2026/07/03 Doodle Day (Various OC Boobie Drawings) / 突発落描き（オリキャラおっぱい落描きまとめ） (Patreon)

Hello researchers.

Have you all taken your dose of boobium today?It is an important nutrient to intake daily you know.There is such a difference between having it or not.Do remember to get your daily amount!

So today I thought about bringing you all lots of boobium to intake.Very important, I say.If I can prescribe it, then why not do so, right?

The doodle compilation today is something that just kind of blew up in number out of nowhere.I posted a question not really thinking too much about it on Bluesky, which was “think about and tell me what you feel are the most appealing boobs within five seconds of thinking” and I received more replies than I was expecting.Just for reference, I wanted to draw a few, but it ended up being a lot more than that, you know, one of those kinds of situations.I did not plan to take this much time on it, but...it technically could be used as promotion for my OCs, so I say why not.Some merits came out of it I suppose.Moreover, communication that sparks from boobs is absolutely incredible anyway.

So okay, let’s just get right into the cake.There really are a decent number of them.I will post these in the same order I drew them.

1. “Big”

No seriously, this one word was their reply.I was unsure of the exact size, so I went with my definition of “big” with Riana.Like for normal people it is quite large, but to us well trained warriors, this is nada.Good for starters though.

2. “Boobs that are big enough to cover her entire torso!”

I went with our girl whom we all know by now, Chinova.Her boobs do just cover her torso, so there really was no reason not to draw her.Though this kitty covers her upper body with her lower body, however that works...

3. “Armfulls, about as far as her arms can reach, barely touching the edge of nipples.”

This term “barely” does make a difference, I completely understand.It does go down to these kinds of body styles radiate the most when paired with “inconvenience.”I went with Souka for this one, her size pretty much perfectly fits the description.

4. “Big, full, and round! Bigger than beach balls! Bigger than the torso!”

The list of adjectives do help a lot when imagining the size.Sizes that cover the torso sure are popular, and I agree.I knew this researcher likes Toyoko, so I went with her.There should be no problem here for boobs being a bit larger than the description, right?

5. “Boobs big enough that they're just barely hovering above the ground. Big, thick nipple bumps, too!”

Sizes that just barely hover above the ground are wondrous for sure!I would be so willing to lay on the ground and have them hover above me.Big thick nipples are also a great trait, so good choice there.With that, I thought Chouka would fit these descriptions, so here she is.

6. “Hefty, smothering, soft. Good to get lost between.”

At first, when reading the first half, I thought they were talking about a fairly “normal” size, but that clearly was debunked with the second half of the sentence.With that it was obvious we needed boobs that were bigger than the body.This is where highfolk like Pueria fit the job.She even has an entrance to enter the maze, so feel free to get lost in it.

7. “A size that just covers the belly, somewhat hanging down but still expresses its fullness making a shape like a kitchen bowl. Her areola is filled up and her thick nipples are erect, enough to break someone’s jaw.”

The details of this one were amazing, extremely easy to imagine I would say.Though on the other hand it made me wonder who would fit this one.After some thought, I thought Lenfa would match it fairly well, so I call her to come.However, she seemed to be in quite a horny mood, so bad timing on her part (and good timing for our parts).

8. “Would probably say a pair that covers the torso.”

So technically I would say this is similar to other torso covering one, but I thought this time one that would cover up even the pelvic area would fit, therefore I had Renka show up.She is even nice enough to show what she is hiding under her titties, that is what I expect from an adult woman like Renka.Not saying where, but it would be nice to put my hand there.

9. “Too big for [context]. So, just outgrew a shirt, or having difficulty fitting through a doorway, or larger than the person's armspan, or overfilling a room, etc.”

Now I must say this was a very intriguing perspective.As this does not exactly emphasize the actual size of the boobs, but defines it through an item that is affected by it.Overflowing in a bra, buttons on a shirt about to fly off, hits the edges of a doorframe, etc.It expresses the size of the breasts, making this one very nice.So here is Midoni having trouble getting through a doorframe and looking pissed off.It is one of those “your room’s doorway is too narrow, do something about it” types of situations (splurt).

10. “Large enough that they can't fit through a doorway together, every time they lean forward even a little they press against the ground, like 2 giant beanbags attached to them, stuffed to the brim with milk.”

