Grease Pan looked over at it, half eaten frozen pizza in front of her forgotten as she waited for her flatmate to step inside the flat. A moment later the door swung open and a small earth pony mare stepped inside. She had a caramel coat and a chestnut mane. Those weren’t the most distinctive features of her though, the black composite legs she stood on really drew your eyes. That was kind of her job, stripper at a club in the city. “Do you want some pizza?” I asked her as she put her coat on the rack. “Sure,” she replied as she turned around and walked towards the little island in our flat. She had to jump to reach the top of the barstool. I just sat down on them. We were kind of opposites, and not that different at the same time. I was a unicorn mare with that was a lot bigger than average. She was a lot smaller than average. She sold her body to horny stallions and mares, with only a thin pretense of legality. I used my body too, as a testing platform for damage that would maim or kill a regular pony. Well, a regular pony without as many augments as me. “You want a beer too?” Pan asked her as she pushed the pizza towards her. Fuzz grasped it with a foreleg, small finger analogues shooting out of the end of her legs. Pan was power, Fuzz was deftness. “Fuck yeah, I don’t work till next thursday,” Fuzz punctuated her words by pumping a hoof into the air. I wasn’t sure if the pizza grease on the fingers undercut the words, or not. It really didn’t matter. Grease Pan grabbed two beers from inside the fridge, before dragging them over to herself. There was a piece of metal where her barrel met her steel coloured legs, and it worked perfectly as a bottle opener. And so, she did just that. There was only a small chance that the beers would erupt and spray foam into the gaps between the moving parts of her legs. But, even if that happened, they were properly weatherized to survive hurricane winds and wash. Beer wasn’t a threat to her. Especially considering she routinely got hit by carriages. “Thanks,” Fuzz said as she took a large pull off of the bottle. Pan went back to the island, sitting her still mostly organic ass on the stool. “So, how was work?” Grease Pan asked as she stared down at the much smaller mare. “Well, I had a stallion who blew his load the moment I sat in his lap,” Fuzz replied before taking another bite of the subpar pizza. “I mean, he only paid for a lapdance, so I guess he got his money's worth.” “I got had a stallion shoot a tear gas canister at me,” Grease Pan said while nervously stroking the back of her neck with a foreleg. “If I could trade jobs with you, and like, survive it, I would probably try it,” Fuzz said before letting out a laugh. “If you had sat in his lap, he still would have cum, but you might have also broken his pelvis.” “If he was smart, he’d get a reinforce pelvis, it’s not my fault that most ponies can’t handle me,” Grease Pan remarked before standing up and stretching. “Honestly though, I’m more surprised that neither of us have gone into heat. It is March.” “You just had to fucking say it Pan!” Fuzz stomped a metallic hoof on the counter. “Oh come on, we’re both rational cyber mares,” Grease Pan said with a childlike lilt in her voice. “Don’t tell you actually believe that garbage.” “Equestria used to have real magic, Chaos gods, Sun goddesses, even a princess of friendship, whatever the fuck that meant,” Fuzz shot back in a voice that spoke of vexation instead of anger. “So that ancient magic somehow proves that making a fate tempting remark is a bad thing to do?” Grease Pan said with a laugh. “You just don’t do it! There’s no benefit to tempting fate, and everything to lose!” Fuzz said before jumping off of the stool and shotgunning the beer. “I’m going to take a shower, get the residual traces of sad stallion seed out of my fur.” “The good old triple S,” Pan said with a laugh, before knocking back her own beer. The bubbles felt good in her throat, and the hoppy nature of the beer made her realize she was drinking beer instead of water or piss. There was a note of resignation as she got off of the stool and strode to the bathroom door. “Hey can I come in and brush my teeth and pop some Melatonin.” “Greasy, I’m a stripper who turns tricks on the side, I don’t give the slightest shit,” Fuzz said. As Pan opened the door she could hear her flatmate laugh, her eyes did drift to the wet coat and mane of the other mare. It was only a slight glance. Pan had never asked if the other mare was pansexual, like she was. Or even if she liked sex at all. Then again, an Asexual stripper