Sunset Shimmer went into the Principal's office, taking a seat in front of the desk. "You wanted to see me, Principal Celestia?"

"Yes," Celestia answered, sitting on the desk with her legs crossed. "I did." Sunset wasn't sure, and it would have been awkward to ask, but she was sure Celestia was wearing a lower-cut shirt than she usually did.

Sunset turned her head from left to right, searching the room. "Um ... shouldn't you be sitting behind the desk?" Sunset asked, raising an eyebrow.

"Ordinarily, yes. But these are special circumstances." Celestia reached down into her shirt, pulling out a letter out from her cleavage. Sunset's eyes tracked her hand, but she found it difficult to take her eyes off Celestia's cleavage, a fog creeping into her mind.

"Uh ..." Sunset groaned, putting a hand on her head.

"I've been reviewing your accounts, and I found that you still haven't fully paid off the debt to the school for blowing off the roof that one time ..." Celestia said. "But if you were to do some certain things for me, I might be willing to cover the difference for you."

"What!? But I - I repaired it myself! Brick by brick!"

Celestia chuckled and waved her hand. "Ah, Sunset, I'm just messing with you. I think you kids call it 'trolling,' these days? Anyways ... recently, I had a talk with Twilight Sparkle. I noticed she had been coming in ... unusually sweaty on Mondays, and when I asked her why, she was secretive. I had to press her for details ... and she wrote me this letter. And I have got to know if anything she wrote in here is true."

"You can't just ask her again? Or ask Rainbow Dash or someone else she knows?" Sunset asked.

"I ... could, maybe." Celestia said. She cleared her throat. "But I wanted to see this myself, hands-on for ... private reasons."

"Uh-huh." Sunset crossed her arms, not sure what those reasons could be or if she cared to know them.

Celestia unbuttoned her coat and shook it off.

"Uh ... Principal, what are you doing?"

Celestia flashed a smile at her, then pulled up her shirt, taking it off over her head and flinging to the side of the room, where Sunset could see her ample chest, clad inside a white brassiere.

"C-Celestia ..." Sunset stuttered, the spell beginning to take a proper hold. "Y-your che-che ... boobs ... "

"Yes?" Celestia asked with coyness, putting her arms together to squeeze her breasts.

Sunset hesitated, but went on. " ... they're beautiful."

"I thought you might say that." Celestia cupped her chin. "So it is true. Here." Celestia unhooked her bra and tossed it to Sunset, who caught it in her hands. "Enjoy that for a minute, would you?"

Sunset closed her eyes and lifted the garment up to her nose, where she took in a deep breath to enjoy the scent of Celestia's flesh on it. She groaned and tossed the cloth to the floor. "I don't care about your stupid foreplay! I ... I want ..." Sunset reached her hand toward Celestia's breast, her eyes drawn to Celestia's nipple and being rendered unable to finish a complete thought.

"Do you want to play with my nice round boobies, Sunset?"

"Y-yes ..."

"Do you want to suck them? You're more than welcome to."

Sunset stood up and walked over to the desk.

"I want to suck them - I need to suck them." Sunset reached her hands toward Celestia's chest. "Ooh, do you have any milk in them? Big beautiful milk jugs like yours just aren't right without any milk in them!"

Celestia raised an eyebrow. "Twilight really did a number on your head, huh?" Despite being off-put for a moment, Celestia smiled and continued her seduction. "But to answer your question ... why don't you suck them and find out?"

Sunset reached down and wrapped her lips around Celestia's left breast, biting and sucking on it. As she nursed, Celestia ran her hand through Sunset's hair.

"Ooof! I can't believe I didn't do this sooner. It's been a while since I had a lover who handles me as firmly as you do, Sunset." Celestia held up the letter and waved it around. "According to this letter, you like it when your Mistresses talk up their boobs for you to suck. And you also like it when we call you our good little boob slave. Is that true?"

Sunset popped her mouth off to answer. "Yes! I like - I love being called a good little boob slave. It's what I am!" Sunset's cheeks flushed pink. "Whenever I see gorgeous jug like this one," Sunset reached over and groped Celestia's other breast, "all I can think is how much I want to suck it! How good and soft it would feel in my mouth ..." Sunset let out a little bit of drool, which dripped onto Celestia's bust. Celestia smiled and admired her on-loan boob slave.

The door opened. Luna came in, holding up a folder. "Celestia, I have those files you wanted - woof."

"Luna, come in, come in." Celestia gestured Luna over, even though Sunset found it awkward. "Sunset here was just telling me how much she looooves to suck big boobies. Especially ones like mine, right?" Celestia cupped herself and jiggled her breast up and down.

"Yessss ..." Sunset hissed.

"Hmm." Luna said. "Well, I didn't believe the contents of that letter at first ... and when you offered to invite me in to join you, I thought you were joking about this." Luna placed the folder down and cleared her throat. "But, uh ... now that I am here ... is that offer still open?"

"Of course." Celestia said. "As long as Sunset doesn't mind. You don't, do you, Sunset?"

"Not at all, Mistress." Sunset said.

Luna took her shirt off, letting her chest spill out, which made Sunset lick her lips in anticipation.

"Of course, now that you're here, I may want to shake things up a bit ..." Celestia said. She lifted Sunset up and carried her over to the chair, placing there. Luna walked around the chest and drew her finger across Sunset's chin.

"Open up." Luna said, before taking off her brassiere and inserting her nipple into Sunset's mouth. Sunset suckled it obediently, with a half-lidded expression.

"Mmm!" Sunset moaned as the familiar sweet taste dropped on her tongue. While Celestia was still open to debate, Luna's breasts definitely had the milk she craved. She nursed Luna's teat more desperately after that.

