Beep. Beep. Beep. Beep-beep. Beep-beep. Beep-beep-beep-beep-beepbeepbeepbeepbeep!

“Hey!” shouted Miko. “I think I found it.” The energon detector was going crazy in her hands. After several hours of inactivity, it was a blessing to see its LED screen light up and flash repeatedly. It was Miko’s job to hold onto it during her and Arcee’s trip through the mountains. She’d brought a forest green two-piece jumpsuit for the journey. A large satchel hung from her shoulder. Her pink-highlighted black hair was tied into a long ponytail, different from her usual pair of pigtails. It wasn’t her preferred outfit, but anything nicer wouldn’t fit in the rugged, forested mountains.

She’d ridden Arcee all the way up here. The Autobot was still in her motorcycle form, ready to drive Miko further up the trail if she needed to. The sudden and rapid beeping of the energon detector meant that wasn’t necessary. Wrrr-rrr-rrr-rrr! The parts and panels of the motorcycle separated and began whirring into a tall, feminine robot. Upon completion she was a buxom machine replete with a womanly shape and face. Highlighting the exotic blue of her paint color was a phantom black that covered the rest of her. “Find it?” she asked in a digitalized timbre.

Miko’s head was bent forward over the detector. She took slow steps forward and in varying directions, listening to the beeps grow louder and faster until the pauses between became indistinguishable. “Yeah, I think I did,” she said proudly. The detector went into her back pocket before she pointed straight down at the ground. “The deposit’s got to be right here. The mother lode can’t be too far away.”

“Then we’ll start right here.” Arcee strode up to where Miko stood, her pneumatic joints hissing with every step. “Step aside.” Miko moved back several paces. Arcee fell to one knee and laid a hand on the ground. Thrumming beneath the surface was the familiar tingle of energon. It triggered a Pavlovian response in her core, a sort of thirst like someone on a hot day seeing a glass of ice water. Yup. It’s down there alright. Arcee stood up and got into a stance with one foot behind her. One hand balled into a fist, cocked up next to her head, then slammed into the Earth full force.

WHAM!

An eruption of dirt and rock. The ground cracked and shook around her arm, now buried to the bicep. A fog of dust sprouted from the ground all around them then slowly drifted away. Miko had to shield her face from the debris that flew towards her and bounced off her jumpsuit. She waved her hand in front of her face and coughed. “Koff-koff. Geez, was that really necessary?”

Arcee pulled her fist out of the ground. Dirt and shattered rock fell from it as she stood upright. “If we want to get in the cave, yes. It’s underneath a thick layer of bedrock. You can’t just dig through that.”

“Whatever. I just hope the cave’s not too small and you won’t have to do that again.”

Arcee gave her a coy look. “What? Think I’m above heavy labor? I’ve been doing this for years since I’ve come to Earth.”

“I know you have. It’s just loud as hell and I don’t like it. It’s scary,” Miko said as she approached the fist-sized crater in the ground.

“You’ve been through worse over the years.”

“Yeah, doesn’t mean I enjoy doing this stuff.” Miko knelt next to the crater and drew a flashlight from her bag. It came on with a click and filled the hole with a beam of light. Through the fractured bedrock she could see a separate floor further below with several feet between. “Oh yeah. That’s a cave alright.”

“Think you can find the energon down there?” Arcee asked.

Miko stood up and sighed. “Can’t be that hard, can it?”

“Just yell if you need help. I’ll get you out in an instant.”

Miko scoffed. “I’ll be fine.” She made a give me gesture with her hands. “Come lower me down.” Arcee knelt back down and craned her arm over the hole in the ground. There was a ker-shunk sound when her hand retracted into her arm and was replaced by a grappling hook on a cable. It unreeled from the wrist slowly. Miko grabbed the cable and stepped one foot onto the hook before slowly descending into the shaft. The ground rose to meet her, then surrounded her. The top layer was replaced by the shaft which grew darker and darker until the sunlight was but a tepid shimmer on the bottom floor. She felt rather than saw the shaft open up into the mine. Cool, moist air tickled her exposed skin. The grappling hook clanked against the bottom, startling her. She quickly got her feet beneath her and looked up into the light where the cable ascended. It was only a couple dozen feet, and yet the small porthole of light looked like it was stories above her. “Alright! I’m at the bottom.”

Arcee stopped extending the cable but kept it hanging there. “Alright. Don’t get lost down there and make me come dig you out.”