seemed like a bad fit for a number of reasons… “Are you just gonna stand there? I mean, I normally like the attention, but you have to work in the morning,” Wireless said through the frosted glass of the shower door. “Y-yeah, right,” Grease said before turning towards the sink and the medicine cabinet above it. For just a moment she looked at her reflection in the mirror. Her green adjacent mane cut short, and a face that looked entirely equine. If she kept her line of work, that would change. She had already had a couple close calls, nearly having her visage destroyed in a way that couldn’t be put back together without composite and wires. That thought gave her pause. There was no way to live forever naturally. But ponies who had forgone their original flesh and bone, they were living for hundreds of years… Grease Pan shook her head and glanced at her flatmate, she was massaging shampoo into her mane, and humming a little tune, barely audible over the roar of the shower. What would she choose? She had lost her limbs in an accident, and that was all the machine in her. Grease Pan had chosen to be augmented, to be better than the body nature had given her. She could crush I-Beams and survive impacts that would liquify other ponies. Natural ponies. “Do you want to live forever?” I asked her as I pulled the medicine cabinet open. The bottle of gummy melatonin sat there glistening in the harsh yellow of the fluorescents. Everything was artifice. Maybe it always had been. “Fuck no, if I can’t fuck things, or enjoy harming myself, then what’s the fucking point?” Wireless Fuzz said with a glance at me. She had to stand on her hinds to reach the cabinet. I could’ve manipulated the highest shelves just by craning my neck. “That’s a better argument than most,” Grease Pan replied before shutting the cabinet and picking up her toothbrush in her magic. After she finished brushing her maw, she sprayed off the bristles under the sink and threw it back in it’s holder. “Goodnight.” “Night Grease,” Fuzz said as the larger mare made her way out of the room. Down the hall, her bed beckoned. With a yawn she closed the distance. The sheets felt nice underneath her, and the stack of pillows under her head were the perfect compromise between cushion and stiffness. For some reason, that word in her mind echoed. Stiffness- “Probably just the beer,” Grease Pan said to herself before closing her eyes and waiting for sleep to take her. It didn’t take long. ---===*===--- Light began to slip through the curtains, it fell upon her body, and it kickstarted a process millions of years old, slowly waking her out of the deep rest cycle that all creatures shared. The moment that the magic of consciousness flipped on, Grease Pan realized that her odd thoughts last night weren’t an aberration, they were foreshadowing. She looked down at her body, and if you drew a straight line from her head downward, you’d arrive at the source of the problem. “Oh fuck me,” Grease Pan said with a huff. Her nethers were soaked, and there was already a wet spot on the sheets underneath her. Without thinking about it, she pulled her phone over to her. With a quick look through her contacts, she found her boss. A sturdy earth pony stallion, in his forties, with a scruffy face and a husky, smoky voice… “Damn it all.” She shook her head in an attempt to clear her mind of the fantasies that had filled it. As much as she’d love to go to work and jump her boss, to be filled with a member she had only seen drop out once when he thought he was alone- The dial tone began to ring as she watched the slow rise and fall of her chest. Her pussy was burning, and the urge to at least rub it was strong. Somehow, she resisted long enough for the call to connect. “What’s up Grease?” The stallion on the other end said. “Boss, my season came early,” Grease Pan said with a note of apology in her voice. “Well, that’s fine, just uh, tell me when you’re ready to come back in,” he said in a neutral voice. “Alright, uh, have a nice day?” Grease Pan said before hearing him laugh quietly. “Just try not to jump any poor stallion you run across, heat leave is a lot better than maternity leave,” her boss said before ending the call. She sat the phone down on her night stand and got out of bed, stretching out her legs and arching her back in a habit that had developed back when she had been less hydraulics and more sinew. Her tail stuck to her marehood, and she was sure there would be a trail left behind wherever she went. With a tendril of magic she undid the door and popped into the hallway. Her nose