Ah, boobs with lots of traits.I admit it is fantastic.Definitely a size that would be wonderful to dive into.I thought Miyuna would work in this case.She usually has some support to keep them up, but without them, they basically do touch the ground.

11. “Glass pressed boobs will always multiply attractiveness x10“

I agree.I really do wonder why boobs pressed on glass look so appealing.Especially if you can see the shapes of the nipples too.So I asked Rhosha, who I had no doubt would do it for us.For the better or for worse, she did without any embarrassment.That is the big sis Rhosha we know and love.

12. “Gargantuan, massive, full of milk and very comforting uu”

We have an order for milk, I will add a few packs on the plate.With this size, I doubt anyone would have to worry about milk shortages any more.Certainly will be great for humanity, so such merits I say.For this one I thought Bihomura would work, so she was summoned.Would be interesting to see how much leaks out if we all jumped on her.

13. “Boobs that never stop growing, of course!”

The cheat answer, of course this would be the best one.Boobs that allow you to enjoy different sizes as time goes on, definitely a gift from the heavens.The one that seemed pretty obvious for this one was Naya, so I had her come by.Okay, I see that the shirt does stretch a lot, but better to find a new one before it rips.

14. “When the top is just a little too tight and the boob overflows a bit!”

This was another one that did not depict an actual size but emphasized it through other items.I guess this means this person would be able to enjoy “normal sized boobs” too, that is nice.So since Alis comparatively has “normal” sized breasts, I had her try it out.Looking here though, Alis has a decent rack you know, though it is difficult to tell with her big thick robe.I always wanted to grope boob meat that flows out of a shirt, if you know what I mean.

15. “Tiddy big, seen from behind”

Backboob is excellent, no questions asked.Being able to do this and not makes such a big difference.I mean it allows you to enjoy both boobs and booty at the same time; what is there not to love?So here is Aira who can do this with ease.She is definitely seducing someone.Well, time to dive in.

16. “Breasts that reach down to the top of the thigh and protrude forward significantly.”

So basically super torpedo boobs.Exquisite.This comment also mentioned wanting to be hugged by boobs like that, but that is certainly a pro in torpedo boobs.I thought Meuna would work for that, so she came for that.She is wearing an a$$ design T-shirt, but who cares with boobs like that?

17. “Boobs that cover up their behind when leaning forward”

So here is my 5 second thought process of appealing boobs, but I went with the “posture” route.I just feel like these kinds of boobs that hang down low when leaning forward kind of communicates with the environment, if you know what I mean.And plus, when the boobs hide what is behind them, it emphasizes their size right?So it is one of those using the environment as a catalyst to become even more appealing.Anyway, I had Mafuni do this one.How lewd (direct attack).

Okay, that is about it, all 17 images.There were various other replies too, but it would take a lot of effort to do all of them and some were pretty difficult to draw, so I just did the ones I wanted to do.I mean, I never even said I would draw any of them in the first place, so...These types of things are done through spontaneous emotions, nothing more.

What I noticed this time was that even with everyone liking humongous boobs, there is still a lot of variety within that theme.That means you cannot just summarize it into one trait when it comes to hyper boob fetishes.And plus, I had everyone think about this for only five seconds, right?I bet everyone will come up with a different answer if I asked again on another day.Hyper boobs have such an infinite range in sizes (literally) that everyone has their own preferable range I think.Which I consider another reason why it is so interesting.Lots of content to research regarding ultranization in the future, I guess!

Alright, that is all I will be bringing to all of you today.Maybe this was fairly satisfying?Thank you to all of you who reacted to that original post on Bluesky!If I did not have to go through that temporary ban I would have probably been able to react faster, but no point in mentioning that now.

Well, time to end this article.Next post...will probably be of something I wanted to try out, so I will post that when ready.Oh, and I have a few commission pieces in the works too, so once those are done I will bring them over here, obviously!Hope to see you all soon again!

Enjoy.

