"Everything looking good, Doc?"

"Yeah, Humvy. Just relax, okay?"

Julian breathed a sigh as he twisted the arm he held in his hands, turning it over to reveal a rubbery, black flesh on the underside, soft and supple. The rat turned on the spot and reached for a small scalpel-like implement that sat on a tray nearby. He scooped it up and hovered it just above the arm before him, pressing a button and activating a laser inside that effortlessly cut down the middle of the rubbery flesh as he moved his hand down. He turned it off mere moments later and gently pried the faux-flesh apart to reveal a mixture of circuitry and tubes beneath.

"Mhmm, mhmm..." The anthropomorphic rat hummed, scanning the contents and occasionally poking one or two with a finger, before he turned towards the table. He reached for a clipboard that sat on the right hand side and, with a pen, began writing something down, before placing a big 'tick' into one of the tiny boxes on the sheet.

"Well..." The scientist cleared his throat and turned. "Looks like the majority of your circuitry is still working and intact. What did you say happened again?"

"I got hit by a car, doctor."

The creature spread out across the table may have looked reptilian in origin, but it was far from it. H.U.M V5, known as Humvy, was a bio-organic AI made with no real purpose other than experimentation. It's name stood for 'Humanoid Utility Machine', and its purpose was, primarily, to serve as an anthropomorphic unit for day-to-day use of the citizens of Altroxa, the biggest city on Ryslat. Humvy, however, was a prototype unit for their latest model, boasting a much sought after upgrade that had been requested since the H.U.M's first inception.

"Hit by a car?" The doctor scoffed, turning to look up and down Humvy's body. This specific model of robot had a shiny black underbody, specifically from its jaw, all the way down its body towards its inner thighs, as well as the underside of his forearms. It had a tail, but it was short and stumpy, and it's legs were digitigrade but articulated, deliberately designed for ease of walking as well as to grab things, to a degree. Humvy's palms had that same rubbery texture as did his soles, though the ones on his hands and feet were textured and ribbed to make gripping things easier. The rest of his body, however, was shiny and hard, made of an incredibly hard to damage alloy that could flex and blend-- the perfect amalgam of metal and elastic. It was, unfortunately, very easy to scratch; that much was obvious from the rugged black mark that Humvy had just above its tempered glass LED multi-expression eyes.

"I wasn't lookin'" Humvy muttered, his tone mixed with the gentle hum of electronics, slightly flanged. "The guards were kind of mad...tell them I said sorry."

"Pff," The doctor turned back to the clipboard. "Tell them yourself. The examination is almost over...somewhat. A tick for your internals, a tick for your external frame, though reserved...no-one's going to get those scratch marks out without a replacement. The last thing is...ah, the prototypes piece."

"O-Oh..." Humvy looked apprehensive. "Ah...that."

"Yes, that," The rat hummed and turned, surprised to see the robot looking sheepish. "What are you getting all embarrassed for?"

"Well, it's..." Humvy began, casting its LED gaze down. "You know that I have realistic sense receptors, right doc?"

"Of course." The doctor reached towards a small box and plucked a pair of gloves free from within, putting them. They looked baggy and loose at first, but after a moment they registered his hand and suctioned inwards, fitting to his hands snugly. He turned to a small bottle of sanitizer and deliberately spread it across the gloves, before he turned, his hands sterile, towards the robot. Humnvy sat awkwardly in the 45-degree angle chair, and with a wave of the rat's hand and the leg portion of the seat shifted and spread, forcing Humvy to spread his legs by extension. Humvy squirmed in its seat as the Rat moved in between his legs, reaching down to his crotch. It was flat and rounded, as it should be, but a light double-tap on the surface with his index and middle finger caused it to open, and out flopped the main feature of the new prototype H.U.M V5-- realistic, fully functioning genitalia.

"Let's see..." The scientist reached down and cupped a sterilised hand under the length of the humanoid-fashioned dick, and Humvy let out a quiet sigh, flanged with that same electronic hum. Most of Humvy's body was synthetic, but parts of its internals were designed to be organic-- specifically, one of those main functions was fully functioning arousal and the production of sexual fluids...to a degree. Humvy didn't actually produce any sperm, of course, but he made something that at least looked like it. As the scientist turned and lifted the member in his hands, it began to grow from the touch, stiffening and twitching as it grew larger and larger.

"Calm down, will you?" The rat scoffed, shaking his head. "Though I usppose this is fine...I need to be sure nothing is broken. So far, however, it seems that the rubber cushioned most of the impact."

"D-Doc, I have a question..." Humvy began awkwardly. "What happens when I get, uh...aroused, when my genitalia protocol isn't in effect? It's not in my internal manual..."

"If it's not out, then signals are sent to your internals to block the flow of faux-blood to your..." The scientist waved a hand. "Basically, if you don't release it yourself, you won't get..."

"Release, right," Humvy continued. "And, uh...who designed the genitalia protocol? I have some reservations about hiding away the genitalia, but leaving the...the butthole exposed."

The scientist flicked his gaze from the pulsing, fully hard 9-inch robotic cock to Humvy's apprehensive eyes. The length of the member itself was made of that same rubbery black material, and as the rat tugged with a hand the 'foreskin' of the cock peeled back to reveal a pink-coloured, but distinctively silicone head. Humvy visibly shuddered and its cock oozed some kind of lubricating fluid, as part of its protocol. Humvy's question was warranted-- the H.U.M had no need to eat, drink or sleep, and so by extension had no need to use other areas of their body for waste. However, Humvy was different; its additional features were intended for sexual use and pleasure, as requested by the general population. Hiding the genitalia was merely to satisfy those who felt it would harm children, but the butthole...it could have just as easily been covered, but some bright spark thought that it was serve to satisfy the BDSM community. Locking away the genitalia via a touch command was effectively akin to chastity, and leaving the ass out in the open...it effectively inspired anal play in any situation. 

The rat shook his head and rose, moving his hand away from the cock and letting it sag, half-hard, whilst a pair of rubbery silicone nuts swung beneath, plump and round. Humvy watched the scientist for a moment before drifting a hand down, lightly stroking himself. It tried to keep quiet, but the hum of its electronics and the fluid that oozed from its member made it audible.

"Genitalia implement...tick," The rat sighed. "Diagnostics are done...how fast was that car going?"

"About 70 miles an hour?"

"Despite that...you are mostly intact, bar a few scratches...but that's fine," The rat turned, looked down, and then shook his head. "Do you really have to?"

"I...It's in my protocol to finish," Humvy lied and looked sheepish, and the scientist shot it a deadpan look. "S...Sorry, it just feels good."

"Finish yourself up and then get back to your quarters." The scientist took the clipboard and strode past it, patting it on the shoulder. "I have to fill in this report."

"O...Okay! Thank you doctor!" Humvy called behind it as the rat left the room, the sliding door clicking shut behind him. Humvy sat there for a moment before its eyes shifted into a sour look.

"Could have at least beat me off..." It grumbled. 

Those that watched the security footage would be greeted to the wet, slapping sounds of a robot masturbating, and they'd look away. There's no doubt in anyone's mind that the H.U.M V5 would be a hit upon release.