sniffed something verdant, something feminine. It was probably just her own heat finally registering to her own nose… “You’re a bitch, you know that,” She heard Wireless say from the kitchen. She sounded angry. “Huh?” Grease said as she strode into the kitchen to see her flatmate sitting on a stool, a wet towel underneath her rump. “You fucking said it,” Fuzz said before taking another sip of coffee. “Well if it makes you feel any better, I called in,” I said before going to the coffee pot and dumping some of it into a mug. “Why?” Wireless asked with confusion written in her voice. “Oh, yeah, that would do it.” She added after sniffing the air. The next moment she laughed. “I always thought that was a myth.” “What, mares living together having their cycles line up?” Pan asked her as she sat down beside her. “That’s like science.” “There’s a difference between reading something in a book, and actually having it happen to you,” Fuzz said before drinking some of her coffee. “On the bright side, we’re good on supplies.” “You know, you sound like this is a siege,” Grease Pan remarked with a laugh. “There’s an army of stallions out there, and they want nothing more than to use their battering rams on us. To make matters worse, we wouldn’t stop them,” Fuzz said with a laugh that was more bitter than the black coffee Pan was drinking. “So what’s the game plan then?” Grease asked the small mare. “Well, there’s no point in barricading the door, so other than that, try not to go crazy and get rutted and nutted,” Fuzz replied before downing the dregs of her coffee. “I see,” Grease Pan said before rubbing the back of her neck cautiously. “Other than that, it depends on you really,” Fuzz said nonchalantly. “What do you mean?” Grease asked curiously. “You know, you’re a pretty innocent mare,” Fuzz said before jumping onto the floor. The metal tips of her legs striking the ground with a heavy thud. “Uh, okay?” Grease Pan replied as she walked over to the couch before clicking on the screen and starting some drama show. “Mind if I join you?” “There’s room on this couch for two,” Fuzz said absentmindedly. She pulled a blanket off of the top of the couch and draped it over herself. “Which we round up to.” “Yeah, never thought of it like that before,” Grease said before trotting to the couch and sitting her rump down on it. The show was passe, and kinda boring, but it at least kept her from thinking too strongly about the heat. Though with every breath that came through her nose, she seemed to smell the ambient mare scent increase. When she turned her head to look at her flatmate to see if she thought the drama was shitty, she realized something. She had one of her forehooves underneath the blanket. More than that, it was moving in a circle, about where the other mare’s crotch would be. I blushed and looked away, pretending to be a lot more interesting in the screen. But it wasn’t long before I shot a side glance at her. I could see her hips shuddering beneath her, subtly, but definitely. Then I looked back at the screen. “I really wasn’t trying to hide anything,” Fuzz said with a husky laugh. “But do you understand what I meant earlier?” “Uh-” My jaw fell open. I looked at her and felt my own heat flare up between my legs. “I can literally hear then gears turning in your thinking goop,” Wireless said before tossing the blanket off of her in one swift motion. “Do you want us to-” Grease Pan started to say, her eyes drifting down to her Flatmates dripping slit. “I mean, it’s not gay if we’re in heat,” Fuzz said with a broad grin. “Sounds good to me,” Pan replied with a nervous laugh. It picked up an octave when the smaller mare pushed her back against the couch. Pan gasped as the Fuzz nipped her neck, and used one of her hinds to grind against her pussy. The cold metal felt amazing against her heat wracked nethers. “I’ve seen you staring at me,” Fuzz said before biting the larger mare’s neck. “I have,” Grease said before pulling her forelegs around the other mare. The servos and strength of her military grade cybernetics whirred and whined as the neurons they were connected to went off randomly. The next thing she knew, Fuzz had met her muzzle with hers. The kiss was warm, and needy for both ponies. Somehow, the smaller mare won the contest of tongues, pushing into the larger mare’s mouth, and holding her tongue against the bottom of mouth. Grease maneuver her foreleg to rub against the dock of the other mare. Fuzz moaned into her mouth, and pushed her rump up in the air, just high enough for the metal hoof to grind against the