“Yeah, yeah.” The dark seemed to absorb Miko’s voice, capturing it just a few inches in front of her face. She clicked her flashlight back on then held it over her shoulder. A blinding white beam illuminated the cave in front of her. The walls were a smooth, glistening black, hollowed from the Earth by however many eons of water extraction. She scanned with her light, punching through long open tunnels for hundreds of yards without seeing the end of it. She took a deep breath of humid cave air. “Here we go. Please be easy to find.”

Miko meandered through the cave, eyeing every bit of wall for the telltale blue gleam of energon. She remained slightly hunched, having to weave her head around the few stalactites that textured the ceiling. It was only a few inches above her head, requiring her to pay attention to it nearly as much as the wall. On occasion she would kill the flashlight and peer through the black, hoping to catch something. Hues of blue, purple, and orange swam in her vision as if her eyes were closed, making her question whether anything she might have seen was real or not. “I could be doing something way better than this right now,” she hissed to herself. “Literally anything besides this bullshit.”

She had some luck. Trudging through the tunnels she managed to spot some sparkles of energon encrusted in the walls. “Here we go.” Drawing her bag around in front of her and the chisel that was inside it, she began carving away at the wall. She freed the valuable resource pebble by pebble, catching them when they popped out and putting them in her bag. It never grew old just looking at it sit in her hand, glowing brightly enough with its shimmering blue to cast the shadows of her fingers on the wall.

Her trek through the cave carried on. The few bits she found in the wall were nice, but they weren’t the mother lode. Mere rocks and pebbles weren’t going to feed a base full of hungry Autoboots. If the energon detector was worth its salt, then it had to be close. I’m not going to walk around this cave all day looking for it though, Miko thought.

Then something fantastic showed itself. Coming into another tunnel, Miko spotted a terrific glow in the distance. She shut her flashlight off to confirm that it was real. It had a sort of jade green glow, much unlike the usual cyan energon boasted. Whatever it was, she hustled towards it, praying that it was the mother lode so that she could get out of there. It revealed itself around a corner, almost blinding Miko as she happened to look right into it. She shielded her eyes with her forearm. Once her eyes had adjusted with a few blinks, she lowered her arm to find a fantastic assortment of enormous energon shards jutting from the cave wall, illuminating the space around it with that alien green glow.

“Holy shit,” said an astounded Miko. In the many years since she had begun mining for energon, she’d never seen it glow this color. Looking into its crystalline structure she saw the ebb and flow of not only green, but a foggy white and a haunting purple. The light seemed to throb like a heartbeat, pushing on Miko a crackling energy. It dotted her pupils with a bright glimmer. Far from being blinded, it demanded every bit of her attention and wonder. Is it even energon? Miko came closer. She reached out for it. Maybe it’s a different strain or something. If I show it to Arcee, would she-?

Brrr-ZAP!

The very moment she touched the crystal there was a bright and violent crack of energy which struck her finger. It ripped through her body, illuminating her bones, musculature, and nerve endings from head to foot. Miko shrieked and snapped her arm back, shaking it. Her eyes bugged and her heart pounded. She grabbed the wrist of the afflicted hand to inspect the damage, but she couldn’t see any. “What the fuck?” A quick pat down around her body revealed nothing. There wasn’t any pain, though the surprise still echoed through her body like an explosion, keeping her terrified. What was that? What is this stuff? Energon doesn’t do that.

The crystals started to glow brighter. Their steady pulse grew heavier, garnering a low humming sound like a generator. Wrrrrrr-Rrrrrrr-Rrrrrr-Rrrrrrr. Miko stood in shock, unsure whether to run away or watch and see what would happen. The jade glow reached an apex bright enough to squint Miko’s eyes before it seemed to warp itself in the air, retracting from the walls and funneling into a cone shape that pointed directly at Miko. A sharp inhale sucked into her mouth, totally involuntarily. Across her body there was a thrumming of some kind of energy. It resonated through her flesh and bones, pulsing along with the crystals’ glow.

Miko peered down at herself, mouth agape, body trembling. “What… What is this?” The body-wide energy started to retract from her head and toes. She felt it creeping up her legs and down her neck. It made her skin erupt in gooseprickles and perked her nipples. It passed her navel, then her mid-thigh before finally collapsing into a nucleus around her loins where the funnel of green light was spotlighting. “Hah! Hah! Hah!”

