Twilight sat down in the bed with Celestia, purring as she felt the princess wrap herself around her and rested her head on Twilight’s shoulder. She smiled at her, giving her a quick peck on the cheek before lifting up the book the princess had given her. It had been a week since their run in with Cadance, and Celestia’s heat had finally run its course, and thus they had stopped rutting like animals. As promised, Celestia had retrieved the book she had told her about, and now they sat comfortably in her bed. Twilight took a moment to look over the book, taking in the beautiful design on the cover, depicting two alicorns kissing under the gold lettering of the title, which read…

“A Study on Alicorn Matting and Reproduction, by Heart Song…hm, I have never heard of this pony before, did you know her Tia?”

“Not personally, she was a personal advisor to Cadance’s mother, and wrote many lovely works. Sadly this is the only book that I have left of hers, the rest were lost long ago.”

Twilight noticed the sad look that came into her student’s eye, and nuzzled into her to try and comfort her. After a brief kiss, Twilight opened the book, turning to the first page and began to read.

Divine alicorns, a race of ponies not well understood by most of the world at large, but this book will try and help those who are lucky enough to woo or be wooed by such beautiful creatures.

Unlike the most pony races, the Divine alicorns cannot bread with the other races by normal means. Even the mortal alicorns, as mysterious a race as their Divine counterparts, can bread with other races, but not so for the Divine Alicorns. If a Divine wishes to mate with a mortal, they must give a piece of their own magic to their mate to make them compatible with the Divine, and thus able to mate with them and have children. The magic introduced into the mortal will change them drastically, altering their size, increasing their magical power, and extending their lifespan.

Depending on the type of relationship, the mate’s size will either be larger or smaller then the divine alicorn in question. This all depends on who is the “male” in the relationship, for all divine alicorns as we know of now are female, and most societies do not discriminate against mare on mare relations. Depending on who is the “male” in the relationship will determine who is the larger of the two, as the “male” will be the one filling the role of protector when their mate begins bearing their child. The magical growth is due to the magic being given by the alicorn, it integrates itself into its new host and becomes a part of them and strengths their already existing magic near tenfold. The final change is the extended life, being a mate of an alicorn means knowing life as they do, gazing through the eyes of an immortal.

Caution must be taken when making the decision whether to go through with the changes or not, for it means outliving everypony you’ve ever known and cared about. Your friends, your family and all those you have come to know over the years will die around you, while you march on through the endless flow of time at your lover’s side. It is a hard decision, choosing one love over many, and not many are willing to make that decision.

Reproduction at this point is as normal as it is for anypony, but there are some differences that should be addressed. One, when an alicorn become’s pregnant, their sexual apatite increases exponentially. Under no circumstances are you to deny you partner their wants if they suddenly ask to have a role in they hay, trust me you will be doing yourself and your kingdom a favor by complying with your mates desires. Mood swings will also be potential dangerous, for like unicorns Alicorns are prone to what are called “rage shifts“, but said rage shifts are a lot more destructive then a unicorn rage shift, and last a significantly longer time.

However unlike unicorns, Alicorn sifts don’t just deal with rage. Throughout the course of the pregnancy your alicorn lover will go through a shift of every emotion capable of being felt, and it is highly important that you not panic during this stage, it is all perfectly natural.

The final thing to note is that during the latter stages of pregnancy your mate will most likely be unfit to go about their normal duties, and will temporarily lose control over the source of power that they control. During this time such duties and control of said power will temporally be passed onto you, I and other researchers don’t know how this is done, but from what we have gathered controlling of said power can be a very rewarding experience. Also don’t worry about not being able to handle said power, as stated before your own magic will have been strengthened to match theirs, so there is no need to worry.

As for what kind of offspring this kind of mating will produce, from what I have discovered the child is always born as an alicorn, and comes with unique characteristics of their own. Unlike most ponies, divine alicorn offspring are born with the same talent and cutie mark as the divine parent, though due to how young the alicorn offspring I have been studying is we have yet to figure how much control they have over their talent, and whether or not they have as much control over it as the divine parent.

Regardless of your choice on whether or not to stick by the side of a divine, I hope this has helped you better understand the divine alicorns a bit better in regards to their matting habits.

Twilight closed the book, her face a mask of questions. She turned toward the princess, her eyes locking with the solar monarchs as a question formed on her lips.

“Tia…the way this is written, it makes it sound like there were more divine alicorns then just you and Princess Luna. I need to ask…were there other alicorns like you two?”

Celestia stopped, a look of concern washing over her face. “Should I tell her…” she thought. “I don’t see what the harm could be but…but if I tell her it will change everything, she…she will know about everything I have done…about everything I have had to hide…I can’t tell her but…but I have to tell her something.” She took a deep breath, steadying herself before speaking.

“There used to be others…but they left long ago, we had disagreements that led to them seeking other places to live, rather then stay here in Equestria. It was painful…losing friends like that…”

It was a lie and she knew it, but it convinced Twilight, who mistook the hurt in her voice for that of loosing her friends instead of over the lie she had told.

“Shh my faithful student,” cooed Twilight, gently nipping at the princesses neck as she slowly rolled her onto her back. “Just let your teacher take your troubles away.”

Celestia groaned as Twilight slowly nipped along her body, letting her old troubles wash away as the sensation of pleasure washed over her. Twilight went for her teats first, slowly licking and nibbling along the sensitive nubs. Twilight grinned at the cute moans escaping her student’s lips, slowly circling her tongue around one nub before gently taking it in her mouth to suckle. Twilight slowly pulled on the teat, letting it leave her mouth with a gentle popping noise before going after the next one.

Celestia moaned loud, but then stopped as she felt Twilight slowly crawl up her, looking down to see Twilight looking confused.

“Tia…um…I know this may be kind of sudden but-” Her horn lit up, and a small box levitated from behind the pillow Celestia was laying on, opening up to reveal a diamond coated horn ring, complete with a miniature version of Twilights Cutie Mark laid out in amethyst. “-I have known you for most of my life, and love you for most of that time. I can’t honestly imagine living my life with any one else but you, so please…give me the pleasure of making myself forever yours, and you forever mine.”

Celestia was speechless, the earlier arousal washed away by the utter shock this bombshell had produced. What was she to do…it had only been a month but…

“Come on Cele,” She thought, “you know what she’s talking about. You expressed it before when you started nipping her before your fist time. You have loved this mare for longer then you care to admit, so what are you going to say to her now that she has asked the one question you have been dying for your entire life.”

“…Yes.”

Author's Note

I think I have set a record for myself, I put even less sex into this chapter then the last one, I will understand if you all beat me to death, but I hope you can understand why I did it. And yes, the next chapter is going to be of them getting married.

Also for those wondering, I am in the middle of working on a Tumblr page based on these two, it will feature Dominant Teacher Twilight Sparkle and Submissive Student Celestia, I will post the link once it is done, and then you can ask all your naughty little questions.

Oh and if any one is curious, the book was written during and after Cadance was born, which is why it mentions the offspring in question being too young.
