders were next and each one ballooned out into round powerful bowling balls. Lastly, the arms writhed with new power as the biceps swelled from skinny bumps to powerful tennis ball sized orbs within a few flexes. I moaned out loud at this hot growth and placed my arms on both pectorals, squeezing their newfound hardness between my digits. With a surge of power GROBOT flexed both his pecs as hard as he could, and I felt the warm hard mounds turn to stone beneath my fingertips. My fingers traveled down the bot's torso and down to the fantastic abs on display. The brick like muscles were perfectly symmetrical with a clean divide down the middle that accentuated their power. GRO-BOT raised his arms over his head and crunched his stomach so hard one of my fingers was pinched between two of its shredded abdominal. I was really feeling horny now. My hard cock was staining my pants with pre and I had to let it lose. I frantically dropped the trousers and stood a full attention in front of my new personal sex slave. I leaned back in my comfy chair and slowly began to stroke my length while raking my eyes over the contours of the bot's body. I needed more. “Raise an arm and flex.” GRO-BOT blinked and complied, raising its right arm and bringing it to a firm flex. At his current size the bicep was about a s big as a tennis ball with small veins running beneath the small muscle and up the length of the forearm. I stroked myself faster. “Increase the bicep size by twenty percent.” The veins in the arm pulsed slowly as they supplied the arm with more liquid fuel and after a moment GRO-BOT relaxed his arm and re-flexed. The new bicep was noticeably bigger than it had been before but not quite where I had wanted it to be just yet. Before I could issue a new command, the veins pulsed again and GRO-BOT relaxed and flexed again. And again. And again. With each new flex the arm was even bigger and more defined than before A large vein appeared at the head of the bicep and pulsed with each new flex as the now soft-ball sized bicep grew even further. I was moaning at this inhuman display of power and beat my dick harder and harder until the growth stopped. I immediately let go of my dick to stop myself cumming to soon. I was not going to finish before I had my way with this new robot. “Take out your dick.” GRO-BOT obeyed. The gold fabric posers suddenly vanished and revealed a four-inch soft dick with a grey shaft and gold head. It looked pitiful against the rest of the bot's rock-hard body, so I decided to give my new bot a makeover any man would dream of. “Grow your other arm and jack off while doing it.” The overgrown sex toy blinked once as it processed the request and lowered his new huge right arm to his soft dick while raising the left arm and beginning to flex. The robot slowly began to stroke its own manhood (robot-hood?) in time with the flexing of his arms. The growth started again, first with the pulsing veins. With each flex of the inflating arm GRO-BOT also stroked its own dick to a hard six inches. I was going wild now. I was jacking off furiously and spewing precum everywhere like a leaky faucet. GRO-BOT had completed his growth cycle and relaxed both arms to his sides while his dick, still hard, began to leak its own fluid. My hands flew off my dick and I gasped for a few breaths, fighting the urge to cum early. My mind raced with ideas. How much control did this robot have over itself? How specific could I get? “Increase penis length by two inches.” The bot bleeped again but nothing happened at first. GROBOT's cock continued to leak and then suddenly throbbed back and forth like it was being flexed. Veins spread across the long fuck pole and supplied it with ample fuel while throbbing increased in intensity. The large grey-gold penis stood fully erect and shot a large wad of cum straight into the air. The bot's dick slowly stretched upward toward the sky and fired another round into the air. GRO-BOT reached down, grasping the shaft, and vigorously ran its thumb over the head while the organ finished its growth spurt. The last volley of cum exploded out of the tip like a covered garden hose and the throbbing subsided as it reached eight inches. GRO-BOT blipped again before he spoke, “My sensors detect a rapid pulse and increased perspiration, both indicative of arousal.” GRO-BOT reached out and placed his hands on the armrests of my chair and leaned over me so that I could focus only on his incredible bulk. Veins pulsed on his chest as the bot again flexed his upper body only inches from my face. GRO-BOT thrust his hips and his robot dick made contact with my own weeping manhood. “Do I please you, master?” I did not reply. I had to focus on not cumming too soon or this fantastic experience would be over before it really began. Idea after idea swam through my head of all the new possibilities I had in store with GRO-BOT at my disposal. It appeared he was fully customization and ready and willing to perform whatever I wanted. Do whatever I wanted. Be whoever I needed. “Change your body type to body-builder.” GRO-BOT straightened up and very quickly began to initiate the changes, this time growing outward instead of upward. The growth started at his thighs and began to spread downward. Each pillar of flesh bulged and stretched with new cables of nano-muscle and swelled even bigger around than they had been previously. Each pulse was accentuated by the huge pulsing veins that began to crawl down each length. The growth spurt had then reached his calves which exploded with a small bang into fist sized calf muscles. I let out a moan and quickly sat up in my chair, reaching