Celestia (lactation)

Celestia can't trust you - not yet. She would like to, of course; Celestia would like to trust everyone. But she has a country to run, and that is not a position that allows for naivete. Equestria is always excited by the possibilities of welcoming a new species and learning from them. But just as your potential for good is uncharted, they must also take into account your potential for evil. As princess, Celestia considers it her royal duty to make certain you do not pose any threat to her subjects.

Which is why you are now on your knees beneath her, suckling eagerly at her milk-engorged breasts as she smiles gently at your enthusiasm. Pony milk was known to have certain... effects... on non-magical or low-magical creatures, becoming highly addictive even with relatively low exposure. And because the milk carried traces of the pony's own inherent magic, it was known to cause a sort of mental imprint on those who ingested it. It was not the most elegant tool in Celestia's arsenal, and not always terribly effective since most races native to this world were quite aware of it. But it was definitely the one she enjoyed the most.

As a centuries-old immortal, seducing you had been quite simple, of course. An enticing smile here, a sway of her hips there, the faintest hint of suggestion magic, and a light breeze to carry the scent of her sex to your nose had been all it took. You hadn't questioned the subsequent invitation to suck her milk-laden breasts, and not long after you got your first taste of sweet, rich, warm pony milk you had stopped questioning anything at all. Every mouthful was a precious treasure, the greatest gift you could possibly receive. Every swallow seemed to warm you to your very core, the potent magic of a goddess diffusing lovingly into your body. You moan in approval around the nipple in your mouth, and Celestia giggles softly before once more telling you to have as much as you'd like. For a long time after, the chamber is surprisingly quiet, the silence broken only by the occassional noisy suck, gulp, or encouragement.

But all good things must come to an end, and eventually you fall back to the bed, too exhausted to continue. Your stomach full of milk, and your heart full of love for your beautiful, perfect princess. Seeing the adoring look in your eyes, Celestia knows the process is complete. If you ever posed a threat to anypony in Equestria, you wouldn't dream of it anymore. In fact, with the subtlest encouragement of divine essence circulating in your mind, you are the happiest you've ever been. Celestia smiles, pleased to have helped another troubled soul find peace. By means of a reward for your progress - and to no small enjoyment of her own - her horn lights up with a soft glow as her magic engulfs your eager shaft, pumping you with smooth, even strokes.

Welcome to Equestria, loyal subject.
