Rainbow Dash would never quite be sure what lead her here but here she was standing on Thunder Mist's front steps again, the setting sun warm on her back while the chill of the night breezed through her coat from the wind, but if she had to guess she'd have to say it was Pinkie Pie, Pinkie Pie had got her thinking, and thinking got her to doing and then she was here.

She had only gone to Sugarcube corner to buy a snack, something to ease the sweet tooth she had, next thing she knew she was swept up in a whirl of pink simply known as Pinkie Pie.

"Did you know Thunder was single?" she had said with an odd gleam in her eyes, which usually wasn't a surprise considering who was speaking but her next word knocked the breath from Rainbow's lungs.

"You could probably ask her out you know? She likes mares and stallions" Pinkie continued before Rainbow could even get a word in edge wise not that Rainbow was able to say anything after that comment.

Rainbow had tried her best since that day to deny she was interested in mares in the slightest and that she wasn't interested in dating...but here she was anyway, cause what Pinkie said had made her curious, nothing more, she knew she wasn't gay, so what if she spent a little time watching a mare's flank more than she should it didn't mean she was gay...did it?

She had been pushed to Thunder's house by an excited Pinkie Pie, who quickly disappeared in ways that can only be considered 'Pinkie Pie', and her own curiosity and knocked, the dark blue mare answered the door rather quickly and allowed the cyan mare into her house curious of her unexpected visit...

That was how this all started, and now every few days she'd find herself her on these same steps standing before this same door wondering why she was here swearing this would be the last time, wanting to leave but not wanting to go. She knocked on the door as the stars began to appear, wondering if Luna knew what she and her daughter were doing under her moon.

Thunder opened the door with a friendly grin "Hey Rainbow, come on in, Red's having a sleep over with the Cutie Mark Crusaders so we'll have the place to ourselves for the night, are you hungry I have some leftovers if you'd like them" she let Rainbow out of the entryway closing the door and making sure it was locked before following. Their 'arrangement' had a few rules:

1) they were not to mention it to any other pony or make it seem like they were dating

2) they were not to doing what Rainbow called 'dating stuff' so that meant that they weren't allowed to eat romantic food or in any sort of romantic way if they even decided to have food at all

3) they weren't allowed to bring 'mushy stuff' into it.

Thankfully Thunder didn't seem to mind, she always made sure that if she did have leftovers to share with Rainbow Dash it was usual just a fruit salad or a dandelion sandwich, nothing romantic at all. But Rainbow wasn't hungry and told her so, her previous anxiety and confusion melting away in the dimly lit house, instead a different sort of feeling grew in her stomach. She walked toward Thunder pulling her close until their muzzles touched. Rainbow desperately kissed her lips as possible. Thunder giggled under the onslaught, kissing back as deeply as she could so that Rainbow found herself grinning as she worked, tugging on her lower lip before tugging the other mare up the stairs toward her bedroom.

This was why she kept coming back Rainbow realized, this wild abandon and control, she couldn't find it anywhere else sure she might've found something like this with Fluttershy but Fluttershy wasn't quite right, she was to...well shy Rainbow wanted control sure but she liked the fight a bit more. The pair managed to make it the bed even with the shades drawn on the windows, having taken this path a few times already, even as their tongues fought for dominance. Rainbow won in the end however pinning down the other mare with a cocky grin before diving in once again kissing her lips again a bit of a purr in her throat.

Thunder moaned into the kiss gasping a little as Rainbow nipped at her lip, Rainbow had always been a bit dominating but Thunder didn't mind even preferring it a bit. She was a bit anxious at time but she didn't like it when people treated her like she was made of glass, her parents doing it was one thing, but Rainbow didn't, she was rough sometimes even leaving bruises on her coat and Thunder couldn't be happier well most of time...

Lately Thunder had been thinking about their arrangement, she liked it but part of her wanted something more with the cyan mare but she never dared to bring it up, she knew Rainbow would never go for anything more than what they had it wasn't 'cool' to be a fillyfooler and Thunder didn't want to upset her, but trying to reel in her thoughts and feelings was starting to get harder with every visit.

"You feeling alright?" Rainbow questioned her breath coming out in quick puffs her eyes dark with lust, she had been nipping at her neck when she had felt Thunder stiffen, usually she didn't think much of it but Thunder was silent, never a good sign.

"...Yeah I was thinking about what we should use this time" Thunder replied quickly giving Rainbow her best attempt at a smile she didn't want Rainbow to get uncomfortable then she might leave. Thunder shifted picking out on of their accessories picking out one of their favorites, a double sided red dildo with black strapping chuckling when she heard Rainbow's moan of arousal knowing that, at least for now, her lapse in behavior was forgotten.

Rainbow licked her lips a little “Get ready” she husked out softly and Thunder nodded and turned knowing what was to come and feeling a tingle of excitement run up her spine at the same time that disappointment sank in her stomach like a stone. Wanton lust shaking her limbs, Rainbow slipped on their choice for the night shivering a little as the dildo slid into her damp core. Balancing on her knees and adjusting the device until it fit just right.

Rainbow Dash swallowed the salvia pooling in the back of her mouth as she looked at her companion dropping forward and wrapped her front legs around Thunder’s middle section, taking the stallion position in their pairing, she gripped her firmly and closing her eyes Rainbow started moving her hips against Thunder's rear thrusting the toy in and out.

Thunder moaned as Rainbow starting thrusting in earnest. Rainbow’s face was buried in Thunder’s mane and she bit and kissed anywhere she could reach, feeling her own body tingle wherever the pair were connected. Was this a normal feeling? She wasn't sure, but lately she had been feeling it more and more What did it mean? Desperate to leave those odd thoughts behind she began to speed up her thrusts, resulting in a wet smack every time their bodies connected.

“Oh, R-Rainbow....Oh yes!” Thunder moaned, rocking back to meet each thrust she felt their combined lust run down her legs. Rainbow tightened her grip and one of her hooves slid back to rub at Thunder’s clit. Thunder felt her orgasm approaching like fire rippling through her coat and desperately willed it away, not wanting it to end but there was nothing that could stop the force of her release.

Rainbow felt Thunder tense beneath her, arching in her grip as she cried out in a hoarse groan leaning back into Rainbow's grip waiting for the trembling to stop. Rainbow gasped air into her lungs as she continued to rut her hips the scent and sound of her partner enjoying her attentions make her heart race a little faster the strange feeling returning as Rainbow felt herself hit her own peak, she buried her face into Thunder's black and white mane to muffle the noise she made as her lust spilled free.

The pair fell onto the sheet on their sides each panting to try and catch their breath Rainbow yawned, pulling a gently snoring Thunder into her chest her mind in a haze as the afterglow of their orgasms tingled through their limbs, at the moment she didn't care about her odd thoughts or what they meant, she was to tired to bother with them they didn't seem all that bad, she kind of liked the tingly feeling that they gave her. Only one thought floated through her mind before sleep overtook her: Maybe they aren't to bad...