Sunset didn't notice Celestia getting to the floor, placing her hands on Sunset's thighs and pulling down her skirt. Celestia licked her lips to moisten them up before giving Sunset a kiss down there, sending a buzz through Sunset's spine.

"Mmmmh!" Sunset's eyes rolled back. She continued to drink up Luna's milk while Celestia suckled and nursed her down there. Sunset began bucking in her seat, kicking up her legs and wrapped them around Celestia's neck.

"MMMMH!"

"MMMMH!"

Sunset tilted back, continuing to suck Luna's breast for milk even while she had her orgasm, letting a torrent of nectar loose into Celestia's mouth. Celestia gulped and drank it down with all the same eagerness Sunset had for Luna's milk, a lump forming in her throat.

"Aaaah ..." Celestia pulled away, feeling more than satisfied.

The realization of what she had just done causes Sunset to stop her sucking so she could take a moment to process what just happened. She grabbed Luna's breast and pushed it out of her mouth.

"Did ... did I just orgasm into the Principal's mouth?"

"Indeed you did." Celestia let out a pant. "And I'm glad you did. Sunset, has anyone told you have ... absolutely scrumptious nectar?"

Sunset rolled her eyes. "So I keep being told ..."

"Well," Luna glanced up at the clock, "as much as this has been fun, I think we'd better wrap this up. There are still school duties for us to attend."

"Right." Celestia stood up. "Sunset, open up extra wide for this one, okay?"

"What do you mean extra-"

Celestia and Luna pressed up against each other, pushing the sides of their boobs together, and shoved both of themselves into Sunset's mouth. Sunset's eyes went wide, but she nonetheless sucked both of their nipples like the good little boob slave she was. And Celestia's breast apparently found it time to quit holding back, spurting milk into Sunset.

"Mmmmmmm!" Sunset moaned sharply, milk spilling down the sides of her mouth. She sucked harder, her tongue trilling as she filled with delicious milk ...

"Mmm ...? Mmm! Mmm!" Sunset moaned in confusion as she felt it a bit odd, but it only encouraged to bite down on their breasts harder and suck more. Their breasts tasted so good ... their milk tasted wonderful. It was so sweet and rich and creamy and warm and it was filling her up, bringing all of those delicious traits into her stomach. Sunset felt like a candy getting injected some fresh, hot filling ...

"PFFTMMMM!"

Sunset kicked her legs out, striking her shoes against the desk, using it to hold her steady. Celestia watched a satisfied smile as dark spots appeared in Sunset's skirt, her second orgasm dripping and staining her clothes.

Celestia turned to Luna. "I think that's enough."

Luna followed Celestia in taking their breasts out of Sunset's mouth, both of which escaped Sunset's lips with a loud pop. Milk continued to dribble down Sunset's chin, her body still thrashing in the throes of pleasure until her orgasm died down, leaving her with a very stained skirt.

"Luna and I have to get back to work." Celestia cupped Sunset's chin. "But if you ever want to experience that again, just give me a call and swing by my office after hours, and I will feed you ..." Celestia, despite saying they had done enough, squeezed her boob, spurting milk onto Sunset's face. "All the adult milk you want. I imagine it's a bit brewed than Twilight's is, hoo hoo!"

Celestia and Luna went and got themselves dressed, clipping their brassieres and putting their shirts back on.

"You take as long as you like to rest here until you think you can stand up without falling over. But not too long, because I might try this again if you're still here when I get back ..." Celestia pulled the door shut.

Sunset, stubborn as she was, tried to get to her feet. She was unsteady and fell down to the floor, still feeling the milk drip down her body.

"I guess I'll just ... lay in the floor for awhile."

A few weeks later, Twilight and Adagio were enjoying their weekend nighttime fun with Sunset, lying on the bed, their magically-enhanced breasts leaking out milk.

Adagio adjusted herself, resting her head on her hand. "You know, Twilight ..."

"Yes, Adagio?"

"We've made Sunset suckle me, you, and even deigned to share her with Luna and Celestia ..." Adagio counted off on her fingers. "But you know who we haven't made her suckle?"

"Who?"

"Herself." Adagio answered with a smirk.

"Uh, well, technically speaking ..."

"Bup bup bup, I don't care for your technicalities." Adagio tapped her necklace. She waved a glowing hand over Sunset's bare chest, making her breasts swell up to the size of basketballs.

Twilight grinned. She got up from the bed and pulled out a hand mirror. "Sunset, sit up."

"Huh?" Sunset groaned, following Twilight's command. She looked into the mirror and her eyes widened at the sight of her enhanced cleavage. She licked her lips before grabbing one of her breasts and lifting it up to her mouth, beginning to suckle and nurse it. She laid back on the bed, continuing to pleasure herself.

"Hmm." Twilight mused. Of all the ways they could have fun with Sunset, using the trigger to make her love on her own breasts hadn't been something Twilight had considered.

"She still looks so cute when she's suckling, doesn't she?" Adagio asked.

"Yeah ..." Twilight replied, smiling. The two of them laid there and watched Sunset go to work on herself, suckling her own boob until it made her toes curl up, reaching orgasm and ruining yet another one of her skirts as fluid seeped out.

"Mmm ..." Sunset gave a content sigh, popping her breast out of her mouth. Twilight and Adagio laid down and placed their arms on Sunset, cuddling up to her before drifting off to sleep.

Author's Note

Danggit, I can't keep misbehaving on my schedule like this. Well, there you go, people, and Wintermist in particular. It's not nearly a full-length story, of course, but it's something.

I'll admit that last scene might have been a bit tacked on, but I thought of the idea and I wanted to include it somewhere.
