“New device pairing complete. Accessing new device. Enabling new device. Oh fuck, that feels weird!”

Program:Selena was sitting on the couch with her legs spread, gazing down in awe at the new attachment hanging from her groin. The instant it had been fully enabled, she could feel every inch of it - its weight and thickness, the artificial blood pumping through it, the sensitive surface... She tried to make it move without touching it, and both saw and felt it twitch, sending shivers of arousal through the rest of her.

Reaching down, she ran her fingertips over the foreskin. “Oooh, god,” she gasped, “th-that’s... I...” For once in her life, the robot girl was lost for words. For someone who was built and programmed to be a cisgender, heterosexual woman, the novelty of having a penis was mind-blowing - and not a little exciting. A wide, wild smile spread across her face as she continued to stroke and stimulate the sensors in the synthetic skin.

“How does that feel?” User:Andrew asked. He was watching from the armchair, literally on the edge of his seat.

“It’s - it’s like my pussy went from an innie to an outie,” she giggled, to which he barked with laughter.

True to his word, Andrew had thought more about the strap-ons for sale at the convention, and had gone back to buy one with this specific purpose in mind. The phallus he had purchased was made to be fairly realistic - it was a reasonable size, thick veins decorating its surface. Its pale pink colour didn’t quite match her own olive skin tone, but that didn’t matter as it was an external device. USBs didn’t have to match a computer’s colour scheme to be plugged into them.

Although it was ostensibly a regular silicone dildo, it hadn’t taken much to convince S3 that it was in fact a mechanised accessory, containing wires and circuits just as the android did. After buckling it into place around Selena’s waist, settling the base in the gap opened up by her fuckhole zip, it was a simple matter to establish a link to the prosthesis through the Wi-Fi. And just like that, she had a cock and balls, which felt just as real to her digital mind as her usual, now concealed genitalia.

The balls! She’d forgotten about those. Sliding her hand beneath her shaft, she began to caress her testes, squirming in her seat. They felt ticklish, but not quite in the same way as other parts of her did (when her sensitivity had been dialled up to that effect, which only happened when Andrew wanted to torture her). It was a kind of erotic ticklishness that felt different to stroking her foreskin - or her labia, for that matter. It was odd, but kinda fun.

After fondling her nuts for a little while longer, Selena returned her attention to her dick, shooting a rueful grin at her boyfriend. “It’s really hard to stop playing with it,” she admitted.

“Welcome to my world,” he replied wryly. “And to be fair, I expected as much. Take your time, get used to how it feels...”

“Don’t think I’ll ever get used to it,” she muttered. “This is... I mean, my sexuality’s been fucked with this week, and that’s one thing. But my gender, and my body... This is, it’s unprecedented.”

“It’s OK though, isn’t it?” he asked seriously.

“Oh, of course,” she assured him. “You know you can do pretty much whatever you want with me, unless I tell you otherwise. Especially if it’s fun. Which this definitely is!”

Although she still thought of herself as a cisgender woman, she felt no dysphoria from having a dick - mostly because she knew she actually wasn’t a cisgender woman, merely a machine built to resemble one. It was her User’s prerogative to instal any new parts in her that he wanted, even if they didn’t necessarily fit her external design, as long as they didn’t damage her or impair her functionality. No, having a cock and balls was simply different, and uncanny, and thrilling. Not to mention, hot.

The implications with regards to her boyfriend were intriguing, too. Like her, he’d claimed to be straight since they’d known each other, but the fact that he’d now equipped his fembot with male genitalia fascinated her. And he was watching her play with it pretty intently, his hand between his own legs... Of course, he could be attracted to girls with dicks and still be heterosexual. But she also could’ve sworn she’d seen him checking Milo out at least once this week... Perhaps he wasn’t as straight as he said, or even realised - or perhaps he just found gender play really hot. She’d be interested to find out.

“Sooo, you got any ideas on what you want me to do with this thing?” she grinned, nodding at her new component. “Or you want me to keep on familiarising myself with it?” When he paused for a long moment, she continued, “We could just sit here jacking off together. Like usual, but with an extra dick.”

“I could go for some mutual masturbation,” Andrew nodded, smirking. “Very romantic.”

She spluttered with laughter, even as she jerked her hips and slid her throbbing meat back and forth in her grasp. Fuck, that felt amazing. And if her own touch was this good, she couldn’t wait to feel what it’d be like in someone else’s hand. Or mouth. Or pussy...

