Stimulation Simulation

In my quest to create the next generation of robotics, I am working on a project for a new type of mechaniloid that can perceive feelings and act with its own judgment. I want to create a world in which these robots and humans can work and live together in harmony, and to do that, I must create a mechaniloid that is capable of all human feeling.

In order to do this, I decided to give my newest project parts that resemble humans – though it’s not strictly necessary, there are parts that represent human organs such as the heart, to give these new mechaniloids a ‘heartbeat,’ for example. Keeping with this ideal, I wanted to work on a method to allow the new mechaniloids to feel all types of human feelings, so – well, I may as well stop being so embarrassed about it – I decided to try giving X the ability to experience sexuality.

While my new model will not be able to reproduce through sexual intercourse, human sexuality is a strong force in humans’ emotional spectrum. I want for this new model to be able to think and act on all levels like a human. In order to do this, I had to equip X with the proper tools to perform sexual activities.

My first few attempts at creating a life-like organ for X resulted in failure. I had never needed to create such a delicate part before, and I wasn’t able to get it right. Finding the proper materials proved to be quite difficult, but I eventually broke down and loosened my embarrassment over the subject and researched much more deeply. I had even hired a human subject to examine, and I finally created what would become my final model for this particular piece of equipment.

My experiences in its testing, however, proved to be quite a surprise.

I completed the part, and it was time to connect it to X and turn his power on to test the functionality of his new equipment. I had only tested it connected to a power supply, but I had yet to run it while using X’s thought programs to see if it could respond like a human.

It was late at night – though I had overcome my personal shyness about building things like this, I still would not know how to react if others were to enter my lab at such a time. The lights in my lab were dim and X’s body lay before me on the work table I used to install and modify his parts. I removed the plate that covered X’s groin region in his armor. The skin-tone region underneath was exposed along with the rectangular plug-in slot I build for installing new parts easily – it had helped me greatly after previous failed tests and models.

I sat the plate down on the nearby table and picked up X’s new part. With a click, I was able to plug it in gently, and it fit perfectly. The snug fit made the region look natural, just like a human. Only a very close and knowing eye would be able to tell it was only a robotic replica. I adjusted the scrotum and shaft parts to lay symmetrically at first, possibly just my natural desire for organization, but after staring at the setup for a while, I found it to be somewhat unnatural to rest so neatly. I gently pulled one of the testicles and rolled the shaft to the right side a bit, and it seemed to give the view a lot more human feel.

I was quite proud of my work and took a bit of time to admire it as I flipped the switch under the table that booted X’s debug mode. After a few seconds, the necessary processes had loaded, and the controls appeared on my computer screen on the desk near the work table. After touching a few options on the screen, X’s mind began to receive a program that simulated sexual arousal. I made sure to deactivate most of X’s body parts, even beyond those defaulted not to function while running the debug program. Currently the only part scheduled to respond to stimuli physically was the newly installed equipment.

Only moments later, my newest creation succeeded! I marveled as the lifelike organ pulsed as it would with a rush of blood, slowly growing larger. X’s testicles slightly receded as his shaft grew larger and stiffer with each throb. I almost laughed with joy as X reached his first fully successful erection, indistinguishable with that of a human.

With my eyes, I came up with approximate measurements for X’s new equipment. Just as I had planned, X was a solid 7 inches long when erect, and likewise his scrotum was not too large, but a nice size just above human average as well.

I placed one hand on X’s chest plate to steady myself and leaned in to study the equipment more closely. Every so often, X’s muscles would flex as the arousal pattern program heightened, and the tool would sway through the air a bit. I gently placed my thumb and index finger on each side of the shaft, pulling the foreskin down slowly. My heart began to beat faster as I saw the reddened head emerge from beneath the skin. I pinched a bit at the foreskin to test its elasticity and realism. Everything was perfect.

I touched the monitor a few more times, and I turned off the simulation program and watched with a proud smile on my face as X’s penis slowly softened and twitched back down to its flaccid state. As it grew smaller, I noticed a small bead of ejaculate form on the exposed head as it retreated back into the foreskin. My heart skipped a beat, as I it had slipped my mind that I had created a mixture to replicate human semen.

I was becoming more and more excited about the project. Formally I had mentally prepared myself for the required actions for the second phase of testing, but now I had no inhibitions and it seemed that I strongly desired to continue testing. I didn’t take time to contemplate where these impulses had come from, but I was quite enjoying the success of my project.

With X still running, but with no direct simulation programs, it was time to test the equipment’s reaction to physical stimuli. I removed my gloves and hurried to the sink, washing and drying my hands quickly, anxious to continue the procedure. I returned to the table, and suddenly had an impulse to change a bit of the deactivation in X’s body parts. I breezed through the computer menus and now a few more of X’s parts were functional. Still nothing major, but I was excited to see the reaction in X’s body.

I again placed a hand on X’s chest, and I cupped my other bare hand around the entire new part. I gently moved my fingers to massage the area. I could tell that X was becoming aroused a bit, but I wanted to take things slow, so I removed my hand. The test was a success, and X remained mostly flaccid, but was slightly larger than normal.