The buzzing sensation intensified. It was no longer as deep as her bones, but it highlighted the flesh of her womanhood, igniting an arousal hotter than anything she’d experienced. It quivered her inner thighs and made her face go red. She started panting, “Huhhh! What? Huhhh! What’s going on?” The crystal’s humming grew louder; the pressure on her nethers grew stronger. It felt like her sex was being molded into something else from the inside out. “Oh God… I gotta… Huhhh… I gotta…” Miko grabbed the waistband of her pants and jimmied them down her hips alongside her underwear, leaving her ass bare. One hand went to her nethers and dug a single finger into her quim, feeling the hot moisture of her growing arousal.

There was something else too. It came from the root of her vaginal canal, quickly making its way to the surface. She looked down at herself, terror growing. “Wh-what?” Whatever was growing took hold of her clit and made it grow. It reached out between her two fingers, fattening along the way into a small yet significant cone of dense, sensitive sex flesh. Miko saw it peak out from underneath her, its bitty pink tip shaped like the head of a penis. “No! What’s going on! STOP!”

The crystal wouldn’t listen. The job was only just starting. Wrrr-Rrrrrrr-RRRRRRRRR- The green glow found the few rocks of energon Miko kept in her bag. They began to rattle and change form, their bright blue aura quickly turning into the same green as the large crystal. Their light was siphoned through the bag and into the mother. Soon the entire cave’s energon was being tapped into, their blue glow turning green and joining the funnel of light. All that energy was poured into Miko’s crotch, accelerating and intensifying her cock growth.

Arcee heard Miko’s scream. It blurted from the crater as she knelt with the cable still hanging down inside it. “Miko?” Arcee bowed over the hole and yelled into it. “Miko! What’s wrong?”

Miko heard Arcee’s voice only dimly. It was but a whisper compared to the roaring crystals now turning her womanhood inside out. What had been a beady little clitoris was now a genuine shaft of dense cock flesh replete with glans and a cock slit. Veins wormed up its length from the root, accompanied by the appropriate filaments and textures. The skin of her cunt lips closed around it and swept towards the head which had swelled into a fat, healthy flare. Below the base of her growing shaft dropped two round orbs. They swelled the skin around it, turning it into a heavy, distended purse. Every organ that functioned as female parts were now stretched and woven outside of her, 100% male.

“Oh my God. Oh my God. Oh my God,” panted Miko. Her hands were ready to grab and tug at it to see if it was real, but the thought of just touching it terrified her. She didn’t have to, not when she felt the chill of an errant breeze wafting across her new organ and making her buttocks shiver. A timid hand reached down for it and held underneath it. Hot, heavy, turgid, it was very real. She felt a pulse at its core. Running her hand up to the foreskin and tugging on it brought the faintest feeling of pleasure. Flexing her floor muscle made it bounce. “Oh God. Oh fuck!”

“Miko!”

The voice came from behind her in the distance, startling her. “Arcee?”

“Miko! Is everything OK? Do you need me to get you out of there?”

That’s a good question. Miko wasn’t in any real danger, but the longer she stayed there the more she risked letting her body change. Her penis and testes were both still growing, albeit slowly. How the hell was she supposed to tell Arcee about it? How was she supposed to tell anyone about it? Was it reversible? Could she hide it forever? What was she supposed to do? “N-no!” she called out. “I’m fine! I… I just tripped! I’m not stuck!”

Arcee, still staring down into the shaft, frowned. That didn’t sound like the scream of someone who tripped. “Are you sure?”

“Yes!” Miko shouted back. “Don’t come down here!”

That just confused Arcee further. What the hell is going on down there?

Whatever Miko’s decision, she had to make it fast. The crystals weren’t done with her. When the energon in her bag was depleted, the crystals reached deeper into the cave for other sources. There were plenty of boulder-sized rocks and thousands of pebbles Miko hadn’t found yet. The crystals drew their energy through the Earth, accelerating the transfer of power into Miko’s crotch. She felt it like a freight train in her loins, physically making her hips jolt backwards and drawing a moan out of her. “Hyuhhh~!”

Her cock growth accelerated. She was forced to watch while doubled over, her knees knocked together by the humbling arousal that glowed so brightly in her package. “Hah! Hah! What is this?” The crystal light grew brighter, the humming grew louder. The slow outwards reach of her penis turned into a race to grow bigger and bigger. The veins webbing the shaft pulsed visibly and continued their wormy march up her shaft as it grew. More than just growing longer, she achieved an impressive girth like she’d never imagined on a man. She didn’t just have a penis, she had a monster worthy of the envy of every man in the world, and it was still growing.