She was never usually this randy! Sex and masturbation had never really done much for her - it was well established that she got off more from acts of service, from being an obedient robot. But now that she had a dick, she was suddenly desperately horny. She wondered if the mere act of connecting with this cock had altered her programming - or whether Andrew had covertly dialled up her sex drive. Whatever the explanation, she was absolutely rock hard right now (even though the rubbery phallus was still pliant and flexible to the touch). And she was having some pretty vivid fantasies about testing out her new attachment, with Alyssa, or Sabby, or Jelly, or Hailee...

She’d been commanded to fuck the other girls multiple times that week, and her mouth, fingers and pussy had definitely been up to the task - but she couldn’t wait to try ploughing her penis into them. She nearly edged just imagining how it would feel, to have them clench around her cock as she thrust inside them, or to lick and suck her shaft as she fucked their faces...

“W-would you give me a blowjob?” she stammered as she rubbed her tip in circles, twirling her cock around beneath her finger. Andrew seemed to hesitate, so she added, “I mean, not to put too fine a point on it, but I’ve sucked you off a lot!”

“Very true,” he smiled. “I should definitely reciprocate. But I’ve never done it before, and I would want you to get your first blowjob from someone with more experience.” Pulling his hand out of his shorts, he stood up and strolled past the couch, towards the door that led through to the kitchen. “Gimme a minute, babe,” he called back over his shoulder. The fembot groaned with flustered frustration as she kept fiddling with her dick, sliding her hand back and forth along its length and shivering at the stimulation to its sensors.

Her User returned moments later, and he wasn’t alone. “Heard you needed help from an expert,” Hailee said, dropping onto all fours and crawling between Selena’s spread legs with a coquettish smile.

“If you’re willing to give it,” Selena sighed, still jerking off even as her host’s head approached her crotch.

“Of course! What else are fucktoy friends for?”

The robot lurched backwards and let out a strangled cry as Hailee slowly drew its tongue along the underside of its dick. Then it wrapped its lips around the head and beginning to slide along the shaft, just as her hand had been moments ago - but so much better. As thrilling as her own touch had been, it was nothing compared to the feeling of a warm, wet hole enclosing her cock.

One of her hands seized a couch cushion in a grip of steel. The other clutched at the hair on the back of Hailee’s head, at the mercy of its mouth as it explored her throbbing phallus. Her hips jerked manically as the advanced android effectively lost all self-control and surrendered to the unorthodox sensations and the unprecedented pleasure, abandoning her efforts to restrain herself and let Hailee control and coordinate the oral sex, in favour of frantically fucking her friend’s face. It made no attempt to stop her, allowing her to ram her robot dick down its well-practiced throat.

It wasn’t long before Selena felt herself climax, the sensation of spurting entirely simulated, but no less erotic for it. Although the external device lacked the ability even to produce the lubricant she secreted from her artificial pussy, it felt to her very much like she really had just filled Hailee’s gullet with her cum. She gazed down at her friend, her pulsating protrusion still buried in its mouth. The mouth she’d just supposedly soiled with her seed, claimed as her cocksleeve, marked as her cum bucket. I really get why guys like this so much, she reflected with a dazed smile.

Although the blowjob had reached a fairly clear conclusion, Hailee stayed where it was, continuing to warm the automaton’s attachment with its mouth, as she gratefully cradled the back of its head with one hand. Across the room, a panting Andrew climbed to his feet, naked from the waist down. He’d returned to the armchair to watch his girlfriend getting sucked off, and had apparently orgasmed at roughly the same time as her, splattering cum on his thigh and the white leather of his seat. “Sorry, Hails, I didn’t mean to make a mess,” he grimaced. “I was gonna go over there and cum in Selena’s mouth while she came in yours... but my legs kinda failed me!”

Hailee chuckled around Selena’s cock, and she shivered as its mouth vibrated against her foreskin. After a quick entreating glance up at the android, who nodded and let go of its hair, it slipped off her shaft and turned to face her boyfriend. “No worries, dude! I can come clean that up for you, if you like. Unless Selena’d rather do it...?”

“I would, but I think my legs have stopped working now,” she laughed weakly. (A quick systems diagnostic told her that her legs were still functional, but she was low on energy and would need a few minutes to recharge.)