研究員の皆様、こんばんは。

今日のおっぱい分って摂取できました？毎日欠かせない栄養素ですよ。これがあると無いで健康状態が全然違いますからね。ちゃんと抜かり無く取るんですよ。

ということで今日はそのおっぱい分をたくさん分け与えようと来ました。やはり大事なものですからね。自分からも処方できるものは処方しておかないと。

今回の落描きまとめは…成り行きで気がついたら多くなっていたものですね。ブルスカであの一時停止事件の直前に適当に発信した「5秒以内で好きなおっぱいを思い浮かべて教えてください」みたいな投稿が思いの外回答が集まって、なんならちょろっと参考程度に何枚か描こうかな―って思ったらなんだか結構な量になっていたというやつです、はい。本当はここまで描くつもりは無かったのですが…まあオリキャラの…宣伝？にはなったかもですし、良いとしています。おっぱいを通じて発生するコミュニケーションは最高ですからね。

ということでぱぱっと行っちゃいますね、割と本当に多いので。描いた順でお出しします。

１．「大きい」

マジで一言回答でしたので、どれくらいわからず個人的な感覚で「Big」程度であるリアナを描きました。一般的には大きいですけど、まあ自分らみたいな鍛え上げられた戦士からしたら小さいですよね。まあ序の口としては丁度良いでしょう。

２．「上半身を隠す程度」

皆様ご存知のってことでチノヴァにしました。実際ちょうど上半身は隠せていますから、描かない理由がありませんね。もはや下半身も上半身を隠してる状態ですが、この猫は…

３．「腕がギリギリ乳首を触れない程度」

この「ギリギリ何かできない」ってのが良いポイントですよね、わかりますよ。やっぱりこういったすごい体型は「不便さ」があるとより輝きますから。ということで爽火（そうか）にしました、ちょうどそのくらいの大きさですしね。

４．「大きくて豊満で丸い、ビーチボールよりでかく上半身を隠す！」

細かく形容詞を使ってきますし想像がつきやすいですよね。やはり上半身隠しは人気です、自分も好きです。ただこの研究員は豊小（とよこ）が好きと知っていたので彼女にしました。少し大きめでも問題はないでしょう。

５．「地面より少し浮く程度の大きさかつ服の上からもわかる程のデカ乳首」

ギリギリ接地しないサイズも良いですよね～～、地面に横たわっておっぱいを上空に持ってきてほしいです。デブ乳首も好きなのでそこは良い指定でしたな。ということで蝶科（ちょうか）が適切かなと思い彼女で行ってみましたぞ。

６．「柔らかく巨大、埋め尽くされる程大きくて迷子になれそう」

最初はまあまあの大きさと思ってたら突然の「迷子になれそう」でサイズ感が全然変わりました。そうなると明らかに本人よりだいぶ大きくないといけないので、そういう時こそ天族のプエリアさんの出番ですな。ちゃんと入口も用意していますし、お好きに迷子になってくだされ。

７．「へそを隠すくらい大きいやや垂れた乳、しかし中身が詰まっているかのようなお椀型。充血した乳輪と顎が外れそうなくらい勃起した乳首付き」

いやー細かい部分まで説明があって想像しやすいですね、参考にしたいやつです。逆に詳細過ぎると誰にするか迷うこともありますが、今回はまあレンファが合いそうかなと思って彼女を呼び出しました。ただちょっと発情中だったみたいなので、悪いタイミング…良いタイミング？だったかもですね。

８．「上半身を完全に隠す大きさ」

厳密には上の上半身隠し程度と似ているのですが、今回は股を含めて隠すくらいが良いのかなと思ったので恋香（れんか）にしました。ちゃんと下も見せてくれて優しいですね、さすがは大人の女の恋香。どこにとは言いませんが手とかを突っ込みたいですね。

９．「〇〇より大きい乳」

これはね、なかなか良い視点だと思いました。特定の大きさを示さず、周りの何かを基準にするのは秀逸ですね。ブラより溢れてる、シャツのボタンが弾け飛びそう、ドアフレームに当たるとかそういうの。サイズ感がより強調されるから良いですよね。ということでドアフレームにおっぱいが当たってガチギレしそうなミドニをどうぞ。君の部屋のドアフレーム狭すぎ、ってやつですね（絶頂

１０．「ドアフレーム正面から通れず、方房ずつ入れる必要があり、母乳たんまりなデカ乳」

様々な特徴を取り揃えたおっぱいですね。素晴らしいと思います、はい。飛びつきたくなるやつですね。これなら美優奈（みゆな）かなと思いましたのでそうしました。いつもは支えがありますが無くなるとまあなんとか地面に付きますよ。

