"I would like to perform fellatio," replied SUVI.

Your finger hovered half an inch from the screen as you frowned, brain not quite processing what the AI had requested for a few seconds. When you turned to SUVI's head she was smiling pleasantly at you.

"Did you say... you wanted to give me fellatio?" you asked her, feeling a rise in your chest.

"Yes, Doctor," she said. "And indeed you are currently the only viable candiate to perform fellatio on. That is... a blow job... or head job... suck off... oral sex... deep throating... " You stared at SUVI with a quiet awe as she listed off the various terms for the exact same act she wanted to do to you. "I have been reviewing the files I was given on this particular sexual activity since you gave me this mouth," she explained. You looked at said mouth, her blue lips wet and oddly inviting. "I believe that providing sexual pleasure to a partner may enhance my own and expand my understanding. So I would very much like to try it."

This was, of course, the plan all along, but you didn't expect SUVI to become this forward this quickly about her sexual 'desires'. She was advancing at a faster rate than you had anticipated, but decided that this was a positive thing. It was oddly arousing to hear this detached head speak so technically about wanting to suck your dick and you were already firming up underneath your jeans. "I also find you to be in alignment with my preferences, Doctor," she continued, her powerful eyes studying you. "While you have been the only person I have interacted with so far, I find your particular facial features and head structure conform strongly to my parameters defining attractiveness. I find your... piercing stare... to be most appealing." She blinked at you and you could only blink back. Then her gaze drifted down from your face as she went on. "This also triggers my curiosity module and I require immediate data on other parts on your body. Right now, in particular, I would like to observe your penis, in both aroused and flaccid states."

Right now you would only be able to provide her data on one of these states. And since this was her request and was part of her 'curriculum' anyway, you could only oblige.

"Alright the, SUVI. Let's get started then," you said, unbuckling your belt. The AI watched with interest as you stood and undid your fly then fished out your ready erection. SUVI's expression, eyebrows high and mouth slightly agape, pleased you.

"You are already aroused," she stated. "Your penis is larger than I had estimated based on your height and weight." At this you shrugged modestly. The shifts in SUVI's face as she studied your swelled member were fun to watch. The way she knitted her eyebrows, licked or bit her lip, as she observed every inch of you, felt flattering. You heard her sniffing now and the sensations seemed to make her expression ripple, SUVI's eyes closing a moment. "Olfactory receptors detect your pheromones," she said, voice lowering in volume, a small amount of drool seeping out from the corner of her lips. "I would like to use my other senses now Doctor..." she continued, her staring at your cock almost trance like. "Will you put it into my mouth please?"

With complete confidence in your work you had no hesitations about sticking your dick into this untested android's offered opening, potential dangers that such an act might entail already accounted for with programmed and physical safeguards in your designs. You smiled, stepping closer to SUVI's face and she lowered her jaw. She only had a limited range of motion and leaned forward with her neck as you pushed your hips towards her. She had breath that you could feel on the tip of your cock and then you were engulfed in her eager mouth. SUVI's artificial tongue explored you immediately as she accepted you deeper. You decided to stop with her blue lips wrapped about at about halfway along your shaft and let yourself enjoy the sensations inside the warm wet orifice in the android's face. Her tongue was fleshy and dexterous, soft and pleasantly slimy. She had tiny taste receptors along this flexible appendage and she was using every nanobud to study and evaluate your flavours. When her Neural Systems interpreted the data SUVI was made to moan softly around your cock. She began gently sucking, drawing more of your now freeflowing precum into her mouth, pooling on her tongue and sending more sensation and data to her processing unit. She moaned again, longer, swallowing, apparently enjoying the taste of you.

You were enjoying the experience too and put a hand to her cheek, your warm touch making SUVI eyes shift to look up at you. There was a simulated sense of wonder in her wide eyes.

"You're doing very well, SUVI," you told her, now gently starting to thrust into her mouth. "That feels good." That encouragement made her try to lean forward more, though her head was still anchored by the cable so she couldn't make an appreciable advancement on you. You pushed in deeper then, sliding more of your throbbing cock past her lips until you reached the squeezing tightness at the top of her throat. On the mainframe screen you saw centers of her brain map pulse brighter as her built in gag reflex was triggered. The android choked on you and you unblocked her 'air'way for a moment, allowing SUVI a second to relax before jabbing forward again. She hummed around you, her eyes squeezed shut as she tried to relax her throat, fighting against her basic responses and readjusting what were acceptable parameters for her body. SUVI's training was not only mental but physical too, the synthetic materials of her unfinished body capable of growth, damage and self-repair like the real flesh it simulated. A droplet of saline fluid was squeezed out of her artificial tear ducts and SUVI blinked at the sensation, drooling more and groaning.