behind GRO-BOT and grabbing onto his already bulbous glutes. GRO-BOT's behind inflated slowly but surely while I squeezed and manipulated the globes of flesh. It felt like I was holding two halves of a watermelon that kept getting bigger and bigger. Each slab felt tighter and tighter until I felt like they would burst at any moment. Suddenly GRO-BOT clenched his cheeks and thrust forward, slamming his eight inches down my throat. I groaned and gurgled and did my best to suck off this freakishly muscular bot while he continued to face fuck me with long and slow motions. Each thrust slapped his bulbous balls on my chin and after a few moments I grabbed and squeezed them tight. GRO-BOT shuddered and bucked wildly, I could feel his dick throbbing in my mouth as he shot his load again. His orgasm completed, GRO-BOT withdrew from my mouth and stood at the ready, his dick still rock solid. “I-I need you.” I stammered, trying to delay my own orgasm. “I need you inside me, now. PLEASE!” GRO-BOT's eyes blinked. In one swift motion he bent over and hoisted me up into the air by the hips. My hands clambered up his body and I wrapped my arms around his thick bull neck. GRO-BOT was supporting me like I weighed nothing to him! I let out a moan and my legs gripped the washboard abs of his midriff. GRO-BOT shifted me in his grasp and I felt a thick digit probing at my hole. GRO-BOT pressed and prodded at my delicate ass, feeling his way around my taint. The finger retreated and then returned with fresh lube from the prodigious amount of pre spilling from the robot's own cock. I felt him puncture my hole with this slick finger and slowly begin to finger fuck me open. I clamped down on the invading digit and gripped GRO-BOT's neck harder. He was not deterred and continued to slowly finger my hole lose. A moment later the invader was removed, and I heard the robot speak, “You are so very tight master. I will need to insert more than one finger to properly prepare you.” I yipped when I felt two fingers enter me with even more ease than before. GRO-BOT stretched my hole even wider and continued his finger fucking. After a moment I felt him hit my prostate and I let out a long and slutty moan. GRO-BOT continued his prodding once he knew he had struck gold, he sped up and jabbed at me harder. I could feel the hot pressure building inside me and spread from the inside out until I was putty in his hands. GRO-BOT removed his fingers then and grabbed me by the ass with both hands. “It is time.” I felt the head of his cock press against my lose hole and I tried not to tense. GRO-BOT slowly lowered me onto his enormous cock, pressing his head against my hole several times before thrusting through my defenses and sinking me on his thick pole. I gasped and screamed out as he quickly filled me with his entire eight inches. The pain was sharp at first but after a few moments I felt the pain ebb away and was replaced with an intense feeling of fullness. I raised myself up an inch or two and slammed down again, relishing in the pure pleasure of this robo-cock inside of me. “P-Please. Fuck me. Fuck me HARD!” I gasped. GRO-BOT wasted no time and gripped me tightly with both hands before sliding out of my well lubed ass and slamming back in. I could not stop myself from wailing as the musclebound bot begin to fuck me ferociously while supporting my body with this powerful form. I cried and screamed, feeling my tight hole loosen under the intense onslaught of this fucking machine. GRO-BOT did not tire, nor did he slow down. He kept his eyes fixated on me and plowed me deep like the muscle whore I am. I clamped my ass around his cock and was met with an extra hard thrust that dazed me for a moment. His body undulated underneath me, and his rippling abs massaged my own hard dick, I met his thrusts with my own and began to fuck the hard creases of his bulging abdominal muscles while GRO-BOT continued his own onslaught on my abused ass. I was turned on to the max at this point, but the deviant part of my brain knew that I could have even more. “More! More! P-Please I need you bigger! PLEASE! GROW BIGGER AND FUCK ME HARDER!” GRO-BOT's eyes flashed in compliance and I yelped as a sudden pain spread through my ass. It happened again as the huge robo cock grazed my prostate and I felt my hole stretch even wider. He withdrew from my insides until the tip of his gargantuan cock was at the edge of my sphincter. “Yes, master. I exist for your pleasure.” I heard it before I truly felt it. A slow but steady stretching sound beneath me. The next thing I knew the burning at my hole was even stronger and I clamped down again out of reflex. This did not stop the hot pleasure at my entrance as GRO-BOT's fuck pole grew inside me. He invaded me slowly this time and I felt this now gargantuan robotic cock fill me as no one had ever before. I felt him throb with each gush of pre-cum he squired inside of me until he finally hilted inside me. “Are you enjoying this, master?” GRO-BOT queried. I could not answer. Slowly, achingly slowly, he removed his extracted himself fully from my hole and leaned me back, placing me delicately on the furnished chair. I drank in the sight of GRO-BOT's completed transformation and glorious musculature, salivating over his colossal vein ridden arms and titanic pecs that looked too big to be true. My eyes lowered to his now mammoth sized cock. It was by far the most powerful looking dick I had ever seen, easily a foot in length and as thick around as the bottom of a wine bottle. He was continuously leaking precum that slid down his length and dripped onto the floor below. “Master, I must inform you