Her whole body vibrated under the intense pressure. Her cock was hard like stone. Every throb of her floor muscle sent a fat, glassy tear of precum globbing out the tip and splatting the cave floor. The orbs hanging in her purse were the size of tennis balls, but the weight of arousal made them feel like bowling balls. In a desperate attempt to make herself stop growing, she grabbed her shaft with both hands. That did nothing besides peel the foreskin back a little. With more and more girth the tips of her thumbs and middle fingers were pulled apart, that devastating pole now more something like a a tree branch than a penis.

Miko’s jaw was clenched. Her face was ablaze and her toes were curled inside their boots. “Please… Make it stop. That’s enough…” She went unheeded. Her newly acquired pecker grew and grew, outreaching the length of her arms, then her legs, then the whole of her body. Between her thighs were a pair of nuts like basketballs fit to break cinderblocks. Jousted in front of her was a column of raw masculinity so immense and powerful that she felt ready to topple over.

Then, as quickly as it had started, it came to an end. The cave had run out of energon, and the green crystals ceased pulsing and glowing. Miko, with her titanic cock and balls, was left in the absolute blackness of the cave. She plummeted to her knees, hands on that reproductive howitzer, balls on the ground, trembling and gasping. “Fuck. Fuck. Oh God… Hahhhh… The flashlight…” She’d dropped it during the commotion of having her finger zapped. She groped around the cave floor blindly before knocking her finger into it and sending it rolling away. “Shit!” She meant to get on her fours, but doing so tapped the head of her erect cock on the cold floor and made her jolt. One hand had to hold it up against her belly while the other rapidly patted around the cave floor in a desperate search for the flashlight. She noticed how the cock head reached more than a foot over her head. With the shaft between her breasts it felt like she was hugging a tree trunk.

She found it at last, the cold metal cylinder landing underneath her hand. It hadn’t worried her whether she was going to find it and get out of there; if things got desperate, she could’ve called upon Arcee to come dig her out. But that wasn’t her main concern. What fretted her the most was showing Arcee what had become of her sex, now a thunderous spear of hot, throbbing man flesh. Miko stood up and clicked the flashlight on. Aiming the beam down at her pecker struck her with how surreal it was. That’s mine. That’s my penis. The part of her that was disgusted sat with the part of her that was amazed. Either way, she had no idea what to do with it. How’s Arcee going to react? How will the others react?

Only one way to find out. “This is going to suck,” she said with a groan as she turned to head back. Walking proved difficult, each pump of her legs knocking into a testicle and making her penis sway. She found the entrance shaft and Arcee’s cable still hanging down from it in a column of sunlight. “Arcee,” she called out. “I’m coming back up.”

Arcee was sitting crosslegged next to the hole, fidgeting with concern over how Miko was. “Oh yeah? Is everything alright down there? Was there any energon?”

“Uh, yeah, there was, but it’s all gone now.”

“Gone? What happened to it?”

“It, uhh… It changed me.”

That just confused Arcee even further. “Miko, what happened? Did the energon disappear? Is that why you screamed earlier?”

Miko couldn’t muster the strength to say it out loud. “I’ll have to show you. Pull me up.”

Arcee’s concern only deepened. “Alright.” She waited for the tug on the cable and Miko’s go-ahead to start reeling in the cable. Once that had happened, Arcee retracted the grappling hook and Miko back towards the surface. Miko ascended the shaft with one hand on the cable, the other holding her penis up against her torso so that it wouldn’t scrape the shaft wall. She watched with some trepidation as the bright portal of sunlight grew closer, then shrouded her head as she breached the surface. Imagine Arcee’s absolute shock when instead of Miko’s head there came the fat, foreskin-swaddled tip of a giant human cock. “Miko! What the hell is that!? What happened to you?”

Miko stepped onto the ground and let her penis flop forward. It nearly dragged her down with it. “Shit! I’m going to have to get used to that. I can’t even pull my pants over it.”

Arcee couldn’t stop staring. She was several meters taller than Miko and yet such a massive cock made her feel small. It made her feel other things too, that which originated deep inside her and made her components stir. “Miko… What happened? How did you get that?”

Miko sneered at her huge cock and rubbed it despondently. “That’s what I’m wondering. It’s not fake. I found green energon or something. It was a big crystal that I thought was the mother lode, but I’ve never seen any energon that looked like that. I touched it and it zapped me. I think it used the power of the cave’s energon to build this for me. All of it’s gone down there, and now I have this.” She looked up and saw Arcee still staring. The Autobot didn’t say anything, utterly stuck in place by the phallus pointing at her. “Geez, don’t stare at it like that.” Miko twisted aside to hide it, making it sway this way and that. Of course there was absolutely no hope of hiding something that big.

