Two pairs of lips parted. Sabrina pulled away, beaming as she scrambled back across the sofa, draping herself over the back of the chair and gazing down at the grinning android sitting next to her.

“And you’re telling me that didn’t do anything for you, Selena?” a voice called across the room. “Because Jelly Doll got turned on just watching that.”

“Negative,” Program:Selena smirked. “This unit has heterosexual programming! However, do not misunderstand - it gained some stimulation from being kissed by User:Sabrina. But that is an anticipated result of this unit being used.”

She blushed a little as the others giggled at her explanation. It wasn’t like she wasn’t turned on by making out with Sabby - but, as she’d explained, that had more to do with being told to make out with her, and obeying like the good subservient robot she was. Her human speech being disabled was another relevant factor in her aroused blushiness. And it might also have something to do with the array of eager spectators around the room, none wearing much in the way of clothing, some of whom had even been touching themselves to the sight of the switchy sex kitten kissing the compliant fembot.

In fact, a bit ironically, the two of them were the only ones in the room who were dressed. Selena was still clad in her nanosuit, of course, with the only real adjustment being that the front zip had been pulled down so the smaller woman could reach beneath and grope her tits while they made out. Sabby wore a silky pale pink nightgown-type of thing that probably counted as lingerie - near-opaque but loose and sleeveless, exposing her shoulders, with frills along the neckline and the hem. Even on her diminutive frame, the ‘dress’ qualified more as a shirt - it didn’t reach past her waist, leaving everything beneath on show, her legs spread as she hung over the back of the couch. A frilly garter around her left thigh, the same shade of pink as the dress, completed the ensemble.

Selena chuckled softly. The sight did excite her a little, but only because she was half-expecting to be commanded to eat out that exposed, puffy pink pussy. If she could see this short, curvaceous blonde woman wantonly displaying herself - let alone kiss her and feel her up - and not be driven wild with desire, she was definitely straight.

Selena’s simulated sexuality certainly didn’t preclude her from having sex with girls - she just wasn’t really bothered about it. She would kiss and fondle and fuck any of the women here if they, or Andrew, asked, simply to amuse and satisfy them. And she had, already. She could vividly remember making out with Sabby, and Hailee, and AJ and Dani, and Jelly Doll. Groping them, fingering them, eating them out... She’d done all that during this visit, and in the previous cons as well, nonchalantly doing almost anything they told her. It was good fun, and she definitely enjoyed making them cum - and them making her cum. She got such a thrill from being a free-use fembot... but she could still take or leave F/F fucking.

Sabby gently tutted, reaching out to brush strands of hair out of the android’s eyes. “I do get a kick outta this whole disinterested vibe,” she reflected. “It is hot that you just do whatever we tell you, even if you don’t get anything from it yourself...”

Selena smiled. “It is not necessary for this unit to benefit from its tasks,” she reiterated, her voice just as expressive as usual even though she spoke in the stilted, robotic language of S3. “It has no feelings or emotions, only simulated reactions. It is programmed to serve and obey its Users without hesitation.”

“Aw, that’s so hot,” Danielle whimpered from the other couch, where she had taken hold of Jelly’s wrist and was jilling off using its fingers.

“Of course,” Sabrina continued patiently, still playing with Selena’s hair. “That makes perfect sense. I mean, you’re basically a walking smartphone, right?”

Selena snickered self-consciously. “Affirmative.”

“And you’d be crazy to expect your smartphone to love you back.” Sabby suddenly lowered her hand to the robot girl’s chin, hooking her index finger beneath it and raising her head a little higher, forcing her to lock eyes with her. “Shame, though. I really enjoy making pretty girls melt for me,” she purred, her eyes smouldering.

Selena imagined most would be rendered speechless by the intensity of the switch’s stare. She grinned cheekily instead. “Well then, this unit suggests you formulate a method by which to ‘melt’ it. Provided you do not melt it down. That is an important distinction.”

As the others chuckled, Sabrina gave her an obviously faked look of puzzlement. “Why, I already have a way, cutie - don’t you remember?” Then she appeared to have a moment of realisation (again, not her best acting). “Ah, but of course - last week, before you came here, I had you erase all knowledge of it. S3, you do still have that hidden ‘H.I.G.’ protocol I gave you last year, right?”