of something.” GRO-BOT leaned down and raised my leg slowly back over my head with one of his pumped arms. My heart raced, and my dick hardened knowing what this hunk was preparing me for. I tried to contain my lust and stall my impending orgasm for as long as I could, but I was close to my breaking point. I needed this fuck so badly it was killing me! Delicately, he raised my other leg until I was spread-eagled, ass to the world, and primed for fucking. “You exist for my pleasure too.” The thrust pierced me with such force that I almost fainted from the sheer overflow of pleasure. GRO-BOT continued his bombardment of my ass with fast, deep, foot long thrusts with the full power of his entire body weight behind them. I was incapacitated from the overdose of endorphins my battered prostate was driving to my brain as this perfect machine plowed me more completely than any human had before. I was delirious with pleasure, numb with pain, and harder than I had ever been in my life. “Your pleasure gives me pleasure, master. I live to serve. I exist to please. The more your desires change me, improve me, the more pleasure I can give. The more leisure you feel, the more pleasure I feel.” As if to make his point he slowed his fucking motion and positioned himself exactly where he knew my joy button was. The monstrous android thrust rapidly back and forth, battering my prostate into submission. I screamed in pleasure and begged him to never stop fucking me. To never cease the endless ecstasy I was experiencing. The droid focused his blank face upon me and blinked in comprehension, his assault on my ass never wavered or even gave the slightest hint of slowing down. I reached out and grabbed onto the massive biceps planted next to my head and GRO-BOT responded by increasing the blood-flow to his already massive arms. I watched the veins bulge and swell as new fuel was pumped into the muscles of his arms, my digits stretched apart as the massive muscle was pumped ever harder under my fingertips. “You are mine now, just as I am yours. No human will ever be able to fuck you as well and as deep as I can.” GRO-BOT's dick swelled again inside me, mid thrust, the spike in pleasure making me see stars. I let out a howl of lust and started beating my dick harder than ever before. He knew I was close, very close. He lowered his body closer to mine, almost smothering me with his muscular bulk. I leaned in and dragged my tongue between his brawny cleavage and tasted real sweat. I latched onto one of his huge perky nipples and bit down hard. I was rewarded with more growth of his lower body which lead to even more explosively hard thrusts. His cum was gushing out of my abused ass with each commanding thrust. I could feel his thick hips slap against my cheeks each time he conquered my hole. And make no mistake, that's what it was. He was sexually conquering me, fucking me as no human ever had or ever could. I could never go back after this. I needed this to be over, for him to finally own me sexually. I needed to cum. “Oh god. Oh please. Oh, oh, here it comes. I”M CUMMING!” I screamed. My balls contracted, and my hips bucked wildly as I came harder than ever before in my life. Stream after stream of my seed splattered all over GRO-BOT's chest as he continued his predatory ass fucking. My vice like grip on his robotic cock only egged him on and he continued to literally fuck the cum out of me, timing his thrusts against my prostate with each volley I shot. I was still shooting when I felt him lean away from me. I watched as the android twisted his nipples and flexed his chest, showcasing his veined pectorals to me in a display of dominance. He held himself upright in obvious orgasmic bliss, straining with all his might as he continued to plow into me and fill me to the brim with this seed. I heard it burst out of my hole and drench the floor below the armchair. I felt my hole stretch each time a volley entered passed my sphincter. I welcomed the heat that grew within me as GRO-BOT unrelenting orgasm raged for a full minute. “S-stop...” I heard myself breath. I was so thoroughly exhausted I almost couldn't muster the energy to speak. GRO-BOT listened and obeyed. He removed his now 14-inch manhood from my gaping hole and hoisted me into his arms. Everything was dim and fuzzy, but I could feel him carry me into the other room and gently, almost lovingly, lay me down on my bed. The last thing I remember was the flash of his eyes before I sank into the mattress and drifted off to sleep. 47 3 9 Quote Link to comment Share on other sites More sharing options...

Hanugumo Posted May 19, 2018 Share Posted May 19, 2018 Kinda get the idea that as the story will progress, the GRO-BOT will grow even bigger and will slowly gain more and more autonomy and more sentience and our dear narrator will become a subservient slave too him. But i also feel like GRO-BOT will be a loving and caring master to him, and will try to make sure his "slave" will accomodate him as long as he can before he will outgrow his slave and all. >;3 1 Quote Link to comment Share on other sites More sharing options...

Greatsword812 Posted May 25, 2018 Author Share Posted May 25, 2018 Glad you all enjoyed my first post here. Chapter two is in the works as of today. Out of curiosity though, should I make a new thread for the new chapter or should I just post it here? Is it possible to update the post title with the day that I upload it or something, so that you all know something new has been posted? Sorry for all these questions but as the profile states, I'm a newbie. Quote Link to comment Share on other sites More sharing options...