You decided then to pull out, withdrawing your length steadily as SUVI's jaw slackened. Sticky synthetic saliva splattered onto the floor as you popped away from her lips, the excessive drool running over the AI's chin. She didn't gasp but was motionless for two seconds as she processed that last experience then looked up at you. "How did you find that?" you asked her, cock dripping in her spit just a few inches from her face.

"Challenging but enjoyable," she replied, slurping and swallowing as she closed her mouth. "And warm. You said I made you feel good?" asked the 'innocent' android.

"Very enjoyable for me too," you said smiling.

"Yet not enough for climax or ejaculation," she noted, now eyeing your cock hungrily. "I shall need to work on my technique." You ran a hand through her the hair on the side of her metalic skull and she tilted to your grasp.

"Well that initial test was for you," you explained, moving your hips forward again and pressing the head of your cock to her soft lips. Her mouth opened to accept you as you plunged back into her head. "Now we'll finish the test for me." You took her in both hands and started to thrust more. You didn't push all the way down to her throat this time, instead letting her tongue and cheeks, and the gentle vacuum of her mouth provide you all the sensation you needed. SUVI hummed, finding a kind of comfort in the way you gently rocked her head back and forth as you fuck her. She looked up at you, recording the expressions you made and noticing the increase in your heartrate and shift in breathing pattern. The sensation of your cock hardening more around her lips and suddenly swelling made her position her tongue under the head of your penis as her programming dictated. "I'm gonna cum," you told her, voice urgent, feeling a heat surge through from the base of your hot rod. SUVI moaned as you unloaded into her and she uploaded your data for processing. As your semen hit her tongue and slid down her throat she vibrated, interpreting and tasting the slick and gooey fluids. "Fuck... ahhh... SUVI..." you breathed, pulsating in her mouth as you continued spurting. You filled her and she sucked, drinking you with a gentle thirst that made you want to cradle her head for as long as possible.

Finally you were emptied. Sensing a cessation of new fluid data SUVI relaxed her lips as you pulled your cock out. She closed her mouth, tongue probing behind her teeth to scoop up any remains, wanting to ensure all of your data was processed fully. Her eyes meanwhile never left your flagging member, continually studying the way it wilted and skin retracted until you stuffed it back into your pants and sat down.

"Phew... well done SUVI," you complimented the program who found herself smiling at how soft and serene your expression was. "Analysis; personal responses," you commanded her, feeling a little too spent to hold a proper conversation in the moment. She swallowed one last time before answering.

"The warmth of your body... the heat... was notable. The sensation of your undulating erect penis in my mouth as you ejaculated was gratifying," she began, eyes sparkling brightly. "The taste of your semen was mild, slightly salty but otherwise not unpleasant in flavour. The fluid was viscous and a little oily in texture and slid easily down my throat. My throat..." there was a pause in SUVI's report where if she had a hand she might have brought it up to touch her neck. "Your penis ... which I am developing a preference from my files to call your cock... your cock reached nearly to my pharynx at one point and my protective reflexes signalled panic centres in my Neural System... however I understood that I was in no real physical danger and thus pleasure centres were subsequently activated in tandem. I would, if the Doctor enjoys it, like to increase my ability to take more of your hard cock down my throat."

"Noted," you said happily, managing to keep a straight face. SUVI seemed glad for the acceptance too. "You also produced a large volume of semen," she said. "More than most specimens recorded in my files." At this you chuckled and leaned a little closer to SUVI's face.

"Well I tend to give a little bit extra when it's for a pretty girl," you said, brushing loosed strands of her silky hair from her face. Blush filled her cheeks, her silvery, slightly translucent skin turning a warm shade of purple, though SUVI's expression didn't yet know how to shift around appropriately to fit it. She smiled though.

"You use flattery as part of your courtship rituals," she said. "Acting as if I am a real lifeform yet still acutely aware that I am, by your definitions, still not truly sentient. Not fully conscious."

"That's true," you said, though not bothered by SUVI's analysis in the slightest.

"When will you deem me sentient, Doctor?" she asked. "How will you know?" This line of questioning was part of SUVI's programming and you nodded to yourself. This was, of course, a tricky thing to pin down for scientists and philosophers alike. There had been decades of discussion and debate on the matter and the only thing everyone agreed on was that nobody could agree on what it truly meant to create real sentience being as opposed to only simulating it convincingly. But you had your own test for this, and a hunch that it would be simple and easily identifiable as true once it did happen.

"I will know when you do," you said simply. "You will tell me."

SUVI looked blank for a moment then tried to nod, the cable pulling taught behind her.

"Very well, Doctor," she said, though there was an hint of uncertainty to her voice. She paused again. "Do you really find me pretty?" she then asked. You grinned and nodded genuinely. "I also find you to be ... handsome," she said, smiling too. "And I find your cock aesthetically pleasing."

You couldn't fault SUVI for her good taste and went back to the body map, the android's eyes swivelling back to the screen with purpose.