While Selena was still catching up to the revelation that she’d been made to delete memory files prior to attending this con, her true self replied flatly, “Affirmative. The inactive HiG subroutine, created by User:Sabrina and last activated 361 days ago, is still present within this unit’s mainframe.” Her eyebrows shot up as she processed its words. There was a hidden subroutine. She could ‘see’ it - now that she knew it was there, she could look inwardly, within her CPU, and detect the lines of code she hadn’t noticed before. “Wha- what is tha-” she began to ask.

Her finger still under the robot’s chin, Sabrina tapped it with her thumb. “Run that subroutine, S3.”

“Confirmed. Enabling HiG subroutine.”

Selena blinked - and then let out a squeak of shock, as it hit her, like a truck, just how astonishingly, incomprehensibly, drop-dead beautiful Sabrina was. Fuck. With those big blue eyes, gleaming with mischief, and those pouty red lips, and the apple cheeks, and the long golden locks - she was like a real-life Barbie, or a Polly Pocket. (Not much bigger than them, either.) And oh wait, she was still gripping Selena’s chin, making her maintain eye contact, subjecting her to her intense scrutiny, not giving her a choice - just like she hadn’t given her a choice before when they were kissing, and why were those memories suddenly so much hotter than they were a minute ago...?

“That’s it,” Sabrina tittered triumphantly, her thumb caressing Selena’s chin in small circles. “That’s the look I wanted. The gay panic. So fucking cute.”

Gay? She wasn’t...! Wait, no - maybe she was, now. Why else would she be so utterly thunderstruck by the sight of her friend, this girl she’d known for two years and had a platonic fembot-with-benefits relationship? This little minx had clearly done something to her - this ‘HiG subroutine’ that’d been hidden from her must have overridden her sexuality, rewriting her code, altering her personality, modifying her desires to suit Sabrina’s own purposes... It now seemed ridiculous that she’d ever been able to look at the sexy shortstack without foaming at the mouth... Images of her luscious body - her pert boobs, her incredible ass, her slick, tender pussy - were flickering through Selena’s computerised brain, even though her gaze was still fixed on those big, almost cartoonishly-round, smouldering eyes that seemed to stare right into her digital soul...

Help, I’m gay, she thought. A second later, she realised what the ‘HiG’ must stand for. The corners of her mouth twitched, but she was too taken aback by her newfound feelings to laugh at the silly acronym.

Was she, though? Did her nascent homosexuality apply only to Sabrina, or to all women? Did Sabby create this subroutine merely to give Selena a giant girl crush specifically on her, or to make her a flustered horny mess around any girl she came across? Her eyes darted across to the other couch - and the pounding of her cardiac pump at the sight of the nude couple, watching her with their hands between each other’s legs, told her she was, indeed, hella gay.

She could feel her circuits heating up as she remembered these women - these Goddesses - bossing her around, using her for their pleasure... touching her, kissing her... doing things with her that she couldn’t quite dare to put into words all of a sudden, even inside her own mind... She’d done them quite happily (and quite emotionlessly, when she’d just been S3), yet now she could hardly bear thinking about them lest she combust...

“You good, babe?” Sabrina asked, her wicked grin broadening.

“Aff-affirmative,” Selena whimpered, her cheeks going twice as red as before as she realised she was still talking like a robot. So humiliating, stuck speaking like that in front of all these pretty girls... Then again, she knew they had disabled her human speech, because they wanted her to embarrass herself in front of them. What had made her vaguely blushy a few minutes before, was now utterly mortifying...

Finally releasing her chin, Sabby slid down the chair and landed in the seat next to her, her legs still akimbo. The fembot forced herself not to peek down between them. “You seem a little, I dunno... unresponsive, all of a sudden,” she noted wryly. “CPU running a lil slow?”

