Growing into Her Role

Dear Princess Celestia,

I... still haven’t managed to stop them. My breasts are so large now that they cannot be classified with the usual measurement system. The best way I can describe them is as small beach balls, though they’re so very soft even with their incredible heft and decent perkiness.

The pleasure I got from them before is so much stronger now, with each little brush of anything against it tingling a lovely warmth across my body and making my pussy start to leak. I have learned the more casual terms around sex recently, and my thoughts are going crazy, my libido being so high now that I need to masturbate several times per day in order to keep even a semblance of control in the rest of my life.

The weight of my breasts constantly reminds me of their prominence, with the hearty bouncing and jiggling as well as the tremendous strain they put on my back, forcing me to get an enchanted sports bra from Rarity that expands as my breasts do in order to keep it all at an even partially manageable level.

Even with that cover, my tits feel so good when they’re resting on a table, which they have to do quite a lot to keep my back strain from getting any worse. Note that I have tried levitation before, but the magical tingling I get across the massive entirety of my breasts just feels too good for me to do anything but thrust my hands into my pussy and masturbate until I’ve orgasmed multiple times.

With the tables though, it’s not as quick to start, though the latent pleasure eventually just makes me have to finish off right there. It’s even worse when there’s others with me, as they can clearly see my pleasure, and that just makes me even hotter and wetter, so I try not to stay around them for too long as I know I’m eventually just going to go off right in front of them and they’ll all see it...

*huff*

I-I know that cause it’s happened before... A-and I came a lot harder than I ever have before with so much juice splattering all over the throne...

My friends don’t remember it though, cause I wiped their memories of it.
B-but it’s for the best, right? I mean, they would be constantly distracted, and they’d see me as an idiot and they’d try to get rid of me, o-or they’d think less of me and would try to stop me from dealing with others’ friendship problems!
You do understand, right?

Um, anyway... I’ve blocked access to the Palace (with magic to prevent window-crashing and teleportation since I really don’t want anypony getting in here) with only Spike here and the occasional visit from my other friends (and Trixie, who still manages to get inside somehow, and I can’t help but think she still remembers that stuff I removed from the others’ memory).

I do know that I’ve been a little... rough on Spike recently, having him do pretty much everything for me, as I can’t really do much with much accuracy or without getting so horny I have to rush to my bedroom to prevent myself from cumming ~~all over~~ in front of him.
He should understand, though; his mommy’s having a pretty rough time.

On another subject, I’ve noticed that my breasts have started lactating when I pinch them, which happens a lot when I masturbate, ~~leaving white jets spurting from my nipples during my orgasm, which splatter all over my body and huge tits, making them feel so warm and wet~~–Ah! I mean, which happens only when I’m pointing them straight into buckets to fill them with my ~~sweet, creamy,~~ delicious milk.

Umm, I-I’m sorry for all the crossed-out words; I’ve been writing this letter for nearly an hour and all the recalling of those lewd things are doing strange things to my head...

I’ve been trying to figure out a counter-spell to this ~~lovely~~ madness, but with my massive boobs getting in the way, it’s rather difficult. I also haven’t really asked anyone else to help figure it out, because I don’t really trust that they won’t either screw it up or prank me by making it worse (I think Trixie especially might).

I know that I’ve mentioned Trixie quite a bit, and I think that’s because she’s so... ~~sexy~~, er, confusing, so my mind is constantly trying to solve her.

Right, anyway, I do trust you with creating a counter-spell, so if you can, please help me.

Your Faithful ~~slut~~ Student,
Twilight Sparkle
