OniOniOgre is a size fetish artist who draws giantesses, giant sperm, intersex characters (a.k.a. futanari), hyper-sized cocks, and shrunken people. This artwork covers themes such as breast expansion and overall growth, sometimes up to cosmic dimensions. The end result is not safe for work (NSFW) and explicitly sexually. Normal-sized characters are often depicted looking up at vastly larger ladies from a very low perspective. A few of these giantesses were modeled on Japanese “Oni” 鬼 which are roughly equivalent to English ogres. Oni are often large, muscular humanoids wearing tiger pelts and with one or more horns in the middle of their foreheads. Fans can find this artwork at DeviantArt and Newgrounds. They can also follow OniOniOgre on Bluesky and X/Twitter. Lastly, folks can support OniOniOgre via Patreon, Pixiv Fanbox, and SubscribeStar.
#1) Can you tell the readers a little about yourself?
I go by OniOniOgre. I’m a self-taught artist at the age of 30 that has been drawing size content for around 6 years. I like both sides of the size spectrum – big and small. My favorite subject to draw is sperm cell+shrunken woman interaction scenarios. Giant cock+shrunken woman interactions is a runner up. People probably know me more for drawing massive size differences with an extreme pov.
I enjoy the game series Super Robot Wars. I also enjoy mecha and tokusatsu media. I would say I haven’t scratched the surface too deeply but I love their energy so much and I’ll continue to explore and dive deeper. I partake in a bit of plamo/model kit building. I quite like SD versions of robots.
#2) How did you first become interested in size fetish?
What probably started it was the type of media I stumbled across a young age. It wasn’t erotic to me back then but I was obsessed with it. Seeing something that should be big become smaller and vice versa always sparked something in my brain. Things like Alice in Wonderland and Tinker Bell would always stand out in my mind. I was just fascinated with size comparison both big and small.
It only really clicked over to being erotic when I got access to the internet. Image searching characters from the game “Dead or Alive” lead me to finding giantess collage pics of 3d renders of DOA characters photoshopped amongst cityscapes on VGGTS. From there I discovered more size artists and art on DeviantART, GTSDepot, and later on Sizebooru. For years, I’d just search and accumulate size artwork and have fantasies. Whenever I did draw, I never really tapped into those fantasies.
However, I did start OniOniOgre in 2018 to draw monster girl pinups initially (hence the name) but at some point I thought “Why not draw this thing I’ve always really been into” and it eventually developed into “Why don’t I draw this shrinking-to-sperm-size thing that scarcely has any art that I really want there to be more art of”. That would have been one of my first proper size fetish piece of art: A microscopic woman licking a sperm and being swarmed by others.
#3) What are a few of your favorite art pieces, comics, or stories from other creators?
Anything that does something cool or new with shrunken woman + sperm cells I’ll love. It’s fairly niche, so when its done well, it really stands out to me.
-My favorite artist is Seta/@seta53494366. They frequently create shrunken woman renders/videos with sperm cells amongst other shrunken woman scenarios I enjoy.
-I also enjoy Kiyoshi/@kiyoshi0981 who draws size art with amazing scales and compositions. They also occasionally draw shrunken woman with sperm cells and good amount of sw on giant cock stuff.
-Masough/@masough1 wrote a story named “Sperm Overflow” which has shrinking woman and sperm cell interaction as a main subject matter (as opposed to a small mention of sperm cells). Written content of sperm stuff is super rare and I appreciated it a lot.
-Wizwrites also wrote a story about sw+sperm cells called “Replaced by a Goddess” with a omni focus.
In addition, the following artists all have approaches I really enjoy in size art or have been a huge inspiration art wise: IffyRealms, GtsMayCry7, MMDelight, Ferrous, pectoriah, FlanC20, DigiPotion, West/WMaker777, inksgirls, Ivelacia, Zoey Mini, Weiweimio, Jitensha, CaddyisRaddy, Minutia, hunter_rank_E, Chief, Jodagee, Ochiko, Uru and many more that escape me at the moment.

#4) How would you describe your art?
Sketchy and loose. It’s prob not the best technical wise but the hope is to give people a pov you don’t get to see too often. Subject wise, I like to focus on size comparison. The domination and power aspect to size stuff is secondary to me. For me it was really about “small thing is now big” or “big thing is now small” and how big or small is it in comparison to me or a person and what were the consequences or reactions to that being so. You could say being able to observe or explore something of different size is the fantasy I try to capture in my art.
#5) Do you have any advice for people who want to create their own art?
This can be taken with a grain of salt – I’m not really an expert:
-Aim to draw what you really want to draw, even if it’s niche. If you are passionate about what you’re drawing, it will be your main drive.
-Try not to compare yourself to others. “Comparison is the thief of joy”. It’s probably over said but I’ve seen a lot of artists get stuck here.
-If you’re having fun, you’re probably doing something right.
#6) What rewards do you give to Fanbox, Patreon, and SubscribeStar supporters? Are there any upcoming projects you would like to mention?
I post exclusive/timed art works and hold polls on my Patreon Discord to let supporters have some input on what I draw. Currently, I’m doing a series of Halloween drawings that supporters have submitted scenarios for during this October.
