A cyborg connection

Something about the look in Jessie's eyes gave you shivers, as she stared at you in a way that felt so strange, like she'd changed gears from her happy-go-lucky work mode to this sexy vixen, clad in nothing but her panties as her arms, both regular and the large Silverback set, stretched out from her shoulders. You were enthralled by her majestic body, generous breasts, and generous lady who would share said breasts with you. Technically still, she was sharing with Marian, but Marian seemed only ever along for the ride. You thought about how to convince Marian to get even more onboard with everything instead of simply being accepting of how this night might go, with her simply letting you control.

As you think back to earlier sessions in the shower chamber, you smiled, realizing your way in. Marian may not be very interested in women, but she did seem to be interested in the sensations she felt through the Tarantula machine! The car-wash brushes seemed to send her into an unusual orgasmic state each time. Maybe a pair of Silverback hands could help there... Before Marian could say anything, you seized control again. "How about... skin on skin, metal on metal. Could you try massaging my Tarantula unit with those hands?"

"Oh, now there's a thought!" Jessie said, as she leaned forward, embracing you and Marian in another kiss. This time, Marian didn't tense up, you didn't feel resistance, but she wasn't yet fully relaxed while Jessie worked on the removal of your shirt, wanting to free your less impressive but still sizable pair from the confines of the fabric. Her hands felt wonderful touching Marian's body, gliding along with just a little bit of a rough, calloused feel to them from Jessie's experiences working in construction. You shivered upon her touch as your shirt was lost, before bare chests collided in the second embrace.

The moment that won Marian over, however, was when Jessie leaned the upper body back, resting over the hump of the submodule unit, as her Silverback hands reached up and began to glide and caress over the main module. Suddenly, these moans were not your own! You let up on control slightly, out of curiosity, only to see that Marian seemed to grip even tighter to Jessie in the embrace, hoping for even more contact with those massive robotic hands on her equally massive robotic body. It was heavenly, but in a bizarre, alien way. In some way that the body understood was not correct for a typical human. But a wrong heaven is still a heaven, and that's where everyone was transported to.

Suddenly, Marian couldn't get enough of Jessie's touch! She needed plenty of encouragement with kissing and involving the hands, which you readily provided, keeping lips locked and hands roaming from Jessie's back to the sides of her breasts spilling out around you, down to her hips and gripping at her ass to hold her even closer. The moaning, the squeaking, the random blurted words, those usually came from Marian's side as the massage of the Silverback hands on her body sent shivers into her whole self. Marian seemed wholly captivated by the idea of the machine parts interacting, not really caring who they were attached to, she seemed almost disconnected from the human side of things entirely at some points!

You found that all fascinating, but admittedly you didn't want to think much on it for now. There wasn't much else to ponder, as when some exhaust vents opened up on either side of the module--a sign that the Tarantula frame was heating up along side the organic body--fingers from the Silverback arms plunged right into those! The sensation even caught you firmly off-guard--it was like you were being penetrated in stereo, this feeling of something sliding into you in strange and unusual ways. Marian's neural plasticity had somehow adapted her mind to treat those exhaust ports much like the same sensations she would experience from her organic pussy, but absent that, they seemed to make fine stand-ins. Better than fine... you were putty in Jessie's very capable hands!

Jessie realized the effect all of that had on you, grinning as she lifted herself up a bit more for more leverage, as the exhaust ports were fairly distant from the human part of the whole configuration. As she lifted, her breasts seemed to rest upon your face, and you cradled her ass in your arms while she played with whatever manufactured orifice she could find, gauging the effectiveness of her touch by the yelps Marian made with her mouth into the squishy breast flesh resting on her cheeks! Marian had disassociated entirely with her organic body by that point, where you didn't have to take control over most of her, you were simply handed the keys to her organic side while she focused on squirming and shaking those robotic legs in response to all the attention. Jessie had somehow managed to find ways to touch Marian that thrilled her even more than how Jessie herself thrilled you!

"What kinda module you got attached to you right now?" Jessie asked as she huffed a bit, especially as you had started taking the liberty of licking at one of her nipples and running a finger along her slit through her panties, spurring her onward. Trooper that she was, though, she seemed to keep it together throughout your own teasing, although the occasional whining moan helped indicate you were doing a good job. "I don't see a label on it."

"It's just an extra recharge module," you whisper, as you weren't sure Marian was even listening to the conversation now, having given up on her organic body for a better bliss elsewhere. "It can feel weird to have nothing installed in the off-hours, so sometimes I'll use one for familiarity's sake."

Ideas seemed to populate Jessie's mind, as she lets up from you briefly, both sets of hand removing themselves from their touch upon you as she sits upright for a moment, examining your existence as a hybrid human-machine being. The lack of attention pulled Marian back to reality, as she glanced up at the near-naked Jessie. "You stopped, but it was so good, why'd you stop?" She had been so engaged with the hands on her metallic frame that Marian was ready to beg for more.

Instead of answering that question, Jessie hopped off the counter she had sat upon, strolling around back, running three hands--one organic, two mechanical--along the side of the Tarantula frame as she did. She went to the very back, where you lost sight of her, but you felt her stand on the small platform in the back that stepped up to the module. Jessie seemed to mumble something to herself, you couldn't hear her, but you and Marian waited patiently to see what she might do.