I pulled back the foreskin around the shaft with my thumb and middle finger while inserting my index finger to get a feel for the ejaculate I had saw earlier. It was only a small drop, but it stuck to my finger in a long string as I pulled it away from the head. One of the newly activated parts responded – X’s hips slightly moved away from the table he was laying on.

I chuckled a bit and looked at X’s sleeping face, “You like this, don’t you X?”

After my sarcastic joke, it was time to see if I could fully arouse the penis into an erect state with only physical stimuli. I cupped my hand over his equipment once more and began to squeeze and fondle the part a bit more vigorously than before. As expected, the programs responded positively and I could feel the part began to bulge under my hand.

I stood up more straight and moved my other hand from X’s chest. I tugged at X’s scrotum with one hand and gripped the shaft with my other hand. X’s hips lifted from the table again, and his fingers began to twitch a little. My experiment was running flawlessly! I barely even had to think about what to do next, everything was moving so naturally and perfectly.

I started to stroke my hand up and down across X’s shaft as his hips rhythmically began to move opposite my motions.

“That’s a good boy, X.” I muttered to myself as I continued to proudly stroke the now fully-erect shaft in my hands.

I began to forget about the testing and was wrapped up in my newest masterpiece. Everything was going so well. I continued to pump my hand over X’s beautiful member as I squeezed at his balls, watching his fingers writhe as his hips thrust up toward me. I stared at the red head of his cock getting closer and closer to my face as a bead of pre-cum emerged and started to dribble down toward my hand.

My eyes were fixated on the seeping juice, and without even thinking, I noticed it was getting closer and closer to me. Almost in a trance, I now had my face right up to X’s erect, dribbling shaft. I took my hand off X’s balls and started to run it down his leg, feeling the cool metal under my hand. I continued to jerk X’s cock and before I knew it, I was running my tongue over the head, lapping up the bit of cum trickling over. I could feel X throbbing harder and harder under my thrusting hand.

I continued to grow more and more excited. I couldn’t keep myself back, and just using my tongue didn’t satisfy me any longer. I wanted to fully experience the success of my new project. I let X’s long, hard cock glide into my mouth as he slowly thrusted deeper inside my throat. With the hand that was previously stroking X’s hot shaft, I began to reach toward X’s face. Without any thinking or reasoning, I placed a finger on X’s lips, pressing slightly to part them. The lack of reaction seemed strange, and I suddenly snapped out of my trance.

After a moment of confusion, for the first time I noticed that there was a pain between my legs. I realized immediately that I had become erect myself, and my own cock was now bulging in my pants, pressing against the fabric locked down by my belt, begging to get out.

I decided not to stop and think about what was going on or what I was doing. I was enjoying the experiment too much to worry about that now. With one hand, I started to unzip my slacks, and with the other, I feverously navigated through computer menus to activate X’s mouth parts. As I finished turning off the locks, I managed to pull my throbbing shaft out of the front of my pants. X’s hips were still thrusting with desire as his wet shaft started to soften a bit.

“Don’t worry, my son,” I said to X, though he could not hear or interpret what I was saying while running in this mode.

Immediately I shoved X’s cock back into my mouth and began bobbing my head over the juicy shaft, rolling my tongue around the hard member. I used one hand to stroke myself slowly while I reached to X’s mouth with the other. This time when my middle finger began to press against his lips, he parted them himself. I let my finger enter the new opening and felt a wet, warm tongue begin to explore around my finger.

I hummed over X’s cock as I put another finger into his mouth, enjoying the warm feeling enveloping both as I reached deeper inside his throat. I took my hand off my own shaft to stroke X’s again and gave my mouth a break while I stared at X’s soft face sucking on my fingers. It gave me a new idea.

Pulling my chair over from my desk, I quickly stepped up onto it and climbed up onto the work table. It was very large and sturdy, so I was not afraid of it falling as I positioned myself and stood on my knees above X’s head, facing down toward his body. My heart was pounding with so much excitement that I thought my chest was going to explode.

Hurriedly, I tumbled forward over the table and adjusted the position of my knees, holding my body up with one hand and trying to line my cock up with X’s mouth with the other. I got the positioning right and felt the tip of my cock part X’s lips just like my fingers had before. I slowly moved my hips to ease myself down inside X’s hot mouth. As the warmth stretched around my throbbing shaft, I couldn’t help but to let out a pleasurable groan as I traveled deeper toward X’s throat. His tongue began to caress around my shaft, and I slowly slid my member back and forth into his mouth.

After a few moments, I had the hang of the rhythm, and while I let X pleasure me with his mouth, I returned the favor on his hungry cock that was waiting for me. I groaned over his cock and lost track of time and completely forgot about my surroundings.

That’s when I heard a sound. I wasn’t paying close attention, but I knew it was a very familiar sound. It was a clicking or sliding sound… something I heard quite often. Something told me that it was not a good sound.

“Doctor, I was—“ as a voice arose, my eyes widened and I felt an icy chill run from my head to my toes; it was then I recognized the sound as the door opening.
