Diving Head First

Twilight carefully opened the door to her study and slipped inside, levitating her kit bag and a basin of warm water behind her to set in front of the tied up daredevil. The sound of the lock sliding into place caused her heart rate to quicken as she committed herself past the reservations she felt. ‘It’s just a little hoof-i-cure’ the unicorn told herself. ‘It counts as a punishment because she doesn’t like other ponies touching her hooves. And besides, it … it doesn’t mean anything. It’s just a hoof-i-cure.’

It took Rainbow Dash a moment to realize what was in store for her. When she did the pegasus felt her eyes widen and her pupils contract as they focused on the damnable toiletries bag; drawing her hind legs up to her chest in effort to create some distance from it.

This didn’t bother Twilight, as she didn’t really need Rainbow Dash’s hooves to be in the water. Using her magic, she plucked the sponge from the water and reached it towards the mare’s hooves … only to have her move them away … then back … then forth … then down … and left. Twilight’s brow furrowed into a scowl in response to her friend’s deft dodging (which in turn elicited a sheepish grin from one feathered mare). But as the unicorn assessed the situation her expression softened as the glow of her horn grew just a hint brighter.

Rainbow Dash yelped as the librarian’s magical grip tugged on her multicolored tail, causing her to involuntarily buck her hooves down into the water with a small splash. ‘This is really happening,’ she thought. ‘She’s really going to do this, and there’s nothing I can do to stop her.’ However, there was something strange about this realization. In her mind Rainbow Dash knew she should feel some sense of despair, but what she actually felt was a bizarre sense of thrill. And it wasn’t all that different to the rush she got when speeding through the skies above Ponyville.

With her friend’s hooves submerged Twilight began scrubbing them clean, working the dirt out of the chips, scuffs, and scratches in her hooves. Once cleaned Twilight toweled them both dry and removed the basin before procuring the file.

Rainbow Dash swallowed and shut her eyes tight. ‘It’s okay,’ she told herself. ‘Calm down …. caalllm down. Just relax and don’t let it get you worked up.’

Although Twilight tried being as gentle as possible with the tool, every time she even touched it to a hoof Rainbow shied away. Once again becoming frustrated, this time the unicorn levitated a portion of the basin’s water and splashed it in Dash’s face.

The weather mare gasped and spluttered at the dousing and struggled against her restraints in a futile attempt to retreat from the sudden assault. As the, now cool, water ran in unpredictable paths down her fur coat Rainbow Dash couldn’t help but whimper in apology.

Twilight took the small towel in hoof and patted her charge’s cheeks neck and chest to a more comfortable dampness. To prevent any more defiant behavior, Twilight chose to lay herself across Rainbow’s hind legs, pinning them to the floor. She also noted that this added her body’s heat to that of her captive, which would assist in drying her damp coat. And with nothing left to stop her, Twilight levitated the file and dragged its rough edge against Rainbow’s hoof.

The pegasus shuddered and squirmed against the sensation that vibrated all the way up the inside of her leg. She fought to keep her breathing under control, but her heart hammered with such force in her chest it felt like she was punching Twilight in the shoulder. Much as she hated the sensation of another pony filing away at her hooves, a deeper, guilty side of her relished and desired it all the more.

The conflict inside combined with the numbing pleasure of Twilight’s expert hoof-care made Rainbow Dash’s head spin and fog up. After only a few moments it already became maddening. She couldn’t think, she could only feel. The warm press of Twilight’s fur rubbing against her own. The pull of the ropes on her fore-hooves that kept her bound in place. The Luna-be-damned file sending chills and shivers up her legs. All of these sensations transmitting to the inner reaches of her core nopony had ever touched before unknowingly being stimulated by the mare before her.

‘Oh, Celestia, have her finish soon,’ she prayed, ‘I don’t think … I … I can’t-’

“G-gguuhhh.”

The unsuppressed groan and shudder that then emanated from Rainbow’s throat and legs shocked the unicorn to the point where she nearly leaped away. Instead her head whipped around, unwittingly putting her nose to nose with the prismatic pegasus who was blushing furiously as she bit her lip.

The sight of this DID cause Twilight to leap away. “Did … D-d-did you … I-I-I’m sorry … I just … You … I didn’t …”

Rainbow Dash’s hazy mind fought to catch up and she stammered along with Twilight, trying to explain her way out. “I-I-I- … I didn’t- … It’s … I just …”

Embarrassed beyond belief, Twilight’s horn lit with a spell that cut the ropes binding Rainbow to the bookshelf. Having finally freed her friend Twilight turned and bolted from the study. Rainbow winced as the slamming door reverberated off of the study walls.

The silence that followed was crushing.

Still sitting in the place where she’d been bound, Rainbow looked around the room. It felt good to be free of her bindings but the idea of moving didn’t feel right, and not just because the mare was sure if she could even stand. Part of her wanted to go try to smooth things over with Twilight. Another part wanted to open the window and fly home with whatever false sense of dignity remained. But the part that won out had her curl up there on the floor and wait for Twilight’s return.

It was a tear-filled wait that would last on into the morning.
