"Mistress Sunny highly recommended you, Ms. Sparkle. She said you would be an IDEAL sub for me. We'll see if she was correct," Mistress D said. Twilight said nothing, straightening herself up in the position she was in, as if it came naturally. She heard another chuckle from Mistress D, as her hoof steps approached. "While we're in this room, you are to address me as 'Mistress' or 'Mistress D', nothing else. Understood?" she asked, standing behind Twilight.

"Yes Mistress," Twilight said, keeping her breathing steady.

"I will not be referring to you as 'Ms. Sparkle' or 'Princess' from this point on. While you are in this room with me, you are my slave, and will be addressed as such. Understood?" Mistress D asked.

"Yes Mistress," Twilight said, taking a deep breath.

"Spread your legs for me," Mistress D said. Twilight did so, as Mistress D fastened some of the restraints on her hind legs. "Very well done so far, my obedient slave," she said, a smirk evident in her voice.

"Thank you, Mistress," Twilight said, sucking in a breath when she felt a strip leather of stroke her teats.

"Mmm. I'm going to enjoy pulling all of those moans and screams out of you, my little submissive," Mistress D said, tracing the tip of a crop on Twilight's nipples. The alicorn bit her lip, as the domme tortuously teased her hardened nipples with the crop. "You'll be a quivering mess when I'm done with you, begging me to let you cum. But, only with permission." She gave a sharp *SMACK* to Twilight's nipple in finality.

Twilight gasped. "Y-Yes Mistress!" Mistress D laughed, pulling the crop away, and coming behind Twilight again, restraining her forehooves behind her back. Reaching around, the domme stroked Twilight's dripping slit with the crop, causing the alicorn to buck with need. Mistress D tsked.

"Now now, my pet. We don't want you finishing too soon," she said, quickly pulling the crop away. Twilight whined, denied the pleasure she wanted, only to be met with a sharp pain. Mistress D had put clamps on her nipples, flicking them a few times, eliciting throaty moans from the sweating alicorn Princess. A small whirring sounded through the room, and soon, Twilight was seeing stars from feeling a powerful vibration on her clit.

"M-Mistress, please!" Twilight moaned, grinding her soaked pussy on the vibrating wand.

"Do you want to cum, my pet?" the domme pony asked.

"Yes Mistress! Please! Please may I cum?!" Twilight begged. Mistress D chuckled, as Twilight felt one of her hooves come to the back of her head.

"Prove it then, my little slave. Keep your mouth open and suck my cock like a good girl," she said, placing the fake rubber phallus on Twilight's face. Biting her lip, the alicorn slowly stroked her tongue up and down the shaft of the toy, hissing as Mistress D gave another *FLICK* to the clamps on Twilight's nipples. Steeling herself, the alicorn opened her mouth wider and slowly took the head of the fake cock into her mouth. "Mm. How eager. Good girl," Mistress D said, stroking Twilight's mane, as she pushed deeper into Twilight's throat. "Oh fuck yes. Mmm, I'm gonna fuck this tight throat of yours good, pet," she said, a grin evident in her voice. Twilight moaned in response, as her throat became adjusted to the size and width of the phallus, her tongue swirling around it. Instinct was winning out over inexperience for the lavender alicorn, as Mistress D pushed the rubber cock to the hilt in Twilight's throat. Letting the princess adjust to the sensation, Mistress D purred in Twilight's ear.

"Get ready, slut." Then, gripping the sides of Twilight's head, she pistoned the phallus into the alicorn's throat, savoring the choking and gagging sounds from the Princess of Friendship. Picking up the pace, Mistress D turned up the vibration of the wand placed under Twilight's pussy, sending out a muffled scream from her. Pushing deep into Twilight's throat, the domme kept her head in place, growling as Twilight struggled with tears stinging her eyes. "Stay still, little slave, unless you want me to punish you." Breathing through her snout, Twilight kept the cock in her throat for another three minutes, before being pulled back.

"M-Mistress, may I cum? Please? I can't take it!" Twilight begged, knowing that her tears were probably coming from the bottom of the sleep mask. Mistress D didn't answer, simply shut off the wand and pulled it away.

