Intensive Training

The room was a mess. Clothes, sex toys, crops and cuffs were strewn across the floor and over knocked-askew furniture, the tangled debris of a magnificent fucksplosion. Rainbow and Spitfire lay amidst it all, lithely muscled bodies nude and coated in sweat, panting for breath. Too hot to embrace, Rainbow reached out and linked her fingers with Spitfire's, pushing her damp, tousled mane from her eyes.

"...new record," she panted. "You win."

"You win, Commander," corrected Spitfire, squeezing Dash's fingers. "We're not done until I say we're done. Speak impertinently to me, and you'll earn another demerit."

Rainbow's free hand flew to her neck, touching the collar still tightly buckled around her throat. "Oh Celestia, please have mercy, Commander," she pleaded. "My ass can't take it!"

Spitfire gave a husky giggle, rolling over onto her stomach. Running her hand over Rainbow's reddened ass, marked with the stripes of a paddle, she teased, "And that's why you're a raw recruit."

Stifling a whimper as the other mare's fingers traced a heart-shaped welt, Rainbow murmured, "Not an actual recruit anymore- ahh! Commander! I was totally going to say Commander!"

Wriggling her fingers to ease the sting from her palm, Spitfire pulled herself a little closer and kissed Rainbow's small, firm ass where she'd smacked it. "There. Don't say I'm not a merciful superior."

"...thank you, Ma'am," Rainbow breathed.

Laying her fiery head against the back of Rainbow's thighs like a pillow, Spitfire sighed comfortably. "Alright, alright. You are now off-duty. I'll get your collar in a minute."

Rainbow relaxed, her bound wings shifting position slightly against her back. "Seriously. I fucking love this, 'fire."

"Don't know how you talked me into it," Spitfire replied teasingly, lazily running a fingernail along Rainbow's pale blue thigh. "It's been what, a year now?"

"I talked you into it the first time. The rest was all you," Rainbow objected mildly, shivering as goosebumps rose in the wake of Spitfire's nail on her tender skin.

"I work hard to be the best at everything I do. Including you."

Rainbow started to say something, then stopped.

Spitfire raised an eyebrow, lifting her head slightly. It wasn't like the other mare to hesitate. Brash as a battering ram, as to the point as an arrow, the only thing faster than Rainbow was her mouth. "Yes? What is it?"

"So, we're not exclusive, that was the deal."

"...yes?"

"Uh. Are you... doing this with anypony else?"

Spitfire frowned thoughtfully at the back of Rainbow's head. Was her lover getting jealous? If so... well, maybe she could think about going solo with Rainbow. It wasn't like the multihued mare didn't have enough energy to keep them both busy. "I screw other mares now and then. I haven't done any of this-" she gestured loosely around them at the scattered restraints and instruments of pleasurable punishment, "-with anypony else. That's all you. Why?"

"...do you wanna?"

There was a subtly yearning tone in Rainbow's voice that took Spitfire by surprise. "...I could," she allowed, not completely sure where the conversation was going. "Why, you got somepony in mind?"

Rainbow's wings tried to fluff outwards against the bands, betraying a little quiver of arousal. "...uh huh," she murmured. "Been hinting about what we do together to a pony I know, and I think she's interested. She sure couldn't take her eyes off you, last time we were together."

Huh. Admittedly, the idea did have a certain appeal... another cute little pony to bind and tease could be a lot of fun. "Who is this mare?" Spitfire asked, already running through a mental roster of the Wonderbolts Rainbow seemed closest to. Cloudchaser? Flitter?

"Uh." Rainbow paused. "...Applejack."

Spitfire blinked, pushing herself up on one elbow. "Applejack?" she echoed dumbly.

"I mean... yeah. Her." Rainbow was hiding under her untidy mane, but Spitfire knew her well enough to tell when she was blushing.

"An earth pony? I've never... how do you even screw without any wingplay?" Spitfire asked, a little dumbfounded. She'd only paid polite interest to Rainbow's friends in the past, refusing to be intimidated by the whole 'saviours of Equestria' thing, and the picture that formed in her head was blunt, good-natured self-confidence in a Stetson. Detail was lacking. Shaking her head, she added quickly, "Not that that'd be a problem. Applejack. Seriously?"

"Uh huh," Rainbow murmured again. Swallowing, she added, "If you trained her, then maybe once she's used to it, you could... train us together?"

Squeezing Rainbow's tender ass, Spitfire looked down at her lover. "Like that idea, do you, recruit?"

"Y-yes, Commander!" Rainbow agreed hoarsely.

"...okay. Look. I'm not against it. But I am not going to be the one to introduce the idea to her, you got that? Sit down with her, have a frank talk about the whole thing, and then if she's interested, I'll give her a try."

"Yes, Ma'am!" agreed Rainbow quickly, nodding and looking back over her shoulder. "I'll talk to her tomorrow."

"You better." Allowing herself to become intrigued by the thought - an earth pony? - Spitfire looked back down at Rainbow, and picked up a double-ended dildo from amongst the sexy debris. "You know what? You're still in the collar. Report for duty."

"Reporting for duty, Commander!" Rainbow answered urgently, her body tensing.

"Good."