Arcee blinked and snapped her gaze away. Her face plate was growing warm, so were the parts between her thighs. Calm down. Miko is your friend. “I see. I… I’ve never heard anything like that ever happening. It must have been tainted energon.”

“Do you think there’s anyway to reverse it?” Miko asked. She gave her cock a squeeze. “God, it’s so hard and heavy. Fuck. My balls too. I can feel the stuff inside it. Is this what guys feel when they’re horny? How do I make it go away?”

Arcee’s spark crackled in her core. “I think I know a way to make it go away,” she said before realizing what she was saying. Stop it! urged her conscience. “The erection, that is. I don’t know what to do to get rid of that cock, but I do know what you can do with it.” What am I saying? Why am I saying it? But she knew exactly why. Jutting from Miko’s loins was what she’d been dreaming of in a man for a long time. It was finally here in front of her, but it just had to be attached to her friend Miko, a woman. For whatever reason, Arcee didn’t mind. Indeed, she seemed to prefer it that way.

Miko looked up at her. “What… What do you mean?”

Arcee’s faceplate grew even hotter. “I mean what else is there to do with a cock like that?”

Miko had caught on, but she didn’t want to believe it. “Arcee… What are you saying? You’re not making any sense.”

“Miko, do you know how Cybertronians reproduce?”

That caught Miko off guard. “Excuse me? No, I don’t. Why-?” She paused when she saw Arcee reaching for her groin plate. It came off with a loud click, something Miko didn’t even know it could do. Arcee let it fall to the Earth where it clattered between her feet. In its wake was Arcee’s loins and the soft cunt that bisected it like any human female’s. Black like the artificial flesh that covered Arcee’s pelvis, the inside was a bright blue color like her eyes. Arcee parted the lips with two fingers, flashing Miko with that sky blue and the beady clit hidden within. Miko’s eyes went wide. She gasped at the same time a throb made her cock bounce. “Arcee… You had that the entire time?”

“Surprised?” Arcee ran her two fingers back and forth across her womanly slit, sloshing the vulva around with them. “We Cybertronians don’t just reproduce magically, nor are we manufactured like the machines you see here on Earth. We breed the same way animals do, and we’re quite good at it.” She gave Miko a shy smirk.

Miko was barely listening. She gawked at Arcee’s flesh portal. Beyond surprising her with the fact that it existed in the first place, it elicited a physical reaction in her that it wouldn’t have before she gained a phallus. That intense pressure on her balls tightened once the juices started flowing. Another automatic throb of her cock muscle sent a droplet of precum drooling from her cock tip. Her cheeks blushed when she realized she was staring. Her gaze snapped away. “That’s cool, I guess. I mean, I guess I never thought about it.”

“Are you thinking about it now?” Arcee asked. Her hand continued to make merry with her feminism.

Miko peered up at her. “What?”

“I said, ‘are you thinking about it now’.”

Miko hadn’t been, actually, but now she was. Between Arcee’s legs. Arcee on top of me. From behind. Hard as I can. Deep as I can. Cumming deep in her- Miko shook those thoughts away. Her entire face was beet red. “No, not really,” she insisted, though not very convincingly.

“Well, I am.” Arcee fell into a squat and sat back on the ground. She leaned back on one arm and opened her legs, showing off the way she gently fingered herself. “Seeing that cock of yours has got me fired up. It looks like you’re raring to go just as badly as I am.”

That much Miko couldn’t deny. The line of cock drool connected the tip to the ground in one long, continuous thread. Every other moment she would clench her floor muscle and perform yet another bounce with her cock. Such arousal burned through the rest of her, making her cheeks red and having her pant softly. The slightest glance at Arcee’s cunny added fuel to the flame. The way she played with it so delicately wasn’t helping, nor that sultry look on her face. For the first time since Miko had known her she was really noticing how she was built. Arcee was not just a towering robot who thought and felt, but a lithe, feminine woman complete with athletic curves and a heavy set of breasts. “Y-yeah,” Miko admitted finally. “I am.”

“You want to put that cock in action, don’t you?”

Miko kneaded her fists. “Fuck yeah, I do.”

“Come here then,” whispered Arcee. She pried her flower open into a diamond shape, showing off the cavity’s inner azul. “Show me what it can do.”

