2B's Introduction to Human Mating Practices (Patreon)

And it's time for another batch of mini stories! Starting off with a character I'm sure most, if not all of you have seen before! This story does contain a bit of futa, just in case that's not your cup of tea!

Despite her usual stoicism 2B couldn't help letting out a soft moan as a long, throbbing human cock slid into her recently added vagina. Although she'd been told to expect pleasure while the addition was being made the amount and degree of pleasure she was experiencing as her inner walls stretched open was quite a lot more than she expected. Enough to send shudders coursing through her body and put an ever so slightly crimson flush into her cheeks. Upon feeling the man behind her's body collide with her rump she felt another, even more high pitched gasp escape her lips. The sensation of having something, anything, so deep within her was strange enough on it's own but the toe curling satisfaction combined with the constant waves radiating outwards from the depths of her newly added sex proved more than enough to send her knees pressing together and her back arching downwards as she bent over to clutch the railing she was standing in front of. Hearing the satisfied and wholly exuberant groan of the man who'd just entered her for the first time provided another little dose of excitement. Knowing how much he was enjoying himself already was second only to feeling it as his member pulsed like crazy within the depths of her slit.Able to feel and enjoy every dollop of thick, creamy fluid leaking from his gland as it remained embedded inside her 2B had little trouble understanding why humans placed so much value on the sexual act she'd been tasked with performing. If it felt anywhere as pleasurable for them as it did for her she understood completely.

And of course that understand rather quickly turned into some sort of craving as she felt her partner's hands grab her waist and heard his feet sliding further apart to help help with the soon to come thrusting. Flushed with an uncharacteristic eagerness she  did her best to straighten and turn towards the woman standing nearby waiting for her chance to join in. She too was sporting a rather impressive set of apparently not solely male sex organs and while the android the two had been given was somewhat uncertain of what could be gained by using her mouth on a human member she had little trouble accepting the idea for the purposes of aiding her creators. Fortunately when the woman approached and lifted her twitching length to 2B's mouth she had little trouble understanding the appeal of what she'd been asked to do. Barely two seconds after the taste of that bitter, clear fluid oozing from the woman's tip fallen on her tongue another wild shudder coursed through the formerly combat unit's body. Her wide open mouth closed down with a little more conviction and her tongue reached out to do more than simply taste. The woman before her groaned in satisfaction and wasted little time sliding her shaft down into the depths of the android's throat with a gentle yet firm pace that did a wonderful job of heightening the excitement all three of them felt. Both humans were quick to unleash satisfied groans as their members throbbed like crazy within the gorgeously tight android they were fucking while that very same android shivered and trembled with an ever growing delight as her body rapidly adjusted to the wonderful experience that was sexual intercourse. All the information she'd been given beforehand truly didn't do it justice and though she couldn't express as much in words she was beyond eager for them to begin moving properly.

Fortunately her wait was counted in milliseconds as neither of the humans inside her could remain inactive for very long. While 2B was still adjusting to the unique sensation of having a long. Twitching member embedded in her throat and disgorging copious amounts of fluid into her body the man inside her pussy pulled out with a shuddering moan. The sensation of his cock retreating from her sex proved to be somehow even more enjoyable than the initial penetration and she was quite taken with how his length felt rubbing against and stimulating her inner walls. Her body naturally tightened around him as he departed and only further tightened when he suddenly returned a moment later. The forceful impact of his hips against her buttocks send 2B lurching forward just as the woman enjoying her mouth was pulling out as well. Both android and human moaned in delight at the sensation, even if the male had a degree more passion in his voice as he watched her incredibly round, incredibly tight ass bounce ripple and bounce from his thrust. The noticeable swelling of his cock inside her was every bit as wonderful as she thought it would be an a perfect accompaniment to the unique yet undeniably fantastic sensation of another member sliding along the walls of her throat. The ensuing smack of flesh against flesh when the woman thrusted forward proved exactly as delicious as the one her male counterpart had given a split second before. Perhaps a little moreso as 2B felt and enjoyed the slightly wet smack of her female partner's testicles against her chin. She had little idea why she enjoyed that particular sensation or why it should matter in the least but thankfully comprehension wasn't a requirement for pleasure and her body was more than equipped to experience the latter. An ability she made full use of as the humans on either side of her wasted little time repeating the movements that'd brought them all so much pleasure and even quickening their pace as they did so. Neither had any trouble or any reservation building into a steady, passionate rhythm as quickly as they could.

Within a couple minutes 2B found herself bouncing back and forth between the humans on either side of her as they settled into a perfectly symbiotic give and take that always saw one of them thrusting inside her while the other pulled out.The wonderful and uniquely joyous effect this had on the android's body couldn't be overstated, nor could it be fully understood even as she moaned in delight with every last movement. Copious amounts of lubrication leaked from her sex and mouth as both were used with more and more gusto whole the radiating waves of pleasure cascading through her seemed to grow in direct proportion to the speed and strength of the humans using her body. But even that wasn't enough to really satisfy her and she soon started actively pushing herself onto whichever cock was thrusting inside her at any given moment, her fantastic ass bouncing more than ever while her equally beautiful face flushed a deep crimson. Upon seeing and feeling just how eager she really was her human partners wasted little time vastly increasing their pace, both male and female quickly building into the sort of wild frenzy their android lover had been told about beforehand. Soon the otherwise quite and still night was filled with the frenetic slap of colliding flesh and desperately exuberant moans as all three of them settled into the madcap pace that would eventually carry them into the climaxes they were so hungrily seeking out. Though it did take another few minutes before they were truly at their limit that time felt almost painfully short as the endlessly cascading pleasure and rising anticipation overshadowed any semblance of reality beyond their bodies. By the time both humans were panting and gasping in a very telltale manner the android they were about to pump full of spunk was in much the same state of mind and body. Her lewdly passionately gurgles and sloppily exuberant moans were exactly what the male and female thrusting inside of her needed. With near identical groans the two buried their shafts within 2B and unleashed massive fonts of gooey semen directly into her body. The warmth and thickness of their fluids alongside the thrilling method of delivery sent her into paroxysms of ecstasy shortly after and her already tight holes milked the pair dry within seconds as her specially modified form took full advantage of the changes that'd been made. Every last drop they had to give was sucked from their loins by her mouth and pussy while ecstasy surged through the three of them and their delight echoed across the dead city around them. For nearly a full, unbroken minute that pleasure was their world and even once it'd begun to fade the echoes of it remained for much longer. Undoubtedly helped by the continued rigidity of the two humans and their refusal to pull out entirely.

“Can we keep going?” The man asked. 2B eagerly nodded and the woman gasped out a quick thank you. But in truth the android was the one who should be thanking them. Her existence had grown exponentially in such a short time and she couldn't wait to see how much more it could develop with the help of her companions!