“Then let the host take care of everything, don’t you worry,” Hailee said with a grin, and then crawled across to Andrew’s abandoned armchair and began to clean up his mess with its tongue.

Pulling his shorts back up, Andrew came over to join Selena, perching on the arm of the couch. (Her legs were still spread widely, leaving little room for him to sit on the seat next to her.) “You looked like you really enjoyed that,” he smirked.

“I really did,” she exclaimed, beaming up at him. “This was such a good idea. Thank you so much, User:Andrew.” He smiled fondly back at her, reaching out to stroke her hair as she returned her gaze to her new equipment, hanging in mid-air like a wobbly spearhead. Cupping her balls with one hand, she just sat there and continued to enjoy the feeling of her manhood (or womanhood, she supposed) in silence, while her boyfriend gave her headpats.

A thought abruptly occurred to her, and she arched an eyebrow. “I wanna try something.”

“OK...?” her boyfriend asked hesitantly, a curious smile spreading across his face. “Go ahead.”

Grinning eagerly, she reached behind her and unbuckled the strap-on’s harness. Then she lifted her dick away from her groin, its straps trailing along with it. She sighed elatedly as she felt it throb in her hands. Although it was no longer situated on her crotch, their connection was unbroken. She was still linked to it through the Wi-Fi, and could still feel everything it felt.

However, she could now also feel her pussy - its sensations had been disabled when it had been covered with the prosthetic phallus, but now that it’d been removed from its position, her original genitalia was reactivated. She was very aware of how wet it was - it had clearly been leaking lubricant, probably the entire time she’d been masturbating with the cock (or, at the very least, when she’d climaxed). It was odd, being able to feel both sets of genitals at once, especially since her body was still receiving inputs from them as if they were located in the same place.

All this was as expected, though. She was fully aware of her own body, her own systems, and knew what to expect if she detached her dick without disconnecting from it. That wasn’t what she’d wanted to try.

Taking a deep breath, she turned her cock towards her crotch, and slid it inside herself.

“Ohhhh, fuck,” she cried, overcome by the feeling of a slick pussy - her slick pussy - enveloping her dick, combined, of course, with the feeling of a dick entering her pussy. Experiencing just one side of the equation had been enjoyable enough in the past, but it was nothing compared to the feeling of both. She was in heaven. (Or a virtual facsimile thereof.)

She gawped up at her User, who seemed similarly thunderstruck. “How’s that feel?” he asked incredulously.

“Beyond strange, and super fucking hot,” she squeaked.

“You planning to fuck yourself from both sides now?” he chuckled.

“Ohhhh... tempting prospect,” she sighed. “I also like the idea of just, I dunno... warming my cock for a bit. Just enjoying having it buried in a pussy, and enjoying having something filling my pussy, at the same time. But I do wanna get off, too.” She smiled placidly up at him. “Your call.”

“Cockwarm for a while, then maybe masturbate again later,” he told her.

“Confirmed,” she sniggered. Reaching below her butt, she found her zip and tugged it up, sealing her full fuckhole away. Andrew offered her a hand, which she accepted, getting unsteadily to her feet. She felt the dildo move inside her, and at the same time felt her dick’s surroundings shift. Motherboard of God, that felt bizarre.

“Gotta be honest, this worries me a little,” her User remarked, in a clearly joking tone. “Now you’ve got your own penis, and you can even use it to have sex with yourself, what do you need me for...?”

“Telling me what to do,” she grinned. “Coming up with fun things to do - this was your idea in the first place, after all! Using me for your pleasure...”

“Hey, I could always fuck your ass while you fuck your pussy,” he mused with a lewd grin. “Or vice versa!”

“Well, exactly. The possibilities are endless.” She gave him a look of adoration. “At any rate, your pleasure is my purpose. All this is to entertain and arouse you. It’s not worth me getting off if you’re not there to see it. This unit exists for your enjoyment.”

She was delighted to see him smile lovingly, and feel him squeeze her hand, as they strolled through the house to find their other play partners. Her dick bobbed about inside her as they walked, sending quivers through her mechanical body. She meant every word she’d said, of course. Although she might’ve gotten a little lost in her own ecstasy that day, it was all still ultimately for User:Andrew’s benefit. Her truest, greatest pleasure was to serve and satisfy him.

But playing with her new penis had quickly become a close second!
