"...'The Bottled Night,' huh?" Shi mused thoughtfully.
"Yes!" Luna beamed proudly. "Think about it, dear sister. This way not only will I be able to help our subjects in a place where I can exercise my powers to their fullest..."
"...but you won't have to worry about getting carried away again, will you?"
Luna's face turned beet red, and shi shook hir head softly. "You didn't have to say that out loud, you know."
Tia smiled and ruffled hir younger sister's starry, sparkling mane. "I know, but it's an older sister's job to tease their siblings. Besides, there's nothing wrong with what you did! You just needed a bit of moderation. I thought Fluttershy looked marvelous at that size."
Luna hid hir face, but Celestia saw the subtle and unconscious nod of agreement, the two busty alicorns' towering cocks giving a series of surging, tremendous throbs at the thought. Cum began to drool from their flared tips, splattering in messy, dense globs to the floor below. The Princess of the Sun laid a gentle hand on her sister's shoulder. "So anyway, you were saying...?"
Their bodies slowly swelled together, the air filling with a fragrant perfume as their scent clouds filled Luna's bedchambers. The drifting, billowing tendrils of ebony and rainbow musk swirled together in a wild riot of color, the two sisters producing aromas that looked as wonderful as they smelled. Celestia stretched hir legs over the side of the bed and sighed relaxedly, hir ballooning breasts beginning to release twin streams of sweet, bubbling milk from hir puffy nipples.
"Well, anything that happens there is only limited by my own imagination, so I thought I could have some fun with it." Luna explained. Celestia's fingers wound around hirs and shi pulled hir sister in close, their huge breasts mashing together warmly and continuing to expand with rubbery, pulsing booms. The stimulation made Luna begin to lactate as well, the sisters making a leaky, creamy mess of themselves. "It'll help me socialize and learn some... self-control, as you said. With your help, I could make it so that the ponies who need my advice would be drawn to it naturally. It'd be much easier on me if I didn't have to search them out on my own!"
"And you're sure you'd be able to handle the responsibility?" Celestia asked. "I wouldn't want you to get overwhelmed, after all..." Hir hands wandered downwards, wrapping around the base of Luna's titanic spire and beginning to slowly pump it with slick, wet slurps. It only took a few strokes before Luna began to properly orgasm, the two ejaculating in unison like a pair of frothing geysers.
"...A-About that." Luna murmured, hir voice shaking as shi tried to steady hir breaths. "You see, I was thinking..."
Celestia leaned in to listen, kissing hir beloved sister's cheek. They were painting the room with alicorn sperm.
"I was able to find redemption, with the help of your friends. In a place where I hold all the power, and we can safely keep those who might cause trouble, who's to say that we couldn't reform other... misguided souls?"
Both of them were silent for a moment, savoring the feelings of their climaxes and growth, touching each others' bodies in languorous, loving intimacy. Celestia considered the thought, hir hands roaming freely.
"All right." Shi said. "That sounds like a fine idea. I think I have just the pony in mind for your first job, too."
Luna tilted hir head quizzically. "Who?"
Celestia pulled hir sister up into hir lap, wrapping hir arms around the Princess' massive, carriage-sized bust from behind and grabbing at hir nipples with a suddenness that made Luna gasp. The Sun Princess' gigantic equine penis pulsed between Luna's legs and ballsack, lifting hir up and tilting hir back as if shi were on a huge seesaw, and Luna gasped in delight, cumming even harder. The sound of spraying jism was deafening, like an intense downpour on a tin roof, globs of semen splattering everywhere. "...You remember Candence's little adventure out in the Crystal Empire, don't you? And how Twilight and hir friends had to step in last week to solve it all?"
It took a moment, but Luna nodded and mewled a quiet affirmation, hir sister's molesting hands mercilessly ravishing her swelling figure and making it difficult to do more than writhe in delight. Celestia giggled, kissing hir beloved Princess on the tip of hir horn. "Well, let's just say Cadence sent me a very interesting memento afterwards. I'll show you later, okay?"
Their lips pressed together, tongues dancing in and out of each others' mouths, and in no time they were lost in their blissful passion. The two of them simply kept growing, of course. It was an alicorn's prerogative, after all, and it took them very little time and effort to fill up the bedchambers with their combined size. Their bodies seemed to fizzle with sheer pleasure, their lustful cries echoing through Canterlot Castle's hallowed halls. The Princesses very rarely had private time to themselves, and they were going to make the most of it!
Just as they were about to burst through the walls, though, Celestia pulled back and gazed into Luna's eyes. "All right, dear. I get what you're going for with this new bar of yours, but there's one last thing I simply must know." Hir horn began to glow, and the picture from before floated into view, surrounded by an enchanted cloud.
"How'd you take a photograph of something that only exists in a dream?"
