Trixie breathed in deeply as her body shuddered. Normally, she would have spent the week somewhere seclusive and quiet, and waited this damned thing out. A performer like her didn’t do well in mating season, as it brought the threat of foals to her career, but also the fact that most ponies didn’t watch night shows when they were busy in beds. This year though, she had extended her time in Ponyville well past when she normally left, and had completely forgotten about mating season. On the plus side, one of the best parts of Ponyville had given her the possibility of a solution, and so she knocked on the door again.
The hard wood creaked on its hinges as the owner of the cottage opened it ever so slightly. Her cerulean eyes peaked out through the crack, before Fluttershy opened it the rest of the way. She smiled at Trixie, a gesture she would have reciprocated if the show mare had not been slightly stunned. The normally reserved mare was currently in only her white bra and panties, which put on full display her soft thighs, and more than full bosom that put almost any mare in Equestria to shame. “F-Fluttershy, w-why are you dressed like that?”
The yellow pegasus blinked for a moment, before a tinge of red came over her cheeks, and her tail slipped over her panties, covering the small butterfly on the front. “Well, I thought my letter was pretty clear, and,” she took in a sharp breath as the the blush on her cheeks grew, “I really need to begin my treatment myself.”
Trixie nodded, not being able to deny the slight dampness between her own legs. While she had considered just staying in her trailer instead of coming over, she was curious as to what sort of remedy for the malady that the shy mare had, and so followed her in. “So, how do you beat this? Some sort of herbal tea, Ice on your crotch, maybe medita-”
“I hope I made them right this time Flutters. I know your pony food can be confusing, but these sandwich things are…” The light green… thing had finally turned around, and now looked at Trixie as they stood on opposite ends of the room. In her hands was a silver tray that sank into her fingers, but also had small, finger sandwiches on it. Hanging just above those were another set of amazing tits, which made Trixie wonder if her double D’s were still special with Fluttershy also beside her. When she looked away from those, she could see the creature’s completely blue eyes, as she had no pupils, and short, darker green hair. The part that made it all the worse for her was that it wasn’t fur or mane color that did all of this. No, you couldn’t see through fur or manes.
The creature shut its eyes and gave Trixie a soft, thin lipped smile. “Oh, you must be Fluttershy’s friend! It’s a pleasure to meet you.”
Trixie slowly turned her head until she was staring at Fluttershy, who was beat red now. “What?”
Fluttershy slowly walked over to the creature in the room, who put the tray down and now wrapped its arms around Flutters and nestled her head into the mare’s shoulder. “This is Sli, the Slime. We met a few years ago, and, well, she is what helps me through my periods of heat.”
Steam began floating off of Trixie’s head as she tilted her head. “And how exactly does she do that?”
“Well, you see-”
“I fuck her.” Sli’s cheeks were a touch red, but she then shrugged, her bare breasts bouncing with the motion. “I mean, I know you ponies don’t like being upfront about it, and I don’t want to offend, but… that’s what you need right now, right? We slimes don’t really have mating periods like this, but it isn’t a hard concept to grasp.”
Trixie shook her head as she tried to stop feeling like she was going insane. Hopefully. she wasn’t just still in her trailer in a lust filled stupor and imagining all of this. “I’m sorry, but even if you try to say that, why would I think it’s… safe to let you…”
The gel that made up Sli’s cheeks brightened further to red as she slipped an arm around Fluttershy. “Well. I could show you by first helping Fluttershy. She was quite excited to have a friend join in our bonding ritual earlier this week, so I see no issue here.”
“Really?”
Fluttershy’s fingers sunk into the slime’s sides as she hid her face with her mane. “Well… yes.” She peaked through the pink strands with a single eye, and stared directly at Trixie. “I wanted to help you, and… and I guess I wanted to share one of my deeper secrets with another pony.”
Trixie took in a sharp breath as she looked between the two, before slumping back into a chair and let her arousal win. “I… I guess I could sit through a demonstration.”
Sli clapped her hands together, while Fluttershy nodded. By the time she rose her head though, Sli showed her eagerness by locking lips with the yellow mare and diving a hand between Flutter’s thighs. Trixie forced herself to not lean forward as she watched the hand slip below the white cloth on those luscious, yellow thighs.
Then came the tendrils.
For now, they stayed calm, only slightly slipping away from the bottom hand and pulling Fluttershy’s panties out of the way. Like this, Trixie could clearly see her host’s sopping wet snatch, and felt her own shiver when she saw the gelatin slowly glide over the folds. It only got worse as the slime’s hand expanded, and its thumb and pinkie wrapped around Fluttershy’s thighs, just before its palm began to slowly grind back and forth against the pegasus’s snatch. Trixie mimicked the action on her thigh, not quite willing to begin admitting just how hot this was yet.