Miko hardly knew what she was doing before she was peeling out of her shoes and shoving her pants and underwear down her legs. This is crazy. Arcee is my friend. And yet she approached her friend at a speedy pace, that giant dick of hers bouncing and wagging like crazy along the way. Once she got close, she was better reminded of their size difference. Arcee was taller than her by a couple magnitudes. Just the top of her bent knees went over Miko’s head. Even so, the fire in her loins drove her to come closer so that she fell into the fog of Arcee’s cunt heat. There Miko could see the finer details of Arcee’s quim. It looked perfectly human except for the colors. The surrounding black of her groin was like skin. The inner blue held a sheen of bodily moisture. At the upper corner Miko could see Arcee’s cunt pearl and the thin layer of labia that shrouded it in a hood. Staring at it so intensely, Miko saw not a robot, but a woman in the dearest of heat demanding her seed.

“Well? Are you just going to stare at it, or are you going to fuck it?” Arcee asked. She sounded playful, but just the proximity of Miko’s giant dick had her ablaze. It was her everything not to reach out and pull Miko into her.

“Y-yeah, it’s just…” Miko rubbed her hand down her cock. “Sorry, but I’m a little inexperienced when it comes to fucking girls. First time havin’ a dick and all.”

Arcee chuckled softly. “Here. Let me help you.” She reached for Miko with a giant, mechanical arm. Miko tensed seeing it come for her, then relaxed when she felt Arcee’s gentle grip around her member. A buzz of electricity rippled through them both. A tremble beset Arcee’s loins. “So big,” she purred. “Bigger than many of the Cybertronian men I’ve been with.”

Miko’s teeth were sunken into her lip. Just the soft brush of Arcee’s fingers sent pleasure radiating throughout her manhood, adding weight to her arousal and juicing more precum. “Mmf. You’re kidding.”

Arcee shook her head. “Not at all. You’d think it’s hilarious how small their cocks are compared to their bodies. You humans are much better equipped for that sort of thing, at least compared to your body size.”

“Yeah, well, this ain’t exactly average. Calling this a third leg would be an understatement.”

“Mmhmm, and I think it’s perfect. Come closer for me.” Miko obeyed with a short shuffle. The cock head loomed in the space just above Arcee’s pussy where Miko could feel a singeing heat. Arcee laid it on her girl lips. A gasp swept through her mouth which wore a gleeful smile. “Oh yes~ This is perfect.”

Miko was holding onto Arcee’s legs for dear life. It was a struggle not to just slam her cock forward, breaking Arcee’s cavity and plunging to the absolute depths. Holding her back was the fear of hurting her friend and/or herself. She’s made of metal. Smashing my dick on that can’t feel good. The glans flared out well beyond the swell of Arcee’s cunt lips. “Are you sure it’ll work? I know you’re way bigger than me, but I might be too big. I sure look too big.”

“Oh, I’ve taken bigger,” Arcee said. “With toys, at least. Now that it’s the real thing I’ll enjoy things much, much more. Especially since it’s you.”

Miko looked away bashfully. “Stop it. You’ll make me blush.”

“You already are. You look cute. Cuter than usual, I mean.”

“Sh-shut up.”

“I will once you’ve start fucking me.”

“I’m getting there. So do I just… push?” Miko wasn’t ignorant or even innocent to the process. She’d laid with men before, but being on the other end proved a totally different monster.

“That’s right,” said Arcee. “Don’t worry. I’ve got you where you need to be. Just put it in. Don’t worry about being gentle. Like I said, I’ve taken bigger.”

Miko couldn’t wait much longer. Raw desire had turned her legs and buttocks shaky. She needed to fuck, and here was a beautiful robot offering the best kind of help. “Alright. Here I go.” Miko pressed her hips forward, compacting the head of her cock on Arcee’s flower. A shudder was shared between them as their sexes collided, the growing pressure felt by them both most sincerely.

“Ohhh…” sighed Arcee, her jaw hung in an erotic O-shape. She craned her head forward to watch that majestic fuck stick make an entrance on her, those sensitive woman lips distending slowly. She saw Miko’s face wince and contort. Arcee kept her going with a few words of encouragement. “Come on. Just a little harder. Huhhh… Keep going.”

A hiss sucked through Miko’s teeth. “I’m going,” she wheezed. Her hips kept pressing forward until she couldn’t reach any further and she had to take one small step forward. That was the threshold of Arcee’s cunt which fell open around Miko’s cock helmet with a sudden, wet jerk. Both women gasped sharply. Miko jerked forward a step by the sudden intrusion. She watched as the flesh of Arcee’s loins gaped and bulged around the shape of her glans. It was so incredibly tight, so warm, and so wet. Arcee milked her for a kind of pleasure she didn’t expect, similar to being penetrated, but reverberating with the existential need to fuck even deeper.