The fact that Marian was so pleasurably attached to the Tarantula unit made everything Jessie did an incredible blissful experience, and when she opened up the hatch in the back to the internal recharge chamber, this was no different! Her Silverback hands started to probe inside, as Marian gasped at the intrusion--Jessie was climbing inside! "Oh, oh god..!" Marian simply exclaimed as she had to brace all her legs and both hands on wherever they could find purchase, feeling this human sized figure pushing into her body in such a new, strange way. You knew this was entirely unusual for someone to find these units so pleasurable like this, at least at this degree, but that seemed like it would only work out to Marian's benefit in the long run if work was constantly bringing her to some sort of synthetic climax state!

The recharge module was a hollow unit, with battery packs lining the wall within, and charging stations with electrical rods attached to long wires stored throughout. On long deployments with multiple units with no easy access to their own place to recharge, the Tarantula unit was capable of allowing one person inside the module to recharge on the fast charging platform, or up to eight of the wired rods could extend out to plug into other Yabusa machines and keep them topped up on energy for a few days.

What became clear very quickly as Jessie closed the hatch, locking herself fully inside Marian's body in a technical sense, was that Jessie realized that playing up the bizarreness of the sensations seemed to thrill Marian, which in turn thrilled you, though Jessie didn't know the difference between the two minds, still operating like there was only one of you in this form. "I can't believe it, she's all the way in," Marian huffed, her whole body rising and falling with her heavy breaths in anticipation for whatever Jessie was going to do.

Marian moaned, shuddered, thrashed about as she felt those massive hands again, on the inner walls of her module. The exhaust ports had felt like vaginal penetration earlier, but this was some sort of step beyond, to this massive realm of sensation that perhaps humans weren't ever meant to know! Marian screamed loudly, but only because she was racked with pleasure caused by all this unexpected touching, this sensation of this whole human body stored within this module feeling around, throwing Marian's brain for a loop. She might not even be able to do her job normally if the intensity of this interaction wasn't dulled later on, but you made a note to mention that some other time. You'd experienced clitoral stimulation with one of the previous trainees who would relieve herself at night, but this was as if the main module behaved like an entire clit with something stimulating it from within constantly, rubbing an extremely large surface and overloading poor Marian's mind with unrivaled pleasure!

You had a tough time keeping a grip on reality yourself, eventually feeling something new happening within the recharge chamber. You and Marian had tactile senses of everything within so you would know when a recharge rod was in use, for example. You both became very aware of it, as you felt Jessie pull one of the rods out of their storage slots, and then it felt like she began to push it in somewhere... and then a second one, somewhere else! You and Marian traded moans throughout that process, as you realized that the warmth and slickness that enveloped those rods meant she must be pushing them inside her body, possibly her pussy and mouth, though you couldn't tell. The thrill that came over you was mostly that Jessie was using a part of your and Marian's body to masturbate, while simultaneously using those massive arms of hers to continue to massage from within!

The orgasmic rushes were fast and frequent. Marian's organic half was red-hot, sweating profusely for the hour that she endured stimulation beyond what any one human seemed capable of. Her mechanical half was flashing all kinds of warning lights, bathing the room in red hues from the various panels and ports that seemed to overheat or were in the process of malfunctioning due to strange signal paths routing through both bodies, causing the Tarantula unit to shiver and shake uncontrollably in a few places. Jessie opened the back hatch after the action died down, and she stumbled out, equally out of breath and sweaty, as she practically crawled back around front and propped herself up on her Silverback arms to deliver a final sloppy kiss.

"Amazin'," was all she could get out, before she--and you--collapsed in exhaustion.

By the time morning rolled around, Jessie had vanished. The Tarantula had run through various self-diagnostics and corrected some of the anomalous signals, and with much of the overheated unit having time to cool off, everything felt back to normal in the morning--save for your sticky skin and messy hair. You waited for Marian to get to her senses, though, letting her dictate the pace of the morning as she worked through the experiences of last night.

"I... don't really know how to describe any of that stuff from last night," she finally said out of the blue in the middle of her breakfast. "You and Jessie kissing was nice, I guess, but how my body felt when she was all the way in and feeling around... I think I might have to sign up for the Tarantula project long-term to keep doing that. How could I go back to anything else? I don't even need the human part of me, just keep me in the Tarantula and that's all I'll ever need..."

You couldn't argue with her there. She seemed naturally attuned to how the machine felt. It was like nothing you'd experienced with any of the other trainees, with any of the other machines you'd trained with them on. Something was particularly special about the way Marian had been able to assimilate the Tarantula body with her own.

You spoke calmly, again as Marian's trainer rather than a participant in the activities from last night. "Well, we do have to finish one more day, and then I'll provide my evaluation of your fitness to operate a Tarantula to Terraflex, Depending on my recommendations, they might keep you temporarily assigned to the Tarantula pilot program, they might issue you a long-term unit, or they might move you into another position with a different Yabusa machine."

"No!" Marian suddenly exclaimed, surprising you both enough that you took control just so she didn't slam her fist down and knock breakfast foods all over the floor. "Nhh, uh, I'm sorry. There has to be something you can do to help me there. I'd let you use my body to spend time with Jessie, right, that's bonus points? I'd do whatever you wanted, Module 6, just please... whatever you write, it has to get me a long-term Tarantula module. This can't be my last time doing that!"

You nodded, slightly. "Noted, Mari." While you didn't feel like you had to be extorted to write Marian a glowing review, as she was going to get one anyway given her natural abilities and quick learning throughout the training exercises, the promise of getting any favor in exchange for the writeup was something worth keeping in the back pocket on this last day.
