Growing into Her Role

Dear Princess Celestia,

Remember how I was saying I wanted to pause at E-cups?

Well, that didn’t quite happen. It seems the spell lasts longer than the book said it would, and so now my breasts are all the way to I-cups. Not that that’s particularly a bad thing, of course, it just wasn’t what I had planned before, ~~even if I told my friends otherwise~~.

And they are starting to feel rather nice, as what was previously a nicely fitting weight is now quite hefty, with their moderate bounces with each step I take grazing them against my shirt making me feel rather warm, especially right below my tummy.

When I had some private time, I started to experiment with that, and found that my vagina was getting very hot and puffy, and beginning to leak some liquid. I then touched it, and it started getting even hotter and leaking even more while my heart started beating faster, though it all felt very good for some reason.

Continuing the experiment, I pushed my fingers inside of my vagina, and it made my entire body feel like it was heating up while something in my lower abdomen started to tense, and I began to moan, though it was higher-pitched and more... elated? than usual. However, it still felt very good–incredible, even–and I couldn’t control my moaning as I pushed and pulled my fingers in and out of my vagina, the heat across my body getting hotter and the strain in my abdomen getting stronger, until...

Well, my emotions were getting a little crazy at that point, so I can’t quite recall everything that happened very well, but from what I can remember, the fluid coming out of my vagina got pushed out with more force and in higher volumes and the tension suddenly went away, though it was more of an explosion than a simple disappearance. All of those sensations felt amazing for some inexplicable reason, and I started screaming out of ecstasy, though it stopped after several seconds, leaving me in an exhausted haze that was very blissful.

The only problem with all of that was my scream was loud enough to alert everypony (and dragon) in the Palace, so Spike, Starlight, and Trixie quickly shot open the door... only for the latter two to slap their hands over Spike’s eyes and blush heavily while looking away. I asked them what was wrong, but Starlight just teleported Spike away and yelled at me for almost ‘exposing him to my sex life’, as she said.

I asked what she meant by that, and she replied the same, leaving us in a conversation that I don’t think either of us understood what the other was talking about. I did eventually notice Trixie’s near-hysterical look, and I asked her about it, which made her break down laughing while she muttered about me being very innocent and not even being a ‘virgin’. She did eventually calm down (somewhat) after nearly a minute before asking me if I’ve ever masturbated before, which I replied that I didn’t believe so, causing her to break down again and have to hold onto Starlight’s shoulder for balance while laughing about me not even knowing what that was, and Starlight herself got an odd mix of humour and disappointment(?) as she looked at me.

Starlight then seemed like she was trying to say something, but wasn’t able to, making Trixie lead her away while shouting back at me to ‘get a life’ (whatever that meant) and closed the door behind her. All of that happened four hours and thirty-two minutes ago, and I still have no idea what they were talking about.

I’m going to have to talk to them later, and possibly some of my other friends to find out what they were talking about, but rest assured, I will find out!

Anyway, my breasts still feel a little sensitive, and certainly too big for my current bra, so I went to Rarity to get another one, though I was only able to get measurements for it as she didn’t have any that size in stock, and she said she would get it to me by tomorrow. I did have to restrain talking about that weird stuff Trixie was saying about masturbation, as I took Spike with me and I didn’t want to talk about that in front of him because of how much of a problem Starlight said that was.

Right now though, I feel my breasts are at a good size, what with their heft and softness along with the tingly pleasure, even if my back is starting to hurt a little, so I think I’ll keep them at this size for a while. Er, if I can that is; last time didn’t quite work, but regardless, I shall definitely try!

…Right after some more experimentation...

Your faithful student,
Twilight Sparkle