dripping snatch. The moan re-doubled as the two of them both ran out of air. Their kiss ended and the two breathless ponies stared into each other’s eyes. “You wanna take this to a bed?” Wireless asked Grease. The larger mare nodded and released her. The smaller mare ground her mound against her hoof one more time, before hopping off of her and starting towards her room. Grease turned her head to watch the slow, sultry steps of the other girl. Fuzz flicked her tail from side to side, teasing her with the pendulous motion, and the frequent flashes of her dripping pussy. “See something tasty?” “I want to bury my muzzle in there,” Grease Pan said with a flush on her muzzle. “Good girl,” Fuzz said before disappearing into the hallway. With a single glance downward at her own nethers, she realized that she was in fact, into girls. “Wait up!” Grease said as she ambled to her hooves, and jogged into the hallway. The smaller mare had dripped a trail of arousal into the carpets on her way through. That realization alone made Grease wink into her tail. When she pushed open the door with her magic, she nearly collapsed from the sight before her. Fuzz was laying on her back, her hind legs spread out, with a vibrating wand pushed into her folds. “I got started without you,” Wireless Fuzz said before her head tilted back and she let out a loud moan. “I could tell,” Grease Pan said as she climbed onto the bed, before lifting the wand up with her magic. She pressed it into the spot where her clit would pop out. And then, she did what she said she would. Grease Pan jammed her thick tongue into Fuzz’s pussy. The smaller mare let out a cry of surprise as the other mare teased her thighs, and stuffed her slit with her tongue. Her clit winked out and rubbed right into the wand. Her metal hooves slipped down towards the larger mare’s head, holding her in place as she felt the electricity begin to build up in her stomach, the tendrils of animal pleasure arcing up her spine. “Come on, I’m almost- there!” Fuzz said after a few minutes of delicious torment. Grease’s tongue was getting tired, and the smaller mare now had quite a few bites on her inner thighs, hickeys that would be rather hard to explain. Well, hard to explain as anything other than what they were- “Aaah,” Fuzz said as her body locked up in pleasure and her nethers squirted out a small pond’s worth of mare juices. Her back arched up, and her hooves pressed the other mare’s tongue and muzzle into her soaked slit. And then, she opened her eyes again. Grease’s muzzle was absolutely covered in her jizz. The Wand was gone though, but she could still hear the humming of it’s little electric motor. “Huh?” “I uh, borrowed it while you were cumming over my face,” Grease said before her tongue lolled out and a deep husky moan escaped from her muzzle. Fuzz finally made the connection, Grease’s horn was glowing, and that humming was coming from her rear. “Makes sense,” she said breathlessly, before grabbing the other mare and pulling her forward. She kissed the bigger girl, while opening her drawer with a hoof. “Now, it’s time for the real fun.” Grease Pan looked over at the drawer and her eyes widened like she was about to be hit by a train. Her magic grasped the object of their mutual desire before pulling it in front of their eyes. A girthy, double ended dildo floated in front of their muzzles. “I thought I tested the dangerous hardware,” Grease Pan said with a nervous laugh as the smaller pushed her onto her back. Her hinds spread apart with a soft hiss of electric motors. Fuzz climbed on top of the larger mare, before lining up their pussies, and sitting down. The tip of the dildo pressed into her tunnel, before spreading it out. The smaller cyborg moaned and grasped at the sheets to each side of Grease Pan. With her magic, Grease Pan took the other end of the dildo and slid it into her. The two of them just took in the sensations of being filled, and panted softly, both from the heat, and their mutual desire for the other being fulfilled. “You know what you could do with that horn right?” Fuzz said as she swung her hips around, changing the sensations flitting up to her brain. “W-what?” Grease asked with a stutter. “The Wand, stupid,” Fuzz said with a growl as she began to push herself up and down the length of silicone. Grease Pan groaned at the pushing and pulling the other mare was doing. It took her pleasure soaked neurons an extra moment to fire, but when they did, it was like a stadium light turning on above her head. Her horn flared to light, before grasping the fallen wand. It