Ten Questions: Hardcore Mode

Rainbow Dash woke up and stretched. She was sprawled out on her bed, covers pitched everywhere, and laying beside her—with his head stretched out and over her belly—was Thunderbolt.

It had been a special treat for Thunderbolt, and Rainbow Dash considered it well-earned. She had slept amazingly, peacefully, and all the way through to her alarm. Reaching one arm out, she slapped at the buzzing annoyance. Her own movement, however, drew Thunderbolt's attention.

Thunderbolt was well aware of his bitch, who he was quite aware was also his master. Before, he couldn't have compounded the two roles into one, but something had changed. Lifting his head up, he felt powerful, strong, and he knew Rainbow Dash would have to leave him. But first, he wanted something.

Squealing and squirming, Rainbow Dash tried to roll from he bed when Thunderbolt started licking at her groin. "St-Stop!" She hadn't told him the one word he would have understood, perhaps unconsciously so, and wasn't surprised when a big paw landed on her belly to pin her down.

"Ohhh…" Unable to extract herself, Rainbow Dash submitted to Thunderbolt. He licked at her folds at first, and she felt a burning heat that wasn't just her sexual need. Reaching a hand down, she started to rub at one of Thunderbolt's ear just as he pushed his tongue into her.

Losing any hope of using actual words, Rainbow Dash moaned hungrily at Thunderbolt. Clutching the covers in clenched fists, each stroke of his tongue was magic within her. She couldn't pull out from under his heavy paw, but she could push her hips up just a little, and widen her legs for him.

The gift Rainbow Dash had given Thunderbolt—her body—was not one he took lightly. With every lick he stole another sound from her throat, and it only emboldened him. Rainbow Dash's voice was music to him, and when he felt her start to peak he growled into her body.

With Thunderbolt's growl vibrating against her oversensitive body, Rainbow Dash screamed in impassioned bliss. He didn't let her squirm and thrash, but that only added to her delight. It felt like electricity—like magic itself—was pouring through her body as Rainbow Dash turned her head and clamped her teeth into the pillow.

Seeing his work as done, Thunderbolt jumped down from the bed and made his way through the house to the laundry. Dog food awaited, and after a relaxed meal and a drink of water, he made his way outside.

Of course his day was only just starting, and thanks to his memories of taking his bitch-master, he was rock hard and ready for the first regular bitch of the day. Strutting to the hole in the fence, Thunderbolt left to find relief.

With a morning greeting of such scale, Rainbow Dash dropped back asleep for a few minutes until the alarm went off again. "Alright, alright. I'm getting up." Climbing from her bed, Rainbow stretched her arms and wings out, finding simple delight in having her wings. "Shower, get dressed, then breakfast." She yawned and set off to take care of her tasks.

The shower was quick, and dressed in her normal clothes (her push-up bra was now part of her "normal" gear, as well as the scoop-necked shirt) Rainbow Dash was almost ready for the day. Opening her refrigerator, she opted to grab a yogurt tub and eat on the way.

Packing her bag light, Rainbow Dash made sure she had the little vibe she loved for taking the midday edge off her need, the study notes she had made, and her wallet. She stared at the things on the living room table, and grabbed the deodorant for her bag. "Just in case."

Her walk to school was slower than her bike would have gotten her there, slower even than if she had run, but it gave her time to eat her breakfast and slow her world back down. Things had moved fast over the last week: she had gained a boyfriend who wasn't, a lover, and had discovered more about herself and her friends. By the time she was at school, the magic of her morning wake up was gone, and she was back to her normal, human self.

"Oh! Hi Twilight." Rainbow Dash looked at the street before running across the road to meet up with her friend. She looked at Twilight Sparkle and realized the girl hadn't even heard her greeting.

Face down, looking at her phone, Twilight's thumbs poked at the keys quickly, pouring out her heart. A blue finger touched the top of her phone, and started her out of her message composition. "Rainbow Dash!"