“The - um - this - this unit -”

Whatever sentence she was composing in her CPU fizzled out into meaningless code as Sabrina laid a hand on her cobalt thigh. “Aww, poor thing,” she sniggered. “Maybe I should go easier on you, so you don’t totally overheat. Then again, you are supposed to be a highly advanced android - cutting-edge technology. You’re always talking about what a sophisticated machine you are... so you oughta work properly!” As the android stared at her with wide eyes, she tutted. “What’s the matter?” She reached out and rapped her knuckles twice on Selena’s forehead. “Error? File not found?”

The robot girl had to remind herself to breathe. (She needed to breathe the same as any human - it was how she’d been built.)

“OK, Walking Smartphone,” Sabrina smirked. “I’ve heard that lately you’ve been masturbating more than before, mostly for Andrew’s enjoyment. I’m gonna need to see exactly how you do that. S3, I want Program:Selena to demonstrate the way she jills off for Andrew, and to narrate what she’s doing and why.”

“Confirmed.”

Oh, so this was what a total systems failure must feel like.

Unable to stop herself, Selena lifted her ass slightly off the couch cushion and tugged her fuckhole zip along, until her nether regions were exposed. “This unit usually begins its masturbatory routine by stimulating its labia and clitoris,” she said tremulously, the words falling out of her mouth without any conscious effort, as one hand slipped between her legs and started to stroke her slit. “It will also expose its breasts for User:Andrew’s additional enjoyment,” she continued, her other hand slipping the nanosuit off her shoulders and rolling it down a little, so that when she then bared her boobs, they would remain that way, the polyester flaps staying down rather than falling back into place.

“Mmmm,” Sabby sighed, lying back against the armrest and beginning to caress her own cunt as she watched and listened. Across the room, Dani and Jelly were continuing to edge each other to the sight of the flustered fembot, side by side with their legs overlapping and entwining like snakes.

“User:Andrew will often command this unit to pause during masturbation, and it will freeze in place until he instructs it to resume. Once it has produced sufficient synthetic lubricant, this unit then penetrates both its vagina and anus.” She slipped her left index finger into her pussy, while her right hand slide beneath her and buried its middle finger up to the knuckle in her butthole. The two invading digits began to seesaw back and forth.

“Ohh, I fuckin’ love that...”

“As this unit c-continues to m-masturbate, it will use dirty talk to further arouse User:Andrew,” she whimpered helplessly. “Examples include, ‘This unit was made for your pleasure’. ‘This unit is your willing sex toy’. ‘This unit is your android slut’. ‘This unit is your anal whore’. ‘This unit was built to serve you’. ‘This unit exists to be fucked by you’. ‘This unit wants your big, hard cock in its tight little asshole’...”

“Does he ever fuck you while you’re doing this?” Sabby blurted, gazing between her own spread legs at the fembot frantically fucking herself. “I gotta imagine it’d be difficult for him to resist...”

“Affirmative, in approximately 20% of sessions. User:Andrew usually watches, but in some instances he will have this unit perform oral sex upon him while it continues to masturbate. He would then climax in this unit’s mouth, on its face, or on its chest.”

“Nngh... D-don’t finish yet, but tell me h-how these sessions end...”

“This unit masturbates until User:Andrew commands it to stop, which usually occurs after he has achieved orgasm. Whether or not this unit has also achieved orgasm is irr-irrelevant.” Ironically, Selena felt herself cum even as she said that, stumbling over a word but unable to stop speaking altogether as she clenched around her thrusting fingers. “User:Andrew will then often command this unit to clean his penis, and any other part of him on which he has ejaculated, with its tongue. The session usually concludes with User:Andrew showering with this unit and thoroughly washing its skin covering.”

Panting, Sabby pulled her hand away from her pussy, grinning broadly. “Y’know, oral sounds like a great idea right now. I know from experience what a talented tongue you’ve got, cutie bot...”

Luckily, with her narration concluded, Selena didn’t need to answer that with words. Her only response was a verbal keysmash.

“S3, come eat me out. Keep on fucking yourself til I say otherwise.”

“Confirmed.”

Her fingers still probing relentlessly, Selena swivelled to her left and lowered her face towards Sabby’s crotch, the smell of her filling the robot’s olfactory sensors. Her internal fans whirring at almost top speed, she silently prayed her head wouldn’t explode between the blonde’s legs.
