Author of Breast Expansion Stories

I'm a breast expansion author, meaning I write about growing breasts (and occassionally butts). My shtick is that I write about the process of growth in meticulous, a little excessive detail.
Feedback is always appreciated :)

Tube tops are by design meant to be sexy, so it see it as my obligation to fill their fabric with even more sweat breast meat (or well, write about the process). #breastexpansion

プロフィール画像プレゼント企画の五枚目、最後の一枚です
こちらはけものフレンズからのハシビロコウです
けもフレのキャラクターを描くのは何気に初めてかもですな
ま、結局ウルトラ化しますけどね
Here is the fifth and last PFP for the PFP raffle.
This is Shoebill from Kemono Friends.
It is actually my first time drawing a character from this series.
Well, I still ultranized her though.

I can't imagine a situation where one would wear such a short sweater over a blouse since it's too warm for hot but not warm enough for cold weather. It sure makes for a fun #breastexpansion exercise though.

The story of Maddi, that curvy redhead I draw all the time, started 18 years ago with a story @soylentorange.bsky.social and I began. It's all done now and all the chapters, side stories and accompanying art have been compiled into an ebook you can purchase here!

こちらは会場でスケブを頼まれた方用に描いたものです
ロザンナさんが好きとのことでしたので、
盛っても良いかと確認し、許可得たので盛りました
This is a sketchbook request I received at the event by a customer and drew there.
He liked Rosanna, so I asked if I could ultranize her a bit and this was approved, so that is what I did.
