Twilight stared at the recently compiled list of kinks she’d drawn up for herself. The first two she’d already scratched off. Making a miniature clone. Check. Making a miniature clone of the Princess. Check. Eating the miniature clone of the princess. Check. Experiencing nearly traumatizing nightmares. Check. Spanking. Twilight stared at the list, ignoring the next couple of items on the list.

She’d always wondered why some ponies found being spanked to be so… kinky. When she was a filly, getting spanked meant she was in trouble. She just couldn’t wrap her head around how being spanked could be considered kinky. However, she couldn’t just have anypony spank her. It certainly couldn’t be her own parents. Any random stallion was out of the question as well. Sitting at her desk, pondering the problem, an idea struck her.

Rainbow Dash.

The mare was always bragging about her sexual exploits when they weren’t out in public. During the frequent slumber parties they’d all started to have, Dash had taken to bragging, regularly, about how often she had sex. Maybe she’d be up for it. Looking out the window, she watched the skies for a tell-tale rainbow-colored trail. Spotting the end of one, she followed it to its source, homed in on it, and cast.

Her magic snagged like a fishing lure. She smiled as the blue pegasus with rainbow locks froze in place. Pulling Rainbow to the castle, she spun the pegasus around and smiled.

“Oh. Hey Twi. What’s up? Did you need me for something?” Rainbow asked and Twilight smiled and pulled her into the castle.

“I do actually. You’re always bragging about how much sex you have. I want you to help me with something,” Twilight said as she set Rainbow on the floor and walked over to her new chest. Starlight had affectionately called it her “toy chest”.

“Oook. What do you want me to help you…” the question died on Rainbow’s lips as Twilight pulled out the leather collar, wing straps and barding. Along with them came a matching pair of plugs, a rubber bit, and a riding crop. “Uh… T-Twi… what are you doing with those?” Rainbow asked and Twilight just smiled as she held still. Her magic moved everything into place.

The wing straps tied her wings down against her sides just as the leather saddle blanket went over her back and under her wings. Once in place, she stepped into the fishnet stockings and pulled them up before clipping them to the blanket, so they stayed up. Rainbow merely watched as Twilight put the bit in her mouth and tied it on with her magic. Looking around, Rainbow noticed her magically inclined flying friend had thought ahead. There was a small white board and a marker sitting on the nearby bed.

With the bit in her mouth, Twilight floated the white board and marker over and wrote on it. She spent some time, even erasing parts, before passing it to Rainbow.

“I’m experimenting with kinks so I can learn why some ponies have them and I need help with this one. The Bondage Kink. I don’t have a special somepony to try this with and you’re always saying you’ve done everything. I thought who better to try this with than someone who knows what they’re doing,” Rainbow read aloud before looking at Twilight. The white board floated back over to Twilight, who erased the message, wrote a new one, and passed it back. “Did I put all the straps on right?”

Rainbow sat still for a moment, her mind reeling. On the one hoof, Twilight was a bombshell. She had that adorable sexy nerd charm going for her. She was an Alicorn, which seemed to just magically make her sexier. Rainbow would openly admit that she’d had a few naughty thoughts here and there about Twilight. Seeing her trussed up in leather with a leather bit in her mouth, two plugs and a riding crop made Rainbow’s feathers twitch.

“Alright Twilight. You wanna experiment with this. We’re gonna set some ground rules first,” Rainbow stood up and walked over to Twilight, taking the bit out of her mouth. “First, while we’re doing this, you’re my pet and I’m your owner. You won’t use my name, you’ll just say ‘Yes ma’am’ or ‘yes master’, clear?”

“Yes ma’am,” Twilight said.

“Good. Second, I’m not gonna take it easy on you. I’m only gonna stop if you start cryin’,” Rainbow said and Twilight stared at her for a minute, as if she was confused. “We’re friends Twi. I’m not gonna do anything that’ll actually hurt ya,”

“Would that ruin the experience?” Twilight asked and Rainbow paused for a minute.

“Well… no. But this isn’t about masochism. This is a bondage thing. You’re not supposed to hurt. It’s… It’s about not being able to do anything to help the experience along,”

“Oh. So it’s like a deprivation thing,” Twilight said, and Rainbow nodded.

“Yeah, basically. Oh, we’re gonna need a safe word. Something you wouldn’t normally say in conversation. Uhm… how about something that makes you uncomfortable?”

“Snakes.” Twilight said quickly. The instant response almost shocked Rainbow.

“Snakes. Ok, got it. The safe word is snakes. If I start to do something you don’t like, you say snakes and I’ll stop. The whole session will stop. Deal?”

“Deal.” The two mares nodded, and Rainbow put the bit back in Twilight’s mouth.