Arcee’s head was thrown backwards. Mouth open, eyes closed, she threw her moans to the sky. “Ohhhh… Yes. Oh that’s amazing. Fuck.” The tip of her middle finger hooked and orbited at her clit even as it bore the brunt of Miko’s heinous cock girth. “Deeper,” she begged. “Go deeper. I want to feel all of it inside me.”

Miko would’ve loved to deliver, but Arcee was just so tight that she was paralyzed. Her whole body vibrated, barely able to withstand such a womanly choke on her cock. Every pulse of her heart had the cock muscle throbbing and bleeding more of that thickish precum. “Ffffffffffuck. I’m trying, but hoooooly shit that’s tight. Hahhhh…”

“Mmmm, you can do it. Just take your time.” Arcee tried to sound patient, but the swooning emotion in her tone all but demanded further penetration.

The thrumming urge in Miko’s balls delivered the same tone. “Mmf. Yeah. Here I come.” Miko took another step forward. More of her cock dipped inside of Arcee with an audible skwish. Pleasure bit at them both, making Arcee’s metallic legs quiver and rattle. Miko paused to take a breath, then forced another step, then another. Watching more of that flesh column vanish into Arcee’s flesh portal was almost as rewarding as her Draconian grip. “Fffffuck. So tight. Hahhh…” She trucked her way forward step by arduous step, watching that cock bulge in Arcee’s pelvis creep its way into her abdomen.

The mighty transformer shook like mad. She had to balance herself with both hands behind her just to prevent toppling over backwards. “Ohhhhhh! Yes! Deeper. Come on. Deeper. Yes. Ohhhh, it’s so good. So big. Huhhhh… Fuck me. Please.” At last, Miko was down to the root, those cantankerous cum tanks squashed against the underside of Arcee’s buttocks. Arcee felt that blissful fuck stick all the way to the core, its blinding delight humming through her circuits. “Huhhhhhh! Yes… Yes~”

Miko stood there trembling just as hard. Every inch of her cock felt ready to collapse within Arcee’s cunt grip. For that mild discomfort was a flood of white-hot joy already putting her on the brink of cumming. She held onto Arcee’s hips for dear life, not wanting to back out a single inch lest she lose out on such a bodily euphoria. Her eyes crossed in their sockets. Haughty huffs beat out of her mouth. “Hahhh… Hahhh… Fuck, Arcee… Holy shit. Huhhh…”

“Mmmm, start fucking me,” Arcee commanded. “Yes. Huhhh… Fuck me. Cum inside me. Please. Please. Huhhhhh…”

Again, Miko was inexperienced in such an art. This time, however, she had instinct to rely on. With her crystal-endowed pecker was the inherit need to breed and genetically engraved instructions on how to fuck. Miko’s hips arced backwards as far as they could go, drawing just a foot of her column from Arcee’s sorely stretched cunt. They returned with a mighty thrust powered by the clench of her glutes. Their bodies collided. Those two giant balls crashed like wrecking balls.

Arcee’s head was thrown backwards. Her bosom jutted into the air along with it. “Hyuhhhhh~!” More feminine wails belted out of her as Miko repeated, withdrawing and fucking at what started off as a steady rhythm then escalated into a series of pelvic slams. In someone so much smaller than her Arcee could feel the power in those heaves. There was the clench of her glutes and the crunch of her abs. Looking down at her through the gap in her breasts and thighs she saw Miko clinging to her, that pretty face scrunched with effort, streaked with beads of sweat. It was too much for Arcee. Her arms collapsed from behind her, sending her back slamming into the Earth with a great whoooooom! Her moaning did not pause. The pleasure aching through her body had her writhing and clawing at the dirt. “Huhhhh! Ohhh! Yes! Miko! Huhhhhhh!”

The sudden collapse and crash hardly fazed Miko. She took it as a sign of her success, encouragement to fuck harder and faster. That she did, ringing the sounds of her flesh striking Arcee through the forest. PLAP! PLAP! PLAP! PLAP! PLAP! PLAP! Her own moans joined the cacophony. It was an effort and a half maneuvering that giant breeding tool as hard and fast as she did. Whatever fatigue there was could be ignored for the swelling delight and inevitable orgasm. “Hah! Ffffuck! Huh! Hngh! Shit! Arcee! Huhhh!”