"What's my favorite egg-head up to? Sending naughty messages?" The moment Rainbow Dash had asked her second question, she realized she had hit the nail right on the head. Her eyes widened at Twilight's blush. "You're kidding, who?"

"What do you mean, 'who'?" Clicking the lock button, Twilight jerked her phone back and shoved it into her bag before Rainbow Dash could grab it. "And what's with the cuffs, are you—" She froze, unable to finish the question as she realized the collar on Rainbow Dash's neck probably had something to do with it.

Twilight Sparkle had been on the internet, had searched for things an underage girl probably shouldn't, and had tried to piece together the way such things worked with her clever mind. She wanted to ask a hundred billion questions, but social norms pinned her down and she locked up. For five seconds. "Are those,"—Twilight grabbed for Rainbow Dash's wrist, catching it and examining the cuff—"leather? And there are fasteners on the… Are these locks?"

"Hey!" Rainbow Dash jerked her wrist back, blushed, then realized how stupid such a sentiment was. With a deep breath, Rainbow Dash got ready to deliver some truth. "Yeah, yeah. Look, I just like things like this, okay?"

In her head, Twilight Sparkle compiled a list of things to ask, not the least of which was what fetishes Rainbow Dash was into. "Abasiophilia? Acrotomophilia? Agalmatophilia? Wait, that one wouldn't work if you were tied up. Algolagnia? Andromi—"

"Twilight!" Rainbow Dash shoved a hand over her friend's mouth. "I don't know what half of those are, but you are not asking me anything about this at the front entrance of the school!" Grabbing Twilight's wrist, Rainbow Dash led the way into Canterlot High School.

Pulled along by her arm, Twilight Sparkle barely managed to keep up with Rainbow Dash, not that Rainbow was using any of her speed. Rainbow Dash dragged her up to the first floor, and along to the music room. Pulled inside, Twilight barely had time to process where they were before Rainbow Dash had the door closed. "So, does this mean you'll fill out a survey for me?"

"What? No!" Rainbow tilted her head up and sighed. "You can have ten questions, and make them good because there won't be any more." She knew her friend's insatiable appetite for knowledge, and so Rainbow Dash was offering Twilight the chance to sate her need without going too far. "And every question counts."

It was a tactic Rainbow Dash had used on Twilight Sparkle before, and Twilight was determined to keep to the rules and wring the most out of her friend. "What things are you into?"

"You want a list?" Rainbow waited until Twilight nodded. "Then get your pen and paper out. Right, bondage, dominance—"

Cutting in, Twilight winced at having to use a second question just for clarification, but it was important. "Top or bottom?"

Blushing only a little, Rainbow Dash knew the questions would be somewhat uncomfortable. "I'm a sub. That's two questions now."

"You didn't finish answering the first." Twilight's hand moved constantly, writing down what Rainbow Dash had said both verbatim and what she believed the girl meant.

"You interrupted, but sure. Bondage, dominance, a little exhibitionism—a surprise, I know—and I might have just found a thing for being treated like a guy, not sure about that. It's fun, though." At Twilight's wide eyes, Rainbow Dash grinned. It was easier when it was Twilight blushing. "What next?"

Rainbow Dash walked over to where her guitar was in its case, lifted it out, and started to strum slowly.

"Have you had penetrative sex? Uh, something going into you." Twilight wasn't aroused, but her desire for scientific exploration was.

Puffing out her push-up-bra enhanced chest, Rainbow Dash scoffed. "Pfft, of course."

If Twilight Sparkle was fully ponied up just then, she would have been wagging her tail in excitement. "So, penetrative sex with a guy?" Rainbow Dash nodded. "With a girl?" When Rainbow Dash nodded again, Twilight almost squealed. "So you are bisexual?"

"No. I'm straight as an arrow. That's six, by the way." Rainbow Dash's fingers danced over the strings, and the softest rendition of Awesome as I Wanna Be came from the unamplified guitar.