Unfortunately, their top halves were doing nothing to help Trixie say no to the slime as she watched Fluttershy’s tits grind against the barely smaller mound’s of Sli. She could only imagine what the warm gelatin would feel like against her own bosom, and as her hand gripped her breast, she found herself wishing she didn’t have a bra on, or ever even owned a bra. A quick bit of magic later, and the clasp on her garment shattered. A quick pull left her bosom exposed, and a quick left forced a small moan from her body as she felt her erect nipples brush against the cotton that still covered them.
Opening her eyes back up proved to her that the slime was not out of tricks. Fluttershy was beginning to moan in ecstasy as the slime pulled away, and Trixie could clearly see that Sli’s own bosom had coated over Fluttershy’s. Small undulations in the light green ooze made Trixie realize just what the creature was doing. It was a full bosom massage that hit every point the thing wanted at once. The very idea sounded amazing, and soon, the buttons to her blouse were pinging against the walls, they came off so fast.
What made up Trixie’s thoughts on using the slime though was when Sli put Fluttershy on the ground. At this point, the hand that had teased Fluttershy’s sensitive folds was gone, and Trixie got to stare at both of theirs pursed pussies as they stared at her, before the slime kind of just melted into Fluttershy. Drop by drop, green goop splashed onto Fluttershy’s pussy and began moving, sliding along it. Trixie suspected it was akin what had happened to the beautiful mare’s bosom, and if that was the case... She couldn’t wait.
The hand on her thigh slowly crept upwards in an attempt to not get caught. Her own fingers touched her pussy as Fluttershy’s cries of ecstasy were all that could be heard in the room, and she bit into her lip as she finally touched herself. It wasn’t to be enough though, and she didn’t wait. Her pussy was already soaked, so she ripped her underwear off, before diving her fingers in.
What came next, Trixie could have never predicted. See, while she had been busy with her fantasies, her eyes shut as her fingers pushed in and out of her, Sli had noticed, and did not want to leave Flutters and hers guest unsatisfied. So, her hair had started fusing together, and using Fluttershy’s sweat to expand herself, the tendrils had snaked their way over, and now one pushed right below Trixie’s fingers, and right into the pink folds that so desperately needed her.
Trixie gasped at the intrusion, her mind freezing for a moment. She could feel the warm, gelatinous ooze snake into her, and while firm enough to stimulate her extremely well, it was soft enough to be gentler than any toy she had ever used. Her mouth opened wide as she felt another set of the tendrils snake over her body.
Two of them wrapped around her bosom, sending shivers through her body with each inch they covered. She somewhat hoped they would just collapse into ooze like what was happening with Flutters, but this was not the case. No, instead, her nipples got grabbed by the end of the tendrils, and she was yanked out of her chair by them. Her body stiffened at the force as her eyes felt like they were going to pop out of her skull, and heat within her pushed a wave out. Her juices could be heard splashing against the wood below her, but suspended in the air like this, one tentacle in her pussy while the ones on her heaving bosom were undulating soooo nicely, her hormones demanded once more.
Sli was glad to comply as another one of her tendrils pressed against Trixie’s mouth. The showmare didn’t resist, though at this point, she didn’t have much of a way to with how she was kept in the air by the being. The warm slime was sweet against Trixie’s tongue, and the mare let out a needy, hungry moan in response.
Sli turned to Fluttershy as she bit into her lip. The two had stopped a few moments ago, at Fluttershy’s behest, and with how loud Trixie was being, it was beginning to concern the slime. “I know that mares have limits. I mean, when we first tried this, I found yours, and it was a bit uncomfortable to see you pass out like that. So… maybe we should stop?”
Fluttershy turned to her friend, one of her hands fishing in a nearby bag for something. There was a new, yellow tint to her eyes, and Sli could barely hear the pegasus hum as she searched. “Oh, it’ll be fine. If she passes out, we can start back up later. I assure you, she’ll still thank you for the help.”
Sli bit into her lip for a moment, before her last tendril pushed itself deep into Trixie’s ass. She could see the mare’s eyes barely not roll all the way back, and breathed a sigh of relief. Even if Fluttershy let some deeper, more feral side of herself take control while she was in heat, Sli didn’t like pushing as hard as she did, even if she liked how happy it made Flutters.
The yellow mare laid back beside the slime, watching as juices poured out of Trixie’s nethers, and listened to the shouts of ecstasy that filled the room. Yes, she was happy to share her little secret to another, she thought as she lit the cigarettes she kept for this side of her. It let her have a new, fun toy to bat around with, and she couldn’t wait to see just how far the three of them could push their boundaries until the week for mating season was over.