“Huhhhhhhhhhhhhh~!” Arcee’s hand went back to her pussy to lay siege to her clit. The tip of her middle finger swirled and hooked at it even as Miko’s cock was pounding it so mercilessly. It was the final addition to her ecstasy that had her barreling towards the edge. Her moans hit an added octave. “Mmmmm, Miko! I’m cumming. Yes! Oh fuck… About to cum! Yes, yes, YES! HUHHHHHH~!”

Miko meant to tell her the same. An explosion was ready to rip out, christening her knew fuckstick and Arcee’s womb. The words needed to articulate as much escaped her thanks to the building pressure about to pop, thus she was reserved to heavy grunts and Arcee’s name. “Hrrnnggh! Arcee! Fuck! Hahhh! HUHHH~!”

Arcee’s pitch was on the rise, hitting an apex before suddenly crashing into a throaty caterwaul once her orgasm had finally arrived. Her fuselage swung into a steep arch, that lithe tummy at the vertex while the top of her head laid flat on the ground. “_HYEEEEEUUUUUUGGH-

HHHHHHHUUUUUuuuuuuhhhh~~~!!!_” Mighty spasms beset her womanhood. Every modem and circuit running through her was run through by the brightest energy, crackling, fizzling, burning, sparkling energy of the most delightful order. The cavity woven around Miko’s cock collapsed into a fit of contractions.

That was it for Miko too. She, too, experienced a violent backwards heave of her back. The cords in her neck stood taut as the hard clench of her jaw strained a loud, guttural growl. “Hrrrnnngghhhhhhhhhh~~~!!!” Squirshhhh. Squirshhhh. Squirshhhh. The cock muscle collapsed and throbbed at a steady pace, jettisoning everything she had in her cumtanks with enough force to fill Arcee’s womb in just a couple pumps. The balls lifted in their purse, leaving no drop unspent. Miko’s grip on Arcee’s thighs was like iron. Her shaky legs made the fat of her glute-dimpled haunches jiggle. Midway through her eruption the ferocious expression on her face broke into an emotional look of ecstasy. “Nyaahhhhhh~!”

The two lovers shared their climaxes for several moments before gradually the excitement died down. Arcee’s back lowered to the Earth. Her eyes were closed. Blue and black stars darted behind her eyes and throughout her muscles. The joy receptors throughout her circuits had been fried. It would take a lot to match what they’d just been through, a high Arcee would chase for the rest of her life. “Huhhh… Huhhh… Miko… Wow… That was… incredible. Mmmmmm~” She rubbed the space above her cunt where she could feel the density of Miko’s cock buried inside her. Frothing in front of it was a molten load of cum more voluminous than she’d ever received. “You’re pretty good with that thing. I’m glad you got it.”

Miko was still catching her breath. Her legs felt ready to give out beneath her, they were so numb. Gradually she was able to lift her blushing face and look at Arcee. “Yeah. Whooo… I think… I think I am too. God…” She let go of Arcee’s hips and slowly backpedaled away, withdrawing her softening pecker. Schllllllllllllllp! The glans popped free like loose rubber and flopped downwards. It was lathered in cum, both Miko’s and Arcee’s. A tidal wave of it came glorping out of that battered pussy in a thickish ooze. Arcee gave her floor muscle a heave, releasing a fat slug of cum with a gurgling belch. “Fuck. That’s a lot.”

“Mmmm, it is~” Arcee purred. She sat back up and leaned on her arms. She saw Miko standing between her legs holding her limpened breeding tool. “What’s wrong?”

“Nothing. It’s just… How the hell am I supposed to hide this? I mean, it’s pretty fucking awesome. I love what it’s capable of, but I can’t go around wagging it like a flag in front of everyone’s faces. Is there anything I can wear over it? Is there any way to make it smaller?”

I sure hope not. “Look. Why don’t we head back to base and see if anyone can find out what that crystal was. I’ll get you there on the offroad where fewer people will see it. I bet one of the scientists can help.” In the meantime, I think you and I will get more acquainted with it.

Miko wondered if she wanted to get rid of it at all, if maybe she could just cover it up somehow. Because this thing is too fucking awesome to get rid of. “Yeah, let’s do that.”

“Alright,” Arcee said. “Hop on.” Arcee folded into her motorcycle form. Miko dragged herself and her cock towards her. She climbed on half naked with her shriveling penis and obese scrotum laid flat on the seat cushion. The motorcycle drove off, prepared to take the long route home and dripping cum from its exhaust pipe.

THE END