１１．「ガラスに押し付けられているデカパイ」

わかる。ガラス越しに見るおっぱいってなんであんなにえっちなのでしょうね。特に乳首の形とかも見られる状態であればより素晴らしいですな。なのでふっつうにやってくれそうなローシャを呼びました。はい、照れることもなくやってくれました、さすがローシャ姉さん。

１２．「巨大で豊満でミルクたっぷりで落ち着くデカパイ」

ミルクの指定がまた入りましたね、何パックかつけておきます。これだけデカければミルク不足にはならなさそうですね。そこも人類のためになりますし良い点ですな。美焔（びほむら）が適切かなと思いましたのでこうなりました。みんなで飛びついたらどんなに噴射されるか気になりますね。

１３．「成長し続けるおっぱい」

これはズルい、どう考えても最強の答えじゃないですか。時間が経つにつれ様々なサイズが楽しめる最高のおっぱいですな。これが一番わかりやすいのはなやのおっぱいなので彼女にしました。いくら伸びやすい生地でもそろそろシャツは変えましょうね。

１４．「シャツが少々きつくておっぱいが溢れ出す程度」

これもまた特定のサイズを指定するのではなく周りのアイテムにより強調をベースにしている面白い回答ですな。これならある意味「一般的なサイズ」のおっぱいでも満足できそうで良いですね。ということなので比較的一般的なサイズのありすにしてみました。こう見るとありすって結構あるんですよね、いつもはデカイローブで隠されていますが。シャツから溢れ出る乳肉って揉みたくなりますよね、見た目的に。

１５．「後ろからも見られるくらいでかい乳」

裏乳は至高。以上。これができるとできないで雲泥の差がありますね。お尻とおっぱいが同時に堪能できる素晴らしい状態ですから嫌いになるはずありませんな。ということで余裕でそれができる愛楽です。これはどう考えても誘っていますよね？ガバっと行きますか…

１６．「太ももの上部分まで届き、遠く突き出るおっぱい」

要するに超ロケットおっぱいですね。素晴らしい。コメントではそういうおっぱいにハグされて包まれたいとのことでしたが、確かにロケットおっぱいはそういう魅力がありますよね。それなら明佑成（めうな）が良いかなと思いましたので呼んできました。クソダサTシャツを着ていますが、そのおっぱいであれば文句言う人はいませんね。

１７．「前かがみで色々裏が見えなくなるおっぱい」

最後にウルトニの5秒思考の至高おっぱいですが、こういう「体勢」を思い浮かべました。前かがみで遠く下へ垂れるおっぱいってなんかこう、環境と溶け合っている感じがしてなかなか好きなんですよね。それにこうすることで本来見えてた部分が隠されるとそれだけ巨大って感じますし、ある意味また周りのなにかを触媒にして魅力爆発してるみたいな。まあとりあえず真普荷にそうしてもらいました。えっちだね（直球

はい、ということで今回は17枚としました。他にも色々回答をいただいたのですが、全部描くと大変でしたし描き辛いものもあったのでやりたい分だけにしました。そもそも描くとは一言も言ってませんでしたからね（笑）こういうのはノリと成り行きで出来ていくものですよ。

今回感じたのはやはりデカパイ好きでも様々なデカパイの好みがありますよね。一緒くたにできないって訳ですよ、超乳フェチも。それに今回はその場で5秒で考えてって言いましたが、多分別の日にまた聞いたら変わりますよ、回答が。超乳ってサイズの幅が広い分好みの振り幅も結構変わるもんだと思っています。それもまた面白い理由でもあるんですけどね。まだまだウルトラ化について研究できることは多そうです。

さてと、今日のところは以上とさせていただこうと思います。なかなか満腹になれるんじゃないですかね？多分。あの投稿に対して反応してくださった方々はありがとうございます！結構自分からの反応とかも時間がかかってしまってすみません。一時停止期間がなければもっと早かったんでしょうけど、ま、そんなことを言っても仕方がありませんね。

ということで終わりにしますか。次回は…ちょっとやってみたいことを思いついたので、できたらそれを投稿しちゃいますね。あと依頼絵も何枚か予定があるので、そちらもでき次第公開しますのでお楽しみに！またすぐにお会いしましょう～！

では。