"Experimentation. Got it. That wasn't a question, by the way." Tapping her pen, Twilight focused on her last set of four questions. She looked down the list of answers so far, and though the figurative defeminization intrigued her, she wanted to know everything, and Rainbow Dash had sounded like that aspect had been something she hadn't explored much of.

"Describe what it feels like when a guy ejaculates inside you." Twilight pushed her glasses up, and looked over her notepad (which had suddenly risen to hide her blush).

"You're really pushing it, you know? And if you must know, I have not had a guy inside me. The only time I have been with a guy, he only put two parts of himself in me, and neither was his penis." The look on Twilight's face at her answer made Rainbow Dash's day. "Seven questions."

"That's not fair! You said you had had penetrative sex, and…" Trailing off, Twilight read her notes and saw how Rainbow Dash had qualified the answer. "What two parts of a guy have you had inside you? And where were they?"

"That's two questions." Waiting for Twilight to start to react, Rainbow Dash held up a placating hand. "It's okay, it can be one." Rainbow Dash had Twilight on the back foot, her friend was needing qualifiers on everything. "Finger and tongue, and both in my ass."

Twilight's hand froze for a second. She tried to force it to write, but until she got her brain un-kinked, it remained still. "Only finger and tongue, and in your ass." Excitement that she was getting to actually talk about sex with someone warred with Twilight's scientific curiosity. She wanted to ask another ten question just about how Rainbow dash felt about guys.

"All done? I don't mind stopping at eight." Reaching for another pick, Rainbow Dash swapped the little device with the one she had been holding.

"No, I just…" Twilight bit her bottom lip. "Can we just talk about guys after this, nothing specific, just as friends?"

Rainbow Dash had to stop strumming to bark a laugh. "That's nine, and yes."

Able to shove all the questions about being with guys to the side now, Twilight knew better than argue about the not-question; at best Rainbow would quote the rules of the little sparring match at her, at worst Twilight would ask another question by mistake. "Who was your experiment with? The girl, I mean."

With a shake of her head, Rainbow Dash sighed. It would have been so easy for her to finish the ten-question game right there, but she had too much respect for Rarity. "Not a question I will answer. She'll come out when she's good and ready. So you get one more."

Unfazed by Rainbow Dash's refusal, Twilight pushed on. "What did they do to you?"

"Indulging a little lesbian fantasy, Twilight?" Strumming through Better Than Ever, Rainbow Dash's fingers were nimble and loose, and she felt great thanks to Thunderbolt's morning wake-up. "She gave me a vibrator, and told me to put it in. She controlled it with a remote, and commanded me to do what she wanted. It was kinda fun, but I really didn't feel into it. If it was a guy…" She left the final thought unsaid, knowing full well that giving Spicy a remote for her vibrator was her thing, but not his. Fantasy never hurt, though.

Twilight closed her notepad carefully, stowing her pen inside. "And I suppose the normal payment will suffice?"

"Double chocolate-rainbow-twist sundae. After school at Sugarcube." Leaning backwards, Rainbow Dash lay her back on the little stage, and kept playing the guitar now laying across her lower belly. "Who were you texting?"

"Timber." Twilight felt she owed Rainbow Dash some honesty, particularly with how honest she had just been. "I had to apologize for what Pinkie Pie did, and for what I did. Pinkie was right, he thought I was eighteen."

Rainbow Dash turned her head to the side and looked at her friend. "So what are you doing now, waiting?" She watched Twilight nod. "He was pretty hunky. Although a little too smart for my tastes."

"What? No! Cute and smart is really hot." Twilight giggled, surprising herself at how good it was to be able to just talk with someone about Timber. "Did you see his butt?"

"Okay, I'll give you that. Those buns were pretty good." Something was different in Rainbow Dash's head: no matter how much she thought of Timber's ass, she found herself comparing it to Spicy's. Comparing, and losing. Her smile pulled a little wider.

