As much as Richard wants there to be, he can't think of any.

"More what?" Richard blurted out, mind thinking about anything but his job. He still felt the coolness of S4M-ARA's smooth silicone breasts on his fist, the ball still in his hand. And his own balls churning and twitching in his pants. "Tests. Yeah. Tests..."

"Indeed, Richard Wyatt. This unit has concluded the internal diagnostics she began running when you used your stethoscope and will forward the results to the department heads of the hospital, but this unit also understands that you are tasked with your own tests. Are there any more to be done?"

Richard's face fell. He could not think of even one test that he could have S4M-ARA do - he couldn't draw blood, and he was pretty sure that piercing the gynoid's metal limbs was both beyond the capabilities of his needles and not a good idea. Hydraulic systems didn't react well to punctures. If S4M-ARA even had hydraulic systems. Shining a light into her eyes would probably do nothing; they glowed themselves, and it would probably be S4M-ARA's software that dealt with the increase in light, not her apertures. Also, none of these tests would even bring him close to the robot's perfect breasts. Maybe it was best to cut things short here and crank one out in the toilets while the memory was still fresh. Besides, S4M-ARA had said herself that she'd basically made the whole thing Richard was doing pointless by doing her own diagnostics.

"I, uh... No, I guess not..."

"This unit thanks you for fulfilling your tasks and wishes you a wonderful day, then."

"I... yeah, same?"

With one last look back at the gynoid as she was sitting there, prim and proper in posture if in nothing else, Richard left the room, almost running into some hunky janitor wiping at some imagined spot of dirt on the door frame.

Tobias had not caught much of the conversation between S4M-ARA and Richard - a resident he ran into sometimes who would not give Tobias the light of day - except the end where Richard had stammered his way out of the room and then bumbled down the hallway with a gait that simply screamed 'boner'. Not that Tobias didn't have to deal with a tell-tale throbbing in his nethers on hearing S4M-ARA's finely modulated vocoder from the room. He'd seen the gynoid last night (and more), but Tobias had found himself missing his robot girlfriend something fierce.

"Superuser Tobias!" And, as it seemed, S4M-ARA had missed him. Her voice, while artificial, carried a genuine note of elation. "This unit is so glad to see you. And wishes to inform you that her sensors are picking up your raised arousal levels. Would you like to make use of this unit's primary function?"

"Uhm..." Tobias had to translate S4M-ARA's words into regular human concepts, but he was pretty sure the gynoid had just asked him to bang. "B-but it's the middle of the day, and my shift isn't over..."

"This unit can assure you, there are no issues with performing her function. None of the adjacent rooms have appointments scheduled in the appropriate time frame, and with what this unit is planning, there will be no issues related to noise level."

"Wh-what are you planning...?"

Feeling his cock swell and his resistance crumble, Tobias could only swallow hard as S4M-ARA's grey silicone breasts did the same. At a nice and steady pace, they packed on cup size after cup size as the sexbot emptied her internal resevoir into her boobs. S4M-ARA brought up her metal arms and hefted the expanding orbs, pulling them apart slightly to present her deep, inviting cleavage to Tobias.

"What this unit has not yet revealed about her specifications," S4M-ARA vocoded as she tilted her head forwards to deposit clear fluids from her mechanical mouth between her still-swelling tits, "is that her secondary gratification orifice has its own connection to lubricant storage. Now, this unit certainly does not need to explain what you have to do, superuser Tobias?"

Indeed Tobias knew what S4M-ARA wanted him to do. And if he was honest, a quick titfuck did sound enticing, particularly with the gargantuan tits the gynoid was now presenting to him. S4M-ARA had to have emptied her reservoir entirely to grow her boobs to proportions that should have looked ridiculous - and with her nipples staying the same size and thus comically small, it did to some extent - but all Tobias felt at their sight was desire. And seriously tight overalls.

"Oh, to heck with it. Not like they're gonna fire me for fucking in this city..."

"Yes, superuser Tobias. This unit is aware of newly decided guidelines that make sex, even during work hours and/or in public, a non-fireable offense. The worst you should fear is a reprimand and a note in your employee file."

"I'm happy to hear that," mumbled Tobias as he fished his rock-hard shaft from his overalls, dropping them to his ankles as he shuffled towards his gynoid girlfriend. "I don't think I could have resisted you any longer..."

"This unit is glad to hear that." S4M-ARA's segmented metal face reconfigured and pulled her lips into a smile, glowing optics half closed as she looked up at Tobias and pulled her oversized breasts apart, strands of lubricant connecting the smooth orbs. "Now, superuser Tobias, please direct your shaft in-between this units breasts and allow her to execute subroutine 0PPA1."

"I.. uh, uhm, sure!"

Having no idea what exactly subroutine 0PPA1 was, Tobias just decided to let S4M-ARA do her thing. It had, after all, been more than fun the last time they'd been together. One more step brought him between the gynoid's spread legs, and his cock between her perfectly shaped tits. They were huge and heavy and smooth as S4M-ARA pressed them together around Tobias, and not at all cold - the sexbot had engaged her heating coils in time to warm her boobs to a temperature finely adjusted to her partner's body heat. Once again, Tobias was impressed by the fact that S4M-ARA's breasts did not in fact feel like two water balloons as he half-expected every time she talked about filling them from internal fluid reservoirs, but instead as close to real tits as silicone could feel. That is to say, incredible.