"Lay on your back, pet, and keep your legs open as wide as they can be," she said. Twilight nodded, falling to her side and then, with effort, managed to get on her back, with her hind legs arched up. "Good girl," Mistress D praised, flicking the clamps again, earning a moan from Twilight.

"Let's see how long you can hold out for, my little sub. You've done VERY well so far tonight." Gripping Twilight's haunches, Mistress D lowered her muzzle to Twilight's dripping cunny. "Tell me, my horny girl. Have you ever been eaten out before?"

"N-No, I haven't-A-AH! MISTRESS!!" Twilight squealed, as she felt the warm, wet tongue of the dominant pony slide up her slit. Another lick down and Twilight started seeing stars. Then Mistress D began rapidly licking Twilight's slit, and her outer lips, which she also gave a good tug with her teeth. Writhing and bucking, Twilight's tongue lolled out of her mouth. Mistress D chuckled.

"Stay with me, pretty girl. Just a little more then I'll let you cum for being such a good girl," she said.

"Uh-huh." Twilight mumbled, only to be returned to her senses when she felt a pair of teeth lightly bite on her clit. "OH! YES MISTRESS! THAT FELT SO GOOD!" With Mistress D's tongue buried in her pussy, and administering frequent flicks to the clamps on her nipples, Twilight approached the edge. "Mistress! Mistress, may I cum? Please Mistress? May I cum?"

"You need to cum, slave?" Mistress D growled, pulling back a bit and rubbing Twilight's pussy with her hoof.

"Yes Mistress! PLEASE!" she begged, her horn slowly starting to illuminate.

"I expect you to thank me when you do, slave. Understood?"

"Yes Mistress! I will! Please!"

"Go ahead and cum, slut," the domme growled, pulling back. With a scream, Twilight fell off the edge as her horn lit up.

"THANK YOU MISTRESS!" It felt like an eternity before she finally came back down, passing out from exhaustion.
Mistress D stood up and smiled.

"Good girl," she said, pulling off the sleep mask and removing the restraints from Twilight. Lifting up the alicorn and depositing her on the bed, she left a hoofwritten note on the nightstand and then headed out the door.

~o~0~o~

Her eyelids fluttering open, Twilight slowly sat up, nursing a crick in her neck. Her eyes adjusting, she found herself still in Mistress D's playroom, but the dominant pony was nowhere to be found. With shaky hooves, Twilight got to the floor, and stretched herself awake, finding the small piece of paper on the nightstand behind her.

I hope you enjoyed tonight, Princess. I certainly did. If you're interested in returning, I'd be happy to have you again.

-Mistress D

Twilight gulped, levitating the paper and folding it up. She'd never experienced something so..intense as what she did with Mistress D. The fact that she couldn't see her added to the intrigue. But, DID she want to come back? It had been risky just going to the club when she'd wanted to find Fluttershy, it'd be even MORE risky if she'd go back as a client. And yet, the more she thought about another session with Mistress D, the weaker in her legs she'd become. She could still feel the domme's hot breath in her ear. Shaking herself out of her reverie, and not wanting to stain the floors, Twilight headed out the door.

"Princess Twilight!" Viv called, trotting up to her. "Fluttershy is waiting outside for you. I told her I'd tell you when you were ready," she said.

"Thank you, Viv."

"Did you enjoy yourself, Princess?"

"Y-Yes, I did. Very much so," Twilight said with a blush. Viv smiled.

"Excellent. I do hope you'll come back again, Princess. It's been so long since I've seen Mistress D THIS gung ho about a pony," she said. Twilight's eyes widened, but only smiled in response, heading up to the main area of the club that was still bustling, but seemed to have died down a bit. She approached the exit where Fluttershy waited, in a red trenchcoat and pink scarf.

"Oh, Twilight. There you are. Ready to go?" she asked, her soft and timid tone returned. Twilight nodded, following beside her pegasus friend. "So...what did you think?" Fluttershy asked with a smirk. Twilight blushed, turning her gaze away. Fluttershy grinned. That was all the answer she needed.

Author's Note

Twilight's finished her first session. Now, it's back to Ponyville to sleep it off. Of course, that's assuming her dreams will be entirely innocent. A certain Princess of the Night is going to be very intrigued by the latest dreams of the lavender alicorn.