Twilight, walking over to the mixing deck, flashed a look to Rainbow Dash. "So. This guy you're seeing. What is he like?"

For half a second Rainbow Dash was going to tell her friend that she wasn't seeing anyone, but Twilight had been honest, and it wasn't like Rainbow Dash had to name names. "Well, I don't want to brag or anything, but his ass is tighter than Timber's. Not as tall, though, but when he holds me I stay held."

Another ten questions shot to the fore of Twilight's mind. Rather than give in and start asking, she turned her attention to the board. Despite the description Rainbow Dash had given her, Twilight Sparkle found herself thinking about Timber Spruce again. "I like them tall."

Just then, the doors of the music room burst open. Fluttershy walked in first, and got nearly a full step inside the quieter-than-the-hall room before she froze. She stared at Rainbow Dash, and her memories showed her friend underneath Thunderbolt, with the dog rutting her.

Pinkie Pie and Sunset Shimmer were so caught up in looking at each other that they almost walked over the top of Fluttershy. Pinkie, her mane seeming to vibrate strangely, managed to stop herself just before shoving into their friend's back. "Look out!"

Sunset stumbled. The pink hands of her girlfriend shot out and grabbed hold of her, but it didn't stop her quick enough. On instinct, Sunset reached out to brace against Fluttershy's shoulder, and she grasped the girl's upper arm.

Time slowed, and Sunset was plunged into a wild, forested world of animals, but everywhere she walked there was a huge pair of amber eyes watching her. Suddenly she was pulled back and away from Fluttershy. Gasping as her mind was once more in her own body, Sunset was suddenly thankful that she didn't spend any more time in that strange place that was Fluttershy's head.

"Almost a whoopsy!" Pinkie Pie clutched Sunset against herself, and focused on holding her girlfriend out of her mind. Wrapping one arm around Sunset's midsection, Pinkie Pie looked instead to Fluttershy. "Are you alright?"

"Y-Y-Yes. Sorry." Fluttershy's pulse was racing. She felt scared in one of the few places she had never been scared before. She tried to withdraw, tried to pull back into herself and shroud her face with her hair, when a blue hand reached out to her.

Fluttershy's eyes trailed up from the blue hand, over a dark, leather wrist cuff, and up the attached arm to her friend. "Rainbow Dash!" The bright colors of her best friend's hair shoved all the fear away. Suddenly, Fluttershy could see the event for what it was: she had stopped in the doorway, and her friends had walked into her by mistake.

The blossoming smile on Fluttershy's face was all Rainbow Dash wanted to see right then. "Just breathe and relax. Remember our deal?" Fluttershy nodded to her. "I intend to keep it." She had made a promise when they were just children, that she would always be there for Fluttershy when she needed someone, and she had always kept it—except for when Sunset had been mean.

Forgiveness hadn't come easy, but Rainbow Dash considered Sunset having more than made up for what had happened. "How's Bridget?"

The loyalty and dedication in Rainbow Dash's eyes shoved back Fluttershy's anxiety even further. "She was really worked up this morning; I barely got out of bed."

"Thunderbolt was the same way. Although once he got me to—to uh,"—Rainbow Dash's eyes swept to their friends, who had left her to help Fluttershy—"Once that happened, he seemed happy to let me go. Oh, I totally meant to ask, did you work out what he turned into?"

Blushing, Fluttershy reflected for a moment how similar their mornings had been, and on that positive emotion continued. "I haven't, but it must be some kind of reptile. Does he feel cold to the touch?"

Casting her mind back only reminded Rainbow Dash of heat. Heat in Thunderbolt's tongue, his seed, and his belly. "Uh, nope. The opposite. He felt really hot." The moment she said it, Rainbow Dash broke into a silly grin. "Both ways."

"Howdy y'all!" Applejack slipped into the room. "Now we just gotta wait for Rarity, and we can all head down and face this together." Nerves had been creeping up on Applejack; she didn't have the raw smarts of some of her friends, but neither had she flitted away the year of study.