only took another second for her to pull it over to the part of the shared dildo not inside either of them. “Oh fuck!” Fuzz said as Grease held the vibrating head to the dildo. The vibrations travelled up and down the dildo, sending all those delicious motions through their bodies, the nerves already set to sensitive were assaulted again. “Ooooh,” Grease let out, as the smaller mare fell down to her chest. She seemed a little more mobile than the other girl, and groped the other mare’s cutiemark with her heavy hooves, pseudo nerves wired into her brain telling her the properties of the other mare’s cute ass with sensitivity designed for scientific ventures. That went on for a while, the two of them bucking and grinding on the dildo, while the vibrations shot up their bodies, their tongues lolling out of their mouths. The moans picked up in a long crescendo, and only a quick application of a sound proofing spell on the part of Grease Pan prevented their neighbors from hearing their pleasure in great detail… “Oh, I’m so close!” Grease Pan said as the smaller mare continued her gyrations. The smaller mare smiled broadly, hungrily at her, before pressing a forehoof into her breasts, squeezing them hard. That was all it took for Grease Pan to cum. Hard. Her cybernetic spine shunted the feelings up to her brain, and her organic lungs and larynx pushed air out her lungs, in a fit of passion and feeling. For a good few seconds the smaller mare just stared at the larger Mare’s face, waiting for the signs of consciousness to return. Eventually, with a sputtering gasp, the unicorn came to. “Okay, now we’re gonna go for a classic.” “Huh?” Grease Pan mumbled. The smaller mare dismounted and pulled the half of the dildo she had been riding out of Pan with her mouth. It was a thought that she couldn’t quite repress, and I mean, they had already gone that far, why not turn the tables. Her muzzle buried into the dripping, sensitive, slit of her friend. Pan moaned deeply, as the smaller mare pushed her tongue into her pussy, tasting her from the source, and enjoying every molecule. “You like that?” Fuzz asked her as she took a moment to catch her breath, her muzzle plastered in juices. All Grease Pan could manage was a slow nod. That was all it took for the stripper to dive back into her honey pot, the smell of the other fertile mare driving her onwards. It was a surprise to her when Grease locked her hydrualic legs, able to withstand impacts from loaded carts and push them back, around her neck. It was hot though, Fuzz was always going to be the one who wore the pants in their relationship, but it was a pleasant surprise to see the larger mare taking a bit of initiative. “D-don’t s-stop!” Grease Pan half-moaned, half-pleaded with her, as she felt the feelings build up in her again. The next crest wasn’t far off, she knew that intimately. Fuzz wanted to say something sarcastic, but she was currently muzzle deep in pussy, so she just focused on getting Pan off. It was a good decision, as a few moments later, the larger mare’s clit winked out, and with a talent cultivated through years of sex, she grasped it with her tongue, and held it in place-\ “Aaaah!” Grease Pan moaned and her hinds locked the other mare in place. She rode out her second orgasm, while feeling the tongue work of the skilled mare through it all. Eventually, though, her body went limp. That was the saving grace for Fuzz. She pushed upwards with all the strength that her civilian cybernetics granted her, and managed to free herself from the heavy steel trap she had been caught in. Her sharp intake of breath was like ambrosia from the gods of mythology. And then, she glared at the blissed out unicorn. “I’m not doing that again, you’re dangerous to eat out,” Fuzz said with a scoff. The larger mare smiled apologetically. “But I can do this,” Fuzz said as she flipped herself around, aligning her pussy with the other mare’s. Pressing them together, and grabbing onto Grease’s heavy metal leg. The leverage was exactly what she needed, as she ground their drenched nethers together. Grease moaned and shuttered as her over sensitive nethers touched the other mare’s. “Don’t stop!” Grease managed to over the flood of feeling. “There aren’t any breaks on this fucking train!” Fuzz replied as she pulled herself against the other mare, and feeling her clit rub against the outer labia of Grease. There was a brief intake of breath on both their parts, as they rode out the feelings of contact, of heat, of mutual desperation. Minutes passed, as the grinding picked up speed, and