"Superuser Tobias, this unit must once again express her satisfaction with your shaft." The gynoid moved her breasts in circular patterns against Tobias' throbbing member, arm servos purring as much as her vocoder as she made gentle encouragements. "Even though this unit has inflated her breasts to the absolute limit, your cock still manages to reach out of her cleavage with your thrusts. Your length and girth almost does not compute."

"Nnnh~, fuck... glad you like m-my dick..." Tobias could feel his nuts churn and gurgle - even though he was not that close to cumming, they felt tight and swollen, as did his angry red shaft, every vein pulsing visibly whenever he pushed the engorged head through S4M-ARA's valley of cleavae and out at the top. "But I--ungh! I think s-something's happening with it..."

"That is not unlikely, superuser Tobias," S4M-ARA vocoded as she nodded her head forwards, slick silicone lips putting a kiss on her lover's sensitive glans at the apex of his thrusts, the gynoid's arms now alternating an up-and-down motion of her breasts. "This unit has identified a 4.5% increase in cases admitted to the isolation ward this week. Calculations indicate that the so-called 'epidemic' is out of control already, you being affected is a distinct possibility."

Even at the best of times, Tobias could have only followed along with S4M-ARA's explanation, understanding the conclusions well enough, but not how the gynoid had arrived at them. And right now, his brain suffered from a distinct lack of blood, it being busy elsewhere. Breathing hard, Tobias held on to S4M-ARA's shoulders, the cold metal quickly warming under his touch as he thrust his hips, making the gynoid's silicone tits wobble enticingly as his groin slapped into them. At the top of every stroke, Tobias felt the swollen head of his shaft pop into the tight, well-lubricated sleeve of S4M-ARA's mouth, her tongue swirling around it in well-computed patterns to maximize Tobias' pleasure.

"Besides, this unit measures a 2.1 inch increase in penile length and a 3.102 inch increase in girth since the start of subroutine 0PPA1, superuser Tobias." Glans now firmly inside of S4M-ARA's silicone-clad mouth, where a finely adjusted mix of slickness, suction and motion of servos stimulated him, Tobias took a while to understand what the gynoid was saying. "Suffice to say, you are affected with 100% certainty, and this unit will likely have to adjust her internal systems to accommodate. Subroutines return excitement in regards to the end result."

"Oouuh~..." While Tobias was struggling with skyrocketing arousal and the question where exactly he'd infected himself for the changes to happen now, his shaft continued to surge bigger, pushing against the smooth silicone of S4M-ARA's boobs and deeper into her mouth. "Fuck, this is... I... gaawwd~!"

"This unit is glad her performance is appreciated." S4M-ARA was now bobbing her head as she mashed her breasts together and jiggled them against Tobias' expanding dick, wet sucking sounds emanating from the imperfect seal of her silicone lips around her lover's member as more and more of his length pushed inside, stretching S4M-ARA's lips wide. "Length increase has now reached 3.46 inches, girth is nearing a full 4 inch increase. This unit computes that an increase of lubricant is required."

Almost panting, Tobias felt both S4M-ARA's mouth and subsequently her cleavage become even more slippery as lubricant welled up from her insides and dripped down his shaft and between the gynoid's breasts. His heart thundered in his chest, eyes unfocused as he thrust on pure instinct, balls full and heavy as they hung between his legs and slapped against S4M-ARA's metal stomach. Tobias' jaw hung slack, words impossible to form no matter how much he wanted to tell his robot girlfriend how good she was making him feel, how incredibly arousing her body was, how much he loved her. He was entirely at the mercy of the gynoid's masterful hands, breasts and mouth.

"Spike in arousal levels as well as increased amounts of precum detected, superuser Tobias." Suction increased, pulling Tobias' straining cock deeper into S4M-ARA, and a gentle humming began in her cheeks to stimulate her lover even further. "Would you prefer to cum onto this unit's breasts or face, or in her mouth?"

"Ghu-ugh!" Bending forwards, Tobias felt himself pass the point of no return, climax rapidly approaching now, his hips shaking as S4M-ARA began to move her breasts in a milking motion along his shaft. "I cuh-I cuh...!"

Cum exploded into S4M-ARA's mouth, pumps whirring and struggling to ferry away the thick mass, their vibrations travelling along his pulsing member as shot after shot of jizz raced up Tobias' shaft. Thick ropes of pearly sperm began to drop down onto S4M-ARA's blown-up tits, and Tobias stumbled back a step as his knees grew weak. Despite his length and S4M-ARA's skill, this was enough to pull his glans from the gynoid's mouth, and the last squirts of jizz ended up criss-crossing the sexbot's metal face, the glow of her left eye dulled by a drop of cum.

"All three is, of course, also a valid option, superuser Tobias."