“Oh, one more thing. To get the full experience, I’m gonna call you things I don’t usually call you, ok? I don’t mean them to be hurtful, it’s part of the experience,” Twilight nodded, and Rainbow moved away from her friend for a minute. If she was going to do this, she needed to get out of the mind set of “this is my friend” and into a mindset more akin to “this is my toy to play with”.

For Twilight, time seemed to stand still. The blindfold was designed to keep all light from reaching her eyes. For all intents and purposes, she was completely in the dark. She could hear, smell and taste just fine, but she couldn’t see. She had no idea where Rainbow had gone. Suddenly, a leash was attached to the collar, and she was forced over onto her chest.

Rump in the air, Twilight fought the urge to hide herself with her tail. As much as she could at least. Her tail rapidly came down between her cheeks. Just as quickly it went back up as the leather crop wrapped across her hind quarters. “You can only hide yourself if I say you can, slut!” Rainbow shouted, her voice sounding like it was miles away. She was flying. She’d kept herself off of the ground so it would be a surprise where she was.

Twilight kept her tail up now. That had hurt, but she wasn’t done. She knew Rainbow had more in store for her.

A drizzle of cold liquid on her ponut made her shiver. That earned her another wrap from the crop. She couldn’t cry out with the bit in her mouth, but she could feel her tears starting to flow. “Hold still!” Rainbow shouted from directly behind her. Twilight held as still as she could as Rainbow’s hind hooves pushed her own apart. What was she planning?

A slight pressure against her ponut alerted her. Squeezing her eyes closed, Twilight held as still as she could as Rainbow pushed something into her rear. It was narrow at first, a blunt point pushing her hole open, but it widened and thickened before it popped into her. The plug. The short plug. A gentler smack form the crop, this time against her sex. A reward? “Good pet. Took that like a real pro.” Rainbow said in her ear and Twilight shivered.

It felt nice being praised like that. “If you behave until we’re done, I’ll give you a treat.” Rainbow said and Twilight felt something touch her muzzle. It was warm and wet and smelled faintly of oil. Did Rainbow have a strap on? She couldn’t open her mouth to let it in with the bit in her mouth, but that didn’t seem to be Rainbow’s intention. Twilight didn’t get to have her treat yet.

Silence was Twilight’s only companion for a moment. Rainbow was still flying around her. The gentle wing flaps were unmistakable, but they seemed to be moving around the room. Was she looking for more toys to play with? “Whoa. This is cool. This could be fun.” Rainbow’s voice said from Twilight’s right. Her desk. Had Rainbow found something at her desk?

“Lift your rump higher pet,” Rainbow was next to her again. Pet seemed to be the nickname when she was good. Slut was reserved for misbehavior. Twilight did as she was told to the best of her ability, lifting her rump higher into the air. Her tail tickled her back as it fell limp over her shoulders. “Good. Now stay,” Holding the pose was tough. Twilight wasn’t nearly as flexible as Rainbow or Pinkie or any of her other friends.

Suddenly a cold ring pressed against her thighs, pushing between them to rest against her labia. She shivered but it didn’t earn a smack from the whip. She heard tapping, what sounded like leather on glass, and something fell against her slit. “Flex your slit pet. Open it up,” Rainbow ordered, and Twilight tried to widen her stance. She got a whip to the ponut for her effort. “No! Your slit, slut. Use your muscles. Open your slit!” Rainbow shouted and Twilight closed her eyes under the blindfold.

She concentrated on those muscles. Normally she couldn’t flex them unless her heat was on her, but she had to listen to her master. She felt the muscles move and knew she’d succeeded when something fell into her waiting hole. She hadn’t been ordered to close though, so she kept her slit flexed open. A sudden pressure and the cold thing that was on her labia was pushed into her folds.

She yelped as much as she could around the bit as it was pushed almost completely into her. She could feel something else further inside her, however. She wasn’t sure what it was. Suddenly the cold thing was pulled out of her, and Rainbow pushed her thighs together. A silent command. She obeyed and closed her hips, her slit clamping closed around whatever it was inside her. Now she could feel it. It felt like another pony. Her eyes went wide under the blind fold, and she mumbled under the bit.

She heard something slid in front of her and groped with her magic. When she finally found the pen. “SNAKES” She was sure she’d written that. Her horn writing was good, but she’d never written something blind folded before. The blindfold came off and she was grateful to see she had written a slightly legible “snakes” on the white board. Rainbow took the bit off and Twilight immediately rolled onto her back and looked at her belly. Her belly moved and pulsed as if something was pushing against it from the inside.

“What is…?”

“Oh that? I found a jar on your desk with a little mini version of you in it. Thought it might be fun to put her in you, see what happens. I mean… you didn’t mean to make a small clone of yourself, did you?” Rainbow asked and Twilight just stared at her belly. She’d need something to get herself out of the sticky situation she was in.