lost it, as their lungs filled and expelled. All the while the room only became more pungent with the smell of sex. They were both close, breathy, and flushed in all the places that matter. There was a puddle of juices beneath them, and in Grease Pan’s mind she knew that they would be sharing her bed tonight. “I have an idea, grab the wand, put it between us,” Fuzz suggested, in a breathy voice. “A-alright,” Grease Pan mumbled and grasped the wand with her magic and placed the wand in between their mounds. The moment that it made contact they both fell backwards against the bed, their bodies robbed of energy. Grease managed to push herself forward, grinding herself against the bulb of the wand. “G-good idea right?” Fuzz said just before her mouth lolled open at the feeling. “Y-yeah,” Grease Pan said as she felt her next orgasm rush at her, the electricity all flowing from that wonderful wand. They came a moment later, the endorphins shooting into their brains, and their pussies leaking all the more. And so it went for several cycles of brain bending pleasure, their heat, their desperation, their unending desire for more pleasure… Eventually, the batteries in the wand died. It was a good thing ultimately. The two mares were exhausted, sweaty, and absolutely sore. It wasn’t a foregone conclusion that they would both pass out in piles of their own juices. But it happened regardless. ---===*===--- “So, pizza or noodles?” Fuzz asked grease as they sat at the kitchen island, hours later. The two of them were drinking water, sports drinks, anything to replenish their fluids short of an IV. “Pizza,” Grease said instantly. She was starving, they had been out for hours on that soaked bed. The poor wand was sitting on it’s charging station, and their marehoods were both red and sensitive. And, not in a good way. “Alright,” Fuzz said before knocking back another tall glass of water. Her throat was raw, her vocal cords had gotten quite the work out as well. A moment passed where the only sounds were that of the air conditioner and drips from the leaky faucet. “How long do your heats usually last?” Grease Pan asked. “A week, sometimes a little less,” Fuzz replied as she looked over at the large mare. “Yours?” “A week, week and a half sometimes,” Grease said with a shrug. “Wanna do that again sometime?” Fuzz said with a grin. “You know, we don’t have to be in heat to have some girl time.” Grease Pan gulped audibly. “Uh-sure!” Grease Pan said brightly. Her nethers winked again at the thought. Heat was a powerful thing. “Wanna fuck the pizza pony?” Fuzz asked, her look almost philosophical. “That’s a thing you can do?” Grease asked, her visage caught in thought. “Yeah, I’ve done it before,” Fuzz replied before dropping off of the stool and walking around the island. “It’s pretty fun to do.” “What if it’s a stallion?” Grease asked, worry coming into her voice as she thought about a hot throbbing member filling her. “I have the pill,” Fuzz said with a laugh. “It won’t solve our heat problem, but having a cute pizza buck would be worth it anytime.” “Fair enough,” Grease Pan replied. “Wanna take em’ now? Just in case?” Fuzz asked with a smile on her muzzle. One of her forelegs pointed towards the hallway. “Medicine cabinet?” Grease asked as she too dropped to the floor. The scent of horny mare filled the air, and the swinging of the other mare’s tail back and forth certainly wasn’t helping the matter. “The very same,” Wireless Fuzz said as she started down the hall, very much aware of where the other pony had her eyes planted. Her tight little rump swung back and forth, tempting the unicorn mare. The two strode into the small bathroom and pulled the bottle from the top shelf, well, Grease did, with her magic. They popped the pills and drank from the sink to wash them down… ---===*===--- There was a knock at the door, and the two mares got off the couch, the smaller mare having been cradled by the bigger one. They didn’t even realize how much they smelled like sex and heat. Fuzz answered the door, and Grease stood behind her. The moment that the door opened, the nose of the pizza stallion twitched. He looked at them with fear and instinctual arousal. “H-here’s your pizza,” the stallion managed to say. Between his legs, his sheath was already twitching. “Would you like to come inside?” Fuzz said with a predatory gleam in her eyes. He gulped. “S-sure,” he said. Grease closed the door behind him with her magic. And for good measure locked it. The moment that he started towards the island the two mares spun around and let their tails